Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a replaceable battery module for headphones. Background Technology

[0002] With the popularization and development of mobile terminal devices, the high-capacity and high-power performance of lithium-ion batteries has attracted increasing attention. Historically, due to current collection issues, the lithium battery industry has generally believed that low-capacity conventional batteries are produced using a small cylindrical process, while high-capacity or high-power batteries are produced using a prismatic stacking process. Lithium-ion batteries have advantages such as high energy density, small size, long storage life, and no pollution, making them a clean energy source that the country is currently vigorously developing. Prismatic lithium-ion batteries are widely used due to their large capacity and ease of use.

[0003] However, due to limitations in battery physical size and the need for lightweight products, their energy storage capacity often cannot be expanded indefinitely. This means that in certain usage environments, batteries need to be replaced periodically to maintain continuous device operation, such as the batteries in wireless headphones.

[0004] The batteries in existing removable and replaceable headphones are usually fixed inside the headphones with clips. However, this design, which is simple in structure and lacks sufficient fixing force, often causes the batteries to loosen during use. Loose batteries may cause power interruption or poor contact, interfering with the normal operation of the device.

[0005] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a replaceable battery module for headphones, which enhances the stability of the battery module installation and positioning, reduces the probability of the battery module becoming loose, and ensures normal operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A replaceable battery module for headphones includes a frame and a battery cell installed within the frame. The upper surface of the frame has a protruding positioning boss, and the upper surface of the positioning boss has a recessed embedding groove. A positioning block is embedded in the embedding groove. The upper surface of the positioning block has a plurality of oblique protrusions, which are arranged at intervals along a left-right direction. The oblique protrusions protrude from the upper surface of the positioning boss. The lower side of the frame has snap-fit ​​grooves on both the front and rear sides. A PCB board is located at the inner bottom of the frame. The battery cell is connected to the PCB board. A conductive part is connected to the lower end of the PCB board, and the conductive part protrudes from the lower surface of the frame.

[0009] As a preferred embodiment, the inner sidewall of the upper opening of the embedding groove is provided with a first inclined stop wall, and the peripheral sidewall of the upper end of the positioning block is provided with a second inclined stop wall. The positioning block is inserted into the embedding groove from top to bottom, and the second inclined stop wall is constrained by the first inclined stop wall.

[0010] As a preferred embodiment, the front and rear sidewalls of the positioning block are provided with a number of protruding ribs, which are arranged sequentially at intervals along the left-right direction and extend along the up-down direction. One surface of the protruding rib abuts against the inner sidewall of the embedding groove.

[0011] As a preferred embodiment, the front side of the frame is recessed with a receiving cavity, the battery cell is installed in the receiving cavity, and a steel sheet is covered at the front opening of the receiving cavity.

[0012] As a preferred embodiment, the outer periphery of the frame is covered with a protective film, which covers the steel sheet.

[0013] As a preferred embodiment, the inner bottom of the frame is provided with a mounting cavity, which is connected to the receiving cavity, and the PCB board is mounted in the mounting cavity.

[0014] As a preferred embodiment, the lower surface of the frame is recessed upwards with a relief hole, the relief hole is connected to the mounting cavity, and the lower end of the conductive part passes through the relief hole.

[0015] As a preferred embodiment, a nickel sheet is connected to the upper end of the PCB board, and the electrodes of the battery cell are connected to the nickel sheet.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves protruding a positioning boss on the upper surface of the frame, with an embedding groove recessed on the upper surface of the positioning boss. A positioning block is embedded in the embedding groove, and several oblique protrusions are protruding from the upper surface of the positioning block, so that the oblique protrusions protrude from the upper surface of the positioning boss. Furthermore, snap-fit ​​grooves are provided on both the front and rear sides of the lower side of the frame. In this way, an upper positioning structure is formed at the upper end of the battery module through the positioning boss, positioning block, and oblique protrusions, and a front and rear positioning structure is formed at the lower end of the battery module through the snap-fit ​​grooves. This enhances the stability of the battery module installation and positioning, reduces the probability of the battery module loosening, and ensures normal operation.

[0037] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of the replaceable battery module for headphones provided in an embodiment of the present invention.

[0038] The headphone uses a replaceable battery module, including a plastic frame 10 and a battery cell 20 installed inside the plastic frame 10. The upper surface of the plastic frame 10 is provided with a positioning boss 11, and the upper surface of the positioning boss 11 is provided with a recessed embedding groove 12. The embedding groove 12 is embedded with a positioning block 30. In this embodiment, the upper surface of the positioning boss 11 is in the shape of an upwardly convex arc. Correspondingly, the upper surface of the positioning block 30 is in the shape of an upwardly convex arc. The upper surface of the positioning block 30 is flush with the upper surface of the positioning boss 11. The positioning block 30 is a plastic block. The positioning boss 11 and the positioning block 30 are used together for installation and positioning with the mounting and positioning structure inside the headphone.

[0039] The upper surface of the positioning block 30 is provided with a plurality of oblique protrusions 31, which are arranged at intervals along the left and right direction. The oblique protrusions 31 protrude from the upper surface of the positioning boss 11. The front and rear sides of the lower side of the frame 10 are provided with snap-fit ​​grooves 13, which are used to snap-fit ​​with the snap-fit ​​buckles inside the headphones. The inner bottom of the frame 10 is provided with a PCB board 40, the battery cell 20 is connected to the PCB board 40, and the lower end of the PCB board 40 is connected to a conductive part 41, which is exposed on the lower surface of the frame 10.

[0041] The positioning block 30 has several protruding ribs 33 on its front and rear side walls. The protruding ribs 33 are arranged at intervals along the left and right directions. The protruding ribs 33 extend in the up and down directions. One surface of the protruding rib 33 abuts against the inner side wall of the embedding groove 12. The lower end surface of the protruding rib 33 is flush with the lower surface of the positioning block 30. The upper end of the protruding rib 33 extends to the lower end of the second inclined stop wall 32. Here, the protruding ribs 33 can enhance the positioning stability between the positioning block 30 and the embedding groove 12.

[0042] The front side of the frame 10 is recessed with a receiving cavity 15, and the battery cell 20 is installed in the receiving cavity 15. A steel sheet 50 is covered at the front opening of the receiving cavity 15, which can provide better protection for the battery cell 20. In this embodiment, a positioning groove 16 is provided on the frame 10 around the front opening of the receiving cavity 15. The positioning groove 16 is connected to the receiving cavity 15. The steel sheet 50 is installed and positioned in the positioning groove 16. A slot (not shown in the figure) is provided on the upper side of the positioning groove 16 on the frame 10. A locking block 51 protrudes backward on the upper side of the steel sheet 50 and engages in the slot.

[0043] The outer periphery of the frame 10 is covered with a protective film 60, which covers the steel sheet 50 to provide protection; the protective film 60 may be a rubber film.

[0044] The inner bottom of the frame 10 is provided with a mounting cavity 17, which is connected to the receiving cavity 15. The PCB board 40 is mounted in the mounting cavity 17, and a nickel sheet 42 is connected to the upper end of the PCB board 40. The electrode 21 of the battery cell 20 is connected to the nickel sheet 42. The lower surface of the frame 10 is recessed with a clearance hole 18, which is connected to the mounting cavity 17. The lower end of the conductive part 41 passes through the clearance hole 18. In this embodiment, two sets of conductive parts 41 are provided, and the two sets of conductive parts 41 are arranged at a left-right distance. Each set includes four conductive parts 41 arranged at a left-right distance. Correspondingly, the clearance hole 18 is provided on the lower surface of the frame 10 for each conductive part 41.

[0045] In summary, the key design feature of this utility model lies in the fact that a positioning boss is protruded from the upper surface of the frame, and an embedding groove is recessed on the upper surface of the positioning boss. A positioning block is embedded in the embedding groove, and several oblique protrusions are protruding from the upper surface of the positioning block, so that the oblique protrusions protrude from the upper surface of the positioning boss. Furthermore, snap-fit ​​grooves are provided on both the front and rear sides of the lower side of the frame. In this way, an upper positioning structure is formed at the upper end of the battery module through the positioning boss, positioning block, and oblique protrusions, and a front and rear positioning structure is formed at the lower end of the battery module through the snap-fit ​​grooves. This enhances the stability of the battery module installation and positioning, reduces the probability of the battery module becoming loose, and ensures normal operation.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
