Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a combined display screen module, including: a protection bin 1, screens 3 are symmetrically arranged on both sides of the protection bin 1, a storage groove 9 is arranged on the side wall of the protection bin 1, and a protection component is included and stored inside the storage groove 9. The protection component is located between the two screens 3 and has two states of expansion and folding. In the expanded state, the protection component will form a U-shaped isolation frame between the two screens 3. In the folded state, the protection component will be folded and stored inside the storage groove 9; in order to solve the inconvenience during the transportation of the screen 3 and the possible damage to the screen 3, the protection component is used for transportation or protection of the screen surface when not in use. When the screen 3 is folded, the protection component will be opened simultaneously. The opening of the protection component is in contact with the screen 3 surface for protection; a driving component, the driving component can control the expansion and folding of the protection component; in order to realize that the protection component can be automatically opened during the opening process of the screen 3, the driving component arranged inside the protection bin 1 is used to control the expansion and folding of the protection component, which is convenient for personnel operation and more convenient to use.

[0031] In a more preferred embodiment, a sliding sleeve 5 is arranged on the side of the screen 3. Rotating blocks 7 are rotatably installed at both ends of the protection bin 1. The rotating blocks 7 are slidably connected to the sliding sleeve 5. Rotating columns 23 are symmetrically installed at both ends in the storage groove 9. When the rotating blocks 7 on both sides are folded and rotated, the screen 3 forms a folded state. When the rotating blocks 7 on both sides are unfolded and rotated, the two screens 3 are unfolded. When the rotating blocks 7 are pushed to slide in the sliding sleeve 5 to a certain position, the sides of the two screens 3 come into contact to achieve seamless splicing; the two screens are folded and docked. When folding, the rotating blocks 7 will drive the driving assembly to rotate the rotating columns 23, so as to expand and open the protection assembly; through the limit of the rotating blocks 7 and the sliding sleeve 5, it can always remain in a plane when the two display screens are spliced, and there will be no height difference when the two screens 3 come into contact, achieving a better splicing effect.

[0032] The following provides two implementation schemes of the protection assembly.

[0033] Embodiment 1:

[0034] Please refer to Figure 2-Figure 7 , the protection assembly includes relative rotating rods 2. One end of the relative rotating rods 2 is connected to the rotating columns 23. A driven rod 30 is fitted to the end of the relative rotating rods 2 away from the storage groove 9. A connecting seat 32 is arranged between the driven rod 30 and the relative rotating rods 2. A protection cross bar 31 is fitted to the end of the driven rod 30 away from the relative rotating rods 2. The protection cross bar 31 and the driven rod 30 are connected through the connecting seat 32. A limiting rod 33 is arranged through the side of the connecting seat 32. When the screen 3 is folded, the rotating columns 23 drive the relative rotating rods 2 to rotate. At the same time, the driven rod 30 and the protection cross bar 31 are opened to form a U-shaped isolation frame, which can contact the frame of the screen 3 to protect the screen; when the screen 3 is in a folded state, the rotating blocks 7 drive the driving assembly to rotate the rotating columns 23. When the rotating columns 23 rotate, the relative rotating rods 2 rotate to drive the driven rod 30 to unfold. When the relative rotating rods 2 are opened to a preset position, the relative rotating rods 2, the driven rod 30 and the protection cross bar 31 will form a U-shaped frame, which will contact and support the folded frame of the screen 3 at this time.

[0035] On the basis of Embodiment 1, protective pads 34 are arranged on the contact surfaces of both sides of the relative rotating rods 2, the driven rod 30, the protection cross bar 31 and the connecting seat 32 with the screen. The protective pads 34 contact the surface of the folded screen 3. A corrugated structure is arranged on the side of the protective pads 34 contacting the screen 3, which can increase its surface area and improve the sealing effect; the corrugated structure arranged on the protective pads 34 will make it fit more tightly when contacting the screen, form a sealed space while fitting and protecting the surface of the screen 3, so that external dust will not enter the surface of the folded screen 3, thus keeping the surface of the screen 3 clean.

[0036] Embodiment 2:

[0037] Please refer to Figure 8-Figure 10 , the protection component includes a protection rod 4. One end of the protection rod 4 is connected to the rotating column 23. First protection short rods 11 and second protection short rods 12 are respectively rotatably arranged at the ends of the two protection rods 4 away from the storage groove 9. One ends of the first protection short rod 11 and the second protection short rod 12 are slidably connected and can be retracted into the storage groove 9 together with the protection rod 4. When the screen 3 is folded, the rotating column 23 drives the protection rod 4 to rotate, and at the same time drives the first protection short rod 11 and the second protection short rod 12 to unfold to form a U-shaped isolation frame, which can contact the frame of the screen 3 to protect the screen; when the screen 3 is in the folded state, the rotating block 7 drives the driving component to rotate the rotating column 23. When the rotating column 23 rotates, the protection rod 4 rotates to drive the first protection short rod 11 and the second protection short rod 12 to unfold. When the protection rod 4 rotates to a preset position, it stretches with the first protection short rod 11 and the second protection short rod 12 to form a U-shaped frame, and at this time it will contact the folded frame of the screen 3 to form support and protection.

[0038] On the basis of Embodiment 2, protection airbags 27 are arranged on the protection rod 4, the first protection short rod 11 and the second protection short rod 12. All the protection airbags 27 are interconnected. An inflation hole is arranged on the side of the protection airbag 27. When the screen 3 is folded to form a U-shaped isolation frame, at this time, the protection airbag 27 is inflated through the inflation hole. At this time, the folded screen 3 contacts the protection airbag 27 to achieve the functions of protection, shock absorption and buffering; when the protection rod 4, the first protection short rod 11 and the second protection short rod 12 form a U-shaped frame to protect and support the frame of the screen 3, the inflation hole on the side of the protection airbag 27 is opened for inflation. When the protection airbag 27 is full, it will contact the surface of the screen 3 at this time. At this time, it can better support the folded screen 3 and provide better protection, and also achieve the functions of shock absorption and buffering during transportation.

[0039] In a more preferred embodiment, a protection frame 8 is arranged on the back of the screen 3. Filter holes 17 are arranged on the side wall of the protection frame 8. A hole-blocking plate 15 is arranged inside the protection frame 8. When the screen 3 is folded, the hole-blocking plate 15 can block the filter holes 17. A graphene heat-conducting sheet 25 is arranged between the screen 3 and the sliding sleeve 5. When the screen 3 is in use, the hole-blocking plate 15 will move down to open the filter holes 17 for heat dissipation; the protection frame 8 of the screen 3 is integrally wrapped on the surface of the display module, which will cause the electronic components to be prone to overheating inside the protection frame 8 and cause damage. At the same time, some displays will have dust entering through the heat dissipation holes. To solve the above problems, a graphene heat-conducting sheet 25 is arranged on the back of the screen 3 to absorb heat, and at the same time, filter holes 17 are opened to dissipate the internal heat. A filter is arranged on the filter holes 17 to prevent dust from entering. At the same time, the hole-blocking plate 15 will only open the filter holes 17 when the screen 3 is opened, and will block the filter holes 17 when folded to prevent dust from entering when not in use;

[0040] Furthermore, the nickel-titanium alloy push block 18 is an alloy material composed of nickel and titanium. This alloy usually has special shape memory properties. The nickel-titanium alloy has the characteristic of memory shape, and can restore its original shape by heating or other means after being deformed by external force; the nickel-titanium alloy push block 18 is arranged inside the sliding sleeve 5 according to its characteristics. When the screen 3 is opened, the rotating block 7 will push the nickel-titanium alloy push block 18 to contact the baffle plate 15 and move the baffle plate 15 downward a certain distance. When the temperature of the graphene thermal conductive sheet 25 increases, it will continue to extend and push the baffle plate 15 downward, so that the filter hole 17 is opened, the number of holes is increasing, and the heat dissipation effect is increased. The number of heat dissipation holes can be automatically adjusted according to the temperature conditions inside the display module to achieve effective heat dissipation.

[0041] Furthermore, an elastic member 14 is provided at the lower end of the hole-blocking plate 15 and the back side of the screen 3, and an inclined slider 16 is provided at the upper end of the hole-blocking plate 15. A nickel-titanium alloy push block 18 is also provided at one end of the sliding sleeve 5. The inclined slider 16 contacts one end of the nickel-titanium alloy push block 18. The elastic member 14 will drive the hole-blocking plate 15 to rise when the screen 3 is folded to block the filter holes 17, and at the same time push the nickel-titanium alloy push block 18 back into the sliding sleeve 5; the upper end of the inclined slider 16 is provided with an inclined surface to contact one end of the nickel-titanium alloy push block 18. When the temperature of the nickel-titanium alloy push block 18 rises due to heat, the inclined slider 16 is continuously pressed downward, and at this time, the hole-blocking plate 15 will continuously open the filter holes 17 to increase the number of holes for heat dissipation; when the screen 3 is folded, the hole-blocking plate 15 will be moved upward by the elastic potential energy released by the elastic member 14, and the filter holes 17 will be blocked to prevent dust from entering, wherein the elastic member can be a tower spring or a coil spring.

[0042] Furthermore, the filter hole 17 includes a connecting rod 29 arranged on the outer surface, and a scraper 26 matching the filter hole 17 is arranged on the connecting rod 29. The end of the connecting rod 29 close to the protective bin 1 is provided with a top block 28, and the lower end of the top block 28 is provided with a spring 24. When the screen 3 is unfolded and used, the spring 24 is in a compressed state. When the screen 3 is in a folded state, the spring 24 is in a rebound state and drives the connecting rod 29 to move so that the scraper 26 scrapes the dust on the surface of the filter hole 17. In order to avoid damage to the screen 3 caused by dust, the heat dissipation holes of the display screen are kept clean to prevent dust from clogging. Now when the scraper 26 is used and the screen 3 is folded, the spring 24 will release potential energy to push out the top block 28, drive the connecting rod 29 to move and make the scraper 26 slide in the filter hole 17 to scrape off the dust on the surface of the filter hole 17, and when the scraper 26 slides, the hole-blocking plate 15 will rise to block the filter hole 17 to prevent dust from entering the inside of the screen 3 during the scraping process.

[0043] Furthermore, a double gear rod 22 is installed inside the cavity 19, one end of the double gear rod 22 is meshed with a gear 20, and the other end is meshed with a rotating column 23, the gear 20 is meshed with the bottom of the rotating block 7, and the rotating column 23 is connected to the relative rotating rod 2 and the screen protection rod 4. When the rotating block 7 rotates, the gear 20 is driven to rotate and drive the double gear rod 22 to make the rotating column 23 open the protection rod 4 and the relative rotating rod 2; the double gear rod 22 is set as a connecting rod with gears at both ends, and the end meshed with the gear 20 can be meshed with the gear 20 The gear at the other end close to the rotating column 23 is meshed, and a bevel gear is set as a bevel gear. At the same time, the upper end of the rotating column 23 is also provided with a bevel gear meshing with the bevel gear at one end of the rotating column 23. When the rotating block 7 rotates to fold the screen 3, the gear 20 rotates to drive the gear at one end of the double gear rod 22 to rotate the double gear rod 22. When the double gear rod 22 rotates, the bevel gear at the other end drives the rotating column 23 to open the protective rod 4 and the relative rotating rod 2. The opening of the protective rod 4 and the relative rotating rod 2 will form a protective frame to protect the frame of the folded screen 3.

[0044] The present invention utilizes the above structure to solve the problem of protecting the screen of the combined display screen by the protective component during the transportation or storage of the display screen, thereby preventing the display screen from being damaged and ensuring the surface cleanliness.
