Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a wireless Bluetooth over-ear headphone that is easy to store. Background Technology

[0002] With the accelerating pace of life and increased travel frequency, the demand for portable and easy-to-store electronic products is also increasing. As a commonly used audio device, over-ear wireless Bluetooth headphones need to be easily stored when not in use to avoid damage or loss and to facilitate carrying when going out. Therefore, ease of storage has become an important consideration in the design and development of over-ear wireless Bluetooth headphones.

[0003] With the continuous development and maturation of Bluetooth technology, headphones have gradually broken free from the constraints of cables, achieving wireless connectivity and bringing users greater freedom of movement. From the early Bluetooth 2.0 and 3.0 to the current Bluetooth 5.0 and above, data transmission stability and sound quality have been significantly improved, making wireless headphones increasingly popular in the market. Over-ear wireless Bluetooth headphones have also emerged to meet people's needs for convenient and comfortable wearing experience.

[0004] Over-ear headphones typically consist of a headband, earcups, and headphone body. Compared to other types of headphones, they are larger and irregularly shaped, which requires more space for storage and makes them difficult to put in ordinary small bags or pockets, causing inconvenience to users.

[0005] Therefore, this utility model provides an easy-to-store over-ear wireless Bluetooth headset to solve the above problems. Summary of the Invention

[0006] This invention provides a portable wireless Bluetooth headset, designed to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A conveniently stored over-ear wireless Bluetooth headset includes a headband plastic component. Both sides of the outer arc surface of the headband plastic component have clearance notches. An arc-shaped groove is formed on the side of the headband plastic component near the clearance notches. A fixing through hole is formed in the middle section of the top of the outer arc surface of the headband plastic component. Limiting inclined plates are formed on both sides of the inner wall of the fixing through hole. The limiting inclined plates are distributed on both sides of the headband plastic component. An alignment hole is formed at the bottom end of one side surface of each limiting inclined plate. Shrinkage components are connected through to both end faces of the headband plastic component. The shrinkage component includes a pressure plate connected through to one end of the headband plastic component. The top of the outer arc surface of the pressure plate has a bearing surface, which is fitted and connected to the inner arc surface of the headband plastic component.

[0009] Preferably, the outer arc surface of the bearing surface is provided with limiting grooves on both sides, and the inner arc surface of the limiting groove is connected to a fixed platform. The top of the fixed platform is provided with a contact slope, which is adapted to the arc groove at the top.

[0010] Preferably, the bottom end of the fixed platform is provided with a braking ramp, one side surface of the braking ramp abuts and is adapted to the limiting ramp, and both sides of the outer arc surface of the pressing plate are provided with limiting blocks, the lower surface of the limiting blocks is engaged with the inner side wall of the clearance notch.

[0011] Preferably, the limiting block is placed on the top of the outer arc surface of the head beam plastic part, and the pressing plate has a fitting surface on the side near the limiting block, and the upper surface of the fitting surface is provided with a clearance groove.

[0012] Preferably, the inner arc surface of the relief groove is movably engaged with an L-shaped abutment, and the two ends of the L-shaped abutment are attached to the surface of the head beam plastic part.

[0013] Preferably, there are two L-shaped abutments, which are distributed in a mirror-symmetrical manner on both sides of the pressure plate, and a spring is fixedly installed between the two L-shaped abutments.

[0014] Preferably, a hinge shaft is fixedly installed on the lower surface of the pressure plate, one end of the hinge shaft is provided with a bearing, and one end of the hinge shaft is movably connected to an earphone cover through the bearing. Beneficial effects

[0015] The earcups can overlap freely thanks to their connection with the bearings, which effectively reduces the lateral space occupied. At the same time, the internal space of the headband plastic parts on both sides is continuously compressed under the continuous action of the pressure plate, further optimizing the storage effect from the vertical dimension. This two-pronged approach improves the overall space utilization, making the earphones more compact and convenient to store. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an easy-to-store over-ear wireless Bluetooth headset, such as... Figures 1 to 5As shown, the device includes a head beam plastic component 1. Both sides of the outer arc surface of the head beam plastic component 1 have clearance notches 101. An arc-shaped groove 102 is formed on the side of the head beam plastic component 1 near the clearance notches 101. A fixing through hole 103 is formed in the middle section of the top of the outer arc surface of the head beam plastic component 1. Limiting inclined plates 104 are formed on both sides of the inner wall of the fixing through hole 103. The limiting inclined plates 104 are distributed on both sides of the head beam plastic component 1. A notch is formed at the bottom end of one side surface of the limiting inclined plate 104. The headband plastic part 1 has alignment holes 105. Shrinkage components 2 are connected through to both ends of the headband plastic part 1. Each shrinkage component 2 includes a pressure plate 201 connected through to one end of the headband plastic part 1. The top of the outer arc surface of the pressure plate 201 has a bearing surface 202, which is in contact with the inner arc surface of the headband plastic part 1. Limiting grooves 203 are formed on both sides of the outer arc surface of the bearing surface 202. A fixing platform 204 is connected through the inner arc surface of the limiting groove 203. The top of the platform 204 is provided with a contact slope 205, which is adapted to the arc groove 102 at the top. The bottom of the fixed platform 204 is provided with a braking slope 206, one side surface of which abuts against the limiting slope 104. Limiting blocks 207 are provided on both sides of the outer arc surface of the pressure plate 201. The lower surface of the limiting block 207 is engaged with the inner side wall of the clearance notch 101. The limiting block 207 is placed on the top of the outer arc surface of the head beam plastic part 1. The pressure plate 201 has a contact surface 208 on the side near the limiting block 207. The upper surface of the contact surface 208 is provided with a relief groove 209. The inner arc surface of the relief groove 209 is movably engaged with an L-shaped abutment 210. The two ends of the L-shaped abutment 210 are attached to the surface of the head beam plastic part 1. There are two L-shaped abutments 210, which are distributed in a mirror symmetrical manner on both sides of the pressure plate 201. A spring 211 is fixedly installed between the two L-shaped abutments 210.

[0025] During assembly, the end of the head beam plastic part 1 is inserted into the gap between the pressure plate 201 and the mating surface 208. At this time, the pressure plate 201 can tightly press the head beam plastic part 1, effectively preventing its end from bending. Combined with the fixing connection of the fixing platform 204, the stability of the connection between the head beam plastic part 1 and the pressure plate 201 is effectively ensured. When the head beam plastic part 1 is assembled, its clearance notch 101 must first be aligned with the pressure plate 201. In this way, the head beam plastic part 1 can smoothly pass through the limiting block 207 in a direction perpendicular to the bearing surface 202 until it reaches the gap position formed between the bearing surface 202 and the mating surface 208. Then, the head beam plastic part 1 moves in a direction parallel to the bearing surface 202 and inserts into the gap, and is finally firmly pressed on the pressure plate 201. This assembly process not only ensures convenient and efficient operation, but also ensures the accuracy of the relative position of the head beam plastic part 1.

[0026] It is worth mentioning that one of the pressure plates 201 has a limiting groove 203 on its surface opposite the other pressure plate 201. The end face of the pressure plate 201 has a groove structure. When the clearance notch 101 of the head beam plastic part 1 is aligned with the pressure plate 201, and the head beam plastic part 1 passes through the pressure plate 201 in a direction perpendicular to the bearing surface 202, even if there are manufacturing tolerances, the end of the pressure plate 201 will not easily obstruct the passage of the head beam plastic part 1. As part 1 moves gradually, the limiting blocks 207 on both sides will engage with the limiting groove 203. At the same time, after moving a certain distance, the pressure plate 201 will slide along one side of the contact slope 205 across the arc groove 102 and engage with the arc groove 102. Then, the braking slope 206 at the bottom and the limiting slope 104 will fit tightly together to achieve limiting, further strengthening the stability of the connection between the headband plastic part 1 and the pressure plate 201. In this way, under the continuous inward compression of the pressure plates 201 at both ends, the headphone covers 4 on both sides will gradually shrink inward, thereby effectively reducing the overall space ratio.

[0027] The L-shaped abutment 210, which slides and engages with the contact surface 208, abuts against the headband plastic part 1 at both ends during the retraction process. This ensures that the headband will not easily open due to shaking when stored, thus guaranteeing storage stability. On the other hand, when using the headphones, this abutment method causes the L-shaped abutment 210 to compress the spring 211 inward, thereby releasing the restriction on the headband plastic part 1 and allowing the headphones to smoothly return to the working state. The operation is convenient and reliable.

[0028] A hinge shaft 3 is fixedly installed on the lower surface of the pressure plate 201. One end of the hinge shaft 3 is provided with a bearing 301, and one end of the hinge shaft 3 is movably connected to the headphone cover 4 through the bearing 301.

[0029] With this design, the headphone cover 4 can be freely overlapped by connecting with the bearing 301, which effectively reduces the lateral space occupation. At the same time, the internal space of the headband plastic parts 1 on both sides is continuously compressed under the continuous action of the pressure plate 201, which further optimizes the storage effect from the vertical dimension. The two measures work together to greatly improve the overall space utilization, making the headphones more compact and convenient to store.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
