[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] refer to Figure 1 , Figure 2 and Figure 3The first aspect of this utility model discloses a protective shell 10. In a first embodiment, the protective shell 10 includes a shell 11 and a battery module 12. The shell 11 has a receiving slot 11a for accommodating a wireless earphone 20 and a recess 11b for accommodating a mobile terminal 30. The wireless earphone 20 includes a body 21, charging contacts 22 disposed on the body 21, and flexible ear tips 23. After the wireless earphone 20 is housed in the receiving slot 11a, the flexible ear tips 23 are compressed. The battery module 12 is disposed on the shell 11 and is used to make conductive contact with the charging contacts 22 of the wireless earphone 20 housed in the receiving slot 11a to charge the wireless earphone 20. With the aforementioned protective shell 10, the flexible ear tips 23 are compressed after the wireless earphone 20 is housed in the receiving slot 11a, and the height of the wireless earphone 20 protruding from the protective shell 10 is relatively small. Combined with the method of charging the wireless earphone 20 using charging contacts 22, the use of a Type-C or micro-USB interface can be avoided, further reducing the height of the wireless earphone 20 protruding from the protective shell 10. By setting the battery module 12 inside the housing 11, when the wireless earphone 20 runs out of power, the user can put the wireless earphone 20 into the receiving slot 11a and charge the wireless earphone 20 through the battery module 12. This reduces the frequency of the user charging the wireless earphone 20 with a charger, thereby improving the convenience of use.

[0024] The mobile terminal 30 of this application is not limited to mobile phones and tablets. Different sizes of protective cases 10 can be selected according to different specifications of the mobile terminal 30.

[0025] refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the battery module 12 includes a first battery 121 disposed on the housing 11 and a circuit board 122. The circuit board 122 is electrically connected to the first battery 121 and has a power transmission terminal 1221 for conductive contact with the charging contacts 22 of the wireless earphone 20 housed in the receiving slot 11a. In some embodiments, the battery module 12 may include a circuit board 123 disposed between the first battery 121 and the circuit board 122. One side of the circuit board 123 is electrically connected to the first battery 121, and the other side is electrically connected to the circuit board 122. The circuit board 123 may be provided with functional modules such as charge / discharge control, safety protection, and voltage conversion to further ensure charging safety and optimize charging performance.

[0026] refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the battery module 12 includes a mounting housing 124 connected to the housing 11, and the first battery 121 is disposed within the mounting housing 124. Specifically, as shown... Figure 4As shown, the mounting housing 124 can be rectangular. The mounting housing 124 includes a cover 1241 and a cover plate 1242. The cover 1241 has a mounting groove 12411 on the side facing the mobile terminal 30. The cover 1241 has a mounting portion 12412 at the bottom of the mounting groove 12411. The circuit board 123 has a first mounting hole 1231 that matches the mounting portion 12412. In some embodiments, the width of the cover plate 1242 may not be greater than the width of the mounting groove 12411, so that the cover plate 1242 can be accommodated within the mounting groove 12411. When the battery module 12 is assembled, the first battery 121 can be fixed to the bottom of the mounting groove 12411 by adhesive bonding. After the first mounting hole 1231 of the circuit board 123 matches the mounting portion 12412 of the cover 1241, they can be connected by threaded fasteners such as screws. After the first battery 121 and circuit board 123 are assembled into the mounting groove 12411, the cover plate 1242 can cover the first battery 121 and circuit board 123 and bond it to the cover 1241, thus hiding the first battery 121 and circuit board 123 and sealing the mounting groove 12411, preventing liquid from entering the mounting cavity and causing damage or short circuit to the circuit board 123.

[0027] Furthermore, the battery module 12 includes connection contacts 125 exposed to the mounting housing 124. These contact contacts 125 are electrically connected to the first battery 121 and are used to charge the first battery 121. Specifically, as... Figure 2 As shown, the connection contact 125 can be located on the side of the circuit board 123 away from the mobile terminal 30. The cover 1241 can have a contact hole 12413 that matches the connection contact 125. The connection contact 125 of the circuit board 123 is exposed to the outside through the contact hole 12413 and can be charged by making conductive contact with the connection contact 125 through a matching charger to charge the first battery 121.

[0028] Furthermore, the mounting housing 124 may include a magnetic block 1243, which may be disposed between or around the contact holes 12413. For example, as... Figure 4 As shown, the housing 1241 has a first fixing groove 12414 at the bottom of the mounting groove 12411. The first fixing groove 12414 is located between the contact holes 12413. The magnetic block 1243 can be fixed in the first fixing groove 12414 by gluing or snapping. By magnetically engaging the magnetic block 1243 with the charging terminal of the charger, the charging terminal is fixed, so that the charging terminal can continuously contact the connection contact 125 of the circuit board 123, preventing the charging terminal of the charger from detaching from the connection contact 125 of the circuit board 123 during charging, thus preventing charging interruption.

[0029] refer to Figure 4 and Figure 5In some embodiments, the battery module 12 may include a first magnetic ring 126, and the cover 1241 has a magnetic ring groove 12415 on the side opposite to the first battery 121. The first magnetic ring 126 can be fixed in the magnetic ring groove 12415 by adhesive bonding or snap-fit. The protective case 10 can be magnetically engaged with an accessory (such as a mobile phone holder) equipped with a magnetic structure through the first magnetic ring 126 to fix the protective case 10 together with the mobile terminal 30 inside the protective case 10 to such an accessory.

[0030] refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the housing 11 has a through hole 11c communicating with the groove 11b, the through hole 11c being spaced apart from the receiving groove 11a, and the battery module 12 covering the through hole 11c. Specifically, as shown... Figure 3 As shown, the housing 11 may have a rectangular through hole 11c that matches the shape of the mounting shell 124 of the battery module 12, and the through hole 11c communicates with the groove 11b, to avoid the direct superposition of the thicknesses of the battery module 12 and the housing 11, which would result in the mounting shell 124 protruding too much from the housing 11. The edge of the through hole 11c of the housing 11 may have an overlapping groove 111, and the cover 1241 is provided with an overlapping portion 12416 along the edge. When the cover 1241 of the battery module 12 is assembled into the housing 11, the cover 1241 can pass through the through hole 11c from the side of the housing 11 where the groove 11b is provided, and the overlapping portion 12416 of the cover 1241 is accommodated in the overlapping groove 111 of the housing 11, and the cover 1241 can be fixed to the housing 11 by adhesive bonding.

[0031] Reference 3 and Figure 6In some embodiments, the protective case 10 includes a flip cover 13, which is rotatably connected to the housing 11 and can switch between an open state and a closed state. In the closed state, the flip cover 13 compresses the wireless earphone 20 to compress the flexible ear tips 23. In the open state, the flip cover 13 forms an angle with the housing 11, allowing the wireless earphone 20 to be removed from the receiving slot 11a. After the wireless earphone 20 is housed in the receiving slot 11a, the flip cover 13 can cooperate with the housing 11 or the mobile terminal 30 to reliably confine the wireless earphone 20 within the receiving slot 11a, preventing the wireless earphone 20 from easily detaching from the receiving slot 11a of the protective case 10. After confining the wireless earphone 20 within the protective case 10, the flip cover 13 can compress the wireless earphone 20, compressing the flexible ear tips 23 of the wireless earphone 20, reducing the height of the wireless earphone 20 protruding from the protective case 10, and consequently reducing the height of the flip cover 13 protruding from the protective case 10. In some embodiments, the length of the flip cover 13 is parallel to the width of the mobile terminal 30. The flip cover 13 can be opened and serves as a support structure for the mobile terminal 30, supporting the mobile terminal 30 when it is placed on a table. That is, when the flip cover 13 is open, the mobile terminal 30 can be tilted upright on a support surface such as a table through the flip cover 13 of the protective case 10, so as to facilitate users to watch movies or play games, thereby improving the convenience of use.

[0032] In some embodiments, the flip cover 13 can be made of an alloy material such as stainless steel to achieve relatively high structural strength and ensure the stability of the flip cover 13 support. In other embodiments, the flip cover is only used to fasten the wireless earphones and can be made of a material with lower structural strength, such as plastic, to save costs.

[0033] In some implementations, such as Figure 7 As shown, the mounting shell 124 and the flip cover 13 protrude from the side of the housing 11 away from the groove 11b. When the housing 124 is closed, the height of the mounting shell 124 protruding from the housing 11 is no greater than the height of the flip cover 13 protruding from the housing 11, so as to reduce the adverse effects of the mounting shell 124 and the flip cover 13 on the user's grip and aesthetics.

[0034] refer to Figure 2 and Figure 3In some embodiments, the housing 11 includes a base 112 and a first support frame 113 connected to the base 112. The base 112 has a groove 11b and a through hole 11c, and the first support frame 113 has a receiving groove 11a. In some embodiments, the receiving groove 11a communicates with the groove 11b, and in the closed state, the receiving groove 11a is used to insert a flexible ear cap 23 so that the flexible ear cap 23 presses against the mobile terminal 30, avoiding excessive protrusion of the flip cover 13 from the housing 11 due to the thickness of the ear cap 23. During normal use of the protective case 10, the flexible ear cap 23 of the wireless earphone 20 abuts against the back of the mobile terminal 30 in a compressed state, and the flip cover 13 is rotatably connected to the first support frame 113. In some embodiments, the material of the first support frame 113 can be the same as that of the flip cover 13, for example, both can be alloy materials; the material of the first support frame 113 can also be different from that of the flip cover 13, for example, the flip cover 13 is an alloy material, and the first support frame 113 is a plastic part with high hardness.

[0035] Continue to refer to Figure 2 and Figure 3 In some embodiments, the substrate 112 includes a main shell 1121 and a perimeter shell 1122 extending along the edge of the main shell 1121, the main shell 1121 and the perimeter shell 1122 forming a groove 11b for accommodating the mobile terminal 30. A first support frame 113 may be disposed on the main shell 1121 of the substrate 112, and a circuit board 122 may be disposed on the main shell 1121 of the protective shell 10. The circuit board 122 may be injection molded within the substrate 112 to protect the circuit board 122. Of course, the circuit board 122 may be a flexible circuit board 122 and may be attached to the side of the substrate 112 facing the mobile terminal 30 to reduce processing difficulty. The main shell 1121 and the surrounding shell 1122 may also have multiple functional openings or buttons that cooperate with the mobile terminal 30, such as an opening in the main shell 1121 for accommodating the camera of the mobile terminal 30, and a switch function button in the surrounding shell 1122 for pressing the corresponding switch of the mobile terminal 30, etc.

[0036] refer to Figure 2 and Figure 3 In some implementations, such as Figure 3As shown, the main housing 1121 has a second mounting hole 11211 and connecting holes 11212 spaced around the second mounting hole 11211. The first support frame 113 has a threaded hole 1131 that matches the connecting hole 11212 of the main housing 1121. When the first support frame 113 is assembled to the main housing 1121, the connection can be achieved by threaded fasteners such as screws after the connecting hole 11212 matches the threaded hole 1131. In some embodiments, the first support frame 113 can be integrally formed with the mounting shell 124 to simplify the structure of the first support frame 113 and the mounting shell 124 and improve the connection reliability of the main housing 1121.

[0037] refer to Figure 2 and Figure 3 In some embodiments, the housing 11 may include a hinge 114, which includes a first hinge piece 1141 and a second hinge piece 1142 that are rotatably engaged. One end of the first hinge piece 1141 is connected to the flip cover 13, and one end of the second hinge piece 1142 is connected to the first support frame 113. The other ends of the first hinge piece 1141 and the second hinge piece 1142 are rotatably connected, so that the flip cover 13 can rotate relative to the first support frame 113 to switch between the open and closed states of the flip cover 13. Taking the connection between the flip cover 13 and the first hinge piece 1141 as an example, combined with... Figure 6 The flip cover 13 may include a limiting protrusion 131, and the first hinge piece 1141 may include a limiting hole 11411. Figure 2 The limiting protrusion 131 of the flip cover 13 is glued together after matching the limiting hole 11411 of the first hinge piece 1141.

[0038] refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the power transmission end 1221 has a power transmission contact 12211 exposed to the first support frame 113. When the earphone is closed, the flip cover 13 presses against the wireless earphone 20 to make the charging contact 22 make conductive contact with the power transmission contact 12211. Specifically, the connection contact 125 can adopt a POGO-PIN structure to achieve elastic contact with the charging contact 22 of the wireless earphone 20. The first support frame 113 can have a charging hole 1132 adapted to the POGO-PIN, through which the connection contact 125 of the power transmission end 1221 passes and protrudes from the charging hole 1132. When the wireless earphone 20 is closed, the connection contact 125 of the power transmission end 1221 makes contact with the charging contact 22 of the wireless earphone 20 to achieve charging of the wireless earphone 20. Of course, the wireless earphone 20 may also have a recessed charging slot 24, with the charging contacts 22 exposed at the bottom of the charging slot 24. When the wireless earphone 20 is placed in the receiving slot 11a and the flip cover 13 is closed, the connecting contact 125 enters the charging slot 24, so that the charging contacts 22 and the connecting contact 125 are better aligned, which can ensure the reliability of the conductive contact between the charging contacts 22 and the connecting contact 125.

[0039] refer to Figure 2 , Figure 3 and Figure 6 In some embodiments, the protective shell 10 includes a magnetic element 14 and a magnetic attracting element 15. The magnetic element 14 is disposed on one of the flip cover 13 and the first support frame 113, and the magnetic attracting element 15 is disposed on the other of the flip cover 13 and the first support frame 113. When closed, the magnetic element 14 is attracted to the magnetic attracting element 15. Exemplarily, the magnetic element 14 can be a magnet, or an iron, cobalt, nickel, or alloy magnet; the magnetic attracting element 15 can be a magnet, or an iron, cobalt, nickel, or alloy magnet.

[0040] In some embodiments, for ease of distinction, the magnetic component 15 may include a first magnetic component 151. Two or more magnetic components 14 are provided and fixedly disposed at intervals on the first support frame 113, and two or more first magnetic components 151 are provided and fixedly disposed on the flip cover 13. The magnetic components 14 and the first magnetic components 151 are matched one-to-one. The fixing methods can be varied; for example, the first support frame 113 and the flip cover 13 may each have a second fixing groove (not shown). The magnetic components 14 are fixed in the second fixing groove of the first support frame 113 by snap-fit ​​or adhesive bonding, and the first magnetic components 151 are fixed in the second fixing groove of the flip cover 13 by snap-fit ​​or adhesive bonding, etc. After the flip cover 13 is closed onto the first support frame 113, the magnetic component 14 of the first support frame 113 cooperates with the first magnetic attraction component 151 of the flip cover 13 to limit the flip cover 13 to the first support frame 113, preventing the flip cover 13 from easily separating from the first support frame 113 and causing the wireless earphone 20 set in the receiving groove 11a of the first support frame 113 to fall out. At the same time, the flip cover 13 maintains the squeezing force on the flexible ear cap 23 of the wireless earphone 20, keeping it in a compressed state.

[0041] Continue to refer to Figure 2 , Figure 3 and Figure 6 In some embodiments, the flip cover 13 has a first end 132 and a second end 133, the first end 132 is provided with a first recessed area 1321 and a protrusion 1322, and the second end 133 is provided with a second recessed area 1331; the first support frame 113 has a third end 1133 and a fourth end 1134, the third end 1133 and the fourth end 1134 respectively protrude from the side of the housing 11 away from the groove 11b, and the third end 1133 is provided with a recessed groove 11331; in the closed state, the protrusion 1322 is received in the recessed groove 11331, the flip cover 13 covers the first support frame 113 and fits against the base 112, and the part of the fourth end 1134 protruding from the housing 11 is received in the second recessed area 1331, so that the height of the flip cover 13 protruding from the back of the base 112 in the closed state is small.

[0042] The first recessed area 1321 and the groove 11331 of the flip cover 13 can form a finger groove, making it convenient for users to open the flip cover 13 by applying force with their fingers. Furthermore, on the side of the flip cover 13 facing the wireless earphone 20, the edge of the flip cover 13 is provided with a protruding reinforcing rib 134. The reinforcing rib 134 can extend along the circumferential edge of the flip cover 13, so that the flip cover 13 can be made thinner and the structural strength of the flip cover 13 can be guaranteed, preventing the flip cover 13 from being easily deformed.

[0043] Furthermore, the flip cover 13 and the first support frame 113 can each be rectangular frames. The flip cover 13 includes a cover body 135, and reinforcing ribs 134 are distributed at intervals along the circumferential edge of the cover body 135 and form a cover groove 136 with the cover body 135. Multiple magnetic components 14 are spaced apart inside the cover body 135. When the flip cover 13 is in the closed state, the flip cover 13 covers the first support frame 113 through the cover groove 136, and the first support frame 113 is completely covered under the flip cover 13 through the first recessed area 1321, the second recessed area 1331 and the cover groove 136, thereby reducing the height of the flip cover 13 and the first support frame 113 protruding from the base 112.

[0044] refer to Figure 3 and Figure 6 In some embodiments, the cover 135 of the flip cover 13 may have an earphone opening 1351. When the wireless earphone 20 is stored in the receiving groove 11a and the flip cover 13 is in a closed state, the portion of the wireless earphone 20 protruding from the receiving groove 11a can be accommodated in the earphone opening 1351 and does not protrude from the side of the flip cover 13 away from the mobile terminal 30.

[0045] Furthermore, the magnetic component 15 may include a second magnetic component 152 and a third magnetic component 153. The second magnetic component 152 is fixedly disposed on the protrusion 1322 by snap-fit ​​or adhesive bonding, and the third magnetic component 153 is fixedly disposed on one end of the flip cover 13 near the second recessed area 1331 by snap-fit ​​or adhesive bonding. The wireless earphone 20 is equipped with a structure that cooperates with the second magnetic component 152 and the third magnetic component 153, such as a magnet or iron, cobalt, nickel and their alloys, so that the wireless earphone 20 can be placed on the flip cover 13 first, and after the wireless earphone 20 is initially positioned by the second magnetic component 152 and the third magnetic component 153, it is then snapped into the receiving groove 11a, which improves the convenience of placing the wireless earphone 20 on the flip cover 13 and prevents the wireless earphone 20 from easily coming out of the earphone opening 1351. Moreover, when the flip cover 13 is switched from the closed state to the open state, one end of the wireless earphone 20 can be directly pulled out from the receiving groove 11a, making it convenient for the user to take out the earphone.

[0046] refer to Figure 8 and Figure 9 In the second embodiment, the housing 11 includes a second support frame 115 connected to the base 112, and a bracket 116 rotatably connected to the second support frame 115. The second support frame 115 has a receiving groove 11a, and the bracket 116 can switch between an open state and a closed state. The mobile terminal 30 includes a second magnetic ring 31, and in the closed state, the bracket 116 and the second magnetic ring 31 of the mobile terminal 30 are correspondingly attracted to each other. Specifically, as shown... Figure 9As shown, the bracket 116 and the second support frame 115 can each be approximately circular frame-shaped. The base 112 can have a circular through hole 11c, which communicates with the groove 11b. The base 112 has a first mounting groove 1123 around the through hole 11c and on the side facing away from the mobile terminal 30. The second support frame 115 can be fixed in the first mounting groove 1123 by adhesive bonding or snap-fit. Further, the magnetic member 15 can include a fourth magnetic member 154. The fourth magnetic member 154 can be fixed in the bracket 116 on the side facing the second support frame 115 by snap-fit ​​or adhesive bonding. The bracket 116 cooperates with the second magnetic ring 31 of the mobile terminal 30 through the fourth magnetic member 154, preventing the bracket 116 from easily changing to a flip-up state when it is in the snap-fit ​​state, and at the same time reliably confining the wireless earphone 20 in the receiving groove 11a, preventing the wireless earphone 20 from easily falling out of the receiving groove 11a of the protective shell 10.
