Description

Technical Field

[0001] The present application relates to the technical field related to Bluetooth headsets, and in particular to a wireless Bluetooth headset charging box. Background Art

[0002] With the continuous development of wireless communication technology, wireless Bluetooth headsets have rapidly become popular in the consumer market due to their convenience and excellent user experience. As a supporting device, the rational design of wireless Bluetooth headset charging boxes is crucial to the user experience.

[0003] Currently, most wireless Bluetooth earphone charging cases on the market use a traditional design. After opening the lid, the earphones attach to the bottom of the charging case, requiring consumers to pinch the top of the earphones with their fingers to remove them. Furthermore, very little of the earphones is exposed after opening the lid, making removal extremely inconvenient. This design not only causes problems for consumers and reduces the user experience, but also makes it difficult for users to remove the earphones in certain scenarios, such as one-handed operation or in dimly lit environments. Furthermore, frequently pinching the top of the earphones to remove and place them can cause a certain degree of wear and tear on the earphones, affecting their lifespan and performance.

[0004] These have restricted the further development of wireless Bluetooth headset charging boxes in the market. A new design is urgently needed to solve the problems of difficulty in removing the headset and easy damage during placement and removal, so as to improve the user experience and meet the market demand for high-quality and convenient products.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0034] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside", "outside", "inside", "outside", "below", "beneath", "above", "above", "front", "back", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a position flip or a change in posture or a change in motion state, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device can be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptions used herein have been interpreted accordingly.

[0035] Free from the constraints of traditional cables, wireless Bluetooth earphones are compact, conform to the contours of the ear, and are easy to carry. Leveraging Bluetooth technology, they can quickly pair with devices like phones and computers, enabling stable audio transmission and an immersive music and call experience, greatly enhancing convenience.

[0036] Wireless Bluetooth earbuds often come with a charging case, which serves not only as a storage container but also as a way to recharge the earbuds, extending their usage time. When the charging case is fully charged, the earbuds can be placed inside for immediate charging, ensuring extended battery life.

[0037] However, some existing charging case designs have certain flaws. When opened, the earphones attach to the bottom of the case, leaving only a small portion exposed. To remove the earphones, users must pinch the top of the earphones with their fingers, which creates a narrow space and makes exerting force difficult, making removal difficult and reducing ease of use.

[0038] To alleviate the above problems, refer to Figure 1-Figure 5 The present invention provides a wireless Bluetooth headset charging case. When the lid is opened, the upper case body 1 can move relative to the lower case body 2. During the relative movement of the upper and lower cases 2, the earphones 3 can follow the upper case body 1, maintaining an adsorption force between the earphones 3 and the upper case body 1. In this way, the tail 32 of the earphones can be exposed from the lower case body 2, and the user can directly hold the tail 32 of the earphones for convenient access. This can alleviate the technical problems of difficulty in removing the earphones 3 from the wireless Bluetooth headset charging case and the risk of damage during handling.

[0039] For the sake of convenience of description, the directions of the embodiments of the present application are based on the state in which the upper box body 1 in the charging box is located above the lower box body 2. The longitudinal direction is defined as the direction from the upper box body 1 to the lower box body 2, that is, the longitudinal direction is the height direction of the upper box body or the lower box body, and the transverse direction is defined as the width direction or length direction of the upper box body 1 or the lower box body 2. The following scheme is explained by taking the transverse direction as the length direction of the lower box body 2 as an example.

[0040] The wireless Bluetooth headset charging box provided in an embodiment of the present application includes: an upper box body 1 and a lower box body 2, wherein the upper box body 1 includes an upper cover electromagnetic assembly 12, and the upper cover electromagnetic assembly 12 is configured to automatically turn on when the cover is open, so that the upper cover electromagnetic assembly 12 forms a first adsorption force on the earphone 3, and the upper cover electromagnetic assembly 12 is configured to automatically cut off the power when the cover is closed, so that the upper cover electromagnetic assembly 12 loses adsorption on the earphone 3; the lower box body 2 includes a lower cover electromagnetic assembly 22, and the lower cover electromagnetic assembly 22 is configured to automatically turn on when the cover is closed, so that the lower cover electromagnetic assembly 22 forms a second adsorption force on the earphone 3, and the second adsorption force is opposite to the direction of the first adsorption force; the lower cover electromagnetic assembly 22 is configured to automatically cut off the power when the cover is open, so that the lower cover electromagnetic assembly 22 loses adsorption on the earphone 3.

[0041] Exemplarily, both the upper cover electromagnetic assembly 12 and the lower cover electromagnetic assembly 22 can be understood as having a structure with an electromagnetic coil and an iron core. Depending on actual application requirements, the electromagnetic coil can be electrically connected to a power source directly or indirectly via a wire, so that the magnetic force generated by the upper cover electromagnetic assembly 12 and the lower cover electromagnetic assembly 22 when powered on acts on the earphone 3. The timing at which the upper cover electromagnetic assembly 12 and the lower cover electromagnetic assembly 22 act on the earphone 3 is different in the embodiment of the present application. When the cover is open, the upper cover electromagnetic assembly 12 can generate a magnetic force when powered on, thereby generating a first upward attraction force on the earphone 3; when the cover is closed, the lower cover electromagnetic assembly 22 can generate a magnetic force when powered on, thereby generating a second downward attraction force on the earphone 3. The upward and downward directions here are both in the longitudinal direction.

[0042] A wireless Bluetooth headset charging box according to an embodiment of the present application is used, by setting an upper cover electromagnetic component 12 on the upper box body 1 and a lower cover electromagnetic component 22 on the lower box body 2, and configuring the upper cover electromagnetic component 12 to automatically turn on and form a first adsorption force on the earphone head 31 when the cover is opened, and configuring the lower cover electromagnetic component 22 to automatically turn off and lose adsorption on the earphone tail 32 when the cover is opened. In this way, in the open state, the overall structure of the earphone 3 can only withstand the first adsorption force of the upper cover electromagnetic component 12. In this way, the overall structure of the earphone 3 can move with the upper box body 1, and can make the earphone tail 32 extend from the lower box body 2, or can make the earphone tail 32 fall out of the lower box body 2, and at least part of the structure of the earphone tail 32 can be convenient for the user to hold. Furthermore, the upper cover electromagnetic assembly 12 is configured to automatically cut off the power and lose the adsorption on the earphone head 31 when the cover is closed, and the lower cover electromagnetic assembly 22 is configured to automatically turn on and form a second adsorption force on the earphone tail 32 when the cover is closed. In this way, in the closed state, the overall structure of the earphone 3 can be stably limited to the lower box body 2 under the action of the second adsorption force, which can help the Bluetooth earphone 3 to be stably in the charging state.

[0043] Exemplarily, the upper box body 1 includes a first accommodating cavity 11, which is used to accommodate the earphone head 31; the upper cover electromagnetic component 12 is configured to automatically turn on and form a first adsorption force on the earphone head 31 when the cover is open, and the upper cover electromagnetic component 12 is configured to automatically turn off and lose the first adsorption force on the earphone head 31 when the cover is closed.

[0044] Exemplarily, the upper cover electromagnetic assembly 12 and the lower cover electromagnetic assembly 22 can be understood as electromagnetic structures that can generate magnetic attraction when energized, or can be understood as a combination structure including electromagnetic structures, depending on the actual application scenario.

[0045] The present application does not limit the preset value ranges of the first adsorption force and the second adsorption force, as long as the earphone head 31 can be stably adsorbed to the upper box body 1 through the first adsorption force, and the earphone tail 32 can be stably adsorbed to the lower box body 2 through the second adsorption force.

[0046] Illustratively, the upper box body 1 and the lower box body 2 can be respectively constructed as an integrally formed box body structure, or the upper box body 1 and the lower box body 2 can be respectively constructed as a detachable structure.

[0047] When the upper box body 1 is constructed as a detachable structure, the upper box body 1 may include a top cover and an upper cavity. The upper cavity may be constructed as a structure with an opening from top to bottom. For example, the top cover may cover the top opening of the upper cavity.

[0048] The embodiment of the present application does not limit the detachable connection method between the top cover and the upper cavity. For example, the top cover and the upper cavity can be connected by magnetic attraction, mortise and tenon connection, adhesive connection, or snap connection.

[0049] Considering that the upper box body 1 and the lower box body 2 are slidably assembled to realize the power on and off of the upper cover electromagnetic assembly 12 or the lower cover electromagnetic assembly 22, in the wireless Bluetooth headset charging box provided in the embodiment of the present application, the upper box body 1 and the lower box body 2 are slidably assembled; the upper box body 1 includes a conductive metal sheet 131 and a metal block 14 spaced apart from the conductive metal sheet 131 in a direction from the upper box body 1 to the lower box body 2; it should be noted that the metal block 14 is located below the conductive metal sheet 131;

[0050] Illustratively, a sliding assembly is adopted between the upper box body 1 and the lower box body 2, so that the upper box body 1 can slide relatively away from the lower box body 2, and then under the action of the first adsorption force, the overall structure of the earphone 3 follows the upper box body 1 to move in the direction away from the lower box body 2, so as to free up space for the user to hold the tail 32 of the earphone.

[0051] When the cover is open, the circuit formed between the upper cover electromagnetic assembly 12, the conductive metal sheet 131 and the power supply remains electrically connected, and the circuit formed between the metal block 14 and the lower cover electromagnetic assembly 22 and the power supply is in a disconnected state; when the cover is closed, the circuit formed between the conductive metal sheet 131 and the upper cover electromagnetic assembly 12 and the power supply is in a disconnected state; the circuit formed between the metal block 14 and the lower cover electromagnetic assembly 22 and the power supply remains electrically connected.

[0052] Specifically, the upper case 1 includes an upper cover electromagnetic assembly 12, a conductive metal sheet 131, and a metal block 14, and the lower case 2 includes a lower cover electromagnetic assembly 22, a spring pin 241, a spring element 25, and a power supply. Thus, when the cover is open, the circuit formed between the upper cover electromagnetic assembly 12, the conductive metal sheet 131, the spring pin 241, and the power supply remains electrically connected, while the circuit formed between the lower cover electromagnetic assembly 22, the metal block 14, the spring element 25, and the power supply is disconnected. When the cover is closed, the circuit formed between the upper cover electromagnetic assembly 12, the conductive metal sheet 131, the spring pin 241, and the power supply remains disconnected, while the circuit formed between the lower cover electromagnetic assembly 22, the metal block 14, the spring element 25, and the power supply remains electrically connected. That is, the circuit between the upper cover electromagnetic assembly 12 and the power supply is connected or disconnected by the contact between the conductive metal sheet 131 and the spring pin 241, while the circuit between the lower cover electromagnetic assembly 22 and the power supply is connected or disconnected by the contact or engagement between the metal block 14 and the spring element 25.

[0053] In this way, when the cover is open, the conductive metal sheet 131 and the metal block 14 both move upward with the upper box body 1 relative to the lower box body 2. During the process, the conductive metal sheet 131 and the upper cover electromagnetic assembly 12 and the power supply are changed from the initial power-off state to the electrically connected state, while the metal block 14 and the lower cover electromagnetic assembly 22 and the power supply are changed from the initial power-on state to the power-off state; at the same time, in the process of sliding assembly of the upper box body 1 relative to the lower box body 2, the power-on and power-off states of the upper cover electromagnetic assembly 12 are freely switched, thereby achieving that in the cover-open state, the overall structure of the earphone 3 can only withstand the first adsorption force of the upper cover electromagnetic assembly 12, the overall structure of the earphone 3 can move with the upper box body 1, and can make the earphone tail 32 extend from the lower box body 2, or can make the earphone tail 32 fall off the lower box body 2, and at least part of the structure of the earphone tail 32 can be convenient for the user to hold. Furthermore, the upper cover electromagnetic assembly 12 is configured to automatically cut off the power and lose the adsorption on the earphone head 31 when the cover is closed, and the lower cover electromagnetic assembly 22 is configured to automatically turn on and form a second adsorption force on the earphone tail 32 when the cover is closed. In this way, in the closed state, the overall structure of the earphone 3 can be stably limited to the lower box body 2 under the action of the second adsorption force, which can help the Bluetooth earphone 3 to be stably in the charging state.

[0054] Considering the installation scheme of the conductive metal sheet 131 and the metal block 14 in the upper cover electromagnetic assembly 12, in the solution of the wireless Bluetooth headset charging box provided in the embodiment of the present application, a connecting plate 13 extends from the side of the upper box body 1 close to the lower box body 2, and the lower box body 2 has a sliding groove 23. The connecting plate 13 slides in conjunction with the sliding groove 23, and the connecting plate 13 is used to install the conductive metal sheet 131 and the metal block 14.

[0055] In this way, during the opening process, it is ensured that when the upper box body 1 moves relative to the lower box body 2 , the connecting plate 13 on which the conductive metal sheet 131 and the metal block 14 are mounted can move upward or downward with the upper box body 1 .

[0056] Exemplarily, the connecting plate 13 can serve as a sliding track of the lower box body 2 , and the sliding groove 23 can serve as a guide groove of the upper box body 1 .

[0057] Since the power supply is generally located in the lower box body 2, considering the circuit connection scheme in the upper cover electromagnetic assembly 12 during the process of opening or closing the cover, in the solution of the wireless Bluetooth headset charging box provided in the embodiment of the present application, the end of the conductive metal sheet 131 close to the upper box body 1 maintains electrical connection with the upper cover electromagnetic assembly 12 in a contact state, and the lower box body 2 is installed with a spring ejector 241; the spring ejector 241 can be directly installed on the lower box body, and the spring ejector 241 can also be installed on the lower box body through a fixing block 243.

[0058] When the lid is closed, a preset distance is left between the conductive metal sheet 131 and the other end of the spring pin 241 in the direction from the upper box body 1 to the lower box body 2, so that they are in a disconnected state; when the lid is open, the conductive metal sheet 131 and the other end of the spring pin 241 remain electrically connected in a contact state, that is, one end of the upper cover electromagnetic assembly 12 is connected to one end of the conductive metal sheet 131, the other end of the conductive metal sheet 131 is connected to one end of the spring pin 241, and the other end of the spring pin 241 is connected to one end of the power supply.

[0059] For example, when the conductive metal sheet 131 includes one, when the cover is open, one end of the upper cover electromagnetic assembly 12 is connected to the end of the conductive metal sheet 131 close to the upper box body 1, the end of the conductive metal sheet 131 away from the upper box body 1 is connected to one end of the spring ejector pin 241, the other end of the spring ejector pin 241 is connected to one end of the power supply, and the other end of the upper cover electromagnetic assembly 12 is connected to the other end of the power supply. In this way, the circuit on the side of the upper cover electromagnetic assembly 12 that is connected to the positive or negative pole of the power supply can be turned on and off by whether the conductive metal sheet 131 is in contact with the spring ejector pin 241.

[0060] For example, two conductive metal sheets 131 may be provided, spaced apart along the length of the lower box body 2. Two spring pins 241 may also be provided, spaced apart along the length of the lower box body 2. When the lid is open, the two ends of the upper cover electromagnetic assembly 12 are connected to the end of each conductive metal sheet 131 that is close to the upper box body 1, and the end of each conductive metal sheet 131 that is away from the upper box body 1 is connected to one end of the corresponding spring pin 241. The other end of each spring pin 241 is connected to the two ends of the power supply. In this way, the power supply connection between the upper cover electromagnetic assembly 12 and the lower box body 2 is more convenient and simple during the process of opening and closing the lid.

[0061] In the closed state, the conductive metal sheet 131 includes a first metal sub-sheet 1311 and a second metal sub-sheet 1312. The first metal sub-sheet 1311 and the second metal sub-sheet 1312 are arranged at intervals. The first metal sub-sheet 1311 and the second metal sub-sheet 1312 are respectively connected to the other end of the corresponding spring pin 241 at a preset distance in the direction from the upper box body 1 to the lower box body 2, so as to be in the disconnected state; in the open state, the first metal sub-sheet 1311 and the second metal sub-sheet 1312 are respectively electrically connected to the other end of the corresponding spring pin 241 in a contact state, that is, one end of the upper cover electromagnetic assembly 12 is connected to one end of the first metal sub-sheet 1311 and the second metal sub-sheet 1312, the other ends of the first metal sub-sheet 1311 and the second metal sub-sheet 1312 are respectively connected to one end of the corresponding spring pin 241, and the other end of the spring pin 241 is connected to one end of the power supply.

[0062] The conductive metal sheets 131 include two, and the two conductive metal sheets 131 are spaced apart along the length direction of the lower box body 2. The spring ejector pins 231 include two, and the two spring ejector pins 231 are spaced apart along the length direction of the lower box body 2. In the open state, the two ends of the upper cover electromagnetic assembly 12 are respectively connected to the end of each conductive metal sheet 131 close to the upper box body 1, and the end of each conductive metal sheet 131 away from the upper box body 1 is connected to one end of the corresponding spring ejector pin 231, and the other end of each spring ejector pin 231 is connected to the two ends of the power supply. Connection; that is, one end of the upper cover electromagnetic assembly 12 is connected to one end of the first metal sub-piece 1311, the other end of the first metal sub-piece 1311 is connected to one end of one of the spring ejector pins 241, the other end of one of the spring ejector pins 241 is connected to one end of the power supply; the other end of the upper cover electromagnetic assembly 12 is connected to one end of the second metal sub-piece 1312, the other end of the second metal sub-piece 1312 is connected to one end of another spring ejector pin 241, the other end of the other spring ejector pin 241 is connected to the other end of the power supply. In this way, the on and off of the circuits on both sides of the upper cover electromagnetic assembly 12 for connecting to the positive and negative poles of the power supply can be achieved by whether the conductive metal sheet 131 is in contact with the spring ejector pins 241.

[0063] When there are two spring pins 241, the two spring pins 241 constitute a spring pin assembly 24. Specifically, the spring pin assembly 24 includes a first spring pin 241A and a second spring pin 241B. The fixing block 243 for limiting the installation of the two spring pins 241 is fixedly installed on the lower box body. One end of the first spring pin 241A is connected to the power supply, and the other end of the first spring pin 241A extends out of the fixing block 243. One end of the second spring pin 241B is connected to the power supply, and the other end of the second spring pin 241B extends out of the fixing block 243.

[0064] In the closed state, the conductive metal sheet 131 is spaced apart from the first and second elastic pins 241A, 241B in the longitudinal direction (which can be understood as a non-contact state), that is, at least part of the conductive metal sheet 131 is located below the first and second elastic pins 241A, 241B. In the open state, as the conductive metal sheet 131 moves upward with the upper box body 1, the conductive metal sheet 131 maintains electrical connection with the first and second elastic pins 241A, 241B, respectively, while in contact. This ensures that the upper cover electromagnetic assembly 12 generates a first adsorption force on the Bluetooth headset when powered. Thus, in the open state, the conductive metal sheet 131 maintains electrical connection with the first and second elastic pins 241A, 241B as it moves with the upper box body 1, while in the closed state, the conductive metal sheet 131 is not electrically connected with the first and second elastic pins 241A, 241B.

[0065] Considering the circuit connectivity scheme of the lower cover electromagnetic assembly 22 in the lower box body 2, in the wireless Bluetooth headset charging box provided in the embodiment of the present application, the bottom surface of the lower box body 2 has a spring 25, one end of the spring 25 is connected to the power supply, and the other end of the spring 25 is electrically connected to the lower cover electromagnetic assembly 22; when the cover is closed, the spring 25 and the metal block 14 maintain electrical connection in a contact state.

[0066] Considering the specific structural scheme of the spring clip 25, in the wireless Bluetooth headset charging case provided in the embodiment of the present application, the spring clip 25 includes two relatively clamping claw edges 251, and at least a portion of the metal block 14 is configured to be detachably clamped between the two claw edges 251. In this way, a deformable space for clamping the metal block 14 is formed between the two claw edges 251. Thus, when the lid is closed, the spring clip 25 is used to clamp the metal block 14, and the conductive properties of metal can be used to achieve an electrical connection between the spring clip 25 and the metal block 14.

[0067] Exemplary, reference Figure 5 The two clamping edges 251 of the spring piece 25 both have chamfered edges that facilitate the metal block 14 to move into the deformable space, and an outer eight structure relative to the deformable space is formed between the two chamfered edges.

[0068] Exemplarily, the elastic sheet 25 may include one or two. When the elastic sheet 25 includes two, the elastic sheet 25 includes a first elastic sheet 25A and a second elastic sheet 25B. The second elastic sheet 25B is spaced apart from the first elastic sheet 25A in the longitudinal direction of the lower box body 2 .

[0069] When two springs 25 are included, when the lid is closed, the first spring 25A and the second spring 25B both clamp the metal block 14, and the metal block 14 conducts electrical signals between the first spring 25A and the second spring 25B. In other words, when the lid is closed, a closed circuit is formed between the power source, the first spring 25A, the metal block 14, the lower cover electromagnetic assembly 22, and the second spring 25B, ensuring that the lower cover electromagnetic assembly 22 generates a second suction force against the earphones 3 when powered.

[0070] Considering the specific structural scheme of the conductive metal sheet 131, in the wireless Bluetooth headset charging case provided in the embodiment of the present application, along the direction from the upper case body 1 toward the lower case body 2, the conductive metal sheet 131 includes an upper vertical sub-segment 131A and an extension portion 131C connected below the upper vertical sub-segment 131A. The upper vertical sub-segment 131A is used to electrically connect with the upper cover electromagnetic assembly 12. When the cover is closed, the extension portion 131C is spaced below the upper case body 1 in the direction pointing toward the lower case body 2, and a spring pin 241 is provided. The metal block 14 is spaced apart from the extension portion 131C. For example, when the cover is open, the extension portion 131C is used to make contact and electrically connect with the spring pin 241.

[0071] Considering the structure of the conductive metal sheet 131, in the wireless Bluetooth headset charging case provided in the embodiment of the present application, the conductive metal sheet 131 may further include an upper vertical sub-segment 131A, a horizontal sub-segment 131B, and a lower vertical sub-segment. The upper vertical sub-segment 131A is used to connect to the upper cover electromagnetic assembly 12, and the extension 131C is constructed as a horizontal sub-segment 131B and a lower vertical sub-segment. When the cover is open, the horizontal sub-segment 131B or the lower vertical sub-segment is used to make electrical contact with the spring ejector pin 241.

[0072] In the wireless Bluetooth headset charging box provided in an embodiment of the present application, when the conductive metal sheet 131 includes two, the spring pin 241 includes a first spring pin 241A and a second spring pin 241B, the conductive metal sheet 131 includes a first metal sub-sheet 1311 and a second metal sub-sheet 1312 spaced apart from the first metal sub-sheet 1311, the first metal sub-sheet 1311 and the second metal sub-sheet 1312 each include an upper vertical sub-segment 131A, a horizontal sub-segment 131B and a lower vertical sub-segment, each upper vertical sub-segment 131A is electrically connected to the upper cover electromagnetic assembly 12, and in the open cover state, the horizontal sub-segments 131B of the two conductive metal sheets 131 are electrically connected to the first spring pin 241A and the second spring pin 241B, or the lower vertical sub-segments of the two conductive metal sheets 131 are electrically connected to the first spring pin 241A and the second spring pin 241B, respectively.

[0073] In the wireless Bluetooth headset charging case provided in the embodiment of the present application, the guide groove of the lower case 2 has a limiting edge at the end near the upper case 1, and the upper case 1 has a blocking edge at the end near the lower case 2 that matches the limiting edge. Thus, with the blocking edge and the limiting edge matched, the upper case 1 will not fall out of the lower case 2.

[0074] Exemplarily, the number of Bluetooth earphones is set corresponding to the number of electromagnets with electromagnetic coils in this solution. When there are two Bluetooth earphones in the earphone charging box, the upper cover electromagnetic assembly 12 may include two electromagnets with electromagnetic coils, and accordingly, the lower cover electromagnetic assembly 22 also includes two electromagnets with electromagnetic coils, where the electromagnetic coils are used to connect to the power supply.

[0075] For example, in the wireless Bluetooth headset charging box of the embodiment of the present application, when two headsets are set, two electromagnets are correspondingly set. The two electromagnets can be set in parallel or in series in the circuit, but the on-off of the circuit adopts the above-mentioned circuit connection schemes, that is, the circuit between the upper cover electromagnetic assembly 12 and the power supply is turned on and off by whether the conductive metal sheet 131 is in contact with the spring pin 241, and the circuit between the lower cover electromagnetic assembly 22 and the power supply is turned on and off by whether the spring sheet 25 is in contact with the metal block 14.

[0076] Exemplarily, the upper cover electromagnetic assembly 12 includes two electromagnets with electromagnetic coils, that is, the upper cover electromagnetic assembly 12 includes a first electromagnet 121 and a second electromagnet 122. Correspondingly, the upper box body 1 includes two first accommodating grooves 15, which are respectively used to accommodate the first electromagnet 121 and the second electromagnet 122. In addition, the lower cover electromagnetic assembly 22 also includes two electromagnets with electromagnetic coils, that is, the lower cover electromagnetic assembly 22 includes a third electromagnet 221 and a fourth electromagnet 222. The third electromagnet 221 correspondingly attracts one earphone, and the fourth electromagnet 222 correspondingly attracts the other earphone.

[0077] The present application does not impose any limitation on the shape and structure of the first accommodating groove 15 , as long as it can stably accommodate the corresponding electromagnet with an electromagnetic coil.

[0078] Considering the magnetic attraction schemes of the upper cover electromagnetic component 12 and the lower cover electromagnetic component 22 for the earphone 3 in different directions, in the wireless Bluetooth earphone charging box provided in the embodiment of the present application, an upper iron block 4 is set on the upper part of the earphone 3, and the upper cover electromagnetic component 12 is used to align with the upper iron block 4 for adsorption; a lower iron block 6 is set on the lower part of the earphone 3, and the lower cover electromagnetic component 22 is used to align with the lower iron block 6 for adsorption.

[0079] Exemplarily, the structural definition of earphone 3 herein is applicable to any earphone 3 structure.

[0080] Further considering the charging function of the wireless Bluetooth headset charging box and the function of energizing the electromagnet, the wireless Bluetooth headset charging box provided in the embodiment of the present application also includes a battery 10.

[0081] Considering the relative positional relationship between each spring clip 25, the power supply, each spring pin 241 and each electromagnet, in the wireless Bluetooth headset charging box provided in the embodiment of the present application, the first spring clip 25A and the second spring clip 25B are installed at positions according to actual application requirements. For example, the first spring clip 25A and the second spring clip 25B are respectively located below the battery.

[0082] For example, in a specific scheme in which the first adsorption force generated by the upper cover electromagnetic assembly 12 acts on the earphone head 31, in the wireless Bluetooth earphone charging box provided in the embodiment of the present application, an upper iron block 4 is provided on the earphone head 31. The upper iron block 4 can be provided on the side of the earphone head 31 away from the earphone tail 32, or on the side of the earphone facing the upper box body. In this way, when the cover is open, the electromagnet in the upper box body 1 can achieve adsorption of the upper iron block 4 when powered, that is, achieve adsorption of the earphone head 31 by the upper cover electromagnetic assembly 12.

[0083] Exemplarily, the upper iron block 4 can be embedded in the earphone head 31 , including a method in which the upper iron block 4 protrudes from the earphone head 31 , or a method in which the upper iron block 4 does not protrude from the earphone head 31 .

[0084] Exemplarily, the overall area of the upper iron block 4 is set to correspond to the cross-sectional area of the electromagnet.

[0085] Exemplarily, the electromagnets in the upper cover electromagnetic assembly 12 can be embedded in the upper box body 1 and respectively communicate with the first accommodating cavity 11 , so as to ensure that the first adsorption force generated by the electromagnet can directly act on the earphone head 31 .

[0086] Considering the specific adsorption scheme of the lower cover electromagnetic assembly 22 relative to the bottom surface of the earphone head 31, the wireless Bluetooth earphone charging case provided in the embodiment of the present application is provided with a lower iron block 6 on the earphone head 31. In this way, when the lid is closed, the lower iron block 6 and the electromagnet in the lower cover electromagnetic assembly 22 are aligned and adsorbed, thereby achieving the alignment and adsorption of the earphone by the lower cover electromagnetic assembly 22 when the lid is closed.

[0087] Exemplarily, the lower iron block 6 can be embedded in a side area of the earphone head 31 facing the lower box body 2; including a method in which the lower iron block 6 protrudes from the earphone head 31, or a method in which the lower iron block 6 does not protrude from the earphone head 31.

[0088] Exemplarily, the overall area of the lower iron block 6 is set to correspond to the cross-sectional area of the electromagnet.

[0089] In this way, it can be ensured that during the sliding movement of the upper box body 1 relative to the lower box body 2, the earphone head 31 in the open state can be stably adsorbed in the upper box body 1, and at the same time, the earphone head 31 in the closed state can be stably adsorbed in the lower box body 2.

[0090] In this way, the wireless Bluetooth headset charging box solution provided by the embodiment of the present application can be used to slide the upper box body 1 relative to the lower box body 2 when the cover is opened. During the process, the earphones 3 can move with the upper box body 1, and the earphones 3 always maintain adsorption force with the upper box body 1. Figure 1-3 Taking the position shown in as an example, the tail 32 of the earphone can be exposed from the lower box body 2, and the user can directly hold the tail 32 of the earphone, which is convenient for taking it out, so as to alleviate the technical problems of difficulty in taking out the earphone 3 in the wireless Bluetooth earphone charging box and easy damage during taking and placing.
