Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and in particular to a PCB board for smart glasses. Background Technology

[0002] With the development of smart wearable devices, smart glasses, as a new type of terminal integrating display, communication, and interaction functions, are receiving increasing attention from the market. To achieve a multifunctional, highly integrated, and portable design, smart glasses typically require the integration of small, fully functional, and highly interference-resistant circuit modules. Traditional smart glasses PCBs are limited by space constraints, resulting in large boards, complex wiring, and numerous peripheral components, making installation inconvenient and prone to accidental touches. Furthermore, the complex circuit design can easily lead to signal interference, affecting device stability and user experience.

[0003] Therefore, there is an urgent need for a PCB board for smart glasses that is more compact, easier to install, and has good anti-accidental touch and anti-interference performance, in order to improve the overall performance of the device and the user experience. Utility Model Content

[0004] The main purpose of this invention is to provide a PCB board for smart glasses, which aims to achieve a highly integrated PCB board structure, improve structural strength, and reduce board size for easy installation.

[0005] To achieve the above objectives, this utility model proposes a PCB board for smart glasses, comprising a circuit board body, mounting portions on both sides of the circuit board body, an array of multiple circuit elements on the mounting portions, a plug-in portion at one end of the circuit board body, and a connecting portion at the other end, wherein the mounting portions are provided with a first mounting hole through the plug-in portion and a second mounting hole through the connecting portion.

[0006] A connecting block protrudes from the circuit board body, and a touch unit electrically connected to the circuit board body is provided on the connecting block.

[0007] In one embodiment of this application, the plug-in portion includes a plug-in end and an abutment groove, and at least two abutment grooves are provided, with the two abutment grooves respectively connected to both sides of the plug-in end;

[0008] The abutment groove is recessed on both sides of the circuit board body, and the abutment groove is arc-shaped.

[0009] In one embodiment of this application, the first mounting hole is disposed between two abutment grooves and is connected to the plug end.

[0010] In one embodiment of this application, one end of the second mounting hole is connected to the connecting portion, and the other end is connected to the outer periphery of the circuit board body.

[0011] In one embodiment of this application, the circuit board body has a connecting groove at one end away from the connecting block, the connecting groove is located between the plug-in part and the connecting part, and a connecting unit is provided in the connecting groove.

[0012] In one embodiment of this application, the mounting portion is provided with positioning posts relative to the circuit element. The positioning posts are connected to the periphery of the circuit element, and there are multiple positioning posts, each of which corresponds to a circuit element.

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] 1. The circuit board body has a plug-in part and a connecting part at both ends. The plug-in part and the connecting part have different structures, which can be used as a foolproof design to effectively prevent connection problems caused by incorrect orientation when installing the PCB board in the temple of the smart glasses. This ensures convenient and stable installation. The circuit board body has a first mounting hole and a second mounting hole respectively relative to the plug-in part and the connecting part. The first mounting hole and the second mounting hole, together with the plug-in part and the connecting part, make the circuit board body and the temple have multiple connection points with different structures, which can ensure the stability of the entire connection process.

Furthermore, these structures used to fix the circuit board body do not need to be too large in size, and most of them are connected to the outer periphery of the circuit board body, which allows for a large mounting area. This makes it easier to plan the installation positions of different circuit components, thereby achieving the goal of improving the product's high integration. Moreover, the highly integrated various circuit units allow the overall PCB board size to be reduced according to requirements, effectively improving the user experience.

[0016] 3. The PCB board adopts a 4-layer board structure. Connecting blocks protrude from the outer periphery of the circuit board body in the direction away from the PCB board. The operating structure of the circuit board body is a touch unit. The touch unit can be connected through the connecting blocks. Only one connecting block is required to connect the touch unit to the housing of the temple, which makes the smart glasses easy to control. In addition, there is only one component on the periphery of the PCB board of this application, which can have an anti-interference effect.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Reference Figures 1 to 2 To achieve the above objectives, this utility model proposes a PCB board for smart glasses, including a circuit board body 1. The circuit board body 1 has mounting portions 11 on both sides. Multiple circuit elements are arrayed on the mounting portions 11. One end of the circuit board body 1 has a plug-in portion 2 and the other end has a connecting portion 3. The mounting portion 11 has a first mounting hole 12 through the plug-in portion 2 and a second mounting hole 13 through the connecting portion 3.

[0025] A connecting block protrudes from the circuit board body 1, and a touch unit electrically connected to the circuit board body 1 is provided on the connecting block.

[0026] The circuit board body 1 has a plug-in part 2 and a connecting part 3 at both ends. The plug-in part 2 and the connecting part 3 have different structures, which can be used as a foolproof design to effectively prevent connection problems caused by incorrect orientation when installing the PCB board in the temple of the smart glasses. This ensures convenient and stable installation. The circuit board body 1 has a first mounting hole 12 and a second mounting hole 13 respectively relative to the plug-in part 2 and the connecting part 3. The first mounting hole 12 and the second mounting hole 13, together with the plug-in part 2 and the connecting part 3, make the circuit board body 1 and the temple have multiple connection points with different structures, which can ensure the stability of the entire connection process. The first mounting hole 12 and the second mounting hole 13 can also be used as positioning holes, which can effectively improve the installation speed of the circuit board body 1 and the overall structural strength after installation.

[0027] Both sides of the circuit board body 1 are mounting portions 11 for mounting different circuit components. Different circuit components are interconnected through the mounting portions 11. Utilizing the aforementioned mounting hole structure, plug-in portion 2, and connecting portion 3 structure, the entire circuit board body 1 can be quickly installed while ensuring its structural strength. Furthermore, these structures for fixing the circuit board body 1 do not need to be too large in size, and most of them are connected to the outer periphery of the circuit board body 1, which allows the mounting portion 11 to have a large area. This makes it easier to plan the installation positions of different circuit components, thereby achieving the goal of improving the product's high integration. Moreover, the highly integrated various circuit units allow the overall PCB board size to be reduced according to requirements, effectively improving the user experience.

[0028] The PCB board adopts a 4-layer board structure. Connecting blocks protrude from the outer periphery of the circuit board body 1 in the direction away from the PCB board. The operating structure of the circuit board body 1 is a touch unit. The touch unit can be connected through the connecting blocks. Only one connecting block is provided so that the touch unit can be connected to the housing of the temple, which makes the smart glasses easy to control. In addition, there is only one component on the periphery of the PCB board of this application, which can have an anti-interference effect. The control system inside the circuit board body 1 adopts a double-click anti-mistouch operation mode, which can effectively improve the user experience.

[0029] See also Figure 1 In one embodiment of this application, the plug-in portion 2 includes a plug-in end 21 and an abutment groove 22. At least two abutment grooves 22 are provided, and the two abutment grooves 22 are respectively connected to both sides of the plug-in end 21.

[0030] The abutment groove 22 is recessed on both sides of the circuit board body 1, and the abutment groove 22 is arc-shaped.

[0031] The plug-in part 2 is the main connection end of the circuit board body 1, which is used to ensure the stability of the entire circuit board connection. The plug-in end 21 is located at one end of the circuit board body 1 and is used to be inserted into the temple. Two arc-shaped abutment grooves 22 are respectively connected to the two sides of the plug-in end 21. When the mounting structure inside the temple is pressed against the abutment groove 22, it can wrap the entire plug-in end 21 inside. The inward arc-shaped abutment groove 22 can further make the connection of the entire circuit board body 1 more stable.

[0032] See also Figure 1 In one embodiment of this application, the first mounting hole 12 is provided between two abutment grooves 22, and the first mounting hole 12 is connected to the plug end 21.

[0033] The first mounting hole 12 is located between the two abutment grooves 22, so that when one end of the circuit board body 1 is installed in the smart glasses, the two abutment grooves 22 and the first mounting hole 12 cooperate with each other. Through the triangular fixing structure, the overall structural strength is guaranteed. Moreover, this structure is tightly fixed and occupies little space, which is conducive to the high integration of components on the PCB board.

[0034] See also Figure 1 In one embodiment of this application, one end of the second mounting hole 13 is connected to the connecting part 3, and the other end is connected to the outer periphery of the circuit board body 1.

[0035] The connecting part 3 is located on the outer periphery of one side of the circuit board body 1. The second mounting hole 13 is connected to the connecting part 3. The first mounting hole 12 and the second mounting hole 13 cooperate with each other to play a positioning role during installation, which can enable the PCB board to be quickly installed and removed. The second mounting hole 13 and the connecting part 3 cooperate with each other to quickly lock one side of the circuit board body 1. Furthermore, the first mounting hole 12 and the plug-in part 2, as well as the second mounting hole 13 and the connecting part 3 cooperate with each other to form a triangular positioning area, which can facilitate the reduction of the PCB board structure and make it easier to install and fix.

[0036] See also Figure 1 In one embodiment of this application, the circuit board body 1 is provided with a connecting groove 4 at one end away from the connecting block. The connecting groove 4 is located between the plug-in part 2 and the connecting part 3, and a connecting unit is provided in the connecting groove 4.

[0037] The connecting slot 4 is opened towards the inside of the circuit board body 1. It is located on the side of the circuit board body 1 away from the connecting block, so that the touch unit on the connecting block and the connecting unit in the connecting slot 4 can work stably. The connecting unit in the connecting slot 4 can be a connector for connecting peripherals, such as connecting to an external power source for charging. Moreover, the connecting unit is located in the connecting slot 4, so that the connecting unit can be protected inside the temple housing, which can prevent the connecting unit from being damaged.

[0038] See also Figure 1In one embodiment of this application, the mounting part 11 is provided with positioning posts 5 relative to the circuit element. The positioning posts 5 are connected to the periphery of the circuit element. There are multiple positioning posts 5, and each positioning post 5 corresponds to a circuit element.

[0039] There are multiple circuit components, among which the main control chip, such as the MCU, is more important and needs to be protected. Therefore, the temple housing is generally provided with a protective cavity. In order to enable the MCU to be quickly aligned and installed with the protective cavity, a positioning post 5 is provided next to the installation position of this important component. The positioning post 5 can enable the entire circuit board body 1 to be installed quickly and the important components to be quickly protected, which can effectively improve the installation and maintenance efficiency.
