Technical Field

[0001] This application relates to the technical field of electronic devices, specifically to an earphone case. Background Technology

[0002] In related technologies, headphone cases typically include an upper shell assembly and a lower shell assembly, and the upper shell assembly can rotate relative to the lower shell assembly to put the headphone case in a closed or open state. However, how to limit the rotation angle of the upper shell assembly relative to the lower shell assembly and prevent the headphone case from being opened excessively is a technical problem that urgently needs to be solved. Utility Model Content

[0003] This application provides an earphone case, comprising: a lower shell assembly, including a lower shell and a lower support, the lower support being disposed on the lower shell and used to support the earphone, the lower support and the lower shell cooperating to form a first accommodating space; an upper shell assembly, disposed on the lower shell assembly and cooperating with the lower shell assembly to form a second accommodating space, the second accommodating space being used to accommodate the earphone; and a pivot assembly for pivotally connecting the upper shell assembly and the lower shell assembly, the pivot assembly including a connector, one end of the connector being fixedly connected to the upper shell assembly, the other end of the connector being inserted into the first accommodating space and pivotally connected to the lower shell assembly; wherein, after the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the connector abuts against the lower shell and the lower support.

[0004] In some embodiments, the lower shell assembly includes a pivot side and an opening / closing side disposed opposite to each other. The pivot assembly is disposed on the pivot side, and the lower shell assembly has a first opening on the pivot side. The first opening is formed by the lower support and the lower shell together. The connector is inserted into the first receiving space through the first opening. The peripheral area of ​​the first opening includes two longitudinal edges and two transverse edges disposed opposite to each other. The longitudinal edges extend along the rotation axis between the upper shell assembly and the lower shell assembly. Each transverse edge connects the two longitudinal edges. The connector is configured to abut against the lower shell and the lower support in the peripheral area of ​​the first opening.

[0005] In some embodiments, the connector includes a first connecting portion, a first transition portion, and an abutting portion disposed within a first accommodating space. The first connecting portion is pivotally connected to the lower housing assembly, the first transition portion is connected to the first connecting portion, and when the upper housing assembly is in a closed state relative to the lower housing assembly, at least a portion of the first transition portion extends from the first connecting portion toward the interior of the first accommodating space. The abutting portion is connected to the first transition portion and is configured to abut against the lower housing assembly in the peripheral region of the first opening.

[0006] In some embodiments, the abutment portion is disposed at at least one end of the first transition portion along the rotation axis, and after the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the abutment portion abuts against the lower support at the corresponding lateral edge.

[0007] In some embodiments, the lower support includes a main body and a peripheral side portion disposed around the main body, the peripheral side portion extending toward the lower shell relative to the main body; after the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the abutting portion abuts against the inner surface of the peripheral side portion at the corresponding lateral edge.

[0008] In some embodiments, the abutment portion is disposed at one end of the first transition portion away from the first connecting portion, and after the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the abutment portion abuts against the lower support at one of its longitudinal edges.

[0009] In some embodiments, there are multiple abutment portions arranged along the rotation axis. After the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the multiple abutment portions abut against the lower wall surface of the lower support at one of its longitudinal edges.

[0010] In some embodiments, the lower support is provided with two positioning protrusions, which are disposed within a first accommodating space. A first connecting portion is disposed between the two positioning protrusions. The pivot assembly also includes a pivot, which passes through the first connecting portion and the two positioning protrusions. Each positioning protrusion is disposed at a corresponding lateral edge.

[0011] In some embodiments, the connector further includes a second transition portion connected to the first transition portion. When the upper shell assembly is in a closed state relative to the lower shell assembly, the second transition portion extends from the first transition portion toward the outside of the first accommodating space and toward the upper shell assembly. After the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the second transition portion abuts against the lower shell at one of its other longitudinal edges.

[0012] In some embodiments, the second transition portion includes an abutment section and a transition section, the abutment section connecting the first transition portion and the transition section. When the upper shell assembly is in a closed state relative to the lower shell assembly, the abutment section is located within the first accommodating space and extends at least partially from the first transition portion toward the upper shell assembly, and at least partially from the abutment section toward the outside of the first accommodating space. After the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the abutment section rotates to the top of the lower shell and abuts against the upper end face of the lower shell at another longitudinal edge. The transition section extends downward from the abutment section to approach the outer periphery of the upper shell assembly.

[0013] In some embodiments, the upper shell assembly includes an upper shell and an upper support, and the connector further includes a second connecting portion connected to the second transition portion. The second connecting portion is disposed between the upper shell and the upper support and is fixedly connected to the upper shell and / or the upper support.

[0014] In some embodiments, the second connecting portion is provided with at least one adhesive groove, and the second connecting portion is fixed to the upper shell and / or the upper support by adhesive. The adhesive at least partially fills the adhesive groove, and the upper shell and / or the upper support are provided with protruding ribs embedded in the adhesive groove.

[0015] In some embodiments, the lower shell includes a lower shell body and a first metal ring. The first metal ring is supported on the outer periphery of the lower shell body, and the lower support is supported on the first metal ring. The lower shell body, the first metal ring, and the lower support cooperate to form a first accommodating space. After the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the connector abuts against the first metal ring.

[0016] In some embodiments, the upper shell assembly includes an upper shell, a second metal ring, and an upper support. The second metal ring is disposed along the edge of the upper shell, and the inner ring surface of the second metal ring is stepped to form a support platform spaced apart from the lower end surface of the second metal ring. The upper support is supported on the support platform, and the upper support, the second metal ring, and the upper shell cooperate to form a third accommodating space. The connector is inserted into the third accommodating space.

[0017] In some embodiments, the upper end face of the first metal ring includes an exposed area that is exposed relative to the lower support. The exposed area is close to the outer ring surface of the first metal ring. When the upper shell assembly is in a closed state relative to the lower shell assembly, the lower end face of the second metal ring abuts against the exposed area of ​​the first metal ring.

[0018] By setting the connector to simultaneously abut against the lower shell and the lower support after the upper shell assembly is opened to a predetermined angle relative to the lower shell assembly, the following advantages are achieved: First, it prevents the upper shell assembly from rotating further, keeping it at the preset angle relative to the lower shell assembly and preventing the headphone case from being over-opened. Second, the lower shell and the lower support work together to provide stable support for the connector, improving the stability of the headphone case when open and reducing the possibility of the upper shell assembly wobbling relative to the lower shell assembly. Third, the torque and impact force generated when the upper shell assembly is opened can be simultaneously distributed on the lower shell and the lower support, preventing pressure from being concentrated solely on either the lower shell or the lower support, thus avoiding damage to the lower shell or the lower support due to excessive force.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Please refer to the following: Figure 1 and Figure 2 This application provides an earphone case 100 for storing earphones. The earphone case 100 includes a lower shell assembly 23, an upper shell assembly 21, and a pivot assembly 22. The lower shell assembly 23 and the upper shell assembly 21 are pivotally connected via the pivot assembly 22. The lower shell assembly 23 has a pivot side 2306 and an opening / closing side 2307 oppositely disposed therefrom, and the pivot assembly 22 is disposed on the pivot side 2306 of the lower shell assembly 23. Specifically, the pivot assembly 22 includes a connector 220, the first end of which is fixedly connected to the upper shell assembly 21, and the second end of which is pivotally connected to the lower shell assembly 23. That is, the connector 220 can drive the upper shell assembly 21 to rotate relative to the lower shell assembly 23 about a preset rotation axis R, so that the earphone case 100 is in a certain position. Figure 1 The closed state shown, or, Figure 2The open state is shown.

[0031] like Figure 2 As shown, the lower shell assembly 23 includes a lower shell 241 and a lower support 234. The lower support 234 covers the lower shell 241 and cooperates with the lower shell 241 to form a first accommodating space 23b. The pivot side 2306 of the lower shell assembly 23 may be provided with a first opening 2343, and the second end of the connector 220 is inserted into the first accommodating space 23b through the first opening 2343.

[0032] like Figure 2 and Figure 5 As shown, the lower support 234 is used to support the headphones. In some embodiments, in the closed state, the upper shell assembly 21 covers the lower shell assembly 23 and cooperates with the lower shell assembly 23 to form a second receiving space 20a. When the headphones are supported on the lower support 234, they are accommodated in the second receiving space 20a.

[0033] By setting the connector 220 to abut against the lower shell 241 and the lower support 234 after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the following advantages are achieved: First, the upper shell assembly 21 is prevented from rotating further, thus maintaining the upper shell assembly 21 at a preset angle relative to the lower shell assembly 23 and preventing the headphone case 100 from being over-opened. Second, the lower shell 241 and the lower support 234 work together to provide stable support for the connector 220, which helps improve the stability of the headphone case 100 in the open state and reduces the possibility of the upper shell assembly 21 shaking relative to the lower shell assembly 23. Third, the torque and impact force generated by the upper shell assembly 21 when it is opened can be simultaneously distributed on the lower shell 241 and the lower support 234, preventing the pressure from being concentrated solely on the lower shell 241 or the lower support 234, thereby preventing damage to the lower shell 241 or the lower support 234 due to excessive force.

[0034] It should be noted that the ideal situation desired by this application is that after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the connecting member 220 abuts against the lower shell 241 and the lower support 234. However, due to processing errors during production, manufacturing, and assembly, or due to wear and tear, in actual products, when the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, there may be a small gap between the connecting member 220 and one of the lower shell 241 and the lower support 234, which is usually less than or equal to 2mm. Therefore, when the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, and the minimum gap between the connecting member 220 and one of the lower shell 241 and the lower support 234 is less than or equal to 2mm, it can be considered to meet the inventive purpose of this application and is within the scope of protection of this application.

[0035] It should be noted that the "open state" mentioned in this application refers to the state after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23. For example, see reference to Figure 2 The "closed state" mentioned in this application refers to the state in which the upper shell assembly 21 is closed over the lower shell assembly 23, as can be seen from [reference needed]. Figure 1 The "predetermined angle" mentioned in this application refers to the angle that facilitates the taking out and putting away of the headphones when they are in the open state. The range can be between 75° and 120°, such as 75°, 90°, 100°, 110°, 120°, etc. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0036] In some embodiments, such as Figure 2 and Figure 4 As shown, the first opening 2343 is jointly formed by the lower shell 241 and the lower support 234, that is, a portion of the lower shell 241 and a portion of the lower support 234 together constitute the peripheral area of ​​the first opening 2343. The peripheral area of ​​the first opening 2343 may include two opposing longitudinal edges 2343a and two opposing transverse edges 2343b. The longitudinal edges 2343a extend along the rotation axis R between the upper shell assembly 21 and the lower shell assembly 23, and each transverse edge 2343b connects to two longitudinal edges 2343a.

[0037] For example, the longitudinal edge 2343a may be parallel to the rotation axis R between the upper shell assembly 21 and the lower shell assembly 23, and the transverse edge 2343b may be perpendicular to the rotation axis R between the upper shell assembly 21 and the lower shell assembly 23. It should be noted that "parallel" as used in this application refers to approximately parallel; for example, an angle of less than 15° between the two can be understood as parallel. Similarly, "perpendicular" as used in this application refers to approximately perpendicular; for example, an angle of less than 75°-105° between the two can be understood as perpendicular.

[0038] In some embodiments, the connector 220 can be inserted into the first receiving space 23b via the first opening 2343, and configured to abut against the lower shell 241 and the lower support 234 in the peripheral region of the first opening 2343. This configuration allows the peripheral region of the first opening 2343 to limit the connector 220, which facilitates a tight fit between the connector 220 and the lower shell assembly 23, thereby saving space.

[0039] Please refer to the following: Figure 5 and Figure 6In some embodiments, the connector 220 includes a first connecting portion 2201, a first transition portion 2202, and an abutment portion 2205 disposed within the first accommodating space 23b. The first connecting portion 2201 is pivotally connected to the lower housing assembly 23. For example, the pivot assembly 22 may further include a pivot 221, which may pass through at least a portion of the structure on the first connecting portion 2201 and the lower support 234, such that the first connecting portion 2201 is pivotally connected to the lower support 234.

[0040] like Figures 4 to 6 As shown, in some embodiments, the first connecting portion 2201 is connected to the first transition portion 2202, and the abutting portion 2205 is connected to the first transition portion 2202. In the closed state, at least a portion of the first transition portion 2202 extends from the first connecting portion 2201 toward the interior of the first accommodating space 23b. The abutting portion 2205 is provided with a first abutting surface 2205a. In the closed state, the first abutting surface 2205a may be located on the side of the abutting portion 2205 opposite to the lower shell 241. It should be noted that the "connection of the abutting portion 2205 and the first transition portion 2202" described in this application can mean that the abutting portion 2205 and the first transition portion 2202 are directly connected, or that the abutting portion 2205 is indirectly connected to the first transition portion 2202 through the first connecting portion 2201. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0041] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the abutment portion 2205 is disposed at at least one end of the first transition portion 2202 along the rotation axis R on the pivot side. Accordingly, after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the abutment portion 2205 can abut against the lower support 234 at the corresponding lateral edge 2343b, so that the connector 220 and the lower shell assembly 23 are tightly fitted, thereby saving space. Specifically, the first abutment surface 2205a of the abutment portion 2205 can be used to abut against the lower support 234.

[0042] Specifically, the lower support 234 may include a main body 234a and a peripheral portion 234b surrounding the main body 234a, the peripheral portion 234b extending relative to the main body 234a towards the lower shell 241. When the earphone case 100 is in the open state, the abutment portion 2205 may abut against the inner surface 234p of the peripheral portion 234b at the lateral edge 2343b. The inner surface 234p of the peripheral portion 234b refers to the side surface of the peripheral portion 234b closest to the first accommodating space 23b.

[0043] Specifically, such as Figure 4 and Figure 8 As shown, the abutment portion 2205 is disposed at the end of the first transition portion 2202 away from the first connecting portion 2201. Correspondingly, after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the abutment portion 2205 can abut against the lower support 234 at one of its longitudinal edges 2343a, so that the connector 220 and the lower shell assembly 23 fit tightly together, thereby saving space. Specifically, the abutment portion 2205 can abut against the lower wall surface of the lower support 234 at one of its longitudinal edges 2343a. Here, the lower wall surface of the main body portion 234a refers to the surface of the main body portion 234a near the lower shell 241.

[0044] In some embodiments, when the abutment portion 2205 is disposed at the end of the first transition portion 2202 away from the first connecting portion 2201, the number of abutment portions 2205 can be multiple. These multiple abutment portions 2205 are evenly distributed along the rotation axis R on the first transition portion 2202. After the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the multiple abutment portions 2205 can abut against the lower wall surface of the lower support 234 at one of its longitudinal edges 2343a. By providing multiple abutment portions 2205 abutting against the first limiting portion, the abutment area is increased, allowing the first transition portion 2202 to be force-balanced when the earphone case 100 is in the open state, which further improves the stability of the earphone case 100 in the open state.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, two positioning protrusions 2345 can be provided on the lower support 234, and the two positioning protrusions 2345 can be disposed within the first accommodating space 23b. The connector 220 can be disposed between the two positioning protrusions 2345, and the pivot 221 passes through the first connecting part 2201 and the two positioning protrusions 2345, so that the first connecting part 2201 and the lower support 234 are pivotally connected.

[0046] like Figure 4 and Figure 7 As shown, each positioning protrusion 2345 is set at the corresponding lateral edge 2343b. When assembling the connector 220, the connector 220 can be accurately positioned, reducing the assembly difficulty of the connector 220. In addition, it is also conducive to the tight fit between the connector 220 and the lower support 234, thereby improving the space utilization rate.

[0047] like Figure 5 and Figure 6As shown, in some embodiments, the connector 220 further includes a second transition portion 2203 connected to the first transition portion 2202. When the upper shell assembly 21 is in a closed state relative to the lower shell assembly 23, the second transition portion 2203 extends from the first transition portion 2202 toward the outside of the first accommodating space 23b and toward the upper shell assembly 21, and a second abutment surface 2203p is provided on the side of the second transition portion 2203 near the first connecting portion 2201.

[0048] like Figure 2 , Figure 4 and Figure 9 As shown, after the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the second transition portion 2203 abuts against the lower shell 241 at one of its other longitudinal edges 2343a. Specifically, the second transition portion 2203 can rotate to be above the lower shell 241, and abut against the upper end face 239p of the lower shell 241 at one of its other longitudinal edges 2343a.

[0049] like Figure 5 and Figure 6 As shown, in some embodiments, the second transition portion 2203 includes an abutment section 2203a and a transition section 2203b, with the abutment section 2203a connecting the first transition portion 2202 and the transition section 2203b. In the closed state, the abutment section 2203a is located within the first accommodating space 23b and extends at least partially from the first transition portion 2202 toward the upper housing assembly 21, while at least a portion of the transition section 2203b extends from the abutment section 2203a toward the outside of the first accommodating space 23b.

[0050] like Figure 6 and Figure 9 As shown, the second abutment surface 2203p is disposed on the side of the abutment section 2203a facing the first connecting portion 2201, and the transition section 2203b extends downward from the abutment section 2203a to approach the outer periphery of the upper shell assembly 21. This arrangement allows the second abutment surface 2203p of the abutment section 2203a to rotate to the top of the lower shell 241 when in the open state, and to abut against the upper end face 239p of the lower shell 241 at another longitudinal edge 2343a. Furthermore, the transition section 2203b extends downward from the abutment section 2203a to approach the outer periphery of the upper shell assembly 21, ensuring that after the headphone case 100 returns to the closed state from the open state, the outer periphery of the upper shell assembly 21 can align with the outer periphery of the lower shell assembly 23, thus improving the appearance of the headphone case 100 and optimizing its overall size.

[0051] exist Figure 8In the illustrated embodiment, when in the open state, the connector 220 can abut against the lower wall surface of the lower support 234 and the upper end surface 239p of the lower shell 241. This arrangement allows the lower support 234 and the lower shell 241 to limit the connector 220 on both the upper and lower sides, which helps to further improve the stability of the earphone case 100 in the open state and reduces the possibility of the upper shell assembly 21 shaking relative to the lower shell assembly 23 in the open state.

[0052] Please refer to the following: Figure 3 and Figure 5 In some embodiments, the upper shell assembly 21 may include an upper shell 212 and an upper support 211, the upper shell 212 and the upper support 211 cooperating to form a third receiving space 21b. The connector 220 also includes a second connecting portion 2204 connected to the second transition portion 2203, the second connecting portion 2204 being inserted into the third receiving space 21b and fixedly connected to the upper shell 212 and / or the upper support 211. Exemplarily, the second connecting portion 2204 may be fixedly connected to the upper shell 212.

[0053] In general, the connector 220 may include a first connecting portion 2201, a first transition portion 2202, a second transition portion 2203, and a second connecting portion 2204 arranged sequentially, as well as an abutment portion 2205 disposed on the first transition portion 2202. Specifically, the first connecting portion 2201 is pivotally connected to the lower shell assembly 23, and the second connecting portion 2204 is fixedly connected to the upper shell assembly 21, so that the upper shell assembly 21 can rotate relative to the lower shell assembly 23.

[0054] In some embodiments, the second connecting portion 2204 is provided with at least one adhesive groove 2204a, and the upper shell 212 is provided with a rib embedded in the adhesive groove 2204a. Adhesive at least partially fills the adhesive groove 2204a, and the second connecting portion 2204 is fixed to the upper shell 212 by adhesive. By providing the adhesive groove 2204a on the second connecting portion 2204 and the rib on the upper support 211 of the upper shell 212, the bonding area between the second connecting portion 2204 and the upper shell 212 can be increased, thereby achieving reliable fixation between the second connecting portion 2204 and the upper shell assembly 21.

[0055] In some embodiments, the second connecting portion 2204 may also be fixedly connected to the upper support 211. Accordingly, the opening of the adhesive receiving groove 2204a may face the upper support 211, and the upper support 211 may be provided with a protruding rib embedded in the adhesive receiving groove 2204a. Alternatively, in some embodiments, the second connecting portion 2204 may also be fixedly connected to both the upper shell 212 and the upper support 211. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0056] like Figure 3 and Figure 5 As shown, the lower shell 241 includes a lower shell body 230 and a first metal ring 239. The first metal ring 239 is supported on the outer periphery of the lower shell body 230, and a lower support 234 is supported on the upper end face 239p of the first metal ring 239. For example, the material of the lower shell body 230 can be plastic, and the first metal ring 239 can be made of metal. Since the first metal ring 239 is made of metal, metal has strong wear resistance and deformation resistance. Supporting the lower support 234 on the first metal ring 239 helps to improve the overall strength of the lower shell assembly 23.

[0057] Specifically, the lower shell body 230, the first metal ring 239, and the lower support 234 cooperate to form the first accommodating space 23b. After the upper shell assembly 21 is opened to a predetermined angle relative to the lower shell assembly 23, the connector 220 abuts against the upper end face 239p of the first metal ring 239. Since the first metal ring 239 is made of metal, which has strong wear resistance and deformation resistance, by setting the connector 220 to abut against the upper end face 239p of the first metal ring 239, the situation where the lower shell 241 cannot effectively limit the connector 220 due to wear or deformation is avoided.

[0058] like Figure 3 and Figure 5 As shown, the upper shell assembly 21 also includes a second metal ring 213, which is disposed along the edge of the upper shell 212. The inner ring surface of the second metal ring 213 is stepped to form a support platform 213a spaced apart from the lower end surface 213b of the second metal ring 213. For example, the upper shell 212 may be made of plastic, while the second metal ring 213 may be made of metal. Due to the strong wear resistance and deformation resistance of metal, supporting the upper support 211 on the inner ring surface of the second metal ring 213 helps to improve the overall strength of the upper shell assembly 21.

[0059] When the headphone case 100 is in the closed state, the lower end face 213b of the second metal ring 213 can abut against the upper end face 239p of the first metal ring 239. When the headphone case 100 is in the closed state, the upper shell assembly 21 and the lower shell assembly 23 abut against each other through the two metal rings. Since metal has strong wear resistance and deformation resistance, it is beneficial to improve the overall strength of the headphone case 100 in the closed state and improve the durability of the headphone case 100.

[0060] Specifically, the upper support 211, the second metal ring 213, and the upper shell 212 cooperate to form the third accommodating space 21b. For example... Figure 5 and Figure 7 As shown, connector 220 can be inserted into the third accommodating space 21b.

[0061] like Figure 2 and Figure 5As shown, in some embodiments, the upper end face 239p of the first metal ring 239 includes an exposed area 239a that is exposed relative to the lower support 234. The exposed area 239a is close to the outer ring surface of the first metal ring 239. When the upper shell assembly 21 is in a closed state relative to the lower shell assembly 23, the lower end face 213b of the second metal ring 213 abuts against the exposed area 239a of the first metal ring 239.
