Description

Technical Field

[0001] This invention belongs to the field of charging device technology, and particularly relates to a wireless charging device for Bluetooth headsets. Background Technology

[0002] As mentioned in patent application CN202021909819.7, the rechargeable battery inside the existing Bluetooth headset wireless charging device is generally fixed inside the charging device and cannot be removed. As a result, when the rechargeable battery is depleted, the user must recharge the battery in order to continue using the Bluetooth headset, which affects the normal use of the Bluetooth headset.

[0003] The solution is to install a detachable cover at the bottom of the charging device casing. When the rechargeable battery is depleted, the user can open the cover by pressing the movable buckle to replace the internal rechargeable battery.

[0004] However, due to the high precision requirements of rechargeable batteries, the use of movable clips is easily limited by the frequency and intensity of use. It is difficult to achieve a complete seal when installing and removing batteries using clips, which affects the normal use of Bluetooth headsets. Summary of the Invention

[0005] This invention addresses the problem in existing technologies where the high precision requirements of rechargeable batteries limit the use of movable clips due to frequency and intensity constraints, making it difficult to achieve a completely tight seal when installing and removing batteries, thus affecting the normal use of Bluetooth headsets. The invention proposes the following technical solution: a wireless charging device for Bluetooth headsets, comprising a housing, a cover movably mounted on the upper end of the housing, a battery compartment at the lower end of the housing, cavities on both sides of the battery compartment, a first magnetic block within each cavity, a rechargeable battery within the battery compartment, a connecting cover fixedly connected to the lower end of the rechargeable battery (the bottom color of the connecting cover is the same as the bottom color of the housing), second magnetic blocks at both ends of the rechargeable battery, with each of the two first magnetic blocks engaging with an adjacent second magnetic block, and an earphone ejection mechanism and a battery ejection mechanism located above the battery compartment.

[0006] As a preferred embodiment of the above technical solution, the rechargeable battery has two battery interfaces at its upper end, and each of the two battery interfaces has a connector at its upper end.

[0007] As a preferred embodiment of the above technical solution, the front side of the casing is provided with multiple speaker holes, and the first display screen and the second display screen are arranged sequentially from top to bottom on the right side of the multiple speaker holes.

[0008] As a preferred embodiment of the above technical solution, the first display screen is used to view the time and the battery level of the casing, the second display screen is used to view the remaining battery level of the rechargeable battery, the lower end of the second display screen is provided with a charging port, and the right side of the charging port is provided with a power switch.

[0009] As a preferred embodiment of the above technical solution, the earphone pop-out mechanism includes a slide groove formed inside the housing, the slide groove being located above the battery compartment, and mounting slots being provided above and below the slide groove. A first electromagnet is installed in the upper mounting slot, and a second electromagnet is installed in the lower mounting slot.

[0010] As a preferred embodiment of the above technical solution, a magnetic piston plate is slidably connected between the left and right inner walls of the slide. Two rectangular cavities are opened above the slide. Two first push rods are fixedly connected to the upper end of the magnetic piston plate. The upper ends of the two first push rods extend through the inner top of the slide and into the rectangular cavity. The upper end of the magnetic piston plate is elastically connected to the inner top of the slide through two first restoring springs.

[0011] As a preferred embodiment of the above technical solution, the battery ejection mechanism includes two second push rods fixedly connected to the lower end of the magnetic piston plate. The lower ends of the two second push rods extend through the inner bottom of the slide to the inner top of the battery compartment. The lower end of the magnetic piston plate is elastically connected to the inner bottom of the slide through two second return springs.

[0012] As a preferred embodiment of the above technical solution, after the first electromagnet and the second electromagnet are energized, they repel each other with the same polarity of the adjacent surfaces of the magnetic piston plate. The upper ends of the two rectangular cavities are provided with placement slots, and the two placement slots are connected to the lower rectangular cavities. Bluetooth headsets can be placed in the two placement slots.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. When the rechargeable battery is depleted, the user can energize the first electromagnet. When energized, the first electromagnet will exert a strong repulsive force on the magnetic piston plate. Under this repulsive force, the magnetic piston plate will move downward, causing the two second push rods to move downward as well, pushing the rechargeable battery out of the battery compartment. After the rechargeable battery is recharged, the first electromagnet will be turned off. At this time, after the magnetic piston plate returns to its initial position, the battery interface of the rechargeable battery will be aligned with the multiple connectors, and then it can be placed into the battery compartment. This will not affect the normal use of the Bluetooth headset.

[0015] 2. When the Bluetooth headset needs to be used, the second electromagnet is energized. After the second electromagnet is energized, it will exert a large repulsive force on the magnetic piston plate. Under the action of the repulsive force, the magnetic piston plate will move upward and drive the two first push rods to move upward, pushing the top of the Bluetooth headset out of the placement slot, so that the Bluetooth headset can be easily taken out for use.

Each of the two first magnetic blocks 14 cooperates with the adjacent second magnetic block 15. An earphone ejection mechanism and a battery ejection mechanism are provided on the upper part of the battery compartment 16.

[0022] When the rechargeable battery 17 is depleted, the user can energize the first electromagnet 5. When the first electromagnet 5 is energized, it will exert a large repulsive force on the magnetic piston plate 10. Under the repulsive force, the magnetic piston plate 10 will move down and drive the two second push rods 8 down, pushing the rechargeable battery 17 out of the battery compartment 16. After the rechargeable battery 17 is recharged, the first electromagnet 5 is turned off. At this time, after the magnetic piston plate 10 returns to its initial position, the battery interface 19 of the rechargeable battery 17 is aligned with the multiple connectors 20, and then it is put into the battery compartment 16. This will not affect the normal use of the Bluetooth headset.

[0023] like Figure 1-3As shown, the upper end of the rechargeable battery 17 is provided with two battery interfaces 19, and the upper end of each of the two battery interfaces 19 is provided with a connector 20. The front side of the casing 1 is provided with multiple speaker holes 22, and the right side of the multiple speaker holes 22 is provided with a first display screen 23 and a second display screen 24 from top to bottom.

[0024] like Figure 1 As shown, the first display screen 23 is used to view the time and the battery level of the casing 1, the second display screen 24 is used to view the remaining battery level of the rechargeable battery 17, the lower end of the second display screen 24 is provided with a charging port 25, and the right side of the charging port 25 is provided with a power switch 26.

[0025] like Figure 2 As shown, the headphone pop-out mechanism includes a slide groove 9 opened inside the housing 1. The slide groove 9 is located above the battery compartment 16. There are mounting slots 7 at both the upper and lower parts of the slide groove 9. A first electromagnet 5 is installed in the upper mounting slot 7, and a second electromagnet 6 is installed in the lower mounting slot 7. A magnetic piston plate 10 is slidably connected between the left and right inner walls of the slide groove 9. Two rectangular cavities 4 are opened at the upper part of the slide groove 9. Two first push rods 3 are fixedly connected to the upper end of the magnetic piston plate 10. The upper ends of the two first push rods 3 extend through the inner top of the slide groove 9 into the rectangular cavity 4. The upper end of the magnetic piston plate 10 is elastically connected to the inner top of the slide groove 9 through two first return springs 11.

[0026] like Figure 2 As shown, the battery ejection mechanism includes two second push rods 8 fixedly connected to the lower end of the magnetic piston plate 10. The lower ends of the two second push rods 8 extend through the inner bottom of the slide groove 9 to the inner top of the battery compartment 16. The lower end of the magnetic piston plate 10 is elastically connected to the inner bottom of the slide groove 9 through two second return springs 12.

[0027] like Figure 2 As shown, after the first electromagnet 5 and the second electromagnet 6 are energized, they repel each other with the same polarity of the adjacent surfaces of the magnetic piston plate 10. The upper ends of the two rectangular cavities 4 are provided with placement slots 2, and the two placement slots 2 are connected to the lower rectangular cavities 4. Bluetooth headsets can be placed in the two placement slots 2.

[0028] When the second electromagnet 6 is energized, it will exert a large repulsive force on the magnetic piston plate 10. Under the repulsive force, the magnetic piston plate 10 will move upward and drive the two first push rods 3 to move upward, pushing the upper end of the Bluetooth headset out of the placement slot 2.

[0029] Working principle: When the rechargeable battery 17 is depleted, the user can energize the first electromagnet 5. When the first electromagnet 5 is energized, it will exert a large repulsive force on the magnetic piston plate 10. Under the repulsive force, the magnetic piston plate 10 will move down and drive the two second push rods 8 to move down, pushing the rechargeable battery 17 out of the battery compartment 16. After the rechargeable battery 17 is recharged, the first electromagnet 5 is turned off. At this time, after the magnetic piston plate 10 returns to its initial position, the battery interface 19 of the rechargeable battery 17 is aligned with the multiple connectors 20, and then it is put into the battery compartment 16. This will not affect the normal use of the Bluetooth headset.

[0030] When the Bluetooth headset needs to be used, the second electromagnet 6 is energized. After the second electromagnet 6 is energized, it will exert a large repulsive force on the magnetic piston plate 10. Under the repulsive force, the magnetic piston plate 10 will move upward and drive the two first push rods 3 to move upward, pushing the upper end of the Bluetooth headset out of the placement slot 2, so that the Bluetooth headset can be easily taken out for use.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
