[0033] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, the element can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0034] Please refer to Figures 1 to 3 , a photography - assisting device 10 provided by an embodiment of the present utility model includes a main body frame 12 and an adjusting member 14 connected to the main body frame 12. A receiving space 16 and a connecting structure 18 are provided on the main body frame 12. The receiving space 16 is used to accommodate an electronic device 20 with a shooting function, such as a mobile phone, a tablet, etc. In this application, it is taken as an example that the electronic device 20 is a mobile phone for illustration. The connecting structure 18 is used to externally connect a shooting accessory. The shooting accessory is a product for assisting shooting, such as a handle, a fill - light, a microphone, a filter, a bracket, etc. The shooting accessory can be indirectly installed on the mobile phone through the photography - assisting device 10 to assist the mobile phone in shooting.

[0035] The specific form of the connecting structure 18 is not limited and can be set according to the characteristics of the shooting accessory, such as a snap - fit structure, a magnetic - attraction structure, a connection interface, etc. In this embodiment, the connecting structure 18 includes an interface for connecting with the shooting accessory. The interface includes at least one of the following: a threaded port 22, a cold - shoe port 24 (i.e., a dovetail groove), and a hook port 26. The threaded port 22 can enable the shooting accessory to be in threaded cooperation with the main body frame 12, the cold - shoe port 24 can enable the shooting accessory to be in snap - fit cooperation with the main body frame 12, and the hook port 26 can enable the shooting accessory to be hung on the main body frame 12.

[0036] Specifically, the connecting structure 18 includes a threaded port 22, a cold - shoe port 24, and a hook port 26, and the number of the threaded port 22, the cold - shoe port 24, and the hook port 26 is multiple, so that the main body frame 12 can be connected to different shooting accessories.

[0037] In one embodiment, the adjusting member 14 is connected to the main body frame 12 and can move relative to the main body frame 12 to generate a displacement relative to the main body frame 12 in the first direction X and / or the second direction Y of the receiving space 16. The photographic auxiliary device 10 adjusts the size of the area in the receiving space 16 where the electronic device 20 can be placed in the first direction X and / or the second direction Y through the adjusting member 14, so that the size of the area in the receiving space 16 for accommodating the electronic device 20 changes, enabling the photographic auxiliary device 10 to accommodate both a mobile phone in a bare machine state and a mobile phone with a protective case, and the sizes of the protective cases can also be different, making the photographic auxiliary device 10 no longer limited to accommodating a mobile phone of a specific size, thereby broadening the usage scenarios of the photographic auxiliary device 10.

[0038] Preferably, when the adjusting member 14 moves relative to the main body frame 12, the adjusting member 14 generates a displacement relative to the main body frame 12 in the mutually perpendicular first direction X and second direction Y of the receiving space 16 to adapt to the situation where both the length and width of the electronic device 20 change, enhancing the stability of the electronic device 20 in the receiving space 16.

[0039] In this embodiment, the main body frame 12 is generally rectangular, and the first direction X and the second direction Y are the length direction and the width direction of the main body frame 12 respectively.

[0040] The adjusting member 14 moves relative to the main body frame 12 to generate a displacement relative to the main body frame 12 in the first direction X and the second direction Y, which may mean that the adjusting member 14 can move relative to the main body frame 12 in the first direction X and can also move relative to the main body frame 12 in the second direction Y. Or, it may also mean that the adjusting member 14 can move relative to the main body frame 12 in a direction inclined relative to the first direction X and the second direction Y, such as the diagonal direction of the main body frame 12, and can also generate a relative displacement in the first direction X and the second direction Y.

[0041] In one embodiment, the photographic auxiliary device 10 further includes a connecting component 28. The connecting component 28 connects the adjusting member 14 and the main body frame 12 to be relatively movable, that is, after the adjusting member 14 is connected to the main body frame 12 through the connecting component 28, it can move relative to the main body frame 12.

[0042] The specific type of the connecting component 28 is not limited as long as it can enable the adjusting member 14 to move relative to the main body frame 12. For example, the connecting component 28 has elasticity, so that the connecting component 28 can move the adjusting member 14 relative to the main body frame 12 through elastic deformation. Or, the connecting component 28 is movably installed on the main body frame 12, and the connecting component 28 moves relative to the main body frame 12 and drives the adjusting member 14 to move relative to the main body frame 12 together.

[0043] In one embodiment, the photography assistance device 10 further includes a limiting structure 30. The limiting structure 30 is disposed on the adjusting member 14 and / or the main body frame 12. The limiting structure 30 is used to limit the electronic device 20 in the axial direction of the receiving space 16. That is, the limiting structure 30 is used to limit the electronic device 20 in a direction perpendicular to the first direction X and the second direction Y, reducing the risk of the electronic device 20 falling out of the receiving space 16 of the main body frame 12 and enhancing the stability of the electronic device 20.

[0044] The limiting structure 30 may be a limiting groove 32 disposed on the adjusting member 14 and / or the main body frame 12. The limiting groove 32 communicates with the receiving space 16. When the mobile phone is located in the receiving space 16, a part of the edge area of the mobile phone is inserted into the limiting groove 32. Two opposite groove walls of the limiting groove 32 limit the mobile phone in the axial direction of the receiving space 16. Alternatively, the limiting structure 30 may also be a limiting protrusion 34 disposed on the adjusting member 14 and / or the main body frame 12. The limiting protrusion 34 extends into the receiving space 16. When the mobile phone is located in the receiving space 16, the limiting protrusion 34 abuts against the side surface of the mobile phone in the axial direction of the receiving space 16, thereby achieving the limiting effect.

[0045] As Figure 2 and Figure 3 As shown, in the first embodiment, the number of the adjusting members 14 is at least two. At least two adjusting members 14 are respectively disposed on different sides of the main body frame 12. At least one adjusting member 14 generates a displacement in the first direction X, and at least one adjusting member 14 generates a position change in the second direction Y. That is, at least one adjusting member 14 is disposed on one side of the main body frame 12 in the first direction X. This adjusting member 14 can move relative to the main body frame 12 in the first direction X, thereby generating a displacement relative to the main body frame 12 in the first direction X. At least one adjusting member 14 is disposed on one side of the main body frame 12 in the second direction Y. This adjusting member 14 can move relative to the main body frame 12 in the second direction Y, thereby generating a displacement relative to the main body frame 12 in the second direction Y. In this embodiment, by respectively disposing the adjusting members 14 on different sides of the main body frame 12, the adjusting members 14 on different sides adjust the size of the area for placing the mobile phone in different directions to accommodate mobile phones of corresponding sizes.

[0046] The connecting component 28 includes a knob 36 movably disposed on the main body frame 12. A through hole 37 is provided on the main body frame 12. One end of the knob 36 is located on the side of the main body frame 12 away from the receiving space 16 for the user to rotate and operate, and the other end is movably inserted through the main body frame 12 through the through hole 37 and is in threaded cooperation with the adjusting member 14. The adjusting member 14 cannot rotate relative to the main body frame 12. Therefore, when the knob 36 rotates relative to the main body frame 12, it cannot drive the adjusting member 14 to rotate together. However, since the adjusting member 14 is in threaded cooperation with the knob 36, the adjusting member 14 can perform a linear motion relative to the main body frame 12 along the first direction X or the second direction Y under the drive of the knob 36, thereby adjusting the position of the adjusting member 14 in the receiving space 16, so that the adjusting member 14 can abut against the mobile phone under the drive of the knob 36 and tightly press the mobile phone against the main body frame 12, keeping the mobile phone and the main body frame 12 relatively fixed and preventing the mobile phone from falling out of the receiving space 16, thus realizing the installation of the mobile phone in the main body frame 12.

[0047] In this embodiment, the main body frame 12 is annular and includes two frame bars spaced opposite to each other in the first direction X and two frame bars spaced opposite to each other in the second direction Y. One frame bar in the first direction X and one frame bar in the second direction Y are respectively provided with the adjusting member 14 and the knob 36. The adjusting member 14 in the first direction X is used to abut against one side of the mobile phone in the first direction X, and the adjusting member 14 in the second direction Y is used to abut against one side of the mobile phone in the second direction Y, so as to tightly press the mobile phone against the main body frame 12 in two mutually perpendicular directions.

[0048] The main body frame 12 is provided with a receiving groove 38 and a guiding post 40 located in the receiving groove 38. The receiving groove 38 is communicated with the receiving space 16 and the through hole 37. The adjusting member 14 is movably received in the receiving groove 38, and the shape of the adjusting member 14 is adapted to the shape of the receiving groove 38. The adjusting member 14 is provided with a guiding hole 42, and the guiding post 40 is movably inserted into the guiding hole 42. The axial direction of the guiding post 40 is consistent with the axial direction of the knob 36. One end of the knob 36 passes through the through hole 37 and extends into the receiving groove 38 to be in threaded cooperation with the adjusting member 14. When the knob 36 rotates, since the adjusting member 14 cannot rotate in the receiving groove 38, the rotational output of the knob 36 is converted into a linear output, and the adjusting member 14 performs a linear motion along the axial direction of the guiding post 40, so as to move towards the receiving space 16 or move away from the receiving space 16 to adjust the relative position of the adjusting member 14. During the movement of the adjusting member 14, the cooperation between the guiding post 40 and the guiding hole 42 can play a guiding role and can also prevent the adjusting member 14 from falling out of the receiving groove 38.

[0049] The specific number of the guide posts 40 and the guide holes 42 is not limited, and it can be one or multiple. Specifically, the number of both the guide posts 40 and the guide holes 42 is two and they correspond to each other one by one, and each positioning post is inserted into a corresponding positioning hole.

[0050] In this embodiment, limiting structures 30 are provided on both the main body frame 12 and the adjusting member 14. The limiting structures 30 are limiting protrusions 34 extending into the receiving space 16. The limiting protrusion 34 on the adjusting member 14 is located on one axial side of the receiving space 16, and the limiting protrusion 34 on the main body frame 12 is located on the other axial side of the receiving space 16. When the mobile phone is located in the receiving space 16, along the axis of the receiving space 16, the mobile phone is located between the limiting protrusion 34 of the adjusting member 14 and the limiting protrusion 34 of the main body frame 12.

[0051] As Figure 4 and Figure 5 shown, in the second embodiment, the main body frame 12 is a square frame, and at least one corner of the main body frame 12 is provided with a notch 44. The adjusting member 14 is disposed in the notch 44 or can move into the notch 44 through the connecting assembly 28. The corner is located at the connection of different sides of the main body frame 12, and the corner of the main body frame 12 corresponds to the corner position of the mobile phone, so that one adjusting member 14 can simultaneously abut against two adjacent sides of the mobile phone to form a fixing effect on the mobile phone.

[0052] In this embodiment, a notch 44 is provided at one corner of the main body frame 12. The connecting assembly 28 includes a first mounting shaft 46 disposed on the main body frame 12, a second mounting shaft 48 disposed on the adjusting member 14, and an annular sleeve 50. Two ends of the annular sleeve 50 are respectively sleeved on the first mounting shaft 46 and the second mounting shaft 48. The annular sleeve 50 has a certain elasticity, such as a rubber band. When the adjusting member 14 is subjected to an external force, the annular sleeve 50 can be deformed, so that the adjusting member 14 moves relative to the main body frame 12, adjusts the position of the adjusting member 14, and further adjusts the size of the area of the receiving space 16 for placing the mobile phone.

[0053] In this embodiment, the shape of the notch 44 is adapted to the shape of the adjusting member 14, and both are L-shaped. Two ends of the adjusting member 14 are respectively connected to the main body frame 12 through the annular sleeve 50. One annular sleeve 50 is used for the adjusting member 14 to move relative to the main body frame 12 in the first direction X, and the other annular sleeve 50 is used for the adjusting member 14 to move relative to the main body frame 12 in the second direction Y. Finally, the adjusting member 14 can move relative to the main body frame 12 in both the first direction X and the second direction Y.

[0054] On the main body frame 12, first grooves 52 are respectively provided on opposite sides of the notch 44. At the end portions of the adjusting member 14 close to the first grooves 52, second grooves 54 are respectively provided correspondingly. The first mounting shaft 46 is located in the first groove 52, the second mounting shaft 48 is located in the second groove 54, and the annular socket member 50 is located in the communicating space formed by the cooperation of the first groove 52 and the second groove 54, so as to improve the compactness of the overall structure.

[0055] In this embodiment, at two corners on a diagonal line of the main body frame 12, one is provided with a notch 44 and the other is provided with a limiting structure 30. The adjusting member 14 is also provided with a limiting structure 30. The limiting structure 30 is a limiting groove 32 communicated with the receiving space 16. When the mobile phone is located in the receiving space 16, two corner portions on a diagonal line of the mobile phone are respectively located in the two limiting grooves 32, so as to form a limiting effect on the mobile phone and prevent the mobile phone from falling out of the receiving space 16.

[0056] As Figure 6 shown, in the third embodiment, notches 44 are respectively provided at two corners on a diagonal line of the main body frame 12, that is, two notches 44 are provided on the main body frame 12. The connecting assembly 28 includes a supporting portion 56 fixedly connected to the main body frame 12 and two elastic connecting members 58 extending outward from the supporting portion 56. The adjusting member 14 is connected to one end of the elastic connecting member 58 far from the supporting portion 56. When the elastic connecting member 58 deforms telescopically relative to the supporting portion 56, the adjusting member 14 can move relative to the main body frame 12 to adjust the relative position of the adjusting member 14, so that the two adjusting members 14 are respectively located in the two notches 44 to be connected to two corner portions of the mobile phone on a diagonal line, thereby fixing the mobile phone in the main body frame 12.

[0057] The specific type of the elastic connecting member 58 is not limited, such as a spring, a rubber cord, etc.

[0058] The supporting portion 56 is connected to opposite sides of the main body frame 12 and is located at the middle position of the main body frame 12. The two elastic connecting members 58 can respectively deform along the diagonal line of the main body frame 12 towards the corresponding notches 44, so that the adjusting member 14 moves relative to the notches 44.

[0059] Specifically, the main body frame 12 includes two L-shaped frames. The two frames are arranged at intervals and form two notches 44 distributed along the diagonal line. Both ends of the supporting portion 56 are fixedly connected to the two frames respectively.

[0060] In this embodiment, the adjusting member 14 is provided with an avoidance opening 60 for matching the angle of the electronic device 20. When the electronic device 20 is located in the receiving space 16, the angle of the electronic device 20 can pass through the corresponding avoidance opening 60, so that the adjusting member 14 forms an effect of sleeving on the corner portion of the electronic device 20 through the avoidance opening 60, reducing the risk of separation between the adjusting member 14 and the electronic device 20.

[0061] As Figure 7 shown, in the fourth embodiment, the main difference between the photographic auxiliary device 10 and the photographic auxiliary device 10 in the third embodiment is that a magnetic attraction member 62 is provided on the support portion 56 in this embodiment. The magnetic attraction member 62 is used for magnetic attraction cooperation with the electronic device 20, so that the electronic device 20 is magnetically fixed on the support portion 56, enhancing the stability of the electronic device 20.

[0062] The specific number of the magnetic attraction members 62 is not limited. When the number is small, magnetic attraction members 62 with relatively large volume can be selected. When the number is large, magnetic attraction members 62 with relatively small volume can be selected, as long as sufficient magnetic attraction can be generated.

[0063] It can be understood that in the third embodiment, the mobile phone is supported by the support portion 56 in the axial direction of the accommodation space 16, which can play a certain limiting effect. In the fourth embodiment, the mobile phone is supported by the support portion 56 in the axial direction of the accommodation space 16, and at the same time, there is the magnetic attraction effect of the magnetic attraction member 62. Therefore, the limiting structure 30 can be provided on the main body frame 12, or the limiting structure 30 can be not provided.

[0064] The above embodiments are only the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
