Technical Field
[0001] This application relates to the field of display device technology, and in particular to a display screen support device and a display device. Background Technology
[0002] With the development of display technology, the application of displays is becoming increasingly widespread. Large venues, such as concert halls, large conference rooms, or competition venues, often require large displays to show images so that more viewers can see them. For this purpose, support structures are typically used to support the displays.
[0003] In related technologies, the support device typically includes a base, a vertical beam, and an inclined support. The base is rotatably connected to the vertical beam, and the inclined support is rotatably connected to the end of the vertical beam away from the base. The other end of the inclined support is engaged with the base through a slot on the base, thereby forming a triangular structure with the base, vertical beam, and inclined support. A back plate can be installed on the vertical beam, and the display screen is installed on the back plate to support the display screen.
[0004] However, in related technologies, the connection between the diagonal support and the base is prone to detachment, resulting in insufficient safety. Utility Model Content

The slot is used to engage with the engaging member. When the first limiting member rotates relative to the base until the engaging member disengages from the slot, the engaging member slides along the first sliding groove.
[0011] In one implementation, the base includes a first wall, a second wall, and a third wall. The second wall and the third wall are disposed opposite each other on both sides of the first wall along the width direction of the first wall. A first sliding groove is disposed on the second wall and the third wall. A receiving groove is provided between the second wall and the third wall, and a first limiting member is disposed in the receiving groove.
[0012] The second wall and the third wall are provided with a first rotating shaft hole, the first limiting member is provided with a second rotating shaft hole, and a rotating shaft passes through the first rotating shaft hole and the second rotating shaft hole;
[0013] The first limiting member has a seventh end and an eighth end, with a slot provided at the seventh end and a rotating shaft located between the seventh and eighth ends; a limiting arm is provided on the side of the eighth end facing the first wall, and the size of the limiting arm is greater than or equal to the width of either the second or third wall along the width direction of the second or third wall.
[0014] When the snap-fit component is engaged with the slot, there is a first distance between the end of the limiting arm facing the first wall and the first wall; the first distance is greater than the distance the snap-fit component moves from the slot.
[0015] In one implementation, the support device further includes a force-providing member, a portion of which is connected to the base and another portion of which is connected to the first limiting member; the force-providing member is used to provide a force for the seventh end to rotate toward the first wall.
[0016] In one implementation, the force-providing component includes a torsion spring having a first lever arm and a second lever arm located on the side of the rotation axis facing the eighth end; the first lever arm is connected to the base, and the second lever arm is connected to the first limiting component.
[0017] In one implementation, the first limiting member includes a fourth wall, a fifth wall, and a sixth wall. The fourth wall is disposed opposite to the first wall, and the fifth and sixth walls are disposed opposite to each other on both sides of the fourth wall along the width direction of the fourth wall; the second lever arm abuts against the fourth wall.
[0018] The fifth and sixth walls are provided with a second sliding groove, which is an arc groove. The first lever arm passes through the second sliding groove and is connected to the second and third walls.
[0019] In one implementation, a second limiting member is provided on the side of the first limiting member facing the first wall, and the second limiting member is located on the side of the rotating shaft facing the eighth end; a limiting hole is provided between the second limiting member and the first limiting member; and a second lever arm passes through the limiting hole.
[0020] In one implementation, multiple card slots are provided, and the multiple card slots are arranged at intervals along the length direction of the base on the first limiting member.
[0021] In one implementation, the side beam includes a first sub-side beam and a second sub-side beam, which are disposed opposite to each other on the vertical beam and the base.
[0022] The base is provided with multiple positioning holes, which are arranged along the length of the base. At least one of the first sub-side beam and the second sub-side beam is provided with a positioning element, which is inserted into any one of the multiple positioning holes.
[0023] In one implementation, the display screen support device further includes a cabinet frame, which is connected to the vertical beam and is located on the side of the vertical beam away from the base and the side beam. The cabinet frame is provided with a fixing position.
[0024] The second end is provided with a fixing member, which connects to the fixing position when the second end is rotated to the side of the fourth end away from the third end.
[0025] On the other hand, embodiments of this application provide a display device, including:
[0026] The support device provided in the foregoing embodiments of this application;
[0027] The display screen is mounted on the housing frame of the supporting device.
[0028] The display support device and display equipment provided in this application embodiment have a first sliding groove between the first and second ends of the base, extending along the length of the base; the third end of the vertical beam is rotatably connected to the base, and the fifth and fourth ends of the side beam are rotatably connected; a snap-fit member is provided at the sixth end of the side beam, passing through the first sliding groove and sliding along it. Thus, when folding and storing the support device, as the base rotates relative to the vertical beam, the snap-fit member can slide within the first sliding groove, allowing for simultaneous folding of both the base and the side beam. This reduces the number of steps required for folding the support device and lowers the difficulty of folding and storing it. In addition, by rotating the first limiting member on the base, at least one slot is provided on the end of the first limiting member facing the vertical beam, with the slot facing the base; thus, after the base is unfolded relative to the vertical beam, the slot can engage with the snap-fit member, thereby limiting the snap-fit member through the slot on the first limiting member, so that the position of the snap-fit member and the side beam is limited, which can prevent the snap-fit member from coming out of the slot and improve the safety of the support device for the display screen.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0046] Figure 1 This is a schematic diagram of a display screen support device provided in some embodiments of this application. Figure 2 This is an exploded structural diagram of a display screen support device provided in some embodiments of this application.
[0047] In response to the technical problems existing in the relevant technologies, refer to Figure 1 and Figure 2 As shown, some examples of embodiments of this application provide a display screen support device 10. The support device 10 may include a base 11.
[0048] In some examples, refer to Figure 2 As shown, the base 11 can be a strip structure.
[0049] In some examples, the base 11 can be a channel steel. Alternatively, the base 11 can be formed by bending at a radius.
[0050] In some examples, refer to Figure 1 and Figure 2 As shown, the base 11 may have a length direction (e.g., Figure 1 The first end 111 and the second end 112 (in the direction shown by the x-axis). It can be understood that the first end 111 and the second end 112 can be the two ends in the length direction of the base 11.
[0051] In some examples, refer to Figure 1 and Figure 2 As shown, a first groove 113 may be provided between the first end 111 and the second end 112. The first groove 113 may extend along the length direction of the base 11.
[0052] In some examples, along the width direction of the base 11 (e.g.) Figure 2 (in the direction shown by the y-axis), the first groove 113 can penetrate through the two side walls of the base 11 in the width direction.
[0053] In some examples, along the width direction of the base 11, the first groove 113 may be recessed into the two sidewalls of the base 11 in the width direction, and the first groove 113 may not penetrate the two sidewalls of the base 11 in the width direction.
[0054] In some examples, refer to Figure 1 and Figure 2 As shown, the first slide 113 may include a vertical beam 12. The vertical beam 12 may have a third end 121 and a fourth end 122. In some examples of embodiments of this application, the structure of the vertical beam 12 may be the same as, similar to or similar to that of the base 11. For details, please refer to the detailed description of the base 11 in the foregoing embodiments of this application. This application will not repeat the details in this embodiment.
[0055] In some examples, the third end 121 may be rotatably connected to the base 11. The third end 121 may also be rotatably connected to the first end 111 of the base 11.
[0056] In some examples, refer to Figure 1 and Figure 2 As shown, the third end 121 and the first end 111 may be provided with a first pin hole. A second pin may be inserted into the first pin hole. In other words, the third end 121 and the first end 111 can be rotatably connected by the second pin.
[0057] It is understood that in some examples of the embodiments of this application, the rotational connection between the third end 121 and the first end 111 is only shown as a specific example and is not intended to limit the rotational connection between the third end 121 and the first end 111.
[0058] In some examples, a pivot may be provided on one of the third end 121 and the first end 111, and a shaft hole may be provided on the other of the third end 121 and the first end 111, with the pivot passing through the shaft hole, thereby realizing the rotational connection between the third end 121 and the first end 111.
[0059] In some examples, the mating surfaces where the third end 121 and the first end 111 are rotatably connected can be provided with nylon washers. The nylon washers reduce the friction between the third end 121 and the first end 111 during rotation, facilitating rotation between them. The nylon washers can be fitted around the outer periphery of the second pin.
[0060] In some examples, refer to Figure 1 and Figure 2 As shown, the support device 10 may include a side beam 13. The side beam 13 may have a fifth end 131 and a sixth end 132 along its length. The fifth end 131 and the sixth end 132 may refer to the two opposite ends of the side beam 13 along its length.
[0061] In some examples, the fifth end 131 can be rotatably connected to the fourth end 122.
[0062] In some examples of embodiments of this application, the connection method in which the fifth end 131 and the fourth end 122 are rotatably connected can be the same as, similar to or similar to the connection method in which the third end 121 and the first end 111 are rotatably connected in the foregoing embodiments of this application. For details, please refer to the detailed description of the third end 121 and the first end 111 in the foregoing embodiments of this application. This application will not repeat the description in this embodiment.
[0063] In some examples, the sixth end 132 may be provided with a snap-fit connector 133. The snap-fit connector 133 may be provided within the first slide groove 113. The snap-fit connector 133 may be inserted into the first slide groove 113.
[0064] In some examples, the snap-fit element 133 can slide along the first slide groove 113. When the base 11 is rotated to be aligned with the direction of the vertical beam 12, the sliding stroke of the snap-fit element 133 can be the first stroke. The dimension of the first slide groove 113 along the length of the base 11 can be greater than the first stroke.
[0065] In some examples, refer to Figure 1 and Figure 2 As shown, the support device 10 may include a first limiting member 14. The limiting member can be rotatably connected to the base 11. The end of the first limiting member 14 facing the vertical beam 12 may be provided with at least one slot 141. The slot 141 faces the base 11. That is, the opening of the slot 141 faces the base 11.
[0066] In some examples, the snap-fit can be used to snap onto the snap-fit connector 133.
[0067] In some examples, when the first limiting member 14 rotates relative to the base 11 until the engaging member 133 disengages from the slot 141, the engaging member 133 slides along the first slide groove 113. For example, with Figure 1 As an example, the first limiting member 14 can move along... Figure 1 Rotate in the direction indicated by the middle arrow a. At this time, the slot 141 rotates relative to the latching member 133 along... Figure 1 Rotate in the direction indicated by arrow b, thereby causing the snap-fit 133 to disengage from the slot 141. With the snap-fit 133 disengaged from the slot 141, refer to... Figure 1 As shown, the connector 133 can be along... Figure 1 The support device 10 can be folded and stored by moving in the direction indicated by the x-axis.
[0068] The display screen support device 10 provided in this application embodiment has a first sliding groove 113 provided between the first end 111 and the second end 112 of the base 11, the first sliding groove 113 extending along the length direction of the base 11; the third end 121 of the vertical beam 12 is rotatably connected to the base 11, the fifth end 131 of the side beam 13 is rotatably connected to the fourth end 122, and a snap-fit member 133 is provided at the sixth end 132 of the side beam 13, the snap-fit member 133 passing through the first sliding groove 113 and sliding along the first sliding groove 113. Thus, when the support device 10 is folded and stored, as the base 11 rotates relative to the vertical beam 12, the snap-fit member 133 can slide within the first sliding groove 113, thereby allowing the base 11 and the side beam 13 to be folded simultaneously, reducing the number of steps required for folding the support device 10 and lowering the difficulty of folding and storing the support device 10. In addition, by rotatably connecting the first limiting member 14 to the base 11, at least one slot 141 is provided at one end of the first limiting member 14 facing the vertical beam 12, and the slot 141 faces the base 11; thus, after the base 11 is unfolded relative to the vertical beam 12, the slot 141 can engage with the snap-fit member 133, thereby limiting the snap-fit member 133 by the slot 141 on the first limiting member 14, so that the position of the snap-fit member 133 and the side beam 13 is limited, which can prevent the snap-fit member 133 from detaching from the slot 141, and can improve the safety of the support device 10 in supporting the display screen.
[0069] In some examples, refer to Figure 2 As shown, the base 11 may include a first wall 114, a second wall 115, and a third wall 116. The second wall 115 and the third wall 116 may be disposed opposite to each other in the width direction of the first wall 114 (e.g., Figure 2 The base 11 may include channel steel, as described in the foregoing embodiments of this application.
[0070] In some examples, the first groove 113 may be provided on the second wall 115 and the third wall 116. The first groove 113 may be along the length of either the second wall 115 or the third wall 116 (e.g., Figure 2 Extend in the direction shown by the x-axis.
[0071] In some examples, refer to Figure 2 As shown, a receiving groove 117 can be formed between the first wall 114 and the third wall 116. The first limiting member 14 can be provided in the receiving groove 117.
[0072] In some examples, refer to Figure 2 As shown, the second wall 115 and the third wall 116 may be provided with a first rotating shaft hole 1101. The axial direction of the first rotating shaft hole 1101 can penetrate the second wall 115 and the third wall 116 along the width direction of the first wall 114.
[0073] In some examples, the first limiting member 14 may be provided with a second rotating shaft hole 1401. A rotating shaft 1402 may pass through the first rotating shaft hole 1101 and the second rotating shaft hole 1401. In other words, the drive shaft may pass through the first rotating shaft hole 1101 on the second wall 115, the first rotating shaft hole 1101 on the first limiting member 14, and then through the first rotating shaft hole 1101 on the third wall 116, thereby making the first limiting member 14 rotatably connected to the second wall 115 and the third wall 116.
[0074] In some examples, refer to Figure 2 As shown, the first limiting member 14 may have a seventh end 142 and an eighth end 143. A slot 141 may be provided at the seventh end 142. A rotating shaft 1402 may be located between the seventh end 142 and the eighth end 143. Thus, the first limiting member 14 rotates on the base 11 with the rotating shaft 1402 as the pivot point. When the seventh end 142 rotates toward the first wall 114, the slot 141 engages with the engaging member 133. When the eighth end 143 rotates toward the first wall 114, the engaging member 133 disengages from the slot 141, facilitating the folding and storage of the support device 10.
[0075] In some examples, refer to Figure 2 The eighth end 143 may be provided with a limiting arm 144 on the side facing the first wall 114. Along the width direction of either the second wall 115 or the third wall 116 (e.g.) Figure 2 (in the direction shown by the z-axis), the size of the limiting arm 144 can be greater than or equal to the width of either the second wall 115 or the third wall 116.
[0076] In some examples, with Figure 1 As an example, in situations where the support device needs to be folded and stored, the operator can... Figure 1 Rotate the first limiting member 14 in the direction indicated by the middle arrow a, so that the eighth end 143 rotates toward the first wall 114. At this time, the seventh end 142 rotates along... Figure 1 Rotate in the direction indicated by the middle arrow b, and the snap fastener 133 disengages from the slot 141. The snap fastener 133 slides along the first slide groove 113, thereby allowing the support device 10 to be folded and stored.
[0077] In some examples, the operator can step on the eighth end 143 with their foot. While the operator is stepping on the eighth end 143, the limiting arm 144 can abut against the first wall 114, thereby limiting the rotational displacement of the eighth end 143.
[0078] In some examples, when the slot 141 and the latching member 133 are engaged, the distance between the end of the limiting arm 144 facing the first wall 114 and the first wall 114 can be greater than the distance the latching member 133 needs to move to disengage from the slot 141. That is, during the operator's rotation of the eighth point, when the limiting arm 144 abuts against the first wall 114, the latching member 133 has already disengaged from the slot 141. This facilitates the disengagement of the latching member 133 from the slot 141.
[0079] In some embodiments of this application, by providing a second wall 115 and a third wall 116 opposite to each other on both sides of the width direction of the first wall 114, a receiving groove 117 can be formed between the second wall 115 and the third wall 116, and the first limiting member 14 can be disposed in the receiving groove 117; when the support device 10 is folded and stored, the first limiting member 14 can be located in the receiving groove 117, which facilitates the folding and storage of the support device 10.
[0080] Furthermore, a first rotating shaft hole 1101 is provided on the second wall 115 and the third wall 116, and a second rotating shaft hole 1401 is provided on the first limiting member 14. A rotating shaft 1402 passes through the first rotating shaft hole 1101 and the second rotating shaft hole 1401. The rotating shaft 1402 is located between the seventh end 142 and the eighth end 143 of the first limiting member 14, and a slot 141 is provided at the seventh end 142. Thus, when it is necessary to fold and store the support device 10, the eighth end 143 can be operated to allow the latching member 133 to quickly disengage from the slot 141, making it convenient to fold and store the support device 10.
[0081] In addition, in some examples of embodiments of this application, a limiting arm 144 is provided on the side of the eighth end 143 facing the first wall 114, and the size of the limiting arm 144 is greater than or equal to the width of either the second wall 115 or the third wall 116 along the width direction. Furthermore, when the snap-fit member 133 is engaged with the slot 141, there is a first distance between the end of the limiting arm 144 facing the first wall 114 and the first wall 114; the first distance is greater than the movement distance of the snap-fit member 133 disengaging from the slot 141. Thus, the movement of the eighth end 143 can be limited by the limiting arm 144, facilitating the determination of the timing for folding the inclined beam when operating the folding and storage support device 10 on the eighth end 143. This improves the efficiency of folding and storing the support device 10.
[0082] Figure 3 yes Figure 2 A magnified view of a portion of point A in the middle.
[0083] In some examples, refer to Figure 2 and Figure 3 As shown, the support device 10 may include a force-providing member 15. A portion of the force-providing member 15 may be connected to the base 11. Another portion of the force-providing member 15 may be connected to the first limiting member 14. The force-providing member 15 can be used to provide a force for the seventh end 142 to rotate toward the first wall 114.
[0084] In some examples, the force-providing element 15 may include a magnetic element. For example, a magnet may be provided at the seventh end 142, and the magnet generates a force with the first wall 114 through magnetic attraction, pulling the seventh end 142 toward the first wall 114. Alternatively, magnets may be provided on both the seventh end 142 and the first wall 114, with the two magnets on the seventh end 142 and the first wall 114 having opposite poles, thereby pulling the seventh end 142 toward the first wall 114 through magnetic attraction. Alternatively, magnets may be provided on the eighth end 143 and the first wall 114, with the two magnets on the eighth end 143 and the first wall 114 having like poles; thereby pushing the seventh end 142 toward the first wall 114 through the repulsive force between the two magnets.
[0085] In some examples of embodiments of this application, a force-providing member 15 is provided, with one part of the force-providing member 15 connected to the base 11 and the other part connected to the first limiting member 14. In this way, the force-providing member 15 can provide a force to the seventh end 142 to rotate towards the first wall 114. This ensures that the seventh end 142 always has a tendency to rotate towards the first wall 114 during the process of the support device 10 supporting the display screen, ensuring the effectiveness of the slot 141 in limiting the locking member 133 and improving the safety of the support device 10.
[0086] In some examples, refer to Figure 2 and Figure 3 As shown, the force-providing component 15 may include a torsion spring. (Refer to...) Figure 3 As shown, the torsion spring may have a first lever arm 151 and a second lever arm 152. The first lever arm 151 and the second lever arm 152 may be located on the side of the rotation shaft 1402 facing the eighth end 143. The first lever arm 151 may be connected to the base 11, and the second lever arm 152 may be connected to the first limiting member 14.
[0087] The torsion spring can provide a force to the eighth end 143 away from the first wall 114, thereby causing the seventh end 142 to rotate toward the first wall 114.
[0088] In some examples of embodiments of this application, a torsion spring is provided, with its first arm 151 and second arm 152 positioned on the side of the rotation shaft 1402 facing the eighth end 143. The first arm 151 is connected to the base 11, and the second arm 152 is connected to the first limiting member 14. Thus, the force exerted by the torsion spring on the eighth end 143 ensures that the seventh end 142 always tends to rotate towards the first wall 114. This ensures the effective limiting of the first limiting member 14 on the snap-fit member 133, improving the safety of the support device 10.
[0089] In some examples, the force-providing element 15 may include a tension spring. The tension spring may be connected between the seventh end 142 and the first wall 114. The tension spring may provide a tension force on the seventh end 142 toward the first wall 114, such that the seventh end 142 always has a tendency to rotate toward the first wall 114.
[0090] In some examples, refer to Figure 2 As shown, the first limiting member 14 may include a fourth wall 145, a fifth wall 146, and a sixth wall 147. The fourth wall 145 may be opposite to the first wall 114. The fifth wall 146 and the sixth wall 147 may be along the width direction of the fourth wall 145 (e.g., Figure 2 The first limiting member 14 is positioned on both sides of the fourth wall 145, with the direction indicated by the y-axis. It can be understood that the structure of the first limiting member 14 can be the same as, similar to or similar to the structure of the base 11. For details, please refer to the detailed description of the base 11 in the foregoing embodiments of this application. This application will not repeat the description further.
[0091] In some examples, the second lever arm 152 can abut against the fourth wall 145.

The second sliding groove 1403 may be an arc-shaped groove. The center of the second sliding groove 1403 may be the axis of the rotating shaft 1402. The first lever arm 151 may pass through the second sliding groove 1403 and be connected to the second wall 115 and the third wall 116.
[0093] In some examples, there may be two first lever arms 151. One first lever arm 151 is connected to the second wall 115. The other first lever arm 151 is connected to the third wall 116.
[0094] In some examples of embodiments of this application, a fifth wall 146 and a sixth wall 147 are provided on both sides of the fourth wall 145 in the width direction, and the second lever arm 152 abuts against the fourth wall 145. A second sliding groove 1403, which is an arc-shaped groove, is provided on the fifth wall 146 and the sixth wall 147. The first lever arm 151 passes through the second sliding groove 1403 and connects with the second wall 115 and the third wall 116. Thus, when operating the eighth end 143, the first lever arm 151 can slide within the second sliding groove 1403, facilitating the rotation of the limiting member around the rotation axis 1402 and facilitating the connection of the first lever arm 151 with the second wall 115 and the third wall 116, thereby providing force to the first limiting member 14 and facilitating the setting of the force providing member 15.
