[0001] The present invention relates to a leather case, and in particular to a leather case structure for a Bluetooth headset charging compartment. Background Art

[0002] At present, the open-type Bluetooth headsets on the market that use leather materials for the charging case are usually a combined leather case structure.

[0003] This leather case structure is composed of multiple parts, usually a hard plastic or metal frame at the bottom combined with an external leather case. The frame can provide certain support and protection, and the leather case covers the surface of the frame to increase the aesthetics and feel.

[0004] This leather case structure has the following problems:

[0005] 1. Increased weight: The addition of hard plastic or metal frames will increase the overall weight of the leather case, and users will feel uncomfortable when using such leather cases.

[0006] 2. Reduced flexibility: A hard frame may limit the deformation ability of the holster, resulting in poor flexibility of the holster.

[0007] 3. Risk of damage: Although hard frames can provide better protection, if they are subjected to strong external impact or dropped, hard plastic or metal frames may be damaged such as cracking and deformation, and are relatively difficult to repair.

[0008] 4. Appearance texture: Although the exterior is covered with a leather case, the presence of the hard frame may affect the overall soft texture and fit to a certain extent. Summary of the Invention

[0009] The purpose of the present invention is to provide a leather case structure for a Bluetooth headset charging compartment to solve the technical problems existing in the prior art.

[0010] According to one aspect of the present invention, a leather case structure for a Bluetooth headset charging case is provided, comprising an outer layer, a PC layer, a filling layer and an inner layer arranged in sequence from the outside to the inside, the outer layer is a PU leather material, the inner layer is a suede leather material, and a decorative piece is also provided on the outer layer, which is fixed on one end of the upper surface of the outer layer.

[0011] In some embodiments, an inner wrapping structure is formed on the lower surface of the outer layer, and the inner wrapping structure can wrap the outer circle of the PC layer and the filling layer.

[0012] In some embodiments, a PC sheet is further included. The PC sheet is disposed between the filling layer and the inner surface layer, and the filling layer can cover the outer circle of the PC sheet.

[0013] In some embodiments, screws are further included, and a steel sheet is provided in the gap. The steel sheet is located below the PC layer. One end of the screw passes through the steel sheet, the PC layer and the outer layer in sequence, and the end of the screw passing through the outer layer is connected to the decorative sheet.

[0014] In some embodiments, magnets are further included, and receiving holes are provided on the outer layer, the PC layer, the decorative sheet and the steel sheet, and the magnets are provided in the receiving holes.

[0015] In some embodiments, there are three magnets and three receiving holes, and the three magnets are distributed in the three receiving holes in sequence.

[0016] In some embodiments, circular holes are provided at corresponding positions of the PC sheet and the filling layer, and Hall magnets are provided in the circular holes.

[0021] 2. Reduce noise: PU leather is a soft leather. During use, when the outer layer of the PU leather material contacts and rubs against other objects, the noise generated is relatively small, which can provide a quieter use environment. When designing the leather case earphone charging case, the applicant also fully considered and solved the following problems:

[0022] (1) Aluminum alloy metal parts are added as decorative pieces on the outer PU leather, and are fixed to the outer PU leather by reliable screw connections. The screws and steel sheets for fixing the decorative pieces are hidden in the outer PU leather, making the overall appearance beautiful.

[0023] The added PC layer serves two main purposes: reducing the overall softness of the leather case and concealing the small step on the outer surface where the internal structure is visible. The PC layer also slightly increases the hardness of the case and allows it to have a curved shape when not under load, allowing the headphone compartment cover to remain at a fixed angle when open. It also acts as a shielding layer, concealing any traces of the internal structure left by the outer PU leather.

[0024] The present invention is connected to the charging compartment and opened and closed by magnets. A metal plate is provided on the back to connect with the magnets of the compartment, achieving the replaceable effect of the present invention.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Figures 1 to 4 The diagram schematically shows the leather case structure of a Bluetooth headset charging compartment according to an embodiment of the present invention.

[0033] like Figures 1 to 4 As shown, a leather case structure of a Bluetooth headset charging case includes: Figure 2 The outer layer 1, PC layer 2, filling layer 3 and inner layer 4 are arranged in sequence from top to bottom. The outer layer 1 is made of PU leather material, and the inner layer 4 is made of suede leather material. A decorative piece 5 can also be installed on the outer layer 1. The decorative piece 5 is fixed to one end of the upper surface of the outer layer 1. Figure 1 As can be seen in the figure, the decorative sheet 5 not only serves a decorative purpose but also increases the thickness of the lower end of the leather case of the present invention. Thus, when the leather case is mounted on the Bluetooth headset compartment, the user can push and rotate the leather case via the decorative sheet 5 when opening it, making the opening process more convenient and quick. In addition, the outer layer 1 of the present invention can wrap around the PC layer 2 and the filling layer 3.

[0034] In this embodiment, if Figures 1 to 3 As shown, the lower surface of the outer layer 1 is formed with an inner packaging structure 11, and the inner packaging structure 11 is formed by wrapping the PC layer 2 and the filling layer 3 on the lower surface of the outer layer 1. Therefore, the outer layer 1 can cover the outer circle of the PC layer 2 and the filling layer 3. That is to say, the inner packaging structure 11 of the outer layer 1 can wrap the outer circle of the PC layer 2 and the filling layer 3, and then cover the inner packaging structure 11 with the PU leather material of the outer layer. The PC layer 2 can reduce the overall softness of the leather case of the present invention and block the small steps of the internal structure (such as the outer circle of the inner packaging structure 11) exposed on the outer surface. The PC layer 2 slightly increases the hardness and makes the present invention have an arc shape when not under force, so that the earphone compartment flip cover is at a fixed angle when open and not under force. It can act as a shielding layer to conceal the traces of the internal structure produced by the outer PU leather.

[0035] In this embodiment, a PC sheet 6 is also included. The PC sheet 6 is installed between the filling layer 3 and the inner layer 4. The filling layer 3 can cover the outer circle of the PC sheet 6. For example, a receiving groove can be formed on the back of the filling layer 3, and the PC sheet 6 is placed in the receiving groove. The length of the PC sheet 6 in this embodiment is about one-third of the length of the filling layer 3. When the leather case of the present invention is installed on the earphone compartment, Figure 1 The right end of the earphone compartment is connected to the front of the earphone compartment of the present invention. When the leather case is opened, the user will Figure 1 Therefore, by providing the PC sheet 6, the hardness of the leather case of the present invention can be further enhanced.

[0036] The present invention also includes screws 7. A steel sheet 121 is provided in the gap 12. The steel sheet 121 is located below the PC layer 2. One end of the screw 7 passes through the steel sheet 121, the PC layer 2, and the outer layer 1 in sequence. The end that passes through the outer layer 1 is connected to the decorative sheet 5. By providing screws 7, the steel sheet 121, the PC layer 2, and the outer layer 1 can be connected into a whole, making the overall structure more compact.

[0037] from Figure 2As can be seen in the figure, this embodiment also includes a magnet 81. The outer layer 1, PC layer 2, filling layer 3 and steel sheet are all integrally formed with a receiving hole 8, and the magnet 81 can be installed in the receiving hole 8. When the leather case of the present invention is installed on the earphone compartment, the magnet 81 can be adsorbed together with the front surface of the earphone compartment, achieving a magnetic attraction effect.

[0038] In this embodiment, there are three magnets 81 and three receiving holes 8, and the three magnets 81 are sequentially distributed in the three receiving holes 8. In other embodiments, the number and position of the magnets 81 and the receiving holes 8 can be set according to actual conditions, such as the number of the magnets 81 and the receiving holes 8 can be five or three.

[0039] In this embodiment, circular holes 230 are integrally formed at corresponding positions of the PC sheet 6 and the filling layer 3, and a Hall magnet 9 is installed in the circular hole 230. The Hall magnet 9 can interact with the Hall sensor on the earphone.

[0040] like Figure 2 As shown, there are two circular holes 230 in this embodiment, and a Hall magnet 9 is installed in each circular hole 230. In other embodiments, the number of circular holes 230 and Hall magnets 9 can also be three, and a Hall magnet 9 is provided in each of the three circular holes 230.

[0041] like Figure 2 As shown, the present invention further includes a metal sheet 10, one end of the inner layer 4 is integrally formed with three through holes, and the metal sheet 10 is provided with three protrusions 100, which protrude downward (therefore, Figure 2 The other side of the convex portion shown in the figure), the metal sheet 10 is arranged between the filling layer 3 and the inner layer 4, and the three convex portions 100 of the metal sheet 10 extend out of the through hole. The three convex portions 100 can be adsorbed on the earphone compartment, and the three convex portions 100 of the metal sheet can be connected to the magnet of the compartment body, so as to achieve the replaceable effect of the present invention.

[0042] Since the outer layer is made of PU leather material, the PU leather material is soft and can better show the texture of the leather itself, giving the user a sense of high-end and exquisiteness. The present invention can also reduce noise: the PU leather material is soft leather. During use, when the outer layer of the PU leather material contacts and rubs against other objects, the noise generated is relatively small, which can provide a quieter use environment. When designing the leather case earphone charging compartment, the applicant also fully considered and solved the following problems:

[0043] (1) Aluminum alloy metal parts are added as decorative pieces on the outer PU leather, and are fixed to the outer PU leather by reliable screw connections. The screws and steel sheets for fixing the decorative pieces are hidden in the outer PU leather, making the overall appearance beautiful.

[0044] The added PC layer has two main functions: reducing the overall softness of the outer PU leather and concealing the small steps on the outer surface where the internal structure is exposed. The PC layer slightly increases hardness and gives the invention a curved shape when not under load, allowing the earphone compartment flip cover to remain at a fixed angle when open without force. It also acts as a shielding layer to conceal the traces of internal structure left by the outer PU leather.

[0045] The present invention is connected to the charging compartment and opened and closed by magnets. A metal plate is provided on the back to connect with the magnets of the compartment, which can achieve the effect of the present invention being replaceable. Three magnets are used to open and close the cover of the earphone compartment. The present invention also has two cylindrical magnets for mutual induction with the Hall effect on the earphones.

[0046] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
