Description

Technical Field

[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to an angle-adjustable hot shoe module and a hot shoe photography component. Background Technology

[0002] With the popularization of photography technology, more and more users are starting to use external flashes to improve the shooting effect of their cameras. As the most common type of external flash, the camera's on-camera flash is widely used in both everyday shooting and professional photography scenarios due to its ease of installation and intuitive control.

[0003] On-camera flashes are typically fixed to the camera via a hot shoe mount on the bottom, allowing for electrical connection and flash synchronization control. Because the on-camera flash is usually fixed relative to the camera, it cannot rotate relative to the camera to adjust the flash angle, thus failing to meet users' needs for multi-angle adjustments.

Detailed Implementation

[0040] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1-4 As shown, an embodiment of the present invention, an adjustable hot shoe module, includes a first hot shoe module 10, a second hot shoe module 20, and a flexible flat cable 30. The first hot shoe module 10 is used to snap onto and electrically connect to the camera hot shoe, while the second hot shoe module 20 is used to mount photographic accessories and electrically connect to them. The flexible flat cable 30 connects the first hot shoe module 10 and the second hot shoe module 20, serving both electrical conductivity and signal transmission functions.

[0042] The second hot shoe module 20 is rotatably connected to the first hot shoe module 10, allowing the second hot shoe module 20 to be flipped relative to the first hot shoe module 10 to adjust its angle. This adjustment, in turn, adjusts the angle of photographic accessories mounted on the second hot shoe module 20 to meet the user's needs for adjusting the angle of the photographic accessories. Photographic accessories include, but are not limited to, flash units, microphones, and viewfinders.

[0043] Specifically, the first hot shoe module 10 is provided with a movable groove 100, and the second hot shoe module 20 is fitted into the movable groove 100 and rotatably connected to the first hot shoe module 10, so that the second hot shoe module 20 can be flipped relative to the first hot shoe module 10 along the movable groove 100. A flexible flat cable 30 is threaded between the first hot shoe module 10 and the second hot shoe module 20, electrically connecting the first hot shoe module 10 and the second hot shoe module 20. Because the flexible flat cable 30 is flexible and can be bent without affecting its conductive connection performance, when the second hot shoe module 20 is flipped relative to the first hot shoe module 10, the flexible flat cable 30 can bend accordingly with the flipping angle of the second hot shoe module 20, always maintaining its connection with the first hot shoe module 10 and the second hot shoe module 20. Figure 3 and Figure 4 As shown.

[0044] Alternatively, to improve the aesthetics and overall appearance of the angle-adjustable hot shoe module, the second hot shoe module 20 can be configured according to the shape of the movable slot 100 so that after the second hot shoe module 20 fits into the movable slot 100, the outer surface of the second hot shoe module 20 can be flush with the opening end face of the movable slot 100.

[0045] Corresponding to the rotatable connection between the second hot shoe module 20 and the first hot shoe module 10, the angle-adjustable hot shoe module may also include a rotating component, through which the second hot shoe module 20 is rotatably connected to the first hot shoe module 10.

[0046] In one embodiment, the rotating component may include a rotating shaft 40 that passes through the second hot shoe module 20 and is connected between two opposing inner wall surfaces of the movable groove 100, the second hot shoe module 20 being able to rotate within the movable groove 100 about the rotating shaft 40.

[0047] To ensure that the second hot shoe module 20 can be positioned at any angle after rotating at any angle within the movable slot 100, the rotating shaft 40 can be a damped rotating shaft. Alternatively, the second hot shoe module 20 can be positioned through the cooperation of the positioning slot 511 and the positioning clip 52. Figure 5 In the illustrated embodiment, the bottom surface of the movable slot 100 is provided with several sets of positioning slot groups 51, which are arranged at intervals along the rotation direction of the second hot shoe module 20 on the bottom surface of the movable slot 100. Each set of positioning slot groups 51 includes at least one positioning slot 511. The second hot shoe module 20 is provided with a retractable positioning member 52 facing the bottom of the movable slot 100. The positioning member 52 can be disengaged and locked into any positioning slot 511 to position the second hot shoe module 20 at the current angle.

[0048] The bottom of the second hot shoe module 20 has a groove 50 for accommodating a positioning clip 52. The retractability of the positioning clip 52 is provided by an elastic member 53, which abuts against the inner bottom surface of the groove 50. The elastic member 53 provides a restoring force to drive the positioning clip 52 to move outward from the groove 50, so as to extend beyond the bottom of the second hot shoe module 20. The elastic member 53 may be, but is not limited to, a spring.

[0049] When the second hot shoe module 20 is rotated, the positioning clip 52 is pressed against the bottom surface of the movable groove 100, compressing the elastic element 53 and retracting inward toward the groove 50. When the positioning clip 52 rotates with the second hot shoe module 20 to the position of the positioning slot 511, it moves outward toward the groove 50 under the restoring force of the elastic element 53 and engages in the positioning slot 511. When the second hot shoe module 20 continues to rotate, the positioning clip 52 can slide out of the positioning slot 511 along the inner surface of the positioning slot 511, and can slide into the positioning slot 511 again after reaching the next positioning slot 511.

[0050] refer to Figure 2 and Figure 6 In one alternative embodiment, each group of positioning slots 51 includes two symmetrically arranged positioning slots 511, and the symmetrical arrangement can be further selected with the midline of the movable groove 100 as the axis of symmetry. All the positioning slots 511 of the several groups of positioning slots 51 form two symmetrical rows of positioning slots on the bottom surface of the movable groove 100, and each positioning slot in the two rows of positioning slots corresponds one-to-one; each row of positioning slots is arranged along the rotation direction of the second hot shoe module 20. Corresponding to the two rows of positioning slots on the bottom surface of the movable groove 100, two positioning clips 52 can be provided, which can simultaneously engage with the two positioning slots 511 of a group of positioning slots 51 or slide out of the two positioning slots 511 of a group of positioning slots 51. Alternatively, the end of the positioning clip 52 is provided with two engaging ends for cooperating with the two positioning slots 511 of a group of positioning slots 51, simultaneously engaging with the two positioning slots 511 of a group of positioning slots 51 or sliding out of the two positioning slots 511 of a group of positioning slots 51. The above two rows of positioning slots ensure that the second hot shoe module 20 can be positioned smoothly at the current angle after rotating to any angle within the movable slot 100, through the positioning card 52 cooperating with the two positioning slots 511 at the same angle, thus avoiding left and right swaying.

[0051] To facilitate the positioning card 52 to enter and exit the positioning card slot 511 along the inner surface of the positioning card slot 511, the inner bottom surface of the positioning card slot 511 and the end face of the positioning card 52 are set as matching arc surfaces, which can be further rounded surfaces.

[0052] Specifically, the positioning slot 511 can be a circular slot, and the end face of the positioning piece 52 can be an arc surface. Alternatively, the positioning slot 511 can be a square slot with an arc-shaped inner bottom surface, and the end of the positioning piece 52 can be a square end with an arc-shaped end face.

[0053] In another embodiment of the rotating assembly, the rotating assembly may also include a snap-fit ​​assembly with a concave-convex fit. A snap-fit ​​assembly is provided between each of the opposite sides of the second hot shoe module 20 and the inner wall surface of the corresponding movable groove 100. The snap-fit ​​assembly includes a matching circular hole and a cylinder, so that the second hot shoe module 20 is snapped into the movable groove 100 by the snap-fit ​​assembly, and can also be rotated within the movable groove 100.

[0054] The rotation of the second hot shoe module 20 within the movable slot 100 is a circular rotation, meaning the rotation trajectory of the second hot shoe module 20 is an arc. Preferably, the bottom surface of the movable slot 100 is set as an arc surface, and the bottom surface of the second hot shoe module 20 facing the movable slot 100 is also an arc surface, so that the second hot shoe module 20 can rotate smoothly within the movable slot 100.

[0055] like Figures 2-4 As shown, in one embodiment, the bottom surface of the movable slot 100 includes a first arcuate surface 110, and the bottom surface of the second hot shoe module 20 facing the movable slot 100 includes a second arcuate surface 210 that matches the first arcuate surface 110. The second arcuate surface 210 of the second hot shoe module 20 fits onto the first arcuate surface 110 of the movable slot 100, so that the second arcuate surface 210 can slide back and forth along the first arcuate surface 110, thereby enabling the second hot shoe module 20 to rotate back and forth within the movable slot 100. Through the matching of the arcuate surfaces, the rotation angle of the second hot shoe module 20 within the movable slot 100 can be 0° to 180°; depending on the length and connection configuration of the flexible flat cable 30, the rotation angle of the second hot shoe module 20 relative to the first hot shoe module 10 can also be 0° to 360°, and the rotation angle range can be determined according to requirements.

[0056] Furthermore, in Figures 2-4 In the illustrated embodiment, the bottom surface of the movable groove 100 further includes a stepped surface 120 connected to the first side of the first arcuate surface 110. The bottom surface of the second hot shoe module 20 further includes a mating surface 220, which is connected to one side of the second arcuate surface 210 corresponding to the stepped surface 120. When the second hot shoe module 20 is in its initial state within the movable groove 100, the second arcuate surface 210 mates with the first arcuate surface 110, and the mating surface 220 mates with the stepped surface 120. When the mating surface 220 mates with the stepped surface 120, it restricts the rotation of the second hot shoe module 20 towards the second side of the first arcuate surface 110. Therefore, rotating the second hot shoe module 20 actually rotates it towards the stepped surface 120. Figures 2-4Taking the placement direction of the adjustable hot shoe module as an example, the stepped surface 120 is located to the right of the first arc-shaped surface 110. In this placement position and initial state, the second hot shoe module 20 can only rotate counterclockwise relative to the first hot shoe module 10. Figure 1 , Figure 2 The initial state shown to Figure 3 , Figure 4 The state after rotation is shown. During reset, the second hot shoe module 20 is rotated clockwise relative to the first hot shoe module 10 until the mating surface 220 abuts against the step surface 120, thus restricting the second hot shoe module 20 from continuing to rotate.

[0057] refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The first hot shoe module 10 may specifically include a first hot shoe base 11, a first hot shoe body 12, and a first circuit board 13. The first hot shoe base 11 serves as a support for the first hot shoe module 10, accommodating the first hot shoe body 12 and the first circuit board 13, and providing structural support. The top of the first hot shoe base 11 is open, thus forming a movable groove 100 on the first hot shoe base 11. The first hot shoe body 12 is disposed at the bottom of the first hot shoe base 11 and is fixed relative to the first hot shoe base 11; the first hot shoe body 12 is used for electrical connection with the camera hot shoe. The first circuit board 13 is disposed inside the first hot shoe base 11, fixed relative to the first hot shoe base 11, and is electrically connected to the first hot shoe body 12 and the flexible flat cable 30, respectively.

[0058] The first hot shoe 11 can be integrally installed or separately installed. For a separate installation, the first hot shoe 11 may include a hollow outer shell 111 and a bottom spacer 112. The bottom spacer 112 fits into the outer shell 111, and its outer periphery is tightly fitted to the inner periphery of the outer shell 111. A movable groove 100 is formed between the outer shell 111 and the bottom spacer 112, such that the surface of the bottom spacer 112 forms the bottom surface of the movable groove 100.

[0059] In an embodiment where the second hot shoe module 20 is rotatably connected to the movable slot 100 via a rotating shaft 40, the opposite ends of the rotating shaft 40 can be inserted into the opposite inner walls of the outer shell 111 of the first hot shoe seat 11, or into the bottom spacer 112. For insertion into the bottom spacer 112, connecting arms 113 can be provided on opposite sides of the bottom spacer 112, each connecting arm 113 having a connecting hole for the end of the rotating shaft 40 to pass through.

[0060] The first hot shoe body 12 may further include a first base 121, a first conductive portion disposed on the first base 121, and a first circuit board 13 disposed on the first base 121. The first conductive portion includes a first central contact, and the first central contact further includes a contact pin 122 and a contact pin spring 123 connected to the contact pin 122. The contact pin 122 is located at the center of the first base 121, is vertically arranged, and extends out of the bottom surface of the first base 121 to form a first central signal terminal for electrical connection with the central contact of the camera hot shoe. The top of the contact pin spring 123, away from the contact pin 122, is inserted into the first circuit board 13 and electrically connected to the first circuit board 13.

[0061] The first conductive part may further include a first accessory contact (not shown), which is located at least one side of the first central contact. One end of the first accessory contact is fixedly connected to the first circuit board 13 and electrically connected to the first circuit board 13. The other end of the first accessory contact is exposed at the bottom of the first base 121 for electrical connection with a corresponding conductive contact on the camera hot shoe.

[0062] The first hot shoe module 10 is used to snap onto the camera hot shoe. In order to keep the first hot shoe module 10 stable on the camera, thereby improving the stability of the entire hot shoe module on the camera hot shoe, the first hot shoe module 10 also includes a locking mechanism. The locking mechanism locks the first hot shoe module 10 onto the camera hot shoe by cooperating with the locking hole on the camera hot shoe.

[0063] Alternatively, the locking mechanism includes a retractable locking component 14 disposed within the first hot shoe mount 11. The locking component 14 can extend out from the bottom of the first hot shoe mount 11 to insert into the locking hole of the camera hot shoe, or retract into the first hot shoe mount 11 to disengage from the locking hole. When the locking component 14 is inserted into the locking hole of the camera hot shoe, it locks the first hot shoe module 10 onto the camera hot shoe; when the locking component 14 disengages from the locking hole and retracts into the first hot shoe mount, it releases the first hot shoe module 10 from the camera hot shoe, allowing the first hot shoe module 10 to be removed from the camera hot shoe.

[0064] The locking assembly 14 may further include a locking post 141 and a first elastic member 142. The locking post 141 is vertically disposed within the first hot shoe 11, and the first elastic member 142 abuts against the locking post 141 and the inner wall of the first hot shoe 11. In its natural state, the end of the locking post 141 away from the first elastic member 142 extends out of the bottom of the first hot shoe 11. When the first hot shoe module 10 is locked onto the camera hot shoe, the first elastic member 142 is in its natural state; when pressure is applied to the locking post 141 to retract it to the bottom of the first hot shoe 11, the first elastic member 142 is simultaneously compressed.

[0065] The locking post 141 can be a cylindrical structure, a polyhedral structure, or an irregular structure; its shape is not limited. The first elastic element 142 can be a spring or a spring sheet.

[0066] The locking mechanism also includes an unlocking component 15 for unlocking the locking component 14. The unlocking component 15 is used to apply pressure to the locking component 14, causing it to disengage from the locking hole on the camera hot shoe and retract into the bottom of the first hot shoe mount 11. The unlocking component 15 is disposed on the first hot shoe mount 11 and can move back and forth in the direction of entering and exiting the first hot shoe mount 11; the direction of movement of the unlocking component 15 is perpendicular to the extension and retraction direction of the locking component 14.

[0067] The unlocking component 15 and the locking component 14 are provided with matching guide portions. When the unlocking component 15 is pressed to move it toward the first hot shoe 11, the guide portion 150 of the unlocking component 15 and the guide portion 140 of the locking component 14 slide toward each other, driving the locking component 14 to move upward and retract into the first hot shoe 11. The guide portions 140 and 150 may be guide ramps or guide arc surfaces.

[0068] When the unlocking component 15 is in its natural state, the guide portion 150 of the unlocking component 15 does not contact the guide portion 140 of the locking component 14, or only partially abuts against it. When the unlocking component 15 is subjected to force and moves in the direction of entering the first hot shoe seat 11, the guide portion 150 of the unlocking component 15 slides along the guide portion 140 of the locking component 14 and lifts the locking component 14.

[0069] The guide portion 140 of the locking component 14 is disposed on the locking post 141, and the guide portion 150 of the unlocking component 15 is disposed on the unlocking member 151.

[0070] The unlocking component 15 may specifically include an unlocking member 151 and a second elastic member 152. The unlocking member 151 is movably fitted on the side wall of the first hot shoe seat 11, and a portion of it may protrude from the outer surface of the first hot shoe seat 11 to form a pressing portion that can be pressed by the user. The second elastic member 152 is disposed inside the first hot shoe seat 11, abutting between the unlocking member 151 and the inner wall surface of the first hot shoe seat 11, and is used to provide a restoring force to drive the unlocking member 151 to reset after being subjected to force. In its natural state, the second elastic member 152 allows the unlocking member 151 to protrude from the outer surface of the first hot shoe seat 11, and the guide portion 150 on the unlocking member 151 is away from or partially engages with the guide portion 140 of the locking post 141, so that the guide portion 150 on the unlocking member 151 and the guide portion 140 of the locking post 141 have a relative sliding stroke. Pressing the unlocking member 151 against the outer surface of the first hot shoe 11 compresses the second elastic member 152, causing the unlocking member 151 to move toward the inside of the first hot shoe 11. The guide portion 150 of the unlocking assembly 15 slides along the guide portion 140 of the locking post 141, thereby lifting the locking post 141.

[0071] The second elastic element 152 can be a spring or a spring sheet.

[0072] See again Figure 1 , Figure 2 and Figure 6 The second hot shoe module 20 may specifically include a second hot shoe base 21, a second hot shoe body 22, and a second circuit board 23. The second hot shoe base 21 serves as a support for the second hot shoe module 20, accommodating the second hot shoe body 22 and the second circuit board 23, and providing structural support. The second hot shoe module 20 is fitted into the movable slot 100 via the second hot shoe base 21 and is rotatably connected to the first hot shoe base 11 of the first hot shoe module 10. The second hot shoe body 22 is located on the top of the second hot shoe base 21 (i.e., the side facing away from the first hot shoe module 10) and is used for attaching and electrically connecting photographic accessories. The second circuit board 23 is located within the second hot shoe base 21 and is electrically connected to the flexible flat cable 30 and the second hot shoe body 22. The second circuit board 23 is fixed relative to the second hot shoe seat 21 within the second hot shoe seat 21. When the second hot shoe module 20 is flipped relative to the first hot shoe module 10 within the movable slot 100, the first hot shoe seat 11 is actually flipped relative to the first hot shoe module 10, and the second hot shoe body 22 and the second circuit board 23 flip along with the first hot shoe seat 11.

[0073] The second hot shoe mount 21 can be integrally installed or separately installed. For a separate installation, the second hot shoe mount 21 may include a bottom shell 211 and a top shell 212 that is fitted onto the bottom shell 211. The top shell 212 has a locking slot 213 for mounting the second hot shoe body 22. The bottom surface of the bottom shell 211 forms the bottom surface of the second hot shoe mount 21, which is fitted to the bottom surface of the movable groove 100.

[0074] In an embodiment where the second hot shoe module 20 is rotatably connected to the movable slot 100 via a rotating shaft 40, the rotating shaft 40 passes through the front shell 212 and connects to the two opposing inner walls of the movable slot 100, thereby rotatably connecting the second hot shoe seat 21 to the movable slot 100. A positioning clip 52 for positioning the second hot shoe module 20 within the movable slot 100 can be inserted into the bottom shell 211 and can extend and retract relative to the bottom shell 211 to engage with or disengage from the positioning clip 511 of the movable slot 100.

[0075] The second hot shoe body 22 may further include a second base 221 and a second conductive part disposed on the second base 221.

[0076] like Figure 1 and Figure 6In the illustrated embodiment, the second conductive portion may include a second central contact, which includes a metal post 222. The metal post 222 is inserted into the central hole of the second base 221, forming a second central signal terminal for electrical connection with the central contact of the photographic accessory. The second conductive portion also includes a metal sheet 223 with a snap-fit ​​interface. The metal sheet 223 is fixed to the second base 221, with an opening at its center exposing the metal post 222. The snap-fit ​​interface of the metal sheet 223 is used for sliding snap-fit ​​with the photographic accessory and forms a side signal terminal for electrical connection with the side contact of the photographic accessory. The second conductive portion also includes a metal spring 224 with a spring arm. The metal spring 224 is disposed on the metal sheet 223, and the spring arm provides elastic force to secure the photographic accessory within the second conductive portion.

[0077] The second conductive part also includes a second accessory contact. One end of the second central contact is connected to the second circuit board 23, and the other end protrudes from the top of the second base 221 for electrical connection with the corresponding conductive contact of the photographic accessory. Further, in Figure 1 and Figure 6 In the illustrated embodiment, the second accessory contact is a contact array 225 located on at least one side of the second central contact. The contact array 225 can be formed by arranging a plurality of pin arrays. Each pin is embedded within the second base 221, with one end extending towards and connecting to the second circuit board 23, and the other end extending towards and exposed on the top of the second base 221. Depending on the embedding of the pin within the second base 221 and the connection requirements at both ends, the shape of the pin can be, but is not limited to, Z-shaped, L-shaped, etc.

[0078] Corresponding to the second accessory contact, the first accessory contact of the first hot shoe body 12 is a contact array (not shown) located on at least one side of the first central contact. This contact array can be formed by arranging several pin arrays. The pins are embedded in the first base 121, with one end extending towards and connecting to the first circuit board 13, and the other end extending towards and exposed at the bottom of the first base 121. The shape of the pins can be, but is not limited to, Z-shaped, L-shaped, etc.

[0079] The number of contact pins in the first accessory contact and the second accessory contact is the same, and they correspond one-to-one.

[0080] Combination Figure 3 and Figure 6One end of the flexible flat cable 30 is connected to the first circuit board 13, and the other end is connected to the second circuit board 23. The flexible flat cable 30 can be disposed between the inner wall of the movable groove 100 and the outer surface of the second hot shoe 21, with one end passing through the bottom surface of the movable groove 100 and connecting to the first circuit board 13, and the other end passing into the second hot shoe 21 to connect to the second circuit board 23. Alternatively, the flexible flat cable 30 can pass through the side of the second hot shoe 21, with one end connected to the second circuit board 23, and the other end passing through the bottom surface of the movable groove 100 and connecting to the first circuit board 13.

[0081] One end of the flexible flat cable 30 can be directly connected to the first circuit board 13, or connected to the first circuit board 13 via a connector; the other end of the flexible flat cable 30 can be directly connected to the second circuit board 23, or connected to the second circuit board 23 via a connector. Compared to direct connection to the circuit board, the flexible flat cable 30 connects to the first circuit board 13 and / or the second circuit board 23 via a connector, which facilitates connection and disconnection, and also facilitates the replacement of the flexible flat cable 30 or the circuit board.

[0082] Alternatively, the flexible flat cable 30 can be a flexible printed circuit board or a combination of multiple parallel conductors wrapped with a flexible insulating material.

[0083] The flexible flat cable 30 can have a single conductive path or multiple conductive paths, depending on the required functions of the hot shoe module. For example, when the photographic accessory is a flash, the flexible flat cable 30, through a multi-path conductive circuit, not only has a flash triggering function but also supports TTL mode.

[0084] like Figures 7-8 As shown, another embodiment of the present invention, an angle-adjustable hot shoe module, includes a first hot shoe module 10, a second hot shoe module 20, and a flexible flat cable 30. The first hot shoe module 10 is used to snap onto and electrically connect to the camera hot shoe, and the second hot shoe module 20 is used to snap onto and electrically connect to photographic accessories. The flexible flat cable 30 connects the first hot shoe module 10 and the second hot shoe module 20, serving to conduct electricity and transmit signals.

[0085] The first hot shoe module 10 has a movable slot 100, and the second hot shoe module 20 is disposed within the movable slot 100 and rotatably connected to the first hot shoe module 10. This allows the second hot shoe module 20 to be flipped relative to the first hot shoe module 10, adjusting its angle and thus the angle of the photographic accessories attached to it, to meet the user's needs for adjusting the angle of the photographic accessories. Photographic accessories include, but are not limited to, flash units, microphones, etc.

[0086] The specific structure and fit of the first hot shoe module 10 and the second hot shoe module 20, the connection method of the flexible flat cable 30, and other structural components can all refer to the above. Figures 1-6The embodiments shown are not described in detail here.

[0087] Should Figures 7-8 The illustrated embodiment is the same as the one described above. Figures 1-6 The difference in the embodiment shown is that in the second hot shoe module 20, the second accessory contact includes a plurality of connection contacts 226 arranged around the second central contact (i.e., metal post 222). Each connection contact 226 is formed by a conductive post that is vertically inserted into the second base 221. One end of the conductive post is electrically connected to the second circuit board, and the other end is exposed at the bottom of the second base 221 for electrical connection with the corresponding conductive contact of the photographic accessory.

[0088] Similarly, in the first hot shoe module 10, the first accessory contact includes several connecting contacts (not shown) arranged around the first central contact. Each connecting contact is formed by a conductive post vertically inserted into the first base 121. One end of the conductive post is electrically connected to the first circuit board, and the other end protrudes from the bottom of the first base 121 for electrical connection with the corresponding conductive contact on the camera hot shoe. The first accessory contact is arranged in correspondence with the second accessory contact.

[0089] above Figures 7-8 The illustrated embodiments and Figures 1-6 The embodiments shown form different hot shoe structures.

[0090] Understandably, the arrangement of the second accessory contact in the second hot shoe module 20 and the first accessory contact in the first hot shoe module 10 in this invention enables the angle-adjustable hot shoe module to support the installation of various photographic accessories on the camera, meeting diverse user needs and not limited to a single function or usage. The structural composition of the second hot shoe body 22 of the second hot shoe module 20 and the first hot shoe body 12 of the first hot shoe module 10 is not limited to... Figure 1 and Figure 7 The embodiments shown can also employ other structural forms based on existing technologies.

[0091] In use, the adjustable hot shoe module of this invention is electrically connected to the camera hot shoe via a first hot shoe module 10. A photographic accessory is then electrically connected to the second hot shoe module 20, thus mounting the accessory onto the camera hot shoe and establishing an electrical connection. When the photographic accessory needs to be adjusted during operation, simply rotate the second hot shoe module 20 relative to the first hot shoe module 10 until the desired angle is reached and the module is positioned.

[0092] refer to Figure 9 The hot shoe photography assembly of this utility model includes an angle-adjustable hot shoe module and a photography accessory 60 as described in any of the above embodiments; the photography accessory 60 is disposed on the second hot shoe module 20 of the angle-adjustable hot shoe module and is electrically connected to the second hot shoe module 20.

[0093] In one embodiment, the photographic accessory 60 can be fixed to the second hot shoe module 20 by snap-fit, forming an integral part of the second hot shoe module 20 and being detachable, thereby achieving angle adjustment of the photographic accessory 60 by flipping the second hot shoe module 20 relative to the first hot shoe module 10.

[0094] In another embodiment, the photography accessory 60 can be integrated with the second hot shoe module 20, so that the photography accessory 60 and the angle-adjustable hot shoe module form an integrated hot shoe photography assembly, without the need to disassemble or assemble the photography accessory 60.

[0095] In the embodiment where the photographic accessory 60 is a flash unit, the second central contact (i.e., metal post 222) on the second hot shoe module 20 serves as a flash triggering control contact, electrically connected to the X contact of the flash unit, thereby enabling the flash triggering function. Combined with the setting of the second accessory contact in the second hot shoe module 20, which is used to electrically connect to the corresponding conductive contact of the flash unit, other functions besides flash triggering can be implemented, such as mode settings (e.g., TTL mode) and parameter settings.

[0096] When the photographic accessory 60 is a microphone or viewfinder or other accessory, it is electrically connected to the corresponding contact of the second conductive part on the second hot shoe module 20 according to the hot shoe structure of the specific accessory, so as to realize the conductive use of the photographic accessory 60.

[0097] Because the photographic accessory is mounted on the camera's hot shoe via the second hot shoe module 20 and the first hot shoe module 10, its mounting height on the camera is increased. This allows for smooth angle adjustment of the photographic accessory relative to the camera without interference with surrounding camera components. Furthermore, the connection between the first hot shoe module 10 and the second hot shoe module 20 via the flexible flat cable 30 ensures a stable electrical connection between the second hot shoe module 20 and the first hot shoe module 10 throughout the rotation process, guaranteeing stable signal transmission.

[0098] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
