Some specific embodiments of the present disclosure will be described in detail below with reference to the drawings.

The protective casing structure consistent with the embodiments of the present disclosure is used for loading an electronic. In the following embodiments of the present disclosure, unless otherwise specified, the electronic device is specifically described by taking a camera and a gimbal as an example. FIG. 1 is a schematic diagram of a protective casing structure consistent with embodiments of the disclosure. As shown in FIG. 1, the protective casing structure includes a casing 10 and a hood assembly 20. One end of the casing 10 is provided with an opening adapted to a shape of a hood of the hood assembly 20. The opening and the hood abut against each other. The casing 10 and the hood assembly 20 can be locked with each other to form a sealed cavity. The sealed cavity is provided with a mounting member for mounting the electronic device, and the sealed cavity is provided with an activity space for the electronic device.

As shown in FIG. 1, the protective casing structure includes a fastener 30. The casing 10 and the hood assembly 20 are locked to each other by the fastener 30. In some embodiments, the fastener 30 may also be an integral structure with the casing 10 or the hood assembly 20. That is, the fastener 30 may be a fastening member included in one of the casing 10 and the hood assembly 20. The other one of the casing 10 and the hood assembly 20 is provided with a fastener fitting member that cooperates with the fastening member. The fastening member cooperates with the fastener fitting member to realize a fastening connection between the casing 10 and the hood assembly 20. For example, the fastening member and the fastening fitting member may correspond to a threaded structure or a buckle structure.

FIG. 2 is a schematic diagram of the protective casing structure without the hood assembly 20 consistent with embodiments of the disclosure. As shown in FIG. 2, the protective casing structure further includes a loading assembly 40 for mounting the electronic device. The loading assembly 40 is arranged in the sealed cavity. The loading assembly 40 includes at least one fixed loading member detachably connected with the mounting member. In some embodiment, the loading assembly 40 may be connected to the mounting member by a manner, for example, gluing, snapping, or screwing, to cause the gimbal and the camera as a whole to be stably mounted in the sealed cavity.

FIG. 3 is another schematic diagram of the protective casing structure consistent with embodiments of the disclosure. As shown in FIG. 3, the protective casing structure further includes a key assembly 50. The casing 10 may further provided with a key mounting member. The key assembly 50 may be mounted at the key mounting member.

FIG. 4 is an exploded view of the protective casing structure in FIG. 3. As shown in FIG. 4, the protective casing structure further includes a sealing member 60 arranged at an abutment between the casing 10 and the hood assembly 20. After the casing 10 and the hood assembly 20 are locked to each other, the casing 10 and the hood assembly 20 compress the sealing member 60, thereby achieving an effect of sealing, waterproof, and dustproof.

As shown in FIG. 4, the hood assembly 20 includes a see-through member 21 and a support 22. The see-through member 21 may be provided with a see-through unit facing the electronic device loaded in the sealed cavity. The support 22 includes an inner cavity that penetrates the support 22. One end of the inner cavity is fixed with the see-through member 21, and another end is used as the hood to abut the opening of the casing 10. The support 22 is fastened connected to the casing 10 through the fastener 30. In some embodiments, the see-through member 21 can include a glass member or a member made of another transparent material. The see-through member 21 can be fixed at the support 22 by snapping or gluing. A sealing ring can also be provided between the see-through member 21 and the support 22. In an example embodiment, a size of the see-through member 21 depends on a movement range provided by the gimbal to the camera and a field of view of a lens of the camera, which is specifically based on a scene with a maximum angle that the camera can capture. The see-through member 21 may be flat or dome shaped.

In some embodiments, the see-through member 21 and the support 22 may also be an integral structure, as long as transparency and strength are ensured.

In some embodiments, the fastener 30 described in the above embodiments may include a locking ring. Two ends of the locking ring are connected to the casing 10 and the support 22, respectively. The casing 10 and the support 22 are adaptively matched with the shape of the locking ring. For example, the support 22 is configured as a cylindrical structure, and the shape of the casing 10 is configured as a trumpet shape. In some embodiments, the support 22 and the casing 10 may be configured as structures with different shapes. For example, the support 22 may also be configured as a prismatic structure, or a special-shaped structure, etc.

FIG. 5 is a cross-sectional view of the protective casing structure in FIG. 3. FIG. 6 is an enlarged schematic diagram of part A in FIG. 5. As shown in FIGS. 5 and 6, in an axial direction of the locking ring, one end of an inner wall of the locking ring is provided with an inner thread 31, and another end of the inner wall of the locking ring is provided with an inner boss 32. An outer wall of the casing 10 is provided with an outer thread 101. The outer wall of the support 22 is provided with an outer boss 201. After the casing 10 and the support 22 are locked by the locking ring, a threaded connection is formed between the inner thread 31 and the outer thread 101, and the inner boss 32 is clamped with the outer boss 201. In some embodiments, the outer thread 101 can also be provided at the outer wall of the support 22, and the outer boss 201 is provided at the outer wall of the casing 10. In an example embodiment, the inner thread 31 and the outer thread 101 include thread structures with self-locking function. Because of the self-locking thread, after the support 22 and the casing 10 are locked, a relative position between the support 22 and the casing 10 cannot be changed. A compression amount of the sealing member 60 provided between the support 22 and the casing 10 may be maintained at a stable value, thereby achieving a reliable sealing effect. In an example embodiment, the hood assembly 20 has both easy disassembly and waterproof reliability by using a waterproof means of the self-locking thread and the sealing ring. The deep-water imaging can also be achieved by using a material with a high compression resistance to make the hood assembly 20 and the casing 10.

Further, in an example embodiment, as shown in FIG. 6, on the outer wall of the support 22 provided with the outer boss 201, a first connecter 202 is further provided adjacent to the outer boss 201. The inner wall of the locking ring is also provided with a second connecter 320. The first connecter 202 cooperates with the second connecter 320 to realize the connection of the locking ring with the casing 10 or the support 22, and to provide guidance for a movement of the locking ring. In some embodiments, the first connecter 202 may include a convex ring arranged along a circumferential direction of the support 22, while the second connecter 320 includes a concave ring arranged along the circumferential direction of the locking ring, Alternately, the first connecter 202 may include the concave ring arranged along the circumferential direction of the support 22, while the second connecter 320 includes the convex ring arranged along the circumferential direction of the locking ring. The concave ring and the convex ring are engaged with each other. The movement of the locking ring includes a rotational movement relative to the support 22, a rotational movement relative to the casing 10, and a linear movement. When the locking ring performs a rotational movement, the convex ring cooperates with the concave ring to provide guidance. When the outer boss 201 is arranged at the casing 10, the first connecter 202 is located at the outer wall of the casing 10 correspondingly. In an example embodiment, the second connecter 320 is arranged at the inner boss 32.

FIG. 7 is a sectional exploded view of the support 22 and the casing 10 in FIG. 6. As shown in FIG. 7, one end of the support 22 facing the casing 10 is provided with a groove 203 surrounding the hood. After the hood abuts against the opening, the casing 10 is partially inserted into the groove 203. Groove walls 203a, 203b of the groove 203 are attached to a portion where the casing 10 is inserted. This insertion method can improve a degree of sealing of the sealed cavity formed by the connection between the casing 10 and the hood assembly 20. Further, the portion where the casing 10 is inserted and a bottom of the groove 203 form an accommodation cavity. The sealing member 60 is arranged in the accommodation cavity no matter whether the hood assembly 20 is removed from the casing 10 or not, to prevent the sealing member 60 from being exposed to a greatest extent, to reduce a probability of the sealing member 60 being damaged, and to provide an accommodation space for the sealing member 60. The sealing member 60 can be stably accommodated in the accommodation cavity under an action of an elasticity of the sealing member 60, thereby preventing the sealing member 60 from frequently dropping during a process to assemble and disassemble the casing 10 and the support 22.

In some embodiments, one end of the casing 10 facing the support 22 may be provided with a step structure surrounding the opening. A convex 10a of the step structure is inserted into the groove 203, and the convex 10a is attached to the groove walls 203a, 203b of the groove 203. A concave 10b of the step structure forms an avoidance groove for a groove edge of the groove 203. Therefore, the degree of sealing of the sealed cavity can be improved. Further, another accommodation cavity is formed between the convex 10a of the step structure and the bottom of the groove 203. The sealing member 60 is arranged in the other accommodation cavity.

In some embodiments, the groove 203 may be provided at the one end of the casing 10 facing the support 22. Furthermore, the step structure may be arranged at the one end of the support 22 facing the casing 10.

In an example embodiment, as show in FIG. 4, an inner wall of the sealed cavity is symmetrically provided with a first mounting member 102 and a second mounting member (not shown). The loading assembly 40 correspondingly includes a first fixed loading member 41, a second fixed loading member 42, and a movable loading member 43 for loading the electronic device. The first fixed loading member 41 and the second fixed loading member 42 cooperate to clamp the movable loading member 43. The first fixed loading member 41, the second fixed loading member 42, and the movable loading member 43 are combined to form a mounting space for the electronic device. The first fixed loading member 41 is fixed to the first mounting member 102, while the second fixed loading member 42 is fixed to the second mounting member. In an example embodiment, a size of the mounting space can be adjusted by adjusting the relative positions between the movable loading member 43 and the first fixed loading member 41, and between the movable loading member 43 and the second fixed loading member 42, to adapt to the mounting of electronic devices with various shapes and sizes. In some embodiments, the first fixed loading member 41 and the second fixed loading member 42 are provided with a first sliding groove 411 (not shown) and a second sliding groove (not shown), respectively. The movable loading member 43 can be slid in or out of the first sliding groove 411 and the second sliding groove, to realize the loading and removing of the electronic device.

FIG. 8 is a schematic exploded structural diagram of the loading assembly 40 consistent with the embodiments of the disclosure. As shown in FIG. 8, the movable loading member 43 includes a first elastic edge 431 and a second elastic edge 432. At least one of the first elastic edge 431 or the second elastic edge 432 is provided with a convex point 433. When the movable loading member 43 is slid into the first sliding groove 411 and the second sliding groove, after the convex point 433 is pressed, the first elastic edge 431 and the second elastic edge 432 may be deformed. After the movable loading member 43 is slid into the first sliding groove 411 and the second sliding groove, the convex point 433 is engaged with concave points 412 provided in the first sliding groove 411 and the second sliding groove, to enable the first fixed loading member 41 and the second fixed loading member 42 to lock the movable loading member 43 jointly. In this scenario, the first elastic edge 431 and the second elastic edge 432 return to original states thereof.

In an example embodiment, as shown in FIG. 4, a third mounting member 103 is further provided at the wall of the sealed cavity. The loading assembly 40 further includes a third fixed loading member 44. The third fixed loading member 44 is mounted at the third mounting member 103, to assist the locking of the electronic device after the electronic device is loaded into the sealed cavity. In an example embodiment, the first fixed loading member 41, the second fixed loading member 42, and the third fixed loading member 44 are specifically arranged at different sides of the movable loading member 43.

In an example embodiment, a lower portion of the movable loading member 43 includes a soft rubber structure 434. When the movable loading member 43 clamps a gimbal arm of the gimbal, the shape of the soft rubber structure 434 fits the gimbal arm. Under the action of the movable loading member 43 and the casing 10, the gimbal and the camera as a whole can be stably loaded in the sealed cavity. Because the camera is movable in the casing 10, and the entire loading assembly 40 is outside of the movement range of the camera, which may not interfere with the movement of the gimbal and the camera. Therefore, the sealed cavity can reliably fix the gimbal and the camera in the casing 10 while meeting a requirement of the movement range of the camera. The entire loading assembly 40 has advantages of simple structure and reliable mounting.

That is, the sealing ring 54 is arranged in a space formed by a cooperation of the first convex ring 11 and the sealing cover 55. The pressing shaft 522 sequentially passes through the resetting member 53, the sealing cover 55, the sealing ring 54, and the through hole 104.

In some embodiments, the end cap 521 is provided through the through hole of the package 51. The edge of the end cap 521 is provided with a limiting flange 5211 that abuts against the package 51. The limiting flange 5211 and the sealing cover 55 or the casing 10 jointly limit a movement range of the pressing shaft 522 to prevent the pressing shaft 522 from damaging the keys of the gimbal or another electronic device due to excessive stroke.

In some embodiments, a part of the package 51 away from the casing 10 is made of a soft material. The end cap 521 abuts against the soft material part of the package 51. The soft material part of the package 51 and the sealing cover 55 or the casing 10 jointly limit the movement range of the pressing shaft 522 to prevent the pressing shaft 522 from damaging the keys of the gimbal or another electronic device due to excessive stroke.

In some embodiments, the key mounting member further includes a second convex ring 12 arranged around the first convex ring 11. The sealing cover 55 is located between the first convex ring 11 and the second convex ring 12. The package 51 is mutually connected with a snap 13 provided at the inner wall of the second convex ring 12. In some embodiments, another sealing ring may also be provided between the package 51 and the second convex ring 12.

In some embodiments, the key assembly 50 includes at least two sets of the pressing member 52, the resetting member 53, and the sealing assembly.
