[0036] Existing photographic and video equipment has a support groove at its hot shoe interface, within which a support part is located. When the hot shoe assembly is connected to the hot shoe interface of the photographic and video equipment, the connecting part on the hot shoe assembly extends into and is supported within the support groove. The existing connecting part has a connecting portion designed to fit snugly against the support part. However, due to the significant friction between the connecting portion and the support part, considerable wear and tear occurs during the installation and removal of the hot shoe assembly.

[0037] One embodiment of the present invention provides a hot shoe assembly 100, which is used to connect a photographic or video recording device with a functional component. The functional component can be any of the following: a flash, a flash trigger, a microphone, a remote control, or a GPS locator. The hot shoe assembly 100 of this embodiment includes a hot shoe body 1, a hot shoe connector 2, and a connector plug 3.

[0038] Specifically, the hot shoe connector 2 is disposed on the hot shoe body 1. The hot shoe connector 2 is used to connect to the photography and videography equipment. The connector 3 is disposed on the hot shoe connector 2, and the connector 3 enables the hot shoe connector 2 to be detachably fixed to the photography and videography function, so that the hot shoe assembly 100 is detachably connected to the photography and videography function.

[0039] Please see Figures 1 to 3 As shown, in some embodiments, the hot shoe body 1 may include a housing 11 and a bottom housing 12. The housing 11 may cover the bottom housing 12 so that an installation space can be formed inside the hot shoe body 1, and the installation space may be formed between the housing 11 and the bottom housing 12. The installation space may be used to accommodate functional components so that the functional components can be connected to the photographic or video-recording equipment via the hot shoe connector 2.

[0040] In some embodiments, the housing 11 may be provided with a light emission port 111. The light emission port 111 may be connected to the installation space. The installation space is provided with a light source 112, which is arranged corresponding to the light emission port 111. The flash light emitted by the light source 112 can be emitted from the light emission port 111.

[0041] In some embodiments, the hot shoe body 1 may include a capacitor 13, which may be housed within the mounting space. The light source 112 may be a xenon lamp or an LED lamp. High voltage can be stored in the capacitor 13, and a pulse trigger can cause the xenon lamp or LED lamp to discharge, thereby achieving a momentary flash.

[0042] In some embodiments, a Fresnel lens 14 may be provided on the hot shoe body 1. The Fresnel lens 14 may be provided on the housing 11 and arranged on the side of the light outlet 111 away from the light source 112, so that the flash light emitted from the light outlet 111 can pass through the Fresnel lens 14 and then be emitted.

[0043] The Fresnel lens 14 is a special lens with concentric rings of increasing size engraved on its surface. When the flash light passes through the Fresnel lens 14, it is deflected to converge the flash light to a common focal point, thereby maximizing the flash light's illumination of the object's surface and effectively enhancing the illumination effect of the light source 112.

[0044] In some embodiments, the hot shoe body 1 may include a PCB board, which can be used to precisely supply power to the capacitor 13. The PCB board enables intelligent flashing on the hot shoe body 1.

[0045] Please see Figures 1 to 3 As shown, in some embodiments, the hot shoe connector 2 may include a connection terminal 24. The connection terminal 24 may be disposed on the hot shoe connector 2. Multiple connection terminals 24 may be provided. Multiple connection terminals 24 are spaced 33 apart on the side of the hot shoe connector 2 opposite to the hot shoe body 1. The hot shoe connector 2 is used for fixed connection with photographic / video recording equipment, and the connection terminals 24 are used for electrical connection with the photographic / video recording equipment.

[0046] Please see Figures 2 to 6 As shown, in some embodiments, the photographic / video recording device may include a hot shoe 200. The hot shoe 200 may be provided with probes 202. Multiple probes 202 may be provided. Multiple connection terminals 24 may be correspondingly provided with multiple probes 202. When the hot shoe connector 2 is fixedly connected to the photographic / video recording device, the multiple connection terminals 24 are electrically connected to the multiple probes 202 respectively, thereby realizing the electrical signal connection between the hot shoe assembly 100 and the photographic / video recording device.

[0047] Please see Figures 1 to 3 As shown, in some embodiments, the hot shoe connector 2 may include a base 25. The base 25 may be attached to the bottom of the hot shoe body 1. The base 25 has a mounting cavity 251 with a side opening. A connection terminal 24 may be disposed within the mounting cavity 251 and protrude from the base 25. Thus, the connection terminal 24 can be connected to the hot shoe connector 2 via the base 25.

[0048] In some embodiments, the hot shoe connector 2 may include a front cover 26. The front cover 26 is fixed to the side of the connection terminal 24 facing away from the base 25 and is detachably connected to the base 25 to fix the connection terminal 24 between the front cover 26 and the base 25. At this time, the bottom surface of the connection terminal 24 extends from the side edge of the base 25 to abut against the probe 202 of the hot shoe mount 200 of the camera device, thereby realizing the electrical signal connection between the hot shoe assembly 100 and the camera device.

[0049] In some embodiments, the base 25 and the front cover 26 may be made of a high-strength metal material to ensure structural stability during repeated insertion and removal from the hot shoe 200 of the camera device. The base 25 has a side-opening mounting cavity 251, which facilitates direct installation of the connection terminal 24 from the side, thereby effectively improving assembly efficiency.

[0050] In some embodiments, the front cover 26 is fixed to the side of the connecting terminal 24 away from the base 25 and is detachably snapped into the base 25. In this example, the mounting cavity 251 is an "L"-shaped semi-enclosed mounting cavity. The hot shoe connector 2 may include an insulating base 27. A plurality of connecting terminals 24 are spaced apart and inserted into the insulating base 278, which has an L-shaped structure. One end of the connecting terminal 24 protrudes downward from the bottom surface of the insulating base 27 (the horizontal part of the L-shaped structure) and extends to the outside of the base 25 for electrical connection with the hot shoe contacts on the camera. The other end of the connecting terminal 24 extends into the insulating housing and extends longitudinally near the top of the L-shaped structure of the insulating base 27 for electrical connection with the functional circuitry within the hot shoe body 1. After the connecting terminal 24 is inserted into the insulating base 27 and fixed, the insulating base 27 is housed in the mounting cavity 251 of the base 25, and then the front cover 26 is mated and fixed to the base 25, so that the connecting terminal 24 is securely clamped between the two. It avoids displacement of the connecting terminal 24 due to vibration or external force during use. With this clamping and fixing method, no additional gluing or welding is required, which is convenient for disassembly and assembly and reduces manufacturing complexity.

[0051] Please see Figures 4 to 6 As shown, in some embodiments, the connector 3 can be disposed on the hot shoe connector 2 and arranged on one side of the connector terminal 24. Specifically, the connector 3 can be disposed on the base 25. In the photographic or video-recording equipment, the hot shoe base 200 can be provided with a support groove 2011. The connector 3 on the hot shoe connector 2 slides relative to the hot shoe base 200 along a preset installation direction and slides into the support groove 2011 along the preset installation direction, thereby realizing the connection between the hot shoe base 200 and the connector 3. Thus, the hot shoe connector 2 and the hot shoe body 1 can be installed on the photographic or video-recording equipment.

[0052] Please see Figure 6 As shown, in some embodiments, the hot shoe 200 can be plate-shaped. The hot shoe 200 can be disposed on the top of the photographic or video-recording equipment. The support groove 2011 can be formed on the top surface of the hot shoe 200. The top surface and side surface of the support groove 2011 can have openings. When the connector 3 slides along a preset installation direction, the connector 3 can extend into the support groove 2011 through the side opening and engage with the support groove 2011, thereby realizing the connection between the connector 3 and the support groove 2011.

[0053] Please see Figures 4 to 7As shown, in some embodiments, a first support portion 2012 is formed on the inner sidewall of the support groove 2011 corresponding to the hot shoe 200. The first support portion 2012 may be located at the end of the support groove 2011 away from the center. The first support portion 2012 may be located at the bottom of the support groove 2011. The connector 3 includes a first connecting portion 31. When the connector 3 is inserted into the hot shoe 200, the first connecting portion 31 is inserted into the support groove 2011, and the outer wall of the first connecting portion 31 is in contact with the top surface of the first support portion 2012. Thus, the first connecting portion 31 and the top surface of the first support portion 2012 are fully in contact, thereby achieving a tight connection between the first connecting portion 31 and the first support portion 2012 and improving the connection stability between the first connecting portion 31 and the first support portion 2012.

[0054] In some embodiments, a second support portion 2013 is formed on the inner sidewall of the hot shoe holder 200 corresponding to the support groove 2011. The second support portion 2013 and the first support portion 2012 may be arranged in a stepped manner. The second support portion 2013 may be located on the side of the first support portion 2012 near the center of the support groove 2011. The connector 3 may include a second connecting portion 32. The second connecting portion 32 is connected to the first connecting portion 31. The first connecting portion 31 and the second connecting portion 32 are arranged in a stepped manner. When the connector 3 is inserted into the hot shoe holder 200, the second connecting portion 32 is inserted into the support groove 2011, and a gap 33 is provided between the outer wall of the second connecting portion 32 and the sidewall of the second support portion 2013. Therefore, by using the interval 33, the outer wall of the second connecting part 32 and the side wall of the second support part 2013 are not fully fitted, thereby reducing the contact area between the second connecting part 32 and the second support part 2013, thereby reducing the friction and wear between the second connecting part 32 and the second support part 2013 during installation, and further reducing the friction and wear between the connecting plug 3 and the support groove 2011 during installation.

[0055] In some embodiments, the extension direction of the first connecting portion 31 is perpendicular to a preset installation direction. Thus, the first connecting portion 31 extends toward the installation direction perpendicular to the connecting plug 3.

[0056] In some embodiments, the extension direction of the second connecting portion 32 is perpendicular to a preset installation direction, and the extension direction of the first connecting portion 31 is perpendicular to the extension direction of the second connecting portion 32. Therefore, when the first connecting portion 31 extends into the support groove 2011 and abuts against the first support portion 2012, the connection between the first connecting portion 31 and the first support portion 2012 effectively limits the connection plug 3 to the support groove 2011 laterally, thereby preventing the connection plug 3 from becoming loose laterally. When the second connecting portion 32 extends into the support groove 2011 and abuts against the second support portion 2013, the insertion of the second connecting portion 32 into the support groove 2011 allows the second connecting portion 32 and the second support portion 2013 to partially abut against each other, effectively limiting the connection plug 3 to the support groove 2011 vertically, thereby preventing the connection plug 3 from becoming loose vertically.

[0057] In some embodiments, the connector 3 may be made of a high-strength metal material to ensure structural stability during repeated insertion and removal from the support slot 2011 of the camera device. Therefore, even if the outer wall of the second connector 32 and the side wall of the second support 2013 are not fully fitted, the use of a metal material can maintain high structural strength and prevent damage to the second connector 32 and the second support 2013 due to frequent insertion and removal.

[0058] It should be noted that in some other embodiments, the connector 3 may also be made of plastic.

[0059] It should also be noted that in some other embodiments, the connector 3 may also be made of a metal and plastic structure.

[0060] In some embodiments, two connectors 3 may be provided. The two connectors 3 may be located on opposite sides of the connector terminal 24. The two ends of the support groove 2011 relative to the hot shoe seat 200 are respectively located at the first support portion 2012 and the second support portion 2013. The two first support portions 2012 are respectively connected to the two first connecting portions 31. The second support portions 2013 are respectively arranged corresponding to the two second first connecting portions 31, and respectively arranged corresponding to the two second connecting portions 32. Thus, the two connectors 3 can extend into the support groove 2011 and abut against the two first support portions 2012 and the two second support portions 2013, thereby improving the stability between the connectors 3 and the support groove 2011.

[0061] Please see Figure 2 As shown, in some embodiments, the connector 3 body can be made of metal. A bayonet can be provided on the inner wall of the connector 3. A plastic component can be installed within the bayonet, thereby maintaining high structural strength of the connector 3 and preventing damage due to frequent plugging and unplugging.

[0062] Please see Figures 8 to 10 As shown, in some other embodiments, the second connecting portion 32 may have a main body portion and a stepped portion 321. The stepped portion 321 is located on the side of the main body portion near the second support portion 2013. The end of the stepped portion 321 near the second support portion 2013 abuts against the side wall of the second support portion 2013. A stepped groove 3211 is formed between the stepped portion 321 and the side wall of the second support portion 2013, and the stepped groove 3211 forms a gap 33. Thus, the stepped groove 3211 prevents the outer wall of the second connecting portion 32 from being fully fitted with the side wall of the second support portion 2013, thereby reducing the contact area between the second connecting portion 32 and the second support portion 2013. This reduces friction and wear between the second connecting portion 32 and the second support portion 2013 during installation, and further reduces friction and wear between the connector 3 and the support groove 2011 during installation.

[0063] In some embodiments, the end of the step portion 321 near the second support portion 2013 abuts against the second support portion 2013, such that at least a portion of the step portion 321 can abut against the second support portion 2013. Therefore, compared to not abutting against the second support portion 2013 at all, there is a support point between the step portion 321 and the second support portion 2013, which makes the structure between the step portion 321 and the second support portion 2013 more stable.

[0064] It should be noted that in some embodiments, multiple steps 321 may be provided. Multiple steps 321 may be arranged at intervals 33 on the side of the second connecting portion 32 near the second support portion 2013. Multiple steps 321 may be arranged in a stepped manner. Multiple steps 321 simultaneously abut against the second support portion 2013, thereby further improving the structural stability between the multiple steps 321 and the second support portion 2013.

[0065] Please see Figures 11 to 13 As shown, in some other embodiments, the second connecting portion 32 is provided with an arc-shaped portion 322. The opposite ends of the arc-shaped portion 322 abut against the second support portion 2013, and the arc-shaped portion 322 is recessed in a direction away from the second support portion 2013, forming a gap 33. Therefore, by utilizing the arc-shaped portion 322, the outer wall of the second connecting portion 32 and the side wall of the second support portion 2013 are not fully fitted, thereby reducing the contact area between the second connecting portion 32 and the second support portion 2013. This reduces friction and wear between the second support portion 2013 and the second support portion 2013 during installation, and consequently reduces friction and wear between the connecting plug 3 and the support groove 2011 during installation.

[0066] In some embodiments, the arc-shaped portion 322 is easier to process than the stepped portion 321. Therefore, the processing efficiency of the second connecting portion 32 of the connector 3 can be improved by using the arc-shaped portion 322, thereby reducing the processing cost of the second connecting portion 32.

[0067] In some embodiments, the two opposite ends of the arc-shaped portion 322 abut against the second support portion 2013, so that support points can be provided between the two ends of the arc-shaped portion 322 and the second support portion 2013, thereby making the structure between the arc-shaped portion 322 and the second support portion 2013 more stable.

[0068] It should be noted that in some embodiments, multiple arc-shaped portions 322 may be provided. Multiple arc-shaped portions 322 may be arranged at intervals 33 on the side of the second connecting portion 32 near the second support portion 2013. Multiple arc-shaped portions 322 may be arranged in a stepped manner. The ends of multiple arc-shaped portions 322 may simultaneously abut against the second support portion 2013, thereby further improving the structural stability between the multiple arc-shaped portions 322 and the second support portion 2013.

[0069] Please see Figure 14 As shown, in other embodiments, the second connecting portion 32 is provided with a spherical portion 323, which protrudes from the second connecting portion 32 toward the direction close to the second support portion 2013. One end of the spherical portion 323 away from the second connecting portion 32 abuts against the side wall of the second support portion 2013. The spherical portion 323 includes an abutting wall 3231 for abutting against the side wall of the second support portion 2013 and an arcuate wall 3232 opposite to the side wall of the second support portion 2013. The arcuate wall 3232 and the side wall of the second support portion 2013 form the gap 33. Therefore, by utilizing the gap 33 formed between the arc-shaped wall 3232 and the side wall of the second support 2013, the outer wall of the second connecting part 32 and the side wall of the second support 2013 are not fully fitted together, thereby reducing the contact area between the second connecting part 32 and the second support 2013. This reduces the friction and wear between the second connecting part 32 and the second support 2013 during installation, and further reduces the friction and wear between the connecting plug 3 and the support groove 2011 during installation.

[0070] Please see Figure 15As shown, in other embodiments, the second connecting portion 32 is provided with an abutment portion 324, which extends from the second connecting portion 32 toward the direction close to the second support portion 2013. The abutment portion 324 includes a first end and a second end disposed opposite to each other. The first end is connected to the second connecting portion 32, and the second end abuts against the side wall of the second support portion 2013. The cross-sectional area of ​​the abutment portion 324 gradually decreases in the direction from the first end to the second end, and a gap 33 is formed between the side wall between the first end and the second end of the abutment portion 324 and the side wall of the second support portion 2013. Thus, by not fully fitting the side wall between the first end and the second end of the abutment portion 324 and the side wall of the second support portion 2013, the contact area between the second connecting portion 32 and the second support portion 2013 can be reduced, thereby reducing friction and wear between the second connecting portion 32 and the second support portion 2013 during installation, and further reducing friction and wear between the connector plug 3 and the support groove 2011 during installation.

[0071] Please see Figure 16 As shown, in other embodiments, the second connecting portion 32 is provided with a plurality of toothed portions 325 arranged at intervals 33. The plurality of toothed portions 325 extend toward the direction close to the second support portion 2013, and abut against the sidewall of the second support portion 2013. A groove 3251 is formed between two adjacent toothed portions 325, and the plurality of grooves 3251 are spaced 33 in the area corresponding to the sidewall of the second support portion 2013. Thus, by using the plurality of grooves 3251 to form intervals 33 in the area corresponding to the sidewall of the second support portion 2013, the plurality of toothed portions 325 are not fully fitted with the sidewall of the second support portion 2013, thereby reducing the contact area between the second connecting portion 32 and the second support portion 2013, thereby reducing the friction and wear between the second connecting portion 32 and the second support portion 2013 during installation, and further reducing the friction and wear between the connector 3 and the support groove 2011 during installation.

[0072] In some embodiments, a plurality of toothed portions 325 may be arranged at intervals 33 on the side of the second connecting portion 32 near the second support portion 2013. The plurality of toothed portions 325 may be arranged in a stepped manner. The ends of the plurality of toothed portions 325 may simultaneously abut against the sidewall of the second support portion 2013, thereby further improving the structural stability between the plurality of toothed portions 325 and the second support portion 2013.

[0073] Please see Figure 2As shown, in some embodiments, the hot shoe assembly 100 may include a locking pin 21. The locking pin 21 is slidable relative to the hot shoe connector 2 to extend or retract the hot shoe connector 2. The hot shoe mount 200 of the camera / video equipment may be provided with a locking hole 203. During the installation of the hot shoe assembly 100 on the camera / video equipment, the locking pin 21 can retract the hot shoe connector 2 to achieve electrical connection between the hot shoe assembly 100 and the camera / video equipment. When the hot shoe assembly 100 is installed on the camera / video equipment, the locking pin 21 can be positioned opposite the locking hole 203, thereby extending the locking pin 21 out of the hot shoe connector 2 to lock the hot shoe assembly 100 to the hot shoe mount 200 of the camera / video equipment.

[0074] In some embodiments, the hot shoe assembly 100 may include an unlock button 22. The unlock button 22 is used to push the locking pin 21 back into the hot shoe connector 2. During the installation of the hot shoe assembly 100 on the hot shoe mount 200 of the camera device, the user can press the unlock button 22 to retract the locking pin 21 into the hot shoe connector 2, thereby enabling the hot shoe assembly 100 to be electrically connected to the camera device.

[0075] In some embodiments, the hot shoe assembly 100 may include an elastic element 23. The elastic element 23 may be disposed between the unlock button 22 and the locking pin 21. One end of the elastic element 23 may abut against the unlock button 22, and the other end of the elastic element 23 may abut against the locking pin 21. During the installation of the hot shoe assembly 100 on the camera device, the user can press the unlock button 22 to retract the elastic element 23, thereby causing the locking pin 21 to retract into the hot shoe connector 2. When the hot shoe assembly 100 is electrically connected to the camera device, the user releases the unlock button 22, the elastic element 23 can reset and push the unlock button 22 to move in the opposite direction, causing the locking pin 21 to extend out of the hot shoe connector 2, thereby locking the hot shoe assembly 100 to the hot shoe mount 200 of the camera device.

[0076] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: This invention provides a hot shoe assembly 100 and a photographic system. The hot shoe assembly 100 can be connected to photographic and video recording equipment. A connector 3 is provided on the hot shoe connection portion. The connector 3 includes a first connecting portion 31 and a second connecting portion 32 connected together, with the first connecting portion 31 and the second connecting portion 32 arranged in a stepped manner. When the connector 3 is inserted into the hot shoe base 200, the first connecting portion 31 is inserted into the support groove 2011, and the outer wall of the first connecting portion 31 is in contact with the first support portion 2012. The second connecting portion 32 is inserted into the support groove 2011, and a gap 33 is provided between the outer wall of the second connecting portion 32 and the second support portion 2013. Thus, the gap 33 prevents the outer wall of the second connecting portion 32 from being fully in contact with the second support portion 2013, thereby reducing the contact area between the second connecting portion 32 and the second support portion 2013. This reduces friction and wear between the second connecting portion 32 and the second support portion 2013 during installation, and consequently reduces friction and wear between the connector 3 and the support groove 2011 during installation.
