[0036] 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.

[0037] Example 1: Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, is an electronic product display visual presentation device, comprising a display base 1 and a display screen 2, wherein the display screen 2 comprises a housing 21, a main display screen 22, and a secondary display screen 23, wherein the two secondary display screens 23 are arranged side by side on the back of the main display screen 22, and a supporting plate 24 is used to protect the main display screen 22, and can also play a supporting role for subsequent structures;

[0038] The upper and lower positions of the main display screen 22 are connected with supporting plates 24, the housing 21 is assembled on the display base 1, the supporting plates 24 slide along the housing 21, and the auxiliary display screen 23 slides along the supporting plates 24 to adjust the position of the auxiliary display screen 23;

[0039] The supporting plate 24 moves toward the inside of the housing 21 to store the superimposed main display screen 22 and the auxiliary display screen 23 into the housing 21, and the supporting plate 24 moves toward the outside of the housing 21 to leave a gap between the main display screen 22 and the housing 21 for the auxiliary display screen 23 to move out;

[0040] By moving the supporting plate 24 outward, the main display screen 22 can be moved outward to cooperate with the sub-display screen 23 to increase the display screen, and the main display screen 22 can be moved inward so that both the sub-display screen 23 and the main display screen 22 can be stored in the outer shell 21 to reduce the floor space. At the same time, the sub-display screen 23 and the main display screen 22 can also be protected by the outer shell 21 to facilitate the movement of the equipment.

[0041] The auxiliary display screen 23 slides out from the gap to a position parallel to the main display screen 22 to increase the displayable image, and the auxiliary display screen 23 slides from the gap to the back of the main display screen 22 to reduce the displayable image.

[0042] The two supporting plates 24 are fixed by a support frame 25, and the support frame 25 is connected to the cylinder in the shell 21. The support frame 25 and the supporting plates 24 are driven by the cylinder to slide synchronously along the width direction of the shell 21 to receive the display screen 2 into the shell 21 or push it out of the shell 21.

[0043] The support frame 25 provides support for the supporting plate 24 at the upper and lower positions, and the cylinder drives the support frame 25 to move after receiving the control signal.

[0044] The auxiliary display screen 23 and the supporting plate 24 are connected via a connecting rod assembly 3, wherein the connecting rod assembly 3 includes a limit sliding block 1 31, a limit sliding block 2 32 and a connecting rod 33, and two ends of the connecting rod 33 are movably connected to the limit sliding block 1 31 and the limit sliding block 2 32. The shaft fixed at one end of the auxiliary display screen 23 is inserted into the bearing on the top surface of the limit sliding block 1 31, and the shaft of the auxiliary display screen 23 can rotate around the limit sliding block 1 31 to adjust the angle of the auxiliary display screen 23.

[0045] Both ends of the two supporting plates 24 are connected to the baffle 4, and the baffle 4 is also connected to the slider on the inner wall of the shell 21. The baffle 4 serves the purpose of supporting the plates 24 to avoid the problem of low support strength caused by relying solely on the cylinder for support. The baffle 4 and the supporting plates 24 form a frame structure for increasing the support strength. The opposite end surfaces of the supporting plates 24 are provided with grooves 7.

[0046] The axis of one end of the auxiliary display screen 23 is connected to the limit sliding block 1 31, which is used for the auxiliary display screen 23 to rotate around the axis. The bottom ends of the limit sliding block 1 31 and the limit sliding block 2 32 are both stuck in the groove 7 and slide. The setting of the groove 7 can limit the sliding trajectory of the limit sliding block 1 31 and the limit sliding block 2 32, and at the same time, it can also prevent the limit sliding block 1 31 and the limit sliding block 2 32 from detaching from the groove 7, which is used to provide support for the unfolded auxiliary display screen 23.

[0047] Both ends of the groove 7 have a 90° bend angle. The limiting sliding block 1 31 moves into the 90° bend angle, while the limiting sliding block 2 32 does not move into the 90° bend angle, and the edges of the auxiliary display screen 23 and the main display screen 22 are flush.

[0048] In this embodiment, one or two auxiliary display screens 23 are provided. If one auxiliary display screen 23 is provided, the length of the auxiliary display screen 23 is smaller than the length of the main display screen 22. If two auxiliary display screens 23 are provided, the length of the auxiliary display screen 23 is smaller than half of the main display screen 22.

[0049] The following example shows two secondary display screens 23:

[0050] The cylinder pushes the screen to move outside the shell 21, and a gap is left between the main display screen 22 and the shell 21 for the auxiliary display screen 23 to move out. By pulling out the two auxiliary display screens 23, the limit sliding block 1 31 and the limit sliding block 2 32 slide in opposite directions along the groove 7. Since a channel for accommodating the auxiliary display screen 23 is left between the baffle 4 and the main display screen 22, during the sliding process of the auxiliary display screen 23, it can be pulled out straight when passing through the baffle 4 and the main display screen 22. When the limit sliding block 1 31 moves to the 90° bend position of the groove 7 (this position is set as the translation point), the limit sliding block 1 31 and the limit sliding block 2 32 are located at the same position of the groove 7. A horizontal groove, at this time, the edges of the auxiliary display screen 23 and the main display screen 22 are consistent, and the auxiliary display screen 23 continues to be pulled. At this time, the limit sliding block 31 will move to the 90° bend of the groove 7, and the auxiliary display screen 23 moves in the "L" trajectory in the groove 7, so that the screens of the auxiliary display screen 23 and the main display screen 22 are in a flush position (this position is set as the expansion point). The display screen is increased by the two auxiliary display screens 23. At the same time, the angles of the two auxiliary display screens 23 can also be adjusted. The two auxiliary display screens 23 are tilted and displayed on the outside of the observer in a surrounding manner with the main display screen 22, so that the observer is immersed in the scene and the display and visual presentation effects are enhanced.

[0051] When the two auxiliary display screens 23 need to be folded up, the auxiliary display screen 23 is pushed to move in the gap, and the limit sliding block 31 of the auxiliary display screen 23 moves from the unfolding point to the translation point. In the channel between the baffle plate 4 at one end of the auxiliary display screen 23 and the main display screen 22, the roller at the bottom of the main display screen 22 is continued to be pushed to contact the auxiliary display screen 23 to reduce damage to the auxiliary display screen 23. After being guided, the auxiliary display screen 23 rotates around the axis in the opposite direction, and adjusts the angle to be parallel to the main display screen 22 and moves into the channel. When the auxiliary display screen 23 is completely moved to the back of the main display screen 22, the screen is driven by the cylinder to move toward the shell 21 until the main display screen 22 and the supporting plate 24 seal the opening of the shell 21.

[0052] Through the above structure, one screen can be used for display, or multiple screens can be displayed, with high display flexibility. The visual presentation effect is improved by the tilt angle of the secondary display screen 23. At the same time, when the screen is folded, the floor space is reduced, which makes it easier to move the device, and the folded screen can also be protected by the outer shell 21.

[0053] Example 2: Reference Figure 5-Figure 6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment, and the first embodiment needs to be manually pulled out;

[0054] In this embodiment, a motor is installed on one of the baffles 4, and a transmission shaft 41 connected to the motor penetrates into the bearings of the two baffles 4. A locking sleeve 321 is fixed on the limiting sliding block 32, and an external thread is provided on the transmission shaft 41. The locking sleeve 321 is cylindrical and engages with the external thread of the transmission shaft 41. The rotation of the transmission shaft 41 is used to push the locking sleeve 321, the connecting rod assembly 3 and the auxiliary display screen 23 to move synchronously, so as to unfold or fold the auxiliary display screen 23.

[0055] The external threads of the two sub-display screens 23 are meshed with each other in opposite directions. In this embodiment, the transmission shaft 41 is driven to rotate by a motor, and the locking sleeve 321 is meshed with the transmission shaft 41. When the motor is started, the sub-display screens 23 on both sides can be driven to move toward or oppositely at the same time, and the problem that the sub-display screens 23 are difficult to pull out in a narrow gap can be avoided. Electronic control does not require manual operation, which is more intelligent.

[0056] Example 3: Reference Figure 7-Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment because the angle of the secondary display screen 23 needs to be manually adjusted after the secondary display screen 23 is unfolded in the second embodiment.

[0057] In this embodiment, the groove 7 passes through the supporting plate 24, and the auxiliary display screen 23 is provided with one or two pieces. The shaft connecting the auxiliary display screen 23 and the limit sliding block 1 31 passes through the groove 7 and is connected to the bracket 5. A gear is fixed on the shaft of the auxiliary display screen 23. The bracket 5 is also provided with two shafts, and gears are fixed on both shafts. One of the shafts is movably connected to the bearing of the limit sliding block 2 32, and the three gears are meshed in sequence. In the process of sliding the limit sliding block 1 31 and the limit sliding block 2 32, the three gears always remain in a meshing state;

[0058] The transmission shaft 41 is provided with a threaded portion and a smooth portion, a smooth portion is provided between two adjacent threaded portions, a locking sleeve 321 is meshed with the threaded portion 1, a threaded portion 2 of the transmission shaft 41 is meshed with the sleeve 6, a limiting plate 61 is fixed on the outer circumference of the sleeve 6, a ring body 62 penetrated by the transmission shaft 41 is also movably connected on the side circumference of the sleeve 6, a side surface of the ring body 62 is connected to a push ring 63 through a telescopic rod, a spring sleeved on the telescopic rod is also provided between the ring body 62 and the push ring 63, and the spring is located on the outer side of the smooth portion;

[0059] The ring body 62 does not contact the transmission shaft 41, and the sleeve 6 can rotate around the ring body 62, but the two will not separate. The rack 621 connected to the bottom end of the limit plate 61 is engaged with the gear on the limit sliding block 2 32, and the upper and lower plates that limit the rotation of the rack 621 are also fixed on the side of the baffle 4.

[0060] The following is an example of two secondary display screens 23:

[0061] When the secondary display screen 23 is unfolded:

[0062] The transmission shaft 41 is provided with three threaded parts and two smooth parts, and the two smooth parts separate the three threaded parts. When the secondary display screen 23 needs to be unfolded, the transmission shaft 41 rotates, and the two locking sleeves 321 on the middle threaded part of the transmission shaft 41 move in opposite directions. The locking sleeve 321 moves from the middle threaded part toward the smooth part on one side. Since the sleeve 6 is on the smooth part, the rotation of the transmission shaft 41 will not drive the sleeve 6 to move. When the limit sliding block 31 moves to the translation point of the groove 7, the locking sleeve 321 is still on the threaded part, and the locking sleeve 321 continues to move. When the limit sliding block 31 has not moved to the unfolding point, the locking sleeve 321 contacts with the push ring 63 and moves with it. As the locking sleeve 321 continues to move, the spring is slowly compressed, and the pressure applied to the push ring 63 is slowly increased. The thread of the sleeve 6 slowly contacts the thread of the transmission shaft 41. Under the action of pressure, the sleeve 6 will first rotate along the transmission shaft 41, and the rack 621 will rotate synchronously with the sleeve 6. After the rack 621 rotates, it will be blocked by the lower plate and cannot continue to rotate. At this time, the sleeve 6 will slowly screw on the thread, and the sleeve 6 will move in a straight line along the supporting plate 24. The push ring 63 and the locking sleeve 321 keep moving synchronously, and the locking sleeve 321 continues to move until it moves to the smooth part. At this time, the thread direction of the locking sleeve 321 is the same as the rotation direction of the thread cloth, and the auxiliary display screen 23 moves to the expanded position and stops.

[0063] As the sleeve 6 continues to move along the support plate 24, the elastic force of the spring gradually decreases until the push ring 63 is disengaged from the locking sleeve 321. At this time, the movement of the rack 621 will push the gear to rotate, thereby achieving the simultaneous rotation of the two auxiliary display screens 23 at the same angle to reduce the angle between the two auxiliary display screens 23 and the main display screen 22. There is no need to manually adjust the angle of the two auxiliary display screens 23, avoiding the problem of inconsistent adjustment angles.

[0064] When the secondary display screen 23 needs to be folded:

[0065] When the transmission shaft 41 rotates in the opposite direction, the sleeve 6 will drive the rack 621 to rotate synchronously with the transmission shaft 41 first. After the rack 621 disengages from the gear, it rotates to contact the upper plate body. At this time, the center of gravity of the rack 621 deviates, and the rack 621 always maintains an upward position. Then the sleeve 6 will move in the opposite direction along the supporting plate 24, and the push ring 63 will contact the locking sleeve 321. At this time, the elastic force of the spring slowly increases. After the sleeve 6 moves from the threaded portion to the smooth portion, the locking sleeve 321 is screwed onto the transmission shaft 41 under the action of pressure. The locking sleeve 321 will move along the upper transmission shaft 41 to drive the secondary display screen 23 to move into the gap, and after passing the main display screen 22, the secondary display screen 23 will rotate and be limited to a position parallel to the main display screen 22, and slowly retract the main display screen 22.

[0066] Example 4: Reference Fig.11 , which is the third embodiment of the present invention. This embodiment is different from the above embodiment. In the above embodiment, the two sub-display screens 23 are both in one lane, resulting in the length of the sub-display screen 23 being less than half of the length of the main display screen 22. Only when one sub-display screen 23 is set, the length of the sub-display screen 23 can be greater than half of the length of the main display screen 22.

[0067] In this embodiment, the groove 7 is divided into L-shaped groove 1 and L-shaped groove 2, and two auxiliary display screens 23 are provided. The lengths of the two auxiliary display screens 23 are the same, and the length of the auxiliary display screens 23 is smaller than the length of the main display screen 22 and larger than half of the main display screen 22; the two limiting sliding blocks 2 32 are respectively located in the L-shaped groove 1 and the L-shaped groove 2, and are used to stagger the two folded auxiliary display screens 23.

[0068] The transmission shaft 41 is provided with external threads, and the toothed plates connected to the side surfaces of each limiting sliding block 32 are meshed with the external threads on both sides of the transmission shaft 41 .

[0069] The groove 7 is divided into two grooves, namely L-shaped groove 1 and L-shaped groove 2, and the two limiting sliding blocks 32 of the two auxiliary display screens 23 are respectively located in the L-shaped groove 1 and L-shaped groove 2, so that when the auxiliary display screens 23 are folded up, the two auxiliary display screens 23 are staggered with each other and are folded up on the back of the main display screen 22.

[0070] The above structure increases the length of the secondary display screen 23 to increase the size of the display screen and enhance the visual display effect.

[0071] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
