Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a Bluetooth headset in which the components are magnetically connected. Background Technology

[0002] Bluetooth headphones are wireless earbuds that can wirelessly connect to mobile phones or other Bluetooth devices to listen to music, make calls, or other audio. The advantages of Bluetooth headphones are that they allow you to listen to music and make calls more comfortably without being dragged around by wires. Bluetooth headphones are also more compact and portable. Bluetooth headphones can also be used to receive calls, allowing users to answer calls without picking up their phones. They also allow you to more easily control music and calls, such as pausing and playing, adjusting the volume, etc. The Bluetooth headphones are usually paired with a charging case for charging, storing, and protecting them when not in use.

[0003] In current technology, people usually carry Bluetooth earphones with them at all times, keeping them in their pockets. However, during outdoor activities such as hiking or running, the smooth surface of the earphone charging case reduces friction between the pocket and the charging case, especially in sports pants pockets, which are often made of polyester fiber, making them even smoother and reducing friction. When the user jumps or sits to rest, the charging case may slip out of the pocket and fall to the ground, causing damage to the charging case and the Bluetooth earphones inside. The impact may also open the lid, causing the earphones to slide out of the charging case. The impact and friction between the earphones and the ground can cause secondary damage. Furthermore, when holding the earphones, since they are usually magnetically connected to the charging case, the magnetic force gradually weakens over time, making it easy for the lid to be accidentally opened, resulting in the earphones falling and getting damaged. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Bluetooth headset with magnetically connected components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a Bluetooth earphone with magnetically connected components, including a charging case, a case cover rotatably connected to one end of the charging case, and the bottom surface of the case cover magnetically connected to the top surface of the charging case, earphone placement cavities symmetrically opened on the top of the charging case, and Bluetooth earphones magnetically connected inside the earphone placement cavities, a plug fixed to the inner wall of the case cover, a slot opened on the top of the charging case, a sliding groove opened on the side wall of the slot, a slider slidably connected to both ends of the sliding groove, and a compression spring fixed between the side of the slider and the side wall of the sliding groove, and a locking roller fixed to the surface of the slider.

[0006] Preferably, the surface of the cover is fixed with a locking plate, the surface of the locking plate has a circular hole, and the surface of the charging compartment is provided with a limiting groove. Each limiting groove is slidably connected with a limiting protrusion. The end of the limiting protrusion is hemispherical. A limiting spring is fixed between the side of the limiting protrusion and the side wall of the limiting groove. This invention also provides a buckle structure on the outer surface of the cover and the charging compartment to further improve the tightness of the connection between the cover and the charging compartment. When the cover is closed, the locking plate on the cover surface squeezes the limiting protrusion on the charging compartment surface into the limiting groove until the limiting protrusion engages with the circular hole. With the help of the elastic force of the limiting spring, the locking plate and the limiting protrusion engage more tightly, thereby further improving the tightness between the cover and the charging compartment.

[0007] Preferably, both sides of the cover are fixed with engaging members, and the surface of the engaging members is provided with a through groove. Both sides of the charging compartment are fixed with side engaging members, and the top of the side engaging members is provided with a hook. This utility model also provides a buckle structure on both sides of the cover and the charging compartment, which further improves the tightness between the cover and the charging compartment. When the cover is closed, the engaging members on both sides of the cover engage with the side engaging members on both sides of the charging compartment, and the hook is limited by the groove, thereby further improving the tightness between the cover and the charging compartment.

[0008] Preferably, the bottom surface of the bite element is set as an inclined surface, and the bottom end of the bite element extends with a lifting protrusion, and the surface of the lifting protrusion is provided with anti-slip protrusions. The inclined surface design facilitates the bite element to pass through the side locking element, the lifting protrusion facilitates the user to open the bite element, and the anti-slip protrusions improve the surface friction of the lifting protrusion.

[0009] Preferably, the plug has semi-circular locking grooves on both the upper and lower end faces, and the plug end is designed as an arc surface, which facilitates the insertion of the plug into the slot.

[0010] Preferably, the inner wall of the semicircular locking groove is provided with anti-slip textures, and the surface of the locking roller is covered with a rubber sleeve. Both the anti-slip textures and the rubber sleeve increase the friction between the semicircular locking groove and the locking roller, further improving the tightness between the plug and the locking roller.

[0011] Preferably, a limiting plate is fixed to the inner wall of the earphone compartment cover, and the limiting plate has an array of limiting grooves on its surface. The limiting plate limits the earphone and prevents the earphone from detaching from the compartment and colliding with the compartment wall when the earphone compartment falls, thus improving the protection of the earphone.

[0012] Beneficial effects

[0013] In current technology, people typically carry Bluetooth earphones in their pockets at all times. However, during outdoor activities such as hiking or running, the smooth surface of the earphone charging case reduces friction between the pocket and the charging case, especially in sports pants pockets, which are often made of polyester fiber, further reducing friction. When the user jumps or sits to rest, the charging case may slip out of the pocket and fall to the ground, causing damage to the charging case and the earphones inside. The impact may also open the case, causing the earphones to slide out. The impact and friction with the ground can then cause further damage. When using Bluetooth earbuds, the magnetic connection between the earbuds and the charging case is usually magnetic. Over time, this magnetic force weakens, making the cover prone to accidental opening and closing, leading to the earbuds falling and getting damaged. To address this issue, this invention employs a snap-fit ​​structure to improve the tightness between the cover and the charging case. A plug is inserted into a slot on the top of the charging case via the inner wall of the cover. The plug presses against a locking roller until it engages with a semi-circular locking groove on the plug's surface. The compression spring further tightens the engagement, ensuring a secure seal between the cover and the charging case. Even if the charging case falls due to slipperiness, the cover and charging case will not easily detach, protecting the Bluetooth earbuds from damage and effectively preventing them from falling or being lost.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-8 A Bluetooth headset with magnetically connected components includes a charging case 1. A cover 2 is rotatably connected to one end of the charging case 1, and the bottom surface of the cover 2 is magnetically connected to the top surface of the charging case 1. Symmetrically shaped earphone placement cavities are formed on the top of the charging case 1, and Bluetooth earphones 3 are magnetically connected inside these cavities. A plug 4 is fixed to the inner wall of the cover 2. Semi-circular locking grooves are formed on both the upper and lower surfaces of the plug 4, and the ends of the plug 4 are curved, facilitating insertion of the plug 4 into slots 101. Anti-slip textures are arrayed on the inner wall of the semi-circular locking grooves, and a rubber sleeve covers the surface of the locking roller 5. Both the anti-slip textures and the rubber sleeve increase the friction between the semi-circular locking grooves and the locking roller 5, further improving the tightness between the plug 4 and the locking roller 5. A slot 101 is formed on the top of the charging case 1, and sliding grooves 1011 are formed on the side walls of the slot 101. Slider 6s are slidably connected to both ends of the sliding grooves 1011, and compression springs 7 are fixed between the sides of the slider 6 and the side walls of the sliding grooves 1011. Locking rollers 5 are fixed to the surface of the slider 6.

[0028] The surface of the cover 2 is fixed with a series of locking plates 8, and the surface of the locking plates 8 has a round hole 801. The surface of the charging compartment 1 is provided with a series of limiting grooves, and each limiting groove is slidably connected with a limiting protrusion 9. The end of the limiting protrusion 9 is hemispherical. A limiting spring 10 is fixed between the side of the limiting protrusion 9 and the side wall of the limiting groove. This utility model also provides a buckle structure on the outer surface of the cover 2 and the charging compartment 1 to further improve the tightness of the connection between the cover 2 and the charging compartment 1. When the cover 2 is closed, the locking plates 8 on the surface of the cover 2 squeeze the limiting protrusions 9 on the surface of the charging compartment 1 into the limiting grooves until the limiting protrusions 9 are engaged with the round hole. With the help of the elastic force of the limiting spring 10, the locking plates 8 and the limiting protrusions 9 are engaged more tightly, thereby further improving the tightness between the cover 2 and the charging compartment 1.

[0029] Both sides of the compartment cover 2 are fixed with a biting member 12. The bottom surface of the biting member 12 is set as a slope 14, and the bottom end of the biting member 12 extends with a lifting protrusion 15. The surface of the lifting protrusion 15 is provided with anti-slip protrusions. The slope 14 is designed to facilitate the biting member 12 to pass through the side locking member 11. The lifting protrusion 15 makes it easy for the user to open the biting member 12. The anti-slip protrusion increases the surface friction of the lifting protrusion 15. The surface of the engaging member 12 is provided with a slot 13. Side engaging members 11 are fixed on both sides of the charging compartment 1. The top of the side engaging member 11 is provided with a hook 1101. The present invention also provides a buckle structure on both sides of the cover 2 and the charging compartment 1, which further improves the tightness between the cover 2 and the charging compartment 1. When the cover 2 is closed, the engaging members 12 on both sides of the cover 2 engage with the side engaging members 11 on both sides of the charging compartment 1. The hook 1101 is limited by the slot 13, thereby further improving the tightness between the cover 2 and the charging compartment 1.

[0030] A limiting plate 16 is fixed to the inner wall of the earphone compartment 2. The limiting plate 16 has a series of limiting grooves 1601 on its surface. The limiting plate 16 limits the earphone and prevents the earphone from falling out of the compartment and colliding with the compartment wall, thus improving the protection of the earphone.

[0031] The working principle of this utility model is as follows: When the cover 2 is closed, the locking plate 8 on the surface of the cover 2 presses the limiting protrusion 9 on the surface of the charging compartment 1 into the limiting groove until the limiting protrusion 9 engages with the round hole. With the help of the elastic force of the limiting spring 10, the locking plate 8 and the limiting protrusion 9 are engaged more tightly. The biting parts 12 on both sides of the cover 2 engage with the side locking parts 11 on both sides of the charging compartment 1. The hook corner 1101 is limited by the slot 13. The plug 4 on the inner wall of the cover 2 is inserted into the slot 101 at the top of the charging compartment 1. The plug 4 presses the locking roller 5 until the locking roller 5 engages with the semi-circular locking groove on the surface of the plug 4. With the help of the elastic force of the compression spring 7, the locking roller 5 and the locking groove are engaged more tightly. The limiting plate 16 limits the earphone to prevent the earphone from falling out of the compartment and colliding with the compartment wall.
