Description

Technical Field

[0001] This utility model relates to the field of shared equipment technology, and in particular to a rechargeable base. Background Technology

[0002] In recent years, with the booming development of the global tourism industry, tourists' demands for travel experiences have been increasing. They are no longer satisfied with simple sightseeing but are more inclined to in-depth cultural exploration. Against this backdrop, traditional tour guide methods have gradually revealed many shortcomings. Specifically, traditional tour guides may disturb other tourists by speaking too loudly, thus affecting the overall order of the scenic area.

[0003] To address this issue, audio guide headphones were developed. These headphones create a quiet environment for visitors, allowing them to focus more intently on the narration without external distractions. Furthermore, their use helps protect cultural relics at attractions, preventing potential damage from noise. Visitors can rent audio guide headphones at visitor centers or ticket offices to enjoy personalized, in-depth guided tours, significantly enhancing their travel experience.

[0004] However, existing audio guide headsets have several shortcomings in terms of charging. Since these headsets require periodic charging, and most currently available are wired, staff in scenic areas with a large number of headsets need to manually connect each one to a charger. This is not only cumbersome but also involves a complex charging process. Furthermore, when the number of charging sockets is limited, it's necessary to wait for the current batch of headsets to finish charging before charging the next batch, significantly reducing charging efficiency.

[0005] Furthermore, wired charging results in numerous, messy charging cables that are difficult to manage. These tangled cables not only affect the cleanliness of the scenic area but also pose a significant safety hazard, potentially causing fires due to short circuits or other issues. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a rechargeable base in which at least one set of earphones is inserted, so that electrical energy is input from the charging base into the earphones;

[0007] The charging dock includes:

[0008] The enclosure contains the battery module and the control module.

[0009] A charging compartment is disposed inside a box, and the charging compartment is provided in at least one group, with the at least one group of charging compartments being equidistantly distributed along the length of the box.

[0010] The charging contact pin is fixed inside the charging case. When the earphone is fully inserted into the charging case, the charging contact pin is inserted into the charging port at one end of the earphone.

[0011] This invention allows multiple earphones to be inserted into the charging case. At this time, the charging contacts align with the charging buckle to achieve a fast charging connection for the earphones. Simultaneously, this invention enables multiple earphones to be charged at the same time, providing convenient plug-and-charge functionality, improving charging efficiency, and avoiding the drawbacks of numerous, messy, and difficult-to-manage charging cables that could cause fires. The battery module provides power for charging the earphones, allowing them to continue charging even during power outages.

[0012] Furthermore, the charging compartment includes a compartment body, an insertion port of which is located on the outside of the compartment body, a compartment door is provided at the insertion port, one side of the compartment door is pivotally connected to the compartment body, and a third elastic element is installed on the pivot axis between the compartment door and the compartment body.

[0013] When the earphones are removed from the charging case, the door rotates under the restoring action of the third elastic element, thereby sealing the insertion port of the charging case and preventing dust or humid air from entering the charging case when it is empty.

[0014] Furthermore, the charging dock also includes:

[0015] The ejector base is integrally set inside the charging case and is elastically slidably connected to the charging case. The ejector base has a slot that defines a space for accommodating the end of the earphone with a charging port. A charging slot is provided on the ejector base at the position corresponding to the charging port. When the earphone is inserted into the charging case, the charging pin passes through the charging slot and is inserted into the charging port.

[0016] A locking structure is located on one side of the charging case. When the earphones are fully inserted into the charging case, the locking structure secures the earphones inside the case.

[0017] Furthermore, a first gear is provided on one side of the ejection base, and the first gear is rotatably mounted on the side of the ejection base. A second elastic element is provided on the connecting shaft between the first gear and the ejection base.

[0018] One side of the housing is provided with a limiting groove for the first gear to pass through, and a first rack that meshes with the first gear is provided outside the limiting groove.

[0019] Furthermore, the ejection base has outwardly protruding Z-shaped blocks on its side;

[0020] A first limiting groove is provided on one side of the chamber corresponding to the Z-shaped block, allowing the Z-shaped block to pass through. When the ejection base moves, the Z-shaped block moves linearly along the first limiting groove.

[0021] Furthermore, the locking structure includes:

[0022] A U-shaped plate with a locking block on its inner side, which matches a locking groove on one side of the earphone.

[0023] The lifting assembly drives the U-shaped plate to move linearly, so that the locking block is inserted into or removed from the locking groove.

[0024] The U-shaped plate is wrapped around the outside of the chamber and connected to the chamber through the first elastic element. A movable slot is opened on one side of the chamber corresponding to the position of the locking block. The locking block extends from the outside of the chamber through the movable slot into the inside of the chamber.

[0025] Furthermore, a first positioning groove for accommodating a portion of the U-shaped plate is provided at the location where the movable slot is provided in the hopper body, and a positioning block is provided at one end of the first positioning groove;

[0026] The U-shaped plate has a second limiting groove at one end, and the positioning block is accommodated in the second limiting groove. When the lifting component drives the U-shaped plate to move linearly, the second limiting groove moves linearly relative to the positioning block.

[0027] Furthermore, one end of the U-shaped plate is a slope;

[0028] The lifting assembly includes:

[0029] The motor is fixedly installed on the outside of the compartment.

[0030] The second gear is mounted on the motor and is driven to rotate by the motor.

[0031] The frame contains the aforementioned second gear. Inside the frame, there is a second rack that meshes with the second gear. A lifting rod is provided on one side of the frame, which is positioned to correspond to the inclined surface and maintains contact with the inclined surface.

[0032] When the earphones are inserted into the charging case, the end of the earphone inserted into the case acts on the ejector base, causing it to move linearly. During the linear movement of the ejector base, the first gear installed on one side of the ejector base also moves linearly. Since the first gear meshes with the first rack fixed on the outside of the case, it causes the first gear to rotate. The rotation of the first gear twists the second elastic element, causing the second elastic element to store energy. When the earphones are fully inserted into the case, the motor drives the lifting rod to move linearly away from the inclined plane. The U-shaped plate moves linearly inward under the action of the third elastic element. At this time, the locking block is inserted into the locking groove, completing the locking of the earphones and preventing them from loosening during charging. When the earphones are needed, the motor drives the frame to move linearly, causing the lifting rod to contact the inclined plane, which in turn drives the U-shaped plate to move outward. At this time, the locking block leaves the locking groove, the first elastic element returns, and drives the first gear to rotate. Since the first gear meshes with the first rack, it causes the first gear to move linearly along the first rack, causing the ejector base to move linearly and eject the earphones for easy removal.

[0033] Furthermore, the charging dock also includes:

[0034] The first sensing device is located on the side of the compartment where the charging contact pin is located;

[0035] A second sensing device is installed in the insertion port;

[0036] The third sensing device is located on the outside of the hopper, corresponding to the lifting rod.

[0037] This utility model has the following advantages:

[0038] This invention allows multiple earphones to be inserted into the charging case. At this time, the charging contacts align with the charging buckle to achieve a fast charging connection for the earphones. Simultaneously, this invention enables multiple earphones to be charged at the same time, providing convenient plug-and-charge functionality, improving charging efficiency, and avoiding the drawbacks of numerous, messy, and difficult-to-manage charging cables that could cause fires. The battery module provides power for charging the earphones, allowing them to continue charging even during power outages. Attached Figure Description

[0074] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0075] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0076] As described in the background section, audio guide headphones require periodic charging, and most audio guide headphones on the market are still wired. Within scenic areas, due to the large number of audio guide headphones, staff need to manually connect each headphone to a charger one by one. This is not only cumbersome but also involves a relatively complicated charging process. When the number of charging sockets is limited, it is necessary to wait for the current batch of headphones to finish charging before charging the next batch, which significantly reduces charging efficiency.

[0077] Example 1:

[0078] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a rechargeable dock, such as... Figure 1 As shown, at least one set of earphones 2000 is inserted into the charging base 1000 so that electrical energy is input from the charging base into the earphones;

[0079] like Figure 2 , 7 As shown, the charging dock 1000 includes:

[0080] The housing 1100 contains a battery module and a control module.

[0081] A charging compartment 1200 is disposed inside a housing 1100. The charging compartment is provided in at least one set, and the at least one set of charging compartments is equidistantly distributed along the length of the housing.

[0082] The charging contact 1240 is fixed inside the charging case. When the earphone is fully inserted into the charging case, the charging contact is inserted into the charging port 2100 at one end of the earphone.

[0083] In this embodiment, a certain number of charging compartments can be set inside the housing as needed. By inserting the earphones into the charging compartments, when the earphones are fully inserted, the charging pins are inserted into the charging port. At this time, the control module controls the power input to the earphones to realize the charging of the earphones.

[0084] In this embodiment, by inserting the earphones into the charging case, the charging contacts align with the charging buckle, enabling fast charging of the earphones. This invention also allows for simultaneous charging of multiple earphones, providing convenient plug-and-charge functionality, improving charging efficiency, and avoiding the drawbacks of numerous, messy, and difficult-to-manage charging cables that could cause fires. The battery module provides power to the earphones, ensuring continued charging even during power outages.

[0085] In this embodiment, as Figure 3 As shown, the charging compartment includes a compartment body 1220, with an insertion port on the outside of the housing 1100. A compartment door 1210 is provided at the insertion port, and one side of the compartment door is pivotally connected to the compartment body. A third elastic element 1900 is installed on the pivot axis between the compartment door and the compartment body.

[0086] When the earphones are removed from the charging case, the door rotates under the restoring action of the third elastic element, thereby sealing the insertion port of the charging case and preventing dust or humid air from entering the charging case when it is empty.

[0087] Example 2:

[0088] When the earbuds are inserted into the charging case, they may wobble under external force, which may cause poor contact between the charging port and the pins. Also, when the earbuds are fully inserted, only a small portion may be exposed, making them difficult to remove.

[0089] Therefore, in order to solve this technical problem, this embodiment of technical embodiment 1 proposes an improvement, such as... Figure 3 , 6 As shown, the charging dock also includes:

[0090] The ejection base 1230 is integrally disposed in the charging case and is elastically slidably connected to the charging case. The ejection base 1230 has a slot 1233 that defines the end of the earphone with a charging port. A charging slot is provided on the ejection base at the position corresponding to the charging port. When the earphone is inserted into the charging case, the charging pin passes through the charging slot and is inserted into the charging port.

[0091] The locking structure 1500 is located on one side of the charging case. When the earphones are fully inserted into the charging case, the locking structure secures the earphones inside the case.

[0092] like Figure 10 As shown, a first gear 1231 is provided on one side of the ejection base. The first gear is rotatably mounted on the side of the ejection base, and a second elastic element is provided on the connecting shaft between the first gear and the ejection base.

[0093] like Figure 8 As shown, a limiting groove 1221 for the first gear to pass through is provided on one side of the housing, and a first rack 1222 that meshes with the first gear is provided outside the limiting groove.

[0094] When the earphones are inserted into the charging case, one end of the earphone acts on the ejector base, causing it to move linearly under the action of external force. During the linear movement of the ejector base, the first gear installed on one side of the ejector base also moves linearly. Since the first gear meshes with the first rack fixed on the outside of the charging case, the first gear will rotate. The rotation of the first gear will twist the second elastic element, causing the second elastic element to store energy. When the earphones are fully inserted into the charging case, the locking structure locks the earphones to keep them relatively fixed to the charging case, preventing them from loosening during charging. The locking structure releases the earphones, the first elastic element returns to its original position, and drives the first gear to rotate. Since the first gear meshes with the first rack, the first gear will move linearly along the first rack, causing the ejector base to move linearly and eject the earphones for easy removal.

[0095] In this embodiment, if Figure 10 As shown, the ejection base 1230 has an outwardly protruding Z-shaped block 1232 on its side;

[0096] like Figure 9 As shown, a first limiting groove 1224 is provided on one side of the chamber corresponding to the Z-shaped block for the Z-shaped block to pass through. When the ejection base moves, the Z-shaped block moves linearly along the first limiting groove.

[0097] When the launch base moves, the Z-shaped block moves linearly along the first limiting groove. When the Z-shaped block moves to the end of the first limiting groove, the side of the Z-shaped block and the end face of the first limiting groove form an interface or stop, thereby preventing the Z-shaped block from continuing to move and thus limiting the linear movement of the launch base.

[0098] In this embodiment, as Figure 5 As shown, the locking structure includes:

[0099] U-shaped plate 1510, such as Figure 11 As shown, a locking block 1513 is provided on the inner side of the U-shaped plate 1510, which matches the locking groove 2200 on the side of the earphone.

[0100] The lifting assembly 1520 drives the U-shaped plate to move linearly, so that the locking block is inserted into or removed from the locking groove.

[0101] like Figure 5 As shown, the U-shaped plate wraps around the outside of the compartment and is connected to the compartment via the first elastic element 1400, as... Figure 9 As shown, a movable slot 1223 is provided on one side of the compartment corresponding to the position of the locking block, and the locking block extends from the outside of the compartment through the movable slot into the compartment.

[0102] The lifting assembly releases the U-shaped plate, which moves linearly inward under the action of the third elastic element. At this time, the locking block is inserted into the locking groove to lock the headphones, preventing them from loosening during charging. When the headphones need to be used, the lifting assembly abuts against the U-shaped plate, thereby driving the U-shaped plate to move outward. At this time, the locking block leaves the locking groove, releasing the headphones.

[0103] In this embodiment, as Figure 8 As shown, a first positioning groove 1226 for accommodating part of the U-shaped plate is provided at the location where the movable slot is provided in the hopper body, and a positioning block 1227 is provided at one end of the first positioning groove.

[0104] like Figure 11 As shown, a second limiting groove 1512 is provided at one end of the U-shaped plate, and the positioning block is accommodated in the second limiting groove. When the lifting component drives the U-shaped plate to move linearly, the second limiting groove moves linearly relative to the positioning block.

[0105] When the U-shaped plate moves, the second limiting groove moves linearly relative to the positioning block. When the end of the second limiting groove contacts the side of the positioning block, the side of the positioning block and the end face of the second limiting groove form an interface or stop, thereby preventing the U-shaped plate from continuing to move and thus limiting the linear movement of the U-shaped plate.

[0106] In this embodiment, as Figure 11 As shown, one end of the U-shaped plate is an inclined surface 1511;

[0107] The lifting assembly includes:

[0108] Motor 1511, which is fixedly installed on the outside of the compartment body;

[0109] The second gear 1524 is mounted on the motor and is driven to rotate by the motor.

[0110] The frame 1521 houses the aforementioned second gear. Inside the frame, there is a second rack 1525 that meshes with the second gear. A lifting rod 1523 is provided on one side of the frame, which is positioned to correspond to the inclined surface and maintains contact with it.

[0111] When the earphones are fully inserted into the housing, the motor drives the lifting rod to move linearly away from the inclined plane. The U-shaped plate moves linearly inward under the action of the third elastic element. When the earphones are needed, the motor drives the frame to move linearly, causing the lifting rod to contact the inclined plane, which in turn drives the U-shaped plate to move outward. At this time, the locking block leaves the locking groove, the first elastic element returns, and drives the first gear to rotate. Since the first gear meshes with the first rack, the first gear will move linearly along the first rack, which will drive the ejection base to move linearly, ejecting the earphones for easy removal.

[0112] In addition, such as Figure 7 As shown, a guide seat 1225 can also be installed on the outside of the compartment corresponding to the frame 1521. The guide seat guides the linear movement of the frame and also restricts the position of the frame, thereby improving the movement accuracy of the frame.

[0113] This embodiment can also be used in conjunction with shared software. For example, by setting a QR code 1110 in a preset area on the box, users can enter the mini-program by scanning the QR code. After operating in the mini-program, a signal is sent to the control module, which then controls the motor to release the earphones and make them pop out for the user to use. At the same time, billing begins. When returning the earphones, after inserting them into the charging case, the control module will control the motor to lock the earphones and send a signal to the user to stop billing and settle the fee.

[0114] In addition, such as Figure 4 , 5 The charging dock shown in Figure 7 may further include:

[0115] The first sensing device 1250 is located on the side of the compartment body where the charging contact pin is located;

[0116] The second sensing device 1300 is located at the insertion port;

[0117] The third sensing device 1600 is located on the outside of the hopper body, corresponding to the lifting rod.

[0118] When the earphone is inserted, the ejector base moves linearly inward. When the ejector base touches the first sensing device or the first sensing device detects that the ejector base has moved to a preset position, the control module controls the motor to work so that the locking block is inserted into the locking slot. At the same time, the battery module is controlled to input power into the earphone.

[0119] When the earphone pops out, the second sensor can detect whether the earphone has been removed, so that the control module can accurately determine whether the earphone is unlocked and not in use. This allows the control module to remind the user through voice, light indicators, SMS messages, or other means.

[0120] The third sensing device can detect the movement stroke of the lifting rod, thereby controlling the motor to stop working in a timely manner.

[0121] In this embodiment, the first, second, and third sensing devices can be selected from commonly used electronic components such as sensors and limiters in the prior art.

[0122] Example 3:

[0123] To facilitate the stacking of the bases, the bases in this embodiment can be placed with the insertion port facing one side. However, simply stacking them will cause the bases to wobble and tip over easily.

[0124] Therefore, in order to solve this technical problem, this embodiment proposes an improvement, such as... Figure 13 As shown, the charging dock also includes:

[0125] The first latch 1700 is located on one side of the compartment body;

[0126] The second latch 1800 is configured to correspond to the first latch.

[0127] The first and second latches work together to secure the two overlapping charging bases.

[0128] like Figure 14 As shown, the first latch includes:

[0129] A first mounting box 1710 has a receiving groove inside the first mounting box 1710;

[0130] The locking tongue 1720 is housed in a receiving groove, and a slot 1721 is provided at the end of the locking tongue;

[0131] A rotating part is provided on the side of the first mounting box. By rotating the rotating part, the locking tongue is driven to move linearly so that the locking tongue can enter and exit the receiving groove.

[0132] like Figure 14 As shown, the second latch includes:

[0133] The second mounting box 1810 is provided with a locking tongue groove 1811, which is connected to the locking tongue.

[0134] Tongue click 1840, such as Figure 15 As shown, the spring 1840 is rotatably disposed in the second mounting box. The spring has a locking block, which is disposed around the rotation axis of the spring and the second mounting box. The locking block is disposed in the locking tongue groove.

[0135] A lever 1820, one end of which is connected to the rotating shaft of the spring, and the lever is connected to the second mounting box via a fourth elastic element 1830;

[0136] like Figure 21 As shown, when the latch is fully inserted into the latch groove, the locking block is locked in the groove.

[0137] like Figure 20 As shown, the first and second latches work together to keep the charging bases relatively fixed when they are stacked. They can also position the charging bases to prevent them from shifting and causing them to shake or tip over.

[0138] In this embodiment, as Figure 16 , 18 As shown, the first latch may further include:

[0139] Transmission unit 1730, the aforementioned rotating part is mounted on the transmission unit;

[0140] The third gear 1740 is coaxially mounted with the rotating part. The third gear is located inside the first mounting box and partially penetrates into the receiving groove.

[0141] A third rack 1722 that meshes with the third gear is provided on the surface of the locking tongue 1720.

[0142] like Figure 17 As shown, the transmission unit includes:

[0143] Transmission box 1733, the transmission box is fixedly installed on the side of the first mounting box;

[0144] Worm gear 1731, the worm gear is installed in the transmission box and is coaxially mounted with the third gear;

[0145] The worm 1732 is integrally housed within the transmission box and meshes with the worm wheel. One end of the worm passes through the transmission box and connects to the rotating part.

[0146] In this embodiment, both the end of the locking tongue and the side of the slot near the end are provided with arc surfaces.

[0147] When overlapping is required, rotate the rotating part to make the bolt move linearly, causing it to extend out of the first mounting box, and insert the bolt into the corresponding bolt slot, such as... Figure 21 As shown, as the latch is inserted, it contacts the flat side of the spring, causing the spring to rotate and disengage from the latch groove. During the rotation of the spring, the lever also rotates, compressing or stretching the fourth elastic element. When the latch is fully inserted, the slot position corresponds to the locking block. The locking block is no longer restricted by external force and rotates under the action of the fourth elastic element, thus locking itself in the slot. To disassemble, simply rotate the lever to rotate the locking block away from the slot to separate the charging base.

[0148] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those 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 is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
