[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0037] This application discloses a support assembly 10 to replace the mounting bracket in the support device of the prior art. The improved support device is adapted to photographic equipment with a radially protruding conversion lens and its accessories on the lens barrel. It can avoid the conversion lens and its accessories when the photographic equipment switches between horizontal and vertical shooting, meet the shooting needs of various photographic equipment such as horizontal and vertical shooting, and improve the adaptability of the support device to different photographic equipment.

[0038] Please refer to Figures 1 to 6 The bracket assembly 10 includes a flip bracket 100, a mounting bracket 200, a hinge structure 300, and a bolt assembly 400. The flip bracket 100 includes a fixed frame 101 and a flip frame 102. The fixed frame 101 is used to be mounted on the second base 302 of the bracket device. The hinge structure 300 connects the fixed frame 101 and the flip frame 102. The flip frame 102 is rotatably connected to the fixed frame 101 through the hinge structure 300. The mounting bracket 200 includes a first frame 201 and a second frame 202 disposed on the first frame 201. The first frame 201 is connected to the flip frame 102. The first frame 201 can rotate around the rotation axis of the hinge structure 300 with the flip frame 102. The second frame 202 is used to mount shooting auxiliary equipment such as focusing lamps and flashlights. The position of the second frame 202 on the first frame 201 is adjustable.

[0039] The bracket assembly 10 can replace the mounting bracket in existing bracket devices. The bracket assembly 10 is mounted on the second base 302 via a fixing bracket 101. A photographic device with a radially protruding conversion lens and its accessories mounted on the lens barrel is mounted on the first base 301. As the first base 301 rotates relative to the second base 302, the flip-up bracket 102 can flip relative to the fixing bracket 101 away from the lens barrel, i.e., towards... Figure 7 The w-direction rotation shown is used to avoid the protruding conversion lens and its accessories on the lens barrel, so as to meet the switching between horizontal and vertical shooting and other shooting angles of the above-mentioned photographic equipment, and improve the adaptability of the bracket assembly 10 and the bracket device including the bracket assembly 10 to various photographic equipment and shooting needs.

[0040] In some embodiments, please continue to refer to Figures 1 to 5 The flipping frame 102, the fixing frame 101, and the first frame 201 are all elongated plate-like structures. To reduce weight, through holes are provided in the flipping frame 102 to create a hollow structure. The extension direction of the fixing frame 101 is the first direction. One end of the fixing frame 101 in the first direction is rotatably connected to the flipping frame 102, and the other end is used to connect to the second base 302. The flipping frame 102 has a first position during the flipping process relative to the fixing frame 101. Please refer to [reference needed]. Figure 1 and Figure 6 The first position is the position where the entire bracket assembly 10 supports and installs the shooting auxiliary equipment to ensure that the shooting auxiliary equipment works normally. When the flip frame 102 is in the first position, the flip frame 102 and the second seat 302 are arranged on both sides of the fixed frame 101 in the second direction. The extension direction of the flip frame 102 is the same as the extension direction of the fixed frame 101, and the surface of the flip frame 102 is also in contact with the fixed frame 101 so that the fixed frame 101 holds the flip frame 102 and restricts the flip frame 102 from rotating toward the fixed frame 101.

[0041] In one embodiment, when the support assembly 10 needs to cooperate to avoid the protruding conversion lens and its accessories on the lens barrel of the photographic equipment, the user can orient the flip frame 102 relative to the fixed frame 101 in a direction away from the fixed frame 101, such as... Figure 7 The preset angle is flipped in the w direction as shown to reserve space at the positions of the fixing frame 101 and the second base 302 to accommodate the switching between horizontal and vertical shooting by the photographic equipment. Please refer to... Figure 7 The tilting frame 102 also has a second position relative to the fixed frame 101, and the tilting frame 102 can rotate from the first position relative to the fixed frame 101 by a preset angle to the second position. Preferably, the preset angle can be 90° or 180°. Further, a restraining structure is provided between the fixed frame 101 and the tilting frame 102 to restrict the tilting frame 102 from continuing to tilt in a direction away from the fixed frame 101.

[0042] When the preset angle is 90°, in the second position, the flipping frame 102 extends in the second direction, and the flipping frame 102 and the second seat 302 are arranged on both sides of the fixed frame 101 in the second direction.

[0043] When the preset angle is 180°, in the second position, the extension direction of the flipping frame 102 is the same as the extension direction of the fixed frame 101, and the flipping frame 102 and the second seat 302 are arranged on both sides of the fixed frame 101 in the first direction.

[0044] Of course, in other embodiments, the preset angle can be other values, such as greater than or less than 180°.

[0045] In some embodiments, please refer to Figure 2 and Figure 4 The flipping frame 102 flips relative to the fixed frame 101 via a hinge structure 300. The hinge structure 300 includes a flipping seat 103 and a fixed seat 108. The flipping seat 103 is connected to the flipping frame 102 by screws. There are two fixed seats 108, which are spaced apart in the direction of the rotation axis of the flipping frame 102. The fixed seats 108 are installed on the fixed frame 101 by screws. The flipping seat 103 is located between the two fixed seats 108. The flipping seat 103 and the fixed seat 108 are sealed and inserted together. One of the flipping seat 103 and the fixed seat 108 has a recess and the other has a protrusion. The protrusion is located inside the recess. A sealing ring 107 is installed on the protrusion. The flipping seat 103 and the fixed seat 108 can be sealed and engaged by the sealing ring 107.

[0046] The hinge structure 300 also includes a hinge shaft 104, a compression spring 106, and a steel ball 105. The hinge shaft 104 passes through the flip seat 103, and its two ends are respectively inserted into two fixed seats 108. Four ball sockets at 90-degree angles to each other are provided on both axial sides of the flip seat 103. Two of the four ball sockets on each side are arranged radially in a group, and the two groups of ball sockets are arranged perpendicularly. The ball sockets on both sides of the flip seat 103 correspond one-to-one axially. Two mounting holes 1081 are provided on the side of the fixed seat 108 facing the flip seat 103. The positions of the two mounting holes 1081... The position of the spring 106 corresponds to the position of the two ball sockets arranged radially in one set. The spring 106 is located in the mounting hole 1081, and the steel ball 105 is pressed between the spring 106 and the ball socket. The resulting abutment force is used for the precise positioning of the flip seat 103. The number of springs 106 and steel balls 105 corresponds one-to-one with the mounting hole 1081. When the flip seat 103 rotates 90° relative to the fixed seat 108, the steel ball 105 enters the other set of ball sockets of the flip seat 103 and abuts and is positioned. After rotating another 90 degrees, the steel ball 105 returns to one set of ball sockets of the flip seat 103 and abuts and is positioned.

[0047] In other embodiments, the flipping frame 102 can also be flipped relative to the fixed frame 101 via other rotating shaft structures, which is not limited here.

[0048] In some embodiments, please refer to Figures 1 to 7 The flipping frame 102 is connected to the fixed frame 101 at one end in its extension direction and to the first frame 201 at the other end. The extension direction of the flipping frame 102 is perpendicular to the extension direction of the first frame 201. The flipping frame 102 can be integrally formed with the first frame 201, so that the flipping frame 102 and the first frame 201 form an L-shaped structure. Of course, the flipping frame 102 can also be set separately from the first frame 201. The first frame 201 is installed on the flipping frame 102 by screws.

[0049] The second frame 202 is connected to the side of the first frame 201 facing the flipping frame 102. The position of the second frame 202 relative to the first frame 201 in the extending direction of the first frame 201 is adjustable. Alternatively, in other embodiments, the position of the second frame 202 relative to the first frame 201 can also be adjusted in a direction perpendicular to the extending direction of the first frame 201, thereby realizing the adjustment of the position of the second frame 202 relative to the first frame 201.

[0050] In some embodiments, please refer to Figures 1 to 5 The support assembly 10 includes a bolt assembly 400. After the second frame 202 is adjusted relative to the first frame 201, the second frame 202 and the first frame 201 can be fixedly connected by the bolt assembly 400. One of the second frame 202 and the first frame 201 has an elongated hole 2011, the extension direction of which is the same as the extension direction of the first frame 201. The bolt assembly 400 passes through the elongated hole 2011. In one embodiment, the elongated hole 2011 is located on the first frame 201, and the second frame 202 can move relative to the first frame 201 in the extension direction of the elongated hole 2011. After the second frame 202 is moved into place, the bolt assembly 400 is locked, thus achieving a fixed connection between the first frame 201 and the second frame 202. In one embodiment, the elongated hole 2011 is located on the second frame 202, which is clamped on both sides of the first frame 201. In this structure, the displacement of the second frame 202 relative to the first frame 201 is relatively small.

[0051] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The second frame 202 has a mounting part 2021 and two clamping arms 2022. The mounting part 2021 is connected to the two clamping arms 2022. The mounting part 2021 is located on the side of the first frame 201 facing the flipping frame 102. The two clamping arms 2022 are arranged on both sides of the first frame 201 in a direction perpendicular to the extension direction of the first frame 201. The bolt assembly 400 passes through the two clamping arms 2022 and the first frame 201. When the bolt assembly 400 is tightened, the two clamping arms 2022 are clamped on both sides of the first frame 201, realizing the fixed connection between the first frame 201 and the second frame 202, which helps to improve the stability of the fixed connection between the first frame 201 and the second frame 202.

[0052] In an embodiment where the elongated hole is located on the second frame 202, the elongated hole may be located on the clamping arm 2022, and both clamping arms 2022 are provided with elongated holes.

[0053] In one embodiment, the clamping arm 2022 can be omitted from the second frame 202. An elongated hole 2011 is located on the first frame 201, and the depth direction of the elongated hole 2011 is perpendicular to the extension direction of the first frame 201. The first frame 201 also has an elongated slot or through hole, the extension direction and depth direction of which can be referenced. Figure 2 The extension direction and depth direction of the long slot 2012 are the same as the extension direction of the first frame 201. The depth direction of the long slot or through hole is perpendicular to the depth direction of the long hole 2011. A part of the second frame 202 can extend into the long slot or through hole and can move along the long slot or through hole to adjust the position of the second frame 202 relative to the first frame 201. The bolt assembly 400 is located in the long hole 2011. The bolt assembly 400 passes through the part of the second frame 202 that extends into the long slot or through hole. After the bolt assembly 400 is locked, the first frame 201 and the second frame 202 are fixedly connected.

[0054] In some embodiments, please continue to refer to Figure 5 The clamping arm 2022 of the second frame 202 has a connecting end and a cantilever end located at both ends of its extension direction. The clamping arm 2022 is connected to the mounting part 2021 through the connecting end. The cantilever end has a limiting part 2023, which can be a protruding structure located at the cantilever end and facing the first frame 201. This protruding structure can be integrally formed with the clamping arm 2022 or arranged separately. The limiting part 2023 can abut against the first frame 201 in the arrangement direction of the mounting part 2021 and the first frame 201, restricting the first frame 201 from moving away from the mounting part 2021, so that the first frame 201 is restricted between the two clamping arms 2022. In other words, the second frame 202 is used to install shooting aids. The auxiliary device, by providing a limiting part 2023 on the second frame 202 that abuts against the first frame 201, allows the second frame 202 to slide only along the extension direction of the first frame 201. With the cooperation of the bolt assembly 400, the position of the shooting auxiliary device relative to the first frame 201 can be adjusted and locked with the first frame 201, and the shooting auxiliary device is prevented from shaking or swaying after the bolt assembly 400 is locked. In addition, by abutting against the first frame 201 on the second frame 202, the first frame 201 and the second frame 202 can be pre-positioned during the installation of the first frame 201 and the second frame 202, which facilitates the assembly of the bracket assembly 10 and improves the assembly efficiency of the bracket assembly 10.

[0055] In some embodiments, the limiting part 2023 may be a protrusion provided on the cantilever end, and a corresponding recess is provided on the first frame 201; or the limiting part 2023 may be a recess on the cantilever end, and a corresponding protrusion is provided on the first frame 201; the protrusion is located inside the recess, and the sidewalls of the protrusion and the recess abut against each other in the arrangement direction of the first frame 201 and the mounting part 2021, so that the first frame 201 is restricted between the two clamping arms 2022.

[0056] In some embodiments, for the bolt assembly 400, please refer to... Figure 1 , Figure 2 and Figure 5 The bolt assembly 400 includes a screw 205, a nut seat 203, and a wrench 206. The extension direction of the screw 205 is perpendicular to the extension direction of the first frame 201. The screw 205 has a screwing end and a mating end located at both ends of its extension direction. The mating end of the screw 205 is threadedly connected to the nut seat 203. The wrench 206 is sleeved on the screwing end of the screw 205 and has an anti-rotation engagement with the screw 205. The anti-rotation engagement means that the wrench 206 abuts against the screwing end of the screw 205 in the rotation direction of the wrench 206 or in the circumferential direction of the screw 205, and the screw 205 can be rotated by the wrench 206.

[0057] Specifically, the head of the screw 205 engages with the wrench 206, forming the screw-tightening end of the screw 205. The outer circumferential surface of the screw 205 head includes a prism surface, which can be a quadrangular prism, a triangular prism, or a hexagonal prism. Correspondingly, the inner circumferential surface of the wrench 206 has a prism surface adapted to the head of the screw 205. The wrench 206 is fitted onto the head of the screw 205, and the prism surface of the wrench 206 fits against the prism surface of the head of the screw 205, enabling a non-rotational engagement between the wrench 206 and the head of the screw 205. The user can rotate the screw 205 by turning the wrench 206 to lock or loosen the bolt assembly 400. After the bolt assembly 400 is loosened, the second frame 202 can move and adjust relative to the first frame 201. After the bolt assembly 400 is locked, the second frame 202 can be fixed relative to the first frame 201.

[0058] In one embodiment, the wrench 206 has a sleeve 2061 with an outward protrusion 2063 on its outer circumferential surface. The user can apply torque to the outward protrusion 2063 to rotate the wrench 206 and the screw 205. In the above embodiment, the wrench 206 is designed to allow for adjustment of the position of the second frame 202 without the need for auxiliary tools. The outward protrusion 2063 on the wrench 206 helps reduce the torque required for the user to rotate the wrench 206.

[0059] In some embodiments, please refer to Figure 2 and Figure 5 The bolt assembly 400 includes a screw 207 and an elastic element 208. The screw 207 is mounted on the head of the screw 205, and the axis of the screw 207 is coaxial with the axis of the screw 205. The elastic element 208 is clamped between the wrench 206 and the head of the screw 207. Under the elastic action of the elastic element 208, the wrench 206 can move axially relative to the screw 205.

[0060] Specifically, the sleeve 2061 of the wrench 206 has a radially inwardly protruding portion 2062 facing the screw 205 at one end in the axial direction of the screw 205. The prism surface that fits against the head of the screw 205 is located on the inner circumferential surface of the radially inwardly protruding portion 2062. The elastic element 208 is a helical spring, which is fitted onto the head of the screw 205 and located inside the sleeve 2061 of the wrench 206. One end of the elastic element 208 in its extending direction contacts or elastically abuts against the head of the screw 207, and the other end contacts or elastically abuts against the radially inwardly protruding portion 2062 of the wrench 206. The user can adjust the screw 205 axially... The upper compression elastic element 208 is used to pull the screw wrench 206 outward, so that the prism face of the screw wrench 206 is separated from the prism face of the bolt head. While keeping the two prism faces separated, the screw wrench 206 can be rotated to change the orientation of the outward protrusion 2063 on the screw wrench 206. This allows the user to rotate the screw wrench 206 by applying force to the outward protrusion 2063 in a small space. Then, the pulling force on the screw wrench 206 is released. Under the elastic action of the elastic element 208, the screw wrench 206 moves toward the screw 205 and makes the prism face of the screw wrench 206 fit against the prism face of the screw head 205.

The elongated groove 2012 has a first groove sidewall 2013 and a second groove sidewall 2014 arranged opposite to each other in the arrangement direction of the two clamping arms 2022. A nut seat 203 passes through one of the clamping arms 2022 and the first groove sidewall 2013. A limited... A first stop structure is provided to prevent the screw 205 from disengaging from the clamping arm 2022 and the first groove sidewall 2013. The screw 205 passes through the other clamping arm 2022 and the second groove sidewall 2014. A second stop structure is provided on the screw 205 to restrict its disengagement from the other clamping arm 2022 and the second groove sidewall 2014. The provision of the first stop structure and the second stop structure can achieve the pre-positioning of the screw 205 and the nut seat 203 during the assembly of the bolt assembly 400, which helps to improve the assembly efficiency of the bracket assembly 10.

[0063] In one embodiment, the nut seat 203 may be fixed to one of the clamping arms 2022. During the assembly of the bolt assembly 400, only the pre-positioning of the screw 205 needs to be considered.

[0064] In some embodiments, please continue to refer to Figure 2 and Figure 5 The first stop structure includes a first retaining ring 2031 installed at one end of the nut seat 203. The first retaining ring 2031 is located within the elongated groove 2012. The first retaining ring 2031 can be a C-shaped retaining ring. A baffle is provided at the other end of the nut seat 203. The baffle can be integrally formed with the nut seat 203. The baffle can ensure that the nut seat 203 is installed in place in the side wall 2013 of the first groove, and the first retaining ring 2031 can restrict the nut seat 203 from disengaging from the side wall 2013 of the first groove and the clamping arm 2022. Of course, in other embodiments, the first stop structure can be omitted to reduce the number of parts in the bracket assembly 10.

[0065] In some embodiments, please continue to refer to Figure 2 and Figure 5The second stop structure includes a second retaining ring 2051 mounted on the screw 205. The second retaining ring 2051 is located within the elongated groove 2012. The second retaining ring 2051 can be a C-shaped retaining ring. The head of the screw 205 has a retaining ring with a diameter larger than that of the screw 205. The retaining ring is integrally formed with the screw 205 and is located at the end of the screw 205 head facing the nut seat 203. The screw 205 passes through the clamping arm 2022 and the side wall 2014 of the second groove. A washer 204 is located between the retaining ring and the clamping arm 2022. During the assembly of the screw 205, the retaining ring ensures that the screw 205 is properly installed in the side wall 2014 of the second groove, and the second retaining ring 2051 prevents the screw 205 from dislodging from the side wall 2014 of the second groove and the clamping arm 2022. Of course, in other embodiments, the second stop structure can be omitted to reduce the number of parts in the bracket assembly 10.

[0066] This application also discloses a support device, as shown in the embodiments. Figure 6 and Figure 7 It includes a first base 301, a second base 302, and a bracket assembly 10 in any of the above embodiments. The structure and connection relationship of the first base 301 and the second base 302 are the same as those of the first base 301 and the second base 302 in a bracket device disclosed in Chinese invention patent application document CN120332610A (hereinafter referred to as the prior application). The first base 301 is used to install the photographic equipment, and the second base 302 is connected to the first base 301. The first base 301 can rotate 90° relative to the second base 302 to allow the photographic equipment to switch between horizontal and vertical shooting, or the angle of rotation of the first base 301 relative to the second base 302 is less than 90° or greater than 90° to enable the photographic equipment to have other shooting angles and postures. The fixing frame 101 is installed on the second base 302. Unlike the bracket device in the prior application, the bracket assembly 10 in this application is used to replace the mounting bracket in the bracket device in the prior application, and the rest of the structure is the same as the bracket device in the prior application.

[0067] Please refer to Figure 6 and Figure 7 The fixed frame 101 in the bracket assembly 10 is installed on the second base 302 by screws. When switching between horizontal and vertical shooting of the camera equipment, the flip frame 102 can be rotated to a second position relative to the fixed frame 101 to avoid the protruding structure on the lens barrel of the camera equipment. This allows the bracket device to adapt to the horizontal and vertical shooting switching needs of various camera equipment. Furthermore, shooting auxiliary equipment such as focusing lamps and flashlights can be installed on the second frame 202 in the bracket assembly 10. By moving the second frame 202 relative to the first frame 201, the position of the shooting auxiliary equipment can be adjusted to meet various shooting needs.
