As shown in fig. 1 and 2, a housing assembly 100 of a photographing apparatus includes: the assembly main body 10, the rotation member 20 and the catch 30. The mounting body 10 is used to mount a lens module (not shown) of a photographing apparatus. The fitting body 10 includes a first end wall 11 and an insert portion 12 connected to the first end wall 11, and the insert portion 12 includes a second end wall 121 opposite to the first end wall 11, and a side wall 122 extending between the first end wall 11 and the second end wall 121. The rotating member 20 is rotatably mounted on the assembly body 10, and the rotating member 20 extends through the first end wall 11 to the second end wall 121 and is in limit fit with the first end wall 11.

The catch 30 is connected to the rotating member 20 and is located at a portion of the rotating member 20 that passes over the first end wall 11. The catch 30 includes a stowed position in which the catch 30 is stowed outside the side wall 122 of the insert 12 and an extended position. In the deployed position, the catch 30 extends away from the side wall 122. When the rotating member 20 rotates, the retaining member 30 is driven to switch between the retracted position and the extended position, and the relative position between the retaining member 30 and the rotating member 20 is adjusted to change the distance between the retaining member 30 and the first end wall 11.

The assembly body 10 is a thin-walled structural member, which may be an integral structure or a metal member. The embedded portion 12 protrudes from the first end wall 11 in a convex shape, the second end wall 121 and the sidewall 122 surround to form the accommodating space 13, and the first end wall 11 is disposed at an open end of the accommodating space 13 of the embedded portion 12 in a flange shape. The accommodating space 13 is used for mounting accessories such as the lens module 200 and the like to constitute the photographing apparatus. The first end wall 11 and the second end wall 121 are oppositely arranged at two ends of the side wall 122, and the outer contour size of the first end wall 11 is larger than that of the second end wall 121. The fitting portion 12 is fitted into an installation site such as a ceiling, and the first end wall 11 is fixed to the outside of the installation site. In an alternative embodiment, the second end wall 121 is closed at one end of the side wall 122, and the edge of the second end wall 121 intersects the side wall 122 through a circular arc, so that the bottom space of the accommodating space 13 is closed and the sealing performance is good. In an alternative embodiment, the second end wall 121 and the first end wall 11 are respectively disposed at two ends of the side wall 122, and the second end wall 121 and the first end wall 11 are both flange-shaped to protrude out of the side wall 122, so that two ends of the rotating member 20 are respectively defined at the first end wall 11 and the second end wall 121, and the connection of the rotating member 20 is facilitated. The second end wall 121 is closed at one end of the side wall 122, or shields a part of the opening of the surrounding area of the side wall 122, so as to form a semi-closed structure. In an alternative embodiment, the sidewall 122 has a circular, rectangular, or other annular cross-section.

One end of the rotation member 20 passes through the first end wall 11 and extends toward the second end wall 121 until the other end of the rotation member 20 is defined at the first end wall 11. The holder 30 is screw-coupled with the rotating member 20, and the rotating member 20 can rotate relative to the assembly body 10 by a rotational force so that the holder 30 moves or rotates within a range between the first end wall 11 and the free end of the rotating member 20.

When the rotating member 20 rotates about its own rotation axis, the catch 30 rotates with the rotating member 20 and adjusts the deployment angle with respect to the assembly main body 10 or the interval between the first end walls 11. Wherein the catch 30 stops rotating with the rotating member 20 when rotating and abutting against the fitting body 10, thereby being in the unfolded position or the folded position. Also, the rotating member 20 is screw-coupled to the catch 30, and the catch 30 slides in a direction approaching or separating from the first end wall 11 under the driving of the rotating member 20 to adjust the distance between the catch 30 and the first end wall 11. When the retainer 30 is in the extended position and moves toward the first end wall 11, the first end wall 11 and the retainer 30 are clamped together at two sides of the installation site to complete the clamping and installation of the enclosure assembly 100 to the installation sites with different thicknesses. For example, the housing assembly 100 is inserted into the mounting hole 301 of the ceiling 300 when the retainer 30 is in the collapsed position, as shown in fig. 3 and 4, until the first end wall 11 abuts against the lower surface of the ceiling 300. The rotating member 20 rotates to rotate the catch 30 with the rotating member 20 from the retracted position to the extended position, and the catch 30 moves toward the ceiling 300 and is engaged with the ceiling 300 under the continuous rotation of the rotating member 20, so that the housing assembly 100 is mounted on the ceiling 300, and the assembly is convenient.

The holder 30 of the housing assembly 100 of the photographing apparatus rotates along with the rotation of the rotation member 20 to be in the unfolded position or the folded position, and the mounting and dismounting of the housing assembly 100 and the mounting portion such as the ceiling can be achieved by the rotation member 20 and the holder 30 of the housing assembly 100, so that an additional embedded bracket may not be required, and thus, the assembly is convenient and simple. And the rotating member 20 is rotated to adjust the relative position of the retainer 30 and the rotating member 20 to change the distance between the retainer 30 and the first end wall 11, so that the housing assembly 100 is adapted to installation parts such as ceilings with different thicknesses, and the assembly flexibility is good.

The catch 30 extends in the direction of extension of the side wall 122 when in the stowed position. In some embodiments, the catch 30 abuts against the outer surface of the side wall 122 when in the closed position, so that the catch 30 can pass through the mounting hole 301 of the ceiling 300 together with the embedded part 12 and the outer size of the housing assembly 100 can be reduced. When the embedded part 12 is inserted into the mounting hole 301, the retainer 30 extends along the extending direction of the side wall 122, so that the size of the opening of the mounting hole 301 can be reduced, and the structural damage area to the panels such as the ceiling 300 can be reduced. The free end of the catch 30 is away from the side wall 122 when the catch 30 is in the deployed position and forms a clamping space with the first end wall 11.

In an embodiment, a rotation limiting portion 124 is disposed outside the side wall 122, and an extending direction of the rotation limiting portion 124 intersects with a surrounding direction of the side wall 122. When the retaining member 30 moves from the retracted position to the extended position, the retaining member 30 rotates to the extended position along with the rotation of the rotating member 20 until it abuts against the rotation limiting portion 124, and moves toward the first end wall 11 along with the continued rotation of the rotating member 20.

The sidewall 122 is annular in configuration to form an annular thin-walled structure. The rotation-limiting portion 124 extends from the first end wall 11 toward the second end wall 121 to intersect the surrounding direction of the side wall 122. When the holding member 30 moves from the folded position to the unfolded position, the rotation-limiting portion 124 is located in the rotation direction of the holding member 30 to limit the unfolded angle of the holding member 30. Optionally, the rotation-limiting portion 124 is configured as a rib protruding out of the surface of the sidewall 122 or an inclined surface bending relative to the sidewall 122, so that the retaining member 30 rotates relative to the sidewall and abuts against the rotation-limiting portion 124, and is located at the unfolding position, which is convenient to set. The rotation restricting portion 124 forms an undulated plane with respect to the side wall 122, and can reinforce the overall strength of the side wall 122 and maintain the shape stability.

In an alternative embodiment, as shown in fig. 3 and 4, the maximum circle of circumscribed of the horizontal projection of the embedded portion 12 is smaller than the maximum circle of circumscribed of the horizontal projection of the first end wall 11, the catch 30 is within the range of the maximum circle of circumscribed of the horizontal projection of the embedded portion 12 when in the stowed position, and the catch 30 extends beyond the maximum circle of circumscribed of the horizontal projection of the embedded portion 12 when in the deployed position.

The horizontal projection is a forward projection to the horizontal plane. The first end wall 11 and the second end wall 121 are vertically separated, and the first end wall 11 and the second end wall 121 may extend horizontally or substantially horizontally. The fitting body 10 is orthographically projected toward a horizontal plane, and the horizontal projection of the fitting portion 12 on the horizontal plane has a projected contour line of the horizontal projection of the fitting portion 12 within the maximum circumscribed circle of the fitting portion 12. The projection contour of the insertion portion 12 is a circle, a polygonal surface, a polygon, or an irregular shape. The horizontal projection of the first end wall 11 in the horizontal plane has a projected contour line of the horizontal projection of the first end wall 11 which lies within the maximum circumcircle of the first end wall 11. The maximum circumcircle of the insert 12 is smaller than the maximum circumcircle of the first end wall 11 so that the first end wall 11 can limit the depth of the insert 12 into the wall.

When the retaining member 30 is in the folded position, it is located within the maximum circumscribed circle of the horizontal projection of the embedding portion 12, so that the aperture of the mounting hole 301 is slightly larger than the maximum circumscribed circle of the embedding portion 12, and the mounting assembly main body 10 can be mounted, and has small opening size, small fit clearance and high mounting precision. The retainer 30 extends beyond the maximum circumscribed circle of the horizontal projection of the embedding portion 12 in the unfolding position, the retainer 30 is driven by the rotating member to rotate to be in the unfolding position, so that the retainer 30 is arranged opposite to the first end wall 11 to form a clamping space, and the retainer 30 has high clamping strength and small deformation.

As shown in fig. 5 and 6, in an embodiment, the embedded portion 12 includes a protruding portion 123 located between the side wall 122 and the first end wall 11, and a maximum circumscribed circle of a horizontal projection of the protruding portion 123 is larger than a maximum circumscribed circle of a horizontal projection of the side wall 122. The holding member 30 is located within the maximum circumscribed circle of the horizontal projection of the protrusion 123 in the folded position, and the holding member 30 extends beyond the maximum circumscribed circle of the horizontal projection of the protrusion 123 in the unfolded position.

The second end wall 121, the projection 123 and the first end wall 11 constitute a stepped structure, and the boss portion 123 is located between the first end wall 11 and the second end wall 121 and intersects the side wall 122. The maximum circumscribed circle of the horizontal projection of the protrusion 123 is larger than the maximum circumscribed circle of the horizontal projection of the sidewall 122 to improve the mounting convenience of the insertion part 12. When the embedded part 12 is installed in the installation hole 301, the protruding part 123 is matched with the hole wall of the installation hole 301, the maximum circumcircle of the horizontal projection of the side wall 122 is smaller than the size of the installation hole 301, and the installation is convenient.

The retaining member 30 is located within the maximum circumscribed circle of the protrusion 123 in the folded position, and the retaining member 30 extends beyond the maximum circumscribed circle of the horizontal projection of the protrusion 123 in a direction away from the side wall 122 in the unfolded position. The size of the mounting hole 301 is greater than or equal to the maximum circumscribed circle size of the horizontal projection of the protrusion 123 and smaller than the maximum inscribed circle size of the first end wall 11, so that the holding member 30 and the first end wall 11 together hold the fixed housing assembly 100 for convenient assembly.

The mounting size of the housing assembly 100 when the retainer 30 is in the collapsed position is minimized to facilitate mounting and securing of the housing assembly 100. In one embodiment, the assembly body 10 includes a receiving groove 14 recessed into the embedding portion 12, a horizontal projection of the catch 30 in the collapsed position is at least partially within the horizontal projection of the receiving groove 14, and a horizontal projection of the catch 30 in the expanded position exceeds the horizontal projection of the receiving groove 14. The receiving groove 14 is a groove structure formed on the surface of the inserting portion 12, and the rotating member 20 extends into the receiving groove 14, so that the rotating portion of the retaining member 30 connected to the rotating member 20 is located in the receiving groove 14, thereby reducing the size of the protruding sidewall 122 of the retaining member 30. The retainer 30 is positioned in the receiving groove 14 in the collapsed position such that the retainer 30 is partially or entirely positioned in the receiving groove 14, reducing the profile size of the housing assembly 100 in the cross-section where the retainer 30 is located. The receiving groove 14 extends from the first end wall 11 toward the second end wall 121 so that the retainer 30 can move along the wall of the receiving groove 14 in the closed position and maintain a minimum installation size. Wherein, the extension range of the receiving groove 14 is less than or equal to the distance between the first end wall 11 and the second end wall 121.

In an alternative embodiment, the receiving groove 14 includes a first groove wall 141 and a second groove wall 142, and the first groove wall 141 extends from the side wall 122 to the inside of the embedding portion 12 in the surrounding direction of the side wall 122 of the assembling body 10. The second slot wall 142 extends from the first slot wall 141 to the outside of the embedded portion 12, the retaining member 30 extends along the extending direction of the first slot wall 141 in the folded position, the rotation limiting portion 124 includes the second slot wall 142, and the retaining member 30 abuts against the second slot wall 142 in the unfolded position.

The first groove wall 141 extends toward the interior of the embedding portion 12, so that the retaining member 30 is at least partially located in the receiving groove 14 when abutting against the first groove wall 141, thereby reducing the size of the protruding side wall 122 of the retaining member 30. The curved second groove wall 142 is an embodiment of the rotation limiting portion 124, and the second groove wall 142 extends from the first groove wall 141 to the outside of the insertion portion 12 to form a curved surface with an inclined angle or different curvature radii. The retaining member 30 abuts against the second slot wall 142 to be in the extended position. The inclined angle between the first groove wall 141 and the second groove wall 142 is adjusted to adjust the extended position of the retainer 30. In an alternative embodiment, a right angle or an obtuse angle is formed between the first groove wall 141 and the second groove wall 142, and the included angle between the first groove wall 141 and the second groove wall 142 is adjusted to adjust the expanded position and the collapsed position of the retaining member 30. The retaining member 30 abuts against the first groove wall 141 to be in the closed position. In an alternative embodiment, the receiving groove 14 is opened from the first end wall 11 to the second end wall 121, so that the retainer 30 can move in a range between the first groove wall 141 and the second groove wall 142 and maintain the closed position.

In one embodiment, as shown in fig. 7, the second slot wall 142 extends beyond the side wall 122 toward the embedding portion 12 to enlarge the contact area between the retaining member 30 and the second slot wall 142. The second channel wall 142 extends outwardly beyond the side wall 122 and forms a rib structure at the distal end that reinforces the structural strength of the insert 12. In an alternative embodiment, the end of the second groove wall 142 is used to limit the rotation angle of the retaining member 30, and the adjustment effect is good. For example, the side wall 122 is approximately a cylindrical or truncated-cone-shaped curved surface, and the receiving groove 14 is partially recessed from the surface of the side wall 122. The second groove wall 142 of the accommodating groove 14 protrudes outward along the radial line of the side wall 122, or the second groove wall 142 of the accommodating groove 14 forms an acute angle with the radial line of the side wall 122, so as to adjust the extending angle of the retaining member 30 at the extending position where the retaining member abuts against the second groove wall 142.

As shown in fig. 7 and 8, in an embodiment, the second groove wall 142 extends toward the second end wall 121 beyond the second end wall 121 to enlarge the range of motion of the catch 30 in the extended position, and the holding and mounting range of the housing assembly 100 is large. The second groove wall 142 extends from the first end wall 11 toward the second end wall 121 and beyond the second end wall 121 to form a rib structure. The rotating member 20 is located in the receiving groove 14 and protrudes from the second end wall 121 along the extending direction of the receiving groove 14, and the retaining member 30 is stopped against the second groove wall 142 and slides along the surface of the second groove wall 142 under the driving of the rotating member 20. The moving range of the clamping member 30 is determined by the lengths of the rotating member 20 and the second groove wall 142, and the clamping range is conveniently adjusted. For example, the length of the second groove wall 142 and the rotating member 20 exceeds 32mm, the clamping distance between the catch 30 sliding along the second groove wall 142 and the first end wall 11 varies between 0 and 32 mm.

In an embodiment, the second slot wall 142 extends along a radial direction of a maximum circumcircle of the horizontal projection of the sidewall 122 to enlarge an abutting surface of the second slot wall 142 and the retaining member 30, so as to improve the moving stability of the retaining member 30. In one embodiment, the receiving groove 14 extends through the protrusion 123, and the rotating member 20 extends into the receiving groove 14. The receiving groove 14 extends from the first end wall 11 through the protrusion 123 toward the second end wall 121, and the retaining member 30 is movable within the extending range of the receiving groove 14. At least part of the protrusion 123 is located in the hole-shaped space of the mounting hole, the moving range of the retainer 30 is expanded, so that the retainer 30 can be tightly clamped to the ceiling 300.

The retainer 30 is screwed with the rotating member 20, and the first side 33 of the retainer 30 is connected to the first slot wall 141 in a propping manner to be in the folded position, and the second side 34 of the retainer 30 is connected to the second slot wall 142 in a propping manner to be in the unfolded position. In one embodiment, the holder 30 includes a rotating portion 32 connected to the rotating member 20 and a clamping portion 31 extending from the rotating portion 32. The clamping portion 31 includes a first side 33 and a second side 34 opposite to the first side 33, the clamping portion 31 is far away from the second groove wall 142 relative to the rotating portion 32 when in the closed position, and the first side 33 abuts against the first groove wall 141. The clamping portion 31 is far away from the first groove wall 141 relative to the rotating portion 32 in the unfolding position, and the second side 34 abuts against the second groove wall 142.

As shown in fig. 5, 6 and 8, the rotating part 32 is screw-coupled with the rotating member 20, and the clamping part 31 extends from the rotating part 32 to form a cantilever structure. The first side 33 and the second side 34 are oppositely disposed to define a stowed position and a deployed position of the catch 30. In an alternative embodiment, the first side 33 and the second side 34 are parallel to each other. In another alternative embodiment, the second side 34 extends toward the first side 33 in a direction away from the rotating portion 32, such that a portion of the second side 34 is inclined relative to the first side 33, reducing the cross-sectional area of the distal end of the catch 30, reducing resistance to rotation, and maintaining smoothness of rotation. Optionally, the inclined surface of the second side 34 abuts against the second groove wall 142, so that the retainer 30 is inclined relative to the second groove wall 142, the rotation angle and the rotation range of the retainer 30 are increased, the inclination angle of the second groove wall 142 relative to the side wall 122 is reduced, and the structural strength of the side wall 122 is improved.

In an alternative embodiment, the holding member 30 is formed by bending a sheet metal member, and includes an upper bending wall 35, a lower bending wall 37 disposed opposite to the upper bending wall 35, and a connecting wall 36 connecting the upper bending wall 35 and the lower bending wall 37, and the rotating member 20 is respectively in threaded connection with the upper bending wall 35 and the lower bending wall 37, so that the holding member 30 can rotate along with the rotating member 20 and linearly move along the axial direction of the rotating member 20, and the movement stability is good. The connection portions of the upper bending wall 35 and the lower bending wall 37 with the rotating member 20 form the rotating portion 32, and the ends of the upper bending wall 35 and the lower bending wall 37 close to the accommodating groove 14 are formed as circular arc surfaces, so as to improve the flexibility of rotation. The connecting wall 36 constitutes the first side 33 of the retainer 30, and the edge of the upper bent wall 35 and/or the lower bent wall 37 away from the connecting wall 36 constitutes the second side 34 to define the rotational range of the retainer 30. In an alternative embodiment, the upper folded wall 35 extends out of the rotating portion 32 by a length equal to the length of the lower folded wall 37 extending out of the rotating portion 32. In another alternative embodiment, the length of the upper bending wall 35 extending out of the rotating portion 32 is less than the length of the lower bending wall 37 extending out of the rotating portion 32, so as to reduce the weight of the retaining member 30, reduce the deflection generated by the cantilever, improve the flexibility of the rotating connection between the rotating member 20 and the retaining member 30, and keep the clamping size of the retaining member 30 and the first end wall 11 stable.

In one embodiment, the rotating member 20 includes an adjusting portion 22 and a rod portion 21 protruding from the adjusting portion 22 in a cylindrical shape, and the adjusting portion 22 is limited on the first end wall 11. The shaft portion 21 extends through the first end wall 11 toward the second end wall 121. The lever body 21 includes a first screw portion 23, and the retainer 30 is screw-coupled to the first screw portion 23.

The adjusting portion 22 is located at one end of the rod body portion 21 to limit the depth of the inserting fit of the rotating member 20 with the assembling body 10, wherein the surface of the adjusting portion 22 exposed at one side of the assembling body 10 is provided with an adjusting structure such as a straight-line-shaped, cross-shaped, hexagonal-shaped, etc. adjusting groove or hole, etc. for the user to drive the rotating member 20 to rotate by a tool. The other end of the lever body 21 passes through the first end wall 11 and is connected to the fitting body 10 or a fitting mounted to the fitting body 10 to stabilize the mounting position of the rotation member 20 and to rotate smoothly.

The holding member 30 is connected to the rod body 21 and is spirally connected to the first spiral part 23, so that during the rotation of the rotating member 20, the holding member 30 rotates along with the rotation of the first spiral part 23 and moves linearly along the axial direction of the first spiral part 23 after being blocked by the first groove wall 141 or the second groove wall 142.

In an alternative embodiment, the body portion 21 further includes a second spiral part 24 between the first spiral part 23 and the regulating part 22, and the friction force of the second spiral part 24 with the retainer 30 is greater than the friction force of the first spiral part 23 with the retainer 30. The second screw portion 24 and the first screw portion 23 are distributed on the lever body portion 21 for guiding the rotation and sliding of the retainer 30. The frictional force of the screw connection between the second screw portion 24 and the retaining member 30 is greater than the frictional force of the screw connection between the first screw portion 23 and the retaining member 30, so as to avoid the disadvantage that the retaining member 30 cannot be rotationally attached to the first groove wall 141 or the second groove wall 142 in the area of the first screw portion 23, so that the retaining member 30 is tightly attached to the assembly main body 10 at the second screw portion 24 and maintains the expanded position or the collapsed position, and the correction effect is good. The rotation resistance of the holding member 30 at the first screw portion 23 is small, so that the holding member 30 can be moved and adjusted quickly, the driving force required by the rotating member 20 is reduced, and the use is flexible.

In another alternative embodiment, the thread sizes of the second spiral 24 and the first spiral 23 are the same, and the roughness of the second spiral 24 is greater than the roughness of the first spiral 23. In another alternative embodiment, a coating or a film is sprayed on a portion of the surface of the first spiral part 23 to form the second spiral part 24, so that the friction force between the second spiral part 24 and the holding member 30 is greater than the friction force between the first spiral part 23 and the holding member 30. For example, glue dropping resistance is sprayed on the surface of one end of the first spiral part 23 close to the adjusting part 22 to form the second spiral part 24, and the friction force of the second spiral part 24 is adjusted, wherein the glue dropping resistance is resin, has stable chemical performance, is acid and alkali resistant, and does not oxidize and corrode metal. The resistance to the falling of the glue not only increases the frictional force of the second screw portion 24 but also maintains the stability of the surface quality of the rotating member 20. In an alternative embodiment, the second spiral part 24 is provided at a portion of the first spiral part 23, and the other portion of the body part 21 is provided as the first spiral part 23. For example, the distance between the second spiral part 24 and the first end wall 11 is 5mm, and the width of the second spiral part 24 in the axial direction of the rod body part 21 is set to 10-15 mm, so that when the holding member 30 enters the range of the second spiral part 24, the holding member 30 can be rotated to the unfolding position, and the holding position of the holding member 30 and the first end wall 11 for holding the ceiling 300 can be improved and stabilized.
