Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a quick-release housing anti-accidental touch device and an electronic device having the device. Background Technology

[0002] Existing consumer electronic devices generally consist of a front panel, a mid-frame, and a back cover. Assembly typically employs a flip-chip method, where the back cover and mid-frame are assembled first, followed by the assembly of PCBA and other components, and finally the front panel is assembled onto the mid-frame. This achieves the requirements of an ultra-thin design, narrow bezel, and dust and water resistance.

[0003] The back cover of existing electronic devices is often fixed to the mid-frame using methods such as adhesive application or backing adhesive, preventing users from quickly disassembling and reassembling the device. When disassembling and reassembling the device for after-sales repair or other situations, specialized adhesive melting equipment is required to melt the adhesive before the electronic device can be disassembled for testing and repair.

[0004] However, the newly issued EU ECO certification requires consumer electronics products such as tablets and mobile phones to meet the requirements of non-destructive quick disassembly and material recycling to facilitate battery recycling, and this certification will be implemented in 2027. Clearly, existing casing fixing methods will not meet the latest certification requirements. Based on industry development needs, the casing assembly methods for consumer electronics products need to be improved.

[0005] Therefore, it is necessary to provide a quick-release housing anti-accidental contact device and electronic equipment that can achieve non-destructive quick disassembly of the entire device to facilitate the recycling of electronic components, in order to solve the above problems. Utility Model Content

[0006] One objective of this utility model is to provide a quick-release shell anti-accidental contact device that enables the whole machine to be disassembled without damage, so as to facilitate the recycling of electronic components.

[0007] Another objective of this invention is to provide an electronic device that enables quick and non-destructive disassembly of the entire device to facilitate the recycling of electronic components.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows: A quick-release anti-accidental contact device for a housing is provided, used to detachably connect a rear cover to a middle frame. The quick-release anti-accidental contact device includes a quick-release mechanism and an ejection mechanism. The quick-release mechanism includes a first latch, which is movably installed within the middle frame along a first direction and is used to detachably engage the rear cover. The ejection mechanism is movably installed within the middle frame along a second direction and is used to eject the rear cover. The second direction intersects with the first direction. When the first latch engages with the rear cover, the rear cover presses against the ejection mechanism to generate pre-pressure. When the first latch slides away from the rear cover, the pre-pressure of the ejection mechanism pushes the rear cover to eject it.

[0009] Preferably, the quick-release mechanism further includes a pin spring and a first elastic element; wherein, the pin spring is fixedly connected to the first buckle, the pin spring has a pushing surface, and the pushing surface can drive the first buckle to move to disengage from the back cover when subjected to force; the first elastic element is connected to the first buckle and / or the pin spring, and when the first buckle moves to disengage from the back cover, the first elastic element can generate an elastic force, and the elastic force of the first elastic element is used to drive the first buckle and / or the pin spring to reset, so that the first buckle engages with the back cover.

[0010] Preferably, the side wall of the middle frame is provided with a pin hole opposite to the push surface. The pin hole acts on the pin spring. The electronic device only needs to have a pin hole, so the appearance changes little and the triggering mechanism is hidden, thereby preventing accidental touch.

[0011] Preferably, the quick-release mechanism further includes a pin bracket, which is fixed to the side wall of the middle frame and has a pin hole opposite to the push surface. When the pin is applied to the push surface through the pin hole, it can drive the pin spring to move, thereby moving the first buckle. The first buckle and the pin spring are hidden inside the middle frame. The pin must pass through the pin hole to trigger the pin spring to release the lock. The triggering mechanism is concealed. Compared with external buttons and other methods, the first buckle of this application has an anti-accidental touch function, the first buckle has stable performance in locking the back cover, and the appearance of the electronic device is minimally altered.

[0012] Preferably, the first buckle includes a first engaging block protruding along the first direction; the rear cover is provided with a second buckle protruding along the second direction, and the second buckle is provided with a slot; the first engaging block is detachably engaged in the slot.

[0013] Preferably, the end of the first engaging block is provided with a first inclined surface; the end of the second latch is provided with a second engaging block protruding along the first direction, and the end of the second engaging block is provided with a second inclined surface that cooperates with the first inclined surface; when the rear cover moves along the second direction, the second inclined surface can press against the first inclined surface, thereby causing the first latch to move against the elastic force of the first elastic element. When the second inclined surface disengages from the first inclined surface, the first engaging block can be engaged in the latch groove under the elastic force of the first elastic element. Thus, by pressing the rear cover against the middle frame, the first latch can be engaged with the second latch, which facilitates pre-fixation during rear cover assembly and makes assembly more convenient.

[0014] Preferably, the quick-release mechanism further includes a base with sliding grooves on both sides. The two sides of the retaining pin spring are slidably engaged in the sliding grooves, and the base is fixed to the middle frame. The base facilitates the assembly and fixing of the quick-release mechanism and also allows for the sliding installation of the retaining pin spring.

[0015] Preferably, the end of the base away from the push surface is further provided with an abutment piece, and the two ends of the first elastic member abut against the abutment piece and the end of the first buckle, respectively.

[0016] Preferably, the ejection mechanism includes an ejection seat and a second elastic element. The ejection seat is movably mounted on the middle frame along the second direction, and the second elastic element is disposed between the ejection seat and the middle frame for ejecting the rear cover out of the middle frame. When the first latch engages with the rear cover, the rear cover pushes the ejection seat into the middle frame and compresses the second elastic element. When the first latch disengages from the rear cover, the second elastic element restores its deformation and drives the ejection seat to reset, thereby ejecting the rear cover. This application provides an ejection mechanism to achieve automatic ejection of the rear cover, eliminating the need for a pry bar to damage the rear shell and requiring no specialized equipment to disassemble the rear cover, thus achieving non-destructive disassembly of the entire machine.

[0017] Preferably, the ejector seat has a limiting portion protruding from it and intersecting the second direction, and the middle frame has a blocking portion that cooperates with the limiting portion. When the second elastic member drives the ejector seat to pop out, the limiting portion and the blocking portion abut against each other to prevent the ejector seat from detaching from the middle frame.

[0018] Preferably, the electronic device further includes at least one third latch, which protrudes from the rear cover along the second direction and has a third engaging block protruding along the first direction. The middle frame has a fourth latch corresponding to the third latch, which has a fourth engaging block that engages with the third engaging block. The third engaging block can be detachably engaged with the fourth engaging block. During rear cover assembly, the third latch pre-fixes the rear cover, making assembly easier and ensuring the final strength of the assembled rear cover to meet the overall drop strength requirements.

[0019] Preferably, the electronic device further includes at least one connecting block, which protrudes from the rear cover along the second direction; the middle frame has a mounting hole corresponding to the connecting block, the connecting block is accommodated in the mounting hole, and the connecting block is fixed to the rear cover and / or the middle frame. The fixing of the connecting block strengthens the assembly of the electronic device, reduces the risk of mechanism failure during drop testing, and meets the overall drop strength requirements.

[0020] Compared with the prior art, the quick-release anti-accidental contact device of this utility model is equipped with a quick-release mechanism and an ejection mechanism. The quick-release mechanism includes a first buckle, which is movably installed in the middle frame along a first direction and can be detachably engaged with the back cover. The ejection mechanism is installed in the middle frame and can move along a second direction. When the back cover is engaged with the first buckle, it squeezes the ejection mechanism to generate pre-pressure. When the first buckle slides away from the back cover, the pre-pressure of the ejection mechanism pushes the back cover to eject it. First, the first latch is hidden inside the middle frame and can only be triggered by a pin. The concealed triggering mechanism prevents accidental activation and ensures stable locking of the back cover. Second, the back cover is automatically ejected by the ejection mechanism, eliminating the need for specialized equipment or a pry bar to damage the back cover. This allows for non-destructive disassembly of the entire device. Finally, removing the back cover allows for the recycling and replacement of electronic components. By pressing the back cover, it can be secured to the first latch, thus pre-fixing the back cover and facilitating its assembly. This enables quick and non-destructive disassembly and installation of the entire device.

[0021] Correspondingly, electronic devices with the quick-release anti-accidental-touch device of this utility model also have the above-mentioned technical effects. Attached Figure Description

[0039] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements. It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Combination Figures 1-17 As shown, the quick-release anti-accidental-touch device 100 for housing provided by this utility model is applicable to electronic device 1. It is used to detachably connect the back cover 200 of electronic device 1 to its middle frame 400 so as to realize the non-destructive quick release of the back cover 200 of electronic device 1, thereby realizing the non-destructive quick release and quick installation of the entire electronic device 1, and meeting the recycling needs of electronic materials.

[0041] In this invention, the electronic device 1 specifically refers to consumer electronic products, such as tablet computers and mobile phones, but is not limited thereto. The electronic device 1 can also be various handheld devices, in-vehicle devices, wearable devices, computing devices, and various forms of user equipment (UE), mobile station (MS), terminal device, etc., which are not specifically limited in this application.

[0042] Continue to combine Figures 1-17 As shown, in this utility model, the back cover assembly in the existing electronic device is split into two parts, namely, a matching back cover 200 and a back shell 300. The back cover 200 is designed as a detachable structure. When it is necessary to disassemble the shell to replace the battery assembly or recycle electronic materials, only the back cover 200 needs to be disassembled.

[0043] In this invention, the electronic device 1 includes a quick-release anti-accidental touch device 100, a back cover 200, a rear shell 300, a mid-frame 400, and an LCM (LCD Module) 500. The LCM module 500 is assembled on one side of the mid-frame 400 in a conventional manner. The back cover 200 and the rear shell 300 are combined and then assembled on the other side of the mid-frame 400. The rear shell 300 is fixedly connected to the mid-frame 400, while the back cover 200 and the mid-frame 400 are detachably connected via the quick-release anti-accidental touch device 100.

[0044] Combination Figures 1-5 As shown, in this utility model, the rear shell 300 has a base plate 310 and a frame 320 connected to the base plate 310. The base plate 310 has a hollow structure. The rear cover 200 has a plate-like structure and is assembled onto the base plate 310, thereby combining the rear cover 200 and the rear shell 300 to form a rear shell assembly for mounting the middle frame 400. Specifically, the middle frame 400 is assembled inside the rear shell 300, so that one side of the middle frame 400 fits against the base plate 310, such as... Figure 2 As shown, the back cover 300 and the middle frame 400 are fixed together by adhesive, although other methods can also be used. The back cover 200 is assembled to the outside of the back cover 300, and the back cover 200 and the middle frame 400 are detachably connected by the quick-release anti-accidental contact device 100. Thus, when it is necessary to disassemble the housing of the electronic device 1, for example, when the battery assembly needs to be replaced, the back cover 200 can be disassembled without damage by releasing the quick-release anti-accidental contact device 100. The state of the back cover 200 after disassembly is as follows. Figure 2 As shown, the battery assembly can be replaced at this point, facilitating battery recycling. After replacement, the back cover 200 can be easily reassembled onto the middle frame 400, as shown. Figure 1 As shown.

[0045] The following is combined Figures 2-6 As shown, in one embodiment of this utility model, the quick-release anti-accidental contact device 100 includes a quick-release mechanism 110 and an ejection mechanism 120. The quick-release mechanism 110 includes a first latch 111, which is movably mounted on the middle frame 400 along a first direction (X direction) and protrudes from the middle frame 400. Figure 2 As shown, the first latch 111 is used to detachably engage the rear cover 200. The ejection mechanism 120 is mounted on the middle frame 400 and is movable along the second direction (Z direction). The ejection mechanism 120 also protrudes from the middle frame 400, as shown. Figure 2 As shown, it is used to push the back cover 200. The second direction intersects with the first direction. In this embodiment, the first direction is the width or length direction of the electronic device 1, and the second direction is the thickness direction of the electronic device 1. Of course, the first direction and the second direction can also be other directions.

[0046] The following is combined Figure 2-3 , Figure 5 As shown, in one embodiment, the middle frame 400 has a first mounting hole 410 and a second mounting hole 420 extending through its thickness direction, which are arranged adjacent to each other, but this is not a limitation. The quick-release mechanism 110 is installed in the first mounting hole 410, thereby exposing the first buckle 111 in the middle frame 400, as shown. Figure 2-3As shown. The ejection mechanism 120 is installed in the second mounting hole 420 and protrudes from the middle frame 400, as... Figure 2-3 As shown. Therefore, when the rear cover 200 moves along the second direction and presses against the middle frame 400, the rear cover 200 can press against the ejection mechanism 120 to generate pre-pressure, and finally cause the rear cover 200 to engage with the first buckle 111 and be fixed. At this time, the rear cover 200 always presses against the ejection mechanism 120 to maintain the pre-pressure. When the first buckle 111 slides away from the rear cover 200, the rear cover 200 loses its fixing force. At this time, the pre-pressure of the ejection mechanism 120 will push the rear cover 200 away from the middle frame 400, thereby ejecting the rear cover 200. The user can easily remove the rear cover 200 without professional equipment or a pry bar to damage the rear cover 200 and the rear shell 300, achieving non-destructive quick removal of the shell.

[0047] See Figure 2-3 As shown, in this embodiment, the bottom plate 310 of the rear shell 300 has a first through hole 311 and a second through hole 311 respectively corresponding to the positions of the first mounting hole 410 and the second mounting hole 420. Therefore, after the rear shell 300 and the middle frame 400 are assembled, at least the first buckle 111 of the quick-release mechanism 110 is exposed through the first through hole 311, as shown. Figure 2 As shown, it can be snapped into the back cover 200, while the ejection mechanism 120 is exposed through the second through hole 311, as... Figure 2 As shown, it is able to push the back cover 200. Of course, in some embodiments, if the positions of the first mounting hole 410 and the second mounting hole 420 correspond to the hollow positions on the base plate 310, then it is not necessary to open the first through hole 311 and the second through hole 311.

[0048] The following is combined Figure 3 , Figures 6-11 As shown, in one embodiment of this utility model, the quick-release mechanism 110 further includes a pin spring 112 and a first elastic element 113. The pin spring 112 is fixedly connected to the first latch 111 and has a pushing surface 1121. When the pushing surface 1121 is subjected to force, it can drive the first latch 111 to move and disengage from the rear cover 200. The first elastic element 113 is connected to the first latch 111 and / or the pin spring 112. When the first latch 111 moves away from the rear cover 200, the first elastic element 113 can deform. The elastic force generated by the deformation of the first elastic element 113 is used to drive the first latch 111 and / or the pin spring 112 to reset, thereby automatically engaging the first latch 111 with the rear cover 200 and connecting the rear cover 200 to the middle frame 400.

[0049] Combination Figure 6-7 , Figure 10-11As shown, in one specific embodiment, the first elastic element 113 is located at the end away from the pushing surface 1121, and the first elastic element 113 abuts against the first latch 111. Therefore, when the pushing surface 1121 is subjected to force and drives the first latch 111 to move, the first latch 111 squeezes the first elastic element 113, causing it to undergo elastic deformation. When the pushing surface 1121 loses force, the elastic force of the first elastic element 113 drives the first latch 111 and the pin spring 112 to move synchronously and reset, thereby allowing the first latch 111 to re-engage with the rear cover 200. Of course, the installation method of the first elastic element 113 is not limited to that in this embodiment; for example, abutting it against the pin spring 112 can also achieve the reset function.

[0050] In this invention, the first elastic element 113 is preferably a spring, but it is not limited to this and can of course be other elastic elements.

[0051] Continue to combine Figure 6-7 As shown, in this embodiment, one end of the first latch 111 has a protruding first engaging block 1111, and the other end of the first latch 111 has a protruding positioning post 1113. The first engaging block 1111 and the positioning post 1113 protrude in opposite directions. After the first latch 111 is fixed to the pin spring 112, the first engaging block 1111 is located above and spaced apart from the pin spring 112, so as to be separably engaged with the rear cover 200. The positioning post 1113 protrudes from the end of the pin spring 112, and the first elastic member 113 is sleeved on the positioning post 1113 and abuts against the end of the first latch 111. Furthermore, the end of the first engaging block 1111 is also provided with a first inclined surface 1112, which is specifically provided on the side of the first engaging block 1111 away from the pin spring 112. When the first inclined surface 1112 is subjected to force, it can drive the first latch 111 to move against the elastic force of the first elastic element 113, thereby making the installation of the rear cover 200 more convenient. When the locking pin spring 112 is subjected to force, it can drive the first latch 111 to move against the elastic force of the first elastic element 113 and disengage from the rear cover 200, thereby releasing the lock on the rear cover 200. During the movement of the first latch 111, the first elastic element 113 will be compressed to deform it. The positioning post 1113 positions the first elastic element 113, making it less prone to tilting during compression, thereby ensuring that the elastic force of the first elastic element 113 when restoring its deformation is stable, thus stabilizing the force pushing the first latch 111 back to its original position.

[0052] In this embodiment, the first buckle 111 further has a first fixing part 1114 with a plate-like structure, and the first engaging block 1111 and the positioning post 1113 are respectively protruding from both ends of the first fixing part 1114. The first fixing part 1114 is stacked with the pin spring 112 and fixedly connected by a fastener (e.g., a screw), thereby enabling the pin spring 112 to drive the first buckle 111 to move synchronously.

[0053] Continue to combine Figure 6-7 As shown, in this embodiment, the pin spring 112 further includes a fixing surface 1122 that is bent relative to the pushing surface 1121, and the fixing surface 1122 is preferably perpendicular to the pushing surface 1121. The first fixing part 1114 of the first latch 111 overlaps with the fixing surface 1122, and then the two are fixed by a fastener. At the same time, the first engaging block 1111 is spaced apart from the fixing surface 1122, so that the first engaging block 1111 can engage with the rear cover 200. When the pushing surface 1121 is subjected to force, it will push the pin spring 112 to move, thereby causing the first latch 111 to move synchronously so that the first engaging block 1111 disengages from the rear cover 200, as detailed below.

[0054] The following is combined Figure 2-3 , Figure 5 As shown, in one embodiment of this utility model, the side wall of the middle frame 400 is provided with a pin hole communicating with the first mounting hole 410. When the quick-release mechanism 110 is installed in the first mounting hole 410, the push surface 1121 is opposite to the pin hole. In this way, the pin can act on the push surface 1121 by passing through the pin hole, thereby pushing the pin spring 112 to move in the first direction. With this structure, only the pin hole needs to be opened on the appearance of the electronic device 1, with little change in appearance. The first buckle 111 and the pin spring 112 are both hidden inside the middle frame 400, so the triggering mechanism is concealed and can play a role in preventing accidental touch.

[0055] The following is combined Figure 1-3 , Figure 5-7 , Figure 9-10As shown, in a preferred embodiment of this utility model, the quick-release mechanism 110 further includes a pin holder 114, on which a pin hole 1141 is provided. The pin holder 114 is fixed to the side wall of the middle frame 400 and the pin hole 1141 is opposite to the push surface 1121. Therefore, after the pin passes through the pin hole 1141 on the pin holder 114, it can also act on the push surface 1121, thereby driving the pin spring 112 to move and thus driving the first latch 111 to move. The design of the pin holder 114 allows the first latch 111 and the pin spring 112 to be hidden inside the middle frame 400. The triggering mechanism is concealed, and the pin spring 112 can only be triggered by the pin passing through the pin hole 1141 with a small diameter to achieve the release. Compared with external buttons and other methods, this structural design has a better anti-accidental touch function, making the performance of the first latch 111 engaging the back cover 200 stable. At the same time, the pin holder 114 also makes the appearance of the electronic device 1 more beautiful.

[0056] The following is combined Figure 5-7 , Figure 9-10 As shown, in one embodiment of this utility model, the quick-release mechanism 110 further includes a base 115 and a clamping plate 116. The base 115 has two parallel sliding grooves 1151 on both sides, and a contact piece 1152 protrudes from one end of the base 115. The protruding direction of the contact piece 1152 is perpendicular to the axial direction of the sliding grooves 1151, and a through hole is formed on the contact piece 1152. The two sides of the retaining pin spring 112 are slidably engaged within the two sliding grooves 1151; specifically, the two sides of its fixing surface 1122 are slidably engaged within the two sliding grooves 1151. The pushing surface 1121 of the retaining pin spring 112 is located at the end of the base 115 away from the contact piece 1152. Meanwhile, the positioning post 1113 of the first buckle 111 is movably inserted into the through hole on the abutment piece 1152, and the two ends of the first elastic member 113 abut against the end of the first buckle 111 and the abutment piece 1152 respectively. The base 115 serves two purposes: firstly, it guides the movement of the pin spring 112 using the two sliding grooves 1151; secondly, it facilitates the installation and positioning of the first elastic member 113. Understandably, it is also feasible for the other end of the first elastic member 113 to abut against the abutment piece 1152 directly, rather than against the middle frame 400.

[0057] In this embodiment, the base 115 is fixed to the clamping plate 116, and the method of fixing the two is not specifically limited. The entire quick-release mechanism 110 is fixed to the middle frame 400 by the clamping plate 116, such as... Figure 5 As shown, this makes the assembly and fixing of the quick-release mechanism 110 more convenient.

[0058] Preferably, the clamping plate 116 is a steel plate to increase the installation strength of the quick-release mechanism 110, but it is not limited to this and other plates with sufficient hardness are also feasible.

[0059] The following is combined Figure 3 , Figure 5-7 As shown, when the quick-release mechanism 110 of this application is assembled on the middle frame 400, the entire quick-release mechanism 110 is inserted into the first mounting hole 410 from the inside of the middle frame 400. Specifically, in the first direction (X direction), the first elastic member 113 is located inside the middle frame 400, the pushing surface 1121 of the pin spring 112 is close to the side wall of the middle frame 400, and the pin bracket 114 is snapped or fixed on the side wall of the middle frame 400, so that the pin spring 112 and the first buckle 111 can move along the first direction, such as... Figure 3 As shown. In the second direction (Z direction), the first buckle 111 is located on the outer side of the middle frame 400 (the side that mates with the back cover 200), and the first buckle 111 protrudes from the middle frame 400 through the first mounting hole 410, as shown. Figure 2-3 As shown, it can be snapped into the back cover 200; the clamping plate 116 is attached to the inner side of the middle frame 400, and then the clamping plate 116 is fixed to the middle frame 400 using screws and other fasteners, as shown. Figure 5 As shown.

[0060] Combination Figure 2 As shown, after the rear shell 300 and the middle frame 400 are assembled, the first buckle 111 is exposed through the first through hole 311 on the rear shell 300, so that the first buckle 111 can be engaged with the rear cover 200, as detailed below.

[0061] The following is combined Figure 2-3 , Figure 6 , Figure 12-14 As shown, in one embodiment of this utility model, the ejection mechanism 120 includes an ejection seat 121 and a second elastic member 122. The ejection seat 121 is movably mounted in a second mounting hole 420 on the middle frame 400, and the ejection seat 121 can move along a second direction. The second elastic member 122 abuts against the ejection seat 121 and the middle frame 400, and the elastic force of the second elastic member 122 causes the ejection seat 121 to protrude beyond the middle frame 400, such as... Figure 3 As shown. When the rear cover 200 moves against the middle frame 400, the rear cover 200 pushes the ejector seat 121 into the middle frame 400 and compresses the second elastic member 122. When the first buckle 111 engages with the rear cover 200, the second elastic member 122 is in a compressed state, as shown. Figure 13 As shown. When the first latch 111 disengages from the rear cover 200, the ejector seat 121 loses its resistance, and the second elastic element 122 restores its deformation, driving the ejector seat 121 to reset, thereby ejecting the rear cover 200, as shown. Figure 14 As shown. This application sets up an ejection mechanism 120 to achieve automatic ejection of the rear cover 200, eliminating the need for a pry bar to damage the rear shell 300 and requiring no special equipment to disassemble the rear cover 200, thus achieving the requirement of non-destructive disassembly of the entire machine.

[0062] Continue to combine Figure 6 , Figure 13-14 As shown, the ejector seat 121 has a protruding limiting portion 1211 that intersects with the second direction, and the middle frame 400 has a blocking portion 421 that cooperates with the limiting portion 1211. More specifically, the blocking portion 421 is provided on the inner wall of the second mounting hole 420. The ejector seat 121 passes through the second mounting hole 420, and its limiting portion 1211 and blocking portion 421 are detachably abutted. It is understood that the blocking portion 421 is not limited to this arrangement. Therefore, when the second elastic member 122 drives the ejector seat 121 to pop out, its limiting portion 1211 abuts against the blocking portion 421, as... Figure 14 As shown, to prevent the ejector seat 121 from detaching from the middle frame 400, the end of the ejector seat 121 can pass through the second mounting hole 420 to push the rear cover 200. Traditional ejection mechanisms generally adopt an external switch form, which does not meet the ID requirements in terms of appearance, and also has a high space occupation, which does not meet the design requirements for the thickness of the flat plate. However, the ejection mechanism 120 of this application is built into the middle frame 400 and located inside the rear cover 200, which not only occupies less space and does not increase the thickness of the electronic device 1, but also makes the appearance of the electronic device 1 simpler and more beautiful.

[0063] The following is combined Figure 5-6 , Figure 12-14 As shown, in this embodiment, the ejection mechanism 120 further includes a fixing plate 123, which is fixed to the inner side of the middle frame 400 and covers the top of the second mounting hole 420. Figure 5 As shown, this creates a moving space for the ejector seat 121 between the fixing plate 123 and the blocking part 421. When the ejector seat 121 is pushed into the middle frame 400 by the rear cover 200, the limiting part 1211 of the ejector seat 121 abuts against the fixing plate 123, as shown. Figure 13 As shown, the position of the ejector seat 121 is restricted by the fixing plate 123. The fixing plate 123 is used to fix the entire ejection mechanism 120 and restrict the position of the ejector seat 121, making the installation of the ejector seat 121 more convenient. Of course, other structures can also be used to restrict the position of the ejector seat 121.

[0064] In this invention, the fixing plate 123 is preferably a steel plate, the ejector seat 121 is preferably formed of steel sheet, and the second elastic element 122 is preferably a spring. Of course, other materials and other elastic elements can also be used.

[0065] The following is combined Figure 3, Figure 5-7 , Figure 13-14 As shown, when the ejector mechanism 120 of this application is assembled into the middle frame 400, the ejector seat 121 is first installed from the inside of the middle frame 400 into the second mounting hole 420. Then, the second elastic member 122 is housed in the ejector seat 121. Next, the fixing plate 123 is placed over the second mounting hole 420, and the fixing plate 123 is fixed to the middle frame 400 using screws or other fasteners, thus completing the assembly of the ejector mechanism 120. The assembly of the ejector mechanism 120 is convenient and quick. After assembly, the ejector seat 121 can move along the second direction (Z direction) to protrude from the middle frame 400 or retract into the middle frame 400, such as... Figure 13-14 As shown.

[0066] The following is combined Figure 4 , Figure 9-11 As shown, in one embodiment of this utility model, a second buckle 210 is provided on the back cover 200 at a position corresponding to the quick-release mechanism 110. The second buckle 210 protrudes in a direction that intersects with the surface of the back cover 200, and a slot 210a is provided on the second buckle 210. The second buckle 210 is detachably engaged with the first buckle 111, specifically, the first engaging block 1111 of the first buckle 111 is detachably engaged in the slot 210a, so as to realize the locking and unlocking of the back cover 200.

[0067] See Figure 10-11 As shown, the second latch 210 includes a second engaging block 211 and a first connecting portion 213. The second engaging block 211 protrudes from the end of the first connecting portion 213. The first connecting portion 213 is fixed to the rear cover 200 or integrally formed with the rear cover 200. The second engaging block 211 and the rear cover 200 form the latch groove 210a. More preferably, the end of the second engaging block 211 is provided with a second inclined surface 212, which is located on the side away from the latch groove 210a. The second inclined surface 212 cooperates with the first inclined surface 1112 on the first latch 111. When the rear cover 200 is assembled on the middle frame 400, the rear cover 200 moves in the second direction, at which time the second latch 210 protrudes in the second direction. When the second inclined surface 212 on the second buckle 210 presses against the first inclined surface 1112, the first buckle 111 can overcome the elastic force of the first elastic element 113 and move along the first direction; when the second inclined surface 212 disengages from the first inclined surface 1112, the first engaging block 1111 engages in the slot 210a under the elastic force of the first elastic element 113, as shown. Figure 10As shown, the back cover 200 is assembled. Therefore, by simply moving it towards the middle frame 400 and pressing the back cover 200, the second buckle 210 on it can engage with the first buckle 111 of the quick-release mechanism 110, making the assembly of the back cover 200 more convenient. Moreover, the engagement of the second buckle 210 with the first buckle 111 also serves as a pre-fixing effect for further securing the back cover 200.

[0068] Combination Figure 4 , Figure 10-11 As shown, in a preferred embodiment of this utility model, in order to meet the different material requirements of the back cover 200, such as sheet metal or alloy, the second buckle 210 can be designed separately or integrally formed with the back cover 200. For example, when the back cover 200 is made of composite sheet metal, the second buckle 210 needs to be formed separately and then fixed to the back cover 200 by dispensing glue; when the back cover 200 is made of plastic, the second buckle 210 can be directly injection molded, that is, integrally formed with the back cover 200.

[0069] More preferably, the second buckle 210 further includes a plate-shaped second fixing part 214, with the first connecting part 213 protruding vertically from the second fixing part 214. The second engaging block 211 is bent and protrudes relative to the first connecting part 213, thus forming the slot 210a in the space between the second engaging block 211 and the second fixing part 214. The plate-shaped second fixing part 214 facilitates fixing to the back cover 200 by dispensing adhesive, making it easier to fix the second buckle 210. If the second buckle 210 is directly injection molded, the second fixing part 214 is not required.

[0070] The following is combined Figure 2-4 , Figure 15-17 As shown, in one embodiment of this utility model, the electronic device 1 further includes a locking mechanism 600, which is used to pre-fix the back cover 200 during the installation process and to ensure that the electronic device 1 meets the drop strength requirements after the back cover 200 is installed.

[0071] In this embodiment, the engaging mechanism 600 includes a cooperating third latch 610 and a fourth latch 620. The third latch 610 protrudes from the rear cover 200, and the fourth latch 620 is located on the middle frame 400. When the rear cover 200 is pressed against the middle frame 400, the third latch 610 engages with the fourth latch 620, thereby achieving pre-fixation of the rear cover 200. When the rear cover 200 is removed, applying force to the rear cover 200 to move it away from the middle frame 400 allows the third latch 610 to disengage from the fourth latch 620, thus removing the rear cover 200. In this embodiment, to meet the stability requirements of the pre-fixed rear cover 200 and the overall drop strength requirements of the electronic device 1, multiple pairs of third latches 610 and fourth latches 620 are provided. The multiple third latches 610 are spaced apart along the edge of the rear cover 200. (See attached diagram) Figure 4 As shown, each of the fourth buckles 620 is located on the middle frame 400 at a position corresponding to the third buckle 610, as follows: Figure 2 As shown. The specific number of the third clip 610 and the fourth clip 620 is not limited.

[0072] In this embodiment, to meet the different material requirements of the back cover 200, such as sheet metal or alloy, the third buckle 610 is integrally formed with the back cover 200 or separately formed and then fixed to the back cover 200. In a preferred embodiment, the back cover 200 is made of composite sheet metal; therefore, the third buckle 610 adopts a separate design and is fixed to the back cover 200 by adhesive dispensing. When the back cover 200 is made of plastic, the third buckle 610 can be directly injection molded, that is, integrally formed with the back cover 200. In this case, the third buckle 610 can also be fixed or formed by other methods.

[0073] See Figure 15-16 As shown, in one embodiment, the third buckle 610 includes a third fixing part 615, a second connecting part 614 protruding from the third fixing part 615, and a third engaging block 611 protruding from the end of the second connecting part 614. The third fixing part 615 has a plate-like structure and is fixed to the side of the back cover 200 by adhesive application. The second connecting part 614 protrudes alternately from the surface of the back cover 200, and the third engaging block 611 protrudes and bends relative to the second connecting part 614. More preferably, the end of the third engaging block 611 is provided with a third inclined surface 612 and a first abutting surface 613. The third inclined surface 612 and the first abutting surface 613 are located on opposite sides, and the first abutting surface 613 is inclined. Specifically, both the first abutting surface 613 and the third inclined surface 612 are inclined and converge towards the end of the third engaging block 611.

[0074] Correspondingly, the fourth latch 620 has a fourth engaging block 621 protruding along the first direction (X direction), and the end of the fourth engaging block 621 is provided with a fourth inclined surface 622 that cooperates with the third inclined surface 612 and a second abutting surface 623 that cooperates with the first abutting surface 613. The third engaging block 611 is detachably engaged with the fourth engaging block 621. Specifically, during the movement of the rear cover 200 along the second direction (Z direction), the third inclined surface 612 of the third engaging block 611 first abuts against the fourth inclined surface 622 of the fourth latch 620. Through the movement of the third inclined surface 612 along the fourth inclined surface 622, it is easier for the third engaging block 611 to engage with the fourth engaging block 621. When the third engaging block 611 engages with the fourth engaging block 621, the first abutting surface 613 of the third engaging block 611 abuts against the second abutting surface 623 of the fourth engaging block 621, as shown. Figure 16As shown. The inclined surfaces of the first contact surface 613 and the second contact surface 623 make it easier for the first contact surface 613 of the third latching block 611 to move along the second contact surface 623 of the fourth latching block 621 during the process of removing the back cover 200, thereby making it easier for the third latch 610 to disengage from the fourth latch 620 and making it easier to remove the back cover 200.

[0075] See again Figure 2-4 As shown, in this embodiment, the middle frame 400 is further provided with a plurality of third mounting holes 430, the positions of which correspond to the positions of the third buckles 610 fixed on the rear cover 200. The fourth buckle 620 protrudes from the side wall of the middle frame 400 and corresponds to the third mounting holes 430. Therefore, when the rear cover 200 is assembled, the third buckles 610 fixed on it pass through the corresponding third mounting holes 430, and then the rear cover 200 is pressed inward, so that the third buckles 610 engage with the fourth buckles 620, as shown. Figure 16 As shown, this achieves pre-fixation of the rear cover 200, making the assembly of the rear cover 200 more convenient, while ensuring the fixation strength of the rear cover 200 after assembly to meet the strength requirements of the entire machine in case of a drop.

[0076] Recombined Figure 2-4 , Figure 15 , Figure 17 As shown, in one embodiment of this utility model, the electronic device 1 further includes a fixing mechanism 700 to further enhance the overall drop strength requirements of the electronic device 1. Specifically, the fixing mechanism 700 includes at least one connecting block 710, which protrudes from one side of the rear cover 200, such as... Figure 4 , Figure 17 As shown. In a preferred embodiment, to meet the different material requirements of the back cover 200, such as sheet metal or alloy, the connecting block 710 is integrally formed with the back cover 200 or separately formed and then fixed to the back cover 200. For example, when the back cover 200 is made of composite sheet metal, the connecting block 710 needs to be separately formed and then fixed to the back cover 200 by dispensing adhesive; when the back cover 200 is made of plastic, the connecting block 710 can be directly injection molded, that is, integrally formed with the back cover 200. After the back cover 200 is connected to the middle frame 400 through the aforementioned locking mechanism 600 and quick-release mechanism 110, the connecting block 710 is then fixed to the middle frame 400 and / or the back shell 300. This strengthens the assembly strength of the electronic device 1, reduces the risk of mechanism failure during drop, and meets the overall strength requirements for drop testing.

[0077] Combination Figure 4 , Figure 17As shown, one end of the connecting block 710 is provided with a fourth fixing part 712. The fourth fixing part 712 is plate-shaped or planar. The fourth fixing part 712 is fixed to the rear cover 200 by adhesive application, causing the connecting block 710 to protrude along the second direction (Z direction). At the same time, the connecting block 710 is provided with a connecting hole 711. A first fixing member 720 (such as a screw) is inserted into the middle frame 400 and / or the rear shell 300 and locked in the connecting hole 711, thereby realizing the fixation of the middle frame 400 and / or the rear shell 300 to the connecting block 710.

[0078] More preferably, a second fixing member 730 is built into the connecting hole 711 of the connecting block 710, and the second fixing member 730 is detachably connected to the first fixing member 720. The connecting block 710 is fixed to the middle frame 400 and / or the rear shell 300 by the detachable connection between the first fixing member 720 and the second fixing member 730. For example, the second fixing member 730 can be a metal nut, which is molded in-mold with the connecting block 710 to form an integral structure, and the first fixing member 720 can be a screw, but it is not limited thereto.

[0079] Combination Figure 2 , Figure 17 As shown, in one embodiment, the middle frame 400 is provided with a fourth mounting hole 440 corresponding to the connecting block 710. After the rear cover 200 is pre-fitted, the connecting block 710 is accommodated in the fourth mounting hole 440. A screw hole is provided on the frame 320 of the rear shell 300. A screw passes through the frame 320 and connects to the nut inside the connecting block 710, thereby fixing the connecting block 710 to the rear shell 300, further strengthening the assembly strength of the electronic device 1, ensuring the safety of the mechanism during a drop, and meeting the overall strength requirements for the device during a drop.

[0080] Let's combine them again below. Figures 1-17 As shown, the assembly principle of the electronic device 1 of this utility model and the disassembly and installation principle of the back cover 200 are explained.

[0081] First, the assembly sequence of electronic device 1 is as follows: First, fix the middle frame 400 and the back shell 300 with adhesive. After fixing, the middle frame 400 is housed inside the back shell 300, one side of the middle frame 400 is attached to the bottom plate 310 of the back shell 300, and the side wall of the middle frame 400 is attached to the frame 320 of the back shell 300. Figure 2 As shown. Simultaneously, the first latch 111 of the quick-release mechanism 110 protrudes through the first through hole 311 on the base plate 310, while the ejection mechanism 120 protrudes through the second through hole 311, as shown. Figure 2-3 As shown. Then, assemble the PCBA and other components. After that, assemble the LCM module 500, and finally assemble the back cover 200.

[0082] When assembling the back cover 200, the back cover 200 is placed on the middle frame 400, and the second buckle 210 on the back cover 200 corresponds to the first buckle 111. Simultaneously, the third buckle 610 corresponds to the third mounting hole 430 on the middle frame 400, and the connecting block 710 corresponds to the fourth mounting hole 440. Pressing the back cover 200 inward causes the second buckle 210 to push against the first buckle 111, causing the first buckle 111 to overcome the elastic force of the first elastic member 113 and move along the first direction (X direction). When the second buckle 210 moves to the slot 210a corresponding to the first buckle 111, the first engaging block 1111 engages with the slot 210a under the elastic force of the first elastic member 113. Figure 10 As shown. During the aforementioned compression of the back cover 200, the third latch 610 moves along the fourth latch 620, and ultimately engages with the fourth latch 620, as shown. Figure 16 As shown. Furthermore, the connecting block 710 is housed within the fourth mounting hole 440. This pre-fixes the rear cover 200, making assembly of the rear cover 200 easier.

[0083] Furthermore, after the back cover 200 is pre-fixed, it is connected to the nut inside the connecting block 710 by screws passing through the frame 320, as shown. Figure 17 As shown, the connecting block 710 is thus fixed to the rear shell 300, further strengthening the assembly strength of the electronic device 1, ensuring the risk of mechanism failure during the drop process, and meeting the overall strength requirements of the device during the drop.

[0084] Secondly, when disassembling the back cover 200, the screws connected to the connecting block 710 must first be removed to release the fixation between the back cover 200 and the back shell 300. Then, the user inserts a SIM card pin through the SIM card pin hole 1141 on the SIM card pin bracket 114 and presses the push surface 1121 of the SIM card pin spring 112. Under the action of force, the SIM card pin spring 112 moves inward along the first direction (X direction). The SIM card pin spring 112 drives the first latch 111 to move inward synchronously. During the movement of the first latch 111, it compresses the first elastic element 113 to keep it in a compressed state until the first latch 111 disengages from the slot 210a of the second latch 210. Figure 11 As shown. At this time, the quick-release mechanism 110 is in the unlocked state. In this application, the pin spring 112 can only be triggered by the pin passing through the pin hole 1141 with a smaller diameter to achieve unlocking. Moreover, during the triggering process, the first elastic element 113 is compressed and there is obvious tactile feedback. Compared with external buttons and other methods, this structural design has a better anti-accidental touch function, making the performance of the first latch 111 in engaging the back cover 200 stable. When the pin is removed, the first elastic element 113 rebounds, driving the first latch 111 back to the locked position.

[0085] When the quick-release mechanism 110 releases the rear cover 200, the pressure of the rear cover 200 against the ejector seat 121 disappears. At this time, the second elastic element 122 returns to its original deformation and drives the ejector seat 121 to reset, thereby ejecting the rear cover 200. Figure 14 As indicated by the arrow, the rear cover 200 is pushed up at one corner, causing that corner to lift. The user can then pry open the rear cover 200, disengaging the third clip 610 from the fourth clip 620, thus removing the rear cover 200. In this application, the rear cover 200 is automatically ejected by the ejection mechanism 120, allowing for quick removal without the need for a pry bar to damage the rear shell 300 or specialized equipment, achieving the requirement of non-destructive disassembly of the entire machine.

[0086] In summary, the quick-release anti-accidental contact device 100 of this utility model is provided with a quick-release mechanism 110 and an ejection mechanism 120. The quick-release mechanism 110 includes a first buckle 111, which is movably installed in the middle frame 400 along a first direction and can be separably engaged with the rear cover 200. The ejection mechanism 120 is installed in the middle frame 400 and can move along a second direction. When the rear cover 200 is engaged with the first buckle 111, it compresses the ejection mechanism 120 to generate a pre-pressure. When the first buckle 111 slides away from the rear cover 200, the pre-pressure of the ejection mechanism 120 pushes the rear cover 200 to eject the rear cover 200. First, the first latch 111 is hidden inside the middle frame 400 and can only be triggered by a locator pin. The concealed triggering mechanism prevents accidental activation and ensures stable locking of the back cover 200 by the first latch 111. Second, the back cover 200 is automatically ejected by the ejection mechanism 120, eliminating the need for specialized equipment to disassemble the back cover 200 or for a pry bar to damage the back shell 300. The back shell 300 can be opened without damage, thus meeting the requirement of non-destructive disassembly of the entire device. Finally, the electronic components can be recycled and replaced by removing the back cover 200, and it can be locked into the first latch 111 by squeezing the back cover 200. This provides a pre-fixation effect for assembling the back cover 200, making its assembly convenient and achieving non-destructive quick disassembly and installation of the entire device.

[0087] Correspondingly, the electronic device 1 having the quick-release anti-accidental-touch device 100 of the housing of this utility model also has the above-mentioned technical effects.

[0088] The structures of other parts of the electronic device 1 involved in this utility model are all conventional structures well known to those skilled in the art, and will not be described in detail here.

[0089] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
