Description

Technical Field

[0001] This application relates to display devices, and more specifically to a display screen bracket and display device. Background Technology

[0002] A monitor is a display device used to display various information such as text, images, and videos. Some portable monitors can be connected to laptops or tablets for multi-screen viewing, meeting the needs of different occasions. Some portable monitors also come with foldable stands to prop up the monitor or raise it to a suitable height for easy viewing. According to the inventors, these monitor stands have a support base and a support rod, with the support rod hinged to the base. The friction at the hinge determines the weight the monitor can support. When the monitor is heavy, such as a dual-screen or triple-screen monitor, the friction at the hinge may not be sufficient to stably support it, and the support rod may fail to maintain support due to the monitor's weight. Utility Model Content

[0003] The purpose of this application is to provide a display screen bracket and display device to improve the support strength of the bracket.

[0004] To achieve the above objectives, this application provides a display screen bracket, which includes a base, at least one support rod, at least one positioning part, at least one auxiliary rod, and at least one elastic element. One end of the support rod is hinged to the base, and the other end is hinged to the display screen. The positioning part is disposed on the support rod and faces the base. The auxiliary rod is located between the support rod and the base, with its outer end fixed to the positioning part and its inner end hinged to the base. The elastic element connects the auxiliary rod and the base respectively, and the elastic force of the elastic element is used to drive the auxiliary rod to rotate toward the support rod when the support rod is rotated open relative to the base.

[0005] Another aspect of this application provides a different display screen bracket, which includes a base, at least one support rod, at least one positioning part, at least one auxiliary rod, and at least one elastic element. One end of the support rod is hinged to the base, and the other end is hinged to the display screen. The positioning part is disposed on the base and faces the support rod. The auxiliary rod is located between the support rod and the base, with its outer end fixed to the positioning part and its inner end hinged to the support rod. The elastic element connects the auxiliary rod and the support rod respectively, and the elastic force of the elastic element is used to drive the auxiliary rod to rotate toward the base when the support rod is rotated open relative to the base.

[0006] In another aspect, this application also provides a display device, which includes a first display screen and a display screen bracket of one of the above aspects, wherein the first display screen is hinged to a support rod.

[0007] The technical solution of this application uses an auxiliary rod to connect the support rod and the base respectively. The auxiliary rod, support rod and base form a triangular structure, which improves the support force of the display bracket and makes the support structure relatively stable. When the support rod rotates open relative to the base, the elastic element drives the auxiliary rod to rotate automatically toward the support rod. That is, the auxiliary rod will open synchronously with the support rod, which avoids the support rod not being able to obtain sufficient support force in time if the auxiliary rod does not open, thus improving the reliability of the display bracket.

[0008] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this application more obvious and understandable, some embodiments are listed below and described in detail.

[0030] At least one embodiment of this application is a display screen bracket. For example... Figures 1 to 3 As shown, the display screen bracket includes a base 10, at least one support rod 20, at least one positioning part 21, at least one auxiliary rod 22, and at least one elastic element 24. Figure 1As shown, there are two support rods 20. One end of each support rod 20 is hinged to the base 10, and the other end is hinged to the display screen 101. The display screen 101 is located between the two support rods 20. Several positioning parts 21 are provided on the support rods 20 and face the base 10. An auxiliary rod 22 is located between the support rods 20 and the base 10. There are two auxiliary rods 22, each corresponding to one of the support rods 20. The outer end of the auxiliary rod 22 is fixed to the positioning part 21, and the inner end 222 of the auxiliary rod 22 is hinged to the base 10. Inserting the outer end 221 of the auxiliary rod 22 into the positioning part 21 at different positions allows the support rods 20 to be fixed at different angles, thus achieving adjustable height of the display screen 101. There are also two elastic elements 24, each corresponding to one of the auxiliary rods 22. The elastic element 24 connects the auxiliary rod 22 and the base 10 respectively. The elastic force of the elastic element 24 is used to drive the auxiliary rod 22 to rotate toward the support rod 20 when the support rod 20 rotates open relative to the base 10. Thus, the display bracket connects the support rod 20 and the base 10 respectively via the auxiliary rod 22. The auxiliary rod 22, support rod 20, and base 10 form a triangular structure, which enhances the support force of the display bracket and makes the support structure relatively stable. When the support rod 20 rotates open relative to the base 10, the elastic element 24 drives the auxiliary rod 22 to automatically rotate toward the support rod 20. That is, the auxiliary rod 22 opens synchronously with the support rod 20, preventing the support rod 20 from not receiving sufficient support force in time if the auxiliary rod 22 does not open, thereby improving the reliability of the display bracket.

[0031] In other embodiments, a single support rod is provided, which is hinged to the lower center of the display screen. Depending on the required support force, one or more auxiliary rods may be used. Depending on the required rotational force, one or more elastic elements may be present.

[0032] In some embodiments, such as Figure 1 As shown, the elastic element 24 is a torsion spring made of spring steel. The two legs 241 of the elastic element 24 abut against the auxiliary rod 22 and the base 10, respectively. The restoring force of the elastic element 24 is used to push the auxiliary rod 22 to rotate upwards. The auxiliary rod 22 and the base 10 are hinged via a pivot 23, which passes through the elastic element 24, preventing it from dislodging. The torque of the elastic element 24 allows the auxiliary rod 22 to rotate and open with the support rod 20, and also presses the outer end of the auxiliary rod 22 tightly into the positioning part 21, preventing the auxiliary rod 22 from easily dislodging from the positioning part 21 and thus maintaining the stability of the display screen bracket. Figure 1 The torsion spring 24 shown is a standard torsion spring. In other embodiments, the torsion spring 24 is a double torsion spring to provide greater torque and more stable restoring force.

[0033] In at least one other embodiment, such as Figure 2As shown, the elastic element 24 is a tension spring made of spring steel. One end of the elastic element 24 is connected between the inner end 222 and the outer end 221 of the auxiliary rod 22, and the other end is fixed between the hinge 202 of the support rod 20 and the base 10 and the inner end 222 of the auxiliary rod 22. When the support rod 20 rotates upward, the tension of the elastic element 24 drives the auxiliary rod 22 to rotate in direction A. The tension of the elastic element 24 can also press the outer end 221 of the auxiliary rod 22 tightly into the positioning part 21, so that the auxiliary rod 22 will not easily detach from the positioning part 21, which helps to maintain the stability of the display screen bracket.

[0034] In some embodiments, such as Figure 2 As shown, there is more than one positioning part 21. Each positioning part 21 includes a first side surface 211 near the hinge point 202 of the support rod 20 and a second side surface 212 away from the hinge point 202 of the support rod 20. In the direction from the hinge point 202 of the support rod 20 towards the outer end 203 of the support rod 20, the angle between the first side surface 211 and the second side surface 212 remains constant. The cross-sectional length of the first side surface 211 gradually increases, increasing the contact area between the positioning part 21 and the outer end 221 of the auxiliary rod 22, thus improving support stability. Figure 2 The positioning part 21 shown is a groove with a first side surface 211 and a second side surface 212. The outer end 221 of the auxiliary rod 22 can be inserted into the positioning part 21 for fixation. In other embodiments, the positioning part can be a groove or hole of other shapes for the auxiliary rod to be inserted and fixed. Alternatively, in other embodiments, the positioning part is a protruding positioning post with a positioning hole at the outer end of the auxiliary rod, and the positioning post passes through the positioning hole for fixation.

[0035] In some embodiments, such as Figure 1 As shown, the base 10 has a strip groove 121 corresponding to the support rod 20, and one end of the support rod 20 is inserted into the strip groove 121 to form a hinge. When the support rod 20 is folded into the base 10, both the auxiliary rod 22 and the support rod 20 are placed in the strip groove 121, which reduces the volume of the entire display screen bracket after folding, making it easier to store, and also improves the overall integrity of the display screen bracket.

[0036] In some embodiments, such as Figure 1 As shown, the side walls of the two strip grooves 121 are respectively provided with clearance positions 122. When the support rod 20 is folded into the base 10, the central shaft 201 of the support rod 20, which is used to hinge with the display screen 101, is placed in the two clearance positions 122, so that the support rod 20 can be folded into the strip groove 121 as a whole, reducing the volume of the entire display screen bracket after folding. In addition, as Figure 1 As shown, the strip groove 121 near the elastic member 24 is used to position the straight groove 123 of the support leg 241 of the elastic member 24, while the auxiliary rod 22 near the elastic member 24 is provided with a U-shaped groove 223 corresponding to the placement of the support leg 241 of the elastic member 24.

[0037] When the support rod 20 is folded into the base 10, it is placed in the slot 121. At this time, the support rod 20 needs to be fixed in the slot 121 to prevent it from rotating open on its own. Fixing the support rod 20 in the slot 121 can be achieved through snap-fit, magnetic attraction, or other methods. In at least one embodiment, such as... Figure 15 As shown, a first magnetic element 124 is provided inside the strip groove 121, and a second magnetic element 204 corresponding to the first magnetic element 124 is provided on the support rod 20. When the support rod 20 is placed in the strip groove 121, the magnetic attraction between the first magnetic element 124 and the second magnetic element 204 fixes the support rod 20 in the strip groove 121, allowing it to remain in a folded and stored state and preventing it from easily detaching from the strip groove 121, thus improving ease of use. Specifically, the first magnetic element 124 is a magnet, and the second magnetic element 204 is an iron block, or the first magnetic element 124 is an iron block, and the second magnetic element 204 is a magnet, or both the first magnetic element 124 and the second magnetic element 204 are magnets, but their mating surfaces have different polarities. Figure 15 The illustration only shows a magnetic element at the outer end 203 of the support rod 20 for magnetic fixation. In other embodiments, magnetic elements can be installed at other locations on the support rod 20 for magnetic fixation, such as near the hinge of the support rod 20. In other embodiments, there are more than one first magnetic element and more than one second magnetic element. It should be noted that the magnet in the strip groove 121 should avoid the auxiliary rod 22 to prevent the magnetic attraction force of the magnet from preventing the elastic element 24 from driving the auxiliary rod 22 to rotate and open synchronously with the support rod.

[0038] In at least one embodiment, when the support rod 20 is placed in the strip groove 121, the support rod 20 is engaged and fixed with the strip groove 121. For example... Figure 15 As shown, the inner wall of the strip groove 121 is provided with a protrusion 125, and the support rod 20 is provided with a corresponding recess 205. When the support rod 20 is placed in the strip groove 121, the protrusion 125 is placed in the recess 205 to form a snap-fit, and the support rod 20 is fixed. In at least one other embodiment, such as Figure 15 As shown, the clearance position 122 of the strip groove 121 is provided with an elastic clip 126. When the support rod 20 is placed in the strip groove 121, the central shaft 201 of the support rod 20 for hinge with the display screen 101 is inserted into the elastic clip 126 and forms a snap-fit ​​fixation, so that the support rod 20 is fixed in the strip groove 121.

[0039] In some embodiments, such as Figure 1As shown, the base 10 includes a central rod 11 and two side rods 12. The two side rods 12 are vertically connected to both ends of the central rod 11, and the side rods 12 are fixedly connected to both ends of the central rod 11. Each side rod 12 corresponds to a support rod 20, and each strip groove 121 corresponds to a side rod 12. The strip groove 121 is located on the side rod and extends along the length of the side rod 12. The structure of the base 10 reduces its own volume, leaving more space for placing the folded support rod 20, display screen 101, etc., which helps to reduce the overall volume of the folded product. Figure 1 As shown, the two support rods 20 are used to hinge the lower sides of the same display screen 101. When the support rods 20 are folded into the base 10, the display screen 101 can be stored in the position between the two side rods 12. After folding, the overall thickness of the product is reduced, that is, the product is thinner after folding, making it easier to store.

[0040] In some embodiments, such as Figure 1 As shown, a handle groove 111 is provided in the middle of the central rod 11. When the support rod 20 is folded into the base 10, the display screen 101 can be stored between the two side rods 12. At this time, the entire product can be lifted by holding the handle groove 111. The handle groove 111 helps to improve the carrying experience of the product.

[0041] At least one embodiment is a display screen bracket, the structure of which is as follows: Figure 3 As shown, the display screen bracket includes a base 10, at least one support rod 20, at least one positioning part 21, at least one auxiliary rod 22, and at least one elastic member 24. One end of the support rod 20 is hinged to the base 10, and the other end is hinged to the display screen (not shown). The positioning part 21 is disposed on the base 10 and faces the support rod 20. The auxiliary rod 22 is located between the support rod 20 and the base 10. The auxiliary rod 22 corresponds to the support rod 20 one-to-one, with the outer end 221 of the auxiliary rod 22 inserted into the positioning part 21, and the inner end 222 of the auxiliary rod 22 hinged to the support rod 20. The elastic member 24 connects the auxiliary rod 22 and the support rod 20 respectively. The elastic force of the elastic member 24 is used to drive the auxiliary rod 22 to rotate toward the base 10 when the support rod 20 is rotated open relative to the base 10. Figure 3 The elastic element 24 is a torsion spring, and its two legs 241 abut against the auxiliary rod 22 and the support rod 20, respectively. The restoring force of the elastic element 24 is used to push the auxiliary rod 22 to rotate downward along direction B.

[0042] At least one embodiment is a display screen bracket, the structure of which is as follows: Figure 1As shown. The display screen bracket includes a base 10, at least one support rod 20, at least one positioning part 21, and at least one auxiliary rod 22. One end of the support rod 20 is hinged to the base 10, and the other end is hinged to the display screen 101. The positioning part 21 is provided on the support rod 20 and faces the base 10. The auxiliary rod 22 is located between the support rod 20 and the base 10. The outer end 221 of the auxiliary rod 22 is inserted into the positioning part 21, and the inner end of the auxiliary rod 22 is hinged to the base 10. The base 10 has a strip groove 121 corresponding to the support rod 20, and the support rod 20 is inserted into the strip groove 121 to form a hinge. When the support rod 20 is folded into the base 10, both the auxiliary rod 22 and the support rod 20 are placed in the strip groove 121. In this embodiment, the display screen bracket does not use an elastic element to push the auxiliary rod to rotate. Therefore, when the support rod 20 is rotated upward to open, the auxiliary rod 22 needs to be manually pulled up so that the auxiliary rod 22 can be inserted into the positioning part 21 of the support rod 20 to support the support rod. In this embodiment, after the support rod 20 is folded up, the support rod 20 and the auxiliary rod 22 are placed in the strip groove 121 of the base 10, which reduces the volume of the entire display screen bracket after folding up, making it easier to store, and the overall integrity of the display screen bracket is better.

[0043] At least one embodiment is a display screen bracket, the structure of which is as follows: Figure 3 As shown. The display screen bracket includes a base 10, at least one support rod 20, at least one positioning part 21, and at least one auxiliary rod 22. One end of the support rod 20 is hinged to the base 10, and the other end is hinged to the display screen 101. The positioning part 21 is located on the base 10 and faces the support rod 20. The auxiliary rod 22 is located between the support rod 20 and the base 10, with its outer end 221 inserted into the positioning part 21 and its inner end hinged to the support rod 20. The base 10 has a strip groove 121 corresponding to the support rod 20, and the support rod 20 is inserted into the strip groove 121 to form a hinge. When the support rod 20 is folded into the base 10, both the auxiliary rod 22 and the support rod 20 are placed in the strip groove 121. In this embodiment, the display stand does not use an elastic element to push the auxiliary rod 22 to rotate. Therefore, when the support rod 20 rotates upward to open, the auxiliary rod 22 opens downward under the action of gravity. The position of the auxiliary rod 22 inserted into the positioning part 21 of the base 10 can be manually adjusted to support the support rod 20. After the support rod 20 is folded up, the support rod 20 and the auxiliary rod 22 are placed in the strip groove 121 of the base 10, which reduces the volume of the entire display stand after folding, making it easier to store, and the overall integrity of the display stand is better.

[0044] At least one embodiment of this application is a display device, the structure of which is as follows: Figure 4 As shown, the display device includes a first display screen 31 and a display screen bracket 100 according to at least one embodiment of the present application. The lower two sides of the first display screen 31 are respectively hinged to two support rods 20, and the first display screen 31 is located between the two support rods 20.

[0045] In some embodiments, such as Figure 5 As shown, the display device includes a first display screen 31, a second display screen 32, and a display screen bracket 100 according to at least one embodiment of this application. The second display screen 32 is rotatably connected to one side of the first display screen 31 via a first dual-axis hinge 40. When folding is required, the second display screen 32 needs to be folded in front of the first display screen 31. The width of the first display screen 31 and the second display screen 32 after folding will not exceed the distance between the two side bars 12 of the base 10, so as to avoid the second display screen 32 from touching the support rod 20 or the base 10 and causing scratches, and also to reduce the product volume after folding.

[0046] In some embodiments, such as Figure 6 As shown, the display device includes a first display screen 31, a second display screen 32, a third display screen 33, and a display screen bracket 100 according to at least one embodiment of this application. The second display screen 32 is rotatably connected to one side of the first display screen 31 via a first dual-axis hinge 40, and the third display screen 33 is rotatably connected to the other side of the first display screen 31 via a second dual-axis hinge 50. When folding is required, the second display screen 32 must first be folded in front of the first display screen 31, and then the third display screen 33 is rotated forward and folded behind the second display screen 32. This folding structure can shield and protect the screens of the first display screen 31, the second display screen 32, and the third display screen 33 in the stored state, avoiding scratches or bumps to the screens during storage. The width of the first display screen 31, the second display screen 32, and the third display screen 33 after folding will not exceed the distance between the two side bars 12 of the base 10, so as to avoid the second display screen 32 and the third display screen 33 touching the support rod 20 or the base and causing scratches, and also reducing the product volume after folding.

[0047] In some embodiments, such as Figure 7As shown, the first dual-axis hinge 40 has two parallel pivots 401, and the distance between the two pivots 401 is a first width D1. The second dual-axis hinge 50 has two parallel pivots, and the distance between the two pivots 501 is a second width D2. The first width D1 is smaller than the second width D2, and the difference between the two is not less than the thickness of the second display screen 32. As described above, when folding is required, the second display screen 32 is first folded in front of the first display screen 31, and then the third display screen 33 is folded behind the second display screen 32. The first width D1 is smaller than the second width D2, and the difference between the two is not less than the thickness of the second display screen 32, which allows the third display screen 33 to overlap the back of the second display screen 32, and at this time, the end of the third display screen 33 away from the second dual-axis hinge 50 will not stick up, thereby improving the overall effect after folding. In at least one other embodiment, the first width D1 is smaller than the second width D2 and the difference between the two is equal to the thickness of the second display screen 32. When the third display screen 33 is stacked on the back of the second display screen 32, the third display screen 33 can be completely attached to the back of the second display screen 32, and the overall effect after folding is better.

[0048] Furthermore, in at least one other embodiment, a third magnetic element (not shown) is provided inside the third display screen, and a fourth magnetic element (not shown) is provided on the inner side of the back of the second display screen. When the third display screen is folded and folded onto the back of the second display screen, the third and fourth magnetic elements are positioned close to each other, generating a magnetic attraction between them to fix the third display screen to the back of the second display screen, thus maintaining the folded state of the product. Specifically, the third magnetic element is a magnet, and the fourth magnetic element is an iron block, or the third magnetic element is an iron block and the fourth magnetic element is a magnet.

[0049] In some embodiments, such as Figure 8 As shown, the first display screen 31 includes at least a front shell 313, a back shell 311, and a display unit 312. The front shell 313 is glued to the back shell 311 and fixes the display unit 312 therein. The back shell 311 needs to be connected to the second display screen 32, the third display screen 33, and the support rod 20. Figure 6 The back cover 311 is made of aluminum alloy to ensure sufficient support strength. In at least one other embodiment, the back cover 311 is made of plastic, and its thickness needs to be sufficient to provide adequate strength. Similarly, the back cover 321 of the second display screen 32 and the back cover 331 of the third display screen 33 can both be made of aluminum alloy or plastic.

[0050] In some embodiments, such as Figure 8 As shown, the first display screen 31 and the support rod 20 ( Figure 6The hinge is achieved through hinge shaft 62. A hinge seat 60 is fixed inside the first display screen 31. The inner end of the hinge shaft 62 is placed in the hinge seat 60 and fixedly connected. The outer end of the hinge shaft 62 passes through the support rod 20. Figure 6 Specifically, a connecting plate 621 is fixed to the inner end of the hinge shaft 62. The connecting plate 621 is inserted into the groove 61 of the hinge seat 60 for positioning and is fixedly connected by screws. The outer end of the hinge shaft 62 protrudes from the hinge seat 60.
