[0001] This utility model relates to the field of photographic equipment accessories, and in particular to a shooting aid. Background Technology

[0002] With the rise of the short video industry, photo-taking aids are becoming increasingly popular among consumers. Traditional photo-taking aids, however, require customization for different phone sizes, making them unsuitable for all phones and resulting in high production costs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a camera assist device with a locking function that can be adapted to mobile phones of different sizes.

[0004] The present invention relates to a shooting aid comprising: a housing for fitting onto a shooting device, the housing having a locking hole thereon; and a shooting aid handle detachably connected to the housing, wherein a locking member is rotatably disposed therein. One end of the locking member has a locking block, and the other end has a button portion. When the locking block is aligned with the locking hole of the housing, and the button portion is pushed upwards, causing the locking block to move downwards, the locking block is positioned within the locking hole, thereby locking the shooting aid handle onto the housing; when the button portion is pushed downwards, causing the locking block to move upwards and disengage from the locking hole, the shooting aid handle is unlocked from the housing.

[0005] Furthermore, the locking member is a rod with one end protruding downwards to form the locking block; the locking block moves in the opposite direction to the button portion.

[0006] Furthermore, the assist handle also includes a connecting plate, which is detachably secured to the back of the housing;

[0007] The locking element is rotatably mounted on the connecting plate.

[0008] One end of the locking member moves up and down relative to the connecting plate within the assist handle, causing the assist device to switch between a locked state and an unlocked state relative to the housing.

[0009] Furthermore, the connecting plate has a through hole, which communicates with the locking hole;

[0010] The locking block passes through the through hole and is attracted and positioned within the locking hole.

[0011] Furthermore, a positioning magnet is provided inside the locking hole. After the locking block passes through the through hole, it is automatically attracted to the locking hole by the positioning magnet.

[0012] Furthermore, a groove structure that mates with the connecting plate is formed on the surface of the housing opposite to the shooting device, and a protrusion structure is formed on the surface of the connecting plate opposite to the shooting handle.

[0013] During the process of installing the connecting plate of the auxiliary handle onto the housing, the positioning magnet on the housing attracts the auxiliary handle to calibrate the insertion position of the tab structure relative to the groove structure.

[0014] The tab structure engages with the groove structure by external force, thereby mounting the connecting plate on the back of the housing.

[0015] Furthermore, the surface of the connecting plate opposite to the surface where the tab structure is provided is also provided with a mounting portion for mounting the locking member.

[0016] The mounting section includes two parallel plates.

[0017] The locking element is rotatably mounted between the two plates via a hinge shaft.

[0018] Furthermore, one end of one of the plates is provided with a positioning part.

[0019] The positioning part is a cylindrical body perpendicular to the extending direction of the plate, and a spring bead is provided on its end face facing the locking member.

[0020] At least two recesses are formed on one sidewall of the locking member near the locking block. These two recesses are formed by inward recesses from the surface of the sidewall and are interconnected.

[0021] As one end of the locking member moves up and down, the elastic beads will enter the two recesses respectively and slide between the two recesses.

[0022] Furthermore, a fixing member is provided on the back of the housing, and the locking hole is provided on the fixing member.

[0023] Furthermore, the assist handle also includes a handle body, which is a hollow cover, including a flat part and a grip part. The flat part is attached to the back of the housing, and the grip part is a curved structure that protrudes relative to the flat part.

[0024] The button protrudes from a through hole formed in the side wall of the grip.

[0025] As described above, the shooting aid of this utility model has a lever-structured locking component installed inside the shooting handle, and a button is provided on the outer wall of the shooting handle. By pressing the button, the user can use the lever principle to pull the locking block located at its distal end up and down, thereby achieving a locked and unlocked state of the shooting handle relative to the housing. In the locked state, it prevents the shooting handle from sliding relative to the housing, thus preventing offset or wobbling; in the unlocked state, the shooting handle or housing can be easily replaced. Furthermore, this shooting aid is compatible with mobile phones of different sizes, and universal compatibility can be achieved by using a handle body of the same specification, effectively reducing production costs.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figure 1 As shown, this application provides a shooting aid 100 for holding a shooting device, enabling a user to hold the shooting aid with one hand for taking photos. The shooting device described in this application may be, but is not limited to, a smartphone, tablet computer, camera, etc.

[0038] The shooting aid 100 includes a housing 10 and a shooting handle 30. The housing 10 is installed on the back of the shooting device and is used to hold the shooting device. The shooting handle 30 is detachably connected to the housing 10. The shooting handle 30 is the force-bearing part of the user holding the shooting aid 100. Therefore, the shooting handle 30 is selected with a shape suitable for human hand grip, such as an overall curved column shape, and some parts are reserved with grooves for easy gripping.

[0039] Please combine Figure 2 and Figure 3The housing 10 is fitted onto the back of the shooting device and cooperates with the shooting assist handle 30 to achieve the shooting assist function. In this embodiment, the housing 10 is a mobile phone case, but it is not limited to this; it can be any structure as long as it can clamp and fix the shooting device. Multiple groove structures are formed on the outer surface 101 of the housing 10 opposite to the shooting device. In this embodiment, the groove structures include a first groove 131, a second groove 133, and a third groove 135, for engaging with the shooting assist handle 30 (described later). A fixing member 12 is also provided on the outer surface 101 of the housing 10 at positions corresponding to the second groove 133 and the third groove 135. The fixing member 12 is a straight bracket that can pivot and open around one end, serving to support the shooting device in certain usage scenarios. A locking hole 120 is provided on the fixing member 12, which is used to engage with the locking member 33 of the shooting assist handle 30 (described later).

[0040] The housing 10 can be made of alloy, metal, plastic, etc., and has a positioning magnet 121 inside for magnetically locating the locking member 33 of the auxiliary handle 30. It is understood that in other embodiments, the detachable connection between the housing 10 and the auxiliary handle 30 is not limited to magnetic adsorption, but can also be Velcro, riveting, fastening, threaded connection, etc.

[0041] The assist handle 30 includes a handle body 31, a connecting plate 32, and a locking member 33. The handle body 31 is a hollow cover, including a flat portion 311 and a grip portion 312. The flat portion 311 fits against the back of the housing 10, and the grip portion 312 is a curved structure protruding from the flat portion 311, conforming to the shape of a human hand. Four locking posts 313 are formed on the inner surface of the handle body 31 at the positions corresponding to the four feet, which are fixedly connected to the connecting plate 32. In addition, a through hole 310 is provided on the side wall of the grip portion 312 of the assist handle 30.

[0042] The connecting plate 32 is a rectangular plate with engaging sleeves 321 at each of its four corners that mate with the handle body 31. Additionally, on the surface of the connecting plate 32 facing the handle body 31, near one of the engaging sleeves 321, a mounting portion 323 is provided for mounting the locking member 33. The mounting portion 323 includes two parallel, hump-shaped plates 323a. One end of one plate 323a has a positioning portion 323b. The positioning portion 323b is a cylindrical body formed perpendicular to the extending direction of the plate 323a, and a spring bead 324 is provided on its end face facing the locking member 33. The material of the spring bead 324 is not limited, as long as it is made of an elastic and wear-resistant material. In this embodiment, the spring bead 324 is a metal spring bead. Furthermore, both plates 323a have shaft holes 3231.

[0043] By engaging the four engaging pins 313 of the handle body 31 into the four engaging sleeves 321 fitted onto the connecting plate 32, the handle body 31 can be fixed onto the connecting plate 32. Thus, the entire auxiliary handle 30 can be mounted on the back of the housing 10 via the connecting plate 32.

[0044] The locking member 33 is rotatably mounted on the surface of the connecting plate 32 and located within the internal space formed by the connecting plate 32 and the handle body 31. The locking member 33 includes a locking rod 332 and a button portion 333.

[0045] The locking rod 332 is a slender, irregularly shaped rod. One end of the locking rod 332 protrudes downwards, forming a locking block 331; the other end of the locking rod 332 is provided with a button portion 333. The button portion 333 is a rectangular plate that protrudes from a through hole 310 in the side wall of the handle body 31. A shaft hole 3321 is also provided through the locking rod 332 along its minor axis direction perpendicular to its major axis direction. The shaft hole 3321 penetrates through the two side walls of the locking rod 332, providing a hinge shaft 326 (see reference). Figure 4 The locking lever 332 is mounted between two plates 323a via a hinge shaft 326, and both ends of the locking lever 332 can move slightly up and down around the hinge shaft 326, forming a seesaw-like motion.

[0046] Furthermore, a rectangular through hole 320 is provided on the connecting plate 32 near the mounting part 323. This through hole 320 penetrates both the upper and lower surfaces of the connecting plate 32, and its size is the same as the locking hole 120 of the housing 10. Its position corresponds to the locking hole 120 of the housing 10, so that when the connecting plate 32 is installed on the back of the housing 10, the through hole 320 of the connecting plate 32 overlaps with the locking hole 120 of the housing 10. Please refer to [further details]. Figure 4At least two recessed holes 330 are formed on one side wall of the locking lever 332 at a position corresponding to the positioning part 323b of the mounting part 323. The two recessed holes 330 are formed by slightly indenting from the surface of the side wall and are interconnected. The two recessed holes 330 cooperate with the elastic bead 324 to help one end of the locking lever 332 rebound and position itself. More specifically, when the user pushes the button part 333 of the locking member 33 upwards or downwards, the elastic bead 324 moves along with the locking member 33 of the lever structure, alternately entering the two recessed holes 330 and sliding between them. That is, when the button part 333 is moved to the unlocked or locked position, the position of the elastic bead 324 also changes accordingly. Therefore, by engaging the elastic bead 324 of the positioning part 323b with the two recesses 330 on the side of the locking rod 332, the end of the locking rod 332 where the locking block 331 is located can be made to rebound and shift. In addition, when the elastic bead 324 moves from one recess 330 to another recess 330, it will produce a noticeable sound and a click, which can provide tactile feedback when the button part 333 is turned.

[0047] Figure 4 This is a schematic diagram showing the locking element in the locked state. For example... Figure 4 As shown, when the locking member 33 is in the locked state, the locking block 331 passes through the through hole 320 on the connecting plate 32 so as to be attracted and positioned in the locking hole 120 of the housing 10 below the connecting plate 32.

[0048] Figure 5 This is a schematic diagram showing the assembly relationship between the connecting plate 32 and the locking member 33 and the housing 10, where the locking member 33 is in the unlocked state. Figure 5 As shown, in the unlocked state, the end of the locking member 33 with the locking block 331 and the end with the button portion 333 are approximately on the same horizontal plane, thereby disengaging the locking block 331 from the locking hole 120 of the housing 10. Please refer to... Figure 3 , Figure 6 and Figure 7On the surface of the connecting plate 32 that abuts against the back of the housing 10, a first protrusion 325 and a second protrusion 327 are respectively provided on opposite sides of the connecting plate 32. The first protrusion 325 and the second protrusion 327 extend vertically downward from the lower surface of the connecting plate 32 and then horizontally to form a roughly L-shaped protrusion structure. In addition, a notch (not shown) is provided in the middle of the second protrusion 327, so that the second protrusion 327 is divided into a first part 3271 and a second part 3273. When the assist handle 30 is installed on the housing 10, the first protrusion 325 hooks into the first groove 131 of the housing 10, and the first part 3271 and the second part 3273 of the second protrusion 327 hook into the second groove 133 and the second groove 135 of the housing 10, respectively, thereby securing the entire assist handle 30 to the back of the housing 10.

[0049] like Figure 7 (a) and Figure 7 As shown in (b), with the housing 10 and the auxiliary handle 30 assembled together, the first portion 3271 of the first protrusion 325 and the second protrusion 327 on the lower surface of the connecting plate 32 is respectively engaged in the first groove 131 and the second groove 133 on the back of the housing 10. Simultaneously, the second portion 3273 of the second protrusion 327 is engaged in the third groove 135 on the back of the housing 10. Figure 7 Not shown in the image. And, as... Figure 7 As shown in (b), in the unlocked state, the magnetic attraction of the positioning magnet 121 relative to the locking block 331 is released, and the lower end of the locking block 331 disengages from the locking hole 120 and partially extends into the through hole 320; the button part 333 protrudes from the through hole 310 of the assist handle 30 to facilitate user operation.

[0050] The assembly method of the 100 accelerator involved in this utility model will be described below.

[0051] When installing the shooting aid 100, firstly, the locking member 33 is installed on the connecting plate 32 via the hinge shaft 326. Then, the four corner locking posts 313 of the handle body 31 are respectively inserted into the four locking sleeves 321 of the connecting plate 32, thereby fixing the handle body 31 onto the connecting plate 32. Next, the first protrusion 325 and the first portions 3271 and 3273 of the second protrusion 327 on the inner surface of the connecting plate 32 are respectively pushed into the first groove 131, the second groove 133, and the third groove 135 on the back of the housing 10, and secured within these grooves. Thus, the installation of the shooting aid 100 is completed.

[0052] Next, the operating principle of the beater 100 will be explained.

[0053] In such Figure 1In the combined state of the illustrated booster 100, since the button portion 333 of the locking member 33 protrudes from the side wall of the booster handle 30, the user can manually push the button portion 333 upwards to move the end of the locking member 33 equipped with the locking block 331 downwards, passing through the through hole 320 on the connecting plate 32 and entering the locking hole 120 of the housing 10. Thereafter, it is attracted and positioned within the locking hole 120 by the positioning magnet 121. It should be noted that the positioning of the locking block within the locking hole is not necessarily achieved by magnetic attraction; it can also be achieved structurally by moving the button portion 333, such as by triggering a limit lock after moving the button portion 333. This is another type of positioning. Thus, the booster handle 30 can be locked relative to the housing 10. In the locked state, it prevents the booster handle 30 from sliding relative to the housing 10, thus preventing displacement or wobbling. More specifically, during the installation of the connecting plate 32 of the auxiliary shooting handle 100 onto the housing 10, the positioning magnet on the housing 10 attracts the locking block 331 of the locking member 33 mounted on the connecting plate 32, thereby calibrating the insertion position of the protruding structure relative to the groove structure. After the locking member 33 is initially positioned close to the locking hole 120 by magnetic positioning, the user pushes the first protruding piece 325 and the second protruding piece 327 forward, so that they are fully embedded in the remaining space of the grooves (131, 133, and 135). At this time, the locking member 33 of the auxiliary shooting handle 30 and the locking hole 120 of the housing 10 are aligned. Then, the user can achieve true locking by pushing the button part 333 upward. In addition, other groove structures on the housing 10 and protruding structures on the auxiliary shooting handle 100 also have magnetic attraction functions. The magnets arranged on the phone case can automatically attract and initially position the auxiliary shooting handle when it is close. The magnet positioning in this invention has a blind insertion positioning function, allowing users to automatically correct the insertion position of the locking member 33 and other protruding structures through magnetic force without deliberate alignment.

[0054] On the other hand, when unlocking is required, the button 333 can be pushed down by hand, causing the locking block 331 to overcome the attraction of the positioning magnet 121 and tilt upwards to disengage from the locking hole 120 of the housing 10. At this time, the assist handle 30 is in the unlocked state relative to the housing 10. The user can first remove the assist handle 30 from the housing 10, and then remove the connecting plate 32 together with the locking member 33 from the back of the housing 10 to replace the assist handle 30 or the housing 10.

[0055] When the camera assist device 100 needs to be used on electronic devices such as mobile phones, the housing 10 of the camera assist device 100 in its combined state can be fitted onto the electronic device such as mobile phones.

[0056] Preferably, a control circuit board is provided within the photo-taking aid 100. The control circuit board can be housed within the photo-taking handle 30. A signal transmission unit is coupled to the control circuit board, allowing signal transmission between the control circuit board and the mobile phone. For example, the control circuit board can send control information to the mobile phone, such as controlling the mobile phone to take a photo or controlling the start and stop of video recording, or other operations. It should be added that a storage module is provided within the photo-taking aid 100, coupled to the control circuit board. The storage module can send data information to the control circuit board, which then transmits the data information to the mobile phone via the signal transmission unit, allowing the mobile phone to read the data information from the storage module. Similarly, the mobile phone can also send data information to the control circuit board via the signal transmission unit, and the control circuit board can send the data information to the storage module, allowing the storage module to store the data information. Specifically, photos or videos from the mobile phone can be saved in the storage module using the above transmission method, and the mobile phone can also read the photos or videos.

[0057] Understandably, in the above embodiments, the size of the locking hole 120 is slightly larger than the size of the locking block 331, so that the locking block 331 can be automatically attracted into the locking hole 120 by the magnetic attraction of the positioning magnet 121.

[0058] Understandably, the slapping aid 100 of this utility model is detachably snapped together with the multiple protrusions (325, 327) of the connecting plate 32 via multiple grooves 131, 133, 135 provided on the housing 10. Electronic devices of any size and model can be adapted to the slapping aid handle 30 of this embodiment simply by fitting the housing 10 with the grooves shown in this embodiment, thus enhancing its applicability.

[0059] Understandably, the second protrusion 327 provided on the connecting plate 32 can also be a complete engaging piece. That is, it does not have a notch 270 in the middle. Correspondingly, the back of the housing 10, corresponding to the lower end of the connecting plate 32, only needs to be provided with a second groove 133 corresponding to the length of the second protrusion 327.

[0060] Please refer to this as a variation. Figure 2 and Figure 3 To make the camera assist device 100 of this invention adaptable to different mobile phone models, the camera assist device 100 may also exclude the housing 10 and only include the camera assist handle 30. Specifically, the fixing member 12 with locking hole 120 and the connecting plate 32 of the camera assist handle 30 can be integrated as a whole, while omitting the plurality of protrusions on the connecting plate 32. In this case, the fixing member 12 can be fixed to the surface of the connecting plate 32 opposite to the camera assist handle 30 by adhesive bonding, and the fixing member 12 can be made into a magnetic body so that it can be magnetically attached to the back of different mobile phone models.

[0061] In summary, the shooting aid 100 of this utility model has a locking member 33 with a lever structure installed inside the shooting aid handle 30, and a button part 333 is provided on the outer wall of the shooting aid handle 30. By moving the button part 333, the user can use the lever principle to pull the locking block 331 located at its distal end to move up and down. In particular, when the user moves the button part 333, causing the button part 333 to move upward, the locking block 331 moves downward through the through hole 320 and locks in the locking hole 120, thereby preventing the locking member 33 from being pulled out of the shooting aid handle 30, and making the shooting aid handle 30 and the housing 10 form a whole.

[0062] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
