Technical Field
[0001] The utility model relates to the technical field of mobile phone accessories, and particularly relates to a headphone case protective cover. Background Art
[0002] With the rapid development of technology, headphones have become an indispensable electronic product in people's daily lives and are widely used in many fields such as music playback, call communication, and game entertainment. However, during use, headphones are often vulnerable to external impacts such as dropping and squeezing, resulting in damage to the flexible buffer case of the headphones and damage to internal components, thereby affecting the service life and sound quality of the headphones. Therefore, how to effectively protect headphones from external impacts has become an urgent problem to be solved.
[0003] Traditional headphone protection methods mostly use soft materials such as silicone sleeves for wrapping. Although it can reduce the direct damage of the impact on the headphones to a certain extent, due to its lack of sufficient strength and hardness, it cannot effectively resist large impacts. In addition, although some hard protective cases can provide strong protection effects, they often lack sufficient elasticity and are difficult to effectively disperse and absorb energy when impacted, thus unable to comprehensively protect the headphones from damage. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a headphone case protective cover.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] A headphone protective cover, which has a state of being impacted by external forces, includes:
[0007] A flexible buffer case, which is configured to provide elasticity in the state of being impacted by external forces;
[0008] A hard protective case, which is arranged inside the flexible buffer case and is suitable for providing strength in the state of being impacted by external forces. An accommodation cavity for accommodating a headphone case is formed inside the hard protective case;
[0009] Wherein, the hard protective case is fixedly connected to the flexible buffer case, and a buffer cavity is formed between the two to provide shock absorption for the headphone case in the state of being impacted by external forces.
[0010] Furthermore, the hard protective case and the flexible buffer case have adapted openings, and a fixing part is formed at the openings of the hard protective case and the flexible buffer case;
[0011] Wherein, the fixing part includes a sealing step arranged at the opening of the rigid protective shell and / or the flexible buffer shell, and an adhesive part adhered to the sealing step is provided at the opening of the flexible buffer shell and / or the rigid protective shell.
[0012] Further, the sealing step includes a limiting section and a vertical section. The adhesive part abuts against the limiting section, and the length of the vertical section corresponds to the thickness of the buffer cavity.
[0013] Further, the length of the vertical section is 1.2 mm - 3.5 mm.
[0014] Further, the fixing part includes a sealing flange arranged at the opening of the flexible buffer shell / rigid protective shell. A positioning part is also provided between the rigid protective shell and the flexible buffer shell. The positioning part and the fixing part cooperate together to realize the fixation between the rigid protective shell and the flexible buffer shell.
[0015] Further, the positioning part includes a sliding groove and a sliding block cooperating with it. The sliding groove and the sliding block are respectively arranged on the outer side wall of the rigid protective shell and the inner side wall of the flexible buffer shell alternatively.
[0016] Further, the sliding groove is U-shaped. The sliding groove includes a sliding part and a cut-off part. The flange has a notch for cooperating with the end of the sliding block.
[0017] Further, the sealing flange and the sliding groove divide the interior of the buffer cavity into multiple shock-absorbing intervals.

[0040] Embodiment 1:
[0041] Please refer to Figures 1-6 A headphone protective case is disclosed in the present utility model, which has a state of being impacted by an external force. Specifically, the headphone protective case includes a rigid protective shell 2 and a flexible buffer shell 1. The rigid protective shell 2 is made of a rigid material and is adapted to provide strength in the state of being impacted by the external force. An accommodation cavity for accommodating the headphone case is formed inside the rigid protective shell. The flexible buffer shell 1 is made of a flexible material and is configured to provide elasticity in the state of being impacted by the external force. Specifically, the flexible buffer shell 1 is made of TPU or TPEE material, while the rigid protective shell 2 is made of PC material. The rigid protective shell 2 is disposed inside the flexible buffer shell 1 and is fixedly connected to the flexible buffer shell. There is a gap between the outer sidewall of the rigid protective shell 2 and the inner sidewall of the flexible buffer shell 1, and a buffer cavity 3 is formed in the gap between the rigid protective shell 2 and the flexible buffer shell 1. When the headphone battery case drops, the buffer cavity 3 will deform to offset the kinetic energy of the drop, thereby reducing the impact on the headphone battery case and achieving an effect of shock absorption and buffering, and having a better protective effect on the headphone battery case.
[0042] It should be noted that the innovative design of the headphone protective case in the present utility model combines the dual protection mechanisms of the flexible buffer shell and the rigid protective shell. The flexible buffer shell provides elastic buffering when impacted by an external force, effectively dispersing and absorbing the impact energy; the rigid protective shell provides sufficient strength to prevent the flexible buffer shell of the headphone from cracking or the internal components from being damaged. This design achieves a perfect balance between elasticity and strength, significantly improving the protection effect of the headphone.
[0043] In this embodiment, both the flexible buffer shell 1 and the rigid protection shell 2 are split-type. The flexible buffer shell 1 includes a flexible buffer shell body 11 and a flexible buffer shell cover 12, and the rigid protection shell 2 includes a rigid protection shell body 21 and a rigid protection shell cover 22. The rigid protection shell body 21 is sleeved inside the flexible buffer shell body 11, and the rigid protection shell cover 22 is sleeved inside the flexible buffer shell cover 12. The rigid protection shell cover 22 and the flexible buffer shell cover 12 together form a cover part for installing the headphone battery box cover, and the rigid protection shell body 21 and the flexible buffer shell body 11 together form a shell body part for installing the headphone battery box body. And a window 6 for easy operation is reserved between the cover part and the shell body part. Corresponding sockets 5 are provided at the bottoms of the flexible buffer shell body 11 and the rigid protection shell body 21, and the two sockets together form a power socket. It should be noted that a hanging ear 7 is also fixedly connected to the side wall of the flexible buffer shell body 11, and the hanging ear 7 is used to fix a hanging rope or a decorative item.
[0044] Please refer to Figures 7-8 , the rigid protection shell 2 and the flexible buffer shell 1 have matching openings, and the rigid protection shell 2 and the flexible buffer shell 1 form a fixing part 4 at the opening. In this embodiment, the fixing part 4 includes a sealing step 41 arranged at the opening of the rigid protection shell, and the flexible buffer shell 1 has an adhesive part 13 bonded to the sealing step 41 at the opening. The adhesive part 13 is the end of the inner side wall of the flexible buffer shell 1. In some embodiments, the adhesive part 13 can also be a step arranged at the opening of the flexible buffer shell 1 and cooperating with the sealing step 41. In some embodiments, the fixing part 4 includes a sealing step 41 arranged at the opening of the flexible buffer shell 1, and the rigid protection shell 2 has an adhesive part bonded to the sealing step 41 at the opening. The adhesive part is the end of the outer side wall of the rigid protection shell 2. In this embodiment, the sealing step is a double-layer step, and the sealing step 41 includes a limiting section 411 and a vertical section 412. The adhesive part 13 abuts against the limiting section 411. It should be noted that in order to achieve the adaptation between the flexible buffer shell 1 and the flexible buffer shell 1 and facilitate the bonding of glue, the thickness of the limiting section 411 should be slightly greater than the thickness of the contact and abutment of the outer side wall end of the flexible buffer shell 1, or the thickness of the contact and abutment between the limiting section 411 and the outer side wall end of the rigid protection shell 2 should be the same. In addition, the length of the vertical section 412 corresponds to the thickness of the buffer cavity 3. Specifically, the length of the vertical section is 1.2 mm - 3.5 mm to achieve effective buffering when the headphone shell is under external impact.
[0045] When this embodiment is in use, it is only necessary to insert the rigid protective shell 2 into the flexible buffer shell 1 and bond the part where the limiting section contacts and abuts against the outer wall end of the flexible buffer shell 1 at the limiting step, then the fixation between the rigid protective shell 2 and the flexible buffer shell 1 can be achieved. And by respectively sleeving the rigid protective shell body 21 and the rigid protective shell cover 22 outside the shell body and the shell cover of the earphone box, the installation of the present utility model can be realized.
[0046] Embodiment 2:
[0047] The difference between this embodiment and Embodiment 1 is that in this embodiment, the fixing part 4 includes a sealing flange with an opening provided on the flexible buffer shell 1. There is also a positioning part between the rigid protective shell 2 and the flexible buffer shell. The positioning part and the fixing part cooperate together to realize the fixing function between the rigid protective shell 2 and the flexible buffer shell 1. In some actual examples, the fixing part 4 can also be a sealing flange with an opening provided on the rigid protective shell. There is also a positioning part between the rigid protective shell and the flexible buffer shell. The positioning part and the fixing part cooperate together to realize the fixing function between the rigid protective shell 2 and the flexible buffer shell 1. In this embodiment, the positioning part includes a chute and a slider cooperating with it. The chute is arranged on the outer side wall of the rigid protective shell, and the slider is arranged at the corresponding position on the inner side wall of the flexible buffer shell. Specifically, the chute is a U-shaped chute, which includes a sliding part and a stopping part. The flange has a notch for cooperating with the end of the slider. In this embodiment, by the cooperation of the slider and the chute and the stopping of the sliding at the stopping part, at this time, the insertion and cooperation between the end of the slider and the notch can be just achieved. By bonding the flange and the side wall of the rigid protective shell at the opening, the fixation between the rigid protective shell 2 and the flexible buffer shell 1 can be realized.
[0048] As mentioned above, the above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
