Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a photography and videography accessory and electronic equipment. Background Technology

[0002] In the field of electronic equipment and accessory connections, various solutions have been proposed to simultaneously achieve the functions of arranging multiple connection terminals, protecting terminals, and positioning components within a limited space. Some solutions involve setting protruding structures along the height direction on both sides of the connection terminal's width, and designing an inclined surface on the side of the protruding structure away from the terminal. This inclined surface decomposes external forces such as impacts and compressions into components along the inclined direction and perpendicular to the inclined direction, thereby reducing the direct impact of external forces on the surrounding structure of the terminal. Simultaneously, by adjusting the thickness distribution at the interface with the accessory, the system adapts to the stress requirements during installation, thus balancing the terminal arrangement space and installation stability to a certain extent.

[0003] However, in such solutions, the load-bearing structures directly associated with the terminals (such as protrusion structures and terminal retaining structures) are often made of a single plastic material, and their structural strength is highly dependent on the external force decomposition effect of the inclined surface. If the wall thickness of the plastic structure is reduced to accommodate a more compact internal space of the equipment, or if the inclined surface design is omitted to simplify the processing flow and control production costs, the deformation resistance and fatigue resistance of the plastic structure will significantly decrease. During the frequent insertion and removal of electronic equipment and accessories (such as accessories being repeatedly installed on or removed from electronic equipment), the plastic structures on both sides of the terminals are prone to cracking and deformation due to the impact load during insertion and removal and the stress accumulated over long-term use. This may not only lead to poor terminal contact and affect the reliability of electrical connections, but in severe cases, it may also cause damage to the overall connection structure, making it difficult to meet the durability requirements of long-term frequent use.

[0004] Therefore, how to improve the resistance to insertion and extraction damage of the structures on both sides of the terminal while ensuring the compactness of the connection structure and ease of processing has become a technical problem that urgently needs to be solved in this field.

[0029] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] See Figures 1 to 3One embodiment of this application provides a photography and videography accessory 100, which includes an accessory body 10, a connector 20, a fixing base 30, and an electrical connector 40.

[0033] The connecting seat 20 is a metal part and is located at the bottom of the accessory body 10. The connecting seat 20 includes a seat body 21 and connecting arms 22 disposed on the seat body 21. The seat body 21 forms a mounting area 210, and connecting arms 22 are respectively provided on both sides of the seat body 21 corresponding to the mounting area 210. Each connecting arm 22 has a receiving portion 220. The fixing seat 30 is a plastic part and is located in the mounting area 210. The fixing seat 30 includes a fixing body 31 and fixing arms 32 disposed on both sides of the fixing body 31. In the height direction of the photographic / videography accessory 100, the outer surface of the fixing arm 32 is a vertical surface 321, and the fixing arm 32 is disposed in the receiving portion 220. The electrical connector 40 is disposed on the fixing body 31 and arranged in the mounting area 210. One end of the electrical connector 40 extends outward from the connecting seat 20 to be electrically connected to the hot shoe on the photographic / videography device.

[0034] For the photography and videography accessory 100 of this application, the connector 20 is a metal part. The metal connector 20 is the main support structure of the photography and videography accessory 100. In scenarios where the photography and videography accessory 100 is frequently plugged and unplugged from the photography and videography device, it can effectively absorb the impact energy during plugging and unplugging, and prevent the structure around the electrical connector 40 from cracking due to stress concentration. In addition, the main body 21 of the connector 20 and the connecting arm 22 can form a rigid frame. The connecting arms 22 on both sides of the mounting area 210 cooperate with the fixing seat 30 through the receiving part 220, and the plugging and unplugging force is directly transmitted to the accessory body 10 through the metal connector 20, reducing the direct force on the plastic fixing seat 30. Furthermore, the vertical surface 321 design of this application can make the fixing arm 32 and the receiving part 220 of the connecting arm 22 form a vertical contact, so that the external force is directly transmitted through the metal connector 20, effectively avoiding stress cycle damage, significantly improving the anti-plugging and unplugging damage capability of the structure on both sides of the electrical connector 40, and ensuring the stability and service life of the overall structure of the photography and videography accessory 100.

[0035] In the photography and videography accessory 100 of this application, the accessory body 10 can be at least one of a flash unit, a photography and videography light unit, and a microphone unit. The accessory body 10 includes a housing 11 and a main control circuit board 12 disposed inside the housing 11. The main control circuit board 12 is electrically connected to the end of the electrical connector 40 disposed in the connector 20. The following description will take the accessory body 10 as a flash unit as an example.

[0036] Combination Figure 2 and Figure 3As shown, in some embodiments of this application, the outer casing 11 may include a main casing 111 and a bottom casing 112 disposed at the bottom of the main casing 111. The outer contour of the main casing 111 is rectangular, and the bottom casing 112 is disposed at the bottom of the main casing 111 and encloses the main casing 111 to form an assembly space, and the main control circuit board 12 is disposed in the assembly space.

[0037] In this embodiment, a flash window 113 is provided on one side of the main housing 111. The accessory body 10 may also include a flash tube 13, which is disposed in the assembly space and corresponding to the flash window 113. In some examples, the accessory body 10 may also include a reflector 14, a capacitor 15, and a battery 16, all of which are disposed in the assembly space. The reflector 14 is disposed corresponding to the flash tube 13 and is used to reflect the flash light emitted by the flash tube 13 so that the flash light can be effectively emitted from the flash window 113, ensuring an effective light output rate for the accessory body 10.

[0038] In addition, the accessory body 10 may also include a Fresnel lens 17, which can be set at the flash window 113 of the main housing 111 to process the flash light and improve the uniformity of the light output of the accessory body 10.

[0039] In some embodiments of this application, the bottom of the base shell 112 is provided with an opening that communicates with the assembly space. The connecting seat 20 is accommodated in the assembly space by the opening portion of the base shell 112, and a portion of the bottom area of ​​the connecting seat 20 is arranged outside the base shell 112.

[0040] Combination Figure 3 and Figure 4 As shown in this application, the connector 20 is a metal part and is disposed at the bottom of the accessory body 10. The connector 20 includes a body 21 and a connector arm 22 disposed on the body 21. The body 21 forms an installation area 210, and the body 21 is provided with connector arms 22 on both sides corresponding to the installation area 210. The connector arms 22 are provided with receiving portions 220.

[0041] In some embodiments of this application, the seat body 21 may include a seat base plate 211, a base body 212, and two seat side plates 213. The base body 212 is disposed on the seat base plate 211, and the two seat side plates 213 are respectively disposed on both sides of the base body 212. The seat base plate 211, the base body 212, and the seat side plates 213 can enclose and form a mounting area 210 with a side opening, and the mounting area 210 is in a semi-open state.

[0042] The semi-open installation area 210 allows the mounting base 30 to be pushed in laterally through the side opening without forced compression, effectively reducing assembly time, simplifying assembly, and improving production efficiency. Furthermore, this design prevents the plastic mounting base 30 from breaking, ensuring structural stability. In addition, the enclosure structure formed by the base plate 211, the base body 212, and the side plate 213 ensures accurate positioning and prevents the electrical connector 40 from shifting.

[0043] Connecting arms 22 are disposed on the side of the base plate 211, and two connecting arms 22 are respectively arranged corresponding to two side plates 213. Each connecting arm 22 is provided with a receiving part 220, which can be a through hole structure or a blind hole structure, and the receiving parts 220 on the two connecting arms 22 are arranged correspondingly.

[0044] Two connecting arms 22 are respectively arranged corresponding to two seat side plates 213, and the receiving portions 220 of the two connecting arms 22 can form symmetrical force-bearing points. The two fixing arms 32 of the fixing seat 30 are respectively embedded in the receiving portions 220. When the camera accessory 100 is inserted or removed from the camera device, the lateral force can be distributed to the connecting arms 22 on both sides through the receiving portions 220, rather than concentrated on one fixing arm 32. This design can reduce stress concentration on the fixing arm 32, prevent the plastic fixing arm 32 from cracking due to excessive force on one side, and ensure the overall structural stability of the camera accessory 100.

[0045] In some examples, the connecting arm 22 may include an arm body 221 and a stop portion 222 disposed at one end of the arm body 221. The end of the arm body 221 away from the stop portion 222 is fixed to the seat body 21. The stop portion 222, the arm body 221, and the side of the seat body 21 enclose each other to form a receiving portion 220.

[0046] The stop part 222, the arm body 221, and the side of the seat body 21 can be enclosed to form a three-sided enclosed receiving part 220, which can retain a bottom opening for the fixed arm 32 to be inserted, thereby restricting the displacement of the fixed seat 30 in the front and back directions, preventing the fixed seat 30 from being pushed forward or retracted backward when plugged in or unplugged, so as to ensure effective docking and electrical connection between the photography and videography accessory 100 and the hot shoe on the photography and videography device.

[0047] In this example, the outer side of the arm body 221 extends outward beyond the outer side of the stop portion 222. Because the outer side of the arm body 221 extends beyond the stop portion 222, when the camera accessory 100 is inserted into the hot shoe of the camera device, the extended outer side of the arm body 221 can contact the inner wall of the hot shoe to form a guide, facilitating the insertion and removal of the camera accessory 100 relative to the camera device.

[0048] In addition, such as Figure 5As shown, the camera / video recording device 200 includes a hot shoe mount 201, which has an electrical connection terminal 202 that mates with the electrical connector 40 to form an electrical connection. The hot shoe mount 201 has a hot shoe groove for mounting the camera / video recording accessory 100. The inner sidewall of the hot shoe groove has a horizontal step surface 2011 and a sloped step surface 2012 arranged in a stepped manner.

[0049] When the photography and videography accessory 100 is detachably connected to the hot shoe mount 201 of the photography and videography device 200, the outer side of the arm body 221 can overlap the horizontal step surface 2011 of the hot shoe groove, so that the horizontal step surface 2011 of the hot shoe groove supports the arm body 221, effectively buffering the force on the fixed arm 32 and further enhancing the stability of the structure.

[0050] In some embodiments of this application, the photography and videography accessory 100 may further include a front cover 50, which is a metal part. The front cover 50 may be disposed on the side of the fixing base 30 opposite to the connecting base 20, and the front cover 50 may be snapped and fixed to the connecting base 20 to form a detachable connection with the connecting base 20.

[0051] During actual installation, the electrical connector 40 can be first fixed on the mounting base 30, then the mounting base 30 with the electrical connector 40 installed can be placed in the mounting area 210 of the connector 20, and then the front cover 50 can be mated with the connector 20 so that the electrical connector 40 is stably fixed between the mounting base 30 and the connector 20.

[0052] This configuration allows the electrical connector 40 to be effectively fixed on the mounting base 30 and the connecting base 20, preventing the electrical connector 40 from shifting due to vibration or external force during use. Furthermore, this installation method eliminates the need for additional gluing or welding, effectively reducing processing difficulty and facilitating installation, disassembly, and maintenance.

[0053] Combination Figure 3 , Figure 7 as well as Figure 8 As shown in this application, the mounting area 210 of the connector 20 is provided with a fixing seat 30, which is used to mount the electrical connector 40. The fixing seat 30 is a plastic part and includes a fixing body 31 and fixing arms 32 disposed on both sides of the fixing body 31. In the height direction of the camera accessory 100, the outer surface of the fixing arm 32 is a vertical surface 321, and the fixing arm 32 is disposed in the receiving portion 220.

[0054] In some examples of this application, the fixing body 31 may include a seat 311 and a mounting part 312 provided at one end of the seat 311 in the length direction, and fixing arms 32 are provided on both sides of the seat 311.

[0055] The mounting part 312 has multiple isolated mounting cavities 314 inside, and the bottom surface of the base part 311 has multiple mounting grooves 313 extending along the length of the base part 311. The multiple mounting cavities 314 and the multiple mounting grooves 313 are connected one-to-one to form multiple mounting spaces, which are used to install electrical connectors 40.

[0056] In some examples, the electrical connector 40 includes a first connecting portion 41 and a second connecting portion 42, which are connected at an included angle. The first connecting portion 41 is housed in a mounting cavity 314, and the second connecting portion 42 is housed in a mounting groove 313. The end of the second connecting portion 42 extends outward from the connector 20 and is used for electrical connection with a hot shoe on a camera device.

[0057] The mounting base 30 is made of plastic, and the electrical connector 40 is set in the installation space of the mounting base 30, which can completely isolate the electrical connector 40 from the metal connector 20. At the same time, the multiple mounting cavities 314 are isolated from each other, which can further prevent leakage between different electrical connectors 40 and eliminate the risk of short circuit.

[0058] Furthermore, the metal connector 20 can wrap around the fixing arm 32 through the receiving part 220, forming a rigid protection to effectively withstand the impact and collision force of insertion and removal, preventing the plastic fixing arm 30 from being directly subjected to force. If the camera device connected to the camera accessory 100 is accidentally dropped, the metal connector 20 can protect the deformation of the fixing arm 30, ensuring that the electrical connector 40 does not shift, and ensuring that the electrical connector 40 can still maintain normal electrical connection after the fall, avoiding electrical connection failure.

[0059] In some examples, the mounting base 30 may also include a mounting post 33 disposed on the top surface of the base body 311, which can be used to fix it to the front cover 50.

[0060] The mounting post 33 has a mounting hole 331, and the front cover 50 has a cover hole at the corresponding position. When the front cover 50 is assembled with the connecting seat 20, the cover hole of the front cover 50 can correspond to the mounting hole 331 of the mounting post 33 on the fixed seat 30 placed in the mounting area 210 of the connecting seat 20. The fastener 60 passes through the corresponding mounting hole 331 and cover hole, so that the front cover 50 and the fixed seat 30 can be fixedly connected.

[0061] The fastener 60 can be a screw or a pin. By fixing the front cover 50 to the fixing seat 30, the fixing seat 30 can be further locked between the front cover 50 and the connecting seat 20, so as to achieve stable assembly of the electrical connector 40 installed on the fixing seat 30 and ensure the stability of the electrical connection.

[0062] See Figure 6 , Figure 7 as well as Figure 9 In some embodiments of this application, the fixing arm 32 includes a fixing part 322 and an extension part 323 connected to one end of the fixing part 322. The end of the fixing part 322 away from the extension part 323 is connected to the side of the fixing body 31, and the outer side of the extension part 323 is a vertical surface 321.

[0063] The fixing part 322 is directly connected to the side of the fixing body 31, which can strengthen the end connection strength of the fixing arm 32 and reduce the risk of breakage. When the camera accessory 100 is inserted or removed, the lateral force borne by the extension part 323 can be distributed to the fixing body 31 through the fixing part 322, rather than being concentrated in a specific position, effectively extending the service life of the fixing arm 32.

[0064] The bottom surface of the arm body 221 of the connecting arm 22 is recessed at the position corresponding to the receiving portion 220, and the fixed arm 32 can be received in the receiving portion 220 through the notch 223. The width of the notch 223 is greater than the thickness of the fixed arm 32, and there is a gap between the outer side of the fixed arm 32 and the inner side of the arm body 221 corresponding to the notch 223.

[0065] The gap between the notch 223 and the fixed arm 32 can accommodate thermal expansion and contraction, allowing the expansion of the plastic fixed arm 32 to avoid the risk of cracking or deformation of the fixed arm 32 due to expansion and compression, thus preventing structural damage. Furthermore, the gap provides a buffer space when the camera accessory 100 is plugged in or unplugged, preventing direct rigid collision between the fixed arm 32 and the inner surface of the notch 223, effectively buffering the impact of plugging and unplugging, and ensuring the overall structural stability of the camera accessory 100.

[0066] In some examples, such as Figure 10 As shown, the bottom end of the extension 323 is chamfered. The bottom end face of the extension 323 includes a main surface 3231 and an inner extension surface 3232 and an outer extension surface 3233 disposed on both sides of the main surface 3231. The chamfer radius formed by the inner extension surface 3232 and the outer extension surface 3233 is the same as that formed by the main surface 3231.

[0067] In this example, the inner extension surface 3232 and the outer extension surface 3233 have the same chamfer curvature as the main body surface 3231, which makes the stress distribution on both sides of the bottom end of the extension 323 completely symmetrical. This avoids the problem of excessive stress on one side and excessive stress on the other side due to different curvature on one side, so as to effectively buffer the insertion and removal impact force, reduce the risk of cracking at the bottom end of the extension 323, and improve the fatigue life of the fixed arm 32.

[0068] like Figure 3As shown, in some embodiments of this application, the photography and videography accessory 100 may further include a locking member 70 and an unlocking member 80. The locking member 70 is disposed on the connecting seat 20, and has a locking pin 71. The end of the locking pin 71 can extend from the bottom surface of the seat base plate 211, and the end of the locking pin 71 extending from the bottom surface of the seat base plate 211 can engage with the locking hole in the hot shoe of the photography and videography device to form a locking fixation.

[0069] In this embodiment, the unlocking member 80 is provided with an abutting slope that cooperates with the locking member 70, and a spring 90 is provided between the unlocking member 80 and the locking member 70. The unlocking member 80 can move relative to the locking member 70. When the user presses the unlocking member 80, the spring 90 is compressed, and under the guidance of the abutting slope, the locking pin 71 of the locking member 70 can move upward to retract into the interior of the base body 212, thereby unlocking the locking pin 71 from the locking hole in the hot shoe of the camera device, thus allowing the accessory shoe 100 to be removed from the camera device.

[0070] After the user releases the pressure on the unlocking member 80, the spring 90 located between the unlocking member 80 and the locking member 70 can restore its elastic deformation to drive the unlocking member 80 to reset, so that the end of the locking pin 71 on the locking member 70 extends out of the base plate 211, so that the end of the locking pin 71 can mate with the locking hole in the hot shoe of the camera device.

[0071] In addition, one embodiment of this application also provides an electronic device, which includes a camera and a camera accessory 100. The camera accessory 100 is detachably connected to the hot shoe of the camera and the camera device, and the electrical connector 40 is capable of forming an electrical connection with the hot shoe.

[0072] For the photographic and video-enhancing accessories and electronic devices of this application, the connector of the photographic and video-enhancing accessories is a metal part. The metal connector is the main support structure of the photographic and video-enhancing accessories. In scenarios where the photographic and video-enhancing accessories are frequently plugged and unplugged from the photographic and video-enhancing devices, it can effectively absorb the impact energy during plugging and unplugging, and prevent the surrounding structure of the electrical connector from cracking due to stress concentration. In addition, the main body of the connector and the connecting arm can form a rigid frame. The connecting arms on both sides of the mounting area cooperate with the fixing seat through the receiving part, and the plugging and unplugging force is directly transmitted to the accessory body through the metal connector, reducing the direct force on the plastic fixing seat. Furthermore, the vertical surface design of this application can make the fixing arm and the receiving part of the connecting arm form a vertical contact, so that the external force is directly transmitted through the metal connector, effectively avoiding stress cycle damage, significantly improving the anti-plugging and unplugging damage capability of the structure on both sides of the electrical connector, and ensuring the stability and service life of the overall structure of the photographic and video-enhancing accessories.

[0073] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
