Description

Technical Field

[0001] The utility model relates to the technical field of smart rings, in particular to a smart ring with a soft-hard combined circuit board. Background Art

[0002] A smart ring is a ring that integrates smart technology and is usually equipped with various sensors, processors, and connectivity functions. It can not only meet the needs of health monitoring and sports tracking, but also improve the user's quality of life and sense of fashion. The circuit board inside the smart ring is the core component of the smart ring function. The circuit board is responsible for the collection, processing, storage, and communication of sensor data, while providing functions such as user interface control and power management.

[0003] However, in existing smart rings, the size of the circuit board varies during the manufacturing process, and the circuit board needs to be bent when it is installed on the shell. The size of the bent circuit board does not match the size of the shell, which makes it difficult to fix the circuit board and the shell after installation or causes unstable installation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a smart ring with a hard-soft combined circuit board, which can solve the problem in the prior smart ring that the size of the circuit board after bending does not match the size of the outer shell, making it difficult to fix the circuit board and the outer shell after installation. The hard board and the soft board can be used in combination to be better bent at a specified position so that the circuit board can be stably attached to the inner wall of the ring. At the same time, the concave-convex structure on the edge of the circuit board increases the gap for glue passing during post-process injection molding, thereby ensuring sealing and reliably protecting electronic devices.

[0005] To achieve the above object, the utility model provides the following technical solution: a smart ring with a hard-soft circuit board, comprising a shell, a colloid-filled body is arranged inside the shell, a battery cell is arranged inside the colloid-filled body, a circuit board assembly is arranged on one side of the battery cell, the circuit board assembly comprises a hard board and a soft board, and electronic components are installed on the outer surface of the hard board;

[0006] Notches are provided at both ends of the connection between the hard board and the soft board, and bosses are provided on the upper and lower sides of the hard board respectively.

[0007] Through the above technical solution, the notch concentrates the bending stress, which allows for better limited assembly, the boss can be effectively fixed, and the gap for subsequent injection molding can be increased, thereby ensuring sealing and reliably protecting electronic devices.

[0008] Furthermore, multiple hard boards and multiple soft boards are provided, and the heights of the hard boards are all consistent, and the heights of the soft boards are all consistent.

[0009] Through the above technical solution, the consistency of the circuit board height is ensured and the adaptability of the circuit board to the shell size is improved.

[0010] Furthermore, the hard board and the soft board are arranged alternately, and the length of the hard board is greater than the length of the soft board.

[0011] Through the above technical solution, the hard board can ensure that the electronic components are firmly and reliably fixed, while the setting of the soft board allows the circuit board to be bent at a specified position, so that the circuit board can be stably attached to the inner wall of the ring.

[0012] Furthermore, a positioning assembly is connected to one side of the hard plate, and the positioning assembly includes a fixing block, a clamping plate and a thin plate. A clamping slot is provided inside the fixing block, and the clamping plate is symmetrically distributed about the longitudinal center line of the thin plate.

[0013] Through the above technical solution, the positioning component can position the two hard boards connected to the flexible board after bending, thereby ensuring the consistency of the bending angles of each circuit board of the same size, and ensuring the consistency of the internal circuit boards of the smart ring of the same size and the installation position of the outer shell.

[0014] Furthermore, the card slots are distributed at equal angles with respect to the center of the fixed block, and the connection between the card plate and the card slots is a snap-fit ​​connection.

[0015] Through the above technical solution, after the card plate is engaged with the card slot, the hard board connected to the fixing block is positioned. At this time, the soft board between the two hard boards cannot be bent further, thereby ensuring the consistency of the bending curvature of each circuit board of the same size.

[0016] Furthermore, one side of the thin plate is connected to an adjustment component, which includes a slider, an adjustment block and a positioning plate. The slider is connected to the thin plate by a sliding connection, and the positioning plate is symmetrically distributed about the longitudinal center line of the adjustment block.

[0017] Through the above technical solution, the adjustment component can adjust the structure of the positioning component, so that after the bending angle of the soft board changes, the positioning component is still suitable for the positioning requirements of the two hard boards connected by the soft board.

[0018] Furthermore, a spring is arranged inside the thin plate, and the other end of the spring is connected to the clamping plate.

[0019] Through the above technical solution, the spring can push the card plate to fit tightly with the card slot.

[0020] Furthermore, the thickness of the positioning plate is greater than that of the card plate, and positioning grooves are provided at equal intervals inside the card plate, and the positioning plate and the positioning grooves are connected by a snap-fit ​​connection.

[0021] Through the above technical solution, the card plate can slide inside the thin plate, and the card plate can be positioned by the snap connection between the positioning plate and the positioning groove. The positioning position of the positioning component on the hard plate can be changed by adjusting the relative position of the card plate and the thin plate.

[0022] Compared with the prior art, the utility model provides a smart ring with a soft-hard combined circuit board, which has the following beneficial effects:

[0023] In the utility model, the hard board can ensure that the electronic components are firmly and reliably fixed, and the setting of the soft board allows the circuit board to be bent at a specified position, which is convenient for the circuit board to be stably attached to the inner ring wall of the ring, thereby ensuring the consistency of the position of the circuit board components in the assembled product. The boss can be effectively fixed and can increase the gap for post-process injection molding to ensure sealing, which can reliably protect the electronic components, thereby greatly reducing the difficulty of assembly and improving the production efficiency and yield rate of the smart ring.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0034] See also Figure 1-Figure 3 The utility model provides a technical solution: a smart ring with a hard-soft circuit board, comprising a shell 1, a colloid-filled body 2 is arranged inside the shell 1, a battery cell 3 is arranged inside the colloid-filled body 2, a circuit board assembly is arranged on one side of the battery cell 3, the circuit board assembly comprises a hard board 4 and a soft board 5, and an electronic component 6 is installed on the outer surface of the hard board 4;

[0035] See also Figure 1-Figure 3 Notches 7 are provided at both ends of the connection between the hard board 4 and the soft board 5, and bosses 8 are provided on the upper and lower sides of the hard board 4 respectively.

[0036] It should be noted that the notch 7 concentrates the bending stress, which allows for better limited assembly. The boss 8 can be effectively fixed and can increase the gap for subsequent injection molding, thereby ensuring sealing and reliably protecting electronic devices.

[0037] See also Figure 1-Figure 3 Multiple hard boards 4 and soft boards 5 are provided, the heights of the hard boards 4 are consistent, the heights of the soft boards 5 are consistent, the hard boards 4 and the soft boards 5 are staggered, and the length of the hard boards 4 is greater than the length of the soft boards 5.

[0038] The functions of the hard board 4 and the soft board 5 are as follows: the hard board 4 can ensure that the electronic components 6 are firmly and reliably fixed, while the setting of the soft board 5 allows the circuit board to be bent at a specified position, making it easier for the circuit board to be stably attached to the inner wall of the ring, thereby ensuring the consistency of the position of the circuit board components in the assembled product. Example 1

[0039] The difference between this embodiment and embodiment 1 is that, please refer to Figure 3-Figure 5 A positioning assembly is connected to one side of the hard plate 4, and the positioning assembly includes a fixing block 9, a clamping plate 11 and a thin plate 14. A clamping slot 10 is opened inside the fixing block 9, and the clamping plate 11 is symmetrically distributed about the longitudinal center line of the thin plate 14.

[0040] It is worth mentioning that the positioning component can position the two hard boards 4 connected to the bent soft board 5, thereby ensuring the consistency of the bending angle of the same soft board 5 in each circuit board of the same size, and ensuring the consistency of the internal circuit board of the smart ring of the same size and the installation position of the outer shell 1.

[0041] See also Figure 3-Figure 5 The card slots 10 are distributed at equal angles with respect to the center of the fixing block 9, and the connection between the card plate 11 and the card slots 10 is a snap-fit ​​connection.

[0042] The principle of positioning the hard board 4 is: after the soft board 5 is bent, the two hard boards 4 connected by the soft board 5 will be at an angle, and then the card boards 11 on both sides of the thin plate 14 are respectively inserted into the card slots 10 opened inside the fixed block 9. After the card boards 11 are engaged and connected with the card slots 10, the hard board 4 connected to the fixed block 9 is positioned. At this time, the soft board 5 between the two hard boards 4 cannot be bent further, thereby ensuring the consistency of the bending angle of the same soft board 5 in the same size of circuit boards, which is conducive to ensuring the consistency of the overall bending curvature of the same size of circuit boards. Example 2

[0043] The difference between this embodiment and embodiment 2 is that, please refer to Figure 3-Figure 8 One side of the thin plate 14 is connected to an adjustment component, which includes a slider 15, an adjustment block 16 and a positioning plate 17. The slider 15 is connected to the thin plate 14 by sliding connection. The positioning plate 17 is symmetrically distributed about the longitudinal center line of the adjustment block 16. A spring 13 is arranged inside the thin plate 14, and the other end of the spring 13 is interconnected with the card plate 11.

[0044] It is worth mentioning that the adjustment component can adjust the structure of the positioning component, so that after the bending angle of the soft board 5 changes, the positioning component is still suitable for the positioning requirements of the two hard boards 4 connected by the soft board 5.

[0045] See also Figure 3-Figure 8 The thickness of the positioning plate 17 is greater than that of the card plate 11. The card plate 11 has positioning grooves 12 formed at equal distances inside. The positioning plate 17 is connected to the positioning grooves 12 by a snap-fit ​​connection.

[0046] The principle of the structure of the adjustable positioning component is: when the size of the shell 1 of the smart ring changes, the overall bending curvature of the circuit board connected inside it will also change accordingly, so the bending angle of the soft board 5 will also change, and the positions of the two hard boards 4 connected to the soft board 5 will also change. If the hard board 4 is to be positioned, first bend the soft board 5 to a suitable angle, and the two hard boards 4 connected to the soft board 5 will still be at a certain angle, then pull the adjustment block 16 to separate the positioning plate 17 connected to the adjustment block 16 from the card plate 11, and then the spring 13 pushes the card plate 11 to slide to the outside of the thin plate 14. At this time, the relative position of the card plate 11 and the thin plate 14 changes, and then the card plates 11 on both sides of the thin plate 14 are respectively inserted into the card slots 10 opened inside the fixing block 9. After the card plate 11 is engaged with the card slot 10, the adjustment block 16 is pushed toward the inside of the thin plate 14, so that the positioning plate 17 is engaged with the positioning slot 12 and the card plate 11 is positioned, and at this time the hard board 4 is positioned.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
