Description

Technical Field

[0001] This invention relates to the field of electronic device accessories technology, and in particular to a protective case for electronic devices. Background Technology

[0002] Electronic devices such as tablets and mobile phones have become an indispensable part of people's daily lives. When using these devices, users often need to place them on a table or other surface to watch videos, browse the web, hold video conferences, or attend online classes. To meet these needs, various support devices that can support the tilting of electronic devices have emerged on the market.

[0003] In related technologies, support devices are mainly divided into two categories. One type is a freestanding support device, such as common phone holders and tablet holders. These holders typically consist of a base, a support backplate, and a support tray. In use, the support tray supports the electronic device from the bottom, while the support backplate provides support from the back. However, they are relatively large and need to be carried separately, making them less convenient. The other type is a support device integrated with a protective case. The protective case protects the electronic device, and the support device is located behind the case. When the electronic device is placed at an angle, the support device acts as a support between the back of the device and the table. However, this type suffers from problems such as unstable support and susceptibility to damage. Summary of the Invention

[0004] The purpose of this invention is to provide a protective case for electronic devices that is more convenient, stable, and less prone to damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electronic device protective case, comprising:

[0007] The housing has a first support area on the rear side;

[0008] A support assembly includes a first support member and a second support member; the first support member includes a first head end and a first body portion that are interconnected and rotatable relative to each other; the second support member includes a second body portion, and a second head end and a second tail end portion connected to opposite ends of the second body portion.

[0009] The support component has a first support state. When the support component is in the first support state, the first head end is adsorbed onto the first support area, the first main body is inclined relative to the shell, the second head end is connected to the shell, the second main body is inclined relative to the shell, and the second end is connected to the first main body.

[0010] When the support assembly is in the supported state, the second and first support members work together to form a triangular support effect on the housing and electronic equipment, resulting in high support stability. The second support member holds the first support member to prevent it from sliding. The first end is not fixedly connected to the housing; it can detach from the housing and its adsorption position can be adjusted, making it convenient and more flexible to use.

[0011] Optionally, a first limiting protrusion protruding relative to the housing is provided on the rear side of the housing; when the support assembly is in the first support state, the first end portion is adsorbed onto the first support area, and the first limiting protrusion restricts the first end portion from sliding downward relative to the housing. The provision of the first limiting protrusion can improve the support stability of the first support member.

[0012] Optionally, the rear side of the housing is provided with a plurality of spaced-apart first limiting protrusions; and / or, the housing and the first limiting protrusions are an integral structure. The housing and the first limiting protrusions can both be injection molded from soft or hard rubber materials such as TPU, which has good performance and helps to reduce manufacturing costs.

[0013] Optionally, the support assembly has a retracted state. When the support assembly is in the retracted state, the first support member covers the side of the second main body that is away from the housing, the first end portion is attached to the housing, and the first main body is attached to the housing. The user can retract the support assembly at any time, which is more convenient.

[0014] Optionally, the rear side of the housing also has a second support area; the support assembly has a second support state, in which the second head end is attached to the second support area, the first main body is tilted relative to the housing, the second main body is tilted relative to the housing, the second head end is connected to the housing, and the second tail end is connected to the first main body; when the support assembly is in the first support state and the second support state, the included angles between the first support member and the housing are the first included angle and the second included angle, respectively; the second included angle is smaller than the first included angle. The support assembly has multiple support states, and the electronic device tilts at different angles in different support states to meet different usage requirements.

[0015] Optionally, the second main body and the second end portion can rotate relative to each other, and the second main body and the second beginning portion can rotate relative to each other. This can meet the adjustment requirements of the support assembly in different states.

[0016] Alternatively, the second end can be fixedly connected to the housing, for example, by a glue connection, for greater reliability.

[0017] Optionally, the second end portion is fixedly connected to the first main body portion, for example, by a glue connection, which is more reliable.

[0018] Optionally, a second limiting protrusion protruding relative to the housing is provided on the front or rear side of the housing, and a second limiting groove is provided at the second end, with the second limiting protrusion engaging with the second limiting groove; when the support assembly is in the first support state, the second limiting protrusion is used to prevent the second support member from detaching from the housing. The second support member can more stably hold the first support member, and the second support member is not easily detached from the housing.

[0019] Optionally, the housing is provided with a mounting through hole, the second main body is located on the rear side of the housing, and the second head end is located on the front side of the housing. The portion connecting the second main body and the second head end passes through the mounting through hole; the second head end abuts against the front side of the housing. The second support member can more stably hold the first support member, and the second support member is not easy to fall off the housing.

[0020] Optionally, a mounting groove is provided on the front side of the housing, and the second end is embedded in the mounting groove. The second support can more stably hold the first support, and the second support is less likely to fall off the housing.

[0021] Optionally, the first main body has a slot inside, and a socket communicating with the slot is provided on the side of the first main body near the housing. The second end portion is inserted into the slot through the socket. The second support member is easy to assemble with the first support member, and the connection strength is high.

[0022] Optionally, a storage groove is provided on the rear side of the housing. When the support assembly is in the stored state, both the second main body and the first support member are housed within the storage groove. This results in an aesthetically pleasing appearance and ensures stable storage.

[0023] Optionally, the support component has a retracted state. When the support component is in the retracted state, the first head end is adsorbed onto the housing, and the first main body is adsorbed onto the housing. A clearance groove is provided on the side of the first main body near the housing. When the support component is in the retracted state, the first limiting protrusion is inserted into the clearance groove.

[0024] Optionally, the support assembly has a first supporting state, a second supporting state, and a retracted state. In the first supporting state and the second supporting state, the first end portion is magnetically attracted to the housing by magnets. In the retracted state, both the first end portion and the first main body are magnetically attracted to the housing by magnets. This solution not only meets the adjustment requirements of different states, but also has a simple housing structure and a simple first support structure, which is easy to manufacture and has high reliability.

[0025] Optionally, the first support member and the second support member include a plate and a flexible material covering the outside of the plate. The structure is simple and the adjacent parts can be adjusted to rotate relative to each other as needed.

[0026] The beneficial effects of this application are as follows: In this electronic device protective case, the case is used to protect the electronic device, and a support component is provided on the rear side of the case. In daily scenarios, users can use the support component at any time without having to carry an additional independent support device, making it more convenient to use.

[0027] Furthermore, when the user needs to place the electronic device at an angle on a table or other surface, the first support member is inclined between the housing and the table, and the second support member, located between the housing and the first support member, serves to limit the movement of the first support member. The first support member will not slip due to the weight of the electronic device or being accidentally pulled backward. A triangular support is formed between the housing, the first support member, and the second support member, making the support component of this application provide more stable support for the electronic device.

[0028] Meanwhile, when using the support component to support the electronic device, the top of the first support member is attached to the rear side of the housing by the first end. The first support member and the housing do not need to be assembled using structures such as a pivot, which avoids the problems of difficult assembly and stress concentration at the pivot position caused by setting a pivot, and is not easily damaged.

[0053] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In related technologies, support devices for electronic devices are mainly divided into two categories. One type is the independent support device, also known as a vertical bracket. This type of bracket includes a base, support plate, support back plate, etc. Although this type of bracket has high support stability, it is bulky and can only be used in fixed places such as homes, offices, and schools, which limits its use and is not convenient.

[0057] Another type is a support device integrated with a protective case, with its support structure located on the rear of the case. When the electronic device needs to be tilted, the user can easily unfold the support device to prop it between the electronic device and the table. This design greatly improves portability, allowing users to use the support function at any time. However, this type of support device still has many drawbacks: insufficient support stability, making it prone to wobbling or even collapse during use; poor durability, easily damaged under heavy pressure; and relatively heavy and expensive.

[0058] by Figure 22 Taking the protective case of some electronic devices as an example, its support device adopts a bracket 91 design. The top of the bracket 91 is rotatably connected to the housing 10 of the protective case via a pivot 92. In use, the bracket 91 is rotated open so that its bottom rests against the table. However, in actual use, due to factors such as the weight of the electronic device, insufficient damping at the position of the pivot 92, and unreasonable structural design, unstable support and easy damage are prone to occur. Figure 22 The instability of the support is clearly visible: the bottom of the stand 91 slips backward (the dotted line in the image indicates the slippage). This not only interferes with the user's viewing experience of the electronic device but may also cause the device to hit the table, resulting in damage. Regarding its susceptibility to damage... Figure 23 and Figure 24 Two common installation methods and their problems are shown respectively. Figure 23 In this design, the protective shell 10 has two spaced mounting protrusions 93 on its rear side, with the top of the bracket 91 positioned between them. Mounting holes are located on the inner sides of the mounting protrusions 93 on both sides. The rotating shafts 92 on the left and right sides of the top of the bracket 91 are inserted into these mounting holes respectively. This mounting method has two major drawbacks: First, it is difficult to install, as it is hard to accurately insert the rotating shafts 92 on both sides into the mounting holes at the same time. Second, the weight of the electronic equipment and the protective shell is transmitted to the bracket 91 through the relatively short rotating shafts 92, causing stress concentration at the location of the rotating shafts 92 (marked by the solid arrow in the figure), which makes them very easy to break, thus leading to damage to the bracket 91. Figure 24 The design involves providing two mounting protrusions 93 on the rear side of the protective shell 10 and mounting through holes 11 on the top of the bracket 91. The bracket 91 is installed by passing through these three mounting through holes 11 simultaneously with an independent rotating shaft 92. Although this method can reduce stress concentration to some extent, it requires extremely high assembly precision and has low assembly efficiency, which will inevitably increase manufacturing costs.

[0059] In addition, some related technologies use a single piece of sheet metal, roughly the same size as the electronic device, as a support for the rear of the electronic device's protective case. In use, this sheet metal can be folded into a triangular structure to support the rear of the device. This support method provides stable support for the electronic device, preventing wobbling or collapse during use and providing a good user experience. However, this support device also has significant drawbacks. Because it uses a single piece of sheet metal, the material usage is large, significantly increasing production costs and product weight. For users who prioritize portability, the heavier protective case becomes an extra burden, causing inconvenience in daily carrying and use.

[0060] Based on this, this application provides a protective case for electronic devices with a support function, providing a new support solution for electronic devices, in order to solve the problems existing in the support devices of the related technology: the independent bracket is inconvenient to carry, the back of the case can be folded to form a triangle with large weight, easy to slip and shake, and easy to be damaged.

[0061] The electronic device protective case of this application integrates the support component and the housing into one product. Compared with a single independent bracket, users carry the support component with them when carrying electronic devices, making it convenient and quick to use.

[0062] In the electronic device protective case of this application, the support component provides more stable support for the electronic device. In its supported state, the support component, through the cooperation of the first and second support members, forms a triangular support for the casing. The second support member serves to hold the first support member in place, preventing the bottom of the first support member from slipping on the table, thus providing more stable support for the electronic device. Even when the electronic device is heavy, subjected to external pressure, or the user accidentally bumps or pulls on the first support member, the support component can stably and reliably support both the casing and the electronic device.

[0063] Compared to using a single piece of sheet metal folded into a triangle for support, the electronic device support solution of this application can reduce the area occupied by the support components, save materials, reduce weight, and make it easier for users to carry.

[0064] In this application, the first support member and the housing are not directly connected by a rotating shaft, which avoids the problems of high assembly difficulty and low assembly efficiency caused by the rotating shaft connection. It is not necessary to open small mounting holes for mounting the rotating shaft in the housing and the first support member, and it is not necessary to perform a relatively precise assembly between the shaft and the hole.

[0065] In this application, the first support member is attached to the rear side of the housing via its first end cap, which has several advantages: First, the first support member and the housing do not require complex assembly; the first end cap can be directly attached to the rear side of the housing as needed, making the structure of the housing and the first support member simpler. This not only reduces manufacturing difficulty but also assembly difficulty, thus reducing costs. Second, it increases the contact area between the first support member and the housing, allowing the weight of the electronic device plus the housing to be evenly distributed to the first support member, avoiding stress concentration in local areas and reducing the risk of damage under load. Third, users can adjust the position of the first end cap and the fit of the support components as needed to meet the requirements of other usage scenarios, making it more flexible to use.

[0066] Please refer to the following. Figures 1 to 21 The present application describes a protective case for an electronic device with a support function. The protective case includes a housing 10 and a support assembly, which includes a first support member 20 and a second support member 30.

[0067] The first support member 20 includes a first head end 21 and a first body part 22. The first body part 22 and the first head end 21 are rotatably connected to each other so that the relative angle between the first body part 22 and the first head end 21 can be adjusted. Figures 1 to 3 In this configuration, the first main body portion 22 and the first end portion 21 are adjusted to different engagement angles. The second support member 30 includes a second end portion 31, a second main body portion 32, and a second end portion 33. The top of the second main body portion 32 is connected to the second end portion 31, and the bottom of the second main body portion 32 is connected to the second end portion 33. Figure 1 , Figure 2 As shown, the second support member 30 is disposed between the housing 10 and the first support member 20.

[0068] The support assembly has a first support state, in which the first support member 20 is tilted backward relative to the housing 10 to support the electronic device and the housing 10. Figure 16 This diagram illustrates the housing 10 before it is assembled with the support components, viewed from the rear. Figure 16 As shown, the rear side of the housing 10 has a first support area 101 (the straight dashed line in the figure is only for illustration purposes), and the first support area 101 is used to attract each other to the first support member 20 when the support assembly needs to be adjusted to the first support state.

[0069] Reference Figure 1 , Figure 4 , Figures 6 to 8As shown, when the support assembly is in the first support state, the first head end 21 is attached to the first support area 101 on the rear side of the housing 10. At this time, the first main body 22 is tilted away from the housing 10 relative to the first head end 21, which is equivalent to the first main body 22 also tilting backward relative to the housing 10. At the same time, the second support member 30 is located between the housing 10 and the first support member 20. The second head end 31 is connected to the housing 10, the second main body 32 is tilted relative to the housing 10, and the second end end 33 is connected to the first main body 22.

[0070] It should be noted that when describing the two components within the protective casing of this application as rotatably connected, it means that the two components are connected and their relative angle can be adjusted to at least two states. When describing the two components within the protective casing of this application as mutually adsorbed, it means that the two components are attached together by some force, but the two components can be separated from each other under the action of external force. For example, the first end 21 adsorbing onto the casing 10 means that the first end 21 and the casing 10 are mutually adsorbed by magnetic attraction or by Velcro.

[0071] Please continue to refer to Figure 8 When the support assembly is in the first support state, the electronic device and the housing 10 can be placed tilted on the table. The first main body 22 is tilted between the housing 10 and the table, and the second support member 30 located between the first main body 22 and the housing 10 acts to hold the first support member 20. At this time, even if the electronic device is heavy, or the electronic device is subjected to backward or downward pressure, or the first support member 20 is accidentally pulled backward, the first support member 20 can be maintained at its current tilt angle because the second support member 30 can hold it, thereby stably supporting the housing 10 and the electronic device.

[0072] For example, the first end portion 21 and the housing 10 are attracted to each other based on magnetic attraction.

[0073] When designing the protective case for the electronic device, the inventors initially only considered including the first support member 20 as described in this application. However, the inventors discovered that this could lead to two situations: firstly, the first end portion 21 might slide downwards relative to the housing 10; secondly, the bottom end of the first main body portion 22 might slide backwards on the table, increasing the angle between the first main body portion 22 and the housing 10 and increasing the risk of the electronic device falling over. The inventors considered improving the downward sliding problem of the first end portion 21 relative to the housing 10 by increasing the magnetic attraction between the first end portion 21 and the housing 10. However, increasing the magnetic attraction requires increasing the thickness or area of ​​the magnet, which would bring new problems, such as increased cost and weight. Furthermore, this method could not overcome the problem of the bottom end of the first main body portion 22 sliding backwards.

[0074] The configuration of the protective casing for the electronic device in this application can improve both the problem of the first end portion 21 sliding downward relative to the casing 10 and the problem of the bottom of the first main body portion 22 sliding backward. For example... Figure 8 As shown, when the electronic device is placed at an angle, the weight of the electronic device itself, the weight of the housing 10, and the downward and backward pressure exerted on the electronic device by the user when touching it all act directly on the first support member 20. At this time, even if the first end portion 21 tends to slide downward and the bottom of the first main body portion 22 tends to slide backward due to the large force of these forces, the second support member 30 can exert a pulling force F12 on the first main body portion 22. At this time, when this pulling force F12 acts on the first body portion, it will manifest as a pulling force F12a that overcomes the backward sliding of the bottom of the first body portion, and when the pulling force F12 acts on the first end portion 21, it will manifest as keeping it in contact with the housing 10, thus making it less likely to slide downward.

[0075] Thus, the support components of this application can also provide stable support for electronic devices in the following scenarios: when the electronic device is a tablet computer with a large self-weight; when the user needs to perform touch, writing, drawing and other operations on the screen of the electronic device and applies a large amount of pressure to the screen of the electronic device; when the user accidentally pulls on the first main body 22.

[0076] Please refer to Figure 4 , Figure 8 , Figure 10 In one embodiment, to improve the support stability of the support component when it is in a supported state, a first limiting protrusion 41 protruding relative to the housing 10 is also provided on the rear side of the housing 10. The first end portion 21 is adsorbed onto the first support region 101. The first limiting protrusion 41 is located on the bottom side of the first end portion 21. The first limiting protrusion 41 is used to restrict the first end portion 21 from sliding relative to the housing 10 towards the lower side of the housing 10 (i.e., the side of the housing 10 that contacts the table). (Refer to...) Figure 8 In the enlarged view of section C, in the first supported state, the first limiting protrusion 41 abuts against the bottom of the first head end 21, and the first limiting protrusion 41 supports the first head end 21 from bottom to top, as shown... Figure 8 The first limiting protrusion 41 provides a supporting force F11, which makes it difficult for the first end portion 21, which is attached to the housing 10 by magnetic force or Velcro, to slide downward. This keeps the first end portion 21 stably in its current position, thereby keeping the first main body 22 at its current tilt angle, and thus keeping the electronic device at its current tilt angle, achieving stable and reliable support for the electronic device.

[0077] In this embodiment, not only is the first main body 22 held in place by the second support member 30, but the first end portion 21 is also supported by the first limiting protrusion 41. In the first supported state, based on the second support member 30 and the first limiting protrusion 41, the first support member 20 is subjected to forces F12 and F11, which can improve the stability of the support assembly in supporting the tilted electronic device and improve the safety of the electronic device. It can be understood that compared with increasing the volume of the magnet, or compared with connecting the first end portion 21 to the housing 10 through a rotating shaft, this embodiment, by setting the first limiting protrusion 41 to support the first end portion 21, can prevent the first end portion 21 from sliding down with a simpler structure.

[0078] Optionally, the rear side of the housing 10 is provided with multiple first limiting protrusions 41, which are spaced apart in the left-right direction. The left-right direction refers to the direction of the user's left and right hands when the electronic device is placed on a table and the screen of the electronic device is facing the user. The multiple first limiting protrusions abut against the first end portion 21 to support the first end portion 21 from multiple positions, so that the support force is applied more evenly and the support effect is better, avoiding situations such as "the left side of the first end portion 21 sliding down while the right side is supported and held in place". Compared with a limiting protrusion with a long strip, the multiple first limiting protrusions 41 arranged at intervals occupy less space and do not affect the subsequent storage of the first support member 20 and the second support member 30.

[0079] Optionally, the back of the housing 10 is provided with two spaced first limiting protrusions 41.

[0080] In other embodiments, the first limiting protrusion 41 on the back of the housing 10 may also be an elongated protrusion extending in the left-right direction.

[0081] Optionally, to simplify the protective shell structure and facilitate manufacturing, the shell 10 and the first limiting protrusion 41 are integrated into a single structure; that is, the shell 10 and the first limiting protrusion 41 are integrally connected through a molding process. During production, there is no need to assemble the shell 10 and the first limiting protrusion 41 separately; they are combined into one component, making manufacturing more convenient and efficient, and reducing the risk of damage to the first limiting protrusion 41. For example, the shell 10 and the first limiting protrusion 41 are connected through a single injection molding or a two-stage injection molding process.

[0082] In other embodiments, the first limiting protrusion 41 can also be connected to the housing 10 by means of snap-fitting, snap-fitting, or adhesive fixing.

[0083] Optionally, the housing 10 and the first limiting protrusion 41 are injection-molded soft rubber parts. For example, both the housing 10 and the first limiting protrusion 41 are made of TPU (Thermoplastic Polyurethanes), an innovative material between rubber and plastic. TPU has high tensile strength and exhibits good wear resistance and anti-aging properties, with outstanding wear resistance. The soft rubber housing 10 will not scratch the surface of the electronic device. Furthermore, the surface of the soft rubber first limiting protrusion 41 has a certain friction, resulting in better limiting effect on the first end portion 21 when the first limiting protrusion 41 contacts it.

[0084] In other embodiments, the housing 10 and the first limiting protrusion 41 may also be made of hard plastic or the like.

[0085] In one embodiment, please refer to Figure 3 , Figures 13 to 15 To facilitate carrying electronic devices, the support assembly has a retracted state. When the support assembly is in the retracted state, the first support member 20 covers the side of the second main body 32 facing away from the housing 10, the first end portion 21 is adsorbed onto the housing 10, and the first main body 22 is adsorbed onto the housing 10. For example, the first end portion 21 and the first main body 22 are held adsorbed onto the housing 10 by the magnetic attraction of a magnet or by Velcro.

[0086] Continue to refer to Figure 14 , Figure 15 When the support components are not needed, the first support member 20 and the second support member 30 need to be stored for easy handling and carrying in a bag. In this embodiment, the storage method involves detaching the first end portion 21 from the first support area 101 or the second support area 102, for example, separating the first end portion 21 from the housing 10. At this time, the first support member 20 can be adjusted to be approximately parallel to the housing 10. During this process, the second support member 30 rotates to be approximately parallel to the housing 10. Then, the first support member 20 is brought against the housing 10, allowing the first end portion 21 and the first main body 22 to be magnetically attracted to the housing 10. Thus, the first support member 20 and the second support member 30 can be simultaneously stored flat on the rear side of the housing 10. Furthermore, the second support member 30 does not need to be magnetically attached to the housing 10; instead, it is covered by the first support member 20. The storage method in this embodiment is simple, quick, easy to operate, and has low operational difficulty. Users can complete the storage by operating the first support member 20 with only one hand.

[0087] (The fourth supplementary option has limited inventiveness and has not yet been included in the claims.)

[0088] Optionally, the rear side of the housing 10 has a third region 103 and a fourth region 104, with a first support region 101 located between the third region 103 and the fourth region 104. When the support assembly is in a retracted state, the first end portion 21 is adsorbed onto the third region 103, and the first main body portion 22 is adsorbed onto the fourth region 104. Exemplarily, the opposite sides of the housing 10 have an upper frame portion and a lower frame portion. When the electronic device is tilted, the lower frame portion rests on a table. Along the direction from the upper frame portion to the lower frame portion, the third region 103, the first support region 101, and the fourth region 104 are sequentially distributed.

[0089] Optionally, the rear side of the housing 10 is provided with two first limiting protrusions 41. In the storage state, the two first limiting protrusions 41 are located on the left and right sides of the second support member 30. The first support member 20 completely covers the second support member 30, and the first support member 20 also covers the two first limiting protrusions 41, which takes into account both the aesthetics when stored and the stability in the supported state.

[0090] In one embodiment, to meet the user's needs in different scenarios, the support component is configured to support the electronic device at at least two tilt angles. The support component is configured to have at least a first support state and a second support state, wherein the included angle between the first support member 20 and the housing 10 is different in different support states. (Refer to...) Figure 16 The rear side of the housing 10 also has a second support region 102. (Refer to...) Figure 2 , Figure 5 , Figure 11 , Figure 12 The support component has a second support state. When the support component is in the second support state, the second head end 31 is attached to the second support area 102, the first main body 22 is tilted relative to the housing 10, the second main body 32 is tilted relative to the housing 10, the second head end 31 is connected to the housing 10, and the second tail end 33 is connected to the first main body 22. It can be understood that by adjusting the position of the first head end 21 attached to the housing 10, the included angle α between the first main body 22 and the housing 10 can be adjusted, thereby adjusting to different support states so that the tilt angle of the electronic device screen relative to the desktop is different, meeting different usage needs.

[0091] For example, the second support region 102 is located above the first support region 101, referring to... Figure 4 , Figure 7 When the support assembly is in the first support state, the included angle between the first support member 20 and the housing 10 is the first included angle α1; refer to Figure 5 , Figure 12 When the support assembly is in the second support state, the included angle between the first support member 20 and the housing 10 is the second included angle α2; the second included angle α2 is smaller than the first included angle α1. (Refer to...) Figure 4 , Figure 5 When it is necessary to tilt the screen of the electronic device more, the first end 21 is attached to the first support area 101 which is lower in the housing 10, so that the angle between the back of the electronic device and the table is smaller.

[0092] It should be noted that only one set of first limiting protrusions 41 can be provided to limit the first support member 20 at the most commonly used angle. For example, in the first support state, the first supporting member 20 is supported by the first limiting protrusions 41 to prevent the first end portion 21 from sliding down. In other embodiments, multiple sets of first limiting protrusions 41 can also be provided so that the first end portion 21 can be supported by different sets of limiting protrusions in different support states.

[0093] In one embodiment, to simplify the structure and facilitate assembly, the second support member 30 is configured such that the second main body portion 32 and the second end portion 33 can rotate relative to each other, and the second main body portion 32 and the second head end portion 31 can rotate relative to each other.

[0094] Taking a support assembly having a first support state, a second support state, and a stowed state as an example, in this embodiment, the second main body 32 is rotatable relative to the second head end 31 and the second tail end 33, and the first main body 22 is rotatable relative to the first head end 21. Thus, when the second support member 30 remains connected to both the housing 10 and the first support member 20, the angle α of the first main body 22 relative to the housing 10 and the angle β of the second main body 32 relative to the housing 10 can both be adjusted. Therefore, to adjust the support angle of the electronic device or to stow the support assembly, it is not necessary to separate the second support member 30 from the housing 10 or from the first support member 20. The user only needs to adjust the position of the first head end 21, attaching it to the first support area 101, the second support area 102, or the third area 103 on the top side, to adjust the support assembly to the first support state, the second support state, or the stowed state. In this way, even if the user operates with one hand, it is easy to adjust the position of the first end 21, thereby adjusting the support angle of the support component or storing the support component. The adjustment of the support component can be achieved with one hand, which is convenient and quick, and the operation requires low precision and is easy to operate.

[0095] like Figure 7 , Figure 12 As illustrated, when the support component is adjusted from the first support state to the second support state, angle α decreases, and angle β decreases. When the support component is in the retracted state, angles α and β are between 0 degrees and 5 degrees.

[0096] Optionally, the second end portion 31 is fixedly connected to the housing 10.

[0097] Optionally, the second end portion 33 is fixedly connected to the first main body portion 22.

[0098] The second head end 31 can be connected to the housing 10, and the second tail end 33 can be connected to the first body part 22 by means of adhesive, welding, screws, or other methods. For example, the second head end 31 is connected to the housing 10 by hot melt adhesive, and the second tail end 33 is connected to the first body part 22 by hot melt adhesive.

[0099] Compared to schemes where the second end portion 31 is connected to the housing 10 and the second end portion 33 is connected to the first main body portion 22 via magnetic attraction or other means, both ends of the second support member 30 are fixedly connected to the housing 10 and the first support member 20, such as... Figure 8 This means that, in the supported state, slippage at both ends of the second support member 30 can be avoided, thereby allowing the second support member 30 to maintain its current angle and provide a stable pulling force to the first main body 22, effectively preventing slippage at both ends of the first support member 20.

[0100] Understandably, when the second end portion 31 is relatively fixedly connected to the housing 10, and the second end portion 33 is relatively fixedly connected to the first main body portion 22, the housing 10, the second support member 30, and the first support member 20 form an integral component, preventing any support member from being lost and ensuring that the support function can be used normally. The first end portion 21 can be attached to different areas of the housing 10 as needed, and in conjunction with the second main body portion 32, it can rotate relative to the first main body portion 22 and the housing 10. This allows the housing 10 and the two support members to form an integral component while also facilitating the adjustment of the angles of the first main body portion 22 and the second main body portion 32, adjusting the support assembly to the target state.

[0101] In designing the protective shell, the inventor considered the following configuration to accommodate the angle adjustment of the first support member 20: a groove is provided on the rear side of the shell 10, and mounting grooves extending from top to bottom are provided on the left and right sides of the groove; first shafts are provided on the left and right sides of the top of the first support member 20, and the two first shafts are slidably mounted in the mounting grooves; the first main body 22 and the second support member 30 are rotatably connected via the second shaft, and the second support member 30 and the shell 10 are rotatably connected via the third shaft. Although this method can also achieve the adjustment of the support angle of the first support member 20 and can also accommodate the two support members, this structure still has the aforementioned problems of difficult assembly between the groove and the shaft, and easy stress concentration; secondly, during use, impurities can easily enter the mounting grooves on the left and right sides of the shell 10 and block the sliding channel of the first shaft, which will prevent the angle of the first support member 20 from being adjusted smoothly; furthermore, if the user applies improper force when adjusting the angle of the first support member 20, it can easily cause the first shaft to break.

[0102] In addition, to allow the first support member to be angle-adjustable, the inventors also considered configuring the protective shell in the following ways: such as Figure 25 The configuration of the first support member 20 is the same as in this application. The second support member 30 is rotatably connected to the housing 10, but not connected to the first support member 20. Multiple locking protrusions 94 are provided on the second support member 30. When supporting the electronic device, the second support member 30 is laid flat, and then the end of the first support member 20 is locked inside the appropriate locking protrusions 94 to stabilize the angle of the first support member 20. However, this structure makes the first support member 20 an independent component, with no physical connection to the second support member 30 or the housing 10. This makes it easy for the first support member 20 to be lost during use, rendering the protective housing support function unusable.

[0103] In one embodiment, to strengthen the connection between the second support member 30 and the housing 10, and to keep the first support member 20 stable when the support assembly is in a supported state, thereby improving the support stability of the electronic device, a limiting fit is provided between the housing 10 and the second head end 31. The assembly between the second head end 31 and the housing 10 can be achieved through at least one or more of the following methods:

[0104] One of the assembly methods between the second end portion 31 and the housing 10: Please refer to Figure 9 , Figure 17 , Figure 19 , Figure 8 A second limiting protrusion 42 protruding relative to the housing 10 is provided on the front or rear side of the housing 10, and a second limiting groove is provided on the second end portion 31. The second limiting protrusion 42 is engaged with the second limiting groove. When the support assembly is in the first support state, the second limiting protrusion 42 is used to prevent the second support member 30 from detaching from the housing 10.

[0105] like Figure 8 , Figure 19 To illustrate, taking the second end portion 31 fixed to the front side of the housing 10 with hot melt adhesive as an example, when the support assembly is in a supported state at any angle, the first main body 22 tends to move backward under the weight of the electronic device or external force. At this time, the second main body 32 is subjected to a roughly backward pulling force. If the pulling force acting on the second main body 32 is too large, it will cause the second end portion 31 to tend to slide parallel to the housing 10. This may cause the adhesive layer in the middle to be excessively stretched, and long-term use may cause the second end portion 31 to fall off the housing 10. In this assembly method, the second limiting protrusion 42 is inserted into the second limiting groove, and the second limiting protrusion 42 restricts the second end portion 31 from sliding along a path parallel to the surface of the housing 10. Figure 8The enlarged view of part D shows that under the action of the second limiting protrusion 42, a force F21 is applied to the second head end 31. F21 enables the second head end 31 to resist the tensile force and remain in its original position, preventing connection failure between the second head end 31 and the housing 10 during long-term use. Therefore, the setting of the second limiting protrusion 42 can ensure the connection strength between the second head end 31 and the housing 10, improving durability. In addition, the setting of the second limiting protrusion 42 also serves to position the second head end 31 during installation, improving assembly efficiency and reducing assembly difficulty.

[0106] Optionally, the second limiting protrusion 42 is an integral structure with the housing 10.

[0107] Optionally, a first limiting protrusion 41 is provided on the rear side of the housing 10, and a second limiting protrusion 42 is provided on the front side. The first limiting protrusion 41 and the second limiting protrusion 42 are formed on the housing 10 by injection molding to form a single component with the housing 10. This reduces the types of materials used, simplifies the structure, and increases structural strength and manufacturing efficiency. It is understandable that when the housing 10 used to protect electronic devices is made of soft rubber, it is convenient to directly form both limiting protrusions while molding the housing 10 through mold design.

[0108] The second assembly method between the second end 31 and the housing 10: Please refer to... Figure 8 , Figure 16 , Figure 17 , Figure 19 The housing 10 is provided with a mounting through hole 11. The second main body 32 is located on the rear side of the housing 10, and the second head end 31 is located on the front side of the housing 10. The portion where the second main body 32 and the second head end 31 connect is inserted into the mounting through hole 11; the second head end 31 abuts against the front side of the housing 10. (Continue referring to...) Figure 8 When the support assembly is in the supported state, the second main body 32 is subjected to a roughly rearward pulling force. At this time, the second main body 32 is subjected to an upward and oblique supporting force F22 from the front side of the housing 10. F22 enables the second head end 31 to resist the pulling force of the second main body 32 and remain in the original position, thereby improving the connection strength between the second head end 31 and the housing 10.

[0109] The third assembly method between the second end 31 and the housing 10: Please refer to... Figure 17 When the second end portion 31 is located on the front side of the housing 10, a mounting groove 12 is provided on the front side of the housing 10; or, when the second end portion 31 is located on the rear side of the housing 10, a mounting groove 12 is provided on the housing 10 (not shown in the figure). Figure 19As shown, the second end portion 31 is embedded in the mounting groove 12. The mounting groove 12 facilitates the filling of hot melt adhesive into the groove, allowing the second end portion 31 to be inserted into it, thus connecting the second end portion 31 to the housing 10. Furthermore, the surface of the second end portion 31 is flush with the surface of the housing 10 after installation, resulting in a more aesthetically pleasing appearance. Additionally, the mounting groove 12 provides a limiting effect on the second end portion 31, which helps improve installation strength.

[0110] It is understandable that by configuring a protective shell through one or more of the aforementioned assembly methods one, two, and three between the second end 31 and the housing 10, the tensile strength of the connection between the second support member 30 and the housing 10 can be strengthened. Strengthening the tensile strength of key parts ensures stable support for electronic devices in the supported state, preventing wobbling and slippage, while also taking into account the convenience of manufacturing the housing 10, manufacturing the second support member 30, and assembling the housing 10 and the second support member 30.

[0111] In other embodiments, the second end portion 31 is disposed on the rear side of the housing 10, and / or the housing 10 is not provided with the mounting groove 12.

[0112] In one embodiment, please refer to Figure 20 , Figure 21 The first main body 22 has a slot 222 inside, and a socket 2221 communicating with the slot 222 is provided on the side of the first main body 22 near the housing 10. The second end part 33 is inserted into the slot 222 through the socket 2221, and the second end part 33 is connected to the housing 10 by adhesive material such as hot melt adhesive. The slot 222 not only strengthens the limiting fit between the second end part 33 and the first main body 22, thus strengthening the connection between them, but also increases the area that can be bonded between the second end part 33 and the first main body 22 by adhesive material during assembly, further strengthening the connection between them.

[0113] Compared to the method of directly attaching the shell 10 to the surface of the first main body 22, the design of the slot 222 in this embodiment can improve the connection strength between the second end portion 33 and the first main body 22. The second end portion 33 is inserted into the slot 222 of the first main body 22. While ensuring connection strength and limiting effect, it eliminates the need for additional limiting protrusions on the surface of the second support member 30 or the first support member 20. Therefore, the first support member 20 and the second support member 30 do not need to be made of injection-molded soft rubber; the two support members can be structures such as fiberglass boards wrapped in leather.

[0114] It is understandable that, since the two ends of the second main body 32 are approximately hinged to the housing 10 and the first main body 22, when the support assembly switches between the first support state, the second support state, and the storage state, the second main body 32 can rotate relative to the housing 10 and relative to the first main body 22 to adapt to the corresponding adjustments and meet the adjustment of multiple states.

[0115] Optionally, the thickness direction of the slot 222 is consistent with the thickness direction of the first main body portion 22, that is, the slot 222 is parallel to the first main body portion 22. (Refer to...) Figure 21 The slot 222 has a first groove wall and a second groove wall. The side of the second end portion 33 near the housing 10 abuts against the first groove wall, and the side of the second end portion 33 away from the housing 10 abuts against the second groove wall. The insertion port 2221 is located at the first groove wall. By extending the slot 222 approximately parallel to the first main body portion 22, the thickness of the first main body portion 22 can be effectively utilized, and the slot 222 can be guaranteed to have a certain area, ensuring a reliable connection strength between the second support member 30 and the first support member 20 after the second end portion 33 is inserted into the slot 222.

[0116] In one embodiment, in order to balance storage effectiveness and aesthetic appeal in the folded state, reference is made to... Figure 2 , Figure 16 , Figure 18 A storage groove 13 is provided on the rear side of the housing 10. When the support assembly is in the stored state, both the second main body 32 and the first support member 20 are located within the storage groove 13. On the one hand, this makes the rear side of the protective housing appear roughly flat when stored, resulting in a more aesthetically pleasing appearance. On the other hand, when stored, the edges of the second support member 30 and the first support member 20 are largely covered by the groove wall of the storage groove 13, reducing the likelihood of fingers, pens, cards, or other objects accidentally touching the edge of the first support member 20 and causing it to detach from the housing 10. This allows the first support member 20 to be more stably attached and held on the rear side of the housing 10, resulting in high storage stability.

[0117] Optionally, refer to Figure 15 In the folded state, the bottom of the first support member 20 extends outward relative to the housing 10, so that the user can use their fingers to hold the extended part at the bottom to lift the first support member 20 and make it convenient to use the support assembly.

[0118] Optionally, refer to Figure 16 , Figure 18The storage recess 13 actually includes a first storage groove and a second storage groove disposed at the bottom of the first storage groove. The area of ​​the second storage groove is smaller than that of the first storage groove. In the stored state, the second main body 32 is embedded in the second storage groove, and the first support member 20 is entirely embedded in the first storage groove. This stepped storage groove design, in the stored state, can not only accommodate two support members simultaneously, but also the groove wall of the second storage groove has a limiting effect on the second support member 30 in the interlayer, resulting in better storage stability.

[0119] Optionally, refer to Figure 20 , Figure 10 A first limiting protrusion 41 is provided on the rear side of the housing 10. To balance the aesthetics and stability of the support component in its retracted state, the first support member 20 is configured such that a clearance groove 221 is provided on the side of the first support member 20 closest to the housing 10, corresponding to the position of the first limiting protrusion 41. When the support component is in its retracted state, the first limiting protrusion 41 is inserted into the clearance groove 221, and the first support member 20 covers the first limiting protrusion 41. Thus, in the retracted state, not only is the first limiting protrusion 41 not visible from the outside, improving aesthetics, but the inner side of the first support member 20 can also abut well against the rear surface of the housing 10, allowing the first support member 20 to be more reliably attached to the housing 10, resulting in good storage stability.

[0120] In one embodiment, the support assembly has the aforementioned first support state, second support state, and storage state. In different states, the first support member 20 is located at different positions on the housing 10 by magnetic attraction. Compared to the method of attaching the first support member 20 to the housing 10 using nylon adhesive, using magnetic force to attach the first support member 20 to the housing 10 allows the magnet to be built into the housing 10 and the first support member 20, resulting in a more aesthetically pleasing appearance. Furthermore, the magnetic attraction method helps to improve the service life of the support assembly.

[0121] Optionally, the rear side of the housing 10 has a first support region 101, a second support region 102, a third region 103, and a fourth region 104, arranged sequentially from the upper frame to the lower frame of the housing 10. The electronic device includes a first magnet 51, a second magnet 52, a third magnet 53, a fourth magnet 54, a fifth magnet 55, and a sixth magnet 56. The first magnet 51 is disposed at the first end portion 21, and the second magnet 52 is disposed at the second main body portion 32. The third magnet 53 is disposed on the housing 10 and located in the first support region 101, the fourth magnet 54 is disposed on the housing 10 and located in the third region 103, the fifth magnet 55 is disposed on the housing 10 and located in the fourth region 104, and the sixth magnet 56 is disposed on the housing 10 and located in the second support region 102.

[0122] When the support assembly is in the first support state, the first magnet 51 and the third magnet 53 attract each other so that the first end 21 is magnetically attracted to the first support area 101, and the second magnet 52 is idle.

[0123] When the support assembly is in the second support state, the first magnet 51 and the sixth magnet 56 attract each other so that the second head end 31 is magnetically attracted to the second support area 102, and the second magnet 52 is idle.

[0124] When the support assembly is in the retracted state, the first magnet 51 and the fourth magnet 54 attract each other, and the second magnet 52 and the fifth magnet 55 attract each other, so that the first head end 21 is magnetically attracted to the third region 103 and the first body part 22 is attracted to the fourth region 104.

[0125] The first magnet 51 provided at the first end 21 is used to attract magnets at different positions in the first support state, the second support state, and the storage state. The structure is reasonably designed and helps to simplify the structure.

[0126] In one embodiment, to achieve a simpler manufacturing process, a simpler assembly scheme, a more aesthetically pleasing appearance, and to ensure the performance of the two support members, the first support member 20 is configured as follows: the first support member 20 includes a first plate portion, a second plate portion, and a first flexible material; the first plate portion and the second plate portion are spaced apart. The first head portion 21 includes the first plate portion and the first flexible material covering its exterior, and the first body portion 22 includes the second plate portion and the first flexible material covering its exterior. The first head portion 21 and the first body portion 22 are connected by the first flexible material.

[0127] Correspondingly, the second support member 30 is provided in the following manner. The second support member 30 includes a third plate portion, a fourth plate portion, a fifth plate portion, and a second flexible material; the third plate portion and the fourth plate portion are spaced apart, and the fourth plate portion and the fifth plate portion are spaced apart. The second beginning end portion 31 includes the third plate portion and the second flexible material covering its exterior, the second main body portion 32 includes the fourth plate portion and the second flexible material covering its exterior, and the second end portion 33 includes the fifth plate portion and the second flexible material covering its exterior. The second beginning end portion 31 and the second main body portion 32, and the second main body portion 32 and the second end portion 33 are connected by the second flexible material.

[0128] Each plate provides structural support, while the flexible material covering the plate protects it and enhances its aesthetic appeal. Furthermore, the flexible material connecting adjacent plates allows for simple manufacturing processes, enabling relative rotation between the first end portion 21 and the first main body portion 22, between the second end portion 31 and the second main body portion 32, and between the second main body portion 32 and the second end portion 33. This eliminates the need for a pivot, resulting in a simple structure, high processing efficiency, and high reliability.

[0129] Optionally, the first, second, third, fourth, and fifth panels are all made of fiberglass board. The first and second flexible materials are both leather-like materials. Fiberglass board, as the panel material, possesses high strength and rigidity, and is easily processed and shaped using conventional cutting and stamping processes. The outer leather-like material has good flexibility, toughness, and aesthetics, and serves as a buffer and shock absorber, further enhancing the durability of the support component.
