Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and in particular to an earphone charging box and a TWS earphone. Background Art

[0002] With the development of China's electronic technology, more and more electronic devices have been widely used.

[0003] Earphones are a common small electronic device that can receive electrical signals from a media player or receiver and convert them into audible sound waves using a speaker close to the ear. With the popularity of portable electronic devices, earphones are mostly used in mobile phones, radios, portable video games, and digital audio players. There are many types of earphones, among which wireless earphones are popular because of their wireless transmission and easy portability.

[0004] TWS (True Wireless Stereo) headphones are a relatively advanced type of wireless headphones. The implementation of TWS technology is based on the development of chip technology. Smart electronic devices such as mobile phones can be connected to the main speaker, and then the main speaker can be connected to the slave speaker through Bluetooth wireless and other methods, realizing true Bluetooth left and right channel wireless separation. At present, with the continuous development of the TWS wireless Bluetooth headset market, the headset charging box for storage and charging has become an indispensable and important component. Its built-in wireless charging receiving module can be charged on a wireless charger, realizing the wireless functions of wireless Bluetooth and wireless charging.

[0005] In the prior art, the earphone body of a TWS earphone is generally placed in a charging box for charging. In order to solve the problem of possible motion interference between the earphone body and the charging box when the charging box is opened, the earphone body is usually installed at a deeper position at the bottom of the charging box. As a result, when the user takes it, he can only grab a small area above the top of the earphone body. In addition, the top of the earphone body is relatively smooth, and the friction between the user's fingers is very small, making it difficult for the user to smoothly take the earphone body out of the charging box.

[0006] Therefore, how to design an earphone charging box that allows users to easily take out the TWS earphones is a technical problem faced by those skilled in the art. Summary of the invention

[0007] The purpose of the present invention is to provide an earphone charging box and a TWS earphone, which are convenient for users to smoothly take out the TWS earphone from the charging box body.

[0008] In order to solve the above technical problems, the present invention provides an earphone charging box, comprising a box body for accommodating an earphone body, a box cover which can be opened and closed at the opening of the box body, a first in-position detector for detecting the opening and closing state of the box cover, a driving mechanism which is arranged in the box body and is used to drive the earphone body to perform vertical lifting movement, and a motion controller which is connected to the signal of the first in-position detector and is used to send a control instruction to the driving mechanism to drive the earphone body to vertically rise to above the opening of the box body when it detects that the box cover is in a preset open state.

[0009] Preferably, a mounting body for mounting the earphone body is detachably provided in the box body, and the output end of the driving mechanism extends into the mounting body and abuts against the bottom end of the earphone body.

[0010] Preferably, the mounting body is provided with two mounting holes which penetrate vertically and are used for mounting the earphone body, the bottom of the mounting body is provided with an inner cavity which is connected with each of the mounting holes, and the inner cavity is provided with a lifting plate which is connected with the output end of the driving mechanism and is used for driving each of the earphone bodies to rise and fall vertically in the mounting hole.

[0011] Preferably, abutment posts are erected at both sides above the lifting plate and are inserted into the corresponding mounting holes for abutting against the bottom end of the earphone body.

[0012] Preferably, the driving mechanism includes a driving motor buried in the bottom of the box body, a gear connected to the output shaft of the driving motor, a rack connected to the bottom of the lifting plate and meshing with the gear, and the movement direction of the rack is vertical.

[0013] Preferably, a second in-position detector for detecting the in-position state of the earphone body is embedded on the hole wall of the mounting hole, so that when its detection result suddenly changes from not in-position to in-position, the motion controller is triggered to send a control instruction to the driving mechanism to drive the lifting plate back to the initial position.

[0014] Preferably, at least two second in-position detectors are simultaneously arranged on the hole wall of the mounting hole along the vertical direction, and are located at least in the top and bottom areas of the mounting hole to avoid false triggering of the motion controller.

[0015] Preferably, the first in-position detector is specifically a pressure sensor or a displacement sensor, and the first in-position detector is embedded above the top of the side wall of the box body.

[0016] Preferably, one side edge of the box cover is flippably connected to the opening side wall of the box body.

[0017] The present invention also provides a TWS headset, comprising two earphone bodies housed in the earphone charging box described in any one of the above items for charging.

[0018] The earphone charging box provided by the present invention mainly includes a box body, a box cover, a first in-place detector, a driving mechanism and a motion controller. Among them, the box body is mainly used to contain the earphone body, the box cover can be opened and closed on the opening of the box body, and the first in-place detector is mainly used to detect the opening and closing state of the box cover. The driving mechanism is arranged in the box body, and is mainly used to drive the earphone body to perform vertical lifting movement in the box body. The motion controller is connected to the first in-place detector signal. When the first in-place detector detects that the box cover is in a preset open state, the motion controller is triggered to send a corresponding control instruction to the driving mechanism, so that the driving mechanism operates according to the received control instruction, and drives the earphone body to rise vertically in the box body, so that the earphone body is exposed above the opening of the box cover.

[0019] Therefore, in the earphone charging box provided by the present invention, when the user opens the box cover, the first in-position detector detects a corresponding signal, and controls the driving mechanism through the motion controller to drive the earphone body to rise vertically from the box body to above its opening, exposing most or all of the earphone body, so as to facilitate the user to grab and take the earphone body out of the box body. When the user puts the earphone body into the box body, the second in-position detector detects a corresponding signal, triggering the motion controller to send a control instruction to the driving mechanism, so that it drives the lifting plate to fall back to the initial position, so that the earphone can be charged or the charging box cover can be closed.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a specific implementation method provided by the present invention. Figure 2 It is a schematic diagram of the state where the earphone body a is pushed out of the box body 1.

[0030] In a specific implementation manner provided by the present invention, the earphone charging box mainly includes a box body 1, a box cover 2, a first in-place detector 3, a driving mechanism 4 and a motion controller 5.

[0031] The box body 1 is mainly used to contain the earphone body a, the box cover 2 is openably arranged on the opening of the box body 1, and the first in-position detector 3 is mainly used to detect the opening and closing state of the box cover 2. The driving mechanism 4 is arranged in the box body 1, and is mainly used to drive the earphone body a to perform vertical lifting movement in the box body 1.

[0032] The motion controller 5 is connected to the first in-place detector 3 by signal. When the first in-place detector 3 detects that the box cover 2 is in a preset open state, the motion controller 5 is triggered to send a corresponding control instruction to the driving mechanism 4, so that the driving mechanism 4 operates according to the received control instruction and drives the earphone body a to rise vertically in the box body 1, so that the earphone body a is exposed above the opening of the box cover 2.

[0033] Therefore, in the earphone charging box provided in this embodiment, when the user opens the box cover 2, the first in-position detector 3 detects the corresponding signal, and controls the driving mechanism 4 through the motion controller 5 to drive the earphone body a to rise vertically from the box body 1, and pushes part of the structure of the earphone body a to the top of the box body, thereby facilitating the user to take the earphone body a out of the box body 1.

[0034] In order to facilitate the switch of the box cover 2 on the box body 1, in this embodiment, one side of the box cover 2 is flipably connected to the opening side wall of the box body 1, so that the user can conveniently flip the box cover 2, and then open and close the opening of the box body 1 during the flipping movement of the box cover 2. Of course, the switch of the opening and closing state of the box cover 2 on the box body 1 is not limited to the flipping movement, and other methods such as the box cover 2 being vertically slidably arranged on the top of the box body 1 can also be adopted.

[0035] Generally, the opening and closing states of the box cover 2 are an open state and a closed state. However, considering that the box cover 2 is repeatedly opened and closed in a short period of time, in order to avoid misoperation, in this embodiment, the first in-position detector 3 can trigger the control instruction of the motion controller 5 under the dual conditions of detecting that the box cover 2 enters the open state and maintains it for a preset time (for example, more than 1s).

[0036] In a preferred embodiment of the first in-position detector 3, the first in-position detector 3 may be a pressure sensor, and is embedded in the top of the side wall of the box body 1. In this way, when the box cover 2 is in the closed state, the bottom surface of the box cover 2 is pressed against the top of the side wall of the box body 1, maintaining a certain degree of pressing force on the box body 1, and the pressure sensor can determine whether the box cover 2 is in the closed state by detecting the pressing force.

[0037] Of course, the first in-position detector 3 can also be a displacement sensor, etc., and is configured in this way. When the box cover 2 is in the box cover 2 state, the box cover 2 and the box body 1 remain relatively still, and the displacement of the box cover 2 remains zero. On the contrary, when the box cover 2 is in the opening and closing movement state, the displacement of the box cover 2 relative to the box body 1 will continue to change, and according to the increase or decrease of the displacement change value, it can be determined whether the box cover 2 is currently in the closing movement state or the opening movement state.

[0038] Considering the special shape of the earphone body a, in order to facilitate the installation of the earphone body a, this embodiment adds a mounting body 6 in the box body 1. At the same time, the output end of the driving mechanism 4 can extend into the mounting body 6 and abut against the bottom end of the earphone body a, so as to smoothly transmit power to the bottom end of the earphone body a, thereby driving the earphone body a to perform vertical lifting movement.

[0039] In addition, in order to improve the adaptability of the box body 1 to earphone bodies a of different types or sizes, in this embodiment, the mounting body 6 is detachably connected to the box body 1, for example, the two can be connected by a snap connection, etc. With this arrangement, when a different earphone body a needs to be installed, the corresponding mounting body 6 can be replaced in the box body 1.

[0040] In a preferred embodiment of the mounting body 6, the mounting body 6 may be in a rectangular block or cylindrical shape (same as the inner wall profile of the box body 1), and two mounting holes 601 are provided on the mounting body 6 and penetrate in the vertical direction, and an inner cavity 602 is provided at the bottom of the mounting body 6. Specifically, the two mounting holes 601 may be provided at two sides of the mounting body 6, and the two mounting holes 601 penetrate in the vertical direction, that is, the head and tail ends extend to the top and bottom of the mounting body 6, respectively. Considering that the earphone body a mainly includes a rod and a head, wherein the rod is installed in the mounting hole 601, as for the head, this embodiment also provides a mounting groove dedicated to installing the head above the top of the mounting body 6.

[0041] The inner cavity 602 is provided on the bottom surface of the mounting body 6, and specifically may be in the shape of a groove, the bottom of which is connected to the inner bottom surface of the box body 1 (or may not be connected to form a one-way sealing structure), and the top of which is simultaneously connected to the bottom end openings of the two mounting holes 601 on the mounting body 6. In addition, a lifting plate 401 is provided in the inner cavity 602, the bottom end of which is connected to the output end of the driving mechanism 4, and is mainly used to drive the earphone bodies a in the two mounting holes 601 to perform lifting and lowering movements in the vertical direction under the power drive of the driving mechanism 4.

[0042] Furthermore, in order to facilitate the lifting plate 401 to transmit the power of the driving mechanism 4 to the earphone body a, the present embodiment provides abutment columns 402 at both sides of the upper part of the lifting plate 401. Specifically, the abutment columns 402 extend vertically upward by a preset length above the lifting plate 401, and can be inserted into the corresponding mounting hole 601 to form an axial hole fit when the lifting plate 401 is at the lowest height position in the inner cavity 602 (abutting against the inner bottom surface of the box body 1). Since the rod portion of the earphone body a is installed in the mounting hole 601, the abutment column 402 can easily abut against the bottom end of the earphone body a, so that when the driving mechanism 4 drives the lifting plate 401 to perform vertical lifting movement, the abutment column 402 can smoothly abut against the bottom end of the earphone body a, lift it up and drive it to rise and fall synchronously. Of course, the length (height) of the abutment column 402 is specially designed, that is, when the lifting plate 401 drops to the lowest position, the earphone body a just drops into the mounting hole 601 to a position where its head is stably installed in the mounting groove, and keeps its bottom end abutting against the top of the abutment column 402.

[0043] like Figure 3 As shown, Figure 3 for Figure 1 The specific structural schematic diagram of the driving mechanism 4 is shown in FIG.

[0044] In a preferred embodiment of the driving mechanism 4, the driving mechanism 4 mainly includes a driving motor 403 and a transmission mechanism. Among them, the driving motor 403 is a power source, which is generally buried in the bottom of the box body 1. The transmission mechanism can also be buried in the bottom of the box body 1, but the end can extend out of the inner bottom surface of the box body 1 and be connected to the lifting plate 401. Specifically, the transmission mechanism in this embodiment mainly includes a gear 404 and a rack 405. Among them, the inner ring of the gear 404 is connected to the output shaft of the driving motor 403 through components such as a transmission key, and can rotate synchronously with the output shaft of the driving motor 403. Of course, the output shaft of the driving motor 403 can also be connected to a reduction mechanism first, and then the gear 404 is connected to the output end of the reduction mechanism. The rack 405 is arranged vertically in the box body 1, and a gear tooth is arranged on one side surface, which can be meshed with the gear 404 for transmission, and its top end extends out of the inner bottom surface of the box body 1 and is connected to the bottom surface of the lifting plate 401. With such arrangement, when the gear 404 rotates, the rotational power of the drive motor 403 can be converted into a vertical lifting movement of the rack 405 through meshing transmission with the rack 405, thereby driving the lifting plate 401 to perform synchronous lifting movement in the inner cavity 602.

[0045] In addition, considering that the earphone body a needs to be regularly put back into the box body 1 for charging after being taken out of the box body 1, in order to realize the purpose of automatically lowering the earphone body a in the box body 1 to reach the target position for charging, the second in-position detector 7 is embedded in the hole wall of the mounting hole 601 in this embodiment. The second in-position detector 7 is mainly used to detect the installation state of the earphone body a in the mounting hole 601, that is, whether it is in position. Generally, the second in-position detector 7 can be a photoelectric sensor, etc. Obviously, when the earphone body a remains installed in the mounting hole 601, the earphone body a is always in the in-position state, otherwise it is always in the non-in-position state.

[0046] The second in-place detector 7 is connected to the motion controller 5 by signal, and can continuously monitor the in-place status of the earphone body a in the mounting hole 601, and when its detection result suddenly changes from the "non-in-place state" of the earphone body a to the "in-place state", it indicates that the earphone body a is installed back into the box body 1 from the outside; at this time, the second in-place detector 7 triggers the motion controller 5 to send corresponding control instructions to the drive mechanism 4, so that the drive mechanism 4 drives the lifting plate 401 to perform a vertical descending movement, and the lifting plate 401 falls back to the initial position, so that the earphone body a descends to the charging position in the mounting hole 601, and at the same time, it is convenient for the box cover 2 of the earphone charging box to be closed.

[0047] Of course, if the detection result of the second in-place detector 7 suddenly changes from the "in-place state" of the earphone body a to the "out-of-place state", it means that the earphone body a is removed from the mounting hole 601 by the user. At this time, the driving mechanism 4 may be in a standby state.

[0048] In addition, considering that when the user actually uses the earphone body a, there may be a situation where the earphone body a is quickly plugged and unplugged in the box body 1 in a short time. In this case, the lifting plate 401 does not need to immediately fall back to the initial position to charge the earphone body a. Instead, the lifting plate 401 needs to remain in the current state for a period of time. In order to cope with this situation and avoid false triggering, at least two second in-place detectors 7 are provided on the hole wall of the mounting hole 601 in this embodiment. Take the example of two second in-place detectors 7 provided on the hole wall of the mounting hole 601, and the two second in-place detectors 7 are respectively located at the top and bottom areas of the mounting hole 601 and distributed vertically. When the earphone body a is put into the box body 1 from the outside, it can only be judged that charging is required when the earphone body a triggers the second in-place detector 7 on the top and the second in-place detector 7 on the bottom successively; otherwise, if only the second in-place detector 7 on the top is triggered and the second in-place detector 7 on the bottom is not triggered, it is judged that charging is not required at this time, and the lifting plate 401 maintains the current state.

[0049] On the contrary, when the triggering order of the two second in-place detectors 7 is reversed, that is, the lower second in-place detector 7 is triggered first and then the upper second in-place detector 7 is triggered, it means that the user has completely taken the earphone body a out of the box body 1, and the driving mechanism 4 can be in a standby state.

[0050] This embodiment also provides a TWS headset, which mainly includes an earphone body a and an earphone charging box for holding the earphone body a and charging it, wherein the specific content of the earphone charging box is the same as the above-mentioned related content and will not be repeated here.

[0051] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
