Description

[0001] This application claims priority to the application No. 202420189506.0 filed with the China Patent Office on January 25, 2024, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure relates to the field of communication technology, in particular to an optical module. BACKGROUND

[0003] An optical module is composed of optoelectronic devices, functional circuits, optical interfaces, etc., and is an optoelectronic device for optical-electric and electric-optical conversion. Optical modules are classified according to packaging forms, mainly including SFP (Small Form-Factor Pluggable), GBIC (Gigabit Interface Converter), XFP (10Gigabit Small Form Factor Pluggable), etc. Among them, the SFP optical module is a hot-pluggable small package optical module of SFP split. Since the SFP optical module needs to be frequently plugged and unplugged from the host computer during use, in order to make the plugging and unplugging of the SFP optical module convenient, an unlocking part for facilitating plugging and unplugging from the host computer is provided on the SFP optical module. At present, the unlocking part of the SFP optical module is a pull ring that exerts force in the direction of pulling out the optical module, so that the linear movement distance of the pull ring and the optical module is relatively long, which is easy to interfere with other devices in some equipment. Therefore, for some equipment, the unlocking part of the SFP optical module is not applicable. CONTENT OF THE UTILITY MODEL

[0004] The present disclosure provides an optical module, which solves the technical problem that the unlocking part of the current SFP optical module is not applicable.

[0005] In some embodiments, an optical module is provided, comprising:

[0008] The first upper side plate is located on one side of the cover plate.

[0009] The second upper side plate is located on the other side of the cover plate.

[0010] The support plate is located on the opposite side of the cover plate.

[0011] The unlocking part comprises:

[0012] A pull ring is assembled to the first upper side plate, the second upper side plate and the supporting plate; the pull ring can rotate on the first upper side plate and the second upper side plate

[0094] Some embodiments of the present disclosure will be described in detail below with reference to the drawings. However, the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided in the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0095] Unless otherwise required by context, the term "comprises" is to be interpreted as open, inclusive language, i.e., "comprises, but is not limited to"; the terms "first", "second", etc., are to be interpreted as ordinal, not as indicating importance or quantity; the term "multiple" means two or more; the term "connected" is to be interpreted broadly, including as being either "directly connected" or "indirectly connected" through one or more intermediate components, whether or not the intermediate components are explicitly shown or described; the term "adapted to" or "configured to" is used interchangeably with "designed to" or "arranged to" and means that the device is adapted to perform the function or step, or is configured to perform the function or step; the terms "parallel", "perpendicular", "identical", "uniform", "flush", etc., are not limited to absolute mathematical relationships, but also include acceptable error ranges in practice, and also include differences based on the same design concept but caused by manufacturing reasons.

[0096] In optical communication technology, in order to establish information transmission between information processing devices, information needs to be loaded onto light, and the transmission of information is achieved by using the propagation of light. Here, the light loaded with information is an optical signal. The optical signal can reduce the loss of optical power during transmission in the information transmission device, so as to achieve high-speed, long-distance, low-cost information transmission. The signal that can be recognized and processed by the information processing device is an electrical signal. The information processing device usually includes an optical network unit (ONU), a gateway, a router, a switch, a mobile phone, a computer, a server, a tablet computer, a television, etc., and the information transmission device usually includes an optical fiber and an optical waveguide, etc.

[0097] The optical module can realize the mutual conversion between the optical signal and the electrical signal between the information processing device and the information transmission device. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected with an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected with an optical network unit; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected with the optical module, without the need for all the information processing devices to be directly connected with the optical module. Here, the information processing device directly connected with the optical module is referred to as the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be referred to as an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be referred to as an electrical port.

[0098] Figure 1 A partial structure diagram of an optical communication system according to some embodiments. As shown in Figure 1 , the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical module 200, an optical fiber 101, and a network cable 103.

[0099] One end of the optical fiber 101 extends to the direction of the remote information processing device 1000, and the other end of the optical fiber 101 is connected with the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal occurs multiple times of total reflection in the optical fiber 101, so as to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0100] The optical communication system can include one or more optical fibers 101, and the optical fiber 101 is detachably connected with the optical module 200, or fixedly connected. The host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0101] The host computer 100 includes a housing in the shape of a cuboid, and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to access the optical module 200, so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

[0102] The host computer 100 also includes an external electrical interface, which can access an electrical signal network. For example, the external electrical interface includes a universal serial bus (USB) or a network interface 104, which is configured to access a network cable 103, so that the host computer 100 and the network cable 103 establish a unidirectional or bidirectional electrical signal connection. One end of the network cable 103 is connected to a local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, a third electrical signal from the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, and the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101. The second optical signal is transmitted to a remote information processing device 1000 in the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that the optical module is a tool for converting optical signals and electrical signals, and the information does not change in the conversion process of the optical signals and the electrical signals, and the encoding and decoding mode of the information can change.

[0103] In addition to including an optical network terminal, the host computer 100 also includes an optical line terminal (OLT), an optical network terminal (ONT), or a data center server, etc.

[0104] Figure 2 A partial structural diagram of a host computer according to some embodiments. For clarity of display of the connection relationship between the optical module 200 and the host computer 100, Figure 2 Only the structure of the host computer 100 related to the optical module 200 is shown. As Figure 2 shown, the host computer 100 further includes a PCB circuit board 105 arranged in the shell, a cage 106 arranged on the surface of the PCB circuit board 105, a heat sink 107 arranged on the cage 106, and an electrical connector arranged inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins to increase the heat dissipation area.

[0105] The optical module 200 is inserted into the cage 106 of the host computer 100, and the optical module 200 is fixed by the cage 106. The heat generated by the optical module 200 is conducted to the cage 106, and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected with the electrical connector inside the cage 106, so that the optical module 200 and the host computer 100 establish a bidirectional electrical signal connection. In addition, the optical port of the optical module 200 is connected with the optical fiber 101, so that the optical module 200 and the optical fiber 101 establish a bidirectional optical signal connection.

[0106] Figure 3 A structural diagram of an optical module according to some embodiments, Figure 4 An exploded view of an optical module according to some embodiments. As Figure 3 and Figure 4 shown, the optical module 200 includes a shell, a circuit board 300 arranged in the shell, a light emitting component 400, and a light receiving component 500. However, the present disclosure is not limited thereto, and in some embodiments, the optical module 200 includes one of the light emitting component 400 and the light receiving component 500.

[0107] The shell includes an upper shell 201 and a lower shell 202, the upper shell 201 covers the lower shell 202 to form the above-mentioned shell having two openings 204 and 205; the outer contour of the shell generally presents a square body.

[0108] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates located on both sides of the bottom plate 2021 and arranged perpendicularly to the bottom plate 2021; the upper shell 201 includes a cover plate 2011, which covers the two lower side plates of the lower shell 202 to form the above-mentioned shell.

[0109] In some embodiments, the support plate 2016 can be located in the lower shell, which is not specifically limited here.

[0110] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates located on both sides of the base plate 2021 and arranged perpendicularly to the base plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The two upper side plates are combined with the two lower side plates to achieve the upper shell 201 covering the lower shell 202.

[0111] In some embodiments, the upper housing 201 includes a cover plate 2011, and a first upper side plate 20121 and a second upper side plate 20122 located on both sides of the cover plate 2011 and arranged perpendicular to the cover plate 2011. The first upper side plate 20121 and the second upper side plate 20122 extend from one end of the cover plate 2011 to the other end of the cover plate 2011.

[0112] The direction of the line connecting the two openings 204 and 205 may be consistent with the length direction of the optical module 200, or may be inconsistent with the length direction of the optical module 200. For example, the opening 204 is located at the end of the optical module 200 ( Figure 3 The opening 205 is also located at the end of the optical module 200 ( Figure 3 Alternatively, opening 204 is located at the end of optical module 200, while opening 205 is located on the side of optical module 200. Opening 205 is an electrical port, from which the circuit board's gold fingers extend and plug into the electrical connector of host computer 100. Opening 205 is an optical port, configured to receive an external optical fiber 101, thereby connecting optical fiber 101 to the optical emitting component 400 and the optical receiving component 500 in optical module 200.

[0113] In some examples, a support plate 2016 is provided at the optical port of the upper housing 201, and the support plate 2016 is located on the opposite side of the cover plate 2011. The support plate 2016 has a housing gap 2015 to facilitate marking the direction of the optical module and avoid errors when inserting external optical fibers into the optical port.

[0114] The combined assembly of the upper housing 201 and the lower housing 202 facilitates installation of the circuit board, light emitting component 400, light receiving component 500, and the like within the housing, which then encapsulates and protects these components. Furthermore, during assembly of the circuit board, light emitting component 400, and light receiving component 500, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are easily positioned, facilitating automated production.

[0115] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0116] In some embodiments, the light module 200 further comprises an unlocking component 600 outside the housing thereof. The unlocking component 600 is configured to achieve the fixed connection between the light module 200 and the host machine, or to release the fixed connection between the light module 200 and the host machine.

[0117] Figure 5A A partial view of an unlocking component according to some embodiments in connection with an upper housing, Figure 5B A partial exploded view of an unlocking component according to some embodiments in connection with an upper housing. As Figure 5A and Figure 5B As shown in FIGS. 1 and 2, in some embodiments, the surface of the cover plate 2011 of the upper housing 201 is provided with a matching protrusion 2013, which is used to be buckled with the corresponding component on the cage 106. When the light module 200 is inserted into the cage 106, the matching protrusion 2013 fixes the light module 200 in the cage 106.

[0118] In some embodiments, the unlocking component 600 can comprise a pull ring 610 and an unlocking piece 620, which can be assembled to the housing. The pull ring 610 can be rotated on the housing, and when the pull ring 610 is rotated, the unlocking piece 620 can be pushed. When the unlocking piece 620 is pushed, the unlocking piece 620 can change the connection relationship between the matching protrusion 2013 and the cage 106, so as to release the fixed relationship between the light module 200 and the cage 106, and thus the light module 200 can be pulled out of the cage 106. Exemplarily, the pull ring 610 can be assembled to the upper housing 201, and the unlocking piece 620 can be assembled to the upper housing 201. Of course, in some embodiments, the pull ring 610 or the unlocking piece 620 can be assembled to the lower housing 202.

[0119] In some embodiments, the upper housing 201 is formed with a clamping shaft 210. The clamping shaft 210 is assembled to the pull ring 610, so that the pull ring 610 can be rotated on the upper housing 201. Exemplarily, the outer side of one end of the first upper side plate 20121 and the outer side of one end of the second upper side plate 20122 are both formed with the clamping shaft 210, and the pull ring 610 is formed with shaft holes on both sides thereof. The shaft holes on both sides of the pull ring 610 are respectively assembled to the clamping shaft 210 on the first upper side plate 20121 and the second upper side plate 20122. When the pull ring 610 is pulled, the pull ring 610 can be rotated around the clamping shaft 210.

[0120] In some embodiments, the upper shell 201 is formed with a mounting seat 220 on one side of the matching protrusion 2013 close to the light port. The mounting seat 220 is fitted with a unlocking member 620, which is movable relative to the mounting seat 220. The pull ring 610 is rotatable to push the unlocking member 620 to move on the mounting seat 220. The unlocking member 620 is fitted with the mounting seat 220 and has a locking position and an unlocking position during the movement relative to the mounting seat. When the unlocking member 620 is at the locking position, the matching protrusion 2013 is buckled with the cooperating buckle on the cage 106, and the light module 200 is fixed with the cage 106, and the whole light module 200 cannot be taken out of the cage. When the unlocking member moves to the unlocking position, the unlocking member 620 can drive the end of the cooperating buckle to lift up, so that the cooperating buckle moves along the surface of the matching protrusion and is separated from the matching protrusion 2013, so as to release the buckling relationship between the matching protrusion 2013 and the cage 106, so that the light module 200 can be separated from the cage 106, and the light module 200 can be taken out of the cage.

[0121] In some embodiments, the unlocking member 600 can include a resilient member 630. The resilient member 630 is fitted with the unlocking member 620 and the mounting seat 220. When the pull ring 610 pushes the unlocking member 620 to move to the unlocking position, the resilient member 630 is compressed to produce deformation. When the force of rotating the pull ring 610 becomes small, the resilient member 630 returns to the original shape to produce a force to push the unlocking member 620 to move to the locking position. For example, the resilient member 630 can be a spring or other resilient member capable of producing recoverable deformation.

[0122] In some embodiments, the unlocking member 600 can include a first resilient member 631 and a second resilient member 632. The first resilient member 631 is located on one side of the unlocking member 620, and the second resilient member 632 is located on the other side of the unlocking member 620.

[0123] In some embodiments, in order to better embed the matching protrusion 2013 in the cooperating buckle, the surface of the cover plate 2011 is provided with a buckle groove 2014. The surface of the buckle groove 2014 is recessed downward to the lower shell relative to the surface of the cover plate 2011, and the matching protrusion 2013 is located in the buckle groove 2014, so that the bottom of the buckle groove 2014 is lower than the surface of the cover plate 2011.

[0124] The profile area of the cooperating buckle is smaller than the bottom area of the buckle groove 2014, and when the unlocking member is at the locking position, the cooperating buckle is completely located in the buckle groove 2014.

[0125] In some embodiments, the matching protrusions 2013 are triangular protrusion structures, which can be connected with the annular mating buckle on the cage to fix the position of the optical module relative to the cage, so as to ensure that the optical module can work stably. From left to right, the protrusion height of the matching protrusions 2013 gradually decreases, so as to reduce the friction between the mating buckle and the matching protrusions during the movement of the mating buckle from right to left, and avoid the steps caused by different heights so that the mating buckle abuts against the steps.

[0126] In some embodiments, from left to right, the triangular protrusions present an inverted triangular shape, that is, one corner of the triangular protrusion points to the direction of the electrical port, and the shape of the mating buckle matches the shape of the triangular protrusion. The corner of the triangular protrusion presents a circular arc chamfer, so that the connection between the triangular protrusion and the mating buckle is smoother, and the friction between the mating buckle and the matching protrusion is reduced.

[0127] Figure 6A FIG. 6 is a schematic diagram of a pull ring according to some embodiments, Figure 6B FIG. 7 is a structural diagram of a pull ring according to some embodiments, Figure 6A and Figure 6B The pull ring can be shown from different angles. As shown in Figure 6A and Figure 6B In some embodiments, the pull ring 610 includes a pull ring body 611 and a pull ring sleeve 612. The pull ring body 611 can be a sealed or semi-sealed annular structure. The pull ring sleeve 612 is sleeved on one side of the pull ring body 611, and the pull ring sleeve 612 can facilitate the fixation of the pull ring body 611 and the shell. The pull ring sleeve 612 can be provided with an identification mark to distinguish the type of the optical module. For example, the identification mark provided on the pull ring sleeve 612 can be distinguished by color or letter.

[0128] In some embodiments, the pull ring body 611 includes a first arm 6111, a second arm 6112, a third arm 6113, and a fourth arm 6114 connected in sequence, and a bending portion 6115 located at the first arm 6111. For example, the side edge at the top of the second arm 6112 is connected to one end of the first arm 6111, and the side edge at the top of the fourth arm 6114 is connected to the other end of the first arm 6111, so that the first arm 6111 is suspended outside the second arm 6112 and the fourth arm 6114.

[0129] In order to reduce the size of the occupied space of the optical module while enhancing the strength of the pull ring body 611, the width of each arm of the pull ring body 611 is greater than its thickness.

[0130] In some embodiments, the first arm 6111 is arranged opposite to the third arm 6113, and the second arm 6112 is arranged opposite to the fourth arm 6114. When the unlocking member 620 is in the unlocking position, in order to reduce the occupied space of the optical module, the second arm 6112 is located outside the first upper side plate 20121, the fourth arm 6114 is located outside the second upper side plate 20122, the first arm 6111 is located at one end of the cover plate 2011, and the width of the first arm 6111 is distributed along the up-down direction of the optical module. The third arm 6113 is located on the outer wall of the supporting plate 2016.

[0131] In some embodiments, the first arm 6111 is arranged perpendicular to the third arm 6113, and the third arm 6113 is located on the outer wall of the supporting plate 2016, thereby reducing the occupied space of the optical module in the left-right direction.

[0132] In some embodiments, the bending part 6115 is located on the side wall of the first arm 6111, and the bending part 6115 is located between the second arm 6112 and the fourth arm 6114. The second arm 6112 and the fourth arm 6114 can protect the bending part 6115.

[0133] In some embodiments, the lower surface of the bending part 6115 is higher than the lower surface of the first arm 6111, so that the bending part 6115 is located above the cover plate. For example, there is a gap between the lower surface of the bending part 6115 and the upper surface of the cover plate 2011.

[0134] In some embodiments, the top of the second arm 6112 is formed with a first shaft hole 6117, and the top of the fourth arm 6114 is formed with a second shaft hole 6118. For example, the center lines of the first shaft hole 6117 and the second shaft hole 6118 are flush with the surface of the cover plate 2011, so that the pull ring 610 remains balanced during rotation and reduces the friction between the pull ring 610 and the surface of the upper shell 201.

[0135] In some embodiments, the bending part 6115 can include a bending component 61151 and a reinforcing component 61152, wherein the bending component 61151 is located between the first arm 6111 and the reinforcing component 61152, and the bending component 61151 has a circular arc shape. When the unlocking member 620 is in the locking position, the reinforcing component 61152 is located above one end of the cover plate 2011, the left end of the unlocking member 620 contacts the reinforcing component 61152, and the reinforcing component 61152 is perpendicular to the cover plate 2011. The first arm 6111 is located on the left side of the reinforcing component 61152. The reinforcing component 61152 can be parallel to the first arm 6111.

[0136] In some embodiments, both the first arm 6111 and the reinforcement component 61152 are plate-like structures, and a gap may be provided between the first arm 6111 and the reinforcement component 61152. To increase the strength of the pull ring and prevent deformation during unlocking, the gap between the first arm 6111 and the reinforcement component 61152 may be filled with reinforcing material.

[0137] During unlocking, the third arm 6113 is pulled upward and to the left, causing the first arm 6111 and the bent portion 6115 to move downward and to the right around the axis of rotation. The contact point between the pull ring 610 and the unlocking member 620 gradually shifts from the reinforcing member 61152 to the curved member 61151, pushing the unlocking member 620 to the right. The curved member 61151 makes the unlocking process smoother and reduces jamming.

[0138] When the unlocking member 620 is in the unlocking position, the reinforcing member 61152 is arranged parallel to the cover plate 2011, and the first arm 6111 is located above the reinforcing member 61152. In some embodiments, the third arm 6113 can be a whole plate material or formed by two plate materials, such as Figure 6A The third arm 6113 shown in FIG is formed by two plate-like materials and has an arm gap 6116 . The pull ring assembly 612 is sleeved on the surface of the third arm 6113 , and the pull ring assembly 612 covers the arm gap 6116 .

[0139] In some embodiments, the width of the arm gap 6116 is smaller than the width of the housing gap 2015 , the pull ring assembly 612 covers the arm gap 6116 , and the pull ring assembly 612 covers the housing gap 2015 .

[0140] In some embodiments, a first chamfer 615 is provided at the upper right corner of the second arm 6112. The first chamfer is arc-shaped, so that when the pull ring is pulled to the upper left, the sliding between the second arm 6112 and the cover plate is smoother, reducing jamming.

[0141] In some embodiments, a second chamfer 616 is provided at the upper right corner of the fourth arm 6114, and the third chamfer is arc-shaped, so that when the pull ring is pulled to the upper left, the sliding between the fourth arm 6114 and the cover plate is smoother, reducing jamming.

[0142] Figure 7A Another pull ring structure according to some embodiments is Figure 1 , Figure 7B Another pull ring structure according to some embodiments is Figure 2 .like Figure 7A and Figure 7BAs shown, in some embodiments, the pull ring 610 may include a first connecting portion 613 and a second connecting portion 614. The bottom of the first connecting portion 613 is connected to the top of the second support arm 6112, and the top side of the first connecting portion 613 is connected to one end of the first support arm 6111. The bottom of the second connecting portion 614 is connected to the top of the fourth support arm 6114, and the top side of the second connecting portion 614 is connected to the other end of the first support arm 6111.

[0143] In some embodiments, a first driving surface 6131 is formed on the other side of the first connecting portion 613. The bottom of the first driving surface 6131 contacts one end of the driving member 620. For example, the first driving surface 6131 is an arcuate surface. When the pull ring 610 rotates, the first driving surface 6131 rotates, pushing the unlocking member 620. As the first driving surface 6131 rotates, the contact position between the first driving surface 6131 and the unlocking member 620 continuously changes. When the unlocking member 620 is in the unlocked position, the top of the first driving surface 6131 contacts one end of the driving member 620.

[0144] In some embodiments, a second driving surface 6141 is formed on the other side of the second connecting portion 614. The bottom of the second driving surface 6141 contacts one end of the driving member 620. Exemplarily, the second driving surface 6141 is an arcuate surface. When the pull ring 610 rotates, the second driving surface 6141 rotates, pushing the unlocking member 620. As the second driving surface 6141 rotates, the contact position between the second driving surface 6141 and the unlocking member 620 continuously changes. When the unlocking member 620 is in the unlocked position, the top of the second driving surface 6141 contacts one end of the unlocking member 620.

[0145] Figure 8A A structure of an unlocking member according to some embodiments Figure 1 , Figure 8B An unlocking component structure according to some embodiments Figure 2 .like Figure 8A and Figure 8B As shown, in some embodiments, the unlocking member 620 may include an unlocking body 621. The first end of the unlocking body 621 is in contact with the pull ring, and the second end of the unlocking body 621 is located in the buckle groove 2014. When the unlocking member is in the locked position, the second end of the unlocking body 621 is located to the left of the mating buckle. During the unlocking process, the pull ring is pulled toward the upper left, and the first arm 6111 and the bent portion 6115 move toward the lower right around the rotation axis. The contact point between the pull ring 610 and the first end of the unlocking member 620 gradually moves from the reinforcing component 61152 to the curved component 61151, pushing the second end of the unlocking member 620 under the mating buckle, thereby raising the mating buckle and disengaging the mating buckle from the mating protrusion.

[0146] In some embodiments, the unlocking member 620 can include an unlocking guide 622 located at the side of the unlocking body 621. The unlocking guide 622 is assembled with the mounting seat 220 so that the unlocking body 621 can move on the upper shell 201.

[0147] In some embodiments, the unlocking member 620 can include an elastic member compression portion (also referred to as a spring compression portion in some technologies) 623 located at the side of the unlocking body 621. The elastic member compression portion 623 is assembled with the mounting seat 220 and the elastic member 630 so as to facilitate the elastic member 630 acting on the unlocking body 621.

[0148] In some embodiments, the second end of the unlocking body 621 is formed with a first elastic sheet guide 6211 and a second elastic sheet guide 6212, and a clearance groove 6213 is formed in the middle of the first elastic sheet guide 6211 and the second elastic sheet guide 6212. When the unlocking member 620 moves to the unlocking position, the matching protrusion 2013 can be located in the clearance groove 6213, the first elastic sheet guide 6211 is located on one side of the matching protrusion 2013, and the second elastic sheet guide 6212 is located on the other side of the matching protrusion 2013.

[0149] In some embodiments, the end of the first elastic sheet guide 6211 is formed with an inclined first guide slope 62111, and the inclined direction of the first guide slope 62111 is toward the right side. The first guide slope 62111 makes the thickness of the first elastic sheet guide 6211 gradually increase from right to left. The thickness of the right side of the first elastic sheet guide 6211 is small, which facilitates the insertion of the cooperating buckle into the gap formed by the upper cover plate 3011 during the unlocking process. The thickness of the left side of the first elastic sheet guide 6211 is greater than the maximum thickness of the matching protrusion 2013.

[0150] In some embodiments, the rightmost end of the first elastic sheet guide 6211 is provided with an enhanced cross section, which is located at the right end of the first guide slope 62111 and is perpendicular to the surface of the cover plate 2011, so that the thickness of the rightmost end of the first elastic sheet guide 6211 is increased. When the first elastic sheet guide 6211 initially contacts the cooperating buckle during the unlocking process, the thickness of the first elastic sheet guide 6211 gradually increases, which avoids the bending of the first elastic sheet guide 6211.

[0151] In some embodiments, the end of the second spring guiding portion 6212 is formed with a second guiding inclined surface 62121 which is inclined towards the right. The second guiding inclined surface 62121 makes the thickness of the second spring guiding portion 6212 gradually increase from right to left. The right side of the second spring guiding portion 6212 has a small thickness, which facilitates the insertion of the matching buckle into the gap formed by the upper cover plate 3011 during the unlocking process. The left side of the second spring guiding portion 6212 has a thickness greater than the maximum thickness of the matching protrusion 2013.

[0152] In some embodiments, in order to facilitate unlocking and avoid the matching buckle from tilting during the lifting process, the first spring guiding portion 6211 and the second spring guiding portion 6212 have the same inclined surface.

[0153] In some embodiments, the rightmost end of the second spring guiding portion 6212 is provided with a reinforced section which is located at the right end of the second guiding inclined surface 62121. The reinforced section is perpendicular to the surface of the cover plate 2011, so as to increase the thickness of the rightmost end of the second spring guiding portion 6212. This increases the thickness of the second spring guiding portion 6212 when it first contacts the matching buckle during the unlocking process, thereby avoiding the second spring guiding portion 6212 from being bent or broken.

[0154] The width of the avoiding groove 6213 is greater than the side length of the matching protrusion 2013, so that the matching protrusion 2013 is embedded between the first spring guiding portion 6211 and the second spring guiding portion 6212 in the unlocked position, so that both ends of the matching buckle are lifted, facilitating unlocking. The width of the avoiding groove 6213 is the distance between the first spring guiding portion 6211 and the second spring guiding portion 6212.

[0155] In some embodiments, one side of the unlocking body 621 is formed with a first unlocking guiding portion 6221 which protrudes outward relative to the side wall of the unlocking body 621. The side edge of the first unlocking guiding portion 6221 is connected to the side wall of the unlocking body 621. For example, the length of the first unlocking guiding portion 6221 is less than the length of the unlocking body 621, and the upper surface of the first unlocking guiding portion 6221 is lower than the upper surface of the unlocking body 621. The first unlocking guiding portion 6221 is fitted into the mounting seat 220, and can slide in the mounting seat 220.

[0156] In some embodiments, one end of the first unlocking guiding portion 6221 can be uneven with one end of the unlocking body 621. Of course, in some embodiments, one end of the first unlocking guiding portion 6221 can be flush with one end of the unlocking body 621.

[0157] In some embodiments, the first elastic member compression portion 6231 is located outside the first unlocking guide portion 6221. The first elastic member compression portion 6231 protrudes outward relative to the side wall of the first unlocking guide portion 6221. Illustratively, the length of the first elastic member compression portion 6231 is less than the length of the first unlocking guide portion 6221, and the first elastic member compression portion 6231 can be assembled and connected to the mounting seat 220 and the elastic member 630.

[0158] In some embodiments, the left end of the first elastic member compression portion 6231 is flush with the left end of the first unlocking guide portion 6221. Illustratively, to ensure that both sides of the unlocking body 621 are balanced during the unlocking process, the other side of the unlocking body 621 is also provided with a second unlocking guide portion 6222 and a second elastic member compression portion 6232.

[0159] In some embodiments, the other side of the unlocking body 621 is formed with a second unlocking guide portion 6222, which protrudes outward relative to the side wall of the unlocking body 621, and the side edge of the second unlocking guide portion 6222 is connected to the side wall of the other side of the unlocking body 621. Illustratively, the length of the second unlocking guide portion 6222 is less than the length of the unlocking body 621, and the upper surface of the second unlocking guide portion 6222 is lower than the upper surface of the unlocking body 621. The second unlocking guide portion 6222 is assembled to the mounting seat 220, and the second unlocking guide portion 6222 can slide in the mounting seat 220.

[0160] In some embodiments, one end of the second unlocking guide portion 6222 can be flush with one end of the unlocking body 621. Of course, in some embodiments, one end of the second unlocking guide portion 6222 can be flush with one end of the unlocking body 621.

[0161] In some embodiments, the second elastic member compression portion 6232 is located outside the second unlocking guide portion 6222. The second elastic member compression portion 6232 protrudes outward relative to the side wall of the second unlocking guide portion 6222. Illustratively, the length of the second elastic member compression portion 6232 is less than the length of the second unlocking guide portion 6222, and the second elastic member compression portion 6232 can be assembled and connected to the mounting seat 220 and the elastic member 630.

[0162] In some embodiments, the first unlocking guide portion 6221 can be symmetrically arranged with the second unlocking guide portion 6222, and the second elastic member compression portion 6232 can be symmetrically arranged with the first elastic member compression portion 6231.

[0163] In some embodiments, the top surface of the unlocking body 621 is provided with a first step 6214, which divides the top surface of the unlocking body 621 into two sub-bodies 6216 and 6215 of different heights. To prevent the unlocking component 600 from interfering with external structures, the right end of the first step 6214 does not extend beyond the left edge of the locking groove 2014 when in the locked position.

[0164] The first sub-body 6216 is located on the left side of the first step 6214 , the second sub-body 6215 is located on the right side of the first step 6214 , and the upper surface of the first sub-body 6216 is higher than the upper surface of the second sub-body 6215 .

[0165] The first end of the first sub-body 6216 abuts against the pull ring 610. The first end of the first step 6214 is connected to the second end of the first sub-body 6216. The second sub-body 6215 is connected to the second end of the first step 6214. The first end of the first step 6214 is higher than the second end of the first step 6214. The distance between the upper surface of the second sub-body 6215 and the upper surface of the cover plate 2011 is smaller than the distance between the upper surface of the first sub-body 6216 and the upper surface of the cover plate 2011.

[0166] Figure 8C A structure of an unlocking member according to some embodiments Figure 3 .like Figure 8C As shown, in some embodiments, the lower surface of the first spring sheet guide portion 6211 protrudes to form a first limiting protrusion 6226, so that the lower surface of the first spring sheet guide portion 6211 contacts the surface of the snap groove 2014, preventing the snap groove 2014 from causing the first spring sheet guide portion 6211 to be suspended in the air, thereby increasing the strength of the unlocking component 600.

[0167] In some embodiments, the lower surface of the first spring clip guide portion 6211 can be raised to form a first limiting protrusion 6226. The first limiting protrusion 6226 reduces the distance between the lower surface of the first spring clip guide portion 6211 and the upper surface of the snap groove 2014, so that the lower surface of the first spring clip guide portion 62112 contacts the surface of the snap groove 2014, so that the distance between the contact position between the mating buckle 1061 and the first spring clip guide portion 6211 and the upper surface of the snap groove 2014 is reduced as much as possible, thereby facilitating the sliding of the mating buckle 1061 in the first spring clip guide portion 6211.

[0168] In some embodiments, the upper surface of the second sub-body 6215 is lower than the upper surface of the first sub-body 6216, reducing the lifting height of the first spring guide portion 6211, facilitating the sliding of the mating buckle 1061 along the first spring guide portion 6211 to the upper surface of the second sub-body 6215, thereby achieving the separation of the mating buckle 1061 and the matching protrusion 2013.

[0169] The buckle groove 2014 limits the first limiting protrusion 6226 in the left-right direction, and the buckle groove 2014 enables the first elastic sheet guide portion 6211 to move in the buckle groove 2014, thereby preventing the unlocking member from moving to the left beyond the range when returning to the original position.

[0170] The lower surface protrusion of the second elastic sheet guide portion 6212 forms a second limiting protrusion 6227, so that the lower surface of the second elastic sheet guide portion 6212 is in contact with the surface of the buckle groove 2014, thereby preventing the buckle groove 2014 from suspending the second elastic sheet guide portion 6212 and increasing the strength of the unlocking component 600.

[0171] In some embodiments, the lower surface protrusion of the second elastic sheet guide portion 6212 forms a second limiting protrusion 6227, which reduces the distance between the lower surface of the second elastic sheet guide portion 6212 and the upper surface of the buckle groove 2014, so that the lower surface of the second elastic sheet guide portion 6212 is in contact with the surface of the buckle groove 2014, and the distance between the contact position of the matching buckle 1061 and the second elastic sheet guide portion 6212 and the upper surface of the buckle groove 2014 is reduced as much as possible, thereby facilitating the sliding of the matching buckle 1061 along the second elastic sheet guide portion 6212 to the upper surface of the second sub-body 6215 to achieve the separation of the matching buckle 1061 and the matching protrusion 2013.

[0172] In some embodiments, the upper surface of the second sub-body 6215 is lower than the upper surface of the first sub-body 6216, which reduces the lifting height of the second elastic sheet guide portion 6212, facilitates the sliding of the matching buckle 1061 along the second elastic sheet guide portion 6212 to the upper surface of the second sub-body 6215, and achieves the separation of the matching buckle 1061 and the matching protrusion 2013. The buckle groove 2014 limits the second limiting protrusion 6227 in the left-right direction, and the buckle groove 2014 enables the second elastic sheet guide portion 6212 to move in the buckle groove 2014, thereby preventing the unlocking member from moving to the left beyond the range when returning to the original position.

[0173] Figure 9A Structure of yet another unlocking member according to some embodiments Figure 1 , Figure 9B Structure of yet another unlocking member according to some embodiments Figure 2 . As shown in FIGS. Figure 9A and Figure 9B In some embodiments, one end of the unlocking body 621 is formed with a contact portion 624 for contacting the pull ring body 611, so that the pull ring body 611 can push the unlocking body 621 through the contact portion 624 when rotating. Exemplarily, the top of the contact portion 624 can be flush with the top of the one end of the unlocking body 621, and of course in some embodiments, the top of the contact portion 624 can be higher or lower than the top of the one end of the unlocking body 621.

[0174] In some embodiments, the width of the contact portion 624 is greater than the width of one end of the unlocking body 621, so as to increase the contact area between the pull ring body 611 and the unlocking member 620, thereby facilitating the pushing of the contact portion 624 by the pull ring body 611. For example, one side of the contact portion 624 protrudes from the side of the first unlocking guide portion 6221, and the other side of the contact portion 624 protrudes from the side of the second unlocking guide portion 6222.

[0175] In some embodiments, one side of the contact portion 624 is flush with the side of the first elastic member compression portion 6231, and the other side of the contact portion 624 is flush with the side of the second elastic member compression portion 6232.

[0176] In some embodiments, the top of one end of the first unlocking guide portion 6221 is formed with a first connecting block 6223, and the first connecting block 6223 connects the unlocking body 621 and the first unlocking guide portion 6221. The top of the first connecting block 6223 can be flush with the top of the unlocking body 621. The first connecting block 6223 can reinforce the connection between the first unlocking guide portion 6221 and the unlocking body 621 and the contact portion 624. For example, the first connecting block 6223 is formed with a first connecting surface 62231, which extends obliquely from the side of the contact portion 624 to the side of the unlocking body 621, and the angle between the first connecting surface 62231 and the side of the unlocking body 621 is obtuse, and the angle between the first connecting surface 62231 and the side of the contact portion 624 is obtuse. When the unlocking member 620 moves to the unlocking position, the first connecting surface 62231 can limit the connection with the side of the mounting seat 220.

[0177] In some embodiments, the top of one end of the second unlocking guide portion 6222 is formed with a second connecting block 6224, and the second connecting block 6224 connects the unlocking body 621 and the second unlocking guide portion 6222. The top of the second connecting block 6224 can be flush with the top of the unlocking body 621. The second connecting block 6224 can reinforce the connection between the second unlocking guide portion 6222 and the unlocking body 621 and the contact portion 624. For example, the second connecting block 6224 is formed with a second connecting surface 62241, which extends obliquely from the side of the contact portion 624 to the side of the unlocking body 621, and the angle between the second connecting surface 62241 and the side of the unlocking body 621 is obtuse, and the angle between the second connecting surface 62241 and the side of the contact portion 624 is obtuse. When the unlocking member 620 moves to the unlocking position, the second connecting surface 62241 can limit the connection with the side of the mounting seat 220.

[0178] Figure 10A Structure of another unlocking member according to some embodiments Figure 1 , Figure 10B Structure of another unlocking member according to some embodiments Figure 2 . For example Figure 10A andFigure 10B As shown, in some embodiments, one side of the contact portion 624 protrudes from a side of the first elastic member compression portion 6231 , and the other side of the contact portion 624 protrudes from a side of the second elastic member compression portion 6232 .

[0179] In some embodiments, a first assembly protrusion 6241 and a second assembly protrusion 6242 are formed on the bottom of the contact portion 624. The first assembly protrusion 6241 and the second assembly protrusion 6242 are formed by protruding outward from the bottom surface of the contact portion 624. The first assembly protrusion 6241 is located on one side of the contact portion 624, and the second assembly protrusion 6242 is located on the other side of the contact portion 624. The first assembly protrusion 6241 and the second assembly protrusion 6242 are assembled and connected to the upper housing 201.

[0180] Figure 11A A portion of an upper shell according to some embodiments Figure 1 , Figure 11B A portion of an upper shell according to some embodiments Figure 2 , Figure 11C A cross section of an upper housing according to some embodiments Figure 1 , Figure 11D A cross section of an upper housing according to some embodiments Figure 2 .like Figures 11A-11D As shown, in some embodiments, a first clamping shaft 211 is provided on the first upper side plate 20121, and a second clamping shaft 212 is provided on the second upper side plate 20122. The first clamping shaft 211 can be inserted into the first shaft hole 6117, and the second clamping shaft 212 can be inserted into the second shaft hole 6118. When the pull ring is pulled, the first shaft hole 6117 rotates on the first clamping shaft 211, and the second shaft hole 6118 rotates on the second clamping shaft 212, so that the pull ring 610 rotates on the upper housing 201.

[0181] In some embodiments, a mounting seat 220 is provided on the cover plate 2011 , and the mounting seat 220 can be movably connected to the unlocking member 620 . For example, the side of the unlocking member 620 can be assembled and connected to the mounting seat 220 .

[0182] In some embodiments, the mounting base 220 includes a first fixing portion 221 and a second fixing portion 222 disposed opposite each other, with a movable slot 223 formed therebetween. The unlocking member 620 is movably positioned within the movable slot 223 via an elastic member 630 and can extend out of the movable slot 223 to engage with the mating buckle under the drive of the first arm 6111. The movable slot 223 constrains the movement path of the unlocking member 620, allowing the elastic member to move only in a direction away from or toward the mating buckle (i.e., left-right). Exemplarily, an unlocking body 621 is positioned within the movable slot 223, with the first fixing portion 221 and the second fixing portion 222 limiting the unlocking body 621 on opposing sides.

[0183] In some embodiments, the first fixed part 221 is formed with a first avoiding slot 2211 and a second avoiding slot 2212, which are communicated. The first avoiding slot 2211 is recessed relative to the second avoiding slot 2212.

[0184] In some embodiments, the first avoiding slot 2211 is fitted with a first elastic piece compression part 6231. The length of the first avoiding slot 2211 can be greater than that of the first elastic piece compression part 6231, and the first elastic piece 631 is located at the left side of the first elastic piece compression part 6231. One end of the first elastic piece 631 is in contact with the side wall of the first elastic piece compression part 6231, and the other end of the first elastic piece 631 is in contact with the end of the second avoiding slot 2212. During the unlocking process, the first supporting arm 6111 rotates and pushes the first elastic piece compression part 6231 to slide from left to right in the first avoiding slot 2211, and the first elastic piece 631 is deformed under force. After the external force is removed, the first elastic piece 631 returns to its original position, driving the unlocking body 621 to return to its original position.

[0185] In some embodiments, the edge of the first elastic piece compression part 6231 can be rectangular or square, or other shapes. In order to reduce the friction between the elastic piece compression part and the first avoiding slot 2211, the edge of the elastic piece compression part is arc-shaped, and the corresponding first avoiding slot 2211 is arc-shaped.

[0186] In some embodiments, the second avoiding slot 2221 is fitted with a first unlocking guide part 6221. The length of the second avoiding slot 2221 can be greater than that of the first unlocking guide part 6221, and during the unlocking process, the first unlocking guide part 6221 slides in the second avoiding slot 2221. The right side wall of the second avoiding slot 2221 forms a right limit for the first unlocking guide part 6221, reducing the risk of the first unlocking guide part 6221 sliding to the right beyond the preset position.

[0187] In some embodiments, the second fixed part 222 is formed with a third avoiding slot 2221 and a fourth avoiding slot 2222, which are communicated. The third avoiding slot 2221 is recessed relative to the fourth avoiding slot 2222. Exemplarily, the third avoiding slot 2221 can be symmetrical to the first avoiding slot 2211, and the fourth avoiding slot 2222 can be symmetrical to the second avoiding slot 2212, facilitating the force balance of the unlocking body 621.

[0188] In some embodiments, the third avoiding groove 2221 is configured to connect the second elastic piece compression part 6232. The length of the third avoiding groove 2221 can be greater than the length of the second elastic piece compression part 6232, and the second elastic piece 632 is located on the left side of the second elastic piece compression part 6232. One end of the second elastic piece 632 is in contact with the side wall of the second elastic piece compression part 6232, and the other end of the second elastic piece 632 is in contact with the end of the fourth avoiding groove 2222. During the unlocking process, the first supporting arm 6111 rotates and pushes the second elastic piece compression part 6232 to slide from left to right in the third avoiding groove 2221, and the second elastic piece 632 is compressed under stress. After the external force is removed, the second elastic piece 632 returns to its original shape to drive the unlocking body 621 back to its original position.

[0189] In some embodiments, the fourth avoiding groove 2222 is configured to connect the second unlocking guide part 6222. The length of the fourth avoiding groove 2222 can be greater than the second unlocking guide part 6222, and the second unlocking guide part 6222 slides in the fourth avoiding groove 2222 during the unlocking process. The right side wall of the fourth avoiding groove 2222 limits the right side of the second unlocking guide part 6222, reducing the risk of the second unlocking guide part 6222 sliding to the right beyond the preset position.

[0190] In some embodiments, the surface of the cover plate 2011 is provided with a second recessed area 230, and the upper surface of the second recessed area 230 is recessed relative to the lower surface of the movable groove 223. The second recessed area 230 can avoid the bending part 6115.

[0191] In some embodiments, one end of the first fixed part 221 is provided with a first supporting arm avoiding part 2311, and one end of the second fixed part 222 is provided with a second supporting arm avoiding part 2321. The first supporting arm avoiding part 2311 and the second supporting arm avoiding part 2321 facilitate the avoidance of the first supporting arm 6111. When the unlocking component 600 is in the unlocking position, one end of the first supporting arm 6111 is located above the first supporting arm avoiding part 2311, and the other end of the first supporting arm 6111 is located above the second supporting arm avoiding part 2321.

[0192] In some embodiments, the upper surface of the first supporting arm avoiding part 2311 is recessed relative to the upper surface of the first fixed part 221, and the height difference between the upper surface of the first supporting arm avoiding part 2311 and the upper surface of the first fixed part 221 is greater than or equal to the thickness of the first supporting arm 6111. When the unlocking component 600 is in the unlocking position, the upper surface of the first supporting arm 6111 does not exceed the upper surface of the first fixed part 221.

[0193] In some embodiments, the upper surface of the second arm avoiding portion 2321 is recessed relative to the upper surface of the second fixed portion 222, and the height difference between the upper surface of the second arm avoiding portion 2321 and the upper surface of the second fixed portion 222 is greater than or equal to the thickness of the first arm 6111. When the unlocking component 600 is in the unlocking position, the upper surface of the first arm 6111 does not exceed the upper surface of the second fixed portion 222.

[0194] In some embodiments, one end of the first fixed portion 221 is formed with a first pull ring avoiding portion 2214, which is formed by partially recessing one end of the first fixed portion 221. The first pull ring avoiding portion 2214 is close to the second fixed portion 222, and the first pull ring avoiding portion 2214 is used to avoid one end of the bending portion 6115, thereby reducing the risk of interference between the bending portion 6115 and the first fixed portion 221.

[0195] In some embodiments, one end of the second fixed portion 222 is formed with a second pull ring avoiding portion 2224, which is formed by partially recessing one end of the second fixed portion 222. The second pull ring avoiding portion 2224 is close to the first fixed portion 221, and the second pull ring avoiding portion 2224 is used to avoid the other end of the bending portion 6115, thereby reducing the risk of interference between the bending portion 6115 and the second fixed portion 222.

[0196] In some embodiments, the left end of the first upper side plate 20121 is provided with a third recessed area 240, and the second arm 6112 is located in the third recessed area 240. The step formed by the third recessed area 240 limits the side wall of the second arm 6112, preventing the pull ring from exceeding the original position during the unlocking recovery stage.

[0197] The corresponding position of the second upper side plate 20122 can be provided with a fourth recessed area 250, and the fourth arm 6114 is located in the fourth recessed area 250. The step formed by the fourth recessed area 250 limits the side wall of the fourth arm 6114, preventing the pull ring from exceeding the original position during the unlocking recovery stage.

[0198] The surface of the supporting plate 2016 is recessed to form a fifth recessed area 260, and the third arm 6113 is located in the fifth recessed area 260. The step formed by the fifth recessed area 260 limits the side wall of the third arm 6113, preventing the pull ring from exceeding the original position during the unlocking recovery stage.

[0199] In some embodiments, the second recessed area 230, the third recessed area 240, the fourth recessed area 250, and the fifth recessed area 260 form a pull ring mounting portion. The first clamping shaft 211 is formed in the third recessed area 240, and the second clamping shaft 212 is formed in the fourth recessed area 250.

[0200] Figure 12A For a partial view of another upper shell according to some embodiments,Figure 12B is a cross-sectional view of another upper housing according to some embodiments. As shown in Figure 12A and Figure 12B In some embodiments, one end of the first fixed portion 221 is formed with a first avoiding surface 2215, which is located at the side of the first pull ring avoiding portion 2214. The first avoiding surface 2215 can be used to avoid the first connecting surface 62231, and can also be used as a guide for assembling the unlocking member 620 with the mounting base 220.

[0201] In some embodiments, one end of the second fixed portion 222 is formed with a second avoiding surface 2225, which is located at the side of the second pull ring avoiding portion 2224. The second avoiding surface 2225 can be used to avoid the second connecting surface 62241, and can also be used as a guide for assembling the unlocking member 620 with the mounting base 220.

[0202] In some embodiments, the top surface of the cover plate 2011 is formed with a first guide groove 20111. The first guide groove 20111 can extend from one end of the cover plate 2011 to below the first avoiding groove 2211. The first guide groove 20111 has a guiding effect, which facilitates the assembly of the first elastic member 631 into the first avoiding groove 2211, and can limit the first elastic member 631 during deformation, so that the first elastic member 631 deforms more uniformly.

[0203] In some embodiments, the top surface of the cover plate 2011 is formed with a second guide groove 20112. The second guide groove 20112 can extend from one end of the cover plate 2011 to below the third avoiding groove 2221. The second guide groove 20112 has a guiding effect, which facilitates the assembly of the second elastic member 632 into the third avoiding groove 2221, and can limit the second elastic member 632 during deformation, so that the second elastic member 632 deforms more uniformly.

[0204] Figure 13A is a partial view of another upper housing according to some embodiments, Figure 13B is a partial enlarged view of another upper housing according to some embodiments. As shown in Figure 13A and Figure 13B In some embodiments, one end of the first fixed portion 221 is formed with a first assembly portion 2017, which is located at the edge of one side of the cover plate 2011 and extends along the length direction of the cover plate 2011. The first assembly portion 2017 is used to assemble the first assembly protrusion 6241, and can limit the first assembly protrusion 6241, thereby facilitating the movement of the unlocking member 620 along the length direction of the cover plate 2011. Exemplarily, one end of the first assembly portion 2017 can be flush with one end of the cover plate 2011.

[0205] In some embodiments, one end of the second fixing portion 222 is formed with a second assembly portion 2018, which is located at the edge of the cover plate 2011 on the other side, and extends along the length direction of the cover plate 2011.

[0208] Figure 14A A cross section of an upper shell and an unlocking member according to some embodiments Figure 1 , Figure 14B A cross section of an upper shell and an unlocking member according to some embodiments Figure 2 , Figure 14C A cross section of an upper shell and an unlocking member according to some embodiments Figure 3 . Wherein, Figure 14A and Figure 14B is a cross section view when the unlocking member 600 is in the locked position, Figure 14C is a cross section view when the unlocking member 600 is in the unlocked position.

[0209] When the unlocking member 600 is in the locked position, the first branch 6111 is perpendicular to the cover plate 2011 with the bent portion 6115 above the second recessed area 230. At this time, the second end of the unlocking body 621 is located on the left side of the cooperating buckle 1061.

[0210] During the unlocking process, the pull ring 610 rotates around the card shaft 210, and the first branch arm 6111 and the bending part 6115 move to the lower right around the rotation shaft by pulling the pull ring 610 to the upper left. The contact between the reinforcing part 61152 and the unlocking part 620 gradually changes to the contact between the bending part 61151 and the unlocking part 620, so as to push the unlocking part 620 to move to the right. The guide part moves from left to right, so that the matching protrusion 2013 is embedded between the first elastic sheet guide part 6211 and the second elastic sheet guide part 6212, so that both ends of the matching buckle 1061 are lifted.
