Description

Technical Field

[0001] This utility model relates to the field of Bluetooth earphone charging cases, specifically a Bluetooth earphone charging case. Background Technology

[0002] The Bluetooth earphone charging case can charge the Bluetooth earphones. After using the Bluetooth earphones, users can directly connect them to a power source to charge them. However, because the internal battery of Bluetooth earphones is relatively large, the amount of power stored is relatively small, which results in a short continuous working time for Bluetooth earphones. The charging case allows Bluetooth earphones to be charged anytime, anywhere, alleviating the problem of short battery life.

[0003] Currently, there are many types of Bluetooth earphone charging cases. These cases typically have an internal socket for charging Bluetooth earphones and an external charging port. For convenience, people usually carry the charging case with them, often placing it in their pocket or bag. However, when running or engaging in other outdoor activities, the charging case may slip out of the pocket and fall to the ground. Furthermore, since the charging case lacks a secondary locking mechanism, it often causes the earphones inside to fall out and become damaged. Therefore, this paper proposes a new Bluetooth earphone charging case to address these issues. Utility Model Content

[0004] To address the problem of existing charging cases that slip out of pockets during movement and fall to the ground, causing damage to the earphones, this invention proposes a Bluetooth earphone charging case.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a Bluetooth earphone charging case, including an earphone case and a charging port. The earphone case includes an upper cover and a lower cover. Both the upper cover and the lower cover are fixedly connected to a connecting block. Both connecting blocks are rotatably connected to an inner cover through a rotating shaft. An inner compartment is fixedly connected to the inner side of the inner cover. The inner compartment is installed inside the earphone case. The charging port is installed on the side of the inner compartment.

[0006] Preferably, the side of the upper cover away from the locking assembly is fixedly connected to an upward push block by a fixing bolt, and the side of the lower cover away from the locking assembly is fixedly connected to a downward push block by a fixing bolt. The downward push block and the upward push block are engaged by a locking assembly.

[0007] Preferably, the locking assembly includes a fixed base, which is fixedly connected to the upper push block. A slide rod is slidably sleeved on the middle of the fixed base, and a fixed plate is fixedly connected to the middle of the slide rod. A fixed ring is slidably sleeved on the lower side of the slide rod, and the fixed ring is fixedly connected to the fixed base. The fixed ring is located below the fixed plate, and a compression spring is provided between the fixed ring and the fixed plate. A limit ring is fixedly connected to the lower side of the slide rod, and the limit ring is located below the fixed ring. A limit sleeve is slidably connected to the lower side of the slide rod, and the limit sleeve is located below the fixed ring. A retaining sleeve is fixedly connected to the bottom of the slide rod, and the retaining sleeve engages with the lower push block.

[0008] Preferably, the locking assembly further includes a plurality of annularly distributed protrusions, which are slidably sleeved with the push block. A movable rod is fixedly connected to one side of the protrusion, and the movable rod is slidably connected to the push block. A spring is provided on the outer side of the movable rod.

[0009] Preferably, the upper side of the protrusion is provided with an inclined surface.

[0010] Preferably, both the limiting sleeve and the card sleeve are conical in shape, and the limiting sleeve and the card sleeve are the same size but opposite in direction.

[0011] Preferably, the inner compartment cover has two sets of mounting columns installed on the side near the inner compartment. Each set of mounting columns is threaded with a tightening bolt. An upper clamping plate and a lower clamping plate are engaged between the tightening bolt and the mounting column. Two sets of rotating shafts are rotatably connected between the two sets of upper and lower clamping plates.

[0012] Preferably, a Bluetooth headset is provided on the side of the inner compartment away from the inner compartment cover.

[0013] Preferably, the inner compartment cover has a groove that matches the connecting block.

[0014] Preferably, an electromagnet matching the upper push block is installed on the side of the lower push block near the upper push block.

[0015] The advantages of this utility model are:

[0016] 1. This utility model, through the structural design of the locking assembly, allows for easy access to outdoor activities. When the user needs to press down the sliding rod on the upper push block, a light press causes the rod to move downwards, moving the fixing plate and the retaining sleeve downwards. Due to friction between the limiting sleeve and the fixing seat, the limiting sleeve does not move downwards. After the retaining sleeve moves downwards and inserts into the lower push block, it compresses the protrusions, causing multiple protrusions to move outwards until the retaining sleeve is fully inside the lower push block. At this point, the protrusions move inwards until the retaining sleeve is locked, forming a secondary lock. The retaining sleeve is locked without touching the sliding rod. The earphone case cannot be pulled out from inside the push block. When you need to use the earphone case, you can press the slide bar deeply with your hand. At this time, the limiting sleeve on the slide bar will be limited by the limiting ring and move downward. Then the limiting sleeve will be fully inserted into the protrusion. Then release the slide bar. At this time, the limiting sleeve will be moved upward by the spring force. The resistance of the protrusion will not be able to follow the slide bar to move upward until the retainer touches the limiting sleeve. At this time, the protrusion will not be able to hold the retainer. Then the limiting sleeve and the retainer will move upward with the slide bar to complete the unlocking. To lock it again, repeat the above operation to prevent the earphone case from falling out and damaging the earphones.

[0017] 2. This utility model, through the structural design of the upper and lower covers, allows for the following steps during use: First, open the upper and lower covers, place the Bluetooth earphones into the charging port of the inner compartment for charging, and then rotate the lower and upper push blocks with both hands. At this time, the lower and upper push blocks drive the upper and lower covers to rotate around the pivot axis, opening the earphone compartment. Then, by rotating the upper and lower covers, the earphone compartment is closed by the attraction of the lower and upper push blocks. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0031] This application discloses a Bluetooth headset charging case. (See also...) Figure 1 , Figure 2 and Figure 3 A Bluetooth earphone charging case includes an earphone compartment 1 and a charging port 2. The earphone compartment 1 includes an upper cover 101 and a lower cover 103. Both the upper cover 101 and the lower cover 103 are fixedly connected to a connecting block 102. Both connecting blocks 102 are rotatably connected to an inner cover 5 via a pivot 108. An inner compartment 3 is fixedly connected to the inside of the inner cover 5. The inner compartment 3 is installed inside the earphone compartment 1. The charging port 2 is installed on the side of the inner compartment 3.

[0032] The Bluetooth earphone 4 can be charged. When using it, first open the top cover 101 and the bottom cover 103, put the Bluetooth earphone 4 into the charging port of the inner case 3 for charging, and then close the earphone case 1 by rotating the top cover 101 and the bottom cover 103. When you need to go out for sports, you can lock the earphone case 1 again by using the locking component 6 to prevent the earphone case 1 from falling and causing the earphone to be damaged.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 8 The upper cover 101 is fixedly connected to the side away from the locking assembly 6 by a fixing bolt 111 with an upper push block 105. The lower cover 103 is fixedly connected to the side away from the locking assembly 6 by a lower push block 104 by a fixing bolt 111. The lower push block 104 and the upper push block 105 are engaged by the locking assembly 6. The lower push block 104 and the upper push block 105 facilitate the rotation of the upper cover 101 and the lower cover 103. The lower push block 104 and the upper push block 105 have protruding parts on opposite sides. The upper cover 101 and the lower cover 103 can be easily rotated by pressing the protruding parts of the lower push block 104 and the upper push block 105 with both hands.

[0034] Reference Figure 4 , Figure 6 and Figure 7 The locking assembly 6 includes a fixed base 601, which is fixedly connected to the upper push block 105. A slide rod 602 is slidably sleeved in the middle of the fixed base 601. A fixed plate 603 is fixedly connected in the middle of the slide rod 602. A fixed ring 605 is slidably sleeved on the lower side of the slide rod 602. The fixed ring 605 is fixedly connected to the fixed base 601 and is located below the fixed plate 603. A compression spring 604 is provided between the fixed ring 605 and the fixed plate 603. A limit ring 608 is fixedly connected to the lower side of the slide rod 602 and is located below the fixed ring 605. A limit sleeve 606 is slidably connected to the lower side of the slide rod 602 and is located below the fixed ring 605. A retaining sleeve 607 is fixedly connected to the bottom of the slide rod 602 and is engaged with the lower push block 104.

[0035] When you need to go out for exercise and put the earphone compartment 1 in your pocket, you can press down the slider 602 on the push block 105. Pressing the slider 602 lightly moves it downwards, causing the fixing plate 603 and the retaining sleeve 607 to move downwards. Due to friction between the limiting sleeve 606 and the fixing base 601, the limiting sleeve 606 does not move downwards. After the retaining sleeve 607 moves downwards and inserts into the push block 104, it squeezes the protrusion 611, causing multiple protrusions 611 to move outwards until the retaining sleeve 607 is completely inside the push block 104. At this point, the protrusions 611 move inwards until the retaining sleeve 607 is locked, forming a secondary lock. Without touching the slider 602, the retaining sleeve 607... If the earphone compartment 1 is stuck inside the push block 104 and cannot be pulled out, you can press the slide bar 602 deeply by hand when you need to use the earphone compartment 1. At this time, the limiting sleeve 606 on the slide bar 602 is limited by the limiting ring 608 and moves downward. Then the limiting sleeve 606 moves completely into the protrusion 611. Then release the slide bar 602. At this time, the limiting sleeve 606 moves upward by the elastic force of the compression spring 604. The resistance of the protrusion 611 cannot follow the slide bar 602 to move upward until the retaining sleeve 607 touches the limiting sleeve 606. At this time, the protrusion 611 cannot hold the retaining sleeve 607. Then the limiting sleeve 606 and the retaining sleeve 607 move upward with the slide bar 602 to complete the unlocking. To lock again, repeat the above operation.

[0036] Reference Figure 4 and Figure 6 The locking assembly 6 also includes a plurality of annularly distributed protrusions 611, which are slidably sleeved with the push block 104. A moving rod 609 is fixedly connected to one side of the protrusion 611, which is slidably connected to the push block 104. A spring 610 is provided on the outer side of the moving rod 609.

[0037] Reference Figure 6 The upper side of the protrusion 611 is provided with an inclined surface;

[0038] Reference Figure 9 The limiting sleeve 606 and the ferrule 607 are both conical in shape and structure, and the size of the limiting sleeve 606 and the ferrule 607 are opposite in the same conical direction.

[0039] Reference Figure 5 and Figure 8 Two sets of mounting columns 109 are installed on the side of the inner compartment cover 5 near the inner compartment 3. Both sets of mounting columns 109 are threaded with tightening bolts 110. An upper clamping plate 106 and a lower clamping plate 107 are engaged between the tightening bolts 110 and the mounting columns 109. Two sets of rotating shafts 108 are rotatably sleeved between the two sets of upper clamping plates 106 and lower clamping plates 107.

[0040] When it is necessary to open the earphone compartment 1, the lower push block 104 and the upper push block 105 can be rotated with both hands, provided that the locking assembly 6 is not locked again. At this time, the lower push block 104 and the upper push block 105 drive the upper cover 101 and the lower cover 103 to rotate around the pivot 108. The upper clamping plate 106 and the lower clamping plate 107 rotate and install the two sets of pivots 108 on the lower clamping plate 107 and the upper clamping plate 106, preventing the pivots 108 from falling off. The mounting post 109 and the tightening bolt 110 facilitate the installation and fixation of the upper clamping plate 106 and the lower clamping plate 107.

[0041] Reference Figure 2 and Figure 3 A Bluetooth headset 4 is located on the side of the inner compartment 3 away from the inner compartment cover 5;

[0042] Reference Figure 3 The inner compartment cover 5 has a groove that matches the connecting block 102;

[0043] Reference Figure 3 , Figure 4 and Figure 5 An electromagnet matching the upper push block 105 is installed on the side of the lower push block 104 near the upper push block 105. An iron block is provided above the upper push block 105 to facilitate the attraction of the lower push block 104 and the upper push block 105 to close the earphone compartment 1.

[0044] Working principle: First, open the upper cover 101 and lower cover 103. Place the Bluetooth earphone 4 into the charging port of the inner compartment 3 for charging. Rotate the lower push block 104 and upper push block 105 with both hands. This will cause the upper cover 101 and lower cover 103 to rotate around the pivot 108, opening the earphone compartment 1. Then, by rotating the upper cover 101 and lower cover 103, the lower push block 104 and upper push block 105 will attract the earphones into the compartment. 1. To close the door, when you need to go out for exercise, you can press down the slide bar 602 on the push block 105. Pressing the slide bar 602 lightly will move it downwards, causing the fixing plate 603 and the retaining sleeve 607 to move downwards. Due to friction between the limiting sleeve 606 and the fixing seat 601, the limiting sleeve 606 will not move downwards. After the retaining sleeve 607 moves downwards and inserts into the push block 104, it squeezes the protrusion 611, causing multiple protrusions 611 to move outwards. Once the ferrule 607 has fully moved into the push block 104, the protrusion 611 moves inward until it locks the ferrule 607 in place, creating a secondary lock. Without touching the slide bar 602, the ferrule 607 remains locked inside the push block 104 and cannot be pulled out. When the earphone compartment 1 needs to be used, the slide bar 602 can be pressed down further by hand. At this time, the limiting sleeve 606 on the slide bar 602 moves downward under the constraint of the limiting ring 608, thus allowing the limiting sleeve 606 to fully move into the push block 104. In the protrusion 611, release the slide bar 602. At this time, the limiting sleeve 606 moves upward under the elastic force of the compression spring 604. The resistance of the protrusion 611 cannot follow the slide bar 602 to move upward until the locking sleeve 607 touches the limiting sleeve 606. At this time, the protrusion 611 cannot lock the locking sleeve 607. Then the limiting sleeve 606 and the locking sleeve 607 move upward with the slide bar 602 to complete the unlocking. To lock again, repeat the above operation to prevent the earphone compartment 1 from falling and causing the earphones to break.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
