Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset accessories technology, and in particular to a protective structure for the buttons of a sliding Bluetooth headset. Background Technology

[0002] Bluetooth headsets, as portable audio devices, are widely used in daily life. Traditional Bluetooth headsets typically include a charging case and one or more earbuds for storage and charging. In order to achieve a slim and lightweight design and ease of operation, the earbuds have buttons on them to control playback, calls, and other functions. These buttons are usually exposed on the outer surface of the earbuds and lack effective structural protection. When the earbuds are carried, they are easily damaged by friction, pressure, or accidental drops from other items in pockets. This can lead to physical damage or accidental activation of the functions, affecting the normal lifespan of the earbuds and the user experience.

[0003] Meanwhile, the charging case of Bluetooth earphones, as a storage container, relies mainly on simple magnetic or snap-locking structures for its lid to close. These simple locking structures may accidentally open when subjected to external vibration or pressure, causing the earphones inside to fall out or be lost, resulting in inconvenience and property loss for users. In the existing technology, there is a lack of an integrated solution that is structurally reliable, easy to operate, and can effectively protect the earphone buttons and securely lock the charging case to ensure the safety of Bluetooth earphones when not in use.

[0004] Therefore, this utility model proposes a sliding Bluetooth headset button protection structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, Bluetooth headset buttons are usually exposed and lack effective physical protection, making them easy to be damaged by collisions or accidentally touched. In addition, the locking structure of the charging case is relatively simple and unreliable, which can easily lead to accidental opening and loss of the headset during carrying. The present invention aims to provide a sliding Bluetooth headset button protection structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a sliding Bluetooth headset button protection structure, including a body and a charging case for housing the body. The earphone head is fixedly connected to the top surface of the body, and a locking mechanism is provided on the front side of the charging case.

A return spring is fixedly connected to the right side of the locking block, and the locking block slides into the inner wall of the sliding groove inside the charging case. One end of the return spring is fixedly connected to the locking block, and the other end abuts against the inner wall of the sliding groove. The locking block can be locked into the slot by the elastic force of the return spring to lock the charging case.

[0008] Furthermore, a connecting rod is fixedly connected to the bottom of the machine body, and the operating block is fixedly connected to the top of the connecting rod. The front side of the operating block has an installation groove and a buffer groove in the middle.

[0009] Preferably, the locking mechanism forms a sliding guide engagement between the locking block and the sliding groove. The locking block is constructed in an L-shape or rectangular shape. The return spring is in a compressed state or a naturally extended state to drive the locking block to reciprocate along the length direction of the sliding groove, thereby realizing the engagement and disengagement of the locking block and the locking groove.

[0010] Preferably, the front of the earphone head has a sound hole, and the dustproof pad is fixedly connected to the inner wall of the sound hole by adhesive or snap-fit. The dustproof pad covers the opening section of the sound hole and is made of a mesh or porous material to prevent external dust from entering the sound hole while maintaining sound penetration.

[0011] Preferably, memory foam is fixedly installed on both the upper and lower ends of the inner wall of the charging case. The shape of the memory foam is adapted to the outer contour of the device body. When the device body is placed inside the charging case, the outer surface of the device body is tightly fitted with the memory foam, and the elastic deformation of the memory foam is used to wrap and cushion the device body.

[0012] Preferably, the operating block is a rectangular block structure, with the mounting groove surrounding the outer periphery of the buffer groove, or the mounting groove located on both sides of the buffer groove. The material hardness of the protective pad is greater than that of the buffer pad. The protective pad is used to withstand external impact force, and the buffer pad is used to absorb excess travel and vibration when the button is pressed.

[0013] Preferably, the connecting rod is vertically fixed to the center of the bottom surface of the device body. The connecting rod supports the operation block under the device body, so that the buttons on the operation block and the earphone head on the device body are arranged vertically, which makes it convenient for the user to operate the buttons when holding the device body.

[0014] Preferably, the outer surface of the slider is provided with anti-slip texture or protrusions, the sliding stroke of the slider in the slide groove is limited by the inner walls of both ends of the slide groove, and the slider is fixedly connected to the locking block located inside the charging box through the connecting post passing through the slide groove, thereby realizing the control of the internal locking mechanism from the outside of the charging box.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0021] Please refer to Figures 1 to 5 This utility model provides a sliding Bluetooth headset button protection structure, which aims to solve the structural defects in the prior art, such as the lack of physical protection for Bluetooth headset buttons, which makes them easy to be accidentally touched and damaged, the easy accumulation of dust in the ear slot 4, and the unreliable locking mechanism of the charging case 201, which leads to the accidental drop of the headset.

[0022] Please refer to Figure 1 and Figure 4 The sliding Bluetooth headset button protection structure includes a body 1 and a charging case 201 for storing the body 1. The charging case 201 serves as the outer protective shell of the body 1 and has memory foam 206 inside for cushioning and shock absorption. The front side wall of the charging case 201 integrates a locking mechanism 2 for locking and unlocking the lid. Through the cooperation of the body 1 and the charging case 201, a complete protection system integrating dustproof, dropproof and accidental touch prevention is constructed.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3The front wall of the charging case 201 has a sliding groove 208. A sliding button 204 is slidably engaged with the inner wall of the sliding groove 208 in a reciprocating manner. The rear side of the sliding button 204 extends through the sliding groove 208 into the interior of the charging case 201 and is fixedly connected to a locking block 205. The locking block 205 is confined within a sliding groove 203 formed in the internal structure of the charging case 201. The outer wall of the locking block 205 is tightly fitted with the inner wall of the sliding groove 203 to form a sliding guide relationship. A return spring 202 is horizontally disposed within the sliding groove 203, and one end of the return spring 202 is fixedly engaged with the inner wall of the sliding groove 203. The right side wall of the locking block 205 is fixedly connected to the locking block 205. The other end of the return spring 202 abuts against the right inner wall of the sliding groove 203. The top of the inner wall of the charging box 201 is provided with a slot 207 corresponding to the movement trajectory position of the locking block 205. The sliding button 204, the locking block 205, the return spring 202, the sliding groove 203 and the slot 207 together form the locking mechanism 2. The sliding button 204 drives the locking block 205 to move and compress or release the return spring 202, so as to realize the locking or separation of the locking block 205 and the slot 207, thereby controlling the locking state of the charging box 201.

[0024] Please refer to Figure 4 and Figure 5 The top surface of the body 1 is fixedly connected to the earphone head 3 by integral molding or welding. The front side of the earphone head 3 has a sound channel 4 for sound conduction. The dustproof pad 11 is fixedly installed on the inner wall of the sound channel 4 by adhesive or interference fit. The dustproof pad 11 completely covers the opening area of ​​the sound channel 4 to prevent external dust from entering. The bottom center of the body 1 extends vertically downward and is fixedly connected to the connecting rod 9. The top end of the connecting rod 9 is fixedly connected to the rectangular structural operation block 12. The front surface of the operation block 12 has a mounting groove 5 for accommodating protective components and a buffer groove 10 located in the area of ​​the mounting groove 5. The protective pad 6 is embedded in the inner wall of the mounting groove 5. The buffer pad 8 is filled and fixed to the inner wall of the buffer groove 10. The button 7 is set on the front surface of the buffer pad 8 and partially embedded therein. The thickness of the protective pad 6 is greater than or equal to the height of the button 7 protruding from the surface of the operation block 12, thereby forming an embedded buffer protection structure for the button 7 on the front of the operation block 12.

[0025] Please refer to Figure 1 , Figure 3 and Figure 4The earphone head 3 is located at the top of the body 1 and has a streamlined structure that conforms to the physiological characteristics of the human ear. The center of the front side has a listening slot 4 with a circular or elliptical inner wall structure. The listening slot 4 is the outlet channel for sound to be transmitted from the inside of the earphone to the outside. A dustproof pad 11 is fixedly connected to the inner wall of the listening slot 4 by adhesive or snap-fit. The dustproof pad 11 is made of a mesh or porous material with high acoustic permeability. The size and shape of the dustproof pad 11 are adapted to the opening cross section of the listening slot 4. The dustproof pad 11 is firmly installed on the inner wall of the listening slot 4, which can prevent dust and fine particles in the external environment from entering the interior of the listening slot 4, thereby avoiding blockage of the sound unit and ensuring that the sound quality of the earphone is not affected.

[0026] A connecting rod 9 is vertically fixed to the center of the bottom surface of the body 1. The connecting rod 9 has a cylindrical or polygonal rod structure. The length of the connecting rod 9 is designed so that the operating block 12 is located in a suitable operating position below the body 1. The operating block 12 is fixedly connected to the top end of the connecting rod 9. The operating block 12 is a regular rectangular block structure and can serve as a mounting base for the button 7 and protective components. The front surface of the operating block 12 is provided with a mounting groove 5 and a buffer groove 10. The buffer groove 10 is located at the center of the operating block 12, and the mounting groove 5 is arranged around the outer periphery of the buffer groove 10. In the assembled state, the protective pad 6 is embedded in the inner wall of the mounting groove 5, and the buffer pad 8 is filled and fixed in the inner wall of the buffer groove 10. The button 7 is partially embedded in the front surface of the buffer pad 8. This hard-outer-soft-inner-embedded protective structure ensures that when the button 7 is subjected to external impact, the protective pad 6 can first bear the main physical protection, and then the buffer pad 8 can provide flexible cushioning and shock absorption.

[0027] When the slider 204 is slid into place, the return spring 202 is fully compressed. When the slider 204 is released, the elastic force of the return spring 202 serves as the sole power source, automatically pushing the card block 205 into the card slot 207, thus locking the charging box 201 and achieving the convenient effect of single operation and automatic locking.

[0028] As a preferred embodiment, in order to ensure the stability and reliability of the locking mechanism 2, the locking block 205 and the sliding groove 203 form a sliding fit. The locking block 205 can adopt an L-shaped or rectangular structure. The thickness of the locking block 205 is precisely matched with the width of the sliding groove 203 to ensure that the lateral gap is minimal during the sliding process. At the same time, the return spring 202 is designed to maintain a certain pre-compression state when the sliding button 204 is in the unlocked position or to be in a naturally extended state in the locked state, so as to ensure that the return spring 202 can continuously drive the locking block 205 to reciprocate stably along the length direction of the sliding groove 203, thereby accurately locking into the slot 207 to achieve stable locking.

[0029] As another preferred embodiment, in order to enhance the shock protection of the earphones inside the charging case 201, memory foam 206 is fixedly installed at the upper and lower ends of the inner wall of the charging case 201. The shape and thickness of the memory foam 206 are designed to match the outer contour of the body 1. When the body 1 is placed inside the charging case 201, the memory foam 206 can closely fit the outer surface of the body 1. Utilizing the low density and high elasticity of the memory foam 206 itself, when the earphones are subjected to external impact or vibration, it can wrap and cushion the body 1 in all directions, effectively absorb kinetic energy, and prevent the body 1 from shaking inside the case, causing wear or damage.

[0030] In another preferred embodiment, to improve the protection level and operating feel of the button assembly, the protective pad 6 and the buffer pad 8 have a significant difference in material hardness. The protective pad 6 is preferably made of a plastic material with a harder hardness than the buffer pad 8, which can withstand external hard impact forces. The buffer pad 8 is made of a soft rubber or silicone material with high elasticity and low modulus. The button 7 is partially embedded in the front surface of the buffer pad 8. The buffer pad 8 is used to absorb the excess travel and operating vibration when the button 7 is pressed, providing a soft feedback. At the same time, the connecting rod 9 supports the operating block 12 under the body 1, so that the button 7 on the operating block 12 and the earphone head 3 on the body 1 are in a vertical spatial relationship, completely avoiding mutual interference between the earphone head 3 and the button 7, which facilitates precise operation by the user.

[0031] As another preferred embodiment, in order to enhance the operating friction and feel of the slider 204, the outer surface of the slider 204 may be provided with anti-slip texture or multiple protrusions. The sliding stroke length of the slider 204 in the slide groove 208 is physically limited by the inner walls of both ends of the slide groove 208. The slider 204 is connected to the locking block 205 located inside the charging box 201 by injection molding or thread fixing. This structure allows the user to directly and stably push and pull the internal locking mechanism 2 from the outside of the charging box 201.

[0032] As another preferred embodiment, in order to ensure the normal function of button 7 and the design of the protective structure, the depth of the buffer groove 10 is greater than or equal to the thickness of the buffer pad 8, ensuring that the buffer pad 8 has enough space to deform within the buffer groove 10. Button 7 is fixedly installed on the front surface of the buffer pad 8. All protective components such as dustproof pad 11, protective pad 6, buffer pad 8 and memory foam 206 are designed to cooperate with each other to jointly construct a multi-layered and all-round protective system for the body 1 and button 7.

[0033] Working principle: When the user uses the device 1, the earphone head 3 on the top surface of the device 1 outputs sound through the ear slot 4. Since the dustproof pad 11 is fixedly connected to the inner wall of the ear slot 4, the dustproof pad 11 can completely cover the opening section of the ear slot 4. Utilizing its own mesh or porous structure, it effectively prevents dust or fine particles in the environment from entering the interior of the ear slot 4, thereby ensuring stable output of headphone sound quality and avoiding sound degradation caused by dust accumulation. The bottom surface of the device 1 has a connecting rod 9 fixedly connected to an operation block 12. The mounting slot 5 on the front side of the operation block 12 is fixedly installed with a protective pad 6, and the buffer slot 10 is fixedly installed with a buffer pad 8. Button 7... Located on the front side of the buffer pad 8, if an external hard object accidentally comes into contact with the button area during normal use or when the headphones are placed in or taken out, the protective pad 6 will be the first to contact the external impact force. The structure protruding from the surface of the operating block 12 forms the first physical isolation and protection for the button 7, preventing the button 7 from being directly pressed or damaged. When the user needs to press the button 7 to operate, the button 7 will press the buffer pad 8 inward. The elastic deformation of the buffer pad 8 absorbs the pressing stroke and vibration, providing the user with a soft feedback. At the same time, the operating block 12 separates the button 7 and the headphone head 3 at the upper and lower ends of the body 1, avoiding mutual interference. After the device 1 is placed inside the charging case 201, it needs to be locked. The user operates the locking mechanism 2 by sliding the external slider 204 backward. The slider 204, through the fixedly connected locking block 205, pushes the locking block 205 backward along the guide direction of the sliding groove 203. During the movement, the locking block 205 compresses the return spring 202 to a pre-compressed state, causing the locking block 205 to temporarily disengage from the engaging position of the slot 207. At this time, the lid of the charging case 201 can be closed. Once the lid is closed, the user releases the slider 204, and the return spring 202 immediately releases and stores. The elastic potential energy pushes the locking block 205 forward. Driven by the return spring 202, the locking block 205 moves forward along the guide of the sliding groove 203 to reset. Finally, the front end of the locking block 205 is fully engaged in the slot 207 at the top of the charging case 201, thereby achieving a reliable mechanical lock on the charging case 201. This effectively prevents the charging case 201 from being accidentally opened in a closed environment such as a pocket, thus avoiding the risk of the device 1 falling out, being damaged, or being lost. In addition, the memory foam 206 placed at the top and bottom of the charging case 201 provides additional shock-absorbing protection by adhering to the outer surface of the device 1.
