DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] With the continuous development of headphones, wired headphones that need to be plugged into terminals have gradually developed into wireless headphones that are connected to terminal Bluetooth. In order to protect wireless headphones, they can be wrapped in headphone protective cases. Some headphone protective cases have a groove structure inside, and an air bag is formed between the groove structure and the wireless headphones, which can provide a certain buffer for the headphones when they fall. However, this air bag does not provide good protection for the headphones. When the headphones are impacted, most of the force still acts directly on the headphones.

[0028] Specifically, when an airbag is formed by a groove structure directly set inside the earphone protective shell, the structure at the edge of the airbag will directly impact the surface of the earphone when subjected to force, and when the airbag is deformed, its edge structure will also directly scratch the surface of the earphone, which can easily scratch the earphone.

[0029] In order to alleviate the above-mentioned technical problems, the utility model proposes a new earphone protective case, which includes a charging compartment protective case 10 and a charging cover protective case 20. One of the charging compartment protective case 10 and the charging cover protective case 20 has a closed buffer cavity 33. When the earphone 40 wearing the earphone protective case falls or is subjected to other impacts, the buffer cavity 33 deforms to absorb the impact force. Moreover, the inner wall of the earphone protective case is always in smooth contact with the earphone 40. The deformation of the buffer cavity 33 has less impact on the earphone 40, which can improve the protective effect of the earphone protective case on the earphone 40.

[0030] The earphone protective case provided by the embodiment of the utility model is now described.

[0031] Please also read Figures 1 to 3 The earphone protective shell is used to wrap around the surface of the earphone 40 to protect the earphone 40. The earphone 40 includes a charging compartment 41, a charging cover 42 rotatably connected to the charging compartment 41, and an earphone body. When the earphone body is not in use, it can be placed in the charging compartment 41 and charged by the charging compartment 41. The earphone protective shell includes a charging compartment protective shell 10 and a charging cover protective shell 20.

[0032] The charging compartment protective shell 10 has a first accommodating space, and the first accommodating space is used to accommodate the charging compartment 41 . Therefore, the charging compartment protective shell 10 is used to protect the charging compartment 41 .

[0033] The charging cover protection case 20 has a second accommodation space, and the second accommodation space is used to accommodate the charging cover 42 . Therefore, the charging cover protection case 20 is used to protect the charging cover 42 .

[0034] At least one of the charging compartment protective shell 10 and the charging cover protective shell 20 includes a shell structure, and the interior of the shell structure has a closed buffer cavity 33. Specifically, the following three situations are included: the interior of the charging compartment protective shell 10 has a closed buffer cavity 33; or the interior of the charging cover protective shell 20 has a closed buffer cavity 33; or the interiors of the charging compartment protective shell 10 and the charging cover protective shell 20 both have a closed buffer cavity 33.

[0035] In order to protect and fit the earphone 40 tightly, the earphone protective shell is adapted to the shape of the earphone 40 , and the shell structure of the earphone protective shell can be understood as a thin-walled structure, that is, a buffer cavity 33 is provided in the wall of the thin-walled structure.

[0036] Since the buffer cavity 33 is closed, when the earphone protective shell is impacted, most of the impact force can be absorbed by the deformation of the buffer cavity 33. Moreover, when the buffer cavity 33 is deformed, the inner wall of the shell structure is always in smooth contact with the surface of the earphone 40, and the impact force on the earphone 40 is small. Therefore, the earphone 40 can be better protected and the surface of the earphone 40 will not be scratched.

[0037] The earphone protective shell in the above embodiment includes a charging case protective shell 10 and a charging cover protective shell 20. At least one of the charging case protective shell 10 and the charging cover protective shell 20 has a closed buffer cavity 33. When the sealed buffer cavity 33 is impacted, the buffer cavity 33 is deformed, and most of the impact force is absorbed by the deformation of the buffer cavity 33. The impact force directly acting on the earphone 40 is small, which can form a more effective protection for the earphone 40.

[0038] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 The buffer cavity 33 in the charging compartment protective shell 10 is arranged in the area corresponding to the surface of the charging compartment 41, that is, the charging compartment protective shell 10 is a hollow structure, and the cavity inside it is the buffer cavity 33. In this way, all parts of the charging compartment 41 can be protected by the buffer cavity 33, and any position of the charging compartment 41 that is impacted can be buffered by the buffer cavity 33.

[0039] In some embodiments of the present invention, please refer to Figure 2 The buffer cavity 33 in the charging cover protective shell 20 is arranged in the area corresponding to the surface of the charging cover 42, that is, the charging cover protective shell 20 is a hollow structure, and the cavity inside it is the buffer cavity 33. In this way, all parts of the charging cover 42 can be protected by the buffer cavity 33, and any position of the charging cover 42 that is impacted can be buffered by the buffer cavity 33.

[0040] In some embodiments of the present invention, please refer to Figure 4The shell structure includes a first shell 31 and a second shell 32 connected to each other, and the edges of the first shell 31 and the second shell 32 are sealed to form a sealed buffer cavity 33. The shell structure is formed by connecting the first shell 31 and the second shell 32. After the first shell 31 and the second shell 32 are sealed to each other, a sealed buffer cavity 33 can be formed. Among them, at least part of the first shell 31 or at least part of the second shell 32 is the inner wall of the shell structure, which can directly contact the surface of the earphone 40, and the remaining part is the outer wall of the shell structure.

[0041] By arranging the first shell 31 and the second shell 32 to be connected to each other to form the buffer chamber 33, the processing difficulty of the shell structure can be reduced, and the production cost of the shell structure can be reduced.

[0042] In some embodiments, the first shell 31 and the second shell 32 are processed and formed separately, and then the edges of the first shell 31 and the second shell 32 are sealed and connected by hot-melt fixing, ultrasonic connection, etc.

[0043] In some embodiments of the present invention, the buffer cavity 33 is an air bag, that is, the buffer cavity 33 is filled with air. When the first shell 31 and the second shell 32 are connected, a cavity filled with air will naturally be formed therein without the need for additional gas filling.

[0044] In some embodiments of the present invention, please refer to Figure 4 The first shell 31 is used to be arranged close to the earphone 40, and the second shell 32 is arranged relative to the first shell 31 and away from the earphone 40, and the connection between the first shell 31 and the second shell 32 is located at the edge of the shell structure. The shell structure can be regarded as a thin-walled structure, and the shell structure has a receiving cavity 101, and the receiving cavity 101 has an opening. The edge of the thin-walled structure is the position of the shell structure close to the opening. In this embodiment, the first shell 31 is equivalent to the inner layer structure of the shell structure, and the second shell 32 is equivalent to the outer layer structure of the shell structure. The edge of the shell structure is arranged between the inner layer structure and the outer layer structure.

[0045] By arranging the connection between the first shell 31 and the second shell 32 at the edge of the shell structure, the processing of the shell structure is simpler, and the edges of the two sheet shells can be connected to each other to form a closed cavity.

[0046] In some embodiments, the first shell 31 and the second shell 32 are both integrally formed and both have a accommodating cavity 101 . The second shell 32 is sleeved on the outside of the second shell 32 , so that the charging compartment 41 or the charging cover 42 can be set inside the accommodating cavity 101 .

[0047] In some embodiments, the first housing 31 can be divided into multiple parts and molded separately, and the second housing 32 can also be divided into multiple parts and molded separately.

[0048] In other embodiments of the present invention, the connection between the first shell 31 and the second shell 32 and the edge of the shell structure may also be located at other positions.

[0049] In some embodiments of the present invention, please refer to Figure 4 and Figure 5 The first housing 31 includes an inner wall layer 311 for being closely arranged on the earphone 40 and a protruding structure 312 connected to the inner wall layer 311, and the edge of the second housing 32 is connected to the protruding structure 312. The first housing 31 includes an inner wall layer 311 and a protruding structure 312 connected to each other, the protruding structure 312 is located at the edge of the inner wall layer 311, and the protruding structure 312 is connected to the second housing 32.

[0050] By providing a protruding structure 312 at the edge of the inner wall layer 311, an air cavity of a certain thickness, i.e., the above-mentioned buffer cavity 33, can be formed between the inner wall layer 311 and the second shell 32. The height of the protruding structure 312 can be the thickness of the buffer cavity 33, and a gap is formed between the first shell 31 and the second shell 32 by the protruding structure 312.

[0051] In some embodiments, the protrusion structure 312 is disposed at the opening of the shell structure, that is, at the installation entrance of the charging compartment 41 or the charging cover 42 .

[0052] In some embodiments of the present invention, please refer to Figure 4 and Figure 5 The protruding structure 312 includes a first connecting wall 3121, a second connecting wall 3122, and a third connecting wall 3123 that are bent and connected in sequence. The first connecting wall 3121 is connected to the inner wall layer 311 at a side away from the second connecting wall 3122, and the second connecting wall 3122 and / or the second connecting wall 3122 are connected to the second shell 32. The inner wall layer 311, the first connecting wall 3121, the second connecting wall 3122, and the third connecting wall 3123 are bent and connected in sequence. The inner wall layer 311 is the main structure of the first shell 31, the protruding structure 312 is the edge structure of the first shell 31, and at least one of the second connecting wall 3122 and the third connecting wall 3123 is connected to the second shell 32.

[0053] By configuring the protruding structure 312 as a plurality of connecting walls connected in sequence, the amount of raw materials used in the first shell 31 can be reduced, and the wall thickness of each part of the first shell 31 can be made more consistent, thereby avoiding injection defects such as pores and sand holes, and improving the quality of injection molding.

[0054] In some embodiments, the inner wall layer 311 is vertically connected to the first connecting wall 3121, the first connecting wall 3121 is vertically connected to the second connecting wall 3122, and the second connecting wall 3122 is vertically connected to the third connecting wall 3123. Such an arrangement facilitates the processing and forming of the protruding structure 312 and increases the structural strength of the protruding structure 312. In this embodiment, the cross section of the protruding structure 312 is a gate shape, and the second connecting wall 3122 is the top wall of the gate-shaped structure.

[0055] In other embodiments of the present invention, the protruding structure 312 is a solid structure, the inner wall layer 311 is connected to one side of the protruding structure 312 , and the other side of the protruding structure 312 can be connected to the second shell 32 .

[0056] In some embodiments of the present invention, please refer to Figure 4 and Figure 5 The second shell 32 includes an outer wall layer 321 and a fourth connecting wall 322 that is bent and connected to the outer wall layer 321, and the fourth connecting wall 322 is connected to the protruding structure 312. The outer wall layer 321 and the fourth connecting wall 322 are bent and connected, so that the second shell 32 forms a bent structure at its edge, which facilitates the connection between the second shell 32 and the protruding structure 312.

[0057] By arranging the fourth connecting wall 322 on the outer wall layer 321, an overlapping structure is formed between the first shell 31 and the second shell 32, which makes it easier to connect the two and improves the sealing performance after the two are connected.

[0058] In some embodiments, the outer wall layer 321 and the fourth connecting wall 322 are vertically connected to facilitate the processing and forming of the second shell 32 .

[0059] In some embodiments, the fourth connecting wall 322 is connected to the third connecting wall 3123 of the protruding structure 312 .

[0060] In some embodiments, a portion of the outer wall layer 321 close to the fourth connecting wall 322 is connected to the second connecting wall 3122 of the protruding structure 312 .
