[0032] As a portable energy supply device, batteries have become one of the main energy sources for mobile devices. Due to the limited size of batteries and considerations of product weight, the battery storage capacity is always limited. Therefore, in some application scenarios, batteries need to be replaced to obtain longer battery life.

[0033] In some battery replacement solutions, the battery is fixed by a clip on one side of the battery compartment. Due to the lack of fixing structure and uneven force on the battery, the battery can easily become loose, resulting in power disconnection or poor contact, affecting the normal use of the device.

[0034] Based on this, reference Figure 1 The present application proposes a battery compartment 10, the battery compartment 10 is used to install a battery 11 including a first card slot 111 and a second card slot 112, and the battery compartment 10 may include: a surface shell 103, a bottom cover 104, a bracket 105, and a first mounting plate 101 and a second mounting plate 102 parallel to each other;

[0035] The first mounting plate 101 and the second mounting plate 102 are perpendicular to the bottom cover 104 or the face shell 103, and are arranged between the bottom cover 104 and the face shell 103. The first mounting plate 101, the second mounting plate 102, the bottom cover 104 and the face shell 103 form a cavity 106, and the cavity 106 is used to accommodate the battery 11; the first mounting plate 101 is provided with a lever 1011, and the lever 1011 is rotatably connected to the face shell 103 through a rotating shaft 10112, and one end of the lever 1011 is provided with a first buckle 10111, and the first buckle 10111 extends into the cavity 106 to couple with the first slot 111;

[0036] The bracket 105 spans the cavity 106, and the bracket 105 includes a first end 1051 and a second end 1052 located on both sides of the cavity 106; the first end 1051 of the bracket 105 is provided with a button 10511, and the second end 1052 of the bracket 105 is provided with a second buckle 10521; an elastic member 1012 is provided between the button 10511 and the first mounting plate 101, and the elastic member 1012 is used to push the bracket 105, so as to push the button 10511 away from the first mounting plate 101, and drive the second buckle 10521 to move. 0521 passes through the second mounting plate 102 and extends into the cavity 106 to couple with the second slot 112; the button 10511 is used to compress the elastic member 1012 under the action of external force, push the bracket 105, so as to push the button 10511 close to the first mounting plate 101, and drive the second buckle 10521 to withdraw from the cavity 106 to decouple from the second slot 112, and the bracket 105 moves the lever 1011, and the lever 1011 drives the first buckle 10111 to withdraw from the cavity 106 to decouple from the first slot 111.

[0037] It is understandable that the first mounting plate 101 can be integrally formed with any one of the face cover or the face shell 103, or can be a part independent of the face cover or the face shell 103. Similarly, the second mounting plate 102 can also be integrally formed with any one of the face cover or the face shell 103, or can be a part independent of the face cover or the face shell 103.

[0038] The parallel relationship between the first mounting plate 101 and the second mounting plate 102 is only used to describe the approximate relationship between the two in space. Considering product functions, production, etc., the first mounting plate 101 and the second mounting plate 102 may have an angle within a certain range. Since the first mounting plate 101 and the second mounting plate 102 are plate-shaped as a whole, but may include other structures, the parallel relationship between the first mounting plate 101 and the second mounting plate 102 is not used to limit other structures.

[0039] Through the above scheme, the button 10511 and the second buckle 10521 are arranged on both sides of the cavity 106 by the bracket 105 spanning the cavity 106. Since the button 10511 is also provided with the first buckle 10111 on the same side, a double buckle design is formed on both sides of the cavity 106, which increases the reliability of fixing the battery 11 and reduces the probability of the battery 11 loosening.

[0040] In order to facilitate understanding of the working principle of the battery compartment 10 of the present application, an exemplary top view is shown as follows: Figure 2 , the second buckle 10521 and the button 10511 are both connected to the bracket 105 ( Figure 2 Not shown, can be combined with Figure 1 ) is fixedly connected, so the movement direction of the second buckle 10521 is always the same as the movement direction of the button 10511.

[0041] When no external force is applied, the first clip 10111 and the second clip 10521 are coupled to the corresponding slots, and the elastic member 1012 applies a force to the bracket 105 and the button 10511 and the clip on the bracket 105 away from the first mounting plate 101, so that the second clip 10521 remains coupled to the second slot 112.

[0042] When an external force is applied to the button 10511, the button 10511 pushes the bracket 105 toward the first mounting plate 101, thereby compressing the elastic member 1012. At this time, since the bracket 105 is also provided with a second buckle 10521, the second buckle 10521 gradually moves away from the second mounting plate 102, thereby uncoupling the second buckle 10521 from the second slot 112. At the same time, the lever 1011 also uncouples the first buckle 10111 from the first slot 111 under the action of the button 10511.

[0043] It is understandable that in the present application, the elastic member 1012 is used to provide a force to move the button 10511 away from the first mounting plate 101, so the elastic member 1012 that can provide this force falls within the protection scope of the present application, such as: a spring, a rubber pad, a rubber spring, a rubber sleeve, and other elastic members 1012 that can be replaced.

[0044] Figure 2The structure in which holes are opened on the first mounting plate 101 and the second mounting plate 102 so that the first clip 10111 and the second clip 10521 can extend into the cavity 106 is merely exemplary. In another embodiment of the present application, grooves can be opened on the first mounting plate 101 and the second mounting plate 102. In another embodiment, the first clip 10111 and the second clip 10521 can be extended into the cavity 106 through the installation gaps among the first mounting plate 101, the second mounting plate 102, the face shell 103 and the bottom cover 104.

[0045] In addition to the button 10511 driving the lever 1011 to decouple the first buckle 10111 from the first slot 111 , the present application also designs a structure for maintaining the coupling between the first buckle 10111 and the first slot 111 .

[0046] As in one embodiment, reference may still be made to Figure 2 A torsion spring is installed on the rotating shaft 10112, and the torsion spring is used to drive the first buckle 10111 to extend into the cavity 106 to couple with the first slot 111; the other end of the lever 1011 contacts the side of the bracket 105 close to the elastic member 1012.

[0047] Or, as in another embodiment, refer to Figure 3 The other end of the lever 1011 is slidably connected to the bracket 105 , and the elastic member 1012 is also used to drive the first buckle 10111 to extend into the cavity 106 to couple with the first slot 111 .

[0048] Specifically, the sliding connection between the other end of the lever 1011 and the bracket 105 can be composed of a slider 10113 on the lever 1011 and a slide rail 10512 on the bracket 105. The direction of the slide rail 10512 is perpendicular to the direction in which the elastic member 1012 extends and contracts. Therefore, when the button 10511 drives the bracket 105 to move, the end of the lever 1011 with the slider 10113 can slide along the direction of the slide rail 10512, thereby coupling or decoupling the first buckle 10111 with the first slot 111.

[0049] In addition to the reliability of fixing the battery 11, in actual use, whether the process of removing the battery 11 is convenient also affects the efficiency and use experience of replacing the battery 11. In some solutions, one hand is required to press the button 10511 to release the buckle, and the other hand is required to quickly pull out the battery 11 while releasing the buckle. However, during use, the button 10511 may be stiff and difficult to maintain the pressed state, and a large force and a fast reaction time are required to successfully remove the battery 11. The operation of two hands is very unfriendly to some application scenarios that are not convenient for two-handed operation.

[0050] In this regard, in one embodiment of the present application, reference is made to Figure 4The battery 11 may further include a groove 113 having a protrusion 1131 at the bottom, the depth of the groove 113 inserted into the cavity 106 is greater than the depth of the first card slot 111 or the second card slot 112 inserted into the cavity 106, and the battery compartment 10 may further include:

[0051] A second elastic member 107 is mounted on the front shell 103 or the bottom cover 104 , and is used to apply a force to the battery 11 to exit the cavity 106 ;

[0052] The first buckle 10111 is also used to couple with the protrusion 1131 in the groove 113 after being decoupled from the first slot 111 , so as to fix the battery 11 when the second elastic member 107 pushes the battery 11 out of the cavity 106 .

[0053] When the first clip 10111 is decoupled from the first slot 111, the second elastic member 107 in the compressed state begins to release elastic potential energy, pushing the battery 11 out of the cavity 106, and the pressed elastic member 1012 begins to rebound, and the first clip 10111 enters the cavity 106 again. Since the battery 11 has slid out a distance, the first clip 10111 is coupled with the protrusion 1131 in the groove 113, thereby fixing the battery 11 in the process of the second elastic member 107 pushing the battery 11 out of the cavity 106, that is, fixing the battery 11 in a partially popped-out state.

[0054] In this way, the user does not need to use two hands to operate. When the battery 11 needs to be removed, one hand presses and releases the button 10511, and the elastic member 1012 drives the first buckle 10111 to quickly decouple and couple the first buckle 10111 with the protrusion 1131 in the groove 113 during the ejection of the battery 11. The hand that has released the button 10511 can then pull out the battery 11. It can be released with one button, and the battery 11 can be prevented from being ejected, and can be operated with one hand.

[0055] In addition, the battery 11 is caught during the ejection process, eliminating the need to seize the brief time gap of the operation.

[0056] according to Figure 4 It can be known that the groove 113 with the protrusion 1131 at the bottom can be located on the side corresponding to the first card slot 111, or on the side corresponding to the second card slot 112, or on both sides.

[0057] Therefore, in another embodiment, the battery 11 may further include a groove 113 having a protrusion 1131 at the bottom, and the depth of the groove 113 inserted into the cavity 106 is greater than the depth of the first card slot 111 or the second card slot 112 inserted into the cavity 106. The battery compartment 10 may further include:

[0058] A second elastic member 107 is mounted on the front shell 103 or the bottom cover 104 , and is used to apply a force to the battery 11 to exit the cavity 106 ;

[0059] The second clip 10521 is also used to couple with the protrusion 1131 in the groove 113 after being decoupled from the second slot 112 , so as to fix the battery 11 when the second elastic member 107 pushes the battery 11 out of the cavity 106 .

[0060] For the beneficial effects of the embodiment in which the second buckle 10521 is coupled with the protrusion 1131 in the groove 113 , reference may be made to the embodiment in which the first buckle 10111 is coupled with the protrusion 1131 in the groove 113 , which will not be described in detail here.

[0061] The above two embodiments can be used alone or in combination, and this application does not limit this.

[0062] When pressing the button 10511 , the greater resistance will make it difficult to press the button 10511 , thereby making it difficult to trigger the release action of the first buckle 10111 and the second buckle 10521 .

[0063] In this regard, in another embodiment of the present application, reference is made to Figure 5 The second mounting plate 102 may further include a U-shaped slide rail 1021, and the second end 1052 of the bracket 105 is further provided with a U-shaped slider 10522 coupled to the U-shaped slide rail 1021, and the U-shaped openings of the U-shaped slide rail 1021 and the U-shaped slider 10522 face the direction in which the second buckle 10521 exits the cavity 106.

[0064] Adjusting the elastic force of the elastic member 1012 may affect the effectiveness of the coupling. With the above solution, since the U-shaped opening faces the direction in which the second buckle 10521 exits the cavity 106, when the button 10511 is pressed, that is, when the second buckle 10521 exits the cavity 106, the gradually increasing matching clearance between the U-shaped rail 1021 and the U-shaped slider 10522 reduces the friction force, thereby reducing the friction force when the button 10511 is pressed. The reduction in friction force means that the force required to press the button 10511 becomes smaller, which reduces the difficulty of triggering the release action of the first buckle 10111 and the second buckle 10521 without affecting the coupling.

[0065] The battery 11 usually has polarity distinction. When the electrodes are connected in reverse, the electrical appliance cannot work and may easily cause danger. Based on this, in the present application, among the several surfaces of the cavity 106 that contact the battery 11, at least two opposite surfaces have different shapes.

[0066] Reference to an embodiment Figure 6, is a cross section AA of the battery 11 and the cavity 106. The cross section of the cavity 106 is a trapezoid. It can be seen that the relative top and bottom sides of the trapezoid are of different lengths, which means that the two faces corresponding to the top and bottom sides of the trapezoid are of different shapes. When the battery 11 is rotated 180°, it cannot be inserted into the cavity 106, which achieves foolproofing and avoids the danger caused by reverse insertion of the battery 11.

[0067] In another embodiment, the battery 11 may include a plurality of concave contacts, which are electrically connected to the electrodes of the battery 11 ; the surface shell 103 or the bottom cover 104 includes sheet electrodes, which are in contact with the concave contacts when the battery 11 is installed in the cavity 106 .

[0068] According to the solution of this embodiment, the contacts of the battery 11 are located inside the battery 11, and only the corresponding sheet electrodes can extend into and conduct with the contacts. Even if there is no foolproof structure, reverse insertion of the battery 11 will not cause a short circuit.

[0069] Accordingly, reference Figure 7 The present application also provides a battery 11, which is used to be installed in the battery compartment 10 of any of the above embodiments; the battery 11 includes a first card slot 111 and a second card slot 112; the first card slot 111 is used to couple with the first buckle 10111, and the second card slot 112 is used to couple with the second buckle 10521.

[0070] On this basis, in one embodiment, the battery 11 may further include a groove 113 having a protrusion 1131 at the bottom of the groove; the depth of the groove 113 inserted into the cavity 106 is greater than the depth of the first card slot 111 or the second card slot 112 inserted into the cavity 106; the battery compartment 10 may further include a second elastic member 107 installed on the surface shell 103 or the bottom cover 104;

[0071] The groove 113 is used to couple with the first buckle 10111 after the first buckle 10111 is decoupled from the first slot 111 , so as to fix the battery 11 when the second elastic member 107 pushes the battery 11 out of the cavity 106 .

[0072] In another embodiment, the battery 11 may further include a groove 113 having a protrusion 1131 at the bottom; the depth of the groove 113 inserted into the cavity 106 is greater than the depth of the first card slot 111 or the second card slot 112 inserted into the cavity 106; the battery compartment 10 may further include a second elastic member 107 installed on the surface shell 103 or the bottom cover 104;

[0073] The groove 113 is used to couple with the second clip 10521 after the second clip 10521 is decoupled from the second slot 112 , so as to fix the battery 11 when the second elastic member 107 pushes the battery 11 out of the cavity 106 .

[0074] Accordingly, reference Figure 8The present application also provides a headset 1, which includes: a battery compartment 10 in any of the above embodiments; and a battery 11 installed in the battery compartment 10.

[0075] The embodiments and beneficial effects corresponding to the battery 11 and the headset 1 can refer to the embodiment corresponding to the battery compartment 10 above, which will not be described in detail here.

[0076] Also refer to Figure 8 In one embodiment, the opening of the battery compartment 10 is located on the side of the headset 1 perpendicular to the wearing side; the wearing side is used to fit the user's ear.

[0077] Understandably, Figure 8 The shapes in the figure are only exemplary and are not intended to limit the present application.

[0078] Since the side where the opening of the battery compartment 10 is located is perpendicular to the wearing side, the probability of this side being touched is smaller, so compared with the side opposite to the wearing side where the opening is located, the probability of debris entering can be reduced.
