[0028] The following is a further detailed description of the specific implementation of the present utility model in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] In the related art, when TWS earphones fall, it is easy for the Bluetooth earphones to fall out of the earphone compartment. The inventor found that a magnetic compartment cover is generally provided on the earphone compartment. When the earphone compartment cover is opened during the falling process, there is no other structure in the earphone compartment to fix the Bluetooth earphones. The Bluetooth earphones fall out of the earphone compartment, causing the Bluetooth earphones to be lost and damaged.
[0031] In view of this, if Figure 1 and Figure 2 As shown, some embodiments of the utility model provide a wireless headset 2, including a charging box 1 and the headset 2, and also including an elastic member 3, a limiting assembly and a first magnet 4; a accommodating cavity is provided in the charging box 1, the headset 2 extends into the accommodating cavity and is connected to the charging box 1; the first magnet 4 is provided on the headset 2, and the first magnet 4 and the limiting assembly are arranged to repel each other; the two ends of the elastic member 3 are respectively connected to the charging box 1 and the limiting assembly, and the elastic member 3 has a movement tendency to make the limiting assembly approach the headset 2, and the limiting assembly is snapped into the headset 2.
[0032] In the above embodiment, a accommodating cavity consistent with the shape of the earphone 2 is provided in the charging box 1, and an opening for placing the earphone 2 is provided at one end of the accommodating cavity. The charging box 1 is provided with a hinged flap at the opening of the accommodating cavity, and the flap can be connected to the charging box 1 by folding and magnetic attraction, so that the user can overcome the magnetic attraction and open the flap by folding to take out the earphone 2. Furthermore, in terms of the height, width and thickness of the charging box 1, the earphone 2 is arranged along the height direction of the charging box 1, and the elastic member 3 is arranged along the width direction of the charging box 1. The elastic member 3 can be a spring, and the two ends of the elastic member 3 are respectively connected to the charging box 1 and the limit assembly. The elastic member 3 has a movement tendency to make the limit assembly approach the earphone 2, and the limit assembly can be slidably connected to the charging box 1. The limit assembly can approach the earphone 2 and be inserted into the earphone 2 and connected to the earphone 2 under the push of the elastic member 3, so that the earphone 2 is clamped by the limit assembly during the falling process and cannot fall out of the accommodating cavity, thereby solving the technical problem that the earphone 2 is easily dropped out of the charging box 1 when the machine falls, resulting in the loss and damage of the earphone 2.
[0033] Optionally, the first magnet 4 is arranged on the earphone 2 and can be connected to the earphone 2 by gluing. The first magnet 4 and the limiting component are arranged to repel each other. When the earphone 2 enters the accommodating cavity with the first magnet 4, the first magnet 4 approaches the limiting component and makes the limiting component slide relative to the charging box 1 after reaching the effective distance, so that the limiting component pushes the elastic member 3 to start compressing, so that the limiting component moves away from the earphone 2, so that the earphone 2 can enter the accommodating cavity more conveniently. When the first magnet 4 starts to move away from the limiting component during the process of entering the accommodating cavity, the limiting component starts to move towards the earphone 2 under the action of the elastic member 3 until the limiting component is clamped on the earphone 2, thereby preventing the earphone 2 from falling out during the falling process. The earphone 2 is fixed in the charging box 1 by the limiting component so that the earphone 2 can be firmly connected to the limiting component during the falling process.
[0034] Some embodiments of the utility model provide a wireless headset 2, including an elastic member 3, a limiting assembly and a first magnet 4; the elastic member 3 always pushes the limiting assembly to move close to the headset 2, and catches the headset 2 through the limiting assembly to prevent the headset 2 from falling out of the accommodating cavity during the falling process, and after the first magnet 4 set on the headset 2 and the limiting assembly are set to repel each other, the headset 2 inserted into the accommodating cavity can compress the elastic member 3 by pushing the limiting assembly, so that the headset 2 can smoothly enter the accommodating cavity after the limiting assembly moves, meeting the requirement of placing the headset 2, and solving the technical problem that the headset 2 is easily dropped out of the charging box 1 when the machine falls, resulting in the loss and damage of the headset 2.
[0035] In some optional embodiments, a slide groove 9 is provided in the charging box 1; one end of the slide groove 9 is connected to the accommodating cavity, an elastic member 3 and a limit assembly are provided in the slide groove 9, and the limit assembly is slidably connected to the slide groove 9.
[0036] In the above embodiment, the cross-section of the slide groove 9 can be circular and arranged corresponding to the elastic member 3. The length direction of the slide groove 9 can be arranged parallel to the width direction of the charging box 1. One end of the slide groove 9 can be connected to the accommodating cavity, and a limit assembly is arranged at the end connected to the accommodating cavity, wherein the other end of the slide groove 9 can abut against the elastic member 3, and the elastic member 3 can be bonded to the end surface of the slide groove 9 by gluing. The elastic member 3 pushes the limit assembly to slide relative to the slide groove 9, so that the limit assembly can slide out of the limit assembly through one end of the slide groove 9 and extend into the accommodating cavity to engage with the earphone 2, thereby limiting the moving path of the elastic member 3 and the limit assembly through the slide groove 9, making the movement of the limit assembly more precise.
[0037] In some optional embodiments, the length direction of the slide slot 9 is arranged perpendicular to the moving path of the first magnet 4 .
[0038] In the above embodiment, when the earphone 2 enters the accommodating chamber with the first magnet 4, the earphone 2 will pass by the end face where the slide groove 9 is connected to the accommodating chamber with the first magnet 4, that is, the earphone 2 will first approach the end face where the slide groove 9 is connected to the accommodating chamber with the first magnet 4, and then move away from the end face where the slide groove 9 is connected to the accommodating chamber, so that the first magnet 4 can first push the limiting component to compress the elastic part 3, so that the earphone 2 can enter smoothly, and then when the first magnet 4 is away from the limiting component, the limiting component can be pushed out through the elastic part 3, so that the limiting component can clamp the earphone 2, so as to achieve the effect of being able to smoothly put in the earphone 2, and in the process of the charging box 1 falling, because the earphone 2 moves too fast, the earphone 2 is clamped in the process of the limiting component compressing the elastic part 3, so as to prevent the earphone 2 from falling out of the charging box 1.
[0039] In some optional embodiments, the limiting assembly includes a second magnet 5 and a sliding rod; the second magnet 5 is connected to the sliding rod, and the second magnet 5 and the first magnet 4 are arranged to repel each other; the sliding rod is respectively connected to the elastic member 3 and the second magnet 5.
[0040] In the above embodiment, the second magnet 5 can be set to a cylindrical shape, and the end surface of the second magnet 5 away from the earphone 2 can be connected to the elastic member 3, or can be connected to the sliding rod alone, and the sliding rod can be connected to the elastic member 3 and sleeved on the second magnet 5, the elastic member 3 can push the sliding rod, and then drive the second magnet 5 to move closer to the earphone 2 through the sliding rod, wherein the sliding rod can be inserted into the hole on one side of the earphone 2 to clamp the earphone 2, and the length of the sliding rod inserted into the earphone 2 can be X, X>0, thereby preventing the earphone 2 from falling.
[0041] Optionally, the first magnet 4 and the second magnet 5 are arranged to repel each other, wherein the action force F between the first magnet 4 and the second magnet 5 is greater than or equal to the elastic force of the elastic member 3 when the elastic member 3 is compressed by a length X, that is, after the action force F between the first magnet 4 and the second magnet 5 reaches a certain value, the elastic member 3 is compressed by at least a length X. At this time, the elastic member 3 just drives the sliding rod and the second magnet 5 to move at least a length X away from the earphone 2, so that the sliding rod can withdraw from the hole on the side of the earphone 2, thereby meeting the insertion requirement of the earphone 2.
[0042] Optionally, the force F between the first magnet 4 and the second magnet 5 may be 0.5N to 1N. For example, the force F may be 0.6N, 0.8N, 0.9N, etc.
[0043] In some optional embodiments, the slide rod includes a hanging portion 6 and a sliding portion 7; the sliding portion 7 is slidably connected to the slide groove 9, the second magnet 5 is connected to the hanging portion 6 through the sliding portion 7, and the hanging portion 6 extends into the accommodating cavity and is engaged with the earphone 2.
[0044] In the above embodiment, the sliding portion 7 can be cylindrical, and the end of the sliding portion 7 away from the elastic member 3 can be connected to the overhanging portion 6. The overhanging portion 6 can also be cylindrical. The diameter of the overhanging portion 6 is smaller than the diameter of the sliding portion 7. The axes of the sliding portion 7 and the overhanging portion 6 can be arranged to coincide with each other. The sliding portion 7 is slidably connected to the inner wall of the slide groove 9, so that the elastic member 3 can push the overhanging portion 6 to be close to or away from the earphone 2 through the sliding portion 7, so that the overhanging portion 6 can be engaged with the earphone 2, thereby fixing the earphone 2.
[0045] The second magnet 5 may be disposed on a side of the sliding portion 7 away from the overhanging portion 6 and bonded to the sliding portion 7 . The second magnet 5 may also be configured in a cylindrical shape.
[0046] In some optional embodiments, a mounting groove is provided on the end surface of the sliding portion 7 close to the elastic member 3, and the second magnet 5 is disposed in the mounting groove.
[0047] In the above embodiment, a mounting groove is provided at one end of the sliding portion 7 away from the overhanging portion 6, the mounting groove is cylindrical, and the mounting groove is recessed in the direction close to the overhanging portion 6. The size of the mounting groove can be consistent with the size of the second magnet 5. When the sliding portion 7 is connected to the second magnet 5, the second magnet 5 can be bonded to the mounting groove by glue, and the elastic member 3 can be connected to the end face of the sliding portion 7 away from the overhanging portion 6, so as to save space and make the second magnet 5 closer to the accommodating cavity, so that the force between the second magnet 5 and the first magnet 4 can be generated more easily.
[0048] In some optional embodiments, a limiting portion is provided at one end of the slide groove 9 close to the accommodating cavity, and the limiting portion abuts against the sliding portion 7 .
[0049] In the above embodiment, a limiting portion is provided on the end surface of the slide groove 9 communicating with the accommodating cavity. The limiting portion can be set as a circular ring. The limiting portion is set in the slide groove 9 and arranged flush with the surface of the accommodating cavity to make it easier for the earphone 2 to enter. Furthermore, the size of the hole on the limiting portion is larger than the size of the hanging portion 6 and smaller than the size of the sliding portion 7, so that when the elastic member 3 pushes the sliding portion 7 and the limiting portion close to the earphone 2, the sliding portion 7 is abutted by the limiting portion and cannot extend out of the slide groove 9, while the hanging portion 6 can extend through the hole on the limiting portion and be clamped on the earphone 2 to fix the earphone 2.
[0050] In some optional embodiments, a card slot 8 is provided on one side of the earphone 2 facing the slide slot 9 ; the card slot 8 extends along the direction in which the earphone 2 is inserted into the accommodating cavity, and one end of the overhanging portion 6 extends into the card slot 8 .
[0051] In the above embodiment, the card slot 8 can be in the shape of a long strip, and the length direction of the card slot 8 is arranged parallel to the direction in which the earphone 2 is inserted into the accommodating cavity. The card slot 8 runs through the surface of the earphone 2, and the width of the card slot 8 is greater than the diameter of the overhanging portion 6. The card slot 8 can be set as a blind hole, or it can be set as a through hole on the surface of the earphone 2 connected to the inside of the earphone 2. Preferably, the card slot 8 is set as a blind hole to prevent dust from entering the interior of the earphone 2, so that the overhanging portion 6 can penetrate into the card slot 8 by a length X.
[0052] In some optional embodiments, the extending direction of the locking slot 8 is perpendicular to the extending direction of the sliding slot 9 .
[0053] In the above embodiment, the extension direction of the card slot 8 can form an angle with the extension direction of the slide slot 9, so that the hanging portion 6 can be extended through the slide slot 9 and then inserted into the card slot 8 to engage with the earphone 2. Preferably, the extension direction of the card slot 8 is arranged perpendicular to the extension direction of the slide slot 9, so that the elastic deformation of the elastic member 3 can be smaller, that is, the moving path of the sliding portion 7 and the hanging portion 6 is smaller, which can reduce the insertion time and at the same time, the hanging portion 6 can be inserted into the earphone 2 more quickly to fix the earphone 2.
[0054] In some optional embodiments, one end of the slot 8 away from the first magnet 4 abuts against the overhanging portion 6 .
[0055] In the above embodiment, in the direction shown in the figure, the end of the slot 8 away from the first magnet 4, i.e., the upper end of the slot 8, is provided with a semicircular arc, and the diameter of the arc is consistent with the diameter of the overhanging portion 6, so that the connection between the slot 8 and the overhanging portion 6 is more stable, thereby preventing the earphone 2 from moving. At the same time, after the earphone 2 is inserted into the accommodating cavity, under the action of the first magnet 4 and the second magnet 5, the first magnet 4 and the second magnet 5 have a tendency to move away from each other. At this time, the second magnet 5 can push the first magnet 4 away, further fix the earphone 2, and allow the earphone 2 to have a tendency to move deeper into the accommodating cavity, thereby better fixing the earphone 2.
[0056] Optionally, during the falling process, for the earphone 2, according to the energy balance equation and the relationship between velocity and displacement, it can be deduced that:
[0057]
[0058] va*t=y;
[0059] Wherein, va is the movement speed of the first magnet 4, g is the acceleration of gravity, h is the drop height, y is the length of the card slot 8, and t is the time taken by the earphone 2 to move the distance y;
[0060] For the limiter assembly, a conservative calculation is made to exclude the deceleration factor and estimate the maximum distance xb that the limiter assembly can reach at time t. It can be deduced that:
[0061] m*vb=F*t;
[0062] vb*t=xb;
[0063] In the formula, m is the weight of the limit assembly, vb is the moving speed of the limit assembly, and xb is the moving distance of the slide bar;
[0064] In order to ensure that the earphone 2 does not fall out, that is, when the earphone 2 moves to the maximum stroke, the limit assembly is not completely separated from the earphone 2, the following conditions must be met:
[0065] xb <X;
[0066] Thus we can deduce:
[0067]
[0068] From this, it can be known that by controlling the length y of the slot 8, the weight m of the limit assembly, the length X of the overhang 6 inserted into the slot 8, and the force F between the first magnet 4 and the second magnet 5, the minimum drop height h of the charging box 1 can be determined. When the drop height is greater than h, the earphone 2 cannot fall out, but when the drop height is less than h, there is a chance of falling out. At the same time, when the drop height is less than h, the earphone 2 can be prevented from falling by the interaction force between the first magnet 4 and the second magnet 5 and the magnetic flip cover on the charging box.
[0069] Optionally, during the process of taking out the earphone 2, the earphone 2 can be taken out slowly, so that the force F between the first magnet 4 and the second magnet 5 on the earphone 2 compresses the spring to move the hanging part 6 a distance greater than X, so that the hanging part 6 extends out of the slot 8, thereby allowing the earphone 2 to be taken out smoothly.
[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
