Description

Technical Field

[0002] Currently, widely used foldable screen electronic devices typically consist of a first part and a second part, which are folded and unfolded relative to each other via a hinge structure. To protect the overall electronic device, a protective case needs to be provided, consisting of a first shell and a second shell respectively covering the outer surfaces of the first and second parts, and connected by a connecting structure. This connecting structure is arranged corresponding to the hinge area of ​​the electronic device. However, this type of protective case has the following problems: when the device is folded, the hinge structure is exposed, requiring the connecting structure to completely cover this area; while when the device is fully unfolded, the hinge structure is hidden, and the redundant connecting structure cannot adaptively retract, often pushing the first and second shells outwards. This causes the first shell to extend beyond the outer edge of the first part, and / or the second shell to extend beyond the outer edge of the second part, which not only disrupts the overall appearance consistency but also affects the user's grip and operating experience.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] This application provides a protective case for electronic devices, which is used to cover the outer surface of electronic devices to prevent the outer surface of electronic devices from being scratched and damaged, and to provide cushioning when electronic devices are dropped or collided, thereby reducing the risk of screen breakage and body damage.

[0024] This application provides a protective case for an electronic device, as shown in the reference. Figure 1 to Figure 11The device includes a first housing 1, a second housing 2, and a connector 3. The first housing 1 and the second housing 2 are respectively fitted onto the two foldable parts of an external electronic device. The first housing 1 and the second housing 2 are movably connected to the connector 3. Understandably, the first housing 1 and the second housing 2 are relatively movable, allowing the first housing 1 to have a folded state and an unfolded state relative to the second housing 2, thus adapting to the two relatively rotatable parts of the electronic device. It should be noted that when the first housing 1 and the second housing 2 are in the folded state, the first housing 1 overlaps the second housing 2, and the included angle between them can be 0° or close to 0°. The unfolded state includes fully unfolded and partially unfolded states: when the first housing 1 is fully unfolded relative to the second housing 2, the first housing 1 and the second housing 2 are on the same plane, and the included angle between them is 180°; when the first housing 1 is partially unfolded relative to the second housing 2, the included angle between the first housing 1 and the second housing 2 is between 0° and 180°.

[0025] An elastic mechanism 4 is provided between the first housing 1 and the connecting member 3. The elastic mechanism 4 is connected between the first housing 1 and the connecting member 3 and is used to constrain the relative position between the first housing 1 and the connecting member 3 when the first housing 1 is in different states relative to the second housing 2. When the first housing 1 switches between a folded state and an unfolded state relative to the second housing 2, the elastic mechanism 4 deforms with the relative movement between the first housing 1 and the connecting member 3. For example, when the first housing 1 is in a folded state, the elastic mechanism 4 is in a first state; when the first housing 1 is in an unfolded state relative to the second housing 2, the elastic mechanism 4 is in a second state. The deformation of the elastic mechanism 4 in the first state is greater than its deformation in the second state, or the deformation of the elastic mechanism 4 in the first state is less than its deformation in the second state. variable.

[0026] By setting a first housing 1 and a second housing 2 respectively connected to a connector 3, the first housing 1 and the second housing 2 are respectively used to fit over the two foldable parts of an external electronic device. The connector 3 is set to correspond to the hinge structure of the external electronic device. An elastic mechanism 4 is provided between the first housing 1 and the connector 3 to accommodate the following movements of the external electronic device: when the two relatively rotatable parts of the external electronic device are in a folded state, the hinge structure of the external electronic device is exposed, and at this time, the first housing 1 is folded relative to the second housing 2; when the two relatively rotatable parts of the external electronic device are unfolded relative to each other, the hinge structure of the external electronic device is hidden, and at this time, the first housing 1 is unfolded relative to the second housing 2. To achieve the switching between the folded and unfolded states of the first housing 1 and the second housing 2, the first housing 1 and the connector 3 are connected by the elastic mechanism 4, so that when the two housings switch states, the first housing 1 can be displaced and reset relative to the connector 3. This ensures that whether the electronic device is folded or unfolded, the first housing 1 and the second housing 2 of the protective shell can maintain a good match and fit with the shape of the electronic device, effectively improving the user experience. For example, when the first housing 1 switches from a folded state to an unfolded state relative to the second housing 2, the elastic mechanism 4 rebounds from a state of large deformation to a state of small deformation. The elastic mechanism 4 pulls the two sides of the first housing 1 and the second housing 2, respectively, close to the connector 3, from being far apart to being close together, avoiding misalignment or bulging between the electronic device protective shell and the electronic device due to the connection structure's inability to adapt to the retraction of the pivot structure; thus ensuring that whether the electronic device is folded or unfolded, the first housing 1 and the second housing of the electronic device protective shell remain in a stable position. Both components can maintain a good match and fit with the shape of electronic devices, effectively improving the user experience.

[0027] In one implementation, reference Figure 1 to Figure 3 The first housing 1 includes a first bottom shell 11 and a first frame 12 perpendicularly connected to the outer periphery of the first bottom shell 11, forming a first receiving groove 13 with the first bottom shell 11 and the first frame 12. The second housing 2 includes a second bottom shell 21 and a second frame 22 perpendicularly connected to the outer periphery of the second bottom shell 21, forming a second receiving groove 23 with the second bottom shell 21 and the second frame 22. The first receiving groove 13 and the second receiving groove 23 are respectively used to accommodate two relatively rotatable parts of an external electronic device. The first frame 12 and the second frame 22 correspond to the sidewalls in terms of the thickness of the electronic device. When the two foldable parts of the electronic device are in a folded state, one of the first bottom shell 11 and the second bottom shell 21 corresponds to the back shell (non-display screen) of the electronic device; the other can be a transparent shell, corresponding to the top shell. The housing (display screen or ordinary upper shell). The first frame 12 of the first housing 1 and the second frame 22 of the second housing 2 are respectively movably connected to the connector 3, with the connector 3 located on the side of the first frame 12 away from the first receiving groove 13 and the connector 3 located on the side of the second frame 22 away from the second receiving groove 23. The connector 3 is positioned on the outside of the first frame 12 and the second frame 22 to prevent the connector 3 from obstructing the electronic device and affecting the relative rotation of the first housing 1 and the second housing 2.

[0028] Furthermore, the connector 3 is located on the same side of the first frame 12 and the second frame 22. The first frame 12 has a first opening and is triangular in shape; the second frame 22 has a second opening and is also triangular in shape. The first housing 1 and the second housing 2 have the same shape and size, and when the first housing 1 and the second housing 2 are in the fully extended state, the first opening faces each other and is arranged opposite to each other. Specifically, the first end 121 of the first frame 12 is located at the first opening, and the second end 221 of the second frame 22 is located at the second opening. One end of the connector 3 is movably connected to the first frame 12 near the first end 121, and the other end is movably connected to the second frame 22 near the second end 221. The first frame 12 and the connecting member 3 are provided with an elastic mechanism 4. When the first frame 12 moves relative to the connecting member 3, the elastic mechanism 4 deforms under the action of external force, which can provide the relative movement stroke of the two; at the same time, it has a restoring force to constrain the two to return to the initial position. Under the action of no external force, the first frame 12 and the connecting member 3 do not produce relative movement.

[0029] Therefore, when the first housing 1 and the second housing 2 are fully unfolded, the first end 121 and the second end 221 are positioned opposite each other, and the first housing 1 and the second housing 2 are on the same plane. As the first housing 1 and the second housing 2 gradually rotate from the fully unfolded state to the folded state, the first end 121 and the second end 221 rotate away from each other. When the first housing 1 and the second housing 2 are in the folded state, the first end 121 and the second end 221 are in an up-down distribution.

[0030] In one implementation, such as Figure 4 to Figure 10 As shown, a snap-fit ​​structure 5 is provided between the second housing 2 and the connecting member 3. The snap-fit ​​structure 5 is used to realize the movable connection between the second housing 2 and the connecting member 3. For example, the snap-fit ​​structure 5 includes an elastic buckle 51 and a locking groove 52. The elastic buckle 51 is provided on the second housing 2, and the connecting member 3 is provided with a locking groove. The groove 52; or, the connector 3 is provided with an elastic buckle 51, and the second housing 2 is provided with an engaging groove 52; the elastic buckle 51 and the engaging groove 52 are tightly fitted, and the elastic buckle 51 can rotate within the engaging groove 52. Specifically, the elastic buckle 51 includes a plurality of locking posts 511, which are spaced apart on the second frame 22 along the circumferential direction, forming an internally hollow annular columnar structure; the end of the locking post 511 away from the second frame 22 and located on the outer ring of the annular columnar structure is provided with a protrusion 512, so that the thickness of the end of the locking post 511 away from the second frame 22 is greater than the end of the locking post 511 connected to the second frame 22. The engaging groove 52 is formed by connecting a through hole 521 and a groove 522. The through hole 521 is a circular hole, and the groove 522 is a circular groove. The through hole 521 is located above the groove 522 and is used to engage the groove 522 and the locking post 511. During connection, the locking pin 511 first passes through the through hole 521, and then the protrusion 512 is engaged in the locking groove 522. The size and dimensions of the through hole 521 are perfectly matched to the end of the elastic mechanism 4 connected to the second frame 22; the radial dimension of the locking groove 522 is larger than the radial gear of the through hole 521, so as to limit the displacement of the connector 3 and the second housing 2 along the height direction of the elastic buckle 51. By setting the dimensions of the through hole 521 and the end of the elastic mechanism 4 near the second frame 22 to be the same, the radial displacement of the connector 3 and the second housing 2 along the engagement groove 52 is limited, preventing the elastic buckle 51 from shaking in the engagement groove 52 when the second housing 2 and the connector 3 move relative to each other, and maintaining the fit between the second housing 2 and the external electronic device. The connector 3 includes a base frame 35 and two connecting platforms 36, specifically as follows: Figure 1 , Figure 2 and Figure 11 As shown; the base frame 35 is elongated, and two connecting platforms 36 are arranged opposite each other at the two ends of the base frame 35, and the two connecting platforms 36 are located on the same side of the base frame 35; the base frame 35 is located on the side of the first housing 1 and the second housing 2 that is away from the first receiving groove 13 and the second receiving groove 23, respectively, blocking the gap between the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are in the folded state, the first bottom shell 11 and the second bottom shell 21 are distributed vertically, and the first end of the first frame 12 and the second bottom shell 21 are connected vertically. The second end of the frame 22 is also vertically distributed. At this time, there is no corresponding housing between the first end and the second end, thus shielding the hinge structure of the external electronic device. The size of the base frame 35 matches the size between the first end and the second end when the first housing 1 and the second housing 2 are in the folded state. When the first housing and the second housing 2 switch states, the first end and the second end always move between the electronic device and the base frame 35, which cannot be observed by the user, improving the appearance integrity of the electronic protective case and enhancing its aesthetics.

[0031] Furthermore, two connecting platforms 36 are provided, located opposite each other at both ends of the length of the base frame 35, and protruding on the same side of the base frame 35. Two connecting pieces 3 are provided, located at opposite ends of the length direction of the connection gap between the first housing 1 and the second housing 2, connecting the gap between the first housing 1 and the second housing 2 end to end.

[0032] Each connector 3 is movably connected to the first housing 1 and the second housing 2, respectively. An elastic mechanism 4 is provided between the first housing 1 and each connector 3; similarly, the aforementioned snap-fit ​​structure 5 is provided between the second housing 2 and each connector 3. The elastic mechanism 4 is located between the first housing 1 and the connecting platform 36, and the snap-fit ​​structure 5 is located between the second housing 2 and the connecting platform 36. Between platform 36. In one embodiment, refer to Figure 1 to Figure 4 Provided that the other structures are consistent with those mentioned above, the elastic mechanism 4 includes a spring 41 and a protrusion 42; the protrusion 42 is provided on the first housing 1, and the connecting member 3 is provided with a mounting groove 31 that mates with the protrusion 42, or the protrusion 42 is provided on the connecting member 3, and the first housing 1 is provided with a mounting groove 31 that mates with the protrusion 42; one end of the spring 41 is sleeved on the outside of the protrusion 42, and the other end is connected to the mounting groove 31.

[0033] Specifically, a protruding post 42 is provided on the first frame 12 of the first housing 1. The protruding post 42 is, for example, a cylindrical structure. The radial dimension of the mounting groove 31 is larger than the radial dimension of the protruding post 42, so that the protruding post 42 can be displaced along the radial direction of the mounting groove 31. When the first housing 1 and the second housing 2 switch between a folded state and an unfolded state, the protruding post 42 moves radially along the mounting groove 31. A spring 41 is sleeved on the outer peripheral sidewall of the protruding post 42, and both the spring 41 and the protruding post 42 are accommodated within the mounting groove 31. One end of the spring 41 is connected to the connector 3, so that when the protruding post 42 moves within the mounting groove 31, the spring 41 always constrains the movement of the protruding post 42. When the first housing 1 and the second housing 2 are in a folded state, the protruding post 42 deviates from the center position of the mounting groove 31, and the spring 41 always provides a restoring force to the protruding post 42, driving the protruding post 42 to move towards the center of the mounting groove 31. When the first housing 1 and the second housing 2 are in their fully extended state, the protrusion 42 is located at the center of the mounting groove 31, and the spring 41 is in its natural state, or the deformation it produces is less than the deformation of the spring 41 when the protrusion 42 is deviated from the center of the mounting groove 31. Therefore, the elastic mechanism enables the first housing 1 and the second housing 2 to move relatively away from each other, and to move closer together after moving relatively away.

[0034] Spring 41 can be a helical spring, a spiral spring, etc.; taking a spiral spring as an example, the inner ring of the spiral spring is sleeved on the outside of the protrusion 42, and the side wall of the mounting groove 31 is provided with an annular snap-fit ​​groove 32, and the outer ring of the spiral spring is snapped into the snap-fit ​​groove 32.

[0035] The spiral spring is sleeved on the outside of the protrusion 42. Under the restriction of the spiral spring, the protrusion 42 can not only move easily in the mounting groove 31, but the spiral spring also effectively restricts the movement of the protrusion 42. Compared with other springs 41, the assembly between the spiral spring, the protrusion 42, and the mounting groove 31 is simpler, and the movement of the protrusion 42 is more free.

[0036] Furthermore, the connecting platform 36 includes a base frame 361 integrally formed with the aforementioned base frame 35, and a fixing piece 362; the base frame 361 has a slot, and the fixing piece 362 is located in the slot to facilitate the production and assembly of the connector 3. The base frame 361 has a first through hole, which is the aforementioned through hole 521, and the fixing piece 362 has a corresponding slot 522. The first through hole 521 and the slot 522 are respectively used for the assembly and engagement of the elastic buckle 51. The base frame 361 also has a second through hole, and the fixing piece 362 has a slot connected to the second through hole. The second through hole and the slot are connected to form a mounting groove 31, and the protrusion 42 is located in the mounting groove 31. The snap-fit ​​groove 32 is located on the side of the fixing piece 362 near the first housing 1. The snap-fit ​​groove 32 and the corresponding wall of the base frame 361 are connected to form an annular groove. The radial dimension of the snap-fit ​​groove 32 is larger than that of the mounting plate. The radial dimension of the mounting slot 31. For the aesthetics of the electronic device protective case, a mounting piece is also provided on the side of the fixing piece 362 away from the first housing 1 to cover the elastic mechanism 4 and the snap-fit ​​structure 5, etc.

[0037] In another implementation, such as Figure 5 and Figure 6 As shown, the elastic mechanism 4 includes multiple elastic posts 43; the multiple elastic posts 43 are spaced apart on the first housing 1 along the circumferential direction, and the end of the elastic post 43 away from the first housing 1 is provided with a latching part 431. The connecting member 3 is provided with a latching groove 33, and each latching part 431 is engaged in the latching groove 33. Alternatively, the multiple elastic posts 43 are spaced apart on the connecting member 3 along the circumferential direction, and the end of the elastic post 43 away from the connecting member 3 is provided with a latching part 431. The first housing 1 is provided with a latching groove 33; the elastic posts 43 can deform in the latching groove 33, and each latching part 431 is engaged in the latching groove 33. The elastic mechanism 4 deforms to provide relative displacement between the connecting member 3 and the first housing 1 and to return to its original position.

[0038] For example, multiple elastic pillars 43 protrude circumferentially from the first frame 12 of the first housing 1. The multiple elastic pillars 43 form a spatial annular columnar structure. A latching portion 431 is provided at the end of the elastic pillar 43 away from the first housing 1 and located on the outer side of the annular columnar structure; this makes the end of the elastic pillar 43 connected to the first housing 1 thinner than the end of the elastic pillar 43 away from the first housing 1. The radial direction of the latching groove 33 near the first housing 1 is smaller than the radial direction of the end of the latching groove 33 away from the first housing 1; and the radial dimension of the latching groove 33 near the first housing 1 is larger than the radial dimension of the annular columnar structure, so that the latching portion 431 engages with the end of the latching groove 33 away from the first housing 1. The end of the elastic pillar 43 near the first housing 1 can move radially within the latching groove 33, causing the elastic pillar 43 to deform. When the first housing 1 and the second housing 2... When in the folded state, the end of the elastic column 43 away from the first housing 1 deforms; when the first housing 1 and the second housing 2 switch from the folded state to the unfolded state, the elastic column 43 gradually returns to its original shape.

[0039] In another implementation, refer to Figure 7 to Figure 10 The elastic mechanism 4 includes a guide post 44, a mating part 45, and a deformation structure 46; the connecting part 3 has a protruding post 42, and the first housing 1 has an assembly groove 34 corresponding to the position of the protruding post 42, or the first housing 1 has a protruding post 42, and the connecting part 3 has an assembly groove 34 corresponding to the position of the protruding post 42; the mating part 45 is located in the middle of the assembly groove 34, and the deformation structure is located on the outer periphery of the mating part 45, with the end of the deformation structure away from the mating part 45 connected to the groove wall of the assembly groove 34; the protruding post 42 and the mating part 45 are mated and connected to drive the mating part 45 to move together.

[0040] For example, the connector 3 has a guide post 44 protruding from the side near the first housing 1, and the first housing 1 has an assembly groove 34 on the side corresponding to the guide post 44. A mating part 45 is located in the middle of the assembly groove 34, for example, at the center. A deformation structure 46 is provided on the outer circumferential side of the mating part 45, connecting the groove wall of the assembly groove 34 to the mating part 45. The guide post 44 and the mating part 45 are connected, for example, by snap-fit ​​or adhesive bonding. The guide post 44 can drive the mating part 45 to move together. Due to the deformation structure 46, the mating part 45 can move within the assembly groove 34 under the drive of the guide post 44. For example, the mating part 45 is a tubular structure with a guide hole 451 penetrating its center. The guide hole 451 fully engages with the guide post 44, and the guide post 44 is inserted into the guide hole 451. The movement of the guide post 44 drives the mating part 45 to move together.

[0041] When the connector 3 moves relative to the first housing 1, the guide post 44 drives the mating part 45 to move, and the deformation structure 46 can deform and return to its original shape; so that when the first housing 1 and the second housing 2 are in the folded state, the mating part 45 deviates from the center position of the assembly groove 34, and the deformation structure 46 deforms; when the first housing 1 and the second housing 2 are in the fully unfolded state, the mating part 45 returns to the center position of the assembly groove 34.

[0042] Deformation structure 46 includes, for example, multiple deformation plates 461, specifically as follows: Figure 7 and Figure 8 As shown, the deformation piece 461 is constructed to form an arcuate portion, and multiple deformation pieces 461 are spaced apart on the circumferential outer side of the mating part 45. The side of the deformation piece 461 away from the mating part 45 is connected to the assembly groove 34; or, the deformation structure 46 includes the deformation piece 461, specifically as shown in the figure. Figure 9 and Figure 10 As shown, the deformation piece 461 is in the shape of annular pleats. The inner ring of the deformation piece 461 is fitted around the outer circumference of the mating part 45, and the outer ring of the deformation piece 461 is connected to the assembly groove 34. Here, the deformation structure 46 is not uniquely defined.

[0043] In other embodiments, the aforementioned elastic mechanism 4 may also be provided between the second housing 2 and the connector 3. The elastic mechanism 4 replaces the above-mentioned snap-fit ​​structure 5, but is not limited here.

[0044] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. All equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
