DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0026] See also Figure 1-Figure 7 The simulated eyeball provided in one embodiment of the present invention includes a mounting support 10, an eyeball 20 rotatably connected to the mounting support 10, and an upper eyelid 30 and a lower eyelid 40 cooperating with the eyeball 20.
[0027] In this embodiment, the simulated eyeball of this embodiment also includes a first driving mechanism for driving the eyeball 20 to rotate in the Y-axis direction relative to the mounting support 10, a second driving mechanism for driving the eyeball 20 to rotate in the X-axis direction relative to the mounting support 10, and a third driving mechanism for driving the upper eyelid 30 and the lower eyelid 40 to rotate in the Z-axis direction relative to the eyeball 20, so that when the simulated eyeball of this embodiment is working, the eyeball 20 can rotate in multiple dimensions in space, and the upper eyelid 30 and the lower eyelid 40 can cooperate with the rotation of the eyeball 20, so as to present the effect of blinking the upper eyelid 30 and the lower eyelid 40, so that the overall simulation degree of the simulated eyeball is high.
[0028] The first driving mechanism includes a first steering gear 51 fixed to the mounting support 10, a steering gear bracket 52, and a transmission assembly 53. The first steering gear 51 is connected to the steering gear bracket 52 through the transmission assembly 53, and is used to drive the steering gear bracket 52 to rotate relative to the mounting support 10 in the Y-axis direction.
[0029] Specifically, the transmission assembly 53 includes a base 531, a cover plate 532 covering the base 531, and a gear transmission structure 533 disposed between the base 531 and the cover plate 532. The servo frame 52 is provided with a connecting shaft 521, and the connecting shaft 521 and the rotating shaft of the first servo 51 are respectively connected to the gear transmission structure 533, so that when the first servo 51 of this embodiment is working, the servo frame 52 can be driven to rotate relative to the mounting support 10 in the Y-axis direction through the meshing cooperation between the gears on the gear transmission structure 533. It should be noted that the present embodiment is preferably a one-stage transmission gear structure including two gears. Of course, the gear transmission structure 533 can also be set as a multi-stage transmission gear structure according to the use requirements, which will not be elaborated here.
[0030] The second driving mechanism of this embodiment includes a second servo 61 fixedly connected to the servo bracket 52, and a driving plate 62 arranged on the rotating shaft of the second servo 61, so that when the first driving mechanism is working, the second driving mechanism can be driven by the servo bracket 52 to rotate relative to the mounting support 10 in the Y-axis direction.
[0031] Correspondingly, a limiting slot 21 for accommodating the driving plate 62 is provided on the inner wall of the eyeball 20, and the second servo 61 can drive the eyeball 20 to rotate relative to the mounting support 10 in the X-axis direction through the abutment between the driving plate 62 and the slot wall of the limiting slot 21. It should be noted that the cooperation between the driving plate 62 and the limiting slot 21 is set in the X-axis direction, so that when the second servo 61 drives the driving plate 62 to rotate, the eyeball 20 can be driven to rotate in the X-axis direction through the cooperation between the driving plate 62 and the limiting slot 21 on the eyeball 20.
[0032] Furthermore, the eyeball 20 is provided with a fixing screw (not shown) at the position where the limiting slot 21 is located, and the fixing screw passes through the drive plate 62 and is connected and fixed with the rotating shaft of the second servo 61, so as to achieve relative fixation between the second servo 61 and the drive plate 62 and the eyeball 20. It should be noted that the present embodiment is not limited to connecting and fixing the rotating shaft of the second servo 61 with the drive plate 62 and the eyeball 20 by the fixing screw. Those skilled in the art can directly fix the body of the second servo 61 to the eyeball 20 through a connector according to the needs of use, and at the same time, the drive plate 62 is pressed by the body of the second servo 61 at the position where the limiting slot 21 of the eyeball 20 is located.
[0033] In this embodiment, the upper eyelid 30 has a first connecting member 31 and a second connecting member 32 separated on two opposite sides of the eyeball 20, and the lower eyelid 40 has a third connecting member 41 and a fourth connecting member 42 separated on two opposite sides of the eyeball 20, the first connecting member 31 cooperates with the third connecting member 41, and the second connecting member 32 cooperates with the fourth connecting member 42. Specifically, a rotating shaft 340 is connected between the first connecting member 31 and the third connecting member 41, and / or between the third connecting member 41 and the fourth connecting member 42, and a torsion spring 430 is sleeved on the rotating shaft 340 to open the upper eyelid 30 and the lower eyelid 40. Preferably, the first connecting member 31 and the third connecting member 41, and the second connecting member 32 and the fourth connecting member 42 are respectively connected with the rotating shaft 340, and the torsion spring 430 is set as one. It should be noted that the two hook parts of the torsion spring 430 sleeved on the rotating shaft 340 respectively abut against the first connecting member 31 and the third connecting member 41, and utilize the structure of the torsion spring 430 itself to spread the first connecting member 31 and the third connecting member 41, thereby achieving the effect of spreading the upper eyelid 30 and the lower eyelid 40.
[0034] The arc plate 341 is fixedly connected to the peripheral wall of the rotating shaft 340, and accordingly, the arc groove 301 for accommodating the arc plate 341 is provided on the first connecting member 31 or the third connecting member 41; the limit stopper 342 is fixedly connected to the outer peripheral surface of the arc plate 341, and the angle between the first connecting member 31 and the third connecting member 41 opened by the torsion spring 430 is limited by the collision between the limit stopper 342 and the notch end surface of the arc groove 301. In other words, the opening angle of the upper eyelid 30 and the lower eyelid 40 of this embodiment is limited by the collision between the limit stopper 342 on the rotating shaft 340 and the socket end surface of the arc groove 301 on the first connecting member 31 or the third connecting member 41.
[0035] The first connecting member 31 and the third connecting member 33, and / or the second connecting member 32 and the fourth connecting member 42 are respectively connected with the first eyelid pressing plate 311 and the second eyelid pressing plate 411. Preferably, the first eyelid pressing plate 311 and the second eyelid pressing plate 411 are respectively connected to the second connecting member 32 and the fourth connecting member 42, and the third driving mechanism can push the first eyelid pressing plate 311 and the second eyelid pressing plate 411 to drive the upper eyelid 30 and the lower eyelid 40 to compress the torsion spring 430 to close. It should be noted that the first eyelid pressing plate 311 and the second eyelid pressing plate 411 are arranged on the same plane and bend and extend in two opposite directions, so that the third driving mechanism can act on the first eyelid pressing plate 311 and the second eyelid pressing plate 411 at the same time when working, and realize the synchronous driving of the first connecting member 31 and the third connecting member 41, thereby realizing the synchronous closing drive of the upper eyelid 30 and the lower eyelid 40.
[0036] It should also be noted that the second connecting member 32 is configured to have the same structure as the first connecting member 31, and the third connecting member 41 is configured to have the same structure as the fourth connecting member 42, and the second connecting member 32 and the fourth connecting member 42 are driven to open and close in the same principle as the first connecting member 31 and the third connecting member 41 are driven to open and close, so as to achieve the stability of the upper eyelid 30 and the lower eyelid 40 in opening and closing relative to the eyeball 20. Of course, those skilled in the art can set the second connecting member 32 to have the same structure as the third connecting member 41, and the fourth connecting member 42 to have the same structure as the first connecting member 31 according to the needs of use.
[0037] As can be seen from the above, the third driving mechanism can realize the rotational driving of the upper eyelid 30 and the lower eyelid 40 relative to the eyeball 20 by acting on the first eyelid pressure plate 311 on the first connecting member 31 and the second eyelid pressure plate 411 on the third connecting member 41.
[0038] Specifically, the third driving mechanism includes a third servo 71 fixedly connected to the mounting support 10, a cam 72 arranged on the rotating shaft of the third servo 71, and a pressure plate 73, wherein the pressure plate 73 is arranged on the mounting support 10 in a sliding connection manner, and the pressure plate 73 can push the first eyelid pressure plate 311 and the second eyelid pressure plate 411 along the Z-axis direction; the third servo 71 can push the pressure plate 73 through the cam 72 to move in the Z-axis direction relative to the mounting support 10.
[0039] As a preferred embodiment of the present invention, the simulated eyeball also includes a transparent cover 101, which is covered on the upper eyelid 30 and the lower eyelid 40, and is pressed against the mounting bracket 10 by an outer cover 102, thereby protecting the upper eyelid 30, the lower eyelid 40, and the eyeball 20.
[0040] As can be seen from the above, in this embodiment, the first servo 51 and the second servo 61 for driving the eyeball 20 to rotate, and the third servo 71 for driving the upper eyelid 30 and the lower eyelid 40 to cooperate with the eyeball 20 to blink are independently arranged, so that the simulated eyeball of this embodiment can control the operation of the first servo 51, the second servo 61 and the third servo 71 respectively according to the needs of use, so that the simulated eyeball can effectively imitate the human eyeball when it is working, so that the overall simulation degree of the simulated eyeball is high.
[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
