Description

Technical Field

[0001] The utility model relates to the field of photographic gimbals, and particularly to a photographic gimbal. Background Art

[0002] A gimbal is a device for fixing electronic products such as mobile phones, cameras, and video cameras, so as to facilitate the adjustment of the horizontal and / or pitching angles of the electronic products during use. The gimbal is usually provided with a knob for adjusting the angle and a rotating shaft mechanism. The user manually rotates the knob, and the knob drives the rotating shaft mechanism to rotate the gimbal, so as to adjust the angle of the electronic device fixed on the gimbal.

[0003] As Figure 1 shown, in the existing gimbal, rotating the knob 1 drives the worm 2 to rotate, the worm 2 drives the worm gear 3 to rotate, and finally the worm gear 3 drives the mounting seat 4 to rotate, so as to realize the angle adjustment of the electronic device located on the mounting seat 4. The worm gear 3 is conventionally set as a 27-tooth gear (international general standard, the minimum number of teeth of the worm gear 3 is 27), and the transmission ratio of the knob 1 to the worm 2 is 1:1. When the user rotates the knob 1 one circle, the worm 2 rotates one circle, the worm 2 drives the worm gear 3 to rotate one tooth, and the corresponding rotation angle of one tooth is 360° / 27 = 13.3°. Therefore, when the user rotates the knob 1 one circle, the electronic device can only be driven to rotate horizontally and / or pitch by 13.3°. When the user needs to rotate the electronic device by a large angle, such as 180°, it takes about 14 circles for the user to manually rotate the knob, which requires a lot of time and energy of the user and affects the user experience of using the gimbal.

[0032] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

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] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0035] The present invention provides a photographic gimbal, as Figures 2 to 4 shown. The photographic gimbal includes a base 100, a first speed regulation mechanism 200, a second speed regulation mechanism 300, and a mounting seat 400. The first speed regulation mechanism 200 is disposed on the base 100, and the first speed regulation mechanism 200 has a first quick adjustment input end 201 and a first output end 202 connected to the second speed regulation mechanism 300. The transmission ratio of the first output end 202 to the first quick adjustment input end 201 is greater than 1. The second speed regulation mechanism 300 has a second quick adjustment input end 301 and a second output end 302 connected to the mounting seat 400. The transmission ratio of the second output end 302 to the second quick adjustment input end 301 is greater than 1, and the rotation axis direction of the second output end 302 is arranged in a crossed state with the rotation axis direction of the first output end 202.

[0036] Among them, the base 100 is used to connect to an external platform, such as a tripod, for the fixation of the photographic pan-tilt head. The connection method can be to set a clamping structure or screws on the base 100. The mounting seat 400 is used to mount photographic equipment, such as a camera. The specific connection method can be to set a clamping structure or screws on the mounting seat 400. Both the first quick-adjust input end 201 and the second quick-adjust input end 301 can adopt the form of a knob to facilitate the user to rotate the first quick-adjust input end 201 and the second quick-adjust input end 301. The first speed regulation mechanism 200 and the second speed regulation mechanism 300 can adopt the same structural form or different structural forms, such as a speed change mechanism with different transmission ratios, specifically a gear speed change mechanism or a planetary gear speed change mechanism, etc. When the first quick-adjust input end 201 and the second quick-adjust input end 301 are rotated one circle, the first output end 202 and the second output end 302 rotate more than one circle, such as two circles, three circles, etc., so that the angle of the camera located on the mounting seat 400 can be adjusted by reducing the number of rotation circles of the first quick-adjust input end 201 and the second quick-adjust input end 301. In addition, the directions of the first speed regulation mechanism 200 and the second speed regulation mechanism 300 for adjusting the camera angle do not coincide. For example, the first speed regulation mechanism 200 is used to adjust the pitching swing of the camera, while the second speed regulation mechanism 300 is used to adjust the left-right swing of the camera, so as to realize the multi-angle adjustment of the camera. Specifically, the directions of the two can be arranged in a vertical state. In this embodiment, the first speed regulation mechanism 200 and the second speed regulation mechanism 300 can increase the rotation speed of the output end, thereby reducing the number of rotation circles when the user adjusts the camera.

[0037] In a preferred embodiment, as Figure 3 shown, the first speed regulation mechanism 200 includes a first mounting frame 210 and a first planetary gear 220. The first mounting frame 210 is arranged on the base 100. At least part of the first planetary gear 220 is arranged on the first mounting frame 210. The input end of the first planetary gear 220 is connected to the first quick-adjust input end 201 and the output end of the first planetary gear 220 is connected to the second speed regulation mechanism 300. Among them, the first planetary gear 220 can adopt a conventional structure. By arranging a part of the first planetary gear 220 on the first mounting frame 210, it is convenient to output more rotation circles by using the first planetary gear 220 after rotating the first quick-adjust input end 201.

[0038] In a preferred embodiment, as Figure 5As shown, the first planetary gear 220 includes a first sun gear 221, a first planetary carrier assembly 222 and a first gear ring 223. The first gear ring 223 is arranged on the first mounting frame 210. The first sun gear 221 is inserted in the first gear ring 223. The first end of the rotating shaft of the first sun gear 221 is connected to the second speed regulating mechanism 300. The first end of the rotating shaft of the first sun gear 221 is the first output end 202. The first planetary carrier assembly 222 is at least partially arranged in the first gear ring 223. The first planetary carrier assembly 222 is respectively connected to the first sun gear 221 and the first gear ring 223 in a transmission manner. The first fast-adjusting input end 201 is connected to the first planetary carrier assembly 222. Among them, the first sun gear 221, the first planetary carrier assembly 222 and the first gear ring 223 adopt a conventional meshing method. At this time, the number of gear teeth in the first planetary carrier assembly 222 is greater than the number of teeth of the first sun gear 221, so as to increase the speed output by the first output end 202. In this embodiment, planetary gears are used as the speed change mechanism, which can effectively reduce the size of the photographic head.

[0039] In a preferred embodiment, if Figure 6 As shown, the first planetary carrier assembly 222 includes a first connecting member 224 and a plurality of first follower teeth 225 rotatably disposed on the first connecting member 224. The plurality of first follower teeth 225 are located in the first gear ring 223 and are arranged around the first sun gear 221. The plurality of first follower teeth 225 are respectively meshed with the first sun gear 221 and the first gear ring 223. One end of the first connecting member 224 away from the first follower teeth 225 is connected to the first quick adjustment input end 201. Preferably, there are three first follower teeth 225, and the number of teeth of the first follower teeth 225 is greater than the number of teeth of the first sun gear 221, so that the first planetary gear 220 is an acceleration mechanism, and compared with the existing gimbal, the camera pitch angle can be adjusted more quickly with fewer turns.

[0040] In a preferred embodiment, if Figure 3 As shown, it preferably also includes a first worm gear assembly 500, and the first output end 202 is transmission-connected to the second speed regulating mechanism 300 through the first worm gear assembly 500. The first worm gear assembly 500 includes a first worm 510 and a first worm wheel 520. The first worm 510 is rotatably arranged on the first mounting frame 210, and the first worm wheel 520 is arranged on the second speed regulating mechanism 300 and meshes with the first worm 510. One end of the first worm 510 is connected to the first output end 202. The self-locking function of the worm gear can effectively prevent the camera from pitching and swinging during operation.

[0041] In a preferred embodiment, if Figure 4As shown, preferably, the second speed adjustment mechanism 300 includes a second mounting bracket 310, a third mounting bracket 320, and a second planetary gear 330. The second mounting bracket 310 is disposed on the base 100. The third mounting bracket 320 is rotatably disposed on the second mounting bracket 310. At least a part of the second planetary gear 330 is disposed on the second mounting bracket 310. The input end of the second planetary gear 330 is connected to the second quick adjustment input end 301. The output end of the second planetary gear 330 is connected to the mounting seat 400. The first worm gear 520 is disposed on the third mounting bracket 320. Among them, the second planetary gear 330 can adopt a conventional structure. By disposing a part of the second planetary gear 330 on the second mounting bracket 310, it is convenient to output more rotation turns by the second planetary gear 330 after rotating the second quick adjustment input end 301.

[0042] In a preferred embodiment, as Figure 7 shown, preferably, the second planetary gear 330 includes a second sun gear 331, a second planetary carrier assembly 332, and a second ring gear 333. The second ring gear 333 is disposed on the second mounting bracket 310. The second sun gear 331 is inserted into the second ring gear 333. The first end of the rotating shaft of the second sun gear 331 is connected to the mounting seat 400. The first end of the rotating shaft of the second sun gear 331 is the second output end 302. At least a part of the second planetary carrier assembly 332 is disposed in the second ring gear 333. The second planetary carrier assembly 332 is respectively in transmission connection with the second sun gear 331 and the second ring gear 333. The second quick adjustment input end 301 is connected to the second planetary carrier assembly 332. Among them, the second sun gear 331, the second planetary carrier assembly 332, and the second ring gear 333 adopt a conventional meshing method. At this time, the number of teeth of the gears in the second planetary carrier assembly 332 is greater than the number of teeth of the second sun gear 331, which is convenient for increasing the rotation speed output by the second output end 302. In this embodiment, using a planetary gear as a speed change mechanism can effectively reduce the volume of the camera pan-tilt head.

[0043] In a preferred embodiment, as Figure 8 shown, preferably, the second planetary carrier assembly 332 includes a second connecting member 334 and a plurality of second follower teeth 335 rotatably disposed on the second connecting member 334. The second follower teeth 335 are located in the second ring gear 333 and are arranged around the second sun gear 331. The plurality of second follower teeth 335 are respectively meshed with the second sun gear 331 and the second ring gear 333. One end of the second connecting member 334 facing away from the second follower teeth 335 is connected to the second quick adjustment input end 301. Among them, preferably, the number of the second follower teeth 335 is three, and the number of teeth of the second follower teeth 335 is greater than the number of teeth of the second sun gear 331, so that the second planetary gear 330 is an acceleration mechanism, and the angle of the camera's left and right swing can be adjusted faster with fewer rotation turns compared to the existing pan-tilt head.

[0044] In a preferred embodiment, as Figure 4 shown, the preferred camera pan-tilt head further includes a second worm and worm gear assembly 600. The second output end 302 is drivingly connected to the mounting base 400 through the second worm and worm gear assembly 600. The second worm and worm gear assembly 600 includes a second worm 610 and a second worm gear 620. One end of the second worm 610 is connected to the second output end 302, and the other end is rotatably arranged on the first mounting bracket 210. The second worm gear 620 is rotatably arranged on the third mounting bracket 320 and meshes with the second worm 610. The second worm gear 620 is connected to the mounting base 400. The first worm gear 520 is rotatably arranged on the second worm 610. By using the self-locking function of the worm and worm gear, the camera can be effectively prevented from swinging left and right during operation.

[0045] In a preferred embodiment, it is preferable that the first planetary gear 220 and the second planetary gear 330 have the same structure, and the first worm and worm gear assembly 500 and the second worm and worm gear assembly 600 also have the same structure. Now, the first planetary gear 220 and the first worm and worm gear assembly 500 will be specifically described. For example, the transmission ratio between the first sun gear 221 and the first follower gear 225 is 2:1, and the transmission ratio between the first worm 510 and the first worm gear 520 is 40:3. Specifically, when the first quick adjustment input end 201 rotates one circle (i.e., 360°), the first follower gear 225 drives the first sun gear 221 to rotate two circles. The rotating shaft of the first sun gear 221 correspondingly drives the first worm 510 to rotate two circles. The first worm 510 drives the first worm gear 520 to rotate 2 gears. The corresponding rotation angle of the 2 gears is (360° / 27)*2 = 26.6°. The camera correspondingly pitches and swings 26.6°. When the second quick adjustment input end 301 rotates one circle (i.e., 360°), the second follower gear 335 drives the second sun gear 331 to rotate two circles. The rotating shaft of the second sun gear 331 correspondingly drives the second worm 610 to rotate two circles. The second worm 610 drives the second worm gear 620 to rotate 2 gears. The corresponding rotation angle of the 2 gears is (360° / 27)*2 = 26.6°. The camera correspondingly swings left and right 26.6°.

[0046] In a preferred embodiment, as Figure 3 、 Figure 4 、 Figure 9 and Figure 10As shown, preferably, the first mounting bracket 210 has a first mounting cavity 211. The first worm 510, the first worm gear 520, and the first planetary gear 220 are all located in the first mounting cavity 211. The second mounting bracket 310 has a second mounting cavity 311, and the second planetary gear 330 is located in the second mounting cavity 311. The third mounting bracket 320 has a third mounting cavity 321 that communicates with the first mounting cavity 211 and the second mounting cavity 311 respectively. The second worm and the second worm gear are both located in the third mounting cavity 321. Among them, the first mounting bracket 210 includes a bottom plate 212 and a bracket 213 provided on the bottom plate 212. The first mounting cavity 211 is provided on the bracket 213. The first mounting cavity 211 is in an inverted T shape. The first worm 510 and the first planetary gear 220 are located in the lower part of the first mounting cavity 211, and the first worm gear 520 is located in the upper part of the first mounting cavity 211. The second mounting bracket 310 and the bracket 213 are spaced apart on the bottom plate 212. The third mounting bracket 320 is in an overall inverted T shape. One end of the two ends of the lower part of the third mounting bracket 320 penetrates into the first mounting cavity 211 and is connected to the side surface of the first worm gear 520, and the other end is rotatably connected to the second mounting bracket 310. Moreover, the third mounting cavity 321 is also in an inverted T shape. The two ends of the lower part of the third mounting cavity 321 communicate with the first mounting cavity 211 and the second mounting cavity 311 respectively. The second worm gear 620 is located in the upper part of the third mounting cavity 321, and the second worm 610 is located in the lower part of the third mounting cavity 321. In addition, since there is a certain space between the second mounting bracket 310 and the bracket 213, a spirit level can also be provided on the bottom plate 212 and between the second mounting bracket 310 and the bracket 213, so as to facilitate the user to adjust the placement position of the camera according to the spirit level. In this embodiment, by providing the first mounting cavity 211, the second mounting cavity 311, and the third mounting cavity 321 to cover components such as the first worm 510, the first worm gear 520, the first planetary gear 220, the second planetary gear 330, the second worm 610, and the second worm gear 620, it is beneficial to prevent foreign matters such as dust from affecting the operation of the camera head, playing a role in dust prevention.

The second end of the rotating shaft of the first sun gear 221 sequentially passes through the first connecting member 224 and the first fast adjustment input end 201 to be connected to the first slow adjustment input end 203. In this embodiment, the first slow adjustment input end 203 and the first sun gear 221 are coaxially arranged, that is, when the first slow adjustment input end 203 rotates one circle, the second sun gear 331 also rotates one circle. When the first slow adjustment input end 203 and the first fast adjustment input end 201 are rotated by the same number of circles respectively, the number of circles output by the first output end 202 is different, so as to facilitate providing multiple choices for the user to adjust the camera angle, that is, it has the functions of fast adjustment and fine adjustment. In addition, there is no need to separately set a speed change mechanism, that is, a speed change structure (i.e., a planetary gear) can output two different speeds, which can effectively reduce the volume of the pan-tilt. At this time, the first slow adjustment input end 203, the first fast adjustment input end 201 and the first planetary gear 220 are all located at the same end of the first worm 510. The first fast adjustment input end 201 is located between the first slow adjustment input end 203 and the first planetary gear 220. A plurality of lever handles are spaced on the outer peripheral side of the first fast adjustment input end 201. The specific form can refer to the grip on the rudder to facilitate controlling the rotation of the first fast adjustment input end 201. The outer peripheral side of the first slow adjustment input end 203 is provided with anti-slip lines to increase the friction when rotating the first slow adjustment input end 203.

[0048] In a preferred embodiment, as Figure 4As shown, it preferably further includes a second slow adjustment input end 303, and the second slow adjustment input end 303 is located on the side of the second fast adjustment input end 301 away from the second sun gear 331. The second end of the rotating shaft of the second sun gear 331 sequentially passes through the second connecting member 334 and the second fast adjustment input end 301 and is connected to the second slow adjustment input end 303. Among them, the second slow adjustment input end 303 is preferably a knob, so as to facilitate adjusting the angle of the camera by rotating the knob. At this time, it is preferably that the second connecting member 334 and the first fast adjustment input end 201 are provided with through holes, so that the second end of the rotating shaft of the second sun gear 331 can sequentially pass through the above through holes and then be connected to the second slow adjustment input end 303. In this embodiment, the second slow adjustment input end 303 and the second sun gear 331 are coaxially arranged, that is, when the second slow adjustment input end 303 rotates one circle, the second sun gear 331 also rotates one circle. When the second slow adjustment input end 303 and the second fast adjustment input end 301 are rotated by the same number of turns respectively, the number of turns output by the second output end 302 is different, so as to facilitate providing multiple options for the user to adjust the camera angle, that is, it has the functions of fast adjustment and fine adjustment. In addition, there is no need to separately set a speed change mechanism, that is, a planetary gear can output two different speeds by using a speed change structure, which can effectively reduce the volume of the pan-tilt. At this time, the second slow adjustment input end 303, the second fast adjustment input end 301 and the second planetary gear 330 are all located at the same end of the second worm 610. The second fast adjustment input end 301 is located between the second slow adjustment input end 303 and the second planetary gear 330. A plurality of handlebars are spaced on the outer peripheral side of the second fast adjustment input end 301. The specific form can refer to the grip on the rudder, so as to facilitate controlling the rotation of the second fast adjustment input end 301. The outer peripheral side of the second slow adjustment input end 303 is provided with anti-slip lines to increase the friction when rotating the second slow adjustment input end 303.

The second locking member is disposed on the second mounting bracket 310 and can be used to lock the rotation of the second planetary gear set 332. Wherein, the first driving motor and the second driving motor can both be selected as motors with self-locking functions, so that the first ring gear 223 and the second ring gear 333 can rotate during manual adjustment. When driven by the first driving motor and the second driving motor, the first locking member and the second locking member are respectively used to lock the rotation of the first planetary gear set 222 and the second planetary gear set 332, so as to facilitate the first driving motor and the second driving motor to drive the first ring gear 223 and the second ring gear 333 to rotate respectively, thereby driving the first sun gear 221 and the second sun gear 331 to rotate respectively. In addition, the first locking member and the second locking member can be screws. By screwing the screws, the ends of the screws are abutted against the first planetary gear set 222 and the second planetary gear set 332, thereby restricting the rotation of the two and realizing locking. In this embodiment, the automatic adjustment method by the driving motor is beneficial to realizing the automation of the camera pan-tilt head. Moreover, in the case where the driving motor cannot operate, manual adjustment can also be performed.

[0050] In a preferred embodiment, it is preferable that the base 100 is rotatably connected to the first mounting bracket 210. A third locking member (not shown in the figure) for locking the rotation of the first mounting bracket 210 is disposed on the base 100 or the first mounting bracket 210. Wherein, it is preferable that the first mounting bracket 210 can rotate around the vertical direction, so as to facilitate the horizontal rotation of the camera. The third locking member can restrict the rotation of the first mounting bracket 210 when the camera rotates to an appropriate position. Specifically, the third locking member can be a component such as a screw. At this time, a rotating shaft is disposed on the first mounting bracket 210. The first mounting bracket 210 is rotatably connected to the base 100 through the rotating shaft. By screwing the screw to abut against the rotating shaft, the rotation of the first mounting bracket 210 can be restricted.
