Description

Technical Field

[0001] This utility model relates to the field of mobile terminal photography accessories technology, and in particular to a mobile terminal photography auxiliary tool and mobile terminal kit. Background Technology

[0002] Selfie sticks are mobile photography aids that effectively expand shooting angles and provide users with a more convenient shooting experience. During use, users can attach their mobile devices with camera functions to the selfie stick and extend the telescopic rod to expand the shooting range, thus achieving better shooting results. Currently, most traditional selfie sticks use a clamping part to secure the mobile device. To prevent interference between the telescopic rod and the mobile device when rotating, the rotating mechanism is usually located outside the clamping part. This means that the selfie stick cannot be fully retracted into the back of the mobile device when stored, and it still occupies a considerable amount of space, making it inconvenient to carry. Utility Model Content

[0003] This utility model provides a mobile terminal photography auxiliary tool and a mobile terminal kit, aiming to solve the problem that the mobile terminal photography auxiliary tool cannot be completely folded into the back of the mobile terminal, thus occupying a large space.

[0004] The mobile terminal photography auxiliary tool provided by this utility model includes a connecting structure, a rotating mechanism, and a rod assembly. The connecting structure has a fixing surface for fitting with the mobile terminal and a storage surface facing away from the fixing surface. The storage surface has a connecting part.

[0008] In one embodiment, the first locking structure includes a retractable telescopic member and a limiting hole for insertion of the telescopic member; the telescopic member is disposed on the first connecting member, and the limiting hole is disposed on the bottom wall or side wall of the slide groove. The limiting hole includes a first limiting hole and a second limiting hole, with the first limiting hole located at the first end and the second limiting hole located at the second end. When the telescopic member is inserted into the first limiting hole or the second limiting hole, the first rod is locked in a retracted position or an extended position. Alternatively, the limiting hole is disposed on the first connecting member, and the telescopic member is disposed on the bottom wall or side wall of the slide groove. The telescopic member includes a first telescopic member and a second telescopic member, with the first telescopic member located at the first end and the second telescopic member located at the second end. When the first telescopic member or the second telescopic member is inserted into the limiting hole, the first rod is locked in a retracted position or an extended position.

[0009] In one embodiment, adjacent rods each have a first end facing the connecting structure and a second end away from the connecting structure. The second connector is fixedly connected to the second end of the preceding rod, and the following rod has a groove that mates with the second connector, with the second connector slidably disposed within the groove. Alternatively, the second connector is fixedly connected to the first end of the following rod, the preceding rod has a groove that mates with the second connector, and the second connector slidably disposed within the groove. Alternatively, both the preceding and following rods have grooves that mate with the second connector, with the second connector partially slidably disposed within the groove of the preceding rod and partially slidably disposed within the groove of the following rod.

[0010] In one embodiment, the second locking structure includes a retractable telescopic member and a limiting hole for insertion of the telescopic member; the telescopic member is disposed on the second connecting member, and the limiting hole is disposed on the bottom wall or side wall of the slide groove. The limiting hole includes a first limiting hole and a second limiting hole, with the first limiting hole located at the first end and the second limiting hole located at the second end. When the telescopic member is inserted into the first limiting hole or the second limiting hole, the corresponding rod is locked in a retracted position or an extended position.

[0011] In one embodiment, the connection structure is a patch, which is provided with a magnetic adsorption element and is adsorbed onto the back of the mobile terminal by the magnetic adsorption element; or, the patch is a magnetic patch; or, the patch is provided with a vacuum suction cup and is adsorbed onto the back of the mobile terminal by the vacuum suction cup; or, the patch is adhered to the back of the mobile terminal by an adhesive layer.

[0012] In one embodiment, the third joint has a clearance groove on the side facing the connecting structure.

[0014] This utility model relates to a mobile terminal photography aid by connecting a rotating mechanism to the storage surface of a connecting structure. The rotating mechanism is positioned within the range of the connecting structure, while the rod assembly, in its stored state, retracts side-by-side along its width and rests against the storage surface. This allows the rotating mechanism and rod assembly to rest against the back of the mobile terminal in the stored state, solving the problem of traditional selfie sticks occupying a large amount of space when stored. Furthermore, the rotating mechanism uses multi-stage joints to address interference with the mobile terminal. Specifically, the end of the first joint furthest from the first pivot can rotate from within the storage surface to outside its range, and the end of the second joint furthest from the second pivot can rotate from within the range of the first joint to outside its range. Through these two stages of rotation, the second joint can further move away from the mobile terminal, thereby moving the third joint to the side of the mobile terminal, ensuring that the third joint does not interfere with the mobile terminal when rotating towards the front. In short, this utility model solves the problem of large storage space in traditional selfie sticks while maintaining flexibility in adjusting the shooting angle. In addition, the stick component in this mobile terminal photography aid not only functions as a selfie stick, but also acts as a stand when folded up, integrating multiple functions into one and improving its usability.

Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0035] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0036] This utility model proposes a mobile terminal photography assistance tool, which is used in conjunction with a mobile terminal with a camera function. The mobile terminal can be, but is not limited to, a mobile phone, a tablet computer, or a point-and-shoot camera. The following description uses a mobile phone as an example. The directions "up," "down," "front," "back," "left," and "right" mentioned in the text are defined based on the normal usage state of the mobile phone. When the user holds the mobile phone vertically facing the screen, the top and bottom directions of the screen are the up and down directions, the left and right directions of the screen are the left and right directions, the side of the screen facing the user is the "front" and "front face," and the side facing away from the user is the "back" and "back face."

[0037] like Figures 1 to 8 As shown, the mobile terminal photography auxiliary tool provided by this utility model includes a connecting structure 10, a rotating mechanism 20, and a rod assembly 30. The connecting structure 10 has a fixing surface for fitting with the mobile terminal and a storage surface facing away from the fixing surface. The storage surface is provided with a connecting part 11. The rotating mechanism 20 includes a first joint 21, a second joint 23, and a third joint 25. The first joint 21 is rotatably connected to the connecting part 11 via a first rotating shaft 22. The second joint 23 is rotatably connected to the first joint 21 via a second rotating shaft 24. The third joint 25 is rotatably connected to the second joint 25 via a third rotating shaft 26. 23. The first joint 21 can be moved from the storage surface to outside the storage surface, and the second joint 23 can be moved from the range of the first joint 21 to outside the range of the first joint 21, so that the third joint 25 can be moved to the side of the mobile terminal 200. The rod assembly 30 includes a first rod 31 and a plurality of sub-rods 32 connected in sequence. The first rod 31 is connected to the third joint 25, wherein one sub-rod 32 is connected to the first rod 31. Each sub-rod 32 has an unfolded state that slides along the length direction and a stored state that is folded together in the width direction and at least partially abuts the back of the mobile terminal 200.

[0038] Traditional selfie sticks typically place the rotating mechanism outside the connecting structure, preventing it from fully retracting into the back of the mobile device and thus occupying significant space. In contrast, this mobile device photography aid places the rotating mechanism 20 on the side of the connecting structure opposite to the mobile device 200. Specifically, the connecting structure 10 has a fixing surface for contacting the mobile device 200 and a storage surface facing away from the fixing surface. The storage surface has a connecting part 11 for connecting the rotating mechanism. The connecting part 11 is located near the edge of the storage surface. When the fixing surface is in contact with the back of the mobile device 200, the connecting part 11 can be located near the left, right, top, or bottom edge of the mobile device 200. The rotating mechanism 20 can rotate, allowing users to adjust the shooting angle of the mobile device 200, enabling horizontal and vertical front-facing and rear-facing shooting. To facilitate the rotation of the rod assembly 30 to the front of the mobile terminal for front-facing shooting, the rotating mechanism 20 provided in this embodiment includes a first joint 21, a second joint 23, and a third joint 25. The first joint 21 is rotatably connected to the adapter 11 via a first rotating shaft 22. The second joint 23 is rotatably connected to the end of the first joint 21 away from the adapter 11 via a second rotating shaft 24. The first rotating shaft 22 and the second rotating shaft 24 are parallel to the storage surface and are parallel to each other. The third joint 25 is rotatably connected to the end of the second joint 23 away from the first joint 21 via a third rotating shaft 26, and the third rotating shaft 26 is perpendicular to the second rotating shaft 24. For example, the axes of the first rotating shaft 22 and the second rotating shaft 24 can be the vertical direction of the mobile terminal 200, and the axis of the third rotating shaft 26 can be the horizontal direction of the mobile terminal 200. Thus, the rotation direction of the first joint 21 and the second joint 23 is the horizontal direction of the mobile terminal 200, and the rotation direction of the third joint 25 is the front-back direction of the mobile terminal 200. The end of the first joint 21 that is away from the first pivot 22 can rotate from the area of ​​the storage surface to the outside of the storage surface. The end of the second joint 23 that is away from the second pivot 24 can rotate from the area of ​​the first joint 21 to the outside of the first joint 21. After two stages of rotation, the end of the second joint 23 that is away from the second pivot 24 can rotate from the area of ​​the mobile terminal 200 to the outside of the mobile terminal 200. This avoids interference between the third joint 25 and the mobile terminal 200 when the third joint 25 rotates to the side of the mobile terminal. It also allows the end of the third joint 25 that is away from the third pivot 26 to rotate from the back of the mobile terminal 200 to the front of the mobile terminal 200, thus enabling front-facing shooting.

[0039] The pole assembly 30 is used to widen the shooting angle. Specifically, the pole assembly 30 includes a first pole 31 connected to the third joint 25 and several sub-pole bodies 32 connected in sequence. One edge of the sub-pole body 32 is connected to the first pole 31. The first pole 31 and the several sub-pole bodies 32 are in an extended state, that is, each sub-pole body 32 extends along the length direction of the first pole 31 to act as a selfie stick. When the user does not need to use the selfie stick function, the first pole 31 and the several sub-pole bodies 32 can be retracted from the extended state to a retracted state in which they are parallel in the width direction. Each sub-pole body 32 has the same length as the first pole 31, so that when each pole is in the retracted state, the upper and lower edges of each pole are flush. When the pole assembly 30 is in the retracted state, the pole assembly 30 is plate-shaped. The rotating mechanism 20 rotates to a suitable angle and supports the pole assembly 30 on a plane to serve as a mobile phone holder.

[0040] In summary, this utility model's mobile terminal photography auxiliary tool connects the rotating mechanism 20 to the storage surface of the connecting structure 10, i.e., the rotating mechanism 20 is placed within the range of the connecting structure. Simultaneously, the rod assembly 30, in the stored state, is folded together along its width and abuts against the storage surface. This allows the rotating mechanism 20 and the rod assembly 30 to rest against the back of the mobile terminal 200 in the stored state, solving the problem of the transmission selfie stick occupying a large amount of space in the stored state. Furthermore, the rotating mechanism 20 uses multi-stage joints to resolve interference with the mobile terminal 200. Specifically, the end of the first joint 21 furthest from the first rotating axis 22 can rotate from the storage surface to outside the storage surface, and the end of the second joint 23 furthest from the second rotating axis 24 can rotate from the first joint 21 to outside the first joint 21. Through these two stages of rotation, the second joint 23 can further move away from the mobile terminal 200, thereby moving the third joint 25 to the side of the mobile terminal, ensuring that the third joint does not interfere with the mobile terminal 200 when rotating towards the front of the mobile terminal 200. In short, this utility model's technical solution can solve the problem of large storage space in traditional selfie sticks while ensuring flexibility in adjusting the shooting angle. Furthermore, the stick component 30 in this mobile terminal photography aid not only functions as a selfie stick but also acts as a support when folded, integrating multiple functions and improving usability.

[0041] The connecting structure 20 can be a patch, which may have a magnetic adsorption component. The patch is magnetically attached to the back of the mobile terminal 200. Alternatively, the patch itself may be a magnetic patch, adsorbing to the back of the mobile terminal 200 by its own magnetism. Alternatively, the patch may have a vacuum suction cup, adsorbing to the back of the mobile terminal 200 by the vacuum suction cup. Alternatively, the patch may be adhered to the back of the mobile terminal 200 by an adhesive layer. In this case, the side of the patch that is in contact with the mobile terminal 200 is the fixing surface, and the side of the patch that is opposite to the mobile terminal 200 is the storage surface. The adapter 11 protrudes from the storage surface of the patch and is integrally formed with the patch.

[0042] Or, refer to Figure 11 The connecting structure 10 may include a back plate 13 and a clamping part 14 disposed on the back plate 13. The clamping part 14 is disposed on the side of the back plate 13 facing the mobile terminal, and a receiving cavity for accommodating the mobile terminal is formed between the clamping part 14 and the back plate 13. In this case, the side of the back plate 13 that is in contact with the mobile terminal 200 is the fixing surface, and the side of the back plate 13 that is opposite to the mobile terminal 200 is the receiving surface. The adapter part 11 protrudes from the receiving surface of the back plate 13 and is integrally disposed with the back plate 13. Specifically, the clamping part 14 may be two opposing clamps, in which case a receiving cavity for accommodating the mobile terminal is formed between the two clamps and the back plate 13; or, the clamping part 14 may be clamps disposed on the four sides of the back plate 13, in which case a receiving cavity for accommodating the mobile terminal is formed between the four clamps and the back plate 13; or, the clamping part 14 may be a rolled edge disposed around the four edges of the back plate 13, in which case the back plate 13 and the rolled edge together form a mobile phone case.

[0043] Figure 1 The diagram shows the mobile terminal photography aid attached to the back of the phone and in a stowed state. At this time, the first joint 21, the second joint 23 and the third joint 25 remain in their initial state, that is, they do not rotate. The rod assembly 30 is stowed in the back of the phone for easy carrying.

[0044] Figure 2 The diagram shows the mobile terminal photography aid attached to the back of a mobile phone and acting as a horizontal support. At this time, the rod assembly 30 is in a retracted state, the first joint 21 does not rotate, the second joint 23 drives the third joint 25 to rotate to a suitable angle, the rod assembly 30 is plate-shaped and forms a certain angle with the back of the mobile phone, and the outermost rod contacts and abuts against the supporting plane to act as a horizontal mobile phone support.

[0045] Figure 3The diagram shows the mobile terminal photography aid attached to the back of a mobile phone and acting as a vertical stand. At this time, the rod assembly 30 is in a retracted state, the first joint 21 and the second joint 23 do not rotate, the third joint 25 rotates backward around the third pivot 26, and the rod assembly 30 as a whole is plate-shaped and forms a certain angle with the back of the mobile phone. The bottom edge of each rod contacts and abuts against the supporting plane, thus serving as a vertical mobile phone stand.

[0046] Figure 4 This diagram illustrates the mobile terminal photography aid when attached to the back of a phone and used for rear-facing portrait photography. Figure 5 This diagram illustrates the mobile terminal photography aid attached to the back of a mobile phone and used for rear-facing landscape photography. In this state, the first rod 31 and each sub-rod 32 are extended. Since the first rod 31 is connected to the third joint 25, the third joint 25 rotates rearward around the third pivot 26, allowing the extended rod assembly 30 to be rotated to the desired angle, thus enabling rear-facing long-distance selfies.

[0047] Figure 6 This diagram illustrates the mobile terminal photography aid when attached to the back of the phone and used for front-facing portrait photography. Figure 7 This diagram illustrates the mobile terminal photography aid attached to the back of a mobile phone and used for front-facing landscape photography. In this state, the first rod 31 and each sub-rod 32 are extended. The first joint 21 rotates 180° relative to the connecting part 11, moving from the storage area to outside the storage area. The second joint 23 rotates 180° relative to the first joint 21, moving from the area of ​​the first joint 21 to outside the area of ​​the first joint 21. After two rotations, the third joint 25 can move from within the phone's range to outside the phone's range, facilitating forward rotation of the third joint 25. Since the first rod 31 is connected to the third joint 25, the third joint 25 rotates forward around the third pivot 26, allowing the extended rod assembly 30 to be rotated to the desired angle, enabling front-facing long-distance selfies.

[0048] Among them, the first rotating shaft 22, the second rotating shaft 24, and the third rotating shaft 26 are all damping rotating shafts. During the shooting process, whether shooting with the front or rear camera, the mobile terminal 200 needs to be kept at a specific angle to obtain the ideal shooting effect. The damping rotating shaft can provide a certain resistance, so that each joint can be stably kept in the position after rotating to the required angle, and will not easily change the angle due to slight external forces (such as gravity, hand tremors, wind, etc.).

[0049] To avoid rotational interference between the third joint 25 and the second joint 23, refer to... Figure 8The second joint 23 includes a first connecting part 231 and a second connecting part 232. The first connecting part 231 is rotatably connected to the adapter part 11 via a second rotating shaft 24. The second connecting part 232 protrudes from the end of the first connecting part 231 facing the third joint 25. The end of the third joint 25 facing the second joint 23 is provided with a connecting groove 252 for the second connecting part 232 to be inserted. The second connecting part 232 is inserted into the connecting groove 252. The third rotating shaft 26 passes through the second connecting part 232 to connect the second connecting part 232 and the third joint 25.

[0050] The last sub-rod 32, which is the sub-rod 32 furthest from the first rod 31 in the retracted state, is equipped with a control module. The control module includes a wireless connection module and control buttons. The wireless connection module can be a Bluetooth module or a WIFI module, used for communication with the mobile terminal 200. The control buttons are located on the surface of the sub-rod 32 and are electrically connected to the wireless connection module. When the control button is pressed, the wireless connection module sends a shutter release command to the mobile terminal 200, thereby enabling long-distance photography.

[0051] Regarding the connection method of the rod assembly 30, please refer to... Figure 12 and Figure 13 In the embodiments provided by this utility model, the first rod 31 is slidably connected to the third joint 25 through the first connector 33, and a first locking structure is provided between the first connector 33 and the third joint 25 and / or the first rod 31. The first locking structure is used to maintain the first rod 31 in a retracted state or an extended state.

[0052] Similarly, the first rod 31 and the sub-rod 32, as well as the two adjacent sub-rods 32, are slidably connected by the second connector 34. The second connector 34 is provided with a second locking structure between itself and the adjacent rods. The second locking structure is used to keep the two adjacent rods in a retracted or unfolded state.

[0053] In its initial retracted state, the first rod 31 and the third joint 25 are tightly fitted together, with a large overlap area between them. Simultaneously, each sub-rod 32 overlaps side-by-side with the first rod 31, resulting in a compact plate-like structure for the entire rod assembly 30. At this point, the first rod 31 and each sub-rod 32 are locked in their retracted positions. When the user applies an outward pulling force to the rod assembly 30, the first rod 31 slides outward along the length of the third joint 25. During this sliding process, the overlap area between the first rod 31 and the third joint 25 gradually decreases, and the first rod 31 gradually extends outward, increasing the length of the rod assembly 30. When the first rod 31 slides to a designated position, the first locking structure engages with either the first rod 31 or the third joint 25 to lock the first rod 31 in its current extended position, maintaining its extended state. Similarly, each subsequent rod slides outward along the length of the preceding rod, gradually reducing the overlap between them, and the subsequent rods are pulled out sequentially. When the subsequent rod slides out to the designated position relative to the preceding rod, the second locking structure engages with the preceding or subsequent rod to lock the two adjacent rods in their current positions, maintaining their extended state. During this process, the overall length of the rod assembly 30 increases progressively. When the rod assembly 30 needs to be retracted, the user applies an inward pushing force to it. The first and second locking structures unlock under this force, and the rods slide in opposite directions. The overlap between adjacent rods and between the first rod 31 and the third joint 25 gradually increases, and the rods are retracted sequentially. Finally, the first and second locking structures lock the first rod 31 and each sub-rod 32 back into their retracted positions, ensuring that the rod assembly 30 remains stable and compact in its retracted state.

[0054] Regarding the connection method of the first connector 33, the third joint 25 and the first rod 31 respectively have a first end facing the connecting structure 10 and a second end away from the connecting structure 10. The first connector 33 can be fixedly connected to the second end of the third joint 25. The first rod 31 is provided with a groove 35 that cooperates with the first connector 33. The first connector 33 is slidably disposed in the groove 35.

[0055] Alternatively, the first connector 33 can be fixedly connected to the first end of the first rod 31, and the third joint 25 is provided with a groove 35 that cooperates with the first connector 33, and the first connector 33 is slidably disposed in the groove 35.

[0056] Alternatively, the third joint 25 and the first rod 31 are respectively provided with a groove 35 that cooperates with the first connector 33. The first connector 33 is partially slidably disposed in the groove 35 of the third joint 25 and partially slidably disposed in the groove 35 of the first rod 31.

[0057] The first locking structure is disposed between the first connecting member 33 and the corresponding sliding groove 35, thereby maintaining the first rod 31 in a retracted or extended state. The first locking structure may include a telescopic member and a limiting hole for inserting the telescopic member. The telescopic member is disposed on the first connecting member 33, and the limiting hole is disposed on the bottom wall or side wall of the sliding groove 35. The limiting hole includes a first limiting hole and a second limiting hole. The first limiting hole is located at the first end, and the second limiting hole is located at the second end. When the telescopic member is inserted into the first limiting hole or the second limiting hole, the first rod 31 is locked in the retracted or extended position.

[0058] When the first connecting member 33 is fixedly connected to the second end of the third joint 25, the first rod 31 is provided with a groove 35 that mates with the first connecting member 33. The first connecting member 33 is slidably disposed within the groove 35, and the first rod 31 can slide relative to the first connecting member 33. The end of the first connecting member 33 facing the first rod 31 is provided with a retractable telescopic member, such as a spring pin. The bottom wall or side wall of the groove 35 of the first rod 31 is provided with a first limiting hole and a second limiting hole for the insertion of the telescopic member. The first limiting hole is located at the first end of the first rod 31, and the second limiting hole is located at the second end of the first rod 31. When the first rod 31 slides relative to the third joint 25 to the set unfolded position, that is, when the first connecting member 33 abuts against the top wall of the groove 35, the telescopic member aligns with the first limiting hole, extends out, and inserts into the first limiting hole, thereby locking the first rod 31 in the unfolded position. When the user applies an inward pushing force to the first rod 31, the telescopic member is pulled out from the first limiting hole, thereby unlocking the first rod 31. When the first rod 31 slides relative to the third joint 25 to the set storage position, that is, when the first connecting member 33 abuts against the bottom wall of the slide groove 35, the telescopic member is aligned with the second limiting hole, extends out and inserts into the second limiting hole, thereby locking the first rod 31 in the storage position. When the user applies an outward pulling force to the first rod 31, the telescopic member is pulled out from the second limiting hole, thereby unlocking the first rod 31.

[0059] Of course, the positions of the limiting hole and the telescopic component can be interchanged; that is, the limiting hole is located on the first connecting member 33, and the telescopic component is located on the bottom wall or side wall of the slide groove 35. In this case, the telescopic component includes a first telescopic component and a second telescopic component. The first telescopic component is located at the first end, and the second telescopic component is located at the second end. When either the first or second telescopic component is inserted into the limiting hole, the first rod 31 is locked in the retracted or extended position. At this time, when the first rod 31 slides relative to the third joint 25 to the set extended position, that is, when the first connecting member 33 abuts against the top wall of the slide groove 35, the first telescopic component is opposite to the first limiting hole, extends out and inserts into the first limiting hole, thereby locking the first rod 31 in the extended position. When the user applies an inward pushing force to the first rod 31, the first telescopic component is pulled out from the first limiting hole, thereby releasing the lock on the first rod 31. When the first rod 31 slides relative to the third joint 25 to the set storage position, that is, when the first connecting member 33 abuts against the bottom wall of the slide groove 35, the second telescopic member aligns with the first limiting hole, extends out and inserts into the first limiting hole, thereby locking the first rod 31 in the storage position. When the user applies an outward pulling force to the first rod 31, the second telescopic member is pulled out from the first limiting hole, thereby unlocking the first rod 31.

[0060] In short, the unlocking and locking methods of the first locking structure are similar to those of an umbrella handle. Based on the above, when the first connector 33 is fixedly connected to the first end of the first rod 31, or when the first connector 33 is partially slidably disposed in the groove 35 of the third joint 25 and partially slidably disposed in the groove 35 of the first rod 31, the unlocking and locking process of the first locking structure is easy to deduce and will not be repeated here.

[0061] Regarding the connection method of the second connector 34, the front and rear adjacent rods respectively have a first end facing the connecting structure 10 and a second end away from the connecting structure 10. The second connector 34 can be fixedly connected to the second end of the front rod. The rear rod is provided with a sliding groove 35 that cooperates with the second connector 34. The second connector 34 is slidably disposed in the sliding groove 35.

[0062] Alternatively, the second connector 34 can be fixedly connected to the first end of the rear rod, and the front rod is provided with a groove 35 that cooperates with the second connector 34, and the second connector 34 is slidably disposed in the groove 35.

[0063] Alternatively, the front rod and the rear rod are each provided with a groove 35 that mates with the second connector 34. The second connector 34 is partially slidably disposed in the groove 35 of the front rod and partially slidably disposed in the groove 35 of the rear rod.

[0064] The second locking structure is disposed between the second connector 34 and the slide groove 35, thereby maintaining adjacent rods in a retracted or extended state. The second locking structure may include a telescopic member and a limiting hole for insertion of the telescopic member. The telescopic member is disposed on the second connector 34, and the limiting hole is disposed on the bottom or side wall of the slide groove 35. The limiting hole includes a first limiting hole and a second limiting hole, with the first limiting hole located at a first end and the second limiting hole located at a second end. When the telescopic member is inserted into the first or second limiting hole, the corresponding rod is locked in the retracted or extended position.

[0065] Alternatively, the positions of the limiting hole and the telescopic component can be interchanged. That is, the limiting hole is located on the second connector 34, and the telescopic component is located on the bottom wall or side wall of the slide groove 35. The telescopic component includes a first telescopic component and a second telescopic component. The first telescopic component is located at the first end, and the second telescopic component is located at the second end. When the first telescopic component or the second telescopic component is inserted into the limiting hole, the corresponding rod body is locked in the storage position or the unfolded position.

[0066] The unlocking and locking processes of the second locking structure are the same as those of the first locking structure, and will not be repeated here.

[0067] When the second connector 34 is fixedly connected to either the preceding or following rod, the following rod can only slide away from the connecting structure 10 relative to the preceding rod, but cannot slide towards the connecting structure 10. When the second connector 34 is slidably connected to both the preceding and following rods, the following rod can slide away from the connecting structure 10 relative to the preceding rod, or slide towards the connecting structure 10 relative to the preceding rod, allowing the user to more flexibly shorten the overall length of the rod assembly 30. When the overall length of the rod assembly 30 is too long, the user can directly select a middle rod, slide it towards the connecting structure 10 and lock it, thereby quickly shortening the overall length of the rod assembly 30 without having to slide each rod back from the end one by one.

[0068] The first connector 33 and the second connector 34 can have the same structure. Taking the first connector 33 as an example, in order to prevent the first connector 33 from falling out of the slide groove 35, refer to... Figure 14 The first connector 33 or the second connector 34 can be designed in an "I" shape. Specifically, the first connector 33 includes a web and a first flange and a second flange disposed at both ends of the web. The first flange and the second flange are respectively perpendicular to the web. The groove 35 is shaped like a "T" that can cover the first flange and the second flange. The first flange is held in the groove 35 of the third joint 25, and the second flange is held in the groove 35 of the first rod 31, which can prevent the first connector 33 from falling out of the groove 35. When the first connector 33 needs to be fixed to the third joint 25 or the first rod 31, the first flange or the second flange can be fixed with screws.

[0069] To prevent the lever assembly 30 from accidentally sliding or loosening after extension and locking, thus affecting the shooting experience, anti-slip strips 36 can be provided between the first lever 31 and the third joint 25, between the first lever 31 and the sub-lever 32, and between adjacent sub-lever 32. The anti-slip strips 36 can be made of rubber, silicone, or other materials with a high coefficient of friction. The anti-slip strips 36 increase the friction between adjacent levers, effectively preventing accidental sliding due to external forces (such as hand tremors or wind). Specifically, the anti-slip strips 36 can be continuously or intermittently arranged around the front slide groove 35, the front slide groove 35, or the rear slide groove 35, thus increasing friction without hindering the sliding operation of the lever.

[0070] In this technical solution, a lens 40 is provided on the surface of the connecting structure 10, and the mirror surface of the lens 40 is exposed on the receiving surface. Taking the connecting structure 10 as an example as a patch, the lens 40 can be attached to the side of the patch facing away from the mobile terminal 200 by an adhesive layer. The side of the patch facing away from the mobile terminal 200 is provided with a mounting groove 12 that matches the lens 40, and the lens 40 is embedded in the mounting groove 12. The shape and size of the mounting groove 12 match the shape and size of the lens 40, and the depth of the recess in the mounting groove 12 is equal to or greater than the thickness of the lens 40. The surface of the lens 40 is flush with or slightly lower than the surface of the patch, so that the lens 40 is not easily scratched by other objects or scratches the user during daily use.

[0071] Alternatively, the surface of the patch can have holes, and the lens 40 can be embedded in these holes. Alternatively, the patch itself can be a polished, mirror-like structure, with the mirror surface of the lens 40 facing away from the mobile terminal 200 when the patch is attached to the back of the mobile terminal 200. The lens 40 allows users to check their makeup at any time while taking photos, eliminating the need to carry an additional mirror. Furthermore, because the lens 40 is located on the surface of the patch, users can rotate the mechanism 20 to view their makeup from different angles, such as the front, side, top, and bottom, making it easier to choose the appropriate shooting angle.

[0072] During front-facing shooting, the user may need to adjust the tilt or slant angle of the mobile terminal 200. To avoid interference between the third joint 25 and the side of the mobile terminal 200 during angle adjustment, refer to... Figure 10The third joint 25 has a clearance groove 251 on the side facing the connecting structure 10. When the end of the third joint 25 away from the third pivot 26 is rotated to the front of the mobile terminal 200, the opening of the clearance groove 251 is opposite to the side of the mobile terminal 200, and the width of the clearance groove 251 is greater than the thickness of the mobile terminal 200. The clearance groove 251 provides sufficient space on the side of the mobile terminal 200, allowing the mobile terminal 200 to move freely during pitch adjustment without interfering with the third joint 25.

[0073] This utility model also proposes a mobile terminal kit, which includes a mobile terminal 200 and a mobile terminal photography aid. The specific structure of the mobile terminal photography aid is as described in the above embodiments, and the fixing surface of the connecting structure 10 in the mobile terminal photography aid is attached to the back of the mobile terminal 200. The mobile terminal 200 can be, but is not limited to, a mobile phone, tablet computer, or card camera with a camera function. Specifically, the mobile terminal 200 has a housing, and the fixing surface of the connecting structure 10 is attached to the back of the housing. Since this mobile terminal kit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
