Description

Technical Field

[0001] The utility model relates to the technical field of remote control consoles for deep-sea operating equipment, in particular to a display tilt adjustment mechanism. Background Art

[0002] In recent years, the strategic value of deep-sea mineral resource development has become increasingly prominent. Due to its own mechanical limitations, humans cannot work directly on the seabed. Deep-sea mineral resource development generally requires the use of deep-sea robots or other marine industrial equipment. Marine workers remotely operate these deep-sea operating equipment through a control console on a surface vessel (platform). The console is equipped with display devices, communication equipment, various control handles, etc. Among them, the display, as the human-computer interaction interface, is what marine workers need to pay constant attention to. Marine operations often require long operating times. In order to reduce the operator's physical fatigue, the ergonomic design of the operating table is very important. An important aspect is that the tilt angle of the display can be adaptively adjusted according to the operator's different height and sitting posture or changes in ambient light.

[0003] like Figure 1 As shown, the tilt adjustment mechanism of the existing console is relatively simple. It mainly connects the rotating bracket 200 with the long arc hole and the mounting bracket 400 by fastening the screw 300. The display 100 is installed on the rotating bracket 200. The tilt angle of the display 100 is adjusted by changing the relative position of the rotating bracket 200 and the mounting bracket 400. The left and right sides cannot be adjusted synchronously, and two-handed operation is required. The adjusted tilt angle is difficult to grasp and multiple adjustments are required to obtain the appropriate angle. In addition, the connection is unreliable and the display is prone to sliding and displacement. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a display tilt adjustment mechanism with compact structure, high stability and convenient operation in view of the shortcomings of the existing adjustment mechanism.

[0007] As a further improvement of the present invention, the adjustment assembly includes a turntable, a reversing knuckle, a support arm, a driven nut block, a transmission screw and a transmission wheel group; the driven nut block is rotatably set on the transmission screw, one end of the support arm is rotatably connected to the driven nut block, one end of the support arm is rotatably connected to one end of the reversing knuckle, and the other end of the reversing knuckle is rotatably connected to the second movable bracket; the two ends of the transmission screw are respectively connected to the fixed bracket, the transmission wheel group is arranged on the inner side wall of the fixed bracket, the turntable is arranged on the outer side wall of the fixed bracket, and the transmission wheel group is respectively connected to the turntable and the transmission screw; when the turntable is rotated, the transmission wheel group drives the transmission screw to rotate, and the driven nut block drives the support arm to rise and fall, so as to realize that the second movable bracket drives the display to adjust the tilt angle.

[0008] As a further improvement of the present invention, a shoulder is provided on the transmission screw, which is used to divide the transmission screw into two symmetrical parts, wherein a part connected to the moving nut block is provided with a thread, and the other part is set as an optical axis.

[0009] As a further improvement of the present invention, two support arms and two driven nut blocks are provided. When the transmission wheel group drives the transmission screw to rotate, the two driven nut blocks move closer to or away from each other to achieve synchronous lifting of the two support arms.

[0010] As a further improvement of the present invention, a shoulder is provided on the transmission screw, which is used to divide the transmission screw into two symmetrical parts, one part of which is provided with a left-handed thread and the other part is provided with a right-handed thread. The two driven nut blocks respectively have left-handed threads and right-handed threads that are adapted to the transmission screw. When the transmission screw rotates, the two driven nut blocks approach or move away from each other.

[0011] As a further improvement of the present invention, the thread on the transmission screw is a self-locking thread.

[0012] As a further improvement of the present invention, the transmission wheel set includes a driving gear and a driven gear that mesh with each other. The connecting shaft of the driving gear passes through the side wall of the fixed bracket and is fixed to the turntable. The driven gear is nested in the end of the transmission screw.

[0013] As a further improvement of the present invention, a handle is provided on the turntable.

[0014] As a further improvement of the present invention, the turntable is connected to a motor drive assembly, and the motor drive assembly is used to drive the turntable to rotate forward and reverse, so that the transmission wheel group drives the transmission screw to rotate forward and reverse.

[0015] As a further improvement of the present invention, the first movable bracket is provided with a plurality of first connection holes for connecting to the display, and the second movable bracket is provided with a plurality of second connection holes for connecting to the display.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The display tilt adjustment mechanism of the present invention improves the support stability of the display by arranging the first movable bracket and the second movable bracket on the same side of the fixed bracket for connecting the display. At the same time, one end of the adjustment component is connected to the fixed bracket, and the other end of the adjustment component is connected to the second movable bracket; when the adjustment component is rotated, the second movable bracket can drive the display to rotate around the rotation axis between the first movable bracket and the fixed bracket, thereby realizing the tilt adjustment of the display. Moreover, the display can be automatically fixed after being adjusted into place, which is easy to operate and has high adjustment flexibility.

[0018] 2. The display inclination adjustment mechanism of the present invention can be operated with one hand. The rotating handle drives the turntable to rotate, and then the transmission wheel group drives the transmission screw to rotate, so that the inclination angle of the display can be adjusted. Since the pitch of the thread transmission is relatively small, the adjustment process is softer and smoother. The inclination angle can be increased or decreased at any time, and the change is continuous, making it easy to achieve a comfortable viewing angle. Because the driven nut block can only be driven to move by the transmission screw, it can be self-locked when the handle is not operated, and the inclination angle will not change due to the gravity of the display, thereby improving the reliability of the display adjustment.

[0029] Example

[0030] like Figure 2 、 Figure 3 and Figure 4As shown, the display tilt adjustment mechanism of the present invention includes: a first movable bracket 1, a fixed bracket 2, a second movable bracket 4 and an adjustment component. Among them, the two fixed brackets 2 are symmetrically arranged, and a mounting hole 10 is provided at the bottom of the fixed bracket 2. By screwing a fastener into the mounting hole 10, the fixed bracket 2 can be installed and fixed on the operating table. The two ends of the first movable bracket 1 are respectively connected to the fixed bracket 2 through a rotating shaft 102. The rotating shaft 102 between the first movable bracket 1 and the fixed bracket 2 is the rotation axis for adjusting the angle of the display 100. Moreover, the first movable bracket 1 and the second movable bracket 4 are both arranged on the same side of the fixed bracket 2 for connecting the display 100, that is, there are two connection points between the adjustment mechanism and the display 100, so as to improve the support stability of the adjustment mechanism for the display 100, and also facilitate the position of the display 100 to be fixed after the tilt is adjusted. One end of the adjustment component is connected to the fixed bracket 2, and the other end of the adjustment component is connected to the second movable bracket 4; when the adjustment component is rotated, the second movable bracket 4 drives the display 100 to rotate around the rotation axis 102 between the first movable bracket 1 and the fixed bracket 2, so as to adjust the inclination angle of the display 100 and fix it.

[0031] It can be understood that in order to meet the installation requirements of different displays, in other embodiments, the first movable bracket 1 and the second movable bracket 4 can be made into an integrated structure, and a transition mounting plate is installed thereon. The transition mounting plate can be replaced to adapt to the installation interface of different displays.

[0032] In this embodiment, by arranging the first movable bracket 1 and the second movable bracket 4 on the same side of the fixed bracket 2 for connecting the display 100, the support stability of the display 100 is improved. At the same time, one end of the adjustment component is connected to the fixed bracket 2, and the other end of the adjustment component is connected to the second movable bracket 4; when the adjustment component is rotated, the second movable bracket 4 can drive the display 100 to rotate around the rotating axis between the first movable bracket 1 and the fixed bracket 2, thereby realizing the inclination adjustment of the display 100, and it can be automatically fixed after being adjusted into place, which is easy to operate and has high adjustment flexibility.

[0033] like Figure 3 As shown, in this embodiment, the first movable bracket 1 is provided with a plurality of first connection holes 101 for connecting to the display 100 , and the second movable bracket 4 is also provided with a plurality of second connection holes 401 for connecting to the display 100 .

[0034] like Figure 2As shown, the adjustment assembly includes a turntable 3, a reversing joint 5, a support arm 6, a driven nut block 7, a drive screw 8, and a transmission wheel assembly 9. The driven nut block 7 is rotatably mounted on the drive screw 8. One end of the support arm 6 is rotatably connected to the driven nut block 7, which in turn is rotatably connected to one end of the reversing joint 5. The other end of the reversing joint 5 is rotatably connected to the second movable bracket 4. The reversing joint 5 is primarily used to adapt to changes in the angle between the second movable bracket 4 and the support arm 6 during tilt adjustment. The support arm 6 restricts the driven nut block 7 from rotating with the drive screw 8. Furthermore, as the driven nut block 7 moves on the drive screw 8, the position of the support reversing joint 5 and the second movable bracket 4 changes, achieving angle adjustment. Both ends of the drive screw 8 are fixed to the fixed bracket 2 via bearings. The transmission wheel assembly 9 is mounted on the inner wall of the fixed bracket 2, and the turntable 3 is mounted on the outer wall of the fixed bracket 2. The transmission wheel assembly 9 is connected to the turntable 3 and the drive screw 8, respectively. When the turntable 3 is rotated, the transmission wheel set 9 drives the transmission screw 8 to rotate, and the driven nut block 7 drives the support arm 6 to rise and fall, so that the second movable bracket 4 drives the display 100 to adjust the tilt angle.

[0035] like Figure 3 and Figure 5 As shown, two support arms 6 and two driven nut blocks 7 are provided. When the transmission wheel group 9 drives the transmission screw 8 to rotate, the two driven nut blocks 7 are close to or away from each other to achieve the synchronous lifting of the two support arms 6.

[0036] like Figure 6 As shown, the drive screw 8 is provided with a shoulder 11, which is used to divide the drive screw 8 into two symmetrical parts, one of which has a left-handed thread and the other has a right-handed thread. The two driven nut blocks 7 have left-handed and right-handed threads respectively adapted for the drive screw 8. When the drive screw 8 rotates, the two driven nut blocks 7 can move synchronously toward the center of the drive screw 8 or toward the ends, moving closer to or farther from each other, thereby achieving tilt adjustment of the display 100.

[0037] Furthermore, the thread on the transmission screw 8 is a self-locking thread, and when the transmission screw 8 stops rotating, locking is achieved.

[0038] In other embodiments, under the premise that the structural strength is met, only one support arm 6 and only one driven nut block 7 can be provided, and the shoulder 11 is used to divide the transmission screw 8 into two symmetrical parts, wherein a part connected to the moving nut block 7 is provided with a thread, and the other part is set as an optical axis.

[0039] like Figure 4As shown, the transmission wheel assembly 9 includes a driving gear 901 and a driven gear 902 that mesh with each other, and the diameter of the driving gear 901 is larger than the diameter of the driven gear 902, and the number of teeth of the driving gear 901 is also greater than the number of teeth of the driven gear 902. The connecting shaft of the driving gear 901 passes through the side wall of the fixed bracket 2 and is connected and fixed to the turntable 3. The driven gear 902 is nested in the end of the transmission screw 8. A handle 301 is provided on the turntable 3 for manual rotation operation. The driving gear 901 is coaxially connected to the turntable 3, and the transmission wheel assembly 9 is used to increase the speed, which can reduce the number of handle turns of the second movable bracket 4 from the maximum inclination angle to the minimum inclination angle to improve the adjustment efficiency.

[0040] like Figure 3 and Figure 5 As shown, the turntable 3 has "up" and "down" operation marks for easy operation. The angle can be adjusted with one hand, and the operator can check whether the angle is adjusted properly while adjusting. This avoids the operator's complicated operation of holding the display 100 with one hand and turning the left and right fastening screws in turn with the other hand, and avoids the inefficient operation of adjusting first and then checking and repeating the adjustment multiple times. Compared with the past, the human-machine efficiency is greatly improved.

[0041] In other embodiments, the turntable 3 can also be connected to a motor drive assembly that can rotate forward and reverse, and the motor drive assembly is used to drive the turntable 3 forward and reverse, so that the transmission wheel set 9 drives the transmission screw 8 forward and reverse. In this case, in order to make the adjustment smooth and gentle, it is necessary to replace the transmission gear set 9 with a reduction gear set and set an appropriate reduction ratio according to the motor selection.

[0042] In this embodiment, the adjustment process of the display tilt adjustment mechanism is as follows:

[0043] (1) When the handle 301 drives the turntable 3 to rotate in the upward direction, the driven gear 902 is driven by the driving gear 901 to rotate at an accelerated speed ratio, driving the transmission screw 8 to rotate. The two driven nut blocks 7 move synchronously toward the middle of the transmission screw 8. The two support arms 6 also retract with the driven nut blocks 7, and the second movable bracket 4 is lifted up, thereby driving the display 100 to rotate around the rotation axis of the first movable bracket 1, and the angle with the horizontal plane increases; Figure 3 and Figure 4 shown.

[0044] (2) When the handle 301 drives the turntable 3 to rotate in the downward direction, the two driven nut blocks 7 move synchronously toward the two ends of the transmission screw 8, and the two support arms 6 also expand outward along with the driven nut blocks 7, and the position of the second movable bracket 4 descends, thereby driving the angle between the display 100 and the horizontal plane to become smaller; Figure 5 and Figure 6 shown.

[0045] (3) When the handle 301 and the turntable 3 are not operated, the driven nut block 7 and the transmission screw 8 are self-locked by the thread, and the driven nut block 7 will not move on the transmission screw 8 due to the gravity of the display 100, thereby achieving self-locking of the inclination angle of the display 100.

[0046] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
