Description

Technical Field

[0001] This utility model relates to the field of ear clip Bluetooth headset technology, and in particular to an adaptive ear clip Bluetooth headset. Background Technology

[0002] In today's society, Bluetooth headsets have become an indispensable electronic product in people's daily lives. Among them, clip-on Bluetooth headsets are increasingly favored by users due to their unique wearing method and stylish appearance. The biggest feature of clip-on Bluetooth headsets is their wearing method. They are securely fixed to the ear by clipping on it. When wearing them, the curved silicone ear tips fit snugly against the ear, preventing them from going into the ear and causing excessive pressure.

[0003] A search revealed a clip-on Bluetooth earphone with publication number CN211557448U, comprising an earbud portion and a hook portion integrally formed for clamping the lower end of the ear. The earbud portion and hook portion are U-shaped, with multiple sound outlet holes on the inner side of the earbud portion. Magnetic engaging components are respectively provided at the ends of the earbud portion and the hook portion. This U-shaped Bluetooth earphone facilitates clamping the lower end of the ear, has a lightweight structure, and the magnetic engaging components secure the earphone through magnetic attraction, preventing the sound from directly impacting the eardrum and causing damage, which is common with in-ear earphones during prolonged wear. It also prevents the earphone from falling out easily, improving user comfort.

[0004] When the device in the disclosed patent is in use, the earplug part and the hook part are fixed together. Although the hook part can be used to clamp the user's ear with adaptive elasticity, the clamping force is large for users with thick ears, which increases the user's discomfort. Utility Model Content

[0005] In response to the technical problem in existing patents where the earbud and hook are fixed together during use, although the hook can be used to elastically clamp the ear to the user's ear, the clamping force is too strong for users with thick ears, increasing the user's discomfort, this utility model provides an adaptive ear-clamping Bluetooth headset.

[0006] The technical solution adopted by this utility model is: an adaptive clip-on Bluetooth headset, comprising:

[0007] The hook portion has a first end fixed with a plug block, and one side of the plug block is elastically slidably fitted with a limit pin.

[0008] The earbud portion has a slot at its first end, which corresponds to the insertion block. The inner wall of the slot has a limiting groove, which corresponds to the limiting pin. A pressing block is elastically slidably fitted on the side of the earbud portion. The sliding direction of the pressing block is perpendicular to the sliding direction of the limiting pin and parallel to the side direction of the first end of the earbud portion. The pressing block corresponds to the limiting pin and has multiple anti-slip protrusions on one side.

[0009] Furthermore, the earplug portion has a sliding groove on its side, which is connected to the limiting groove. The first end of the extrusion block is slidably fitted in the sliding groove. A rubber sealing sheet is provided on the side of the extrusion block near the limiting pin and the inner wall of the sliding groove. The anti-slip protrusion is located outside the sliding groove.

[0010] Furthermore, the first end of the extrusion block is provided with a notch, and a first spring damper is provided between the inner wall of the notch and the inner wall of the chute.

[0011] Furthermore, the extrusion block has an L-shaped strip structure, the second end of the extrusion block is slidably fitted in the limiting groove, the limiting pin has a right-angled trapezoidal strip structure, the first end of the limiting pin extends into the limiting groove, the first end of the limiting pin has an inclined surface, and the inclined surface corresponds to the extrusion block.

[0012] Furthermore, the side of the plug block is provided with a groove, the second end of the limiting pin is slidably engaged in the groove, and a second spring damper is provided between the second end of the limiting pin and the inner wall of the groove.

[0013] Furthermore, the plug block has a T-shaped block structure, the slot has a T-shaped groove structure, and the second end of the earplug has a sound outlet hole.

[0014] The beneficial effects of this utility model are:

[0015] When the hook clamping force is too strong or too weak during wear, and a different size hook needs to be replaced, the anti-slip protrusion pushes the squeezing block to slide. The squeezing block squeezes the inclined surface of the limiting pin, releasing the limiting pin's restriction, which facilitates quick removal of the hook. The plug on the new hook is then inserted into the slot on the earbud, allowing the limiting pin to be elastically squeezed into the limiting groove by the inclined surface. This improves the efficiency of hook replacement and is suitable for users with different ear thicknesses. The hook's elasticity ensures a stable and comfortable clamping on the user's ear.

[0016] By setting a rubber sealing sheet, it is easy to flatten the rubber sealing sheet when the first spring damper pulls the extrusion block to reset. This allows the rubber sealing sheet to seal the sliding area reserved for the extrusion block in the slide groove, reducing the probability of dust entering the slide groove and affecting the sliding of the extrusion block.

[0017] By setting the sliding direction of the squeezing block to be perpendicular to the sliding direction of the limiting pin, and the sliding direction of the squeezing block to be parallel to the side direction of the first end of the earbud, it is easier to avoid the side of the earbud being subjected to vertical force when the earbud is accidentally dropped, causing the squeezing block to slide and the hook part to separate from the earbud part. Compared with the traditional side pressing to release the limit, this reduces the probability of the earbud being damaged when it is accidentally dropped, which would increase the rolling distance caused by the hook part separating from the earbud part.

[0027] To address the problems existing in the background art, this application proposes the following technical solution:

[0028] An adaptive clip-on Bluetooth headset, comprising:

[0029] Hook part 1, the first end of hook part 1 is fixed with plug block 101, and one side of plug block 101 is elastically slidably engaged with limit pin 102;

[0030] The earplug part 2 has a slot 201 at its first end, which corresponds to the plug block 101. The inner wall of the slot 201 has a limiting groove 202, which corresponds to the limiting pin 102. The side of the earplug part 2 is elastically slidably fitted with a pressing block 203. The sliding direction of the pressing block 203 is perpendicular to the sliding direction of the limiting pin 102. The sliding direction of the pressing block 203 is parallel to the side direction of the first end of the earplug part 2. The pressing block 203 corresponds to the limiting pin 102. A plurality of anti-slip protrusions 204 are provided on one side of the pressing block 203.

[0031] Furthermore, the earplug part 2 has a sliding groove 205 on its side, which is connected to the limiting groove 202. The first end of the extrusion block 203 is slidably fitted in the sliding groove 205. The side of the extrusion block 203 near the limiting pin 102 and the inner wall of the sliding groove 205 are provided with a rubber sealing sheet 206. The anti-slip protrusion 204 is located outside the sliding groove 205.

[0032] Furthermore, the first end of the extrusion block 203 is provided with a notch 207, and a first spring damper 208 is provided between the inner wall of the notch 207 and the inner wall of the slide groove 205.

[0033] Furthermore, the extrusion block 203 has an L-shaped strip structure, and the second end of the extrusion block 203 is slidably fitted in the limiting groove 202. The limiting pin 102 has a right-angled trapezoidal strip structure, and the first end of the limiting pin 102 extends into the limiting groove 202. The first end of the limiting pin 102 is provided with an inclined surface 103, which corresponds to the extrusion block 203.

[0034] Furthermore, the plug block 101 has a groove 104 on its side, the second end of the limiting pin 102 is slidably fitted in the groove 104, and a second spring damper 105 is provided between the second end of the limiting pin 102 and the inner wall of the groove 104.

[0035] Furthermore, the plug block 101 has a T-shaped block structure, the slot 201 has a T-shaped groove structure, and the second end side of the earplug part 2 is provided with a sound outlet 3.

[0036] Working principle: When the clamping force of the hook part 1 is too strong or too weak during wear, and a different specification of hook part 1 needs to be replaced, the anti-slip protrusion 204 pushes the compression block 203 to slide, causing the first spring damper 208 to stretch and compress the rubber sealing sheet 206 to deform and bend. The compression block 203 compresses the inclined surface 103 of the limiting pin 102, causing the limiting pin 102 to slide out of the limiting groove 202, releasing the limiting pin 102. Then, the hook part 1 is pulled, causing the plug block 101 to slide out of the slot 201 on the earplug part 2, facilitating quick removal of the hook part 1. The anti-slip protrusion 204 is released, the first spring damper 208 pulls the compression block 203 back to its original position, and pulls the rubber sealing sheet 206 to flatten it. This allows the rubber sealing sheet 206 to seal the sliding area reserved for the compression block 203 in the slide groove 205, reducing the probability of dust entering the slide groove 205, and allowing the new hook part 1 to be easily removed. The hook part 1 inserts the plug 101 into the slot 201 on the earbud part 2, so that the limiting pin 102 is squeezed and elastically locked into the limiting groove 202 by the inclined surface 103. This facilitates quick installation of the hook part 1, improves the efficiency of replacing the hook part 1, and is suitable for users with different ear thicknesses. The hook part 1 is held stably and comfortably on the user's ear by its elasticity. By setting the sliding direction of the squeezing block 203 to be perpendicular to the sliding direction of the limiting pin 102, and the sliding direction of the squeezing block 203 to be parallel to the side direction of the first end of the earbud part 2, it is easy to avoid the squeezing block 203 sliding and causing the hook part 1 to separate from the earbud part 2 when the earphone is accidentally dropped. Compared with the traditional side pressing to release the limit, this reduces the probability of the hook part 1 separating from the earbud part 2 and increasing the rolling distance when the earphone is accidentally dropped, thus reducing the probability of earphone damage.
