Description

Technical Field

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

[0002] Protective cases, as a common accessory for electronic devices, provide good protection against drops and impacts. With the continuous development of internet technology and the rise of short videos, social sharing platforms, and live streaming, users have more diverse scenarios for using electronic devices. This has led to significant growth in the protective case industry, with cases integrating various functions such as stands and wrist straps, expanding their application scenarios.

[0003] A stand mounted on a protective case typically opens relative to the case for support. The angle at which the stand opens allows for different tilt angles of the electronic device relative to the desktop. Users can adjust the stand's rotation angle to their preference for optimal tilt. However, since the stand can only open in one direction, users can usually only adjust the tilt angle when using the device in landscape or portrait mode. This is insufficient for users who frequently use the device in both landscape and portrait modes, as existing stands cannot meet their specific needs. Utility Model Content

[0004] This application discloses a protective shell, including a shell, a support member, a hinge structure, and a rotating base.

[0005] The support member is rotatably connected to the rotating seat via the hinge structure, and the rotating seat is connected to the housing and can rotate relative to the housing;

[0006] The rotating base includes a first rotating component, a second rotating component, and a third rotating component stacked and fixedly connected. The housing has a receiving cavity and a mounting hole. The rotating base is disposed in the mounting hole. A mounting portion protrudes from the side wall of the mounting hole. The rotating base has a mounting groove. The mounting portion is disposed in the mounting groove. The first rotating component is disposed on the side of the mounting portion away from the receiving cavity. The third rotating component is disposed on the side of the mounting portion facing the receiving cavity. The mounting portion surrounds the outer periphery of the second rotating component and is sandwiched between the first rotating component and the third rotating component.

[0007] The hinge structure includes a first hinge and a pivot. The first hinge is fixedly connected to the second rotating member, and the support member is rotatably connected to the first hinge through the pivot.

[0008] Compared with the prior art, this application has at least the following beneficial effects:

[0009] The protective case provided by this utility model features a rotating base that allows the support to rotate relative to the case. When using the electronic device, the user can change the opening direction of the support relative to the device by rotating the base, depending on the scenario (e.g., landscape or portrait use). Simultaneously, the rotatable connection between the support member and the rotating base allows the support member to rotate relative to the protective case in different opening directions, thereby adjusting the tilt angle of the electronic device. In other words, regardless of whether the user is using the electronic device in landscape or portrait mode, the tilt angle can be adjusted by rotating the support member to achieve the optimal tilt angle and improve the user experience.

[0010] Furthermore, by configuring the rotating base as a stacked and fixedly connected first rotating component, second rotating component, and third rotating component, the first rotating component, second rotating component, and third rotating component can be made of different materials according to the force, structural performance, etc., which not only ensures the strength of the rotating base itself, but also effectively reduces the weight of the rotating base itself.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In this application, the terms "upper," "inner," "outer," "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0030] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] Furthermore, the terms "provided with" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0033] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0034] See Figures 1-5The protective case provided in this application includes a housing 1, a support member 2, a hinge structure 3, and a rotating base 4. The support member 2 is connected to the rotating base 4 via the hinge structure 3, and the rotating base 4 is connected to the housing 1 and can rotate relative to the housing 1. Since the support member 2 is connected to the rotating base 4, when the rotating base 4 rotates relative to the housing 1, it can drive the support member 2 to move together. Taking a mobile phone protective case as an example, when using a mobile phone, users usually have a portrait mode, such as watching short videos or browsing information in portrait mode; at the same time, when watching long videos or needing to watch videos on a large screen, users will turn the phone horizontally to use it in landscape mode. The setting of the rotating base 4 allows the support member 2 to rotate relative to the housing 1 with the rotating base 4. When the user uses the phone in portrait mode, the rotating base 4 drives the support member 2 to rotate so that the axis of the support member 2 is in the width direction of the phone. At this time, the support member 2 can open relative to the rotating base 4 to provide support, and the tilt angle of the phone can be adjusted by adjusting the opening angle. When a user switches to landscape mode for their phone, rotating the rotating base 4 causes the support member 2 to rotate as well, with its axis aligned with the length of the phone. At this point, the support member 2 can also open relative to the rotating base 4 to provide support. Furthermore, the tilt angle of the phone can be adjusted by changing the opening angle. Therefore, regardless of whether the user is using the electronic device in landscape or portrait mode, the tilt angle can be adjusted by rotating the support member to achieve the optimal tilt angle and enhance the user experience.

[0035] Furthermore, the rotating base 4 includes a first rotating component 41, a second rotating component 42, and a third rotating component 43 stacked and fixedly connected. In this embodiment, the first rotating component 41, the second rotating component 42, and the third rotating component 43 are stacked together sequentially. In other embodiments, the three components may not be stacked sequentially, that is, other components may be provided between them. The housing 1 is provided with a receiving cavity and a mounting hole 11. Taking a mobile phone case as an example, the mobile phone is inserted into the receiving cavity so that the mobile phone case is fitted onto the mobile phone. The rotating base 4 is provided in the mounting hole 11, and the side wall of the mounting hole 11 is provided with a mounting part 11a. The rotating base 4 is provided with a mounting groove 44, and the mounting part 11a is provided in the mounting groove 44 to realize the connection between the rotating base 4 and the housing 1. The first rotating member 41 is located on the side of the mounting portion 11a away from the receiving cavity, and the third rotating member 43 is located on the side of the mounting portion 11a facing the receiving cavity. The mounting portion 11a surrounds the outer periphery of the second rotating member 42 and is sandwiched between the first rotating member 41 and the third rotating member 43. The hinge structure 3 includes a first hinge 31 and a pivot 32. The first hinge 31 is fixedly connected to the second rotating member 42, and the support member 2 is rotatably connected to the first hinge 31 via the pivot 32. That is, the first hinge 31 is fixed on the second rotating member 42, and the support member 2 can rotate relative to the first hinge 31 via the pivot 32, thereby rotating relative to the base 4, to open for support or to be stored on the housing 1.

[0036] In some embodiments, see Figure 7 and Figure 8 The first rotating member 41 has an upper surface 41a and a lower surface 41b. At least one protruding post 411 is provided on the lower surface 41b. The protruding post 411 passes sequentially through the second rotating member 42 and the third rotating member 43, and is fixedly connected to the third rotating member 43. In the embodiment shown in the figure, there are multiple protruding posts 411 (at least two). The second rotating member 42 has multiple second through holes 424, and the third rotating member 43 has multiple third through holes 431. The number of protruding posts 411, second through holes 424, and third through holes 431 are equal. The protruding post 411 passes sequentially through the second through holes 424 and the third through holes 431, and is riveted to the third rotating member 43 to ensure that the first rotating member 41, the second rotating member 42, and the third rotating member 43 do not separate from each other when the rotating seat 4 rotates relative to the housing 1.

[0037] In some embodiments, continue reading Figure 8 To facilitate the rotation of the first rotating component 41, the first rotating component 41 is designed with a semi-circular structure. The first rotating component 41 also includes an arc-shaped side 41d and a straight side 41c located between the upper surface 41a and the lower surface 41b. The straight side 41c is recessed towards the arc-shaped side 41d to form a storage space 412, and the rotating shaft 32 is disposed within the storage space 412. By providing the storage space 412 to accommodate the rotating shaft 32, the overall structure of the rotating base 4 is made more compact, which is more conducive to the thinning of the protective shell.

[0038] In some embodiments, see Figure 9 The second rotating member 42 includes a clearance portion 423, a first connecting portion 421, and a second connecting portion 422. The first connecting portion 421 is fixedly connected to a portion of the first hinge 31, and another portion of the first hinge 31 extends into the clearance portion 423. The protrusion 411 passes through the second connecting portion 422 and is fixedly connected to the third rotating member 43. By providing the clearance portion 423, on the one hand, the arrangement and movement of the first hinge 31 are not affected; on the other hand, the arrangement of the first hinge 31 and the rotating base 4 is more compact in the thickness direction of the rotating base 4.

[0039] Furthermore, the clearance portion 423 may be a first through hole extending through the second rotating member 42 along its thickness direction, wherein the first through hole is jointly formed by the first connecting portion 421 and the second connecting portion 422. In other embodiments, the clearance portion 423 may also be a groove structure that does not extend through the second rotating member 42.

[0040] In some embodiments, see Figure 10The first hinge includes a third connecting part 311, a first buffer part 312, and a fourth connecting part 313. The third connecting part 311 is fixedly connected to the first connecting part 421. The fixing method can be riveting, welding, etc. In this embodiment, welding is used because welding is a simple process and the connection is firm. The fourth connecting part 313 is connected to the rotating shaft 32. The first buffer part 312 and the fourth connecting part 313 extend into the clearance part 423. Specifically, the fourth connecting part 313 has two protruding lugs, each of which has a shaft hole. The two ends of the rotating shaft 32 are respectively inserted into the two shaft holes to realize the connection between the fourth connecting part 313 and the rotating shaft 32. Furthermore, the rotating shaft 32 and the shaft hole can be further strengthened by fixing them, for example by welding, to prevent the rotating shaft 32 from coming off the shaft hole.

[0041] Furthermore, the first buffer portion 312 includes a first end 312a, a second end 312b, and a first curved portion 312c located between the first end 312a and the second end 312b. The first end 312a is connected to the third connecting portion 311, and the second end 312b is connected to the fourth connecting portion 313. The first curved portion 312c creates a height difference between the first end 312a and the second portion 312b in the thickness direction of the first hinge 31. Specifically, as shown in the figure, with... Figure 10 The surface shown is the upper surface of the third connecting part 311. The second end 312b extends away from the first end 312a and bends towards the lower surface of the third connecting part 311, so that the fourth connecting part 313 and the third connecting part 311 are not on the same horizontal plane, forming a height difference between them. Since the third connecting part 311 is fixed, the fourth connecting part 313 can move in the thickness direction of the first hinge 31. Therefore, the above arrangement allows the support member 3 to lift the fourth connecting part 313 to be flush with the third connecting part 311 when rotating. Since the pivot 32 is connected to the fourth connecting part 313, the lifting of the fourth connecting part 313 increases the height of the pivot 32, thereby increasing the distance between the support member 3 and the housing 1. The support member 3 is less likely to interfere with the housing 1 when rotating, which is beneficial for the support member 3 to rotate at a larger angle relative to the housing 1.

[0042] In some embodiments, continue reading Figure 10The fourth connecting portion 313 includes a main body portion 313a and two lugs 313b located at both ends of the main body portion 313a. The lugs 313b are bent relative to the main body portion 313a, so that at least a portion of the lugs 313b protrudes beyond the clearance portion 423. Simultaneously, the lugs 313b are provided with shaft holes, and both ends of the rotating shaft 32 are respectively inserted into the two shaft holes to achieve connection between the rotating shaft and the fourth connecting portion 313. The protrusion of the lugs 313b beyond the clearance portion 423 facilitates the connection between the rotating shaft 32 and the lugs 313b, preventing interference between the rotating shaft 32 and the clearance portion 423. Furthermore, the rotating shaft 32 and the shaft holes can be further reinforced and fixed, for example, by welding, to prevent the rotating shaft 32 from detaching from the shaft holes.

[0043] In some embodiments, the third connecting portion 311 has an arc-shaped structure with a central angle of approximately 150 to 180 degrees. The arc-shaped structure surrounds the first end 312a, and the first curved portion 312 extends in a direction away from the plane where the third connecting portion 311 is located, such that the fourth connecting portion 313 is located outside the semi-enclosed space formed by the arc-shaped structure. In the thickness direction of the first hinge 31, the fourth connecting portion 313 is lower than the third connecting portion 311, that is, the fourth connecting portion 313 is closer to the receiving cavity of the housing 1 than the third connecting portion 311.

[0044] In some embodiments, see Figure 9 and Figure 11 The first connecting part 421 has a C-shaped structure and is welded to the third connecting part 311. The shapes of the first connecting part 421 and the third connecting part 311 are approximately the same, which effectively increases the contact area between them, making the weld more robust. The overall outline of the second rotating part 42 is circular, and the third connecting part 311 protrudes from the first connecting part 421 along the radial direction of the second rotating part 42. Similarly, the overall outline of the third rotating part 43 is also circular, with the first connecting part 421 sandwiched between the third connecting part 311 and the third rotating part 43. The third rotating part 43 is also fixed to the first connecting part 421 by welding. Along the radial direction of the second rotating part 42, the third rotating part 43 protrudes from the first connecting part 421.

[0045] Furthermore, the second connecting portion 422 is sandwiched between the first rotating member 41 and the third rotating member 43. The second connecting portion 422 is provided with a second through hole 424, and the third rotating member 43 is provided with a third through hole 431. The protrusion 411 on the first rotating member 41 passes through the second through hole 424 and the third through hole 431 in sequence, and is fixedly connected to the third rotating member 43, so that the first rotating member 41, the second rotating member 42, and the third rotating member 43 are relatively fixed. At the same time, along the radial direction of the second rotating member 42, the first rotating member 41 protrudes from the second connecting portion 422, and the third rotating member 43 also protrudes from the second connecting portion 422.

[0046] In some embodiments, continue reading Figure 11 The mounting groove 44 includes a first groove 44a and a second groove 44b. The first groove 44a is formed between the portion of the third connecting portion 311 protruding from the first connecting portion 421 and the portion of the third rotating member 43 protruding from the first connecting portion 421. Simultaneously, the second groove 44b is formed between the portion of the first rotating member 41 protruding from the second connecting portion 422 and the portion of the third rotating member 43 protruding from the second connecting portion 422. The first groove 44a and the second groove 44b communicate to jointly form the mounting groove 44, which surrounds the outer periphery of the second rotating member 42. This arrangement ensures a stable connection between the first rotating member 41, the second rotating member 42, and the third rotating member 43. Furthermore, the edges of the first rotating member 41, the third rotating member 43, and the first hinge 31 protrude more than the edge of the second rotating member 42 to form the mounting groove 44. The rotating seat 4 can connect to the housing 1 through the mounting groove and can rotate relative to the housing 1.

[0047] In some embodiments, see Figure 6 and Figure 12 The third rotating component also includes a welding hole 432, the position of which corresponds to the position of the first connecting part 421, and a portion of the first connecting part 421 is exposed through the welding hole 432. By providing the welding hole 432, after the first rotating component 41, the second rotating component 42, and the third rotating component 43 are stacked, since the third rotating component is larger than the second rotating component 42, and the first rotating component 41 and the first hinge 31 obstruct the second rotating component 42, the welding equipment can weld the second rotating component 42 to the side wall of the welding hole 432 through the welding hole 432 to achieve welding and fixing of the second rotating component 42 and the third rotating component 43.

[0048] In some embodiments, see Figure 12 and Figure 13The rotating base 4 also includes a positioning element 45, and the rotating base 4 has a positioning element mounting part 46, in which the positioning element 45 is disposed. When the rotating base 4 rotates relative to the housing 1 at a preset angle, the positioning element 45 can form a limit with the housing 1 to restrict the rotating base 4 from continuing to rotate and to stably hold the rotating base 4 at the preset angle. If the rotating base 4 needs to continue to rotate and move away from the limit point, the user needs to apply more force to the rotating base 4. The setting of the positioning element 45 can make the support of the support member 3 more stable. When the rotating base 4 rotates to the preset angle support, due to the limitation of the positioning element 45, the rotating base 4 will not rotate when the user operates the mobile phone, such as clicking or swiping the screen, which can effectively improve the user experience. Specifically, the positioning component mounting part 46 includes a positioning component mounting groove 461 and a positioning component mounting hole 462. The positioning component mounting groove 461 is recessed in the lower surface of the first rotating component 41, and the positioning component mounting hole 462 is located in the second connecting part 422. Along the thickness direction of the rotating seat 4, the positioning component mounting groove 461 and the positioning component mounting hole 462 communicate to jointly form the positioning component mounting part 46. The positioning component mounting groove 461 mainly functions to install and accommodate the positioning component 45, while the positioning component mounting hole 462 mainly functions to avoid the positioning component 45. The portion of the positioning component 45 located in the positioning component mounting hole 462 can protrude out of the second connecting part 422 to achieve positioning with the mounting part 11a on the side wall of the mounting hole 11. The positioning member 45 is mainly composed of a positioning part that can move within the positioning member mounting part 46 and an elastic member (e.g., a spring) that enables the positioning part to move. The positioning part protrudes from the second connecting part 422 or retracts into the positioning member mounting part 46 by the elastic force of the elastic member, so as to restrict or release the rotation of the rotating seat 4.

[0049] In some embodiments, see Figures 14-16The support member 2 includes a support body 21 and a second hinge 22. The second hinge 22 includes a fifth connecting portion 221, a second buffer portion 222, and a bushing portion 223. The fifth connecting portion 221 is connected to the support body 21, and the connection method can be welding, riveting, bonding, etc. The bushing portion 223 is connected to the rotating shaft 32. The bushing portion 223 is formed by winding the end of the second hinge 22 and can be sleeved on the rotating shaft 32 to achieve connection with the rotating shaft 32. The second buffer portion 222 includes a third end 222a, a fourth end 222c, and a second curved portion 222b located between the third end 222a and the fourth end 222c. The third end 222a is connected to the fifth connecting portion 221, and the fourth end 222c is connected to the bushing portion 223. The second curved portion 222b is bent toward the support body 21 or in a direction away from the support body 21. By providing the second curved portion 222b, when the support body 21 rotates to a certain angle and comes into contact with the surface of the electronic device or its accessories, continued rotation of the support body 21 will cause the second curved portion 222b to undergo elastic deformation. This allows the support body 21 to continue rotating without causing plastic deformation or breakage of the second hinge 22. By bending the second curved portion 222b towards or away from the support body 21, the second buffer portion 222 provides protection against breakage or damage to the second hinge 22. This increases both the rotation angle of the support body 21 and the service life of the second hinge 22. After the force is removed, the second curved portion 222b returns to its pre-deformation state, without affecting the normal support and rotation of the support body 21.

[0050] The above provides a detailed description of a protective shell disclosed in the embodiments of this application. This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand a protective shell and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
