Description

Technical Field

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

[0002] With the development of modern technology, electronic devices such as smartphones have become an indispensable part of people's daily lives. Users are increasingly inclined to use their mobile phones to watch videos, make video calls, and perform other activities that require the device to be upright. In order to meet this demand, various types of mobile phone stand protective cases have appeared on the market. These protective cases not only provide basic protection functions, but also can stand up the phone so that users can operate it without hands.

[0003] At present, most mobile phone holder protective cases on the market often require two-handed operation to stand them up when in use. This design is extremely inconvenient in many scenarios. For example, when dining, users cannot easily unfold the stand. In addition, many existing stand protective cases adopt a complex hinge design, which not only increases the difficulty of unfolding the stand, but may also affect the overall structural strength and durability of the protective case. In summary, the existing mobile phone holder protective cases have the following main problems: Inconvenient two-handed operation: When users need to stand up the device, they usually need to use both hands to unfold the stand. This is extremely inconvenient in certain specific scenarios (such as holding objects in one hand, dining, or other situations where both hands cannot be freed). The operation steps are cumbersome: traditional stands require users to manually unfold and adjust the angle. There are many operation steps, which are not fast enough, affecting the efficiency of use. Utility Model Content

[0004] The present application provides a protective case and an electronic device, wherein the protective case is used to solve the problem that it is inconvenient to open a bracket of an existing protective case.

[0005] To achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, a protective case is provided for an electronic device, the protective case comprising: a shell, the shell being used to cover the electronic device body; a support portion, the support portion being mounted on the shell and being able to be extended outside the shell; a thrust portion, the thrust portion being mounted between the support portion and the shell and being used to provide a thrust to the support portion so that the support portion is extended outside the shell; and a control portion, the control portion being mounted on the shell and having a locking state capable of limiting the extension of the support portion, and an unlocking state capable of avoiding the unextended support portion.

[0007] The protective case provided in the embodiment of the present application is different from the traditional mobile phone holder. The support part can be automatically unfolded when needed through the cooperation of the control part and the thrust part, avoiding the tedious manual operation. In the locked state, the control part can limit the expenditure of the support part to prevent it from accidentally unfolding when not in use. Not only does it improve the overall stability of the protective case, but it also avoids equipment damage or inconvenience caused by accidental unfolding of the bracket. When the bracket needs to be used, the control part can be switched to an unlocked state, so that the support part can be smoothly unfolded under the action of the thrust part to provide a support function. The protective case of the embodiment of the present application is particularly suitable for use in a one-handed operation environment. The user only needs to press lightly, and the support part will automatically unfold to provide stable support.

[0008] In one embodiment, the first end of the support portion is rotatably mounted on the housing, and the second end of the support portion can be extended out of the housing. The first end of the support portion is mounted on the housing and has a rotatable characteristic, and the second end of the support portion can be automatically extended out of the housing, so that when the user needs to use the support function, there is no need for two-handed operation or complicated adjustment steps. Only a simple unlocking action is required, and the support portion can automatically unfold to a suitable angle to provide stable support.

[0009] In one embodiment, the thrust part includes an elastic structure, which is installed between the support part and the shell, and is used to provide an elastic thrust to the support part so that the support part is extended out of the shell. The elastic structure can ensure that the support part maintains a stable and firm support state during the deployment process, is not easily affected by external interference or movement, and improves the stability and safety of the device when in use.

[0010] In one embodiment, the control part includes a limiting part, which is movably mounted on the shell. When the control part is in a locked state, the limiting part cooperates with the supporting part to limit the extension of the supporting part; when the control part is in an unlocked state, the limiting part avoids the unextended supporting part.

[0011] In one embodiment, the limiting part is located between the shell and the support part, and the limiting part includes a transmission body and a first limiting structure located on the transmission body, the first limiting structure is located on a side of the transmission body close to the support part, and a second limiting structure is provided on a side of the support part close to the shell, and when the control part is in a locked state, the first limiting structure cooperates with the second limiting structure to limit the expenditure of the support part. The setting of the transmission body enables the control part to be controlled at a position far away from the support part, which provides a more convenient operation experience for the user. The user can easily control the expansion and folding of the support part without being too close to the support part, which enhances the convenience of use and operational flexibility of the product.

[0012] In one embodiment, the transmission body includes a transmission section, a limiting section located at a first end of the transmission section, a first limiting structure is arranged on the limiting section, a guide channel is arranged on the housing, and the transmission section is movably arranged in the guide channel along the extension direction of the guide channel. The transmission section is movably arranged along the guide channel on the housing, ensuring that the control unit can still accurately control the transmission body at a remote position, thereby avoiding accidental damage or instability caused by misoperation or external interference.

[0013] In one embodiment, the transmission body further includes a control section at the second end of the transmission section, the first limiting structure includes a first buckle, the first buckle faces the control section, the second limiting structure includes a second buckle for cooperating with the first buckle, and the transmission section moves toward its first end, so that the first buckle can avoid the second buckle, wherein the first end of the transmission section is arranged opposite to the second end of the transmission section. When the transmission section moves toward its first end, the first buckle can avoid the second buckle. This ensures that the support portion can be smoothly unfolded when it needs to be unfolded, and can be firmly locked when not in use to prevent accidental unfolding.

[0014] In one embodiment, the control unit further includes a reset unit, which is located between the control section and the housing and is used to reset the control unit from an unlocked state to a locked state. The reset unit is configured so that the control unit can automatically reset from an unlocked state to a locked state after the user operation is completed. The user does not need to perform additional manual operations to reset the reset unit, which simplifies the operation steps and improves the convenience of use.

[0015] In one embodiment, a housing is provided with a housing cavity, the housing cavity is communicated with the guide channel, the control section is movably installed in the housing cavity, and the reset portion includes a spring, the first end of the spring abuts against the inner wall of the housing cavity on the side close to the guide channel, and the second end of the spring abuts between the side walls of the control section on the side close to the guide channel. The setting of the spring enables the control section to automatically reset to the locked state after being in the unlocked state. The spring applies an appropriate reaction force in the housing cavity to ensure that the control section automatically returns to the locked position after the user operation is completed, without the need for additional manual intervention.

[0016] In one embodiment, a first guide slope is provided on a side of the first buckle away from the housing, and a second guide slope is provided on a side of the second buckle close to the housing, and the first buckle can be moved in a direction away from the second buckle by guiding the first guide slope and the second guide slope. Through the cooperation of the first guide slope and the second guide slope, when the user presses the support portion back to the unextended position, the two slopes can guide each other, so that the first buckle moves in a direction away from the second buckle.

[0017] In one embodiment, a clearance opening is provided in the middle of the second buckle, and the clearance opening is used to make way for the transmission section. The setting of the clearance opening allows the transmission section to obtain enough space for movement when necessary.

[0018] In one embodiment, there are multiple springs, which are arranged on both sides of the transmission section. The multiple springs can work together to ensure that the transmission section can maintain a stable mechanical balance at any position, avoiding the problem of device instability caused by failure or failure of a single spring.

[0019] In one embodiment, the first end of the support portion is pivotally connected to the housing, and the elastic structure includes a torsion spring, which is installed on the pivot axis between the support portion and the housing, and is used to provide an elastic thrust to the support portion so that the support portion is extended out of the housing. Through the elastic thrust provided by the torsion spring, the support portion can be smoothly extended from the inside of the housing to the outside position when needed, and the operation process is smoother and more convenient.

[0020] In one embodiment, the protective shell further includes a flexible layer, which covers the outer side of the housing and the control part and avoids the support part. As an outer covering layer, it can effectively absorb external impact force, protect the internal structure and electronic equipment of the device from damage, and facilitate the user to press the control section. The flexible layer makes the protective shell softer and more comfortable to the touch, and the user feels more comfortable when holding or touching it, is not easy to slip, and does not cause discomfort to the skin.

[0021] In one embodiment, a storage recess is further provided on the outer side of the housing, and the storage recess is used to at least partially accommodate the unextended support part. This optimizes space utilization and protects the support part from accidental damage by the external environment. The support part is effectively surrounded and protected in the storage recess, ensuring its long-term functionality and appearance integrity.

[0022] A second aspect of the present application provides an electronic device, which includes a protective shell and an electronic device body. The protective shell is mounted on the electronic device body, and the protective shell is the above-mentioned protective shell.

[0023] Through the above technical solution, since the electronic device includes the above protective shell, it at least has all the beneficial effects of the protective shell, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] The mobile phone stand protective case in the related art often requires two hands to stand it up when in use. This design is extremely inconvenient in many scenarios. For example, when dining, the user cannot easily unfold the stand. In addition, many existing stand protective cases adopt a complex shaft design, which not only increases the difficulty of unfolding the stand, but also may affect the overall structural strength and durability of the protective case.

[0049] As can be seen from the above, the existing mobile phone stand protective cases have the following main problems: Inconvenient two-handed operation: When users need to stand up the device, they usually need to use both hands to unfold the stand. This is extremely inconvenient in certain specific scenarios (such as holding objects with one hand, dining, or other situations where both hands cannot be free). Cumbersome operation steps: Traditional stands require users to manually unfold and adjust the angle, which has many operation steps and is not fast enough, affecting the efficiency of use.

[0050] See also Figure 1 , Figure 2 and Figure 3As shown, the protective shell in the embodiment of the present application includes a shell 10, a support part 20, a thrust part and a control part 30. The shell 10 is used to set the electronic device body, the support part 20 is installed on the shell 10, and the support part 20 can be extended outside the shell 10. The thrust part is installed between the support part 20 and the shell 10, and is used to provide a thrust to the support part 20 so that the support part 20 is extended outside the shell 10. The control part 30 is installed on the shell 10, and the control part 30 has a locked state that can limit the extension of the support part 20, and an unlocked state that can avoid the unextended support part 20. Among them, the shell 10 is the main structural part of the protective shell, which is used to cover and protect the electronic device body (such as a smart phone). It provides basic protection functions to prevent the device from being physically damaged in daily use, such as scratches, collisions and falls. The support part 20 is a part of the protective shell. When the device needs to be erected, it can be extended from the shell 10 to provide support so that the device can stand firmly on a plane, which is convenient for users to watch videos, make video calls or other operations that require the device to stand up. The thrust part is installed between the support part 20 and the housing 10, and its main function is to provide a driving force so that the support part 20 can be extended from the housing 10. The thrust part can be a spring, a magnet or other mechanical device. The control part 30 is installed on the housing 10 and has two states: a locked state and an unlocked state. In the locked state, the control part 30 limits the extension of the support part 20 to prevent it from accidentally unfolding when not in use. In the unlocked state, the control part 30 allows the support part 20 to be extended from the housing 10 to provide a support function. The control part 30 can be a button, a sliding switch or other control mechanism for easy operation by the user. Initially, the protective shell is in a locked state, and the support part 20 is located inside the housing 10 and is restricted by the control part 30, keeping it compact and safe. When the user needs to use the support part 20, the control part 30 is switched to the unlocked state by a simple unlocking operation, such as pressing or sliding the unlocking button or switch on the control part 30. Once the control part 30 is unlocked, the thrust part begins to provide thrust to the support part 20. This thrust causes the support part 20 to be automatically pushed out of the housing 10 without additional manual operation. The support portion 20 will gradually unfold until it reaches a set support position, providing a stable support function for the device.

[0051] The support part 20 in the embodiment of the present application is installed on the housing 10 and can be deployed from the outside of the housing 10. Unlike the traditional mobile phone holder, the support part 20 in the embodiment of the present application can be automatically deployed when needed through the cooperation of the control part 30 and the thrust part, avoiding the cumbersome manual operation. The automatic deployment function is mainly realized by the thrust part, which is installed between the support part 20 and the housing 10 and can provide sufficient thrust to enable the support part 20 to be deployed outside the housing 10. The control part 30 further enhances the safety and stability of the device. The control part 30 is installed on the housing 10 and has two states: a locked state and an unlocked state. In the locked state, the control part 30 can limit the expenditure of the support part 20 to prevent it from accidentally deploying in a non-use state. This not only improves the overall stability of the protective shell, but also avoids equipment damage or inconvenience caused by the accidental deployment of the bracket. When the bracket needs to be used, the control part 30 can be switched to an unlocked state so that the support part 20 can be smoothly deployed to provide a support function. The protective case in the embodiment of the present application is particularly suitable for use in a one-handed operation environment. The user only needs to press lightly, and the support part 20 will automatically unfold to provide stable support. The protective case in the embodiment of the present application is suitable for various electronic devices, especially smart phones, and can meet diverse usage needs and adapt to the usage habits and scenarios of different users. In general, the protective case in the embodiment of the present application solves the problem that the traditional mobile phone holder requires two-handed operation and is not convenient for one-handed use through the design of automation, convenience and safety, greatly improving the user experience in different usage scenarios.

[0052] It should be noted that the protective shell in the embodiment of the present application is used for electronic devices, wherein the electronic devices mainly refer to smart phones. Smart phones, as a multifunctional and portable electronic device, are widely used in modern life, especially for communication, entertainment and work. The electronic device can also be a tablet computer, and users often need to stand it up in different scenarios to watch videos, make video calls and other operations; e-readers, users may need to stand it up during reading for easy reading; portable game consoles, users may need to stand it up when playing games to get a better visual experience; portable electronic displays, users may need to stand it up for mobile office or multimedia playback and other operations; other portable electronic devices: such as portable speakers, cameras, etc., may also need to be stood up when in use for easy operation or viewing.

[0053] See also Figure 4 and Figure 5As shown, the first end of the support portion 20 in the embodiment of the present application is rotatably mounted on the housing 10, and the second end of the support portion 20 can be extended outside the housing 10. The first end of the support portion 20 is mounted on the housing 10 and has a rotatable characteristic, while the second end of the support portion 20 can be automatically extended outside the housing 10, so that when the user needs to use the support function, there is no need for two-handed operation or complicated adjustment steps. Only a simple unlocking action is required, and the support portion 20 can automatically unfold to a suitable angle to provide stable support. This installation method realizes triangular support, which not only keeps the support portion 20 firm when unfolded, but also effectively prevents accidental unfolding or instability, thereby improving the overall stability and safety of use of the device. In order to ensure that the angle of the support portion 20 after the expenditure is reasonable and stable, a limited position structure is set at the first end of the support portion 20. For example, at the connection between the first end of the support portion 20 and the housing 10, a raised stopper or a groove of a specific shape is provided. When the support portion 20 is extended, this stopper or groove will interact with the corresponding structure on the housing 10 to limit the expenditure angle of the support portion 20. For example, when the support portion 20 is extended to a certain angle, such as 60 degrees, the stopper will hit the edge of the shell 10, preventing it from further expanding, so that the support portion 20 can provide stable support for the device within a limited angle range. The stopper can be a special protrusion or a part of the first end of the support plate.

[0054] In the embodiment of the present application, a friction-enhancing portion may be provided at the second end of the support portion 20 to further improve the stability and functionality of the bracket. Such a friction-enhancing portion may be a structure or material having a friction surface, which can increase the friction between the support portion 20 and the support surface (such as a desktop or other plane), thereby ensuring that the support portion 20 is more stable and firm when supporting the device.

[0055] In one embodiment, a special friction surface, such as a rubber pad, a silicone pad, or a surface with a concave-convex structure, is provided on the second end of the support portion 20 or the support surface of the support portion 20. These surfaces can increase the contact friction with the support surface, prevent the support portion 20 from sliding or moving during use, and improve the stability of the support.

[0056] See also Figure 5 , Figure 6 and Fig. 9As shown, the thrust portion in the embodiment of the present application includes an elastic structure 40, which is installed between the support portion 20 and the shell 10, and is used to provide an elastic thrust to the support portion 20 so that the support portion 20 is extended outside the shell 10. The elastic structure 40 applies an elastic thrust to the support portion 20, so that the support portion 20 can be automatically and smoothly pushed out from the inside of the shell 10 after the user performs an unlocking operation. The automatic deployment function greatly simplifies the user's operating steps, without the need for additional manual adjustment or intervention, thereby improving the convenience and efficiency of use. The elastic structure 40 can ensure that the support portion 20 maintains a stable and firm support state during the deployment process, is not easily affected by external interference or movement, and improves the stability and safety of the device when in use.

[0057] In an embodiment of the present application, the thrust portion may choose to use a magnetic component to realize the automatic deployment of the support portion 20. The magnetic component includes a first magnetic member and a second magnetic member that repel each other, which are respectively installed on the shell 10 and the support portion 20. The magnetic component can automatically push the support portion 20 out of the shell 10 to a preset support position after the user performs an unlocking operation through the repulsive force of the magnetic force. This automated operation greatly simplifies the user's operating process, without the need for additional manual adjustments, and improves the convenience and efficiency of use. The magnetic component has the characteristics of low power consumption and long life, and has no mechanical friction, so it has a longer service life and higher reliability. This enables the protective case to maintain stable operating performance for a long time in daily use.

[0058] In an embodiment of the present application, the first end of the support portion 20 is mounted on the housing 10, and by arranging a damping portion between the support portion 20 and the housing 10, the support portion 20 exhibits a smooth and controlled characteristic during the expenditure process, which brings multiple technical advantages and improved user experience to the protective shell. The damping portion can slow down the movement speed of the support portion 20, ensure that the deployment process is smooth and impact-free, and avoid unstable or too fast deployment caused by sudden push, thereby improving the comfort and safety of use. The damping portion helps to reduce the mechanical impact and stress when the support portion 20 is deployed, effectively reduces the degree of wear of the equipment and the protective shell, and prolongs the service life of the entire system. The damping portion mainly adopts a friction method, and the friction damper achieves a damping effect by increasing the friction between the support portion 20 and the housing 10. The magnitude of the friction force can be adjusted by surface coating, material selection or a specially designed contact surface structure, thereby slowing down the movement speed of the support portion 20. The friction damper is simple and effective, and is suitable for occasions where basic damping control is required.

[0059] Specifically, the first end of the support part 20 is mounted on the shell 10, and the friction force is increased between the support part 20 and the shell 10 by the rubber damping part provided between the pivot axis of the support part 20 and the shell 10, so as to effectively and smoothly control the deployment process of the support part 20. Sudden rapid deployment or loss of control is avoided, and the comfort and safety of the user during operation are significantly improved. The simple structure and manufacturing process of the rubber damping part make the overall design more streamlined. The rubber material itself has good durability and stability, and can maintain its friction characteristics and stable performance for a long time. This not only ensures that the damping part can still effectively control the movement of the support part 20 after long-term use, but also extends the overall service life of the protective shell and reduces the frequency of maintenance and replacement.

[0060] See also Figure 7 , Figure 8 and Fig.10 As shown, the control part 30 in the embodiment of the present application includes a limiting part 31, which is movably mounted on the housing 10. When the control part 30 is in a locked state, the limiting part 31 cooperates with the support part 20 to limit the expenditure of the support part 20; when the control part 30 is in an unlocked state, the limiting part 31 avoids the unexpended support part 20. The limiting part 31 is movably mounted on the housing 10 and cooperates with the support part 20 to limit the expansion of the support part 20 when the control part 30 is in a locked state. When the support part 20 needs to be spent, the limiting part 31 moves to avoid the support part 20, and the support part 20 is spent under the action of the thrust part.

[0061] The limiting part 31 in the embodiment of the present application is located between the housing 10 and the support part 20. The limiting part 31 includes a transmission body and a first limiting structure located on the transmission body. The first limiting structure is located on the side of the transmission body close to the support part 20. The side of the support part 20 close to the housing 10 is provided with a second limiting structure. When the control part 30 is in a locked state, the first limiting structure cooperates with the second limiting structure to limit the expenditure of the support part 20. Through the cooperation of the second limiting structure and the first limiting structure, the limiting part 31 can effectively limit the expansion of the support part 20 when the control part 30 is in a locked state. The setting of the transmission body enables the control part 30 to be controlled at a position far away from the support part 20, which provides a more convenient operation experience for the user. The user can easily control the expansion and folding of the support part 20 without being too close to the support part 20, which enhances the convenience and operational flexibility of the product. The cooperation of the second limiting structure and the first limiting structure provides a reliable operation protection function, prevents the support part 20 from being damaged due to misoperation or external interference, and also optimizes the stability and durability of the product. The first limiting structure and the second limiting structure may adopt magnetic fit, snap fit, etc.

[0062] See also Fig.10 and Fig.11As shown, the transmission body in the embodiment of the present application includes a transmission section 32, a limiting section 33 located at the first end of the transmission section 32, a first limiting structure is arranged on the limiting section 33, a guide channel 13 is arranged on the housing 10, and the transmission section 32 is movably arranged in the guide channel 13 along the extension direction of the guide channel 13. The transmission section 32 is movably arranged along the guide channel 13 on the housing 10, ensuring that the control unit 30 can still accurately control the transmission body at a remote position.
