[0035] Figure 1 A perspective view of an ear-hook TWS earphone 100 according to one embodiment of the present disclosure is shown. Figure 1 As can be seen, the earphone 100 includes an earphone body 102, a battery compartment 110, and a removable battery cover 120. The battery compartment 110 is cylindrical and has an axis x. The battery cover 120 is located at one axial end of the battery compartment 110 and is detachably connected to the battery compartment 110. The other axial end of the battery compartment 110 is connected to the earphone body 102 of the earphone 100 via an ear hook 140. The earphone body includes electronic components such as speakers. The battery cover 120 has a slot 122a on its exterior for engaging a tool to rotate the battery cover 120.

[0036] Figure 2 A cross-sectional view of an ear-hook TWS earphone 100 according to one embodiment of the present disclosure is shown. Figure 3 A perspective view of a battery cover 120 according to one embodiment of the present disclosure is shown. Figure 2 As can be seen, the battery 130 is housed in the battery compartment 110 and has a connector 132 for conductive connection with the battery compartment 110 to power the electronic device. The connector 132 is located on one axial end of the battery 130 and has a plurality of contacts 136 (see...). Figure 4 The battery cover 120 is threadedly connected to the battery compartment 110 to form a closed space for accommodating the battery 130. Figure 3More specifically, the battery cover 120 comprises a bottom 122 and a cylindrical side wall 124 protruding axially from the bottom 122, the cylindrical side wall being at least partially provided with an outer thread 124a for connecting with the battery compartment 120. Correspondingly, the battery compartment 110 is provided with an inner thread 110a. In one or more embodiments of the present disclosure, the battery cover 120 can also be provided with an inner thread, and the battery compartment 110 can be provided with a corresponding outer thread. Meanwhile, in the present embodiment, the battery cover 120 is capable of axially fixing the battery 130, so that the plurality of contacts 136 of the battery 130 are connected with the corresponding electrical contacts of the battery compartment 110 to supply power to the electronic device.

[0037] The present utility model provides a simple and reliable detachable battery design for wearable electronic devices. On the one hand, the battery cover 120 is threadedly connected with the battery compartment 110 on the radial outer part, so that the battery cover 120 can be manually or with a simple tool such as a coin to install or disassemble for replacing the battery. On the other hand, the battery cover 120 is axially abutted on the battery 130 on the radial inner part, so that the battery 130 will not fall off and shake in daily use. This design can meet the needs of environmental protection and compliance in the future, and also meet different degrees of waterproof requirements.

[0038] In Figure 2 and 3 In the illustrated embodiment, the battery cover 120 comprises a spring 128, which is at least partially located inside the cylindrical side wall 124 and is compressed axially by the battery 130 when the battery cover 120 is in the connected state, i.e. the battery cover 120 is tightened. The compressed spring 128 can then exert a pushing force on the battery 130 in the direction of the axis x, thereby effectively fixing the battery 130 axially in the battery compartment and preventing the battery 130 from shaking.

[0039] In the present embodiment, the battery cover 120 further comprises a spring cap 126, which is movably connected with the cylindrical side wall 124 in the axial direction and is configured to prevent the spring 128 from being detached from the cylindrical side wall 124. The spring cap 126 has a central part 126' abutting on one end of the spring 128 facing the battery 130, and a side wall 126" extending axially from the outer edge of the central part, which is at least partially inserted into the cylindrical side wall 124 in the axial direction. By providing the spring cap 126, on the one hand, a more uniform pushing force can be applied to the battery 130 to prevent the battery from shaking, and on the other hand, the installation of the spring 128 can be achieved simply and efficiently, because the spring 128 does not need to be fixedly connected to the bottom 122 of the battery cover 120, but only needs to be pressed and installed with the spring cap 126 to achieve the installation of the spring 128.

[0040] Other embodiments are also conceivable for the axial fixation of the battery cover 120 to the battery 130. In one or more embodiments of the present disclosure, the battery cover 120 can also be designed without the spring cap 126. In this case, the spring 128 needs to be fixedly connected to the bottom 122 of the battery cover 120. In this design, the cylindrical side wall 124 of the battery cover 120 can also be designed radially outside the end of the battery compartment 110 and thus have an internal thread. It is additionally noted that the spring 128 shown in this embodiment is a helical spring. In one or more embodiments of the present disclosure, the spring can also be in the form of an elastomer.

[0041] In this embodiment, the side wall 126" of the spring cap 126 is designed to be snap-connected to the cylindrical side wall 124 by elastic deformation during insertion. In one or more embodiments of the present disclosure, the cylindrical side wall 124 is provided with a first protrusion 124b extending radially inwards, and the side wall 126" of the spring cap 126 is provided with a plurality of sections 126a distributed circumferentially and separated from each other by axially extending slots 126c, wherein the plurality of sections 126a are each provided with a second protrusion 126b extending radially outwards, such that the plurality of sections 126a are each moved radially inwards by elastic deformation during insertion. The outer edge of the spring cap 126 is formed with a chamfer 126d, and the force of the first protrusion 124b acting on the chamfer 126d during insertion causes the plurality of sections 126a to elastically deform radially inwards. After insertion, the plurality of sections 126a elastically recover, so that the first protrusion 124b and the second protrusion 126b prevent the spring cap 126 and the spring 128 from being pulled out, wherein the second protrusion 126b can be stopped on the first protrusion 124b in the direction of pull-out. In one or more embodiments of the present disclosure, the first protrusion 124b can be designed as a circular ring or include a plurality of circular arc segments, but the size of the gap between any two circular arc segments does not allow the second protrusion 126b to pass directly, i.e. the side wall 126" of the spring cap must be elastically deformed to be embedded in the cylindrical side wall and cannot be pulled out after embedding. This design can effectively prevent the spring cap 126 from being pulled out from the cylindrical side wall 124 in all directions. In one or more embodiments of the present disclosure, the number of the plurality of sections 126a is at least three, and each is provided with a second protrusion 126b.

[0042] In one or more embodiments of the present disclosure, the spring cap 126 can also be connected to the cylindrical side wall 124 in another way, for example, the first protrusion 124b does not extend over the entire circumference or extends radially inwardly at some circumferential positions for a short distance, so as to have a gap in the circumferential direction, and the second protrusion 126b is arranged to enter the cylindrical side wall 124 through the gap during insertion and stop on the first protrusion 124b in the disengagement direction by rotation. The number of gaps can be multiple, and the number of second protrusions corresponds to the number of gaps, so that multiple connection sites uniformly distributed in the circumferential direction can be achieved. This arrangement can achieve detachable connection of the spring cap and the cylindrical side wall, but it is obvious that the connection reliability is sometimes not as good as the above-mentioned snap connection.

[0043] Figure 3 It can also be seen that the end of the outer thread 124a of the cylindrical side wall 124 close to the bottom 122 is provided with a sealing ring 160, so that when the outer thread 124a is screwed to the bottom, a sealed fixed connection is formed between the battery compartment 110 and the battery cover 120, thereby preventing moisture and the like from entering the closed space for accommodating the battery 130.

[0044] Figure 4 A perspective view of the battery 130 according to an embodiment of the present disclosure is shown. From Figure 4 It can be seen that the battery 130 is provided with a connector 132 for electrically connecting to the electrical connection part of the battery compartment 110 to supply power to the electronic device, the connector 132 is located on the side of the battery 130 away from the battery cover 120, including a battery-side printed circuit board 134 and a plurality of contacts 136 connected thereto, here 3 contacts. The 3 contacts are respectively positive, negative and ground. The electrical connection part of the battery compartment 110 is provided with a battery-compartment-side printed circuit board 114 and 3 spring pins 116 (see Figure 2 ), which are used to axially abut on the plurality of contacts 136 to achieve electrical connection between the battery 130 and the electrical connection part of the battery compartment 110.

[0045] On the outer periphery of the battery 130, Figure 4 a guide groove 132a is provided on the housing of the connector 132, which is open in the mounting direction of the battery 130, and the guide groove is shaped to cooperate with the corresponding part of the battery compartment 110 to ensure the circumferential mounting position of the battery 130, specifically to ensure that the 3 contacts 136 are electrically connected to the 3 spring pins 116 in the correct order. The battery compartment 110 is externally provided with a mark 150 (see Figure 1 ) at the end close to the battery cover 120, and the battery 130 is aligned with the mark 150 when mounted using the guide groove 132a to ensure the circumferential mounting position of the battery 130.

[0046] Figure 5A replacement procedure for the battery 130 according to one embodiment of the present disclosure is shown. When the battery needs to be replaced, the coin 170 is inserted into the catch slot 122a of the battery cover 120 in the direction of the arrow, and the battery cover 120 is unscrewed by rotating the coin 170, and then the old battery 130 is taken out of the battery compartment 110. When installing a new battery, the battery 130 is installed in the opposite direction of the arrow in the right figure, where it should be noted that the guide slot 132a on the battery 130 is aligned with the mark 150 of the battery compartment 110 to ensure that the three contacts 136 are electrically connected to the three spring pins 116 in the correct order. Then, as shown in the left figure, the coin 170 is inserted into the catch slot 122a of the battery cover 120 in the direction of the arrow, and the battery cover 120 is tightened by rotating the coin 170.

[0047] Figure 6 A replacement procedure for the battery 130 according to another embodiment of the present disclosure is shown, where another connector 132' of the battery 130 is shown. The connector 132' is a wire connector in the form of a plug, and accordingly, the battery compartment 110 can be provided with a corresponding wire connector in the form of a socket, which is not shown here. For this design, the guide slot 132a and the mark 150 can be omitted. When installing a new battery, the electrical connection of the plug of the battery to the socket of the battery compartment can be made externally first, and then the battery is inserted into the battery compartment and the battery cover is screwed on.

[0048] It should be noted that the present disclosure is not limited to ear-hanging TWS earphones, but can also be applied to ear-hanging glasses devices, or other suitable small wearable electronic devices. The battery compartment is connected to the earphone body through the ear-hanging part in the exemplary embodiment, and can also be considered to be connected to the body of the glasses device, etc., or it can also be envisaged to be applied to another wearable electronic device provided with a separate battery compartment.
