Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to a protective shell and an electronic equipment component. Background Art

[0002] With the rapid development of electronic devices, electronic devices have become an indispensable part of people's lives. When using electronic devices, especially portable and mobile terminal devices, users pay more and more attention to the protection of the devices. Protective cases used in electronic devices have become one of the indispensable accessories. For example, taking mobile phones as an example, there are currently many types of mobile phone protective cases. Users can put mobile phone protective cases on their mobile phones to protect their mobile phones, thereby reducing or preventing scratches or falls on the mobile phones.

[0003] At present, in order to improve the portability of electronic devices, protective cases with hand straps are very common. For example, a hand strap is fixed on the shell of a mobile phone protective case, so that during use, the user can hang the mobile phone on the wrist through the hand strap, thereby realizing convenient carrying of mobile phones and other electronic devices and reducing the probability of electronic devices falling off and being lost. Among them, the hand strap on the protective case is mostly fixed to the shell of the protective case by riveting or spot gluing and other non-detachable methods.

[0004] However, the hand strap on the protective case is designed to be non-detachable, which cannot meet the need for disassembly when the hand strap is not needed, and it is difficult to replace the hand strap separately, which affects the applicability and convenience of the protective case and reduces the user experience. Summary of the invention

[0005] The present application provides a protective case and an electronic device assembly, wherein the shell belt and assembly assembly of the protective case are both detachable, which can meet the needs of various usage scenarios, expand the scope of applicable scenarios of the protective case, and effectively improve the convenience of the protective case.

[0006] The first aspect of the present application provides a protective case, which at least includes a shell belt, two shells and two assembly components. The shell belt has two connection ends, and the two connection ends are respectively connected to the two assembly components. The two assembly components are respectively detachably connected to the two shells. The assembly connection between the shell belt and the shell is realized by the assembly component, and the detachability of the assembly component and the shell enables the shell belt to be detachably connected to the shell, so as to meet the needs of small space storage, wireless charging and other scenarios that do not require a shell belt, greatly improving the applicable scene range and convenience of the protective case, and improving the user experience. Moreover, the assembly component can also be removed from the shell, so that the protective case does not have a shell belt and accessories for realizing the assembly of the shell belt. The protective case can be used as a conventional protective case, which improves the aesthetics of the entire protective case, and is more convenient to realize small space storage, wireless charging and fitting placement, etc., with better convenience, meeting the high experience needs of users.

[0007] In one possible implementation, the connecting end is detachably connected to the assembly component, that is, the shell strap can be detached from the shell body alone without removing the assembly component, so that the protective shell can be used as a protective shell without the shell strap, which is conducive to the rapid disassembly and installation of the shell strap, and is convenient to meet the needs of separate replacement of the shell strap, etc.

[0008] In one possible implementation, the assembly component includes a first assembly component and a second assembly component, the connecting end is detachably connected to the first assembly component, and the second assembly component is detachably connected to the shell. The detachable connection between the shell belt and the assembly component is achieved through the first assembly component, and the detachable connection between the entire assembly component and the shell is achieved through the second assembly component.

[0009] Moreover, the first assembly part is movably arranged on the second assembly part, so that the first assembly part can move relative to the second assembly part and the shell, which means that the shell belt connected to the first assembly part has a higher degree of freedom of movement relative to the second assembly part and the shell, which is convenient for realizing flexible carrying of electronic equipment components through the shell belt, and is conducive to further improving the convenience of the protective shell. Moreover, the protective shell can be suitable for foldable electronic devices, and the two shells can be respectively mounted on the two main bodies of the electronic device. The two shells can be folded or unfolded as the two main bodies of the electronic device are folded or unfolded, so that the shell belt and the first assembly part have a higher degree of freedom of movement relative to the shell and the second assembly part, and can also reduce or avoid the influence of the shell belt and assembly components on the rotation of the two shells, ensuring that the rotation requirements of the electronic device and the shell are met, and then ensuring the smoothness of the folding and unfolding process of the electronic device, which is conducive to improving the user experience.

[0010] In a possible implementation, it also includes a first magnet and a second magnet for cooperating with the first magnet, the first magnet is arranged on the connection end, the second magnet is arranged on the first assembly part, and the connection end realizes a detachable connection with the first assembly part through the cooperation of the first magnet and the second magnet. The detachable connection between the shell belt and the first assembly part (shell) is realized by magnetic cooperation, so that the shell belt can be disassembled and installed conveniently, and the shell belt can be quickly and conveniently disassembled and installed without the aid of any tools, which is conducive to further improving the convenience of the protective shell and enhancing the user experience.

[0011] In a possible implementation, the connection end and the first assembly part can be plugged in and out, and when the connection end and the first assembly part are plugged in, the first magnet and the second magnet attract each other. Under the condition of achieving detachability, the plug-in and pull-out cooperation between the connection end and the first assembly part is conducive to improving the connection stability between the shell belt and the first assembly part, and can reduce the risk of the shell belt and the first assembly part being separated and falling off during use.

[0012] In a possible implementation, the shell belt further includes a reinforcement member, which is fixed to the end of the connection end, and the connection end can be plugged and unplugged with the first assembly part through the reinforcement member. The reinforcement member can be a structural member with a certain hardness, which can increase the strength of the connection end, facilitate the plugging and unplugging of the shell belt with the first assembly part, and can improve the smoothness of the entire plugging and unplugging process, which is conducive to improving the user experience.

[0013] In one possible implementation, a plug-in slot is provided on the first assembly part, and the reinforcement member can be plugged in and out of the plug-in slot. The plug-in slot can play a certain limiting role on the reinforcement member to ensure the connection stability when the connecting end is plugged in with the first assembly part, so as to improve the assembly strength of the shell belt.

[0014] The first magnet is fixed on the reinforcement member, and the second magnet is fixed in the plug-in slot. When the reinforcement member is pluggable and arranged on the plug-in slot, it is easier to achieve mutual attraction between the first magnet and the second magnet, thereby achieving connection between the shell belt and the first assembly member.

[0015] In a possible implementation, one of the reinforcement member and the insertion slot has a positioning slot, and the other of the reinforcement member and the insertion slot has a positioning protrusion for plugging and cooperating with the positioning slot, and when the reinforcement member is plugged into the insertion slot, the positioning protrusion is inserted into the positioning slot. The cooperation between the positioning protrusion and the positioning slot can play a good guiding and positioning role, so that the connection end can be accurately inserted into the insertion slot, and the first magnet and the second magnet can be accurately aligned and maintain a strong attraction, so as to realize the rapid and accurate assembly of the shell belt, which is conducive to improving the convenience of the protective shell.

[0016] In a possible implementation, the second assembly includes an installation component and a locking component. The installation component is detachably connected to the shell, and the locking component is detachably connected to the installation component. The locking component can lock and unlock the assembly and separation between the installation component and the shell.

[0017] The second assembly part includes a locked state and an unlocked state. When the second assembly part is in the locked state, the locking component is connected to the installation component, and an external force is directly applied to the installation component. The installation component and the shell cannot move relative to each other, and the installation component is fixed on the shell, so that the second assembly part is fixed to the shell, and the entire assembly component can be assembled on the shell.

[0018] When the second assembly is in the unlocked state, the locking component is separated from the mounting component, and the mounting component can move relative to the shell. By applying external force to the mounting component, it can be moved relative to the shell and separated from the shell, and the mounting component is disassembled and separated from the shell, thereby realizing the disassembly of the entire second assembly from the shell. In other words, by locking or unlocking the locking component, the mounting component and the shell can be stably connected, and the mounting component and the shell can be movable and disassembled, thereby realizing the assembly and disassembly of the second assembly and the shell, and directly acting on the mounting component to make it move relative to the shell can realize the disassembly of the entire second assembly, which is conducive to the installation and disassembly of the second assembly without the assistance of tools.

[0019] In a possible implementation, the mounting assembly includes two mounting parts, the first ends of the two mounting parts are detachably connected to the shell, and the second ends of the two mounting parts are detachably connected to the two ends of the locking component. The second assembly part can be a U-shaped frame in the locked state, which has high aesthetics and is conducive to the sleeve assembly between the second assembly part and the first assembly part. The first assembly part can be directly sleeved on the second assembly part from one end of the second assembly part. The first assembly part, the second assembly part and the shell can be assembled together after being formed separately, so that the assembly of the entire protective shell has good flexibility and is easy to produce.

[0020] In a possible implementation, the locking component includes a first limiting member, and the two ends of the first limiting member are respectively pluggable with the second ends of the two mounting members. When the two ends of the first limiting member are plugged into the second ends of the two mounting members, the fixing of the locking component and the mounting assembly is realized, so that the second assembly part is in a locked state, and the assembly requirements of the second assembly part and the shell are met. The two ends of the first limiting member are respectively pulled out and separated from the first ends of the two mounting members, so that the disassembly and separation of the locking component and the mounting assembly is realized, and the second assembly part is in an unlocked state, so that the mounting part can be moved and removed from the shell. In other words, the second assembly part is unlocked by pulling out and separating the locking component from the mounting assembly, and external forces are applied to the two mounting members respectively to make them move, so that the disassembly and separation of the mounting part and the shell can be realized, and the disassembly of the second assembly part (i.e., the entire assembly component, shell belt) is realized, and the disassembly and installation of the entire assembly component can be realized without the help of tools, which is more convenient and quick, and the convenience of the protective shell is significantly improved.

[0021] In a possible implementation, both ends of the first position-limiting member have plug-in portions, and the two mounting members have guide rail portions, respectively. The starting end of the guide rail portion is located on the end surface of the mounting member facing away from the housing, and the plug-in portion is pluggably arranged on the guide rail portion through the starting end. By making the starting end located on the end surface of the mounting member facing away from the housing, the housing can be prevented from affecting the plugging and unplugging of the first position-limiting member, making it easier to plug and unplug the first position-limiting member and the mounting assembly, and to install and disassemble the second assembly.

[0022] In a possible implementation, the mounting member has an abutment portion, which is located at the rear end of the guide rail portion. When the second assembly member is in a locked state, the plug-in portion is plugged into the guide rail portion, and the plug-in portion abuts against a surface of the abutment portion facing the starting end. The abutment portion further limits the first position-limiting member, so that the first position-limiting member will not fall out of the mounting member when subjected to a force toward the housing in the thickness direction during use, which is conducive to further improving the firmness between the locking member and the mounting assembly.

[0023] In a possible implementation, one of the plug-in portion and the guide rail portion is a groove portion, and the other is a protrusion portion. The groove portion and the protrusion portion cooperate with each other to play a limiting role. For example, taking the extension direction of the guide rail portion parallel to the thickness direction as an example, the cooperation between the groove portion and the protrusion portion can limit the movement of the first limiter in the width direction and the length direction. During use, the first limiter will not fall out of the installation assembly even if it is subjected to forces in the width direction and the length direction, thereby improving the connection stability between the locking component and the installation assembly, thereby improving the connection strength between the assembly assembly (and the shell belt) and the shell, and improving the reliability of the protective shell.

[0024] In a possible implementation, the locking component further includes a second limiting component, and the second limiting component is detachably connected to the first limiting component. When the second assembly is in a locked state, the first limiting component is connected to the second limiting component, and the two ends of the second limiting component are respectively abutted against the side of the two mounting components facing the shell, and the first limiting component can be limited by the second limiting component. During use, the force that pushes up along the thickness direction away from the shell acts on the second limiting component. Since the second limiting component abuts against the side of the mounting component facing the shell, the second limiting component and the first limiting component will not fall out of the mounting assembly, which further improves the firmness between the locking component and the mounting assembly and improves the assembly stability of the second assembly.

[0025] When the second assembly is in an unlocked state, the first limiting member is disassembled and separated from the second limiting member, and the second limiting member is disassembled and separated from the mounting member, meeting the disassembly and separation requirements of the locking component and the mounting component, so that the second assembly is in an unlocked state.

[0026] In a possible implementation, a positioning groove is provided on a surface of the mounting member facing the housing, and when the second assembly part is in a locked state, both ends of the second position-limiting member are located in the positioning groove. The positioning groove can play a guiding and limiting role, so that the second position-limiting member can be conveniently and quickly assembled to the mounting assembly, thereby facilitating the convenient and rapid assembly of the second assembly part.

[0027] In a possible implementation, a third magnet and a fourth magnet are further included, the third magnet is fixed on the first limiter, and the fourth magnet is fixed on the second limiter, and when the second assembly part is in a locked state, the third magnet and the fourth magnet attract each other. The magnetic cooperation of the third magnet and the fourth magnet realizes a detachable connection between the first limiter and the second limiter, making the installation and removal of the first limiter and the second limiter more convenient and quick, and easy to implement without the aid of any tools.

[0028] In a possible implementation, the assembly component further includes two fasteners, and the second ends of the fasteners are threadedly engaged with the first end of the mounting member.

[0029] When the second assembly part is in a locked state, the first end of the fastener abuts against the side of the shell facing away from the assembly component, and the second end of the fastener passes through the shell and is fixed to the mounting part, thereby achieving the fixation of the mounting part and the shell, so that the second assembly part (assembly component) is assembled to the shell.

[0030] When the second assembly part is in the unlocked state, the mounting part can rotate and slide relative to the second end of the fastener, and the mounting part and the fastener are separated, so that the second assembly part and the fastener can be removed from the shell. In other words, by rotating the mounting part to make it slide relative to the fastener, the second assembly part and the shell can be disassembled and separated, and the entire assembly component can be better disassembled and installed without the help of tools, which is conducive to further improving the convenience of the protective shell, and the structural design is simple and easy to implement.

[0031] In a possible implementation, a contact groove is provided on a surface of the housing that faces away from the second assembly part, and when the second assembly part is in a locked state, the first end of the fastener contacts the bottom of the contact groove. The contact groove can limit the first end of the fastener, and the first end of the fastener is accommodated in the contact groove, which can prevent the first end of the fastener from protruding in the accommodation cavity of the housing and causing damage to the electronic device. The contact groove is also conducive to the positioning and assembly of the fastener, which helps to improve assembly efficiency.

[0032] In a possible implementation, one of the inner peripheral side wall of the abutment groove and the outer peripheral side wall of the first end of the fastener has a limiting protrusion, and the other has a limiting groove, and the limiting protrusion is pluggable and arranged in the limiting groove. The cooperation of the limiting protrusion and the limiting groove can fix the fastener and the housing, so that the fastener cannot rotate relative to the housing, and then when the mounting part is rotated, the fastener and the housing remain relatively fixed, and the fastener can be fixed without manual pressing, etc., which is more conducive to the convenient disassembly of the second assembly part and improves the user experience.

[0033] In a possible implementation manner, the shapes of the first end of the fastener and the abutment groove include at least a circle and a polygon.

[0034] In one possible implementation, the assembly component is a metal part, which has a good texture, is conducive to improving the aesthetics of the entire protective shell, and has good strength, can better realize the assembly of the shell belt, and ensure the assembly strength.

[0035] In a possible implementation, an assembly hole is provided on the first assembly part, and the first assembly part is sleeved on the second assembly part through the assembly hole.

[0036] The second aspect of the present application provides an electronic device assembly, including an electronic device and any of the above-mentioned protective shells, the electronic device including a first body, a folding device and a second body, the first body and the second body are respectively located on both sides of the folding device, and the first body and the second body are rotatably matched through the folding device, and the two shells are respectively sleeved on the first body and the second body. By including a protective shell, the shell belt and assembly components of the protective shell can be removed, which can meet the use requirements of various scenarios, such as facilitating small space storage, wireless charging, etc., thereby improving the convenience of use of the entire electronic device assembly and meeting the user's high experience requirements.

[0073] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0074] An embodiment of the present application provides a protective case that can be applied to an electronic device. The protective case can accommodate and protect the electronic device to reduce or avoid damage to the electronic device due to long-term use or in scenarios such as falling, friction, etc.

[0075] With the rapid development of electronic devices, protective cases for electronic devices have become one of the indispensable accessories in various terminal electronic products. In the embodiments of the present application, the electronic device equipped with the protective case is an electronic device component.

[0076] It is understandable that the electronic device assembly may also include other structural parts or accessories. For example, the electronic device assembly may also include a protective film, a stylus pen, a touch keyboard, a Bluetooth headset, etc.

[0077] Among them, electronic devices may include but are not limited to mobile phones, tablet computers, laptops, ultra-mobile personal computers (UMPCs), handheld computers, watches, e-readers, touch-screen TVs, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, vehicle-mounted devices, etc.

[0078] The electronic device may be a foldable electronic device, for example, the electronic device may be a foldable mobile phone that can be folded or unfolded. The protective case may be mounted on the foldable mobile phone, and the protective case may be folded or unfolded as the electronic device is folded or unfolded.

[0079] In the embodiments of the present application, the application of a protective case to a foldable mobile phone is taken as an example for description.

[0080] Exemplarily, a foldable electronic device may include at least two bodies and a folding device, such as a first body, a folding device, and a second body. The first body and the second body may be located on both sides of the folding device, respectively, and the first body and the second body may be connected to the folding device, respectively.

[0081] The folding device may be a hinge or other device, and the first body and the second body may be rotatably matched through the folding device, so that the first body and the second body can rotate relative to each other, thereby realizing the folding or unfolding of the electronic device.

[0082] Figure 1 A schematic diagram of a protective shell in a folded state provided in an embodiment of the present application, Figure 2 A schematic structural diagram of a protective shell in a flattened state provided in an embodiment of the present application.

[0083] Accordingly, see Figure 1As shown, the protective shell 100 may include at least two shells 110, such as a shell 10 and a shell 20, wherein a receiving cavity may be formed in the shell 10 and the shell 20, and the shell 10 may be mounted on the first body of the electronic device, so that the first body may be at least partially located in the receiving cavity of the shell 10. The shell 20 may be mounted on the second body of the electronic device, so that the second body may be at least partially located in the receiving cavity of the shell 20. The first body and the second body of the electronic device rotate relative to each other, which can drive the shell 10 and the shell 20 to rotate relative to each other, so that the protective shell 100 can be folded or unfolded as the electronic device is folded or unfolded.

[0084] It should be noted that the shell 10 and the shell 20 can be independently arranged, that is, the shell 10 and the shell 20 are two separate structural members, and the two relatively independent shells are respectively mounted on the two main bodies of the electronic device, and the two shells rotate relative to each other as the two main bodies of the electronic device rotate. Of course, in some other examples, the shell 10 and the shell 20 can also be matched and connected together and can achieve relative rotation. For example, the two shells can be connected together by a rotating mechanism, and the two shells can achieve rotational cooperation through the rotating mechanism, so that the two shells can rotate relative to each other as the two main bodies of the electronic device rotate, ensuring that the protective shell 100 can be folded or unfolded as the electronic device is folded or unfolded. In the embodiment of the present application, the shell 10 and the shell 20 are independently arranged as an example for explanation.

[0085] Exemplarily, the first body and the second body of the electronic device can be folded relative to each other to a closed state. For example, when the first body and the second body are in the closed state, the two can be completely closed to be parallel to each other (a slight deviation is allowed). At this time, the electronic device is in a closed state, also called a folded state. The housing 10 and the housing 20 of the protective case 100 can also be folded relative to each other to a closed state as the first body and the second body are folded, see Figure 1 As shown, the housing 10 and the housing 20 are folded together to be parallel to each other (a slight deviation is allowed), and the protective shell 100 can be in a closed state (folded state).

[0086] Accordingly, the first body and the second body of the electronic device can be relatively unfolded to an open state. For example, when the first body and the second body are in the open state, the angle between them can be approximately 180° (a slight deviation is allowed). At this time, the electronic device is in the open state, also called the flattened state. Figure 2 As shown, the shell 10 and the shell 20 can also be relatively opened as the first body and the second body are unfolded, and the shell 10 and the shell 20 can be approximately 180° apart (a slight deviation is allowed), and the protective shell 100 can also be in a flattened state.

[0087] The first body and the second body of the electronic device can be relatively rotated (folded or unfolded) to an intermediate state, so that the electronic device is in the intermediate state, the housing 10 and the housing 20 can also be relatively rotated to the intermediate state, and the protective shell 100 can also be in the intermediate state. It can be understood that the intermediate state can be any state between the closed state and the open state.

[0088] In the present application embodiment, Figure 1 and Figure 2 As shown, when the protective shell is in a flattened state or a folded state, the width direction of the shell 110 is the x direction, the length direction of the shell 110 is the y direction, and the thickness direction of the shell 110 is the z direction.

[0089] The length, width, and thickness in the embodiments of the present application are only for convenience of description and do not imply any limitation on the size. For example, the length may be greater than, equal to, or less than the width.

[0090] The display screen of the electronic device may be a foldable flexible display screen, and the flexible display screen may be laid on the first body, the folding device and the second body. For example, the flexible display screen may be located on the same side surface of the first body, the folding device and the second body.

[0091] Among them, the electronic device can be a device with an inwardly folded display screen, that is, the flexible display screen can be arranged on the inner surface of the first body, the folding device, and the second body. It should be noted that when the electronic device is in a folded state, the two adjacent and opposite surfaces of the first body and the second body are the inner surfaces of the first body and the second body, and the surface of the folding device on the same side as the inner surfaces of the first body and the second body is the inner surface of the folding device. The two surfaces of the first body and the second body facing each other are the outer surfaces of the first body and the second body, respectively, and the surface of the folding device on the same side as the outer surfaces of the first body and the second body is the outer surface of the folding device.

[0092] Exemplarily, the first body and the second body may both include a back cover and a frame, the frame is arranged on the back cover, and the back cover and the flexible display screen may be respectively located on two opposite sides of the frame, that is, the side of the back cover facing away from the flexible display screen may serve as the outer surface of the first body and the second body.

[0093] When the protective shell 100 is assembled on an electronic device, the shell 10 can be buckled on the frame of the first body and cover (all or part of) the frame and back cover of the first body, and the shell 20 can also be buckled on the frame of the second body and cover (all or part of) the frame and back cover of the second body, thereby protecting the electronic device through the shell of the protective shell 100.

[0094] Exemplarily, the housing 110 may include a back housing and a side housing, see Figure 1 and Figure 2 As shown, taking the shell 10 as an example, the shell 10 may include a back shell 101 and a side shell 102. The side shell 102 is located on the peripheral side of the back shell 101. The back shell 101 and the side shell 102 together form a accommodating cavity of the shell 10. In the electronic device assembly, the side shell 102 can be clamped on the frame of the first body of the electronic device and cover the frame. The back shell 101 can be located on the side of the back cover of the first body that is away from the flexible display screen and cover the back cover.

[0095] At present, in order to improve the portability of electronic device components, especially for mobile phones that become smaller in size after being folded, protective cases equipped with accessories such as hand straps and chain straps that are easy to carry are becoming more and more popular among the public. For example, taking a protective case with a hand strap as an example, a hand strap is fixed on the shell of the protective case, and a user can conveniently carry the electronic device component with the hand strap, such as using the hand strap to carry the electronic device component on the hand, etc., which can also effectively reduce or prevent the occurrence of falling, loss, etc. of the electronic device.

[0096] However, common accessories such as hand straps and chain straps are mostly fixed to the shell of the protective case by riveting / glueing and other non-detachable methods. In scenarios where a hand strap is not needed, such as when the electronic device components need to be stored in a small space such as a portable bag or pocket, or when the electronic device components need to be attached to the charging stand during wireless charging, the hand strap is difficult to remove from the shell. The large and protruding hand strap will cause many inconveniences and cannot meet the needs of the above-mentioned small space storage, wireless charging attachment, etc. In addition, the hand strap and the shell are difficult to replace separately, which will reduce the applicable scenario range of the protective case, reduce the convenience of the protective case, and thus greatly reduce the user experience.

[0097] In addition, wrist straps and the like are assembled to the shell by riveting or other assembly parts. Even if the wrist strap is removed, the assembly parts will still remain on the shell, and the protective shell cannot be used as a regular protective shell (without accessories), affecting the aesthetics of the protective shell. Moreover, the presence of raised assembly parts will also affect the storage, stable placement, wireless charging and placement of electronic device components, etc., and will also reduce the applicability and convenience of the protective shell.

[0098] Based on this, an embodiment of the present application provides a protective shell, in which the shell belt is assembled on the shell through an assembly component, and the assembly component is connected to the shell in a detachable manner, so that the shell belt and the shell can be detached to meet the needs of scenarios where the shell belt is not needed, etc., which greatly improves the applicable scenario range and convenience of the protective shell and improves the user experience. Moreover, the assembly component used to fix the shell belt can also be removed from the shell, so that the protective shell can be used as a conventional protective shell (without accessories on the shell), further improving the applicable scope and convenience of the protective shell. In addition, the removal of the assembly component and the shell belt can be achieved without the aid of tools, and the removal and installation are convenient and quick. The shell belt and the assembly component can be quickly disassembled and installed at any time, further enhancing the convenience and meeting the user's high experience needs.

[0099] Specifically, continue to combine Figure 1 and Figure 2 As shown, the protective case 100 includes a case belt 30, which is mounted on the housing 110. The case belt 30 can facilitate users to carry electronic device components, such as in Figure 1 When the protective case 100 (and the electronic device) shown in FIG. 1 is in a folded state, the user can carry the entire electronic device assembly by holding or wearing the case strap 30. Figure 2 When the protective case 100 (and the electronic device) shown in the figure is in a flattened state, the user can also carry the electronic device components through the case strap 30.

[0100] Among them, the shell belt 30 can have two connection ends 310, such as the two connection ends 310 can be a connection end 31 and a connection end 32 respectively, the connection end 31 and the connection end 32 can be the two ends of the shell belt 30 along its extension direction respectively, and the shell belt 30 can be connected to the two shells 110 through the two connection ends 310.

[0101] The protective shell can also include two assembly components 410. The two connecting ends 310 of the shell strap 30 can be respectively assembled to the two shells 110 through the two assembly components 410, so that the protective shell 100 is more beautiful as a whole, and it is beneficial to evenly distribute the drag force generated during carrying, reduce the impact on the connection strength between the shell strap 30 and the shell 110, ensure the stability of the shell strap 30, and help to extend the service life of the protective shell 100.

[0102] Specifically, the two connecting ends 310 of the shell belt 30 can be connected to the two assembly components 410 respectively, and the two assembly components 410 can be connected to the two shells 110 respectively, so as to fix the shell belt 30 and the shell 110 together.

[0103] For example, see Figure 2As shown, the two assembly components 410 are assembly component 40 and assembly component 50, respectively. The connection end 31 can be connected to the assembly component 40, and the assembly component 40 can be connected to the shell 10 to assemble the shell belt 30 with the shell 10. The connection end 32 can be connected to the assembly component 50, and the assembly component 50 can be connected to the shell 20 to assemble the shell belt 30 with the shell 20.

[0104] It is understandable that when the assembly component 410 is assembled and connected with the housing 110, the assembly component 410 can be fixed on the back side of the housing 110 (the side facing away from the accommodating cavity), such as Figure 2 As shown in FIG. 1 , taking the assembly component 40 as an example, the assembly component 40 is protrudingly fixed on the back side of the back shell 101 .

[0105] The connection between the assembly component 410 and the housing 110 is a detachable connection, that is, the assembly component 410 can be assembled and fixed on the housing 110, so that the shell belt 30 connected to the assembly component 410 is also fixedly assembled to the housing 110. Alternatively, the assembly component 410 can also be removed from the housing 110, so that the shell belt 30 connected to the assembly component 410 is also removed from the housing 110, so that the shell belt 30 is detachable, meeting the needs of scenes where the shell belt 30 is not needed, such as small space storage, ensuring wireless charging fit, etc., significantly improving the applicable scene range of the protective case 100, improving the convenience of the protective case 100, and helping to improve the user experience.

[0106] Moreover, the assembly component 410 and the shell strap 30 can be removed from the shell body 110, which means that the protective shell 100 does not have a shell strap and accessories for assembling the shell strap. The protective shell 100 can be used as a conventional protective shell, which is beneficial to improve the aesthetics of the entire protective shell 100, and is more convenient for storing electronic device components, wireless charging and placement, etc., with better convenience to meet the user's high experience needs.

[0107] For example, see Figure 2 As shown, in a scenario where the shell belt 30 is needed, such as when the shell belt 30 is needed to realize convenient carrying of electronic equipment components, the two connection ends 310 of the shell belt 30 can be respectively connected and assembled with the assembly components 410, and the assembly components 410 are respectively fixedly connected with the housing 110. For example, the connection end 31 is connected with the assembly component 40, the assembly component 40 is fixedly assembled with the housing 10, the connection end 32 is connected with the assembly component 50, and the assembly component 50 is fixedly assembled with the housing 20, so that the shell belt 30 is assembled and fixed on the housing 110, and the protective case 100 can be used as a protective case with the shell belt 30.

[0108] Figure 3 A schematic diagram of disassembling and assembling components and a shell belt in a protective shell provided in an embodiment of the present application.

[0109] See also Figure 3 As shown, in a scenario where the shell band 30 and the assembly component 410 are not needed, such as when it is necessary to store electronic equipment components in a smaller space, the assembly component 410 can be disassembled and separated from the shell 110, for example, the assembly component 40 is disassembled and separated from the shell 10, and the assembly component 50 is disassembled and separated from the shell 20, thereby disassembling and separating the shell band 30 and the two assembly components 410 from the shell 110, and the protective shell 100 can be used as a conventional protective shell without the shell band and accessories.

[0110] Figure 4 A schematic diagram of separately removing a shell strap from a protective shell provided in an embodiment of the present application.

[0111] In the embodiment of the present application, the shell belt 30 can also be disassembled separately. Specifically, the connecting end 310 of the shell belt 30 can be detachably connected to the assembly component 410, that is, the shell belt 30 can be connected and assembled on the assembly component 410 (refer to Figure 1 and Figure 2 Alternatively, see Figure 4 As shown, the shell belt 30 can also be separated from the assembly component 410, and the shell belt 30 can be separated from the housing 110 without disassembling the assembly component 410. This is conducive to the rapid disassembly and installation of the shell belt 30, and is convenient for meeting the needs of separate replacement of the shell belt.

[0112] For example, in a scenario where the shell belt 30 is required, the assembly component 40 and the assembly component 50 are fixedly assembled on the housing 10 and the housing 20, respectively, and the connection end 31 and the connection end 32 of the shell belt can be connected to the assembly component 40 and the assembly component 50, respectively (refer to Figure 1 and Figure 2 As shown), the shell belt 30 is fixedly assembled on the housing 110, and the protective shell 100 can also be used as a protective shell with a shell belt.

[0113] In the scenario where the shell belt 30 needs to be removed separately, see Figure 4 As shown, the connection end 31 of the shell band 30 can be detached from the assembly component 40, and the connection end 32 can be detached from the assembly component 50, so that the shell band 30 can be removed from the shell 110, and the protective shell 100 can be used as a protective shell without a shell band. It can be understood that at this time, the shell 110 is equipped with the assembly component 410, and the assembly component 410 can be removed or kept assembled on the shell 110 according to needs.

[0114] Among them, continue to see Figure 4As shown, the assembly component 410 may include a first assembly component 41 and a second assembly component 42. The first assembly component 41 is assembled on the second assembly component 42. The connecting end 310 of the shell band 30 can be detachably connected to the first assembly component 41, and the second assembly component 42 can be detachably connected to the shell 110. That is, the shell band 30 and the assembly component 410 can be detachably connected through the first assembly component 41, and the entire assembly component 410 can be detachably connected to the shell 110 through the second assembly component 42.

[0115] For example, Figure 4 Taking the assembly component 40 in the embodiment as an example, the connection end 31 of the shell belt 30 can be connected to the first assembly component 41 in a detachable manner, and the second assembly component 42 can be connected to the shell 10 in a detachable manner.

[0116] Among them, the first assembly part 41 can be assembled with the second assembly part 42 in a movable manner, so that the first assembly part 41 can be movable on the second assembly part 42, and the first assembly part 41 can be movable relative to the second assembly part 42 and the housing 110, which means that the shell belt 30 connected to the first assembly part 41 has a high degree of freedom of movement relative to the second assembly part 42 and the housing 110, which is convenient for flexible carrying of electronic device components through the shell belt 30, which is conducive to further improving the convenience of the protective shell 100. It can also reduce or avoid the influence of the shell belt 30 and the assembly component 410 on the rotation of the two housings 110, ensure that the rotation requirements of the electronic device and the housing 110 are met, and then ensure the smoothness of the folding and unfolding process of the electronic device, which is conducive to improving the user experience.

[0117] For example, see Figure 4 As shown, a mounting hole 411 may be opened on the first mounting part 41 , and the first mounting part 41 may be movably mounted on the second mounting part 42 through the mounting hole 411 .

[0118] It is understandable that the structures of the two assembly components 410 can be the same, and the detachable connection method between the shell belt 30 and the two assembly components 410, and the detachable connection method between the two assembly components 410 and the shell 110 can also be the same.

[0119] The two assembly components 410 can both be metal parts, that is, the molding materials of the first assembly part 41 and the second assembly part 42 in each assembly component 410 can be metal materials respectively, which have good texture, are beneficial to improving the aesthetics of the entire protective shell, and have good strength, can better realize the assembly of the shell belt, and ensure the assembly strength.

[0120] Of course, in some other examples, the assembly component 410 may also be a structural component formed of other types of materials, such as a plastic component.

[0121] The detachable connection between the first assembly member and the shell belt is described below.

[0122] There may be various ways of detachably connecting the shell band 30 and the first assembly part 41 . For example, in one example, the connecting end 310 of the shell band 30 may be detachably connected to the first assembly part 41 by magnetic cooperation.

[0123] Figure 5 for Figure 1 An enlarged view of the local structure of the cross section formed along the AA surface.

[0124] For example, the connection between the first assembly part 41 of the assembly assembly 40 and the connection end 31 of the shell belt 30 is taken as an example. Figure 5 As shown, the protective shell may further include a first magnet 60 and a second magnet 70. The first magnet 60 and the second magnet 70 may cooperate with each other, such as the first magnet 60 and the second magnet 70 may be attracted to each other and connected together. It can be understood that when an external force is applied to the first magnet 60 and / or the second magnet 70 in the opposite direction (opposite to the attraction force), and the applied external force is greater than the attraction force between the first magnet 60 and the second magnet 70, the first magnet 60 and the second magnet 70 may be separated from each other.

[0125] Among them, the first magnet 60 can be fixed on the connecting end 31, and the second magnet 70 can be fixed on the first assembly part 41. The connecting end 31 can realize the detachable connection between the shell belt 30 and the first assembly part 41 by cooperating with the first magnet 60 and the second magnet 70 on the first assembly part 41.

[0126] In a scenario where the shell belt 30 is needed, the first magnet 60 on the connecting end 31 is docked with the second magnet 70 on the first assembly part 41 so that the first magnet 60 and the second magnet 70 attract and cooperate with each other, thereby achieving the connection between the connecting end 31 and the first assembly part 41, and then assembling the shell belt 30 on the assembly component 40.

[0127] In the scenario where the shell belt 30 needs to be removed separately, the first magnet 60 of the connection end 31 can be separated from the second magnet 70 of the first assembly part 41 by applying force to the shell belt 30, that is, the connection end 31 of the shell belt 30 is removed from the first assembly part 41, and then the shell belt 30 is disassembled and separated from the assembly component 40. Disassembly and installation are convenient, and the shell belt 30 can be quickly and conveniently disassembled and installed without the aid of any tools, which is conducive to improving the convenience of the protective case and enhancing the user experience.

[0128] Of course, in some other examples, the shell band 30 and the first assembly part 41 can also be assembled by other detachable connection methods. For example, the connecting end of the shell band can be connected to the first assembly part by threaded connection, snap connection or hinge connection.

[0129] For example, the connecting end of the shell belt and the first assembly part may respectively have threaded holes, and the protective shell may also include a fixing part, on which an external thread may be formed, and the fixing part may be threadedly matched with the threaded holes on the connecting end and the first assembly part to achieve a detachable connection between the connecting end and the first assembly part.

[0130] Alternatively, a raised buckle may be formed on one of the connecting end of the shell belt and the first assembly part, and a slot that can be snap-fitted with the buckle may be formed on the other one, and the connecting end can be detachably connected to the first assembly part through the cooperation of the buckle and the slot.

[0131] It is understandable that in order to improve the connection strength between the shell belt and the first assembly part, the shell belt and the first assembly part can have a variety of detachable connection methods. For example, the shell belt can have a first magnet on the connection end, and the first assembly part has a second magnet that cooperates with the first magnet. Moreover, a buckle or a slot can be formed on the connection end. Correspondingly, a slot or a buckle can also be formed on the first assembly part. The connection end of the shell belt and the first assembly part can be detachably connected through the cooperation of the first magnet and the second magnet, and the connection end of the shell belt and the first assembly part can also be detachably connected through the cooperation of the buckle and the slot. In other words, the connection end of the shell belt and the first assembly part can be connected in at least two detachable ways. Under the condition that the shell belt is detachable, the connection strength of the shell belt and the first assembly part can be improved, and the electronic device can be reduced or avoided from falling off due to the separation of the shell belt and the shell during use, thereby improving the stability of use.

[0132] In order to better realize the assembly between the connection end of the shell belt and the first assembly part, the connection end of the shell belt and the first assembly part can be matched in a pluggable manner, that is, see Figure 5 As shown, the connection end 31 of the shell belt 30 can be plugged into the first assembly part 41 .

[0133] It is understandable that when the connection end 31 is plugged into the first assembly part 41, the connection end 31 can be connected with the first assembly part 41, such as the connection end 31 and the first assembly part 41 can be connected with each other through the above-mentioned magnetic connection, snap connection, etc. Figure 5As shown, when the connecting end 31 is plugged into the first assembly part 41, the first magnet 60 on the connecting end 31 and the second magnet 70 on the first assembly part 41 attract each other, so that the connecting end 31 and the first assembly part 41 are magnetically connected, thereby ensuring that the connecting end 31 can be well assembled and fixed with the first assembly part 41.

[0134] The connecting end 31 of the shell belt 30 can also be pulled off from the first assembly part 41 , and the fit between the connecting end 31 and the first assembly part 41 is removed, such as the first magnet 60 and the second magnet 70 are separated, so that the connecting end 31 is separated from the assembly component 40 .

[0135] Figure 6 A schematic diagram of the disassembled structure of a shell belt and a first assembly part in a protective shell provided in an embodiment of the present application.

[0136] Exemplary, combined Figure 6 As shown, a plug-in slot 412 may be formed on the first assembly part 41, and the end of the connection end 31 may be plugged and unplugged into the plug-in slot 412, so as to realize the pluggable setting between the shell belt 30 and the first assembly part 41. The plug-in slot 412 may play a certain limiting role on the connection end 31, and under the condition of realizing detachability, it is ensured that the shell belt 30 and the first assembly part 41 have a relatively high connection stability when plugged, and the risk of separation and falling off of the shell belt 30 and the first assembly part 41 during use may be reduced.

[0137] Of course, in some other examples, a plug-in slot may be formed on the connecting end 31 of the shell belt 30 , and the end of the first assembly part 41 may be plugged in and out of the plug-in slot to achieve a pluggable setting between the shell belt 30 and the first assembly part 41 .

[0138] It is understandable that, in order to improve the comfort of the user when using the shell belt 30 to carry the electronic device, the shell belt 30 can have a certain degree of softness, and the shell belt 30 includes a flexible member, for example, the shell belt 30 can include microfiber leather, such as the molding material of the shell belt 30 can be polyurethane leather (PU leather), etc. Of course, in some other examples, the shell belt 30 can also include other types of flexible members, such as braided fabric, flexible silicone, etc.

[0139] In order to facilitate the connection end 31 to be well plugged and unplugged with the first assembly part 41, continue to combine Figure 5 and Figure 6As shown, the shell belt 30 may also include a reinforcement member 33, which may be fixed on the end of the connection end 31. The connection end 31 may be pluggable with the first assembly part 41 through the reinforcement member 33, that is, the reinforcement member 33 may be plugged into the first assembly part 41, and the reinforcement member 33 may also be unplugged from the first assembly part 41. The reinforcement member 33 may be a structural member with a certain hardness, such as a metal member, etc. The reinforcement member 33 is arranged on the connection end 31, which can increase the strength of the connection end 31. The connection end 31 is pluggable with the first assembly part 41 through the reinforcement member 33, which is convenient for plugging and unplugging, and can improve the smoothness of the entire plugging and unplugging process, which is conducive to improving the user experience.

[0140] Among them, the reinforcement 33 can also be used to realize the assembly of the first magnet 60 on the shell belt 30. Specifically, the first magnet 60 can be fixed on the reinforcement 33, and the reinforcement 33 can be fixed to the end of the connecting end 31, so that the first magnet 60 is fixedly assembled on the end of the connecting end 31 of the shell belt 30, which facilitates the assembly of the first magnet 60 and the shell belt 30.

[0141] To facilitate the magnetic attraction between the first magnet 60 and the second magnet 70, the second magnet 70 can be located in the plug-in slot 412. When the reinforcement member 33 is pluggable and arranged on the plug-in slot 412, it is easier to achieve the mutual attraction between the first magnet 60 and the second magnet 70, thereby realizing the connection between the shell belt 30 and the first assembly part 41.

[0142] For example, the reinforcement member can be fixed on the end of the connection end by snapping. Figure 6 As shown, a first clamp arm 331 and a second clamp arm 332 may be formed on the reinforcement member 33, and a groove 33a may be formed between the first clamp arm 331 and the second clamp arm 332. The end of the connecting end 31 may be inserted into the groove 33a, and the first clamp arm 331 and the second clamp arm 332 may be respectively fixed to two opposite surfaces on the end of the connecting end 31, such as being respectively fixed to two surfaces on the connecting end 31 along the thickness direction of the shell belt, thereby fixing the reinforcement member 33 to the shell belt 30.

[0143] The first magnet 60 may be located in the slot 33a (see Figure 7 As shown), and fixed on the first clamp arm 331 and / or the second clamp arm 332. For example, in combination Figure 5 and Figure 6 As shown, the first magnet 60 can be located on the side of the reinforcement 33 facing the shell band 30, and an avoidance groove 34 can be formed on the end of the connecting end 31 of the shell band 30. When the reinforcement 33 is snap-fitted and fixed on the connecting end 31, the first magnet 60 can be located in the avoidance groove 34, which is beneficial to improving the integration of the various structural components on the connecting end 31, helping to reduce the volume size of the connecting end and improve the aesthetics.

[0144] A positioning groove may be provided on one of the reinforcement member 33 and the insertion groove 412, and a positioning protrusion may be provided on the other one to be plugged into and matched with the positioning groove. When the reinforcement member 33 is plugged into the insertion groove 412, the positioning protrusion may be inserted into the positioning groove. The cooperation between the positioning protrusion and the positioning groove can play a good guiding and positioning role, so that the connection end 31 can be accurately inserted into the insertion groove 412, and the first magnet and the second magnet can be accurately aligned and maintain a strong attraction, so as to realize the rapid and accurate assembly of the shell belt 30, and help to improve the convenience of the protective shell.

[0145] Figure 7 A schematic diagram of the assembly of a reinforcement member and a first magnet in a protective shell provided in an embodiment of the present application.

[0146] For example, combined with Figure 6 and Figure 7 As shown, a positioning groove 333 may be formed on one end of the reinforcement member 33 facing away from the shell belt 30 , and the positioning groove 333 may penetrate the reinforcement member 33 along the thickness direction of the shell belt 30 .

[0147] Figure 8 A schematic structural diagram of a first assembly provided in an embodiment of the present application.

[0148] Combination Figure 8 As shown, a positioning protrusion 413 can be formed in the plug-in groove 412 of the first assembly part 41. When the reinforcement on the connecting end is plugged into the plug-in groove, the positioning groove and the positioning protrusion can be plugged into and matched with each other. The positioning groove and the positioning protrusion play a guiding and positioning role, so that the connecting end can be quickly and smoothly connected to the first assembly part.

[0149] It can be understood that in order to ensure the connection strength between the first assembly part and the reinforcement of the shell belt, under the condition of ensuring the detachable connection between the shell belt and the first assembly part, an interference fit can be achieved between the positioning protrusion and the positioning groove. For example, the opening size of the positioning groove can be slightly smaller than the outer circumferential size of the positioning protrusion, so that the positioning protrusion and the positioning groove are clamped together by interference fit.

[0150] Among them, continue to see Figure 8 As shown, a receiving groove 414 may be provided on the positioning protrusion 413 , and the second magnet 70 may be fixed in the receiving groove 414 , so as to improve the integration of the entire first assembly part 41 and reduce the volume size of the first assembly part 41 .

[0151] Accordingly, the first magnet 60 may be located opposite to the positioning slot 333 (see Figure 6 and Figure 7As shown), the first magnet can be located on the side of the bottom of the positioning groove facing the shell belt. When the positioning groove is plugged into the positioning protrusion, the bottom of the positioning groove can abut against the end face of the positioning protrusion facing the positioning groove. The first magnet and the second magnet can be better attracted and connected, which is beneficial to improve the connection strength between the shell belt and the first assembly part, and improve the stability of the protective shell.

[0152] See also Figure 7 As shown, a clearance opening 3331 may be provided on the bottom of the positioning groove 333, so that a portion of the first magnet 60 may extend to the clearance opening 3331. Figure 8 As shown, part of the second magnet 70 can extend to the notch of the receiving groove 414. When the positioning groove is plugged into the positioning protrusion, the first magnet and the second magnet can contact and attract each other, further improving the connection strength between the first magnet and the second magnet.

[0153] The detachable connection between the second assembly part and the housing is described below.

[0154] Fig. 9 for Figure 1 An enlarged view of the local structure of the cross section formed along the BB surface.

[0155] There are also various ways of detachably connecting the second assembly part and the housing, for example, see Fig. 9 As shown, in one example, the second assembly part 42 and the housing 110 can be detachably connected by threaded engagement.

[0156] Exemplarily, the assembly component may further include a fastener 430, which may have an external thread, for example, the fastener 430 may be a screw, etc. A threaded hole (not shown in the figure) may be provided on the second assembly part 42, the first end of the fastener 430 may abut against the housing 110, the second end of the fastener 430 may pass through the housing 110, and the external thread on the second end of the fastener 430 may be threadedly matched with the threaded hole on the second assembly part 42, so that the second assembly part 42 and the housing 110 are fixed by the fastener 430.

[0157] When the second assembly part 42 needs to be removed, the fastener 430 or the second assembly part 42 can be rotated to make the fastener 430 and the second assembly part 42 rotate relative to each other. The second assembly part 42 rotates along the external thread of the second end of the fastener 430 and the two will slide relative to each other, so that the second assembly part 42 can be separated from the fastener 430, and the second assembly part 42 and the fastener 430 can be removed from the shell 110.

[0158] For example, taking the case where both ends of the second assembly member 42 are detachably connected to the housing 10 by fasteners 430, see Fig. 9As shown, the two fasteners 430 are fastener 43 and fastener 44 respectively. A first threaded hole (not shown in the figure) may be formed on one end of the second assembly part 42, and a second threaded hole (not shown in the figure) may be formed on the other end of the second assembly part 42. The first end 43a of the fastener 43 may abut on the side of the housing 10 facing away from the second assembly part 42, and the second end 43b of the fastener 43 may have an external thread (not shown in the figure). The second end 43b of the fastener 43 may pass through the housing 10 and cooperate with the first threaded hole on one end of the second assembly part 42. The first end 44a of the fastener 44 may abut on the side of the housing 10 facing away from the second assembly part 42, and the second end 44b of the fastener 44 may have an external thread (not shown in the figure). The second end 44b of the fastener 44 may pass through the housing 10 and cooperate with the second threaded hole on the other end of the second assembly part 42, so as to fix the second assembly part 42 to the housing 10.

[0159] Fig.10 A schematic diagram of the structure of the second assembly part and the shell body in a protective shell provided in an embodiment of the present application being disassembled.

[0160] When the second assembly part 42 needs to be disassembled, the first end of the fastener 43 can be rotated to Fig.10 As shown, the fastener 43 and the second assembly part 42 are rotated and slid relative to each other, and the second end of the fastener 43 is separated from one end of the second assembly part 42. Correspondingly, the first end of the fastener 44 is rotated to separate the second end of the fastener 44 from the other end of the second assembly part 42, thereby removing the second assembly part 42 (assembly component) from the housing 10.

[0161] It is understandable that auxiliary grooves may be formed on the end surfaces of the first ends of the fasteners 43 and 44, respectively, and the user may insert a tool, such as a screwdriver, into the auxiliary grooves to facilitate the rotation of the fasteners 43 and 44. That is, the disassembly of the second assembly part 42 may be achieved with the help of a tool.

[0162] To further improve convenience, the second assembly part 42 can also be disassembled without the aid of tools.

[0163] Fig.11 An enlarged view of the local structure of a second assembly part in another protective shell provided in an embodiment of the present application.

[0164] See also Fig.11As shown, the second assembly part 42 may include a mounting component 421 and a locking component 422, the locking component 422 is used to cooperate with the mounting component 421, the mounting component 421 can be detachably connected to the housing 10, and the mounting component 421 can be assembled to the housing 10, so that the entire second assembly part 42 is fixedly assembled to the housing 10. The mounting component 421 can also be removed from the housing 10, so that the second assembly part 42 is removed from the housing, and the entire assembly component is removed from the housing.

[0165] The locking component 422 can be detachably connected to the mounting assembly 421 , and the locking component 422 can play a role in locking and unlocking the assembly and disassembly between the mounting assembly 421 and the housing 10 .

[0166] The second assembly member 42 can have two states, such as a locked state and an unlocked state. Fig.11 As shown, when the second assembly part 42 is in a locked state, the locking component 422 is connected to the mounting component 421, and the locking component 422 and the mounting component 421 are fixed in cooperation so that when an external force is directly applied to the mounting component 421, the mounting component 421 and the shell 10 cannot move relative to each other, and the mounting component 421 is fixed on the shell 10.

[0167] When the second assembly part 42 is in the unlocked state, the locking component 422 is separated from the mounting component 421, and the mounting component 421 can move relative to the housing 10. By applying external force to the mounting component 421, it can be moved relative to the housing 10 and separated from the housing 10, and the mounting component 421 is removed from the housing, thereby realizing the disassembly of the entire second assembly part 42 from the housing 10. In other words, the locking or unlocking of the locking component 422 can satisfy the stable connection between the mounting component 421 and the housing 10, and can also satisfy the disassembly of the mounting component 421 and the housing 10, and in the unlocked state, directly acting on the mounting component 421 to make it move relative to the housing 10 can realize the overall disassembly of the second assembly part 42, which is conducive to the installation and disassembly of the second assembly part 42 without the assistance of tools.

[0168] Specifically, the mounting assembly 421 may include two mounting members 4210, and the first ends of the two mounting members 4210 may be detachably connected to the housing 110, respectively, so as to achieve detachable cooperation between the mounting assembly 421 and the housing 10. Fig.11As shown, the two mounting members 4210 can be mounting members 4211 and mounting members 4212, respectively. The mounting members 4211 and mounting members 4212 can be located on both sides of the entire second assembly member 42. The first end of the mounting member 4211 and the first end of the mounting member 4212 can be respectively used as the two ends of the second assembly member 42. The first end of the mounting member 4211 and the first end of the mounting member 4212 can be respectively connected to the housing 10 by the fasteners described above. For example, the mounting member 4211 can be threadedly matched with the fastener 43 (refer to Fig.13 As shown), the mounting member 4212 can cooperate with the thread of the fastener 44. Rotating the mounting member 4211 can make the mounting member 4211 relatively separated from the fastener 43, and rotating the mounting member 4212 can also separate it from the fastener 44.

[0169] The two ends of the locking component 422 can be detachably connected to the second end of the mounting member 4211 and the second end of the mounting member 4212, respectively, so as to realize the detachable cooperation between the locking component 422 and the mounting assembly 421. Fig.11 As shown, the second assembly part 42 is in a locked state, and the two ends of the locking part 422 are respectively connected to the mounting part 4211 and the mounting part 4212. At this time, the second assembly part 42 can be a U-shaped frame, which has high aesthetics and is conducive to the sleeve assembly between the second assembly part 42 and the first assembly part 41. The first assembly part 41 can be directly sleeved on the second assembly part 42 from one end of the second assembly part 42. The first assembly part 41, the second assembly part 42 and the shell 10 can be formed separately and then assembled together, so that the assembly of the entire protective shell has good flexibility and is easy to produce.

[0170] Correspondingly, when the two ends of the locking component 422 are respectively detached from the mounting member 4211 and the mounting member 4212 , the second assembly member 42 is in an unlocked state.

[0171] It can be understood that when the second assembly part 42 is disassembled and separated from the shell 10, the first assembly part 41 can also be disassembled and separated from the second assembly part 42, so that the first assembly part 41 or the second assembly part 42 can be replaced separately. When one is damaged separately, there is no need to replace the entire assembly component or protective shell, which helps to reduce replacement and maintenance costs and further enhance user experience.

[0172] The locking member 422 may include a first stopper 4221, and two ends of the first stopper 4221 may be pluggable with the second end of the mounting member 4211 and the second end of the mounting member 4212, respectively. Fig.11As shown, the first stopper 4221 can be plugged into the second end of the mounting member 4211 and the second end of the mounting member 4212, so that the two ends of the locking member 422 are respectively connected to the two mounting members, thus achieving the fixation of the locking member 422 and the mounting assembly 421, and making the second assembly member 42 in a locked state. At this time, since the locking member 422 connects and fixes the two mounting members 4210, when the locking member 422 directly acts on the mounting member 4210, the two mounting members cannot rotate relative to the housing 10 (or the fastener), so that the mounting assembly 421 is fixedly assembled to the housing 10, and the second assembly member 42 is fixed to the housing 10.

[0173] Fig.12 This is a schematic diagram of the split structure of the locking component and the mounting assembly in another protective shell provided in an embodiment of the present application. Fig.13 A schematic diagram of the disassembled structure of a locking component, a mounting assembly and a shell in another protective shell provided in an embodiment of the present application.

[0174] See also Fig.12 As shown, the first stopper 4221 can also be pulled out from the first end of the mounting member 4211 and the first end of the mounting member 4212, so that the locking member 422 is disassembled and separated from the mounting assembly 421, and the second assembly member 42 is in an unlocked state. At this time, the mounting member 4211 and the mounting member 4212 have a degree of freedom of movement, so that the mounting member 4211 and the mounting member 4212 can move relative to the housing 10. For example, by applying force to rotate the mounting member 4211, the mounting member 4211 can rotate relative to the fastener 43, and the mounting member 4211 can slide relatively along the second end of the fastener 43, and the mounting member 4211 can slide relative to the fastener 43. Fig.13 As shown, the mounting member 4211 can be separated from the fastener 43.

[0175] Correspondingly, force is applied to rotate the mounting member 4212, so that the mounting member 4212 can rotate relative to the fastener 44, and the mounting member 4211 slides relatively along the second end of the fastener 43, so that the mounting member 4212 is separated from the fastener 44. The mounting member 4211, the mounting member 4212, the fastener 43 and the fastener 44 can all be removed from the shell 10, and the second assembly member 42 and the entire assembly component are removed from the shell 10. In other words, the second assembly member 42 is unlocked by pulling out and separating the locking member 422 from the mounting component 421, and the second assembly member 42 can be disassembled by rotating the two mounting members 4210 protruding from the shell 10 respectively, and the second assembly member 42 can be disassembled and installed without the aid of tools, that is, the entire assembly component and the shell belt can be disassembled and installed without the aid of tools, which is more convenient and quick, and significantly improves the convenience of the protective shell.

[0176] Continue to see Fig.13As shown, in order to achieve the plug-in cooperation between the first limiting member 4221 and the mounting member 4210 , both ends of the first limiting member 4221 may respectively have a plug-in portion 4220 , and the two mounting members 4210 may respectively have a guide rail portion 4201 that can cooperate with the plug-in portion 4220 .

[0177] For example, the plug-in portions 4220 at both ends of the first limiting member 4221 are respectively plug-in portions 4221a and plug-in portions 4221b, and the guide rail portions 4201 on the two mounting members 4210 are respectively guide rail portions 4211a and guide rail portions 4212a. If the mounting member 4211 has a guide rail portion 4211a and the mounting member 4212 has a guide rail portion 4212a, the plug-in portion 4220 can slide along the guide rail portion 4201, so that the plug-in portions 4221a and the plug-in portions 4221b can be respectively plugged and fixed on the guide rail portions 4211a and the guide rail portions 4212a, and the plug-in portions 4221a and the plug-in portions 4221b can also be respectively pulled out from the guide rail portions 4211a and the guide rail portions 4212a and removed.

[0178] The guide rail portion 4201 may include a starting end and a tail end. For example, taking the guide rail portion 4211a and the plug-in portion 4221a as an example, see Fig.13 As shown, the guide rail portion 4211a may include a starting end 4211a1 and a tail end 4211a2, and the direction from the starting end 4211a1 to the tail end 4211a2 may be the extension direction of the guide rail portion 4211a, and the extension direction may be perpendicular to the back shell of the housing 10, that is, may be parallel to the thickness z direction of the housing 10. The plug-in portion 4221a may be inserted from the starting end 4211a1 of the guide rail portion 4211a and arranged on the guide rail portion 4211a, or the plug-in portion 4221a may also be pulled out from the guide rail portion 4211a from the starting end 4211a1 of the guide rail portion 4211a. For example, taking the guide rail portion 4211a as a groove portion and the plug-in portion 4221a as a protrusion as an example, the starting end 4211a1 may be an open end of the groove portion, and the protrusion passes through the open end and is inserted into the groove portion, and the protrusion may also pass through the open end and slide out of the groove portion and be removed.

[0179] The starting end 4211a1 of the guide rail portion 4211a may be located on the end surface of the mounting member 4211 facing away from the housing 10, as shown in FIG. Fig.13As shown, the plug-in portion 4221a can pass through the starting end 4211a1 and move toward the shell body 10, so as to be inserted into the guide rail portion 4211a. The plug-in portion 4221a can also pass through the starting end 4211a1 and move in the direction away from the shell body 10, so as to be pulled out and removed from the guide rail portion 4211a, thereby realizing the installation and disassembly of the first limiting member 4221 and the mounting member 4211, and can avoid the shell body 10 from affecting the plugging and unplugging of the first limiting member 4221, facilitate the plugging and unplugging of the first limiting member 4221 and the mounting component 421, and facilitate the installation and disassembly of the second assembly member.

[0180] The guide rail portion 4201 may be a groove portion located on the mounting member 4210, and the plug-in portion 4220 may be a protrusion portion located on the first position-limiting member 4221, or the guide rail portion 4201 may be a protrusion portion located on the mounting member 4210, and the plug-in portion 4220 may be a groove portion located on the first position-limiting member 4221. The first position-limiting member 4221 and the mounting member 4210 can be pluggable by the groove portion and the protrusion portion, and the groove portion and the protrusion portion cooperate with each other to play a limiting role. For example, taking the extension direction of the guide rail portion being parallel to the thickness direction as an example, the cooperation between the groove portion and the protrusion portion can limit the movement of the first position-limiting member 4221 in the width direction and the length direction (combined with Fig.11 As shown), during use, the first limit member will not fall off from the mounting assembly 421 even if it is subjected to forces along the width x direction and the length y direction, thereby improving the connection stability between the locking member 422 and the mounting assembly 421, thereby improving the reliability of the entire assembly assembly.

[0181] It is understandable that during use, when the side of the first limit member 4221 facing the shell 10 is subjected to an upward force in the thickness direction, the first limit member 4221 is prone to the risk of detaching from the installation component 421, affecting the reliability of the assembly component.

[0182] Fig.14 This is an enlarged view of the local structure of a second assembly part in a protective shell provided in an embodiment of the present application.

[0183] Therefore, in order to further improve the matching stability between the locking component 422 and the mounting assembly 421, see Fig.14 As shown, the locking component 422 may also include a second limiting member 4222, which may be detachably connected to the first limiting member 4221, that is, the first limiting member 4221 and the second limiting member 4222 may be fixedly cooperated with each other, and the first limiting member 4221 and the second limiting member 4222 may also be detachably separated from each other.

[0184] Continue to see Fig.14As shown, the second assembly part 42 is in a locked state, the two ends of the first stopper 4221 are respectively inserted into the mounting part 4211 and the mounting part 4212, the first stopper 4221 is connected to the second stopper 4222, and the two ends of the second stopper 4222 are respectively abutted against the side of the mounting part 4211 and the mounting part 4212 facing the housing 10. The first stopper 4221 can be limited by the second stopper 4222, and the force that pushes upward (backwards from the housing 10) along the thickness z direction during use will act on the second stopper 4222. Since the two ends of the second stopper 4222 are respectively abutted against the side of the mounting part 4211 and the mounting part 4212 facing the housing 10, the second stopper 4222 and the first stopper 4221 will not fall out of the mounting assembly 421, further improving the fastness between the locking part 422 and the mounting assembly 421, and improving the assembly stability of the second assembly part and the entire assembly assembly.

[0185] Fig.15 A schematic diagram of the disassembled structure of a locking component and an installation component in a protective shell provided in an embodiment of the present application, Fig.16 A schematic diagram of the disassembled structure of a locking component, a mounting assembly and a shell in a protective shell provided in an embodiment of the present application.

[0186] See also Fig.15 As shown, the second stopper 4222 can also be disassembled and separated from the first stopper 4221, and the first stopper 4221 can be removed from the mounting member 4211 and the mounting member 4212. The second stopper 4222 can also be removed without abutting against the mounting member 4211 and the mounting member 4212, so that the locking member 422 is disassembled and separated from the mounting assembly 421, and the second assembly member 42 is in an unlocked state. The mounting member 4211 and the mounting member 4212 have a degree of freedom of movement, so that the mounting member 4211 and the mounting member 4212 can move relative to the housing, for example, rotating the mounting member 4211, combined with Fig.16 As shown, the mounting member 4211 can rotate and slide relative to the fastener 43, so that the mounting member 4211 is separated from the fastener 43. The mounting member 4212 is rotated so that the mounting member 4212 can rotate and slide relative to the fastener 44, so that the mounting member 4212 is separated from the fastener 44, thereby removing the fastener 43, the fastener 44, the mounting member 4211, and the mounting member 4212 from the housing 10, and the entire second assembly member and the assembly component are removed from the housing 10.

[0187] Fig.17 This is a schematic diagram of a disassembled structure of a second assembly in a protective shell provided in an embodiment of the present application. Fig.18 for Figure 1 A front view of a cross section formed along plane BB in FIG.

[0188] Among them, combined Fig.17and Fig.18 As shown, a positioning groove 4202 can be formed on the mounting member 4210, and the positioning groove 4202 can be located on the side of the mounting member 4210 facing the shell. For example, the mounting member 4211 has a positioning groove 4211b on the side facing the shell (the second limiting member 4222), and the mounting member 4212 has a positioning groove 4212b on the side facing the shell (the second limiting member 4222).

[0189] When the second assembly part 42 is in the locked state, the two ends of the second position-limiting member 4222 can be respectively located in the positioning groove 4211b and the positioning groove 4212b, and abut against the groove bottoms of the two positioning grooves 4201. The positioning groove 4202 can play a guiding and limiting role, so that the second position-limiting member 4222 can be conveniently and quickly assembled to the installation component 421, thereby facilitating the convenient and rapid assembly of the second assembly part 42.

[0190] Continue to see Fig.17 As shown, the mounting member 4210 may further include an abutment portion 4203, which may be located at the rear end of the guide rail portion. For example, the mounting member 4211 may include an abutment portion 4211c, which may be located at the rear end 4211a2 of the guide rail portion 4211a. Fig.18 As shown, the mounting member 4212 is also formed with abutment portion 4212c (see Fig.18 As shown), the abutment portion 4212c is located at the rear end of the guide rail portion 4212a.

[0191] When the second assembly member 42 is in the locked state, the Fig.17 and Fig.18 As shown, the plug-in portion 4221a and the plug-in portion 4221b of the first limiting member 4221 are respectively plugged into the guide rail portion 4211a of the mounting member 4211 and the guide rail portion 4212a of the mounting member 4212, the plug-in portion 4221a abuts against the side of the abutting portion 4211c facing the starting end of the guide rail portion 4211a, and the plug-in portion 4221b abuts against the side of the abutting portion 4212c facing the starting end of the guide rail portion 4212a, and the abutting portion 4211c and the abutting portion 4212c respectively play a further limiting role on the first limiting member 4221, so that the first limiting member 4221 will not fall out of the mounting member 4211 and the mounting member 4212 when subjected to a force downward in the thickness z direction (toward the shell 10) during use, which is beneficial to further improve the firmness between the locking component 422 and the mounting assembly 421.

[0192] The first limiting member 4221 and the second limiting member 4222 may be detachably connected in various ways. For example, the first limiting member 4221 and the second limiting member 4222 may be detachably connected by means of a snap connection, a magnetic fit connection, or the like.

[0193] Exemplary, continue to combine Fig.17 and Fig.18 As shown, the protective shell may further include a third magnet 80 and a fourth magnet 90. The third magnet 80 may be fixed on the first limiting member 4221. For example, a receiving groove may be formed on the surface of the first limiting member 4221 facing the second limiting member 4222, and the third magnet 80 may be fixed in the receiving groove.

[0194] The fourth magnet 90 can be fixed on the second stopper 4222, see Fig.18 As shown, when the second assembly part 42 is in a locked state, the second limiting member 4222 can abut against the positioning groove, and the first limiting member 4221 and the second limiting member 4222 can be attracted to each other through the third magnet 80 and the fourth magnet 90, so that the first limiting member 4221 and the second limiting member 4222 are connected.

[0195] When the first stopper 4221 is pulled off the mounting member, the applied force is greater than the attraction force of the third magnet 80 and the fourth magnet 90, so that the first stopper 4221 and the second stopper 4222 can be separated, and the first stopper 4221 and the second stopper 4222 can be removed from the mounting assembly 421. The installation and removal of the first stopper 4221 and the second stopper 4222 are more convenient and quick, and are easy to implement without the aid of any tools.

[0196] It should be noted that when the first limit member 4221 and the second limit member 4222 are connected, the fourth magnet 90 can also be accommodated in the accommodation groove of the first limit member 4221, which is beneficial to improve the integration of the entire second assembly in the locked state, help to improve the aesthetics and reduce the volume size.

[0197] Fig.19 A schematic diagram of the inner surface structure of a shell in a protective shell provided in an embodiment of the present application.

[0198] In this example, see Fig.19 As shown, in order to facilitate the fastener 430 to abut against the housing 110, an abutment groove 103 may be provided on the housing 110. Specifically, the abutment groove 103 is located on the side of the housing 110 facing away from the assembly component. The first end of the fastener 430 may abut against the abutment groove 103, and the second end of the fastener 430 may pass through the housing 110 to connect with the second assembly part. For example, taking the fastener 43 as an example, when the second assembly part is in a locked state, the first end 43a of the fastener 43 may abut against the bottom of the abutment groove 103, and the second end of the fastener 43 passes through the abutment groove 103 and connects with the second assembly part (refer to Fig.18The abutment groove 103 can limit the first end of the fastener 430. The first end of the fastener 430 is accommodated in the abutment groove 103, which can prevent the first end of the fastener 430 from protruding in the accommodation cavity of the housing 110 and causing damage to the electronic device. The abutment groove 103 can also facilitate the positioning and assembly of the fastener 430, which is conducive to improving the assembly efficiency.

[0199] The shape of the abutting groove 103 may match the shape of the first end of the fastener 430 . For example, the shape of the first end 43 a of the fastener 43 may be circular, and the shape of the abutting groove 103 may also be circular.

[0200] It can be understood that when the first end of the fastener 430 and the abutment groove 103 are both circular in shape, and the second end of the fastener 430 is rotationally connected to the second assembly part by threaded cooperation or the like, when the second assembly part is in an unlocked state, when the movable mounting part is rotated, it is necessary to manually keep the fastener 430 fixed, thereby achieving disassembly of the second assembly part.

[0201] Therefore, in another example, a limiting protrusion can be formed on one of the outer peripheral side wall of the first end of the fastener 430 and the inner peripheral side wall of the abutment groove 103, and a limiting groove can be formed on the other one, and the limiting protrusion can be inserted and removed in the limiting groove. When the first end of the fastener 430 abuts in the abutment groove 103, the limiting protrusion is inserted into the limiting groove, and the cooperation of the limiting protrusion and the limiting groove can fix the fastener 430 and the housing 110, so that the fastener 430 and the housing will not rotate relative to each other, and then when the mounting part is rotated, the fastener 430 and the housing 110 remain relatively fixed, and there is no need to manually achieve fixation, which is more conducive to the convenient disassembly of the second assembly part and improves the user experience.

[0202] The limiting protrusion on the first end of the fastener 430 can also be pulled out from the limiting groove, thereby meeting the separation requirement of the fastener 430 and the shell 110 and realizing the disassembly and separation of the fastener 430 and the shell 110.

[0203] Fig. 20 A schematic diagram of the inner surface structure of a shell in another protective shell provided in an embodiment of the present application.

[0204] For example, see Fig. 20As shown, a plurality of limiting protrusions 431 may be formed on the side wall of the first end 43a of the fastener, and the plurality of limiting protrusions 431 may be distributed on the outer periphery of the first end 43a, such as the shape of the first end 43a of the fastener may be a triangle, and the three corners of the triangle may be the limiting protrusions 431 formed on the first end 43a of the fastener. Correspondingly, a plurality of limiting grooves 103a may be formed on the side wall of the abutting groove 103 of the shell, and the plurality of limiting grooves 103a may be distributed on the inner periphery of the abutting groove 103, and respectively correspond to the plurality of limiting protrusions 431, such as the shape of the limiting groove 103a may also be a triangle, and the three corners of the triangle may be the limiting grooves 103a formed on the abutting groove 103, when the first end 43a of the fastener abuts on the abutting groove 103, the limiting protrusions 431 are correspondingly located in the limiting grooves 103a, so that the first end 43a of the fastener and the shell 110 cannot rotate relative to each other.

[0205] Of course, in some other examples, the shape of the first end of the fastener 430 may also be other types of polygons, and accordingly, the shape of the abutment groove 103 may also be other types of polygons, and limiting protrusions or limiting grooves may be formed at the corners of the polygon.

[0207] For example, see Fig.21 As shown, the shape of the first end 43a of the fastener 43 can also be a hexagon, and the six corners of the hexagon can respectively be the limiting protrusions 431 formed on the first end 43a of the fastener, and the shape of the abutment groove 103 can also be a hexagon, and the six corners of the hexagon can respectively be the limiting grooves 103a formed on the abutment groove 103.

[0208] Alternatively, in some other examples, the second assembly part and the shell can also be connected in other detachable ways, for example, the second assembly part and the shell can also be detachably connected by snap-fitting. Exemplarily, the assembly component can also include a snap-fitting part, one end of which can abut against a surface of the shell facing away from the second assembly part, and the other end of the snap-fitting part can have a first snap-fitting part, for example, a protrusion, a groove, etc., and the second assembly part can have an elastic clamping arm, and the elastic clamping arm can be formed with a second snap-fitting part for snap-fitting with the first snap-fitting part, for example, a groove, a protrusion, etc. When the second assembly part needs to be assembled, one end of the clamping part is abutted against the shell, and the other end of the clamping part passes through the shell, and the first snap-fitting part on the other end of the clamping part snap-fits with the second snap-fitting part on the elastic clamping arm of the second assembly part, so that the second assembly part is assembled with the shell.

[0209] When the second assembly part needs to be disassembled, force can be applied to deform the elastic clamp arm, thereby separating the second clamping part and the first clamping part, and separating the second assembly part from the clamping part, and the clamping part can be separated from the shell, so that the second assembly part and the clamping part can be removed from the shell respectively.
