Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0058] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0059] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0060] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a quick-release device 010, which can be mounted on the protective case 030 of a mobile terminal and used to install other expansion accessories such as a handle 020. Of course, in other embodiments, the quick-release device 010 can also be directly mounted on the mobile terminal, which is not specifically limited here.

[0061] The inventors discovered that the quick-release devices provided by the relevant technologies are not only inconvenient to assemble and disassemble, but also have problems such as unreasonable structural design and large size.

[0062] To improve the above issues, please refer to Figure 5 , Figure 6 and Figure 7 The quick-release device 010 of this embodiment includes a housing 100, a sliding member 300, a pressing member 400, and two clips 200. Each clip 200 includes a clipping portion 210 and a swing portion 220 connected to the clipping portion 210. The swing portion 220 is rotatably mounted to the housing 100. Both clips 200 have an engaged position and an open position. When the two clips 200 are in the engaged position, the clipping portions 210 of the two clips 200 approach each other to engage with the protective shell 030 protecting the outside of the mobile terminal. When the two clips 200 are in the open position, the clip portions 210 of the two clips 200 are far apart from each other to separate from the protective shell 030; the slider 300 is slidably disposed on the shell 100 and is in transmission engagement with the swing portion 220 of the two clips 200; the actuating member 400 is slidably disposed on the shell 100 and is in transmission engagement with the slider 300; wherein, when the actuating member 400 is pressed by an external force, the actuating member 400 can drive the slider 300 to rotate the two clips 200 to the open position.

[0063] The quick-release device 010 can be activated by pressing the actuating element 400, which drives the sliding element 300 to slide. The sliding element 300 then rotates the two clips 200 to the open position, ensuring easy removal of the quick-release device 010 from the mobile terminal or its protective case 030. Since both the sliding element 300 and the actuating element 400 are slidably mounted on the housing 100, a compact structural design can be achieved within the limited space of the housing 100. This optimizes the structure of the quick-release device 010, reduces its size, and makes it easier to carry and use, significantly improving the user experience.

[0064] Optionally, the sliding direction of the pusher 400 is at an angle to the sliding direction of the slider 300; wherein, the pusher 400 is configured to slide into the housing 100 when pressed by an external force, and drive the slider 300 to slide towards the clamp 200, so as to drive the two clamps 200 to rotate to the open position; the direction of the force applied by the slider 300 to the clamp 200 is different from the direction of the force applied by the pusher 400 to the slider 300.

[0065] Since the sliding directions of the slider 300 and the pusher 400 are distributed at an angle, the force transmission direction of the pusher 400 can be changed by the slider 300, so as to achieve a compact structural design within the limited space of the housing 100, optimize the structure of the quick-release device 010, reduce the volume of the quick-release device 010, make it easier to carry and use the quick-release device 010, and greatly improve the user experience.

[0066] Moreover, since only one pusher 400 is needed to drive the slider 300 to slide, thereby rotating the two clips 200 to the open position, the number of pushers 400 is reduced, and the overall size of the quick-release device 010 can also be reduced.

[0067] Meanwhile, the sliding of the slider 300 enables the transmission of force to drive the clip 200 to rotate to the open position. This not only enables the transmission of force within a small space to ensure the compact structural design of the quick-release device 010, but also ensures that the clip 200 can be switched to the open position efficiently and reliably, thereby improving the disassembly efficiency of the quick-release device 010 and enhancing its ease of use.

[0068] It should be noted that the sliding direction of the pusher 400 when pressed is perpendicular to the sliding direction of the slider 300. Of course, in other embodiments, the angle between the sliding direction of the pusher 400 when pressed and the sliding direction of the slider 300 can be 88°, 91°, etc., and is not specifically limited here.

[0069] Alternatively, please refer to Figure 5 , Figure 6and Figure 8 The housing 100 includes an outer shell 110, which includes a front shell 120 and a rear shell 130. The front shell 120 and the rear shell 130 are interlocked and connected to form an assembly cavity. The end of the front shell 120 away from the rear shell 130 has a clamping end with a first clearance hole 121. A swinging part 220 is rotatably disposed within the assembly cavity. At least a portion of the clamping part 210 extends from the first clearance hole 121, facilitating reliable engagement between the clamping part 210 extending from the front shell 120 and the protective shell 030. A sliding member 300 is slidably disposed within the assembly cavity. The arrangement of the front shell 120 and the rear shell 130 facilitates easy assembly of the internal structure of the quick-release device 010; that is, the clamp 200 and the sliding frame can be assembled inside the front shell 120 before connecting the front shell 120 and the rear shell 130.

[0070] Optionally, the clip end is provided with two first clearance holes 121, and the clip portions 210 of the two clips 200 extend out from the two first clearance holes 121 respectively. This arrangement can reduce the size of each first clearance hole 121 so that the size of the first clearance hole 121 only needs to meet the movement of the clip portion 210, which helps to reduce the amount of dust and other substances entering the front housing 120, thereby improving the cleanliness, and reducing the possibility of other objects entering the front housing 120 through the first clearance holes 121, thus improving the problem that the clips 200 are easily damaged by objects entering the front housing 120.

[0071] Alternatively, please refer to Figure 5 , Figure 6 and Figure 8 The housing 100 has a plug-in portion 102; specifically, the clip end of the front housing 120 is also provided with a plug-in portion 102, which is located between two first clearance holes 121 and is used to plug into and cooperate with the protective housing 030; by plugging the plug-in portion 102 into the protective housing 030, the purpose of pre-positioning can be achieved when the quick-release device 010 is assembled into the protective housing 030, so as to ensure the accuracy and efficiency of the position of the quick-release device 010 assembled into the protective housing 030.

[0072] Of course, in other embodiments, the plug-in portion 102 can also be used to plug into a mobile terminal.

[0073] The insertion part 102 can be a positioning post of different shapes that can be selected as needed, such as a positioning post with a waist-shaped cross section, etc., without being specifically limited here.

[0074] The connection methods between the plug part 102 and the front shell 120 include, but are not limited to, integral molding, bonding, and snap-fit.

[0075] Alternatively, please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9The front shell 120 and the rear shell 130 are assembled to form a second clearance hole 131. The pusher 400 is movably disposed in the assembly cavity and can be exposed through the second clearance hole 131. In this way, it is easy to apply force and press the pusher 400 through the second clearance hole 131 to ensure the operability of removing the quick release device 010 from the protective shell 030.

[0076] Of course, in other embodiments, the second clearance hole 131 may be provided on the front shell 120 or the rear shell 130, rather than being formed by splicing the front shell 120 and the rear shell 130.

[0077] Alternatively, please refer to Figure 7 and Figure 9 The inner wall of the front shell 120 is provided with a first sliding groove 122, and the sliding member 300 is slidably inserted into the first sliding groove 122. By providing the first sliding groove 122, the smoothness and stability of the sliding member 300 in the assembly cavity can be improved, and the problem of the sliding member 300 deviating from its path during sliding can be improved.

[0078] Optionally, the inner wall of the front shell 120 is provided with two oppositely distributed first sliding grooves 122, and the slider 300 is slidably inserted into the two first sliding grooves 122; in this way, the stable sliding performance of the slider 300 can be further improved.

[0079] Of course, in other embodiments, the number of first grooves 122 can be one, three, etc., and no specific limitation is made here.

[0080] Alternatively, please refer to Figure 7 , Figure 8 and Figure 9 The front shell 120 and the rear shell 130 are joined to form a second sliding groove 132. The length extension direction of the second sliding groove 132 is perpendicular to the length extension direction of the first sliding groove 122, so that the sliding direction of the pusher 400 is perpendicular to the sliding direction of the slider 300. The pusher 400 is slidably inserted into the second sliding groove 132. In this way, the smoothness and stability of the pusher 400 sliding relative to the shell 100 can be improved.

[0081] Optionally, the front shell 120 and the rear shell 130 are joined to form two second sliding grooves 132, and the two second sliding grooves 132 are distributed opposite to each other, so that the pusher 400 can slidably engage with the two second sliding grooves 132. In this way, the stable sliding performance of the pusher 400 can be further improved.

[0082] Of course, in other embodiments, the number of second grooves 132 may be one, three, etc., and no specific limitation is made here.

[0083] In other embodiments, the second groove 132 may be provided on the front shell 120 or the rear shell 130, rather than being formed by combining the front shell 120 and the rear shell 130.

[0084] In other embodiments, the angle between the length extension direction of the first slide groove 122 and the length extension direction of the second slide groove 132 can also be 88°, 92°, etc., and is not specifically limited here.

[0085] Optionally, the front housing 120 and the rear housing 130 are connected by bolts.

[0086] Of course, in other embodiments, the connection method between the front shell 120 and the rear shell 130 can also be snap-fit, adhesive, etc.

[0087] Alternatively, please refer to Figure 1 , Figure 3 and Figure 4 The quick-release device 010 also includes a damping shaft 900, which is connected to the housing 100. Specifically, the damping shaft 900 can be connected to the end of the rear housing 130 away from the front housing 120 by fasteners such as bolts, and the damping shaft 900 is used to connect other accessories such as the handle 020. The damping shaft 900 can be used to achieve 360° stepless rotation.

[0088] Of course, in other embodiments, the damping shaft 900 can also be connected to the rear housing 130 via snap-fit, threaded connection, or other methods.

[0089] Alternatively, please refer to Figure 5 , Figure 6 and Figure 9 The actuating member 400 is provided with a first inclined surface 401, and the sliding member 300 is provided with a second inclined surface 301. When the actuating member 400 is pressed by an external force, the first inclined surface 401 and the second inclined surface 301 abut and slide to drive the sliding member 300 to slide, and the sliding member 300 drives the two clips 200 to rotate to the open position. The provision of the first inclined surface 401 and the second inclined surface 301 ensures the reliability of the sliding member 300 being driven to slide by the pressed actuating member 400.

[0090] Alternatively, please refer to Figure 5 and Figure 6 One end of the swing part 220 is connected to the clamping part 210 and rotatably connected to the housing 100 via a pin 250; specifically, the swing part 220 is connected to the front housing 120 via the pin 250; the other end of the swing part 220 is in transmission engagement with the sliding member 300. With this arrangement, when the sliding member 300 drives the swing part 220 to rotate around the pin 250, the swing part 220 can reliably drive the clamping part 210 to rotate.

[0091] Optionally, the slider 300 includes two third inclined surfaces 302, which are respectively engaged with the ends of the swing portions 220 of the two clips 200 away from the clip portion 210. The distance between the two third inclined surfaces 302 gradually decreases from the end closer to the clip portion 210 to the end farther from the clip portion 210. When the actuator 400 is pressed by an external force, the actuator 400 can drive the slider 300 to slide closer to the clip 200, so that the two third inclined surfaces 302 respectively push the swing portions 220 of the two clips 200 to swing around the rotation axis of the pin 250, thereby driving the clip portion 210 to rotate. This configuration ensures the reliability of driving the two clips 200 to rotate synchronously to the open position via the slider 300.

[0092] It should be understood that the swing part 220 has a first end and a second end. The first end of the swing part 220 is connected to the clamping part 210, and the first end of the swing part 220 is rotatably connected to the housing 100 through the pin 250. The second end of the swing part 220 is in transmission engagement with the third inclined surface 302. When the actuating member 400 is pressed to drive the sliding member 300 to move towards the clamping part 200, any one of the third inclined surfaces 302 can drive the second end of the swing part 220 corresponding to it to swing around the rotation axis of the pin 250 towards the other swing part 220. The swing part 220 drives the corresponding clamping part 210 to swing away from the other clamping part 210, so that both clamping parts 200 can rotate to the open position.

[0093] Alternatively, please refer to Figure 5 , Figure 6 and Figure 7 The clip 200 also includes a drive shaft 230, which is connected to the end of the swing portion 220 away from the clip portion 210. Specifically, the drive shaft 230 is connected to the second end of the swing portion 220, and the second end of the swing portion 220 is in transmission engagement with the slider 300 via the drive shaft 230. When the actuating member 400 is pressed, driving the slider 300 to move closer to the clip 200, any one of the third inclined surfaces 302 can slide into contact with the drive shaft 230 connected to the corresponding swing portion 220, and the drive shaft 230 drives the second end of the swing portion 220 to swing around the corresponding pin 250 towards the other swing portion 220. The drive shaft 230 ensures the reliability and stability of driving the clip 200 to the open position via the slider 300.

[0094] The connection methods between the clamping part 210 and the swinging part 220 include, but are not limited to, integral molding and bonding. The connection methods between the swinging part 220 and the drive shaft 230 include, but are not limited to, integral molding, plug-in connection and threaded connection.

[0095] In this embodiment, the actuator 400 has a first position and a second position; please refer to... Figure 5 With the pusher 400 in the first position, the two clips 200 are in the engaged position; please refer to... Figure 6 With the push button 400 in the second position, both clips 200 are in the open position; please refer to... Figure 5 and Figure 6 The quick-release device 010 also includes a locking component 500, which is movably disposed in the housing 100 and has a first locked position and a first unlocked position. When the locking component 500 is in the first locked position, it locks the pusher 400 in a second position; when the locking component 500 is in the first unlocked position, it unlocks the pusher 400 from the second position. By setting the locking component 500, the pusher 400 can be locked in the second position, thereby ensuring that the clip 200 can be stably held in the open position. This improves the ease of operation of assembling the quick-release device 010 into the protective housing 030, i.e., it improves the problem that the clip 200 may accidentally return to the engaged position, causing the quick-release device 010 to be obstructed by the clip 200 and unable to be smoothly assembled into the protective housing 030.

[0096] Alternatively, please refer to Figure 6 , Figure 10 and Figure 11 The locking assembly 500 includes a striker 510, which includes a striker body 511 and a limiting portion 512 connected to the striker body 511. The pusher 400 is provided with a first groove 411 and a second groove 412 connected to each other. The outer diameter of the limiting portion 512 is larger than the width of the first groove 411. When the pusher 400 is in the first position, the striker 510 is in the first unlock position, wherein the striker body 511 is inserted into the first groove 411 and the limiting portion 512 abuts against the pusher 400. During the process of the pusher 400 moving from the first position to the second position, the striker body 511 moves from the first groove 411 to the second groove 412. When the pusher 400 is in the second position, the striker 510 moves from the first unlock position to the first lock position, wherein the striker body 511 slides out of the second groove 412 and the limiting portion 512 is inserted into the second groove 412. Since the outer diameter of the limiting part 512 is larger than the width of the first groove 411, when the pusher 400 is in the second position and the limiting part 512 is inserted into the second groove 412, the limiting part 512 cannot enter the first groove 411. The position of the pusher 400 is locked by the limiting part 512 and cannot be reset to the first position. In this way, the limiting part 512 can be used to ensure the stability of the pusher 400 being locked in the second position and to ensure the stability of the clip 200 being locked in the open position by the pusher 400 in the second position and the slider 300 cooperating with the pusher 400.

[0097] Optionally, the first groove 411 has a rectangular cross-section in the direction perpendicular to the sliding direction of the striker body 511 relative to the second groove 412, and the second groove 412 has a roughly circular cross-section in the direction perpendicular to the sliding direction of the striker body 511 relative to the second groove 412. The width of the cross-section of the first groove 411 is smaller than the diameter of the cross-section of the second groove 412. The width of the opening where the second groove 412 and the first groove 411 meet is equal to the width of the cross-section of the first groove 411 and smaller than the outer diameter of the limiting part 512. In this way, it can be ensured that when the limiting part 512 is inserted into the second groove 412, the pusher 400 is reliably locked in the second position.

[0098] The connection methods between the firing pin body 511 and the limiting part 512 include, but are not limited to, integral molding, bonding, and threaded connection.

[0099] In order to ensure that the firing pin body 511 can slide out of the second groove 412 efficiently and the limiting part 512 can slide smoothly into the second groove 412 when the pusher 400 switches to the second position, the locking assembly 500 also includes a first elastic member 520, which is connected between the limiting part 512 and the housing 100. The first elastic member 520 is configured to drive the firing pin 510 to move to the first locking position when the pusher 400 moves to the second position.

[0100] Of course, in other embodiments, the first elastic member 520 may also be connected between the limiting part 512 and the firing pin body 511.

[0101] Optionally, when the pusher 400 is in the first position and the firing pin 510 is in the first unlocked position, the limiting part 512 abuts against the pusher 400, causing the first elastic member 520 to be compressed by the limiting part 512 and the housing 100. When the pusher 400 is in the second position, the limiting part 512 is opposite to the second groove 412 and is no longer abutted by the pusher 400. The first elastic member 520 can extend and reset under its own elastic action to drive the firing pin 510 to slide in the second groove 412, so that the firing pin body 511 slides out of the second groove 412 and the limiting part 512 slides into the second groove 412. In this way, the elastic action of the first elastic member 520 can be used to reliably drive the firing pin 510 to move to the first locked position.

[0102] Of course, in other embodiments, when the actuating member 400 is in the first position and the firing pin 510 is in the first unlocked position, the limiting part 512 abuts against the actuating member 400, and the limiting part 512 and the housing 100 can jointly pull the first elastic member 520. When the actuating member 400 is in the second position, the limiting part 512 is opposite to the second groove 412 and is no longer abutted by the actuating member 400. The first elastic member 520 can retract and reset under its own elastic action to drive the firing pin 510 to slide in the second groove 412, so that the firing pin body 511 slides out of the second groove 412 and the limiting part 512 slides into the second groove 412.

[0103] Alternatively, please refer to Figure 5 , Figure 6 and Figure 8 The housing 100 also includes a top plate 140, which is fitted inside the rear housing 130 and has a positioning hole 141. When the striker 510 is in the first unlocked position, both the limiting part 512 and the first elastic member 520 are embedded in the positioning hole 141, and both ends of the first elastic member 520 are connected to the bottom of the limiting part 512 and the positioning hole 141, respectively. This configuration allows the positioning hole 141 to limit the shape of the first elastic member 520 when it recovers and elongates due to its elasticity, thus improving the problem of bending of the first elastic member 520 and reliably driving the striker 510 to move to the first locked position.

[0104] Of course, in other embodiments, when the firing pin 510 is in the first unlocked position, only the first elastic element 520 is embedded in the positioning hole 141.

[0105] The connection between the top plate 140 and the rear shell 130 includes, but is not limited to, interference fit and bonding.

[0106] Alternatively, please refer to Figure 6When the firing pin 510 is in the first locked position, the end of the firing pin body 511 away from the limiting part 512 protrudes from the clip end. When the firing pin 510 is in the first locked position and the end of the firing pin body 511 away from the limiting part 512 is pressed by an external force, the firing pin 510 can move to the first unlocked position. This configuration allows the quick-release device 010 to be engaged with the protective housing 030. The protective housing 030 then supports the protruding striker body 511 from the clip end, driving the striker 510 to move towards the first unlock position. This unlocks the push button 400, and when the push button 400 is unlocked, the slide 300 and the clip 200 are also unlocked, allowing the clip 200 to return to the engaged position and stably engage with the protective housing 030. Since the protective housing 030 can be used to apply force to the striker 510 directly when the quick-release device 010 is assembled with the protective housing 030, there is no need for additional manual operation to return the striker 510 to the first unlock position. This reduces the operation process and improves the assembly efficiency of the quick-release device 010.

[0107] Alternatively, please refer to Figure 5 and Figure 6 In addition to slidingly engaging with the pusher 400 via the first groove 411 or the second groove 412, the slider 300 is also provided with a first insertion hole 303, into which the striker body 511 can be slidably inserted. This arrangement ensures the stability and reliability of the striker 510's movement between the first unlocked position and the first locked position within the confined space of the housing 100.

[0108] Alternatively, please refer to Figure 5 and Figure 6 The front housing 120 has a second insertion hole 123 at the clip end. The firing pin body 511 is slidably inserted into the second insertion hole 123. When the firing pin 510 is in the first locking position, the end of the firing pin body 511 away from the limiting part 512 extends further out from the second insertion hole 123 to expose the clip end.

[0109] Alternatively, please refer to Figure 5 and Figure 6The second socket 123 is adjacent to the insertion part 102. This arrangement allows the striker 510, located in the first locked position, to extend out of the front housing 120 from the position adjacent to the insertion part 102. When the insertion part 102 is inserted into the protective housing 030, the portion of the striker body 511 extending out of the front housing 120 from the position adjacent to the insertion part 102 reliably abuts against the protective housing 030, so that the striker 510 is reliably reset to the first unlocked position. That is, by setting the second socket 123 adjacent to the insertion part 102, it is ensured that the striker 510, located in the first locked position, is adjacent to the insertion part 102, so as to improve the reliability and smoothness of unlocking the striker 510 and improve the unlocking efficiency of the striker 510 when the quick-release device 010 is assembled into the protective housing 030.

[0110] Alternatively, please refer to Figure 5 , Figure 6 and Figure 12 The quick-release device 010 also includes a second elastic element 420, which is connected between the pusher 400 and the housing 100. The second elastic element 420 is used to reset the pusher 400 when it is not pressed by external force. Specifically, when the pusher 400 moves to the second position under the action of external force, the second elastic element 420 is compressed by the pusher 400; when the striker 510 resets to the first unlocked position, the pusher 400 is no longer locked by the striker 510, the striker body 511 is inserted into the second groove 412, and the pusher 400 can be reset to the first position under the elastic action of the second elastic element 420.

[0111] Optionally, the second elastic element 420 is connected between the pusher 400 and the rear housing 130.

[0112] Of course, in other embodiments, the second elastic member 420 may also be connected between the push member 400 and the front shell 120.

[0113] In other embodiments, when the pusher 400 moves to the second position under the action of an external force, the second elastic member 420 may also be stretched, which is not specifically limited here.

[0114] The connection methods between the second elastic member 420 and the push member 400 and the rear shell 130 include, but are not limited to, abutting, snapping, and bonding.

[0115] To improve the stability, reliability, and ease of resetting the card holder 200 to the engaged position; please refer to... Figure 5 , Figure 6 and Figure 7The quick-release device 010 also includes a third elastic element 240, which is connected between the two swing parts 220. The third elastic element 240 is used to rotate the two clips 200 to the engaged position. When the clips 200 rotate to the open position, the third elastic element 240 is compressed by the two swing parts 220. When the pusher 400 is unlocked and moves to the first position, the slider 300 is no longer locked by the pusher 400, and the clips 200 are reset to the engaged position under the elastic action of the third elastic element 240, pushing the slider 300 to reset.

[0116] Of course, in other embodiments, the third elastic member 240 may also be connected between the two clip portions 210.

[0117] In other embodiments, when the clip 200 rotates to the open position, the third elastic element 240 can also be stretched by the two swing parts 220.

[0118] The third elastic member 240 is connected to the swinging part 220 by means including but not limited to abutting, snapping, and bonding.

[0119] Alternatively, please refer to Figure 5 , Figure 6 , Figure 12 and Figure 13 The quick-release device 010 also includes a locking member 600, which is movably connected to the pusher member 400. The locking member 600 has a second locked position and a second unlocked position. When the locking member 600 is in the second locked position, the pusher member 400 is locked by the locking member 600 in a first position where the two clips 200 are in an engaged position. When the locking member 600 is in the second unlocked position, the pusher member 400 is unlocked by the locking member 600, and the pusher member 400 can move to a second position where the two clips 200 are rotated to an open position under the action of an external force. The locking member 600 helps to improve the problem of the clips 200 accidentally switching to the open position due to accidental activation of the pusher member 400, thereby improving the stability of the quick-release device 010 when engaged with the protective shell 030.

[0120] Optionally, the locking member 600 and the push member 400 are slidably connected via a dovetail groove 630; the housing 100 is provided with a limiting surface 101, and when the locking member 600 is in the second locking position, the locking member 600 abuts against the limiting surface 101; since the locking member 600 abuts against the limiting surface 101, and the locking member 600 and the push member 400 are slidably connected via the dovetail groove 630, when either the locking member 600 or the push member 400 is pressed by an external force, the movement of both the push member 400 and the locking member 600 will be abutted by the limiting surface 101, thus preventing the push member 400 from moving to the second position, thereby ensuring the reliability of locking the push member 400 using the locking member 600.

[0121] Optionally, the limiting surface 101 is disposed on the rear shell 130. Of course, in other embodiments, the limiting surface 101 may also be disposed on the front shell 120.

[0122] Alternatively, please refer to Figure 5 , Figure 6 and Figure 10 The locking member 600 is provided with a dovetail groove 630, and the actuating member 400 includes a transmission part 431 and a rib 432 connected to the transmission part 431. The transmission part 431 is slidably inserted into the second sliding groove 132 and is provided with a first inclined surface 401. The first groove 411 and the second groove 412 are both provided in the transmission part 431. The rib 432 is adapted to the dovetail groove 630 and is slidably inserted into the dovetail groove 630. The mounting hole 402 is provided in the rib 432 and extends to the transmission part 431.

[0123] Of course, in other embodiments, the pusher 400 is provided with a dovetail groove 630, and the locking member 600 is slidably inserted into the dovetail groove 630 via a protruding rib 432 connected thereto.

[0124] Optionally, the quick-release device 010 also includes an elastic component 700 disposed between the locking member 600 and the push member 400, for increasing tactile feedback when the locking member 600 moves relative to the push member 400.

[0125] Alternatively, please refer to Figure 12 The elastic component 700 includes a fourth elastic element 710 and a ball bearing 720; the pusher 400 is provided with a mounting hole 402; the fourth elastic element 710 is disposed in the mounting hole 402, and both ends of the fourth elastic element 710 are connected to the bottom of the mounting hole 402 and the ball bearing 720, respectively. The ball bearing 720 protrudes from the mounting hole 402 and slides in cooperation with the locking member 600. When the locking member 600 slides relative to the pusher 400, the ball bearing 720 can slide on the surface of the locking member 600, and the ball bearing 720 can squeeze the fourth elastic element 710 under the pressure of the locking member 600. At the same time, the ball bearing is held against the surface of the locking member 600 by the elastic action of the fourth elastic element 710, thus forming a certain tactile feedback when the locking member 600 slides relative to the pusher 400.

[0126] Of course, in other embodiments, the mounting hole 402 may be provided in the locking member 600, and the ball 720 may slide with the push member 400.

[0127] Alternatively, please refer to Figure 12The locking member 600 is provided with a first clearance groove 610 and a second clearance groove 620. When the locking member 600 slides to the second locked position, the ball bearing 720 is embedded in the first clearance groove 610; when the locking member 600 slides to the second unlocked position, the ball bearing 720 is embedded in the second clearance groove 620. The first clearance groove 610 and the second clearance groove 620 ensure the stability of the locking member 600 in the second locked position and the second unlocked position, which helps to improve the problem of accidental activation of the locking member 600, causing it to move unintentionally between the second locked position and the second unlocked position.

[0128] The first elastic element 520, the second elastic element 420, the third elastic element 240, and the fourth elastic element 710 include, but are not limited to, springs and elastic rubber blocks.

[0129] Alternatively, please refer to Figure 5 , Figure 6 and Figure 8 The quick-release device 010 also includes a rubber pad 800, which is disposed on the housing 100. Specifically, the rubber pad 800 is disposed on the clip portion 210 of the front housing 120 and surrounds the outer periphery of the insertion portion 102. The insertion portion 102 is used to insert into the protective housing 030, and the rubber pad 800 is used to abut against the protective housing 030. By providing the rubber pad 800, the problem of the quick-release device 010 being snapped into the protective housing 030 by the clip 200 can be improved, and the problem of the disassembly device being easily loosened when snapped into the protective housing 030 can be improved, that is, it plays a role in eliminating play.

[0130] Optionally, the rubber pad 800 is provided with a notch 810 to allow space for the second socket 123.

[0131] Of course, in other embodiments, the quick-release device 010 is directly snapped onto the mobile terminal, the plug-in part 102 is used to be plugged into the mobile terminal, and the rubber pad 800 is used to abut against the mobile terminal.

[0132] The process of assembling the quick-release device 010 into the protective shell 030 in this embodiment includes:

[0133] Switch the locking member 600 to the second unlocked position; press the locking member 600 and the pusher 400 so that the unlocked pusher 400 moves from the first position to the second position; during this process, the pusher 400 drives the slider 300 to move towards the clamp 200 so that the slider 300 drives the clamp 200 to rotate to the open position, and when the pusher 400 moves to the second position, the firing pin 510 can move under the action of the first elastic member 520 so that the end of the firing pin body 511 away from the limiting part 512 extends from the clamp end, and the firing pin 510 locks the position of the pusher 400 so that the clamp 200 is locked in the open position.

[0134] The insertion part 102 is inserted into the protective shell 030, so that the rubber pad 800 abuts against the protective shell 030, and the protective shell 030 abuts against the protruding part of the firing pin body 511, so that the firing pin 510 is reset from the first locked position to the first unlocked position; the pusher 400 is unlocked in the second position, and the pusher 400 is reset to the first position under the action of the second elastic member 420; at the same time, the clip 200 is unlocked, and the clip 200 is reset to the engaged position under the action of the third elastic member 240 to clamp the protective shell 030, and at the same time the clip 200 pushes the slider 300 to reset. After the pusher 400 is reset, the locking member 600 is moved to the second locked position.

[0135] The process of removing the quick-release device 010 from the protective shell 030 in this embodiment includes:

[0136] Move the locking member 600 to the second unlocked position, and then press the locking member 600 and the pusher 400 so that the unlocked pusher 400 moves from the first position to the second position. During this process, the pusher 400 drives the slider 300 to move closer to the clip 200 so that the slider 300 drives the clip 200 to rotate to the open position. When the pusher 400 moves to the second position, the firing pin 510 can move under the action of the first elastic member 520 so that the end of the firing pin body 511 away from the limiting part 512 extends out from the clip end. The firing pin 510 locks the position of the pusher 400 so that the clip 200 is locked in the open position, even if the clip 200 is no longer holding the protective shell 030, so that the quick release device 010 can be removed from the protective shell 030.

[0137] In summary, the quick-release device 010 provided by this utility model can be mounted on a mobile terminal or the protective case 030 of the mobile terminal. Moreover, the internal structure design of the quick-release device 010 is more reasonable, which can reduce the overall size, make it easier to carry and use, and greatly improve the user experience.

[0138] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
