Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] This utility model embodiment provides a shooting auxiliary device 1000, such as... Figure 1 and Figure 2 As shown, the shooting auxiliary device 1000 includes a grip 100, a first connecting arm 200, a fan 300, and a fixing structure 400. One end of the first connecting arm 200 is connected to the top of the grip 100. The first connecting arm 200 has an air inlet 210 connecting its inner and outer sides. The fan 300 is installed inside the first connecting arm 200. The fixing structure 400 is used to fix the shooting terminal. The fixing structure 400 includes a base 410 for contacting the shooting terminal. The base 410 is rotatably connected to the other end of the first connecting arm 200 to adjust the roll angle of the fixing structure 400. The interior of the base 410 communicates with the interior of the first connecting arm 200 so that the air blown by the fan 300 enters the interior of the base 410 through the first connecting arm 200. The base 410 has an air outlet 411 connecting its inner and outer sides.

[0019] By implementing this embodiment, when the fan 300 is running, it can guide air from the air inlet 210 into the first connecting arm 200. After entering the first connecting arm 200, the air is accelerated by the fan 300, and the accelerated air can pass through the first connecting arm 200 into the base 410, and then be discharged from the base 410 through the air outlet 411. Therefore, implementing this embodiment can utilize the fan 300 to dissipate heat from the base 410.

[0020] Specifically, when the shooting terminal is mounted on the fixed mechanism, it comes into contact with the base 410. Therefore, the heat from the shooting terminal is transferred to the base 410. Thus, cooling the base 410 is equivalent to cooling the shooting terminal. It is evident that the shooting auxiliary device 1000 provided in this embodiment can cool the shooting terminal by cooling the base 410, which helps improve the stability of the shooting terminal, avoids overheating to a certain extent, and reduces the probability of shooting stuttering or interruption.

[0021] refer to Figure 2 and Figure 3 In a specific embodiment, the shooting auxiliary device 1000 also includes a first drive motor 510. The base 410 is rotatably connected to the other end of the first connecting arm 200 through the first drive motor 510. The center of the first drive motor 510 has a first through hole 511, and the two sides of the first through hole 511 are respectively connected to the interior of the first connecting arm 200 and the interior of the base 410.

[0022] This embodiment illustrates a specific implementation in which the interior of the first connecting arm 200 is connected to the interior of the base 410. Specifically, the interior of the first connecting arm 200 and the interior of the base 410 are connected by a first through hole 511 located at the center of the first drive motor 510, so that the wind accelerated by the fan 300 can enter the interior of the base 410 from the interior of the first connecting arm 200.

[0023] Since most handheld stabilizers involve using a drive motor to adjust the roll angle of the fixed structure 400, the specific structure, driving method, and installation method of the first drive motor 510 in this embodiment are common knowledge to those skilled in the art, and will not be described in detail here.

[0024] In another embodiment, the base 410 and the other end of the first connecting arm 200 are rotatably connected via a damping shaft (not shown in the figure), so that the fixing structure 400 can be fixed after the user manually adjusts the roll angle of the fixing structure 400. More specifically, a third through hole (not shown in the figure) is provided at the center of the damping shaft, and the two sides of the third through hole are respectively connected to the interior of the first connecting arm 200 and the interior of the base 410.

[0025] This embodiment illustrates a specific implementation in which the interior of the first connecting arm 200 is connected to the interior of the base 410. Specifically, the interior of the first connecting arm 200 and the interior of the base 410 are connected by a third through hole at the center of the damping shaft.

[0026] Since most selfie sticks involve adjusting the roll angle of the fixed structure 400 using a damping pivot, the specific structure and installation method of the damping pivot in this embodiment are common knowledge to those skilled in the art, and will not be described in detail here.

[0027] refer to Figure 3 and Figure 4 In a specific embodiment with a first drive motor 510, the first connecting arm 200 is provided with two air guide walls 220, which are spaced apart to form an air guide channel 230 between them. The fan 300 is provided on one side of the air guide channel 230, and the first through hole 511 is provided on the other side of the air guide channel 230.

[0028] By implementing this embodiment, the air accelerated by the fan 300 is constrained by the two air guide walls 220, thereby entering the first through hole 511 along the air guide channel 230. This helps to reduce air dissipation, reduce unnecessary air flow, and increase the air flow rate after entering the base 410, thereby improving the heat dissipation effect.

[0029] refer to Figure 5 In some embodiments, the base 410 includes a mating surface 412 facing away from the other end of the first connecting arm 200, and a peripheral surface 413 surrounding the mating surface 412. The mating surface 412 is provided with an air outlet groove 4121, which communicates with the peripheral surface 413. An air outlet 411 is disposed at the bottom of the air outlet groove 4121.

[0030] Specifically, the contact surface 412 will come into contact with the shooting terminal during use. Therefore, by implementing this embodiment, the air blown out from the air outlet 411 can not only take away the heat of the base 410, but also directly act on the shooting terminal, thereby taking away the heat of the shooting terminal.

[0031] It should be noted that, in order to ensure that the air can be smoothly discharged after acting on the shooting terminal, this embodiment also provides an air outlet groove 4121 on the bonding surface 412. The air outlet groove 4121 is connected to the peripheral surface 413 surrounding the bonding surface 412. In this way, the air blown out from the air outlet 411 will enter the air outlet groove 4121 and come into contact with the shooting terminal. After completing the heat exchange, it will be discharged from the peripheral surface 413, thus avoiding heat accumulation.

[0032] refer to Figure 6 and Figure 7In some embodiments, the base 410 includes a first inner sidewall 414, which is disposed inside the base 410 on the side away from the first connecting arm 200. The interior of the base 410 has a heat-conducting metal sheet 415 that abuts against the first inner sidewall 414. This allows air entering the base 410 to exchange heat with the heat-conducting metal sheet 415 before being discharged through the air outlet 411.

[0033] This embodiment demonstrates a specific implementation method for efficiently removing heat from the base 410. Specifically, during use, heat from the shooting auxiliary device is transferred to the first inner wall 414, and then to the heat-conducting metal sheet 415. Because the heat-conducting metal sheet 415 has high thermal conductivity, heat is evenly distributed within it. Air entering the base 410 comes into contact with the uniformly heated heat-conducting metal sheet 415, efficiently removing heat and expelling it from the air outlet 411. This facilitates better heat dissipation for the shooting terminal, thereby reducing the probability of shooting stuttering or interruptions. The heat-conducting metal sheet 415 can be made of copper, which has good thermal conductivity, or aluminum, which has good thermal conductivity and is relatively lightweight; this embodiment does not impose any limitations.

[0034] refer to Figure 6 and Figure 7 In a specific embodiment, the base 410 includes a housing 416 and a cover plate 417. One side of the housing 416 is rotatably connected to the other end of the first connecting arm 200. The other side of the housing 416 is provided with an installation groove (not shown in the figure) for the heat-conducting metal sheet 415 to be installed in the housing. The cover plate 417 is placed on the other side of the housing, thereby limiting the heat-conducting metal sheet 415 to be installed in the base 410.

[0035] In this embodiment, the side of the cover plate 417 facing away from the first connecting arm 200 is the side that contacts the shooting terminal, and the side of the cover plate 417 facing the first connecting arm 200 is the first inner sidewall 414. The heat from the shooting terminal is transferred to the heat-conducting metal sheet 415 through the cover plate 417, and then exchanges heat with the air accelerated by the fan 300, and finally is discharged through the air outlet 411.

[0036] refer to Figure 8 In some embodiments, a plurality of spaced heat dissipation fins 4151 are provided on the side of the heat-conducting metal sheet 415 facing the first connecting arm 200.

[0037] Specifically, setting heat dissipation fins 4151 can increase the surface area of ​​the heat-conducting metal sheet 415, thereby increasing the heat exchange between the heat-conducting metal sheet 415 and the air. Therefore, by implementing this embodiment, heat exchange can be more efficient, which is beneficial for better heat dissipation of the shooting terminal, thereby reducing the probability of shooting stuttering and shooting interruption.

[0038] refer to Figure 2 , Figure 6 and Figure 8 In a specific embodiment, a plurality of heat dissipation fins 4151 are positioned in a first direction ( Figure 2 and Figure 8 The heat exchange fins 4151 are spaced apart in the X direction (as shown), forming a heat exchange duct 4152 arranged in the second direction between any two adjacent heat exchange fins 4151. Two air outlets 411 are provided, and the two air outlets 411 are arranged in the second direction (…). Figure 2 and Figure 8 The second direction is perpendicular to the first direction.

[0039] Specifically, after the air is blown between the two heat dissipation fins 4151, it will flow along the heat exchange air duct 4152 in the second direction to both sides of the heat exchange air duct 4152. The air on both sides of the heat exchange air duct 4152 is not only in different positions, but also flows in different directions. If only one air outlet 411 is provided, it will obviously be not conducive to the rapid exhaust of air, which will greatly reduce the heat dissipation effect. Therefore, this embodiment provides two air outlets 411. The two air outlets 411 are respectively provided on both sides of the base 410 in the second direction, so that the air on both sides of the heat exchange air duct 4152 can be quickly exhausted from the base 410 through the two air outlets 411, resulting in excellent heat dissipation effect.

[0040] Therefore, by implementing this embodiment, heat exchange can be carried out more efficiently, which is beneficial for better heat dissipation of the shooting terminal, thereby reducing the probability of shooting stuttering and shooting interruption.

[0041] refer to Figure 1 In some embodiments, the fixing structure 400 further includes two clamping blocks 420 respectively disposed on both sides of the base 410, the two clamping blocks 420 being used to clamp the shooting terminal.

[0042] This embodiment demonstrates a specific implementation method for fixing a shooting terminal using a fixing structure 400. Specifically, two clamping blocks 420 disposed on both sides of the base 410 are used to clamp the two sides of the shooting terminal, thereby fixing the shooting terminal.

[0043] In a specific embodiment, one of the clamping blocks 420 can slide relative to the other clamping block to adjust the distance between the two clamping blocks 420, so that the fixing structure 400 can be adapted to shooting terminals of different sizes, improving the versatility of the fixing structure 400 and providing a better user experience.

[0044] In another embodiment, the two clamps 420 can slide relative to each other to adjust the distance between the two clamps 420, so that the fixing structure 400 can be adapted to shooting terminals of different sizes, improving the versatility of the fixing structure 400 and providing a better user experience.

[0045] In some embodiments, the fixing structure 400 further includes a magnetic suction element (not shown) for attaching the shooting terminal.

[0046] This embodiment demonstrates a specific implementation of fixing a shooting terminal using a fixing structure 400. Specifically, the shooting terminal is magnetically attracted using a magnetic attachment provided on the base 410. More specifically, when the user needs to fix the shooting terminal, they only need to place the shooting terminal on the base 410, and the magnetic attachment on the base 410 will attract the shooting terminal, thus fixing it to the base 410. When the user no longer needs to use the shooting terminal, they only need to forcefully pull it off to separate the shooting terminal from the fixing structure 400. The advantage of this embodiment is that the installation and removal of the shooting terminal are very convenient.

[0047] refer to Figure 1 and Figure 9 In some embodiments, the shooting assistance device 1000 further includes a second connecting arm 600, a second drive motor 520, and a third drive motor 530. One end of the second connecting arm 600 is rotatably connected to the top of the grip 100 via the second drive motor 520 to adjust the yaw angle of the second connecting arm 600. The other end of the second connecting arm 600 is rotatably connected to one end of the first connecting arm 200 via the third drive motor 530 to connect one end of the first connecting arm 200 to the top of the grip 100 and to adjust the pitch angle of the first connecting arm 200.

[0048] By implementing this embodiment, the shooting terminal can be adjusted in multiple dimensions, resulting in a better user experience. Specifically, by implementing this embodiment, the pitch angle, roll angle, and yaw angle of the shooting terminal are all adjustable, thereby achieving multi-dimensional adjustment of the shooting terminal. More specifically, the roll angle of the shooting terminal can be adjusted by the first drive motor 510, the yaw angle can be adjusted by the second drive motor 520, and the pitch angle can be adjusted by the third drive motor 530.

[0049] refer to Figure 2 and Figure 10 In a specific embodiment, the third drive motor 530 has a second through hole 531 at its center. The two sides of the second through hole 531 are respectively connected to the interior of the first connecting arm 200 and the interior of the second connecting arm 600. The shooting auxiliary device 1000 also includes a sealing plug 700, which is plugged at the second through hole 531.

[0050] The sealing plug 700 is placed at the second through hole 531, which effectively restricts the air accelerated by the fan 300 from flowing into the interior of the second connecting arm 600, ensuring one-way airflow, reducing kinetic energy loss, and facilitating better heat dissipation for the shooting terminal, thereby reducing the probability of shooting stuttering and shooting interruption.

[0051] It should be noted that, since the first drive motor 510 requires power, existing technology typically involves threading a wire through the second through hole 531 to supply power to the first drive motor 510. To ensure that the sealing plug 700 blocks the second through hole 531 without affecting the wire's passage, in a specific embodiment, a sealing plug 700 can be integrally injection molded around the wire, allowing the wire to pass through the sealing plug 700. This way, the sealing plug 700 blocks the second through hole 531 without affecting the wire's passage.

[0052] refer to Figure 1 In some embodiments, a tripod 800 is provided at the bottom of the grip 100. This allows the shooting aid 1000 to be used not only by hand but also placed on a table or the ground. Therefore, by implementing this embodiment, the usage scenarios of the shooting aid 1000 are expanded, resulting in an excellent user experience.

[0053] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
