In the field of industrial design, many industrial products often undergo model design, performance simulation, application simulation and other work before actual production, and need to display pictures or videos of the designed products in various occasions to achieve publicity and promotion functions. However, most digital media display stands are often fixedly set, and are usually large in size and weight, suitable for displaying content in fixed positions, and the same device cannot meet the use requirements of flexible transfer in different application occasions. In different applicable occasions, even for the display of the same physical image, it is often necessary to change the display direction or angle of the image so that different observers can clearly and conveniently observe the displayed content from different perspectives. However, since most existing digital media display stands are fixedly installed, the display angle of the display stand is also fixed, and it is impossible to meet the observation needs of different groups of people by adjusting the display position and angle of the display stand. It is often necessary to configure multiple display devices for combined use, which undoubtedly increases the cost investment of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0035] See also Figures 1 to 14 An industrial design display stand that is easy to adjust the posture, including a digital media display screen 100 and a base 1. The digital media display screen 100 adopts an existing commercially available product, which can be any product of wired transmission, wireless transmission, manual button control, touch screen operation, etc., and can project or display conventional electronic files such as text, pictures and videos. The base 1 is a square shell structure with an open top, made of metal or hard plastic material, used to accommodate a scissor-type lifting mechanism 2 and the overall load of the equipment. The horizontal length and width of the base 1 are larger than the length and width of the digital media display screen 100 when it is placed horizontally, and the vertical height of the base 1 is preferably enough to fully accommodate the folded scissor-type lifting mechanism 2.

[0036] Universal wheels 2 are fixedly mounted on the four corners of the bottom surface of the base 1, preferably universal wheels 2 with braking function, so that the device as a whole can be moved and rotated, so as to facilitate the position movement and orientation adjustment of the device as a whole, and to lock the device as a whole in a preset position, so as to facilitate the transfer and use of the device. A shell cover 13 located on the outside of the top of the digital media display screen 100 is detachably connected to the side wall of the base 1, and a handle 14 is rotatably connected to the top surface of the shell cover 13. In this embodiment, the bottom of the outer wall of the shell cover 13 is connected to the outer wall of the base 1 through a built-in spring-type buckle 17. By providing the shell cover 13, a certain protective effect can be achieved for the various internal mechanisms when the device is not in use. By providing the handle 14 on the shell cover 13, the position movement of the device as a whole can be achieved by cooperating with the rolling of the universal wheel 2 through the handle 14. When using the device, open the built-in spring-type buckle 17, and then remove the shell cover 13 from the base 1. The state after removal is as follows. Figure 3 shown.

[0037] A scissor lift mechanism 2 is installed on the top surface of the base 1. The structure of the scissor lift mechanism 2 is similar to the rod hinge structure used in the existing hydraulically driven scissor lift platform. The scissor lift mechanism 2 in this embodiment is unfolded by manual lifting. The connecting rod on the fixed side is hinged to the top surface of the base 1 and the bottom surface of the lifting platform 3 respectively. The bottom and top of the connecting rod on the movable side are provided with a slider and a slot mechanism. The slider is hinged to the bottom and top of the connecting rod on the movable side and is slidably embedded in the slot on the corresponding side respectively. The horizontal position change of the connecting rod of the scissor lift mechanism 2 during the lifting process is adapted by the horizontal linear movement of the slider in the slot. A locking screw (not shown in the figure) is provided on the top of the slider. By tightening the locking screw, the slider can be fastened in the slot, thereby fixing the end of the connecting rod on the movable side of the scissor lift mechanism 2, thereby achieving height adjustment and locking of the scissor lift mechanism 2, and then adjusting the vertical position of the digital media display screen 100, which is convenient for use in different occasions.

[0038] A lifting platform 3 is installed on the top of the scissor-type lifting mechanism 2. The lifting platform 3 is a square shell structure with an open top and front side. It is made of metal or hard plastic material and is used to carry the outer shell 4 and the digital media display screen 100. The end of the top connecting rod on the fixed side of the scissor-type lifting mechanism 2 is hinged to one side of the bottom surface of the lifting platform 3, and the slide groove on the top of the movable side is fixedly installed on the other side of the bottom surface of the lifting platform 3. The vertical lifting of the lifting platform 3 is achieved through the scissor-type lifting mechanism 2. The outer shell 4 is hinged on one side of the top surface of the lifting platform 3. Fig.11 and Fig.12As shown, the outer shell 4 is a square shell structure with one side open, a first hinged head is integrally provided on the outer wall of the bottom side, a first hinged seat is integrally provided on the front side of the top face of the lifting platform 3, the first hinged head and the first hinged seat are hinged by a pin shaft, so that the outer shell 4 can rotate around the axis of the pin shaft there, so as to realize the position adjustment between the horizontal state and the vertical state.

[0039] The outer side of the outer shell 4 (corresponding to Figure 2 A second hinge seat is integrally provided on the bottom surface of the lifting platform 3 in the position shown in the figure. A positioning strut 10 is hinged on the hinge seat through a pin shaft. A horizontally arranged screw rod 11 is rotatably installed in the side wall of the lifting platform 3. A nut block 12 is threadedly connected to the screw rod 11. The end of the positioning strut 10 away from the outer shell 4 is hinged to the top of the nut block 12. In this way, the axis position of the second hinge seat, the axis position of the first hinge seat and the top hinge axis position of the nut block 12 form a triangular structure. The horizontal position of the nut block 12 can be adjusted by rotating the screw rod 11, thereby changing the shape of the triangular structure. The outer shell 4 is pushed to rotate by the positioning strut 10. The nut block 12 can be automatically locked in a preset position by the self-locking characteristics of the threaded transmission. Preferably, the outer end of the screw rod 11 is located on the outer side of the shell cover 13 and is fixedly provided with a knob 15, so that the screw rod 11 can be rotated by manually turning the knob 15. A notch 131 is provided at the bottom of the side wall of the shell cover 13 for the outer end of the screw rod 11 to pass through, so that the shell cover 13 will not interfere with the movement of the screw rod 11 during the process of buckling or removing the shell cover 13 from the base 1.

[0040] When the nut block 12 is located at the inner end of the screw rod 11, the display surface of the digital media display screen 100 is in a nearly vertical state (eg Figure 2 and Figure 3 As shown), when the nut block 12 is located at the outer end of the screw rod 11, the display surface of the digital media display screen 100 is in a nearly horizontal state (as shown in FIG. Figure 4 and Figure 5 In this embodiment, the top hinge axis of the nut block 12 and the hinge axis of the first hinge seat are located in the same horizontal plane. In order to ensure that after the nut block 12 applies a force to the positioning support rod 10, the positioning support rod 10 has an upward component of force on the bottom surface of the outer shell 4, when the nut block 12 is located at the outer end of the screw rod 11, the end of the positioning support rod 10 hinged to the outer shell 4 is located above the end of the positioning support rod 10 hinged to the nut block 12 (as shown in FIG. Figure 2 As shown), that is, the sum of the articulation axis length of the positioning support rod 10 (the straight-line distance between the two parallel articulation axes) and the articulation axis length between the first articulation seat and the second articulation seat is always greater than the articulation axis length between the nut block 12 and the first articulation seat.

[0041] In order to make the outer shell 4 flip to a position close to the vertical state when the nut block 12 is at the innermost end of the screw rod 11, it is necessary to ensure that the hinge axis length of the positioning support rod 10 is not less than the hinge axis length between the first hinge seat and the second hinge seat, and when the nut block 12 is at the outermost end of the screw rod 11, the outer shell 4 can be flipped to a position close to the horizontal state, and the positioning support rod 10 can be close to the horizontal state and stored under the outer shell 4, then the position of the second hinge seat is set at the lower middle part of the outer side surface of the outer shell 4 (such as Fig.11 At the same time, the vertical distance between the axis of the first hinge joint and the outer side of the outer shell 4 is not greater than the vertical distance between the axis of the first hinge seat and the top surface of the lifting platform 3, so that during the rotation of the outer shell 4, its corner will not cause motion interference with the top surface of the lifting platform 3. In order to avoid the outer side of the outer shell 4 from causing motion interference with the screw 11 during the process of flipping to a nearly horizontal state, a strip-shaped opening 403 (as shown in FIG. Fig.11 As shown), the screw rod 11 can partially enter the strip-shaped through hole 403.

Figure 6 and Figure 7 As shown, the rotating bracket 6 is a sheet metal part approximately in the shape of a "cross", and a first threaded hole located on the inside and a first bolt hole located on the outside are provided on each of its four wing plates. The rotating bracket 6 is threadedly connected to the back of the digital media display screen 100 by bolts arranged in the first bolt holes, thereby achieving fixed installation of the rotating bracket 6 on the back of the digital media display screen 100. A circular groove 601 is stamped at the center of the side where the rotating bracket 6 and the back of the digital media display screen 100 are in contact, and a boss 603 corresponding to the groove 601 is formed on the opposite side of the rotating bracket 6. An axial hole 602 is coaxially provided at the center of the boss 603, and a plurality of second bolt holes located on the outside of the axial hole 602 are provided on the end face of the boss 603. As shown in FIG. Fig. 9As shown, a flange connection plate is integrally provided at one end of the rotating shaft 7, and the diameter of the flange connection plate is not greater than the inner diameter of the groove 601, and the axial thickness is not greater than the axial depth of the groove 601, so that the flange connection plate can be completely accommodated in the groove 601, and a second threaded hole matching the second bolt through hole is opened on the end surface of the flange connection plate, and the rotating shaft 7 is fixedly connected to the rotating bracket 6 by a screw arranged in the second bolt through hole and threadedly connected with the second threaded hole. The diameter of the rotating shaft 7 is not greater than the diameter of the shaft hole 602, so that the rotating shaft 7 can extend through the shaft hole 602 to the rear side of the rotating bracket 6 and extend into the bearing installation cylinder 5. The bearing 18 is sleeved on the rotating shaft 7 and embedded in the bearing installation cylinder 5. A shaft shoulder is provided on the shaft diameter of the rotating shaft 7 for positioning one side of the inner ring of the bearing 18, a clamping ring is fixedly sleeved on the rotating shaft 7 for positioning the other side of the inner ring of the bearing 18, and an annular flange is provided on the end surface of the bearing installation cylinder 5 for positioning one side of the outer ring of the bearing 18. The other end of the bearing installation cylinder 5 is provided with a flange connection plate, on which a third bolt through hole is provided, and a third threaded hole matching the third bolt through hole is provided on the rear side wall of the outer shell 4, and the bearing installation cylinder 5 is fixedly installed on the outer shell 4 by screws provided in the third bolt through hole and threadedly connected with the third threaded hole. In this way, the digital media display screen 100 is rotatably installed on the outer shell 4, so that the digital media display screen 100 can freely rotate around the axis of the rotating shaft 7 to adjust its angle posture.

[0043] A rotation positioning cylinder 8 is fixedly connected to the outer side of the rotation bracket 6. Figure 8 As shown, the rotation positioning cylinder 8 is a circular shell structure with an open end face on one side, and a through hole 802 is provided in the end face on the other side. The aperture of the through hole 802 is not less than the outer diameter of the boss 603, so that the rotation positioning cylinder 8 can be sleeved on the outer side of the boss 603. A fourth bolt through hole is provided on the end face of the rotation positioning cylinder 8, which is located outside the through hole 802 and matches the first threaded hole. The screw provided in the fourth bolt through hole is threadedly connected with the first threaded hole, so that the rotation positioning cylinder 8 is fixedly connected to the rotation bracket 6.

[0044] A plurality of positioning holes 801 are provided on the outer circumference of the rotating positioning cylinder 8. In this embodiment, the number of positioning holes 801 is 12 and they are evenly distributed around the axis of the rotating positioning cylinder 8 on the outer circumference of the rotating positioning cylinder 8, so that the rotating positioning cylinder 8 can be rotated 30° at a time to achieve position switching. A positioning pin mechanism 9 matching the positioning holes 801 is movably provided on the side wall of the outer shell 4. Fig.13As shown, the positioning pin mechanism 9 includes a pin shaft 901 movably inserted into the outer shell 4, a handle 902 fixedly connected to the end of the pin shaft 901 and located outside the outer shell 4, and a spring 903 sleeved on the pin shaft 901. The inner end of the pin shaft 901 is provided with a shoulder, and one end of the spring 903 abuts against the shoulder and the other end abuts against the inner wall of the outer shell 4. Fig.12 As shown, a square groove 401 is provided on the top side wall of the outer shell 4, and a pin hole 402 is provided at the bottom of the square groove 401. A pin shaft 901 is movably inserted into the pin hole 402, and its inner side end can be movably inserted into the pin hole 402, so as to realize the circumferential positioning of the rotation positioning cylinder 8. The handle 902 is located on the outer side of the rotation positioning cylinder 8, and its bottom diameter is larger than the diameter of the positioning hole 801 and is threadedly connected with the outer end of the pin shaft 901. By pulling the handle 902 outward, the pin shaft 901 can release the circumferential rotation constraint on the rotation positioning cylinder 8, so that the digital media display screen 100 and the rotation positioning cylinder 8 can rotate around the rotation axis 7 to realize angle adjustment; after releasing the handle 902, the pin shaft 901 is reinserted into the positioning hole 801 under the restoring force of the spring 903, so as to realize the circumferential rotation constraint of the rotation positioning cylinder 8 again.

[0045] Preferably, a buffer pad 19 is fixedly provided on the top surface of the lifting platform 3. The buffer pad 19 is made of flexible rubber or foam material. After the digital media display screen 100 follows the outer shell 4 to flip from a vertical state to a horizontal state, the top surface of the buffer pad 19 abuts against the outer surface of the outer shell 4, thereby playing a limiting and buffering role.

[0046] The device can be easily transferred and fixed, and can be transferred between different display venues to meet the use requirements in different application scenarios; the angle adjustment of the device as a whole is achieved through the universal wheel 16, so as to adjust the viewing direction of the digital media display screen 100 in the horizontal plane, so as to meet the observation needs of observers in different positions during the display of pictures, videos and other information; the position of the positioning support rod 10 is adjusted through the screw 11 and the nut seat 12 to adjust the inclination angle of the display surface of the digital media display screen 100 between the horizontal state and the vertical state, so that the observer can obtain a more suitable viewing angle; through the cooperation between the positioning pin mechanism 9 and the rotating positioning cylinder 8, the display angle of the digital media display screen 100 can be adjusted to meet the observation needs of content display in different azimuth viewing angles. Through the folding and unfolding of the scissor-type lifting mechanism 2, the height change of the digital media display screen 100 can be achieved to meet the use requirements of the observer's downward and horizontal viewing angles.
