Description

Technical Field

[0001] This utility model belongs to the field of electronic product accessories technology, and in particular relates to a protective cover for an earphone charging case. Background Technology

[0002] With the widespread adoption of wireless earbuds, flip-top charging cases have become the mainstream product form due to their ease of use. To prevent damage or malfunction from collisions and scratches during daily use, users typically equip their charging cases with protective cases. However, most existing charging case cases only offer basic drop and scratch protection, with simple structural designs and significant functional limitations. Specifically: 1. Flip-top charging case lids are prone to accidentally opening during transport, leading to earbuds falling out and being lost, or the charging case becoming contaminated with dust and debris, affecting user experience and device lifespan; 2. In current consumer scenarios, users often need to use electronic devices (such as mobile phones and tablets) to watch videos and make video calls, yet they need to carry additional accessories such as stands. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a protective cover for an earphone charging case, which not only provides basic protection, but also effectively prevents the case cover from popping open and causing the earphones to be lost when dropped. At the same time, it can be easily converted into an angle-adjustable mobile phone stand to improve the user experience.

[0004] To achieve the above objectives, this utility model provides a protective cover for an earphone charging case, suitable for protecting a flip-type earphone charging case, the flip-type earphone charging case including a case body and a cover body, and the protective cover including:

[0005] The protective cover body includes a first housing for fitting onto the compartment and a second housing for fitting onto the cover. The protective cover body is adapted to form a basic protective layer to prevent the charging compartment from being damaged by collisions or scratches.

[0006] The bracket has its two ends pivotally connected to the two sides of the first housing.

[0007] The bracket can be adjusted and rotated to a first position, in which the bracket is located on the rotation path of the cover to restrict the opening of the cover.

[0008] The bracket can also be adjusted and rotated to a second position, in which the bracket and the protective sleeve body together form a herringbone support structure for supporting electronic devices.

[0009] Preferably, when the earphone charging case cover is placed on a horizontal surface and the cover is closed, the first housing is adapted to contact the horizontal surface, which is defined as a reference plane.

[0010] The bracket includes a bracket body and bushings disposed at both ends of the bracket body. When the bracket is in the first position, the orthographic projection of the bracket body on the reference plane at least partially overlaps with the orthographic projection of the second housing on the reference plane. By defining the spatial positional relationship between the bracket and the second housing in the first position, it is ensured that the bracket can accurately prevent the cover from rotating in the first position.

[0011] Preferably, the bracket is configured to fit the shape of the cover; when the bracket is rotated to the first position, it can prevent the cover from rotating upward and opening by contacting or forming a gap with the upper surface of the second housing.

[0012] Preferably, the first housing has shafts on both sides, and the bushings and shafts are adapted to rotate around the first axis x. In the flip-type earphone charging case, the cover is adapted to rotate around the second axis relative to the case body. The second axis is parallel to or coincides with the first axis x. This design ensures that the bracket can accurately cover the rotation path of the cover when in the first position. Whether the cover is in the initial closed state or the half-open state, the bracket can effectively prevent it from continuing to open. When a herringbone support structure is formed in the second position, the parallel or coincident axes make the support angle between the bracket and the protective cover body (first housing) more uniform, and the force distribution on the support surface more reasonable. This avoids the support structure from "tilting" or "wobbling" due to the intersection of axes, improves the support stability of electronic devices (such as mobile phones and tablets), and reduces the risk of the device slipping.

[0013] Preferably, the first housing is provided with shafts on both sides, and the bushing and the shafts are adapted to rotate around the first axis x.

[0014] The outer peripheral wall of the shaft and the inner peripheral wall of the bushing are provided with a plurality of protrusions in one circumferential direction, and the outer peripheral wall of the shaft and the inner peripheral wall of the bushing are provided with a plurality of grooves in the other circumferential direction; the protrusions are adapted to be inserted into the grooves to realize the stepped angle adjustment of the bracket relative to the first housing, realize the stable fixation of the bracket in different positions (such as the first position, the second position), avoid angle deviation, and ensure the stability of the limiting and supporting functions.

[0015] Preferably, the number of protrusions is N, and the number of grooves is M, and Where k ≥ 1 and k is an integer, the minimum adjustment step α of the bracket is limited by the number of grooves M. .

[0016] Preferably, the device also includes a fastener, which axially engages with the shaft body to provide axial positioning for the bushing fitted onto the shaft body.

[0017] Preferably, the shaft body has a buckle groove, the fastener includes a buckle post and a buckle cap, the buckle post is adapted to be inserted into the buckle groove, the two sides of the first housing have a first stop surface, and the buckle cap includes a second stop surface. When the buckle post is engaged with the buckle groove, the first stop surface and the second stop surface respectively abut against the axial ends of the bushing to eliminate axial movement of the bushing and ensure the stability of the bracket when it rotates.

[0018] Preferably, the buckle post has a protruding strip that protrudes radially outward, the protruding strip is arranged parallel to the first axis x, and the inner peripheral wall of the buckle groove is formed with a guide groove suitable for the insertion of the protruding strip. The protruding strip and the guide groove are also suitable for circumferentially limiting the shaft and the fastener.

[0019] Preferably, the outer peripheral wall of the buckle post is provided with a first limiting convex arc, and the inner peripheral wall of the buckle groove is provided with a second limiting convex arc. The first limiting convex arc and the second limiting convex arc are adapted to engage along the first axis x-direction to prevent the buckle post from detaching from the buckle groove.

[0020] Preferably, the inner peripheral wall of the bushing is provided with an adjustment area protruding radially inward, and the end face of the adjustment area away from the first housing is formed with a third stop surface. The outer peripheral wall of the shaft is provided with a fourth stop surface, which is adapted to abut against the third stop surface, so as to achieve pre-limiting during the installation of the bushing on the shaft, simplify the assembly process, ensure the accurate installation position of the bushing, improve production efficiency, and avoid structural damage caused by over-installation.

[0021] The beneficial effects of this utility model are:

[0022] With its adjustable and rotatable bracket design, when the bracket is in the first position, it is positioned on the rotation path of the cover, effectively restricting the cover from opening and preventing accidental opening of the cover during the carrying of the charging case, thus avoiding the loss of the earphones and dust entering the charging case. The bracket can be rotated to the second position, forming a V-shaped support structure together with the protective case body, so that the protective case has the functions of protecting the earphone charging case and supporting electronic devices, improving the product's practicality and adaptability to different scenarios.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0033] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] like Figure 1As shown in Figure 7, an earphone charging case protective cover consists of a protective cover body 100 and a support 200. The flip-type earphone charging case includes a cover and a housing. The protective cover body 100 can be made of silicone or rigid PC material, and includes a first shell 101 and a second shell 102, which tightly cover the housing and cover of the charging case, respectively. Shafts 111 are integrally formed or fixedly provided on both sides of the first shell 101. The support 200 includes a support body 201 and bushings 202 disposed at both ends thereon. The support body 201 is generally arc-shaped to match the shape of the cover. The bushings 202 are fitted onto the shafts 111, allowing the support 200 to rotate around a first axis x of the shaft 111. The cover is adapted to rotate around a second axis relative to the housing, and the second axis is parallel to or coincides with the first axis x. N protrusions 112 are evenly distributed circumferentially on the outer peripheral wall of the shaft 111, and correspondingly, M grooves 221 are evenly distributed circumferentially on the inner peripheral wall of the bushing 202. The protrusions 112 and the grooves 221 are mutually compatible. When the user rotates the bracket 200, the protrusion 112 slides from one groove 221 into an adjacent groove 221, producing a "click" feel and holding the bracket 200 in its current position. Since the number of grooves 221 (M=12) is an integer multiple (k=2) of the number of protrusions (N=6), the minimum adjustment step, i.e. The bracket 200 allows for precise adjustment in 30° increments.

[0035] In this embodiment, when it is necessary to prevent the lid from opening, the bracket 200 is rotated to the first position. At this time, the bracket 200 is located on the rotation path of the lid to restrict the lid from opening. The bracket body 201 can prevent the lid from rotating upward and opening by forming a gap with the upper surface of the second housing 102. If the protective cover is placed on a horizontal plane, specifically by placing the protective cover on a horizontal plane through the first housing 101, this horizontal plane is defined as the reference plane. The orthographic projection of the bracket body 201 on the reference plane will at least partially overlap with the orthographic projection of the second housing 102 on the reference plane. Optimally, as shown in the figure, the bracket 200 is located directly above the lid / second housing 102, forming a physical barrier to prevent the lid from opening.

[0036] In this embodiment, when it is needed to be used as a mobile phone stand 200, the stand 200 is rotated to the second position so that it is spread at a certain angle with the protective case body 100, for example, 120°, to form a stable V-shaped support structure. The front / back of the protective case body 100 is adapted to form a support slope for supporting electronic products such as mobile phones.

[0037] In this embodiment, a fastener 300 is provided to ensure that the bracket 200 does not axially detach from the shaft 111. A fastening groove 113 is formed at the end of the shaft 111. The fastener 300 includes a fastening post 301 and a fastening cap 302. During assembly, the bushing 202 is first fitted onto the shaft 111, and then the fastening post 301 of the fastener 300 is inserted into the fastening groove 113 of the shaft 111 along the extension direction of the first axis x. First stop surfaces 114 are formed on both sides of the first housing 101, and a second stop surface 321 is provided on the fastening cap 302. After assembly, the first stop surfaces 114 and the second stop surfaces 321 tightly abut against the two end faces of the bushing 202 from both sides, achieving axial locking.

[0038] In this embodiment, the fastener 301 has a radially outwardly protruding rib 311, which is parallel to the first axis x. The inner peripheral wall of the fastening groove 113 has a guide groove 115 suitable for the insertion of the rib 311. The guide groove 115 is suitable for assisting the quick alignment of the shaft 111 and the fastener 300 during assembly. Furthermore, the cooperation between the rib 311 and the guide groove 115 is also suitable for circumferentially limiting the shaft 111 and the fastener, preventing relative rotation between the fastener 300 and the shaft 111. A first limiting arc 312 is provided on the outer periphery of the fastener 301, and a second limiting arc 116 is provided on the inner wall of the fastening groove 113. The two are engaged along the extension direction of the first axis x to prevent the fastener 300 from falling off.

[0039] In this embodiment, the inner wall of the bushing 202 is provided with an adjustment area 222, which has a groove 221. The end face of the adjustment area 222 away from the first stop surface 114 forms a third stop surface 223, and a fourth stop surface 117 is provided on the outer wall of the shaft body 111. During the installation of the bushing 202, when the fourth stop surface 117 abuts against the third stop surface 223, a significant resistance will be generated, indicating that the bushing 202 has been initially installed in place, facilitating the subsequent pressing in of the fastener 300.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
