[0024] Please see Figures 1 to 9 This utility model provides a shooting accessory 10, including an accessory body 12 and a back plate 14 connected to the accessory body 12. The accessory body 12 is used to connect to an electronic product with shooting function, such as a mobile phone or tablet. When the shooting accessory 10 is connected to the electronic product through the accessory body 12, the back plate 14 corresponds to the position of the camera on the electronic product. The back plate 14 is used for mounting photography and videography auxiliary equipment 16, such as a lens. Thus, the photography and videography auxiliary equipment 16 is indirectly mounted on the electronic product using the shooting accessory 10. This application takes a mobile phone as the electronic product and a lens as the photography and videography auxiliary equipment 16 as an example. After the lens is mounted to the mobile phone through the shooting accessory 10, the lens is set directly opposite the camera of the mobile phone to assist the mobile phone in shooting.

[0025] The back panel 14 is provided with a mounting port 18, and the photography and videography auxiliary equipment 16 is connected to the back panel 14 through the mounting port 18, thereby fixing the photography and videography auxiliary equipment 16 to the back panel 14.

[0026] The specific method by which the lens is mounted to the back plate 14 via the mounting port 18 is not limited; for example, it can be a snap-fit ​​or a threaded fit. The mounting port 18 can be set according to the type of lens. In this embodiment, the lens is a T-mount lens, the mounting port 18 is a T-mount, and the T-mount lens is snap-fitted to the back plate 14 via the T-mount.

[0027] In one embodiment, the back plate 14 is provided with a first connecting structure, and the accessory body 12 is provided with a second connecting structure adapted to the first connecting structure. The back plate 14 is detachably installed to the accessory body 12 through the cooperation of the first and second connecting structures. The back plate 14 and the accessory body 12 are detachable through the cooperation of the first and second connecting structures, so that the back plate 14 does not require tools during installation and removal, making the installation and removal operations relatively simple, so as to achieve quick installation and removal, and facilitate users to replace the back plate 14 when it is damaged.

[0028] The specific way the first and second connecting structures are matched is not limited. For example, they can be matched by snap-fit, sliding, magnetic attraction, etc., as long as they can achieve the effect of tool-free installation and removal of the back panel 14.

[0029] In this application, the first connecting structure and the second connecting structure slide together to achieve a detachable effect. The user can drive the back plate 14 to slide relative to the accessory body 12 in different directions to install the back plate 14 on the accessory body 12 or remove the back plate 14 from the accessory body 12. The operation is simple and convenient for the user.

[0030] One of the first and second connecting structures includes a sliding groove 20, and the other includes a mounting portion 22 adapted to the sliding groove 20. The mounting portion 22 is slidably inserted into the sliding groove 20, thereby mounting the back plate 14 onto the mounting portion 22 of the accessory body 12. The back plate 14 is mounted onto the accessory body 12 by sliding relative to it through the sliding fit between the mounting portion 22 and the sliding groove 20, or it is separated from the accessory body 12 by sliding in the opposite direction. After aligning the sliding groove 20 with the mounting portion 22, driving the back plate 14 to slide relative to the accessory body 12 in one direction allows the mounting portion 22 to be inserted into the sliding groove 20, thereby mounting the back plate 14 onto the accessory body 12. Driving the back plate 14 to slide in the opposite direction allows the mounting portion 22 to be withdrawn from the sliding groove 20, thereby separating the back plate 14 from the accessory body 12, completing the installation and removal of the back plate 14.

[0031] In this embodiment, the first connecting structure includes a sliding groove 20, and the second connecting structure includes a mounting part 22. That is, the sliding groove 20 is located on the back plate 14, and the mounting part 22 is located on the accessory body 12.

[0032] One of the inner walls of the slide groove 20 and the outer wall of the mounting part 22 is provided with a guide groove 24, and the other is provided with a guide protrusion 26 adapted to the guide groove 24. The guide protrusion 26 is movably inserted into the guide groove 24, and the extension direction of the guide groove 24 is consistent with the extension direction of the slide groove 20, which is also the sliding direction of the back plate 14. During the installation or removal of the back plate 14, as it moves relative to the accessory body 12, the guide protrusion 26 slides in the guide groove 24, which can play a guiding role. Moreover, after the assembly is completed, the guide groove 24 and the guide protrusion 26 cooperate to form a limiting effect in the direction perpendicular to their extension direction, enhancing the stability of the back plate 14 on the accessory body 12.

[0033] In this embodiment, the guide groove 24 is provided on the mounting part 22, and the guide protrusion 26 is provided on the inner wall of the slide groove 20.

[0034] The number of guide grooves 24 and guide protrusions 26 is not limited; there can be one or more. In this embodiment, guide grooves 24 are provided on opposite sides of the mounting part 22, and guide protrusions 26 are provided on opposite inner walls of the slide groove 20. Each guide protrusion 26 cooperates with a corresponding guide groove 24 to enhance the guiding and limiting effect.

[0035] The specific type of the main body of the accessory 12 is not limited. It can be a protective case for storing mobile phones to provide protection, or an extension frame that is attached to the outside of the mobile phone or mobile phone case.

[0036] Please see Figures 2 to 5 In one embodiment, the accessory body 12 is a protective shell, which includes a back cover 28 and a frame 30. The frame 30 surrounds the periphery of the back cover 28 and forms a receiving space with the back cover 28. The mobile phone can be stored in the receiving space to protect the mobile phone.

[0037] A clearance hole 32 is provided through the back cover 28 at the position corresponding to the camera on the electronic product. The clearance hole 32 corresponds to the camera of the mobile phone, preventing the back cover 28 from obstructing the camera. An annular protrusion is provided on the side of the back cover 28 away from the receiving space. The annular protrusion surrounds the outer periphery of the clearance hole 32 and forms the mounting part 22 of the accessory body 12. The back plate 14 is slidably mounted to the annular protrusion. When the shooting accessory 10 with the electronic product is placed on a supporting surface such as a table, the annular protrusion protrudes from the surface of the back cover, thereby increasing the distance between the camera on the electronic product and the supporting surface, reducing the risk of the camera being scratched. Moreover, the annular protrusion also serves as the mounting part 22 for the back plate 14 to be mounted, which helps to simplify the overall structure of the shooting accessory and reduce the difficulty of production. At the same time, the back plate 14 is not interfered with by the back cover 28 when sliding relative to the annular protrusion. The back plate 14 can be installed or removed by sliding along the length direction of the slide groove 20. The operation is simple and convenient for users.

[0038] The back panel 14 includes a back panel body 34 and a side portion 36 connected to one side of the back panel body 34. The back panel body 34 is located on the side of the mounting portion 22 away from the rear cover 28 and is directly opposite to the clearance hole 32. The mounting opening 18 is provided through the back panel body 34. The side portion 36 is located between the back panel body 34 and the rear cover 28 and is located on the outside of the annular protrusion.

[0039] Understandably, the groove 20 can be provided on the side of the back plate body 34 or side 36 near the annular protrusion, or the back plate body 34 and multiple side 36 can surround and form the groove 20.

[0040] In this embodiment, the outer contour of the back panel body 34 is rectangular, and there are two side portions 36. The two side portions 36 are respectively disposed on opposite sides of the back panel body 34, and the two side portions 36 are spaced apart and opposite to each other. A sliding groove 20 is formed between the two side portions 36, that is, the back panel body 34 and the two side portions 36 surround to form a sliding groove 20. An annular protrusion is slidably disposed between the two side portions 36. By aligning the sliding groove 20 with the mounting portion 22 and inserting the mounting portion 22 between the two side portions 36, the back panel 14 can be installed on the mounting portion 22. By driving the back panel 14 to slide relative to the accessory body 12, the mounting portion 22 can be withdrawn from between the two side portions 36, thereby separating the back panel 14 from the accessory body 12.

[0041] In this embodiment, the guide protrusion 26 is located on the side of the side portion 36 away from the back plate body 34 and is spaced apart from the back plate body 34. The guide groove 24 is located on the outside of the annular protrusion. The guide protrusion 26 is inserted into the guide groove 24, thereby forming a limiting effect on the back plate 14 in the axial direction of the annular protrusion, preventing the back plate 14 from separating from the annular protrusion along the axial direction of the annular protrusion, and enhancing the stability of the back plate 14.

[0042] Specifically, each of the two sides 36 is provided with a guide protrusion 26, and the opposite sides of the annular protrusion are provided with guide grooves 24 for the guide protrusion 26 to be inserted.

[0043] Preferably, the backplate body 34, the two sides 36 and the two guide protrusions 26 are integrally formed to ensure the overall strength of the backplate 14.

[0044] In this embodiment, the annular protrusion recesses into the inner wall of the guide groove 24 to form a first limiting portion 50, and the guide protrusion 26 is provided with a second limiting portion 52. The first limiting portion 50 is equipped with a limiting member 54, and a portion of the limiting member 54 is located outside the first limiting portion 50 to cooperate with the second limiting portion 52. When the back plate 14 is installed on the annular protrusion, the portion of the limiting member 54 located outside the first limiting portion 50 cooperates with the second limiting portion 52 to form a limiting effect, thereby enhancing the stability of the back plate 14.

[0045] The cooperation between the limiting member 54 and the second limiting part 52 can mean that the second limiting part 52 protrudes into the guide groove 24 and abuts against the part of the limiting member 54 located outside the first limiting part 50 to form a limiting effect, or that the second limiting part 52 is recessed into the surface of the guide protrusion 26 so that the part of the limiting member 54 located outside the first limiting part 50 can be housed in the second limiting part 52 to form a limiting effect.

[0046] In this embodiment, the limiting member 54 is a cylindrical limiting shaft, the axial direction of which is perpendicular to the extending direction of the guide groove 24. The first limiting part 50 is a first groove provided on the inner wall of the guide groove 24, and the second limiting part 50 is a second groove corresponding to the guide protrusion 26. When the back plate 14 is installed on the annular protrusion, the first groove and the second groove can cooperate to form a cylindrical limiting hole that is adapted to the limiting shaft. The limiting shaft is located in the limiting hole, that is, part of the limiting shaft is located in the first groove and part of it is located in the second groove, thereby forming a limiting effect in the sliding direction of the back plate 14. Specifically, the limiting shaft and the limiting hole are interference-fitted to enhance the limiting effect.

[0047] There are two limiting shafts. The inner wall of each guide groove 24 is provided with a first groove, and each first groove is equipped with a limiting shaft. The two guide protrusions 26 are respectively provided with a second groove. When the back plate 14 is installed on the annular protrusion, the two first grooves and the two second grooves cooperate to form two limiting holes. Each limiting hole contains a limiting shaft to enhance the limiting effect.

[0048] Please see Figures 6 to 9 In another embodiment, the accessory body 12 is an extension frame, which includes multiple frame strips 38 connected end to end in sequence. The multiple frame strips 38 enclose a fitting space 40 that matches the electronic product. The extension frame can be fitted onto the outside of the electronic product through the fitting space 40. It should be noted that the electronic product can be a mobile phone in a bare state or a mobile phone with a phone case.

[0049] One of the frame strips 38, near the camera of the electronic product, forms the mounting part 22 of the accessory body 12. The back plate 14 is slidably mounted on the frame strip 38 and near the camera of the electronic product. The shape of the slide groove 20 is adapted to the shape of the frame strip 38. By driving the back plate 14 to slide along the extension direction of the frame strip 38, the frame strip 38 can be inserted into or removed from the slide groove 20, thereby installing the back plate 14 on or removing it from the frame strip 38.

[0050] Specifically, the expansion frame is a square frame with four frame strips 38 connected end to end to form a ring. The mounting part 22 is located at one end of one frame strip 38 near the other adjacent frame strip 38, that is, the back plate 14 is mounted on one end of one frame strip 38 near the other adjacent frame strip 38.

[0051] The frame 38 is provided with a connection structure 41 for connecting external photography and videography auxiliary equipment. The connection structure 41 includes at least one of the following: a threaded hole, a cold shoe opening, a hook hole, and an Arri positioning hole. The threaded hole and the Arri positioning hole can be threaded into the photography and videography auxiliary equipment, the cold shoe opening can be snapped into the photography and videography auxiliary equipment, and the hook hole can be hooked into the photography and videography auxiliary equipment to further expand the shooting function.

[0052] Specifically, the connection structure 41 includes a threaded hole, a cold shoe opening, an Arri positioning hole, and a hook hole, and there are multiple threaded holes, cold shoe openings, Arri positioning holes, and hook holes, so that the expansion frame can be connected to different photography and videography auxiliary equipment such as handles, tripods, filters, etc.

[0053] In this embodiment, the accessory body 12 includes a connecting portion 42 and an extension portion 44 connected to the connecting portion 42. The connecting portion 42 is U-shaped, and a groove 20 is formed on the inner side of the connecting portion 42. The connecting portion 42 is slidably fitted onto the outer side of the frame strip 38 through the groove 20. The extension portion 44 extends from one side of the connecting portion 42 to the top of the fitting space 40 and corresponds to the position of the camera of the electronic product. The mounting opening 18 is provided through the extension portion 44. The U-shaped connecting portion 42 includes two side plates that are spaced apart and opposite to each other and a connecting plate connected between the two side plates. The groove 20 is located between the two side plates. The frame strip 38 can be inserted between the two side plates or withdrawn from between the two side plates. When the back plate 14 is installed on the frame strip 38, the two side plates are located on opposite sides of the frame strip 38, and the connecting plate is located on the side of the frame strip 38 away from the fitting space 40. The extension portion 44 extends from one of the side plates into the fitting space 40.

[0054] Specifically, the connecting part 42 and the extension part 44 are integrally formed to ensure the overall strength of the back plate 14.

[0055] In this embodiment, the inner side of the connecting part 42 is provided with a guide protrusion 26, and the outer side of the frame strip 38 is provided with a corresponding guide groove 24. When the connecting part 42 is sleeved on the outer side of the frame strip 38, the guide protrusion 26 can be slidably inserted into the guide groove 24 to form a limiting effect in the direction perpendicular to the extension direction of the slide groove 20, thereby enhancing the stability of the connecting part 42 on the frame strip 38.

[0056] Specifically, guide protrusions 26 are provided on opposite sides of the connecting part 42, and guide grooves 24 are provided on opposite sides of the frame strip 38 along the axial direction of the sleeve space 40. Each guide protrusion 26 can be slidably inserted into a corresponding guide groove 24.

[0057] In one embodiment, a locking structure is provided between the back plate 14 and the mounting part 22. The locking structure has a locked state and an unlocked state. The back plate 14 can slide relative to the mounting part 22 to switch the locking structure between the locked state and the unlocked state. When the back plate 14 is installed to the mounting part 22, the locking structure is in the locked state, keeping the back plate 14 and the accessory body 12 relatively fixed, enhancing the stability of the back plate 14 in the installed state. When the back plate 14 is removed from the mounting part 22, the locking structure is in the unlocked state, releasing the locking effect and facilitating the sliding of the back plate 14 relative to the mounting part 22.

[0058] Understandably, the specific way in which the locking structure forms a locking effect is not limited. For example, the locking effect can be formed by snapping the back plate 14 with the mounting part 22, or by the locking structure abutting against the outside of the back plate 14.

[0059] In this application, the locking structure includes an elastic positioning member 46 provided in the mounting part 22 and a corresponding positioning hole 48 provided in the back plate 14. In the locked state, the elastic positioning member 46 is inserted into the positioning hole 48, and in the unlocked state, the elastic positioning member 46 is located outside the positioning hole 48. The elastic positioning element 46 is elastic and deformable. During the sliding of the back plate 14 relative to the mounting part 22, the back plate 14 will squeeze the elastic positioning element 46, causing the elastic positioning element 46 to deform and prevent it from affecting the sliding of the back plate 14. When the back plate 14 slides to the point where the positioning hole 48 moves to the elastic positioning element 46, the pressure of the back plate 14 on the elastic positioning element 46 disappears, and the elastic positioning element 46 returns to its initial state under its own elastic force, so that the elastic positioning element 46 is inserted into the positioning hole 48, forming a locking effect and positioning the back plate 14 at this position to enhance the stability of the back plate 14 at this position. If an external force is continued to be applied to the back plate 14 so that it slides relative to the accessory body 12, the back plate 14 squeezes the elastic positioning element 46 to deform it and withdraw it from the positioning hole 48, thus releasing the locking effect.

[0060] Understandably, the locking structure may also be without the positioning hole 48. The elastic positioning member 46 is used to abut against the outside of the back plate 14. That is, when the back plate 14 is installed to the mounting part 22, the elastic positioning member 46 abuts against the back plate 14 on one side of its sliding direction, which can also play a certain limiting effect on the back plate 14.

[0061] In other embodiments, the elastic positioning element 46 is disposed on the back plate 14 and the positioning hole 48 is disposed on the accessory body 12, which can also achieve the effect of locking and unlocking.

[0062] The specific number of elastic positioning elements 46 and positioning holes 48 is not limited; there can be one or more. In this application, there are multiple elastic positioning elements 46 and positioning holes 48, and they correspond one-to-one. Multiple elastic positioning elements 46 and multiple positioning holes 48 are arranged at intervals. In the locked state, each elastic positioning element 46 is inserted into a corresponding positioning hole 48, which further enhances the stability of the back plate 14 when it is installed on the accessory body 12.

[0063] like Figure 4 and Figure 5 As shown, in the embodiment where the accessory body 12 is a protective shell, the elastic positioning member 46 is provided on the side of the annular protrusion near the back plate body 34, and the positioning hole 48 is provided on the side of the back plate body 34 near the annular protrusion.

[0064] Specifically, the annular protrusion has a mounting hole 56 on the side near the back plate body 34. The elastic positioning member 46 includes an elastic member 58 located in the mounting hole 56 and a ball 60 connected to the elastic member 58. The ball 60 protrudes at least partially from the mounting hole 56, that is, the ball 60 protrudes from the outer surface of the annular protrusion. The positioning hole 48 is located on the side of the back plate body 34 near the annular protrusion. During the sliding process of the back plate 14 relative to the annular protrusion, the back plate body 34 squeezes the ball 60 and compresses and deforms the elastic member 58, causing the ball 60 to retract into the mounting hole 56. When the ball 60 moves to the positioning hole 48, the ball 60 extends out of the mounting hole 56 under the action of the elastic member 58 and inserts into the positioning hole 48, forming a positioning effect.

[0065] In this embodiment, there are two elastic positioning elements 46 and two positioning holes 48. The two elastic positioning elements 46 and the two positioning holes 48 are arranged at intervals along the direction perpendicular to the sliding direction of the back plate 14. During the sliding process of the back plate 14, the two elastic positioning elements 46 are simultaneously inserted into the corresponding positioning holes 48.

[0066] like Figure 8 and Figure 9 As shown, in the embodiment where the accessory body 12 is an extension frame, the elastic positioning member 46 is provided on the side of the frame strip 38 away from the sleeve space 40, and the positioning hole 48 is correspondingly provided on the connecting part 42 of the back plate 14.

[0067] Specifically, the frame strip 38 has a mounting hole 56 on the side away from the sleeve space 40. The elastic positioning member 46 includes an elastic member 58 located in the mounting hole 56 and a ball 60 connected to the elastic member 58. The ball 60 protrudes at least partially from the mounting hole 56, that is, the ball 60 protrudes from the outer surface of the frame strip 38. The positioning hole 48 is correspondingly located on the inner side of the connecting part 42. During the sliding process of the back plate 14 relative to the frame strip 38, the connecting part 42 will squeeze the ball 60 and compress and deform the elastic member 58. The ball 60 retracts into the mounting hole 56. When the ball 60 moves to the positioning hole 48, the ball 60 extends out of the mounting hole 56 under the action of the elastic member 58 and inserts into the positioning hole 48 to form a positioning effect.

[0068] In this embodiment, there are two elastic positioning elements 46 and two positioning holes 48. The two elastic positioning elements 46 and the two positioning holes 48 slide along the length direction perpendicular to the frame strip 38, i.e. the sliding direction of the back plate 14. During the sliding process of the back plate 14, the two elastic positioning elements 46 are inserted into the corresponding positioning holes 48 one after another.

[0069] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
