Description

Technical Field

[0002] After retrieval, the patent application with the application number 202123033893.4 discloses a micro anti-shake gimbal and a camera device, including a gimbal base and a base; the gimbal base is provided with a camera module accommodating cavity, and a spherical fulcrum is arranged between the bottom end surface of the gimbal base and the base; a gimbal base driving mechanism for driving the gimbal base to change the tilt angle around the spherical fulcrum is arranged on the base.

[0003] During the use of the micro anti-shake gimbal and the camera device in this patent application, by using the driving method of the micro anti-shake gimbal of the utility model, the rotation angle of the camera module is controlled by the contraction degree of the SMA wire. However, during such use, when the device adjusts the rotation angle of one corner position of the gimbal base, it will force the opposite corner position of the gimbal base to rotate in the corresponding reverse direction. Therefore, the device needs to control the contraction degrees of the two SMA wires at the corresponding positions respectively, and the operation is relatively cumbersome, which brings inconvenience to the use of the device. For this reason, we propose a dual-spectrum thermal imaging micro gimbal device. Summary of the Utility Model

[0018] The utility model provides a dual-spectrum thermal imaging micro pan-tilt device. It has the following beneficial effects:

[0019] 1. This dual-spectrum thermal imaging micro pan-tilt device is provided with an adjustment mechanism. When the tilt angle of the camera module needs to be adjusted, the first adjustment motor can be controlled to drive the upper winding roller to rotate. Since the winding directions of the two first adjustment ropes are opposite, the upper winding roller can reel in one first adjustment rope while releasing the other first adjustment rope, thereby driving the pan-tilt seat to rotate in one direction around the axis of the support ball position to drive the camera module thereon to adjust the tilt angle. Similarly, by controlling the second adjustment motor to drive the lower winding roller to rotate and cooperating with the two second adjustment ropes, the device can rotate in another direction around the axis of the support ball position to drive the camera module thereon to adjust the tilt angle.

[0020] 2. This dual-spectrum thermal imaging micro pan-tilt device is equipped with tension directional wheels. Four tension slide bars drive the four tension directional wheels to resist the two first adjustment ropes and the two second adjustment ropes under the elastic force of four tension springs, so that the two first adjustment ropes and the two second adjustment ropes always remain in a tensioned state to form a limiting effect on the pan-tilt seat, thereby improving the stability of the device structure.

[0028] A dual-spectrum thermal imaging micro pan-tilt device, as Figures 1-4As shown in the figure, it includes a device base 10, a pan-tilt base 11 arranged on the top side of the device base 10, a camera module 12 arranged on the pan-tilt base 11, and a device housing 13 arranged on the outer side of the pan-tilt base 11. Equal-height columns are arranged at the four corner positions of the top wall surface of the device base 10. A shrapnel assembly 14 is arranged between the top end of the pan-tilt base 11 and the top ends of the four columns on the device base 10. A support base 15 is fixedly installed in the middle of the top side of the device base 10 through a bracket. A support ball 16 is movably installed between the middle of the top wall surface of the support base 15 and the middle of the bottom wall surface of the pan-tilt base 11. An upper mounting bracket 17 and a lower mounting bracket 20 are respectively fixedly installed at the middle of the bottom wall surface of the support base 15 and the middle of the top wall surface of the device base 10. An adjusting mechanism for adjusting the tilt angle of the pan-tilt base 11 is arranged on the upper mounting bracket 17 and the lower mounting bracket 20. The adjusting mechanism includes a winding roller 18 and a lower winding roller 21 respectively rotatably installed inside the upper mounting bracket 17 and the lower mounting bracket 20, and two first adjusting ropes 19 and two second adjusting ropes 22 respectively arranged on the upper winding roller 18 and the lower winding roller 21. One ends of the two first adjusting ropes 19 and the two second adjusting ropes 22 away from the upper winding roller 18 and the lower winding roller 21 are respectively fixedly connected to the four corner positions of the bottom wall surface of the pan-tilt base 11. Two winding grooves are opened on the upper winding roller 18. The two first adjusting ropes 19 are respectively wound inside the two winding grooves on the upper winding roller 18 and have opposite winding directions. Two winding grooves are opened on the lower winding roller 21. The two second adjusting ropes 22 are respectively wound inside the two winding grooves on the lower winding roller 21 and have opposite winding directions. A first adjusting motor 23 is fixedly installed on one side wall surface of the upper mounting bracket 17. The output end of the first adjusting motor 23 is fixedly installed with one end of the upper winding roller 18. A second adjusting motor 24 is fixedly installed on one side wall surface of the lower mounting bracket 20. The output end of the second adjusting motor 24 is fixedly installed with one end of the lower winding roller 21. Four tension chutes corresponding to the positions of the two first adjusting ropes 19 and the two second adjusting ropes 22 are respectively opened on the top wall surface of the device base 10 and the bottom wall surface of the support base 15, and four tension sliders 25 are slidably connected inside the four tension chutes.

The camera module 12 and the shrapnel assembly 14 are prior arts and will not be elaborated.

[0029] Working principle of the utility model: When the tilt angle of the camera module 12 needs to be adjusted, the first adjustment motor 23 can be controlled to drive the upper wire winding roller 18 to rotate. Since the winding directions of the two first adjustment ropes 19 are opposite, when the upper wire winding roller 18 winds one first adjustment rope 19, it pays out the other first adjustment rope 19, thereby driving the cloud platform base 11 to rotate around the axis of the support ball 16 in one direction, driving the camera module 12 thereon to adjust the tilt angle. Similarly, by controlling the second adjustment motor 24 to drive the lower wire winding roller 21 to rotate and cooperating with the two second adjustment ropes 22, the device rotates around the axis of the support ball 16 in another direction, driving the camera module 12 thereon to adjust the tilt angle. The above operations are simple and practical, with a reasonable and compact structure, realizing the convenience of the device for adjusting the tilt angle of the camera module 12 and improving the practicability of the device; the four tension slide bars 25 drive the four tension idler wheels 26 to abut against the two first adjustment ropes 19 and the two second adjustment ropes 22 under the elastic force of the four tension springs 27, so that the two first adjustment ropes 19 and the two second adjustment ropes 22 always remain in a tensioned state to form a limiting effect on the cloud platform base 11, improving the stability of the device structure.
