[0030] Example 1

[0031] This embodiment provides a mobile phone case 100, please refer to... Figure 1-3 and Figure 10-11 The phone case 100 includes a housing 110 and a quick-release slot 120.

[0032] Please refer to Figure 1-3 The housing 110 has a receiving cavity 111 for receiving a mobile phone. A quick-release groove 120 is provided at the bottom of the receiving cavity 111. At least one pair of oppositely arranged sidewalls in the quick-release groove 120 are provided with limiting flanges 121. The limiting flanges 121 are used to abut against the locking member 260 exposed at the abutment interface 214 in the lanyard structure 200, so as to lock the lanyard structure 200 in the quick-release groove 120.

[0033] This application provides a limiting flange 121 within the quick-release groove 120 at the bottom of the receiving cavity 111. When the locking member 260 in the lanyard structure 200 is exposed at the abutment interface 214 inside or outside the quick-release groove 120, the limiting flange 121 abuts against the locking member 260, thereby locking the lanyard structure 200 within the quick-release groove 120. The limiting flange 121 has a simple structure, facilitating the disassembly and installation of the lanyard structure 200 while ensuring the secure installation of the lanyard structure 200.

[0034] Please refer to Figure 1 and Figure 3 The quick-release groove 120 is provided through the bottom of the receiving cavity 111, and the limiting flange 121 is provided at the end of the quick-release groove 120 away from the receiving cavity 111.

[0035] By placing the limiting flange 121 at the end of the quick-release groove 120 away from the receiving cavity 111, it can provide a receiving space for the locking member 260 and prevent the locking member 260 from occupying the space of the receiving cavity 111.

[0036] Please refer to Figure 1 The quick-release groove 120 is arranged in a straight line along the length of the housing 110, and the end opposite to the receiving cavity 111 protrudes from the housing 110.

[0037] Similarly, the quick-release groove 120 is protruding on the side of the housing 110 away from the receiving cavity 111, which is also to expand the receiving space of the quick-release groove 120, facilitate the receiving of the hanging rope structure 200, avoid the hanging rope structure 200 occupying the space of the receiving cavity 111, and reduce the thickness of the receiving cavity 111.

[0038] Please refer to Figure 1 The phone case 100 also includes a first magnetic attracting element (not shown). The side of the case 110 opposite to the receiving cavity 111 is provided with a first magnetic attracting groove 112. The first magnetic attracting groove 112 is in the shape of an annulus. The first magnetic attracting element is disposed in the first magnetic attracting groove 112 for attracting with magnetic accessories.

[0039] The first magnetic groove 112 is located on the side of the housing 110 opposite to the receiving cavity 111, and the first magnetic component is placed within the first magnetic groove 112, which can improve the attraction force between the first magnetic component and the magnetic accessory. Furthermore, the circular arrangement of the first magnetic groove 112 enhances the aesthetics of the phone case 100. The first magnetic component facilitates the magnetic attachment of the phone to the magnetic charging dock, improving charging efficiency and preventing slow charging or overheating due to misalignment.

[0040] In this embodiment, the phone case 100 also includes a second magnetic component (not shown), which is disposed on the side of the case 110 away from the receiving cavity 111, and is used to fix the phone case 100 to the magnetic component.

[0041] Since both the first magnetic groove 112 and the first magnetic component are annular structures, for example, when the first magnetic component is attracted to the magnetic charging base, the phone with the phone case 100 may easily slide relative to the magnetic charging base; or, for example, when the phone with the phone case 100 is placed on a car mount, the first magnetic component alone may cause the phone's center of gravity to be unstable. The second magnetic component, however, ensures double attraction, preventing the phone from sliding or falling, while also ensuring the phone remains at a fixed angle.

[0042] In other embodiments, a second magnetic groove (not shown) is also provided on the side of the housing 110 away from the receiving cavity 111. The second magnetic groove and the quick-release groove 120 are arranged side by side in a straight line on the housing 110, and the second magnetic member is disposed in the second magnetic groove.

[0043] Arranging the second magnetic slot and the quick-release slot 120 in a straight line helps to centralize the design of the phone case 100 and improves the overall aesthetics of the phone case 100.

[0044] Please refer to Figure 1-2The phone case 100 also includes an e-ink screen 130, a circuit board 140 (not shown), and an NFC antenna (not shown). The e-ink screen 130, circuit board 140, and NFC antenna are all housed within a receiving cavity 111. The e-ink screen 130 and NFC antenna are electrically connected to the circuit board 140. A display window 1111 is provided at the bottom of the case 110. The display area of ​​the e-ink screen 130 corresponds to the display window 1111. In this embodiment, the display window 1111 is circular, and a first magnetic groove 112 surrounds the periphery of the display window 1111. The NFC antenna is used to receive image signals emitted by the phone's NFC antenna and send the image signals to the circuit board 140. The circuit board 140 controls the e-ink screen 130 to display the image.

[0045] Example 2

[0046] This embodiment provides a hanging rope structure 200. Please refer to [reference needed]. Figure 4-9 The hanging rope structure 200 includes a body 210, an abutment 220, an elastic element 230, a trigger element 240, and a hanging rope 250.

[0047] Please refer to Figure 4 , 6 8, 9, 11. The main body 210 has a movable cavity 211, and at least one pair of opposing sidewalls of the movable cavity 211 are provided with abutment interfaces 214. An abutment member 220 is disposed in the movable cavity 211, and the abutment member 220 has a first abutment surface 2221 at the position facing the abutment interface 214. The first abutment surface 2221 and the movable cavity 211 define an abutment space 223. A locking member 260 is disposed in the abutment space 223. The abutment member 220 can move between a first position and a second position along a direction perpendicular to the bottom wall of the movable cavity 211. An elastic member 230 is disposed in the movable cavity 211, and the two ends of the elastic member 230 abut against the top wall 215 of the movable cavity 211 and the abutment member 220, respectively. The elastic member 230 has a restoring force to push the abutment member 220 to the second position. The trigger 240 is movably disposed within the movable cavity 211 and at least partially protrudes from the body 210. The trigger 240 is linked with the abutment 220 to move the abutment 220 to the first position. The lanyard 250 is detachably connected to the body 210. When the abutment 220 is in the first position, the first abutment surface 2221 releases the locking member 260, and the locking member 260 is entirely located within the abutment space 223 to release the limiting flange 121 of the quick-release groove 120. When the abutment 220 is in the second position, the first abutment surface 2221 abuts against the locking member 260, and the locking member 260 is engaged and partially exposed at the abutment interface 214 to abut against the limiting flange 121 of the quick-release groove 120.

[0048] In this application, the elastic member 230 abuts the abutment member 220 to the second position, thereby causing the first abutment surface 2221 to abut the locking member 260, and causing the locking member 260 to be locked and exposed at the abutment interface 214. This allows the locking member 260 to continuously abut against the limiting flange 121 of the quick-release groove 120 of the phone case 100, thus securely installing the lanyard structure 200 in the quick-release groove 120. When it is necessary to remove the lanyard structure 200 from the quick-release groove 120, the trigger member 240 is activated, causing the trigger member 240 to move the abutment member 220 to the first position. Further force can then be applied to push the locking member 260 into the abutment space 223 by the limiting flange 121, thereby removing the lanyard structure 200 from the quick-release groove 120.

[0049] In this embodiment, the elastic element 230 is a tension spring, which is always in a compressed state, which helps to apply force to the abutment element 220.

[0050] Please refer to Figure 6 The locking element 260 includes a steel ball or a conical short rod. In this embodiment, the locking element 260 is a steel ball, and both the abutment interface 214 and the steel ball are circular, and the diameter of the abutment interface 214 is smaller than the diameter of the steel ball, so that when the abutment element 220 is in the second position, the first abutment surface 2221 abuts against the steel ball and is exposed outside the abutment interface 214.

[0051] The diameter of the abutment 214 is smaller than the diameter of the steel ball, which can prevent the steel ball from detaching from the abutment 214 and the movable cavity 211. In other embodiments, the abutment 214 and the steel ball can also be other shapes, for example, the steel ball can also be elliptical, without being specifically limited.

[0052] In other embodiments, the locking member 260 is a conical short rod with a bottom diameter larger than the size of the abutment interface 214, so that when the abutment member 220 is in the second position, the first abutment surface 2221 abuts against the conical short rod and is exposed outside the abutment interface 214. The circular bottom surface of the conical short rod is positioned facing the first abutment surface 2221.

[0053] Please refer to Figure 4-6 and Figure 11The side wall of the movable cavity 211 is also provided with a support step 216 and an insertion port 217. The trigger 240 is inserted into the movable cavity 211 through the insertion port 217 and overlaps the support step 216. The trigger 240 can slide along the support step 216. The side of the trigger 240 away from the support step 216 has a second abutment surface 2421. The end of the abutment 220 away from the first abutment surface 2221 is provided with an abutment flange 2211, which is located on the side of the trigger 240 away from the support step 216. When the trigger 240 is pushed to slide along the support step 216 into the movable cavity 211, the abutment flange 2211 can slide along the second abutment surface 2421 to push the abutment 220 to the first position.

[0054] More specifically, such as Figure 6 A supporting step 216 is arranged around the inner wall of the movable cavity 211, and a through hole 2161 is formed in the middle of the supporting step 216. Figure 10 The supporting step 216 divides the movable cavity 211 into a linkage cavity 212 and an abutment cavity 213. The abutment member 220 passes through the through hole 2161 from the linkage cavity 212 and extends into the abutment cavity 213. (Example...) Figure 6 The insertion port 217 extends to the entire sidewall of one of the linkage chambers 212, such as... Figure 4-6 and Figure 9 The trigger element 240 extends into the linkage cavity 212 through the insertion port 217. The elastic element 230 and the abutment flange 2211 are both located within the linkage cavity 212. The first abutment surface 2221 is located within the abutment cavity 213. The abutment interface 214 is disposed on the side wall of the abutment cavity 213 and is located within the abutment cavity 213 near the bottom wall. The abutment space 223 is disposed within the abutment cavity 213.

[0055] In this embodiment, as Figure 5 , Figure 9 and Figure 11 On the one hand, the supporting step 216 can support the trigger 240 and the abutment 220 within the movable cavity 211, relatively fixing their positions. Positioning the trigger 240 between the supporting step 216 and the abutment flange 2211 further limits its range of motion. When the trigger 240 moves, the abutment flange 2211, pushed by the second abutment surface 2421, causes the abutment 220 to move along the side away from the abutment cavity 213, allowing the steel ball to enter the abutment space 223.

[0056] In this embodiment, as Figure 5The top wall 215 of the main body 210 is detachably installed with the main body 210. The top wall 215 of the main body 210, together with the supporting step 216 and the side wall of the movable cavity 211, defines the linkage cavity 212. Specifically, the top wall 215 of the main body 210 is fixed to the main body 210 with screws. On the one hand, the detachable installation of the top wall 215 of the main body 210 with the main body 210 facilitates the disassembly and installation of the entire rope hanging structure 200. On the other hand, it also facilitates design and manufacturing.

[0057] In this application, as Figure 11 The elastic member 230 is compressed by the top wall 215 of the main body 210, so that the elastic member 230 is always in a compressed state, and the supporting member and the trigger member 240 are always under force. The trigger member 240 will not slide arbitrarily. Only after the applied force reaches a certain value can the trigger member 240 be triggered to slide.

[0058] Please refer to Figure 4 and Figure 7 The trigger 240 includes a trigger part 241, a linkage part 242, and a limiting part 243 connected in sequence. The second abutment surface 2421 is located at the linkage part 242. The trigger part 241 is exposed outside the body 210. The limiting part 243 includes a limiting stop 2431, such as... Figure 10 When the abutment 220 is in the second position, the limiting block 2431 and the second abutment surface 2421 are located on opposite sides of the limiting flange 121 in the direction of movement of the trigger 240, so as to restrict the trigger 240 from disengaging from the active cavity 211.

[0059] The limiting part 243 also includes a limiting platform 2432. The limiting block 2431 includes two blocks, which are arranged to surround two adjacent peripheral sides of the limiting platform 2432. When the abutting member 220 is in the second position, the abutting flange 2211 is located on the limiting platform 2432. The abutting flange 2211 can conversely limit the limiting block 2431 and the second abutting surface 2421 at the same time, thereby preventing the triggering member 240 from being completely separated from the linkage cavity 212.

[0060] In this application, as Figure 8 The abutment member 220 includes a linkage end 221 and an abutment end 222. The abutment end 222 is disposed within the abutment cavity 213, and the linkage end 221 is disposed within the linkage cavity 212. An abutment flange 2211 is located at the linkage end 221. The linkage end 221 is also provided with a limiting groove 2212. An elastic member 230 is disposed within the limiting groove 2212. The elastic member 230 can be directly placed within the limiting groove 2212. Preferably, the elastic member 230 is connected to the bottom of the limiting groove 2212, with one end of the elastic member 230 abutting against the limiting groove 2212 and the other end abutting against the top wall 215 of the body 210. A first abutment surface 2221 is located at the abutment end 222.

[0061] The first contact surface 2221 includes an inclined surface, a curved surface, or a combination of both. In this embodiment, such as... Figure 8 and Figure 11 The first contact surface 2221 is a combination of an inclined surface and a curved surface, that is, the first contact surface 2221 is composed of an inclined surface and a curved surface connected together.

[0062] By combining the curved surface and the inclined surface, and setting the curved surface away from the bottom of the abutment cavity 213 relative to the inclined surface, the contact area between the first abutment surface 2221 and the circular steel ball can be increased. This helps to fix the position of the steel ball when it is held in the abutment interface 214, prevent the steel ball from sliding, and improve the abutment firmness with the limiting flange 121.

[0063] The second abutment surface 2421 includes an inclined surface, a curved surface, or a combination of both. In the embodiments of this application, the second abutment surface 2421 is an inclined surface, which facilitates the sliding of the abutment flange 2211 on the second abutment surface 2421.

[0064] In this embodiment, the outer wall of the linkage cavity 212 protrudes from the outer wall of the abutment cavity 213, and the hanging rope 250 is arranged around the outer wall of the abutment cavity 213 and fits against the bottom of the linkage cavity 212. The hanging rope 250 can be glued to the bottom of the linkage cavity 212 or fixed by other fixing methods, which is not specifically limited.

[0065] Example 3

[0066] This embodiment provides a mobile phone case component 300. Please refer to [reference needed]. Figure 1 , Figure 4 and Figure 10 The phone case assembly 300 includes the phone case 100 in Embodiment 1 and the lanyard structure 200 in Embodiment 2. The lanyard structure 200 is detachably mounted on the phone case 100.

[0067] More specifically, as mentioned above, when the abutment 220 is in the first position, the abutment cavity 213 is placed into the quick-release groove 120, and then the trigger 240 is released. The elastic member 230 pushes the abutment 220 to the second position, and the first abutment surface 2221 pushes the locking member 260 to the abutment interface 214 and exposes it. At this point, the locking member 260 can abut against the limiting flange 121, and the hanging rope structure 200 is installed in the quick-release groove 120. When the hanging rope structure 200 needs to be disassembled, the trigger 240 is pushed to move towards the linkage cavity 212. The second abutment surface 2421 pushes the abutment flange 2211 to move, and the abutment member 220 moves to the first position. The first abutment surface 2221 releases the locking member 260. Under the abutment force of the limiting flange 121, the locking member 260 can enter the abutment space 223 to release the limiting flange 121. The hanging rope structure 200 can then leave the quick-release groove 120.
