Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a spring-loaded Bluetooth headset charging dock. Background Technology

[0002] Bluetooth earphones utilize Bluetooth technology to achieve wireless connectivity, freeing users from the hassle of tangled wires. Currently, Bluetooth earphones typically use a charging case with a charging dock for charging, with charging methods mainly including POGO PIN and spring-loaded designs. POGO PIN designs are complex, usually requiring three basic components: a pin shaft, a spring, and a pin tube. This makes assembly more complex, increases costs, and requires individual surface mount assembly, resulting in low efficiency. Spring-loaded designs are simpler than POGO PIN designs, but their protruding structure from the base leads to poor stability and affects conductive contact. To address this, Chinese utility model patent CN217335856U discloses a user-friendly Bluetooth earphone charging base. It uses two irregularly shaped springs (shaped one and two) in conjunction with the base housing and PCB circuit board. When the earphone charging cap is inserted, the elasticity of these two springs ensures the charging cap's stability and prevents it from loosening. The solution also has the following problems: First, the heads of the two springs are suspended and exposed, which not only affects the stability of the springs, but also makes them more susceptible to damage. Second, a structure with springs, slides and locking blocks is needed to limit the springs and lock them in place, but this structure is relatively complex and the assembly is cumbersome. Third, the protrusions on both sides of the base shell form independent structures with poor strength. When the earphone is inserted for charging, it is easy to squeeze and deform it to the sides, affecting the stability of the charging contact. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a spring-loaded Bluetooth headset charging dock that features a simpler structure, more reasonable design, higher structural strength, more stable and reliable contact, protection of the spring contacts, and easier assembly.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a spring-loaded Bluetooth headset charging dock, comprising a base, a first spring, and a second spring. The base has a raised first mounting portion and a raised second mounting portion, forming a charging slot for headset insertion between the first and second mounting portions. Spring slots are respectively provided on the first and second mounting portions, with the first and second springs respectively inserted into the spring slots of the first and second mounting portions. A first mounting hole is formed by the spring slot of the first mounting portion extending towards the charging slot, and a second mounting hole is formed by the spring slot of the second mounting portion extending towards the charging slot. The first spring head of the first spring is inserted into the first mounting hole, and the second spring head of the second spring is inserted into the second mounting hole, with the bottom of the base blocking both the first and second spring heads. A connecting wall is also provided on the base, connecting the first and second mounting portions into a single structure.

[0005] Furthermore, the spring slot includes a fixing slot and a limiting slot. The limiting slot is recessed in the fixing slot, so that the cross-section formed by the limiting slot and the fixing slot is a "convex" shaped structure. A protruding stop portion is provided in the limiting slot. An outwardly inclined stop spring arm is provided on the first fixing piece of the first spring and the second fixing piece of the second spring. When the first spring and the second spring are respectively installed into the spring slots of the first mounting part and the second mounting part, the two stop spring arms are respectively embedded in the corresponding limiting slots and pressed by the corresponding stop portions, so as to fix the first spring and the second spring respectively.

[0006] Furthermore, the first fixing piece and the second fixing piece are respectively provided with outwardly protruding parts at the tail positions. The fixing groove has a structure that is narrow at the top and wide at the bottom. The main body of the first fixing piece and the main body of the second fixing piece are respectively embedded in the upper narrow part of the corresponding fixing groove, while the outward protruding parts are respectively stuck in the lower wide part of the corresponding fixing groove.

[0007] Preferably, the stop is located in the middle of the limiting groove, and the stop does not protrude from the fixing groove to avoid interfering with the fixing piece of the spring.

[0008] Preferably, the first and second springs are not facing each other directly, and the planes on which the two springs are located form an angle between 90 and 150 degrees, such as 120 degrees. This reduces the space required for the two springs to extend outward, thereby reducing the overall length of the charging base.

[0009] Preferably, the shape of the first spring is different from that of the second spring, and the length of the first spring extending into the charging slot is greater than the length of the second spring extending into the charging slot.

[0010] Furthermore, the tail end of the first spring has a first pin, and the tail end of the second spring has a second pin. The first pin extends from the first mounting hole to the bottom surface of the base, and the second pin extends from the second mounting hole to the bottom surface of the base, for connecting the circuit board.

[0011] Preferably, the connecting wall is located at the rear edge of the base, connecting the rear of the first mounting part to the rear of the second mounting part, and the height of the connecting wall is less than the height of the first mounting part and the second mounting part.

[0012] Preferably, the lower wide section of the fixing groove has an inclined flared structure that gradually narrows from the bottom inwards, so as to facilitate the insertion of the spring piece from the bottom.

[0013] This invention protects the spring by inserting its head into the base, preventing it from being suspended and exposed, thus improving its stability. A limiting groove and a stop within the spring slot, working in conjunction with the stop arm on the spring, stably fix the spring within the slot. This limiting structure is simpler, more effective, and easier to assemble. Furthermore, a connecting wall between the two mounting parts enhances the overall structural strength, thereby improving product reliability. Attached Figure Description

Detailed implementation manners

[0022] In this embodiment, referring to Figures 1-7 , the shrapnel type Bluetooth headset charging base includes a base 1, a first shrapnel 2 and a second shrapnel 3. The base 1 is provided with raised first and second mounting portions 11 and 12. A charging slot 13 for inserting the headset is formed between the first mounting portion 11 and the second mounting portion 12. Shrapnel slots 14 are respectively provided on the first mounting portion 11 and the second mounting portion 12. The first shrapnel 2 and the second shrapnel 3 are respectively inserted into the shrapnel slots 14 of the first mounting portion 11 and the second mounting portion 12. The shrapnel slot 14 of the first mounting portion 11 extends towards the charging slot 13 to form a first mounting hole 15, and the shrapnel slot 14 of the second mounting portion 12 extends towards the charging slot 13 to form a second mounting hole 16. The first shrapnel head 25 of the first shrapnel 2 is inserted into the first mounting hole 14, and the second shrapnel head 35 of the second shrapnel 3 is inserted into the second mounting hole 16. The bottom of the base 1 blocks the first shrapnel head 25 and the second shrapnel head 35, so that the two shrapnel heads are not exposed, thereby protecting the shrapnel heads. A connecting wall 17 is further provided on the base 1, and the connecting wall 17 connects the first mounting portion 11 and the second mounting portion 12 into an integral structure, thereby improving the structural strength of the two mounting portions.

[0023] The shrapnel slot 14 includes a fixing slot 141 and a limiting slot 142. The limiting slot 142 is recessed in the fixing slot 141, so that the cross-section formed by the limiting slot 142 and the fixing slot 141 is a "convex" shaped structure. A raised stop portion 143 is provided in the limiting slot 142. Stop spring arms 24 and 34 that extend outwards obliquely are provided on the first fixing piece 21 of the first shrapnel 2 and the second fixing piece 31 of the second shrapnel 3 respectively. The first shrapnel 2 and the second shrapnel 3 are respectively inserted into the shrapnel slots 14 of the first mounting portion 11 and the second mounting portion 12 after passing through the first mounting hole 15 and the second mounting hole 16 from the bottom. The two stop spring arms 24 and 34 are respectively embedded into the corresponding limiting slots 142 and are tightened by the stop portion 143 after passing over the stop portion 143, so as to respectively fix the first shrapnel 2 and the second shrapnel 3, so that the shrapnel cannot be withdrawn towards the bottom.

[0024] Outwardly protruding portions 22 and 32 are respectively provided at the tail positions of the first fixing piece 21 and the second fixing piece 31. The fixing groove 141 has a structure that is narrow at the top and wide at the bottom. The main body of the first fixing piece 21 and the main body of the second fixing piece 31 are respectively embedded in the upper narrow section of the corresponding fixing groove 141, while the outwardly protruding portions 22 and 32 are respectively stuck in the lower wide section of the corresponding fixing groove 141. This prevents the spring piece from moving further upward, thus achieving the locking of the spring piece.

[0025] The stop part 143 is located in the middle of the limiting groove 142, and the stop part 143 does not protrude from the fixing groove 141 to avoid interfering with the fixing piece of the spring.

[0026] The first spring 2 and the second spring 3 are not facing each other. The planes on which the two springs are located form an angle between 90 and 150 degrees, such as 120 degrees. This reduces the space required for the two springs to extend outward, thereby reducing the length of the entire charging base.

[0027] The shape of the first spring 2 is different from that of the second spring 3. The length of the first spring 2 extending into the charging slot 13 is greater than the length of the second spring 3 extending into the charging slot 13.

[0028] The first spring 2 has a first pin 23 at its tail end, and the second spring 3 has a second pin 33 at its tail end. The first pin 23 extends from the first mounting hole 15 to the bottom surface of the base 1, and the second pin 33 extends from the second mounting hole 16 to the bottom surface of the base 1, for connecting the circuit board.

[0029] The connecting wall 17 is located at the rear edge of the base 1, and the rear part of the first mounting part 11 and the rear part of the second mounting part 12 are connected by the connecting wall 17, and the height of the connecting wall 17 is less than the height of the first mounting part 11 and the second mounting part 12.

[0030] The lower wide section of the fixing groove 141 has an opening that gradually narrows from the bottom inwards, forming an inclined flared structure to facilitate the insertion of the spring piece from the bottom.

[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
