Description

Technical Field

[0001] The utility model belongs to the field of image acquisition devices, and particularly relates to a fixing device for acquiring images during movement. Background Art

[0002] With the development of technologies such as artificial intelligence and AI, the simulation robot technology has also been rapidly improved. In order to better train artificial intelligence for training and learning, in some links, it is necessary for humans to wear image acquisition devices and cooperate with the surrounding environment. Through the movements of parts such as the head, neck, chest, and hands, the AI program of the simulation robot can obtain the movement habits of people, and then control the robot to perform simulation. During this process, it is necessary for people to wear an image acquisition device on the head so that the AI program can obtain the images that can be observed by the human eye and the visual image information after the human body makes a reaction. Then, in cooperation with the image acquisition modules arranged around, the limb movements made when people see the changes in the scene in front of them are obtained, so that the simulation robot can imitate human movements. Since during this process, parts such as the head, neck, and torso of people will make different movements, and even the movement amplitudes are relatively large, it is necessary for the image acquisition device worn by people to have a relatively tight connection with the head. Although there are some wearable products that can fix the camera on the head, due to the loose connection with the head, when there are large movements of the head, due to the large inertia of the camera movement, it is easy to cause the camera to shake or even fall off, which causes trouble to the acquisition of images during people's movement. Moreover, the existing devices fixed on the head are relatively complicated to wear. Summary of the Utility Model

[0003] In view of this, the utility model aims to provide a fixing device for acquiring images during movement, so that the image acquisition device and the human head can be worn more quickly, facilitating people to acquire the images in front of them during movement, and at the same time making the connection between the device and the human body closer.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0016] A second wedge-shaped protrusion extends outwards from the end of the non-return claw. A force-receiving surface is arranged on the second wedge-shaped protrusion, and the force-receiving surface is opposite to the vertical surface of the first wedge-shaped protrusion.

[0017] Furthermore, a gap is left between every two adjacent wedge-shaped protrusions, and the width of the gap is greater than the width of the non-return claw.

[0018] Further, a plug hole is formed in the middle of the rotating shaft core, and a limiting edge extends inwards from the outer end of the plug hole; a plugging portion extends vertically downwards from the middle of the anti-reverse cover, and barbs are arranged outwards at the end of the plugging portion, and the barbs can abut against the limiting edge.

[0036] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] The fixing device for collecting images during movement according to the present utility model includes

[0038] The fixing seat 1 of the image acquisition module 4, which includes a bottom plate 11 and two oppositely arranged fixing pieces 12 vertically extending from both ends of the bottom plate 11, and mounting holes are respectively formed in the two fixing pieces 12. During use, the image acquisition module 4 is installed between the two fixing pieces 12 through cooperation. In this embodiment, in order to make the collected image information more conform to the image observed by the human eye, the image acquisition module 4 is a binocular camera composed of two cameras, and short shafts are respectively provided at both ends of the image acquisition module 4. The short shafts are inserted into the mounting holes, and the image acquisition module 4 can rotate around the short shafts. A thread is formed on one of the short shafts, and the short shaft passes through the fixing piece 12 and is screwed with a knob 15. The angle of the image acquisition module 4 is fixed by the way of clamping the fixing piece 12 by the knob 15 and the image acquisition module 4. Arc-shaped clamping parts 13 respectively extend outwards from both ends of the bottom plate 11 of the fixing seat 1 of the image acquisition module 4, and the ends of the two clamping parts 13 are connected by a locking rope 2, so that the locking rope 2 and the two clamping parts 13 can enclose a ring. In application, the image acquisition module 4 is fixed on the head of the experimenter through the two clamping parts 13. In this embodiment, the locking rope 2 can be a rope loop, and holes are formed at the ends of the two clamping parts 13, and the rope loop is connected to the clamping parts 13 through the holes; it can also be a single or multiple separate locking ropes 2, and both ends of each locking rope 2 are fixed to the clamping parts 13 by means of sewing, buckling, bonding, etc.

[0039] The locking part 3 includes a base 31, a winding coil 32 and a non-return cover 33. An accommodation space 311 is formed in the base 31, the winding coil 32 is placed in the accommodation space 311, and a rotating shaft core 315 extends vertically upward from the bottom of the accommodation space 311. Two blocking pieces 323 are arranged inside the winding coil 32. Each blocking piece 323 respectively includes an arc-shaped positioning part and stress parts 3232 at both ends of the positioning part, and the blocking piece 323 is connected to the winding coil 32 as a whole through the stress parts 3232. The arc top parts of the two blocking pieces 323 are respectively placed on the periphery of the rotating shaft core 315, and the winding coil 32 is sleeved on the rotating shaft core 315 through the arc-shaped part 3231. A space is left between the arc-shaped part 3231 and the inner wall of the winding coil 32, and a threading space 324 is formed by surrounding the inner wall of the winding coil 32 by the blocking piece 323. A through hole 322 is formed in the side wall of the winding coil 32, and the through hole 322 is placed in the threading space 324. The locking rope 2 can pass through the through hole 322 and enter the threading space 324, preventing the locking rope 2 from interfering with the rotating shaft core 315 during the rotation of the winding coil 32, resulting in wear of the locking rope 2 and the occurrence of disordered wires. A through hole 322 is also formed in the side wall of the base 31 for passing through the locking rope 2. A wire groove 321 is formed on the outer wall of the winding coil 32. When the winding coil 32 rotates, the locking rope 2 can be placed in the wire groove 321 to prevent the locking rope 2 from being disordered. The center of the non-return cover 33 extends vertically downward to form a plug-in part 333. The plug-in part 333 includes at least two plug-in pieces 3331, and a deformation space is left between every two adjacent plug-in pieces 3331. Barbs 3332 are arranged outward at the end of the plug-in part 333. A plug-in hole 316 is formed in the middle of the rotating shaft core, and a limiting edge 317 extends inward from the outer end of the plug-in hole 316. The plug-in part 333 can be inserted into the plug-in hole 316, and when the non-return cover 33 moves outward to the limit position, the barbs 3332 can abut against the limiting edge 317. A spring 34 is arranged between the base 31 and the non-return cover 33, and one end of the spring 34 abuts against the non-return cover 33 and the other end abuts against the base 31. More specifically, the spring 34 is placed in the plug-in hole 316, one end of the spring 34 abuts against the bottom of the accommodation hole, and the other end abuts against the non-return cover 33.A plurality of first wedge-shaped protrusions 312 are provided along the circumference at the top of the side wall of the base 31, and a gap is left between every two adjacent first wedge-shaped protrusions 312; a check claw 331 extends vertically downward from the edge of the check valve cover 33, and a second wedge-shaped protrusion 332 extends outward from the bottom end of the check claw 331. The inclined surface 3121 of the first wedge-shaped block corresponds to the inclined surface 3121 of the second wedge-shaped protrusion 332, and the inclined surfaces 3121 of the two wedge-shaped protrusions are parallel to the rotation axis core 315, so that during the rotation of the check valve cover 33, the inclined surfaces 3121 of the two wedge-shaped protrusions can cause the check claw 331 to elastically deform in the radial direction of the check valve cover 33 after contact, enabling the check valve cover 33 to smoothly rotate in the first direction. The first wedge-shaped block further includes a vertical surface 3122, and there is an included angle between the vertical surface 3122 and the rotation axis of the coil 32, and the vertical surface 3122 faces the outside of the accommodation space 311. A force-receiving surface 3321 is provided on the second wedge-shaped protrusion 332, and the force-receiving surface 3321 faces the vertical surface 3122 of the first wedge-shaped protrusion 312, so that when the check valve cover 33 rotates in the second direction or receives an external force in the axial direction, the force-receiving surface 3321 and the vertical surface 3122 come into contact with each other and form a component force that pushes the check valve cover 33 outward. Due to the cooperation of the limit edge 317 and the barb 3332, the check valve cover 33 is fixed in place to prevent the accidental loosening between the second wedge-shaped block and the second wedge-shaped block, resulting in the loosening of the locking rope 2; and the width of the check claw 331 is smaller than the width of the gap between the two first wedge-shaped protrusions 312, so that the second wedge-shaped protrusion 332 can pass through the gap. When the check valve cover 33 is pressed forcefully or the check valve cover 33 is first rotated in the second direction and then pressed downward, the two wedge-shaped protrusions are separated from each other, enabling the check valve cover 33 to rotate in the second direction and causing the locking rope 2 to loosen. The check valve cover 33 further extends downward to form a force-receiving piece 335. There is a force-receiving space 325 left between two opposite force-receiving portions 3232 of the coil 32, and the bottom end of the force-receiving piece 335 can be inserted into the force-receiving space 325, enabling the check valve cover 33 to rotate synchronously with the coil 32. When the first wedge-shaped protrusion 312 and the second wedge-shaped protrusion 332 cooperate with each other, the bottom end of the force-receiving piece 335 contacts the top of the force-receiving portion 3232. When the first wedge-shaped protrusion 312 and the second wedge-shaped protrusion 332 are separated from each other, the force-receiving piece 335 can extend into the force-receiving space 325.

[0040] The fixing device for collecting images during movement according to the present invention further includes an arc-shaped positioning piece 14. The positioning piece 14 is disposed between the ends of the two clamping portions 13, and the base 31 of the locking portion 3 is fixedly connected to the positioning piece 14. The clamping portions 13 and the positioning piece 14 are respectively wrapped with fabric and / or sponge pads. The locking rope 2 can be placed between the fabric clamps of the positioning piece 14.

[0041] The fixing device for collecting images during movement according to the present utility model, during use, the experimenter wears it on the head and positions the image acquisition module 4 at the forehead. Then, the anti-reverse cover 33 is tightened in the first direction to prevent the image acquisition module 4 from loosening. After that, the binocular camera is rotated so that the image collected by the binocular camera is similar to the image observed by the experimenter himself. Then, corresponding movements are performed, such as dodging, turning the head, lowering the head, etc. in the face of a suddenly approaching object, so that the image acquisition module 4 can collect visual images during the movement of the experimenter. The collected images can be stored in the internal storage module of the image acquisition module 4, or can be connected to an external storage or image processing device by wired or wireless means. It should be noted that the specific methods of storing, transmitting, and processing images are all prior arts in this field, and the transmission, storage, and processing of images are not the problems to be solved by this application. Therefore, the specific methods are not elaborated here. After the image acquisition is completed, just press the anti-reverse cover 33 with greater force or rotate the anti-reverse cover 33 in the second direction and then press the anti-reverse cover 33, so that the first wedge-shaped protrusion 312 and the second wedge-shaped protrusion 332 are separated, causing the anti-reverse cover 33 to rotate in the second direction and the locking rope 2 to loosen, generally for removing the device from the head.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
