Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of TWS Bluetooth headset charging boxes, and in particular to a TWS Bluetooth headset charging box with an FPC passing through a rotating shaft mechanism. Background Art
[0002] Currently, TWS Bluetooth earphones are popular among users due to their freedom from wires and easy storage. To extend the battery life of TWS Bluetooth earphones, they are usually equipped with a charging box. When the user is not using the TWS Bluetooth earphones, the TWS Bluetooth earphones can be stored in the charging box.
[0003] In the prior art, referring to Chinese patent document CN113972719A, a TWS Bluetooth headset charging box is usually composed of a box body and a cover body, which are in the form of a flip-up structure. The TWS Bluetooth headset is placed in the box body, and a battery and a PCB board for powering the headset are provided in the box body to charge the headset. This type of charging box is relatively traditional and cannot bring a more novel box opening experience to consumers. Chinese patent document CN110881154A discloses an earphone charging box, comprising a first box body and a second box body, wherein a first receiving groove for placing a first earphone is provided in the first box body, and a second receiving groove for placing a second earphone is provided in the second box body; the first box body is rotatably connected to the second box body; when the first receiving groove and the second receiving groove are close to each other, the charging box is closed; when the first receiving groove and the second receiving groove are away from each other, the charging box is opened. At the same time, the patent also discloses the following technical features: a third charging contact is provided on the first top surface of the charging box, and a fourth charging contact is provided on the second top surface. When the charging box is closed, the first top surface and the second top surface are close to each other, and the third charging contact is electrically contacted with the fourth charging contact; through the electrical contact between the third charging contact and the fourth charging contact, the first box body and the second box body are both energized to realize charging of the earphones.
[0004] However, the earphone charging box disclosed in the above-mentioned patent document CN110881154A has the following technical problems: First, the third charging contact and the fourth charging contact are exposed to the outside and are bound to be affected by the outside air or water vapor, causing oxidation of the contact surface or entry of water vapor to affect the electrical performance; second, the electrical contact of the third charging contact and the fourth charging contact is easily affected by the closure of the first box body and the second box body. If the first box body and the second box body are not closed tightly or the position is slightly offset, it is easy to cause poor contact between the third charging contact and the fourth charging contact; third, during the electrical contact process, the third charging contact and the fourth charging contact must adopt an elastic contact method to improve the success rate of electrical contact. The elastic contact method requires at least one of the third charging contact and the fourth charging contact to adopt a spring-type contact head. However, the spring-type contact head will protrude outward, which not only increases the structural complexity, but also easily causes a gap to form between the first top surface of the first box body and the second top surface of the second box body, affecting the overall performance of the charging box. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a TWS Bluetooth headset charging box with an FPC passing through a hinge mechanism based on the above-mentioned deficiencies in the prior art. A hinge mechanism is installed between the first box body and the second box body of the headset charging box, and a charging control board is installed inside the first box body. The other end of the charging control board is connected to the first FPC flexible circuit board and the second FPC flexible circuit board. An FPC through hole is opened in the middle of the shaft sleeve of the hinge mechanism. After the second FPC flexible circuit board passes through the FPC through hole of the shaft sleeve, it enters the second box body to charge the TWS Bluetooth headset in the second box body; the way in which the FPC passes through the hinge mechanism can avoid the problems of contact oxidation and poor contact in the prior art.

[0026] The structural principle and working principle of the present invention are further described in detail below with reference to the accompanying drawings.
[0027] like Figures 1-9As shown, the present invention is a TWS Bluetooth headset charging box with an FPC passing through a hinge mechanism, comprising a first box body 100, a second box body 200 and a hinge mechanism 300; the first box body 100 is provided with a first accommodating cavity 101 for accommodating a TWS Bluetooth headset 400, and the second box body 200 is provided with a second accommodating cavity 201 for accommodating another TWS Bluetooth headset 400; the hinge mechanism 300 is installed between the first box body 100 and the second box body 200, and the first box body 100 and the second box body 200 can be rotated to cover or open each other based on the hinge mechanism 300; a charging control board 6 is installed in the first box body 100, one end of the charging control board 6 is provided with a charging interface 61, and the other end of the charging control board 6 is connected to the first F PC flexible circuit board 62 and second FPC flexible circuit board 63; the first FPC flexible circuit board 62 is connected to the first charging pin 621, which extends into the first accommodating cavity 101 and is used to charge the TWS Bluetooth headset 400 in the first accommodating cavity 101; the hinge mechanism 300 includes a sleeve 1, and an FPC through hole 15 is opened in the middle of the sleeve 1. After the second FPC flexible circuit board 63 passes through the FPC through hole 15 of the sleeve 1, it enters the second box body 200. The second FPC flexible circuit board 63 is connected to the second charging pin 631, which extends into the second accommodating cavity 201 and is used to charge the TWS Bluetooth headset 400 in the second accommodating cavity 201. When charging the TWS Bluetooth headset 400, the charging control board 6 charges the TWS Bluetooth headset 400 in the first accommodating cavity 101 via the first FPC flexible circuit board 62 and the first charging pin 621, and the charging control board 6 charges the TWS Bluetooth headset 400 in the second accommodating cavity 201 via the second FPC flexible circuit board 63 and the second charging pin 631. The method of passing the FPC through the hinge mechanism of the present invention can avoid the problems of contact oxidation and poor contact in the prior art. At the same time, the structure is relatively simple, does not affect the covering of the first box body 100 and the second box body 200, and does not affect the overall structure and electrical performance of the first box body 100 and the second box body 200.
[0028] like Figure 5-Figure 8The first housing 100 is shown with a first light guide 104 at the end opposite the hinge mechanism. The first flexible printed circuit board 62 extends to the rear end of the first light guide 104 and is equipped with several LED lights 622 corresponding to the first light guide 104. The second housing 200 is shown with a second light guide 204 at the end opposite the hinge mechanism. The second flexible printed circuit board 63 extends to the rear end of the second light guide 204 and is equipped with several LED lights 632 corresponding to the second light guide 204. There are three LED lights 622 and three LED lights 632, each of which serves as a charging indicator.
[0029] like Figure 3-Figure 7 、 Figure 9As shown, the shaft sleeve 1 of the rotating shaft mechanism 300 is provided with a first shaft hole 11 and a second shaft hole 12 in parallel; a first rotating shaft 13 is installed in the first shaft hole 11, and the outer end of the first rotating shaft 13 extends out of the first shaft hole 11; a second rotating shaft 14 is installed in the second shaft hole 12, and the outer end of the second rotating shaft 14 extends out of the second shaft hole 12; one end of the first box body 100 is provided with a first shaft seat 102, and both side walls of the first shaft seat 102 are respectively provided with first connecting holes 103, and the outer end of the first rotating shaft 13 can be rotatably inserted into the corresponding first connecting hole 103; one end of the second box body 200 is provided with a second shaft seat 202, and both side walls of the second shaft seat 202 are respectively provided with second connecting holes 203, and the outer end of the second rotating shaft 14 can be rotatably inserted into the corresponding second connecting hole 203. The present invention installs a rotating shaft mechanism 300 between the first box body 100 and one end of the second box body 200. Since the rotating shaft mechanism 300 includes a shaft sleeve 1, the shaft sleeve 1 is provided with a first shaft hole 11 and a second shaft hole 12 in parallel, the first shaft hole 11 is installed with a first rotating shaft 13, and the second shaft hole 12 is installed with a second rotating shaft 14. Therefore, after the first rotating shaft is inserted into the first connecting hole 103 of the first box body, the first box body 100 can rotate based on the first rotating shaft 13, and after the second rotating shaft 14 is inserted into the second connecting hole 203 of the second box body 200, the second box body 200 can rotate based on the second rotating shaft 14. Moreover, since the distance between the first shaft hole 11 and the second shaft hole 12 is set according to product requirements, the shaft sleeve 1 as a whole is The first box body 100 is flat, so when it rotates on the first shaft 13, it is not easily interfered with by the second box body 200 and the second shaft 14, and when the second box body 200 rotates on the second shaft 14, it is also not easily interfered with by the first box body 100 and the first shaft 13. Therefore, when the first box body 100 and the second box body 200 rotate to cover or open each other based on the shaft mechanism 300, it can ensure that after the first box body 100 and the second box body 200 are covered, no long cylindrical protrusion protruding outward is formed at the position of the shaft, and it can also ensure that after the first box body 100 and the second box body 200 are opened, the rotation opening angle can be greater than or equal to 180 degrees, so as to facilitate the removal or placement of the TWS Bluetooth headset 400.
[0030] like Figure 3-Figure 7 、 Figure 9 As shown, there are two first axial holes 11 and two second axial holes 12, one of which is arranged side by side at one end of the sleeve 1, and the other is arranged side by side at one end of the sleeve. A first rotating shaft 13 is installed in each of the two first axial holes 11, and a second rotating shaft 14 is installed in each of the two second axial holes 12. The purpose of providing two first axial holes 11 and second axial holes 12 is to prevent the first rotating shaft 13 and the second rotating shaft 14 from passing through the middle of the sleeve 1, and to open the FPC through hole 15 in the middle of the sleeve 1.
[0031] like Figure 6 and Figure 7 As shown, the first box body 100 includes a first outer shell 2 and a first receiving body 3. The first receiving body 3 is installed in the first outer shell 2, and the first receiving cavity 101 is provided above the first receiving body 3. The second box body 200 includes a second outer shell 4 and a second receiving body 5. The second receiving body 5 is installed in the second outer shell 4, and the second receiving cavity 201 is provided above the second receiving body 5. The first shaft seat 102 is provided at one end of the first outer shell 2, and the second shaft seat 202 is provided at one end of the second outer shell 4.
[0032] like Figure 6 and Figure 7 As shown, the first outer shell 2 is provided with a plurality of first clamping blocks 21 at intervals on the inner side of its edge, and the first storage body 3 is provided with a plurality of first clamping slots 31 at intervals on the outer side of its edge. The first clamping blocks 21 engage with the corresponding first clamping slots 31. The second outer shell 4 is provided with a plurality of second clamping blocks 41 at intervals on the inner side of its edge, and the second storage body 5 is provided with a plurality of second clamping slots 51 at intervals on the outer side of its edge. The second clamping blocks 41 engage with the corresponding second clamping slots 51. This clamping method does not require screw assembly and ensures a good clamping and stability between the first outer shell 2 and the first storage body 3, forming a whole. It also ensures a good clamping and stability between the second outer shell 4 and the second storage body 5, forming a whole.
[0033] like Figure 6 and Figure 7 As shown, at least one first magnet 32 is disposed within the end of the first storage body 3 opposite to the direction of the rotating shaft mechanism, and at least one second magnet 52 is disposed within the end of the second storage body 5 opposite to the direction of the rotating shaft mechanism. When the first box body 100 and the second box body 200 are covered with each other, the first magnet 32 and the corresponding second magnet 52 are magnetically attracted to each other. In this embodiment, two first magnets 32 and two second magnets 52 are symmetrically disposed. When the first box body 100 and the second box body 200 are covered with each other, one set of the first magnets 32 and the second magnets 52 are magnetically attracted to each other, and the other set of the first magnets 32 and the second magnets 52 are also magnetically attracted to each other, so that the first box body 100 and the second box body 200 are stably covered together. When the first box body 100 and the second box body 200 need to be opened, a slight force is applied to overcome the magnetic attraction and the first box body 100 and the second box body 200 can be opened.
[0034] like Figure 3-Figure 7As shown, the second housing 200 is further provided with a third accommodating cavity 205 for accommodating a Bluetooth transmitter (not shown). The third accommodating cavity 205 is provided above the second storage body 5. A Bluetooth transmitter is a Bluetooth device compatible with smart devices such as smartphones, tablets, laptops, desktop computers, and smart screens. The Bluetooth transmitter typically has a USB Type-A port, a USB Type-C port, or the Lightning Dock port of an iPhone. After the Bluetooth transmitter is plugged into the smart device, the smart device can establish a Bluetooth connection with the TWS Bluetooth headset through the Bluetooth transmitter. Because the Bluetooth modules built into smart devices such as mobile phones and tablets often experience high latency, high distortion, and slow transmission speeds when connected to TWS Bluetooth headsets, plugging the smart device into the Bluetooth transmitter enables signal transmission between the smart device and the TWS Bluetooth headset to achieve low latency, low distortion, and fast transmission speeds. Therefore, some headphone users (especially gamers and music enthusiasts) often plug a Bluetooth transmitter into their smart devices while using TWS Bluetooth headsets. The present invention provides a third accommodating cavity 205 for accommodating the Bluetooth transmitter within the second box body 200, which enables the TWS Bluetooth headset charging box to accommodate the Bluetooth transmitter and the TWS Bluetooth headset at the same time, making it very convenient to use.
[0035] like Figure 3-Figure 7 As shown, the first accommodating cavity 101 and the second accommodating cavity 201 are respectively adapted to the shape of the TWS Bluetooth headset 400, and the third accommodating cavity 205 is adapted to the shape of the Bluetooth transmitter.
