Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a magnetic shielding structure that solves the problem of magnetic back clips affecting the performance of wearable terminals. Background Technology

[0002] Currently, there are many types of clips for wearable devices on the market, and magnetic clips are widely accepted as one of them, mainly because they are easy to install and have wide applicability. The principle of a magnetic clip is that the magnet in the clip cover attracts the magnet inside the wearable device, clamping the clothing between them to achieve the purpose of wearing. This necessitates that the magnetic force must be strong enough to overcome the weight of the device while also ensuring that it does not easily fall off during human movement.

[0003] However, the impact of strong magnetism on the communication performance of wearable devices has been largely overlooked. This is mainly because the impact of strong magnetism on wearable devices is primarily reflected in the performance of the device's antenna. For general high-frequency antennas, their anti-interference performance is very strong, and the impact of static magnetic interference is almost negligible. However, for some low-frequency antennas, the antenna anti-interference performance is not very strong, and they are easily affected by static magnetic interference, especially during long-distance communication where the interference phenomenon is obvious.

[0004] Currently available magnetic back clips for wearable devices generally have strong magnetic attraction and high reliability. However, some wearable devices with low-frequency antennas are susceptible to strong magnetic interference, which can affect their communication performance, especially during long-distance communication, where the impact on signal delay is more pronounced. Therefore, if magnetic back clips are used for such devices, necessary magnetic shielding design must be considered. Summary of the Invention

[0005] The main objective of this invention is to provide a magnetic shielding structure that addresses the impact of magnetic back clips on the inherent performance of wearable devices, effectively solving the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A magnetic shielding structure for addressing the impact of magnetic back clips on the inherent performance of wearable devices includes a magnetic base and a magnetic clip cover, and further includes:

[0008] A fixing component is installed on the upper part of the magnetic base near the magnetic clip cover, for further fixing the magnetic base and the magnetic clip cover to the clothing;

[0009] A back cover is installed on the back of a magnetic clip cover. The magnetic clip cover has a first receiving compartment in the middle, and the magnetic base has a second receiving compartment in the middle.

[0010] Eight magnetic shielding mechanisms are arranged symmetrically in the first and second accommodating compartments, with four of the eight magnetic shielding mechanisms forming a group.

[0011] Each of the aforementioned magnetic shielding mechanisms consists of magnets, foam, and magnetic shielding covers. The aforementioned magnetic shielding covers are divided into upper and lower groups, which are rectangularly distributed in the first and second accommodating chambers, respectively. The aforementioned magnets and foam are respectively disposed inside the aforementioned magnetic shielding covers. The aforementioned foams are all connected to the inner wall of the magnetic shielding cover on the same side, and the aforementioned magnets are all connected to the foam on the same side.

[0012] Preferably, the four magnets located on the upper and lower sides have opposite magnetic properties.

[0013] Preferably, the fixing component includes:

[0014] The mounting block is installed on the upper back of the second accommodating compartment. The mounting block has a sliding hole on its left side and a clothing accommodating slot on its right side.

[0015] A puncture mechanism is disposed inside a sliding hole, and a circular hole is provided on the right side of the inner cavity of the sliding hole.

[0016] A raised mechanism is installed on the upper front side of the magnetic clip cover and is adapted to the clothing receiving slot;

[0017] Two fixing clips are provided, both of which are located at the rear of the mounting block and on the left and right sides of the sliding hole.

[0018] Preferably, the puncture mechanism includes:

[0019] The handle is disposed in the inner cavity of the sliding hole, and a groove adapted to the fixing clip is provided on the rear side of the middle part of the handle;

[0020] The pusher is located on the right side of the handle.

[0021] Preferably, the size of the circular hole is the same as that of the pusher pin.

[0022] Preferably, the device further includes a terminal device, which is integrated with the magnetic base, and the terminal device has an antenna on its top.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention symmetrically arranges a magnetic shielding mechanism with a magnetic shielding cover inside the receiving chamber of the magnetic clip and the magnetic base. The cylindrical magnetic shielding cover forms a nearly fully enclosed shielding space, concentrating the magnetic field generated by the magnet inside and greatly reducing the outward diffusion of the magnetic field. At the same time, combined with the foam isolation design between the magnet and the shielding cover, it avoids the magnetic field from being conducted through direct contact and ensures structural stability. Ultimately, it reduces the magnetic flux density at the low-frequency antenna of the terminal device to below the interference threshold, ensuring that the wearable terminal can maintain stable communication performance during long-distance communication.

[0025] 2. This invention first uses a design of four symmetrically distributed magnets in a group, combined with the magnetic shielding effect, to significantly enhance the magnetic attraction between the magnets and greatly improve the stability of wearing the garment. Then, by adding a fixing component consisting of a piercing mechanism and a protrusion mechanism, the device is further prevented from shifting or falling off during vigorous human activity by mechanically fixing the garment by pushing the needle to pierce it and engaging with the fixing clip, based on the magnetic clamping of the garment.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Example 1, as Figure 1 - Figure 10 As shown, a magnetic shielding structure for addressing the impact of magnetic back clips on the inherent performance of wearable devices includes a magnetic base 1 and a magnetic clip cover 2, and further includes:

[0039] Fixing component 3 is installed on the upper part of the magnetic base 1 near the magnetic clip 2;

[0040] Back cover 6 is installed on the back of magnetic clip cover 2. The magnetic clip cover 2 has a first receiving compartment 4 in the middle and the magnetic base 1 has a second receiving compartment 7 in the middle.

[0041] Eight magnetic shielding mechanisms 5 are arranged in groups of four, symmetrically in the first accommodating chamber 4 and the second accommodating chamber 7, respectively.

[0042] Each of the several magnetic shielding mechanisms 5 consists of magnets 51, foam 52 and magnetic shielding covers 53. The magnetic shielding covers 53 are divided into upper and lower groups, which are rectangularly distributed in the first accommodating chamber 4 and the second accommodating chamber 7, respectively. The magnets 51 and foam 52 are respectively arranged in the magnetic shielding covers 53. The foam 52 is connected to the inner wall of the magnetic shielding cover 53 on the same side, and the magnets 51 are connected to the foam 52 on the same side.

[0043] The installation method of the magnetic shielding mechanism 5 described above is as follows:

[0044] Foam 52 is attached to the inner wall of magnetic shielding cover 53, and then magnet 51 is embedded in magnetic shielding cover 53 so that magnet 51 and foam 52 are tightly attached. Finally, the eight assembled magnetic shielding mechanisms 5 are divided into two groups of four, which are rectangularly distributed and fixed in the first and second accommodating chambers 4 and 7 respectively, ensuring that the magnets 51 in the upper and lower groups have opposite magnetism and are symmetrical in position.

[0045] The design of four sets of magnets 51 evenly and symmetrically distributed ensures uniform magnetic attraction force.

[0046] Specifically, during implementation, the staff first place the clothing between the magnetic base 1 and the magnetic clip 2. The two sets of magnetic shielding mechanisms 5 attract each other, causing the magnetic base 1 and the magnetic clip 2 to adhere together, clamping the clothing in the middle. Then, the staff manually pushes the fixing component 3 to pass through the clothing, thereby further improving the reliability of wearing.

[0047] Furthermore, as described above, the magnetic shield 53 is designed as a cylindrical structure, forming a nearly fully enclosed shield, so that the magnetic field generated by the magnet 51 is mainly concentrated inside, reducing the outward diffusion of the magnetic field. The magnetic shield 53 and the magnet 51 are separated by foam 52 to avoid direct friction between the magnet 51 and the shield, and it can also play a buffering role.

[0048] The composition and implementation principle of fixed component 3 are as follows:

[0049] Fixed component 3 includes:

[0050] Mounting block 31 is installed on the upper back of the second accommodating compartment 7. Mounting block 31 has a sliding hole on the left side and a clothing accommodating slot 34 on the right side.

[0051] The puncture mechanism 32 is installed inside the sliding hole, and a circular hole is provided on the right side of the inner cavity of the sliding hole.

[0052] The protruding mechanism 35 is installed on the upper front side of the magnetic clamp cover 2 and is adapted to the clothing receiving slot 34. When the staff places the magnetic base 1 and the magnetic clamp cover 2 on the inside and outside of the clothing, the protruding mechanism 35 can push the clothing into the clothing receiving slot 34 to achieve initial positioning.

[0053] Two fixing clips 33 are provided at the rear of the mounting block 31 and on the left and right sides of the sliding hole to restrict the position of the puncture mechanism 32.

[0054] The puncture mechanism 32 is specifically composed of:

[0055] The handle 321 is set in the inner cavity of the sliding hole. A groove 322 adapted to the fixing clip 33 is opened on the rear side of the middle part of the handle 321. The handle 321 is fixed by the engagement of the groove 322 with the fixing clip 33.

[0056] Push pin 323 is located on the right side of the handle 321. The size of the circular hole is the same as that of push pin 323. Push pin 323 can pass through the circular hole and insert into the clothing to further enhance the fixing effect.

[0057] Specifically, after the magnetic base 1 and magnetic clip 2 are attracted by the magnetic shielding mechanism 5, the protrusion mechanism 35 pushes the clothes into the clothes receiving slot 34 to achieve the initial positioning of the clothes. Then, the staff manually pushes the handle 321 so that the push pin 323 passes through the circular hole and through the clothes. At the same time, the groove 322 will engage with the fixing clip 33 to complete the overall fixation, thus forming a mechanical fixation to prevent the device from shifting or falling off during vigorous activities.

[0058] Furthermore, the device also includes a terminal device 8, which is integrated with the magnetic base 1. The terminal device 8 has a 900MFPC antenna 9 on its top. The magnetic shielding mechanism 5 is symmetrically arranged in the first and second housing chambers 4 and 7, forming a targeted shielding layout with the antenna 9 on the top of the terminal device 8. The insulation design of the foam 52 not only avoids the magnetic field from being conducted through direct contact, but also ensures the stability of the shielding structure. Ultimately, the magnetic field strength at the 900MFPC antenna 9 is reduced to below the interference threshold, ensuring that the communication performance of the low-frequency 900MFPC antenna 9 is not affected.

[0059] Example 2: This example tests and verifies the performance of the magnetic shielding structure under the following conditions: In an open environment, using the same wearable terminal equipped with a 900MFPC antenna 9, the device is switched between three states: no magnetic back clip, magnetic back clip without magnetic shielding, and magnetic back clip with both magnetic and magnetic shielding. Connecting to another mobile workstation, at distances of 1.2km and 800 meters, the mobile workstation sends approximately 200 ping packets of 1450 bytes of data to the wearable terminal, recording the packet loss rate and latency. Simultaneously, magnetic simulation software is used to test the magnetic attraction force and magnetic flux density modulus at the antenna under the three states.

[0060] 1. Communication performance test results:

[0061] Back clip type 1.2km packet loss rate 1.2km delay Packet loss rate over 800 meters 800-meter delay Non-magnetic back clip 0% 24ms 0% 13ms Magnetic and non-magnetic shielded back clip 0% 30ms 0% 21ms Magnetic back clip with magnetic shielding 0% 25ms 0% 14ms

[0062] 2. Magnetic property simulation test results:

[0063] Test Project Non-magnetic back clip Magnetic and non-magnetic shielded back clip Magnetic back clip with magnetic shielding Magnetic forceN 2.7801E-6 46.218 179.65 The magnetic flux density mode T at the antenna 9.1829E-5 3.6707E-4 8.6499E-5

[0064] The test results show that:

[0065] In terms of communication performance, after installing the magnetic shielding structure of this solution, the latency of wearable terminals during long-distance communication is significantly reduced, approaching the state of no magnetic back clip, and completely solving the problem of strong magnetic interference to low-frequency antennas.

[0066] In terms of magnetic performance, the magnetic shielding structure increases the mutual attraction force of magnet 51 from 46.218N to 179.65N, significantly improving wearability reliability; at the same time, the magnetic flux density mode at antenna 9 decreases from 3.6707E-4T to 8.6499E-5T, which is lower than the state without magnetic back clip, effectively shielding against magnetic field interference.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
