Description

Technical Field

[0001] This utility model relates to the field of display device technology, and more specifically, to a support device and a display device. Background Technology

[0002] With the development of science and technology, display devices are being used in daily life and work. To improve user experience, display devices are usually mounted on support devices with hovering functions. However, in existing support devices, the angle between the extension direction of the elastic component and the extension direction of the upper connecting arm changes during the height adjustment of the display device. Therefore, the support device needs to be designed with a certain amount of space to accommodate the change in the angle between the elastic component and the upper connecting arm, which makes the support device relatively large. Utility Model Content

[0003] The main purpose of this utility model is to provide a support device and a display device so that the support device can be easily miniaturized.

[0004] To achieve the above objectives, this utility model provides a support device, comprising: a cantilever component including a base, a connector, a first housing, and a swing arm; the two ends of the first housing are hinged to the base and the connector, respectively, and the two ends of the swing arm are hinged to the base and the connector, respectively, to form a quadrilateral structure; the connector is used to mount a display device; an elastic component located inside the swing arm; the first end of the elastic component is connected to the first housing, and the second end of the elastic component is movably disposed relative to the first housing; and a linkage component, one end of which is rotatably connected to the second end of the elastic component, and the other end of which is rotatably connected to the connector and / or the swing arm; during the rotation of the first housing and the swing arm around the base, the linkage component is used to drive the second end of the elastic component to move, so that the length of the elastic component changes, and the angle between the extension / retraction direction of the elastic component and the length direction of the first housing remains fixed.

[0005] Furthermore, the linkage component is located between the second end of the elastic component and the connector; the linkage component includes a linkage rod, one end of which is hinged to the second end of the elastic component, and the other end is hinged to the swing arm.

[0006] Furthermore, the elastic member includes an elastic element, one end of which is provided with a first connecting block in the extending direction, the end of the first connecting block away from the elastic element forms the second end of the elastic member, and one end of the linkage member is hinged to the end of the first connecting block away from the elastic element.

[0007] Furthermore, the support device also includes a rolling element, which is rotatably disposed at the second end of the elastic member. The first housing is provided with a guide surface, the extension direction of which is the same as the direction from the first end to the second end of the elastic member. The guide surface is located on the side where the rolling element is located, and the rolling element and the guide surface are in rolling engagement. Alternatively, the support device also includes a sliding element, which is rotatably disposed at the second end of the elastic member. The first housing is provided with a guide surface, the extension direction of which is the same as the direction from the first end to the second end of the elastic member. The guide surface is located on the side where the sliding element is located, and the sliding element and the guide surface are in sliding engagement.

[0008] Furthermore, a guide plate is provided on the side of the first outer shell facing the elastic member, and there is an angle between the guide plate and the first outer shell. The side of the guide plate facing the elastic member forms a guide surface.

[0009] Furthermore, the support device also includes an adjustment component, which includes: a second connecting block disposed at the first end of the elastic member; an adjustment member passing through the first housing, the adjustment member being rotatably disposed relative to the first housing, one end of the adjustment member being threadedly engaged with the second connecting block; and a screwing member disposed at the end of the adjustment member away from the second connecting block, which, by rotating the screwing member, can drive the adjustment member to rotate to adjust the preload of the elastic member.

[0010] Furthermore, the swing arm includes a first plate, a second plate, and a third plate connected in sequence. The first plate and the third plate are both located on the same side of the second plate. The first plate, the second plate, and the third plate cooperate to form a receiving groove. The elastic member and the linkage member pass through the receiving groove. The support device also includes a second outer shell. The first outer shell and the second outer shell are interlocked to form a receiving cavity for accommodating the swing arm. The first outer shell and the second outer shell are detachably connected.

[0011] Furthermore, the support device also includes a wire guide member disposed on the first housing and / or the second housing. At least a portion of the wire guide member passes through the receiving cavity and is located on one side of the elastic member.

[0014] By applying the technical solution of this utility model, when adjusting the height of the display device, the angle between the direction of the first end to the second end of the elastic member and the extension direction of the first outer shell remains unchanged. Thus, when designing the support device, there is no need to reserve a large space for the elastic member to achieve angle changes, which helps to reduce the overall volume of the support device.

[0015] Specifically, when adjusting the height of the display device, the first housing and the swing arm rotate synchronously relative to the base, changing the shape of the quadrilateral structure. The position of the connection point between one end of the linkage member and the connector and / or the swing arm relative to the hinge point of the first housing and the connector changes. Simultaneously, the linkage member rotates around its connection point with the connector and / or the swing arm. This allows the second end of the elastic member to move under the action of the linkage member, causing the elastic member to lengthen or shorten. With this configuration, the angle between the movement trajectory of the second end of the elastic member and the extension direction of the first housing remains constant; that is, the angle between the direction from the first end to the second end of the elastic member and the extension direction of the first housing remains constant. This configuration eliminates the need to reserve space for the elastic member to change angles when designing the support device, facilitating miniaturization of the support device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] like Figures 1 to 5As shown, Embodiment 1 of this utility model provides a support device, which includes a cantilever component 10, an elastic component 20, and a linkage component 30. The cantilever component 10 includes a base 11, a connector 12, a first housing 13, and a swing arm 14. The two ends of the first housing 13 are respectively hinged to the base 11 and the connector 12, and the two ends of the swing arm 14 are respectively hinged to the base 11 and the connector 12 to form a quadrilateral structure. The connector 12 is used to install a display device. The elastic component 20 is located inside the swing arm 14. The first end of the elastic component 20 is connected to the first housing 13, and the second end of the elastic component 20 is movably disposed relative to the first housing 13. One end of the linkage component 30 is rotatably connected to the second end of the elastic component 20, and the other end is rotatably connected to the connector 12 and / or the swing arm 14. During the rotation of the first housing 13 and the swing arm 14 around the base 11, the linkage component 30 is used to drive the second end of the elastic component 20 to move, so that the length of the elastic component 20 changes, and the angle between the extension and retraction direction of the elastic component 20 and the length direction of the first housing 13 remains fixed.

[0034] By applying the technical solution of this utility model, when adjusting the height of the display device, the angle between the direction of the first end to the second end of the elastic member 20 and the extension direction of the first outer shell 13 remains fixed. Thus, when designing the support device, there is no need to reserve a large space for the elastic member 20 to achieve angle changes, which helps to reduce the overall volume of the support device.

[0035] Specifically, when adjusting the height of the display device, the first housing 13 and the swing arm 14 rotate synchronously relative to the base 11, changing the shape of the quadrilateral structure. The position of the hinge point between one end of the linkage member 30 and the connector 12 and / or the swing arm 14 relative to the hinge point of the first housing 13 and the connector 12 changes. Simultaneously, the linkage member 30 rotates around its connection point with the connector 12 and / or the swing arm 14. This allows the second end of the elastic member 20 to move under the action of the linkage member 30, causing the elastic member 20 to lengthen or shorten. With this configuration, the angle between the movement trajectory of the second end of the elastic member 20 and the extension direction of the first housing 13 remains constant; that is, the angle between the direction from the first end to the second end of the elastic member 20 and the extension direction of the first housing 13 remains constant. This configuration eliminates the need to reserve space for the elastic member 20 to change its angle when designing the support device, facilitating miniaturization of the support device.

[0036] like Figures 3 to 5As shown, in this scheme, there is a hinge point A between the first outer shell 13 and the connector 12, a hinge point B between the first outer shell 13 and the base 11, a hinge point C between the swing arm 14 and the base 11, and a hinge point D between the swing arm 14 and the connector 12. The lines connecting hinge points A, B, C, and D form a parallelogram structure.

[0037] In some embodiments of this solution, one end of the linkage member 30 is hinged to the second end of the elastic member 20, and the other end is hinged to the connector 12.

[0038] In other embodiments of this solution, one end of the linkage member 30 is hinged to the second end of the elastic member 20, and the other end is simultaneously hinged to the connector 12 and the swing arm 14, that is, the hinge point of the connector 12 and the linkage member 30 coincide with the hinge point D. This improves the utilization rate of the hinge point D, and eliminates the need to set an additional hinge point for the other end of the linkage member 30, which helps to save processing costs.

[0039] In this embodiment, one end of the linkage member 30 is hinged to the second end of the elastic member 20, and the other end is hinged to the swing arm 14. The linkage member 30 has a hinge point E with the second end of the elastic member 20, and a hinge point F with the swing arm 14.

[0040] like Figures 2 to 4 As shown in the embodiment of this solution, the first end of the elastic member 20 is close to the base 11, and the second end of the elastic member 20 is close to the connector 12. The linkage member 30 includes a linkage rod, which is located between the second end of the elastic member 20 and the connector 12. One end of the linkage rod is hinged to the second end of the elastic member 20, and the other end is hinged to the swing arm 14. Setting the linkage member 30 as a rod-shaped structure provides a rigid and stable force transmission path, ensuring the reliability of the device. Furthermore, the linkage rod has a simple structure, facilitating maintenance and replacement. Since the linkage rod only needs to transmit force between the second end of the elastic member 20 and the swing arm 14, it does not need to be excessively long. Positioning the linkage rod between the elastic member 20 and the connector 12 eliminates the need for additional space, thus improving the structural compactness of the device and facilitating its miniaturization.

[0041] Furthermore, the elastic member 20 includes an elastic element 21, with a first connecting block 22 provided at one end of the elastic element 21 extending in the direction of extension. The end of the first connecting block 22 away from the elastic element 21 forms the second end of the elastic member 20, and one end of the linkage member 30 is hinged to the end of the first connecting block 22 away from the elastic element 21. The provision of the first connecting block 22 can improve the stability and reliability of the connection between the linkage rod and the second end of the elastic member 20.

[0042] In this embodiment, the swing arm 14 includes a first plate 141, a second plate 142, and a third plate 143 connected in sequence. The first plate 141 and the third plate 143 are both located on the same side of the second plate 142. The first plate 141, the second plate 142, and the third plate 143 cooperate to form a receiving groove 1401. The elastic member 20 and the linkage member 30 pass through the receiving groove 1401. The support device also includes a second outer shell 15. The first outer shell 13 and the second outer shell 15 are interlocked to form a receiving cavity 101 for accommodating the swing arm 14. The first outer shell 13 and the second outer shell 15 are detachably connected. This arrangement, embedding the elastic member 20 and the linkage member 30 inside the swing arm 14, can improve the space utilization of the receiving cavity 101 and enhance the structural compactness of the device.

[0043] Specifically, the elastic element 21, the first connecting block 22, and the linkage rod are all inserted into the receiving groove 1401.

[0044] Furthermore, the first plate 141 has a first extension piece 1411 at one end near the connector 12, and the third plate 143 has a second extension piece 1431 at one end near the connector 12. The first extension piece 1411 and the second extension piece 1431 protrude from the second plate 142 towards the connector 12. The connector 12 is located between the first extension piece 1411 and the second extension piece 1431. The end of the first extension piece 1411 away from the first plate 141 is hinged to the connector 12, and the end of the second extension piece 1431 away from the third plate 143 is hinged to the connector 12. This arrangement improves the stability of the hinge connection between the swing arm 14 and the connector 12, and the first extension piece 1411 and the second extension piece 1431 provide clearance for the relative rotation of the connector 12 and the swing arm 14.

[0045] In this embodiment, there are two linkage rods, which are parallel to each other and located on opposite sides of the first connecting block 22. One end of one linkage rod is hinged to the first connecting block 22, and the other end is hinged to the end of the first extension piece 1411 near the first plate 141; the other linkage rod is hinged to the first connecting block 22, and the other end is hinged to the end of the second extension piece 1431 near the third plate 143. The arrangement of two linkage rods can further improve the stability of force transmission.

[0046] Furthermore, the first plate 141 has a third extension piece 1412 at one end near the base 11, and the third plate 143 has a fourth extension piece 1432 at one end near the base 11. The third extension piece 1412 and the fourth extension piece 1432 protrude from the second plate 142 towards the base 11, and the base 11 is located between the third extension piece 1412 and the fourth extension piece 1432. The third extension piece 1412 and the fourth extension piece 1432 are respectively hinged to the base 11. This arrangement can improve the stability of the hinge between the swing arm 14 and the base 11, and the arrangement of the third extension piece 1412 and the fourth extension piece 1432 can provide clearance space for the relative rotation of the swing arm 14 and the base 11.

[0047] like Figure 2 and Figure 3 As shown in the embodiment of this solution, the support device further includes a rolling element 221. The rolling element 221 is rotatably disposed at the second end of the elastic member 20, specifically rotatably disposed on the first connecting block 22. The first outer shell 13 is provided with a guide surface 1301. The extending direction of the guide surface 1301 is the same as the direction from the first end to the second end of the elastic member 20. The guide surface 1301 is located on the side where the rolling element 221 is located, and the rolling element 221 rolls in cooperation with the guide surface 1301. The angle between the extending direction of the guide surface 1301 and the extending direction of the first outer shell 13 remains constant. The cooperation between the rolling element 221 and the guide surface 1301 restricts the movement trajectory of the first connecting block 22, so that the first connecting block 22 always moves along the extending direction of the guide surface 1301. Thus, the angle between the extension direction of the elastic member 21 and the extending direction of the guide surface 1301 remains constant, and the angle between the extension direction of the elastic member 21 and the extending direction of the first outer shell 13 remains constant. Furthermore, the rolling element 221 and the guide surface 1301 roll in a rolling engagement, resulting in rolling friction between the rolling element 221 and the guide surface 1301. The coefficient of friction between the two is low, which improves the smoothness of the rolling element 221 rolling on the guide surface 1301 and improves the smoothness of the extension and retraction process of the elastic element 21.

[0048] In this embodiment, the length direction of the first outer shell 13 is the same as the extension direction of the guide surface 1301, that is, when adjusting the height of the display device, the extension and retraction direction of the elastic element 21 is always the same as the length direction of the first outer shell 13.

[0049] In this embodiment of the solution, the rolling element 221 is a roller.

[0050] In other embodiments of this solution, the support device further includes a slider, which is rotatably disposed at the second end of the elastic member 20, specifically rotatably disposed on the first connecting block 22. The first outer shell 13 is provided with a guide surface 1301, the extension direction of which is the same as the direction from the first end to the second end of the elastic member 20. The guide surface 1301 is located on the side where the slider is located, and the slider slides in cooperation with the guide surface 1301. The slider is rotatably disposed on the first connecting block 22. This arrangement allows the slider to automatically adjust its contact angle with the guide surface 1301 as the elastic member 21 extends and retracts and the first outer shell 13 rotates, thus maintaining an optimal contact state with the guide surface 1301.

[0051] like Figure 2 and Figure 3 As shown, a guide plate 131 is provided on the side of the first outer shell 13 facing the elastic member 20. The guide plate 131 and the first outer shell 13 are an integral structure, and there is an included angle between the guide plate 131 and the first outer shell 13. The side of the guide plate 131 facing the elastic member 20 forms a guide surface 1301. This arrangement facilitates the processing and forming of the guide plate 131 and can improve the stability of the connection between the guide plate 131 and the first outer shell 13.

[0052] When the display device is initially in a lower first position, the elastic element 21 is in a state of extension to a certain extent. When the height of the display device is adjusted upward, the display device drives the connector 12 to move upward. The upward movement of the connector 12 causes the first housing 13 and the swing arm 14 to rotate synchronously relative to the base 11, and the angle of the parallelogram changes. Specifically, during the upward rotation of the swing arm 14, the position of the hinge point F between the linkage rod and the swing arm 14 relative to the hinge point A between the first housing 13 and the connector 12 will change, and the position of the hinge point E between the linkage rod and the first connecting block 22 relative to the hinge point A between the first housing 13 and the connector 12 will also change. Specifically, the distance between the hinge point E between the linkage rod and the first connecting block 22 and the hinge point A between the first housing 13 and the connector 12 gradually increases, the distance between the first connecting block 22 and the connector 12 increases, and the elastic element 21 is compressed. Under the action of the guide surface 1301 and the rolling element 221, the compression direction of the elastic element 21 is always the same as the length direction of the first housing 13.

[0053] When the display device is initially in a higher second position, the elastic element 21 is under a certain degree of compression. When the height of the display device is adjusted downwards, the display device drives the connector 12 to move downwards. The downward movement of the connector 12 causes the first housing 13 and the swing arm 14 to rotate synchronously relative to the base 11, and the angle of the parallelogram changes. Specifically, during the downward rotation of the swing arm 14, the position of the hinge point F between the linkage rod and the swing arm 14 relative to the hinge point A between the first housing 13 and the connector 12 changes, and the position of the hinge point E between the linkage rod and the first connecting block 22 relative to the hinge point A between the first housing 13 and the connector 12 also changes. Specifically, the distance between the hinge point E between the linkage rod and the first connecting block 22 and the hinge point A between the first housing 13 and the connector 12 gradually decreases. As the distance between the first connecting block 22 and the connector 12 decreases, the elastic element 21 elongates. Under the action of the guide surface 1301 and the rolling element 221, the elongation direction of the elastic element 21 is always the same as the length direction of the first housing 13.

[0054] like Figures 2 to 4 As shown, the support device also includes an adjusting component 40, which includes a second connecting block 41, an adjusting member 42, and a screwing member 43. The second connecting block 41 is disposed at the first end of the elastic member 20; the adjusting member 42 passes through the first housing 13 and is rotatably disposed relative to the first housing 13, with one end of the adjusting member 42 threadedly engaged with the second connecting block 41; the screwing member 43 is disposed at the end of the adjusting member 42 away from the second connecting block 41, and by rotating the screwing member 43, the adjusting member 42 can be rotated to adjust the preload of the elastic member 20.

[0055] The above configuration can accommodate display devices of different weights. Specifically, when the weight of the display device that the support device needs to support changes, for example, from a lighter device to a heavier device, the user can increase the preload of the elastic member 20 by rotating the screw 43 to compensate for the additional load caused by the increased weight of the display device. Conversely, if a lighter display device is used, the user can reduce the preload of the elastic member 20 by rotating the screw 43 to avoid unnecessary energy consumption caused by over-support. This configuration improves the adaptability of the device.

[0056] Specifically, the second connecting block 41 is a nut, and the adjusting component 42 is an adjusting screw.

[0057] Furthermore, the elastic element 21 is a spring, and the receiving cavity 101 formed by the spring, the adjusting screw, the first outer shell 13 and the second outer shell 15 after being fastened together is coaxially arranged.

[0058] like Figure 1 , Figure 2 and Figure 4As shown, the support device also includes a wire guide member 50, which is disposed on the first housing 13 and / or the second housing 15. At least a portion of the wire guide member 50 passes through the receiving cavity 101 and is located on one side of the elastic member 20. The wire guide member 50 has a first wire guide hole 501, a wire guide channel 502 and a second wire guide hole 503 that are interconnected for the wire to pass through.

[0059] In this embodiment, the first outer shell 13 and the second outer shell 15 are fastened together to form a mounting hole 102. The mounting hole 102 communicates with the side of the receiving cavity 101, and the wire guide member 50 is disposed at the mounting hole 102.

[0060] Specifically, the mounting hole 102 is positioned opposite to the second plate 142 of the swing arm 14 and is located on the side of the third plate 143 and the first plate 141 away from the second plate 142. The cable guide component 50 includes a fixing seat 51 and a cover 52. The fixing seat 51 has a blocking end and an open end that are positioned opposite each other. The fixing seat 51 is located at the mounting hole 102, and the blocking end is located inside the receiving cavity 101. The blocking end and the second plate 142 are located on opposite sides of the elastic member 21. The cover 52 is placed over the open end of the fixing seat 51, so that the cable guide component 50 forms an interconnected first cable guide hole 501, a cable guide channel 502, and a second cable guide hole 503. This arrangement makes reasonable use of the space inside the receiving cavity 101 and avoids the possibility of interference between the cable extending into the receiving cavity 101 and other components.

[0061] Furthermore, the base 11 is pivotally connected to the first outer shell 13. Specifically, a pivot shaft is provided on the side of the base 11 facing the first outer shell 13, and a connecting hole 133 is provided on the side of the first outer shell 13 facing the base 11, with the pivot shaft passing through the connecting hole 133. The support device also includes an anti-detachment part 132, which is a sheet metal part. One end of the anti-detachment part 132 is fixedly connected to the first outer shell 13, and the other end is pivotally connected to the base 11. The pivot axis of the anti-detachment part 132 and the first outer shell 13 coincides with the pivot axis of the base 11 and the first outer shell 13, to prevent the base 11 from detaching from the first outer shell 13. This arrangement avoids the hinge point between the base 11 and the first outer shell 13 being exposed, improving the aesthetics of the device.

[0062] This utility model provides a display device in embodiment two, which includes a support device, a mounting panel 60, and a display device as described in embodiment one. The mounting panel 60 is disposed on the connector 12; the display device is mounted on the mounting panel 60.

[0063] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0064] 1. By designing the linkage component 30, the angle between the extension and retraction direction of the elastic component 20 and the extension direction of the first outer shell 13 remains unchanged during the height adjustment process of the display device. Therefore, when designing the support device, there is no need to reserve extra space to accommodate the angle change of the elastic component 20, which helps to reduce the overall volume of the support device and realize the miniaturization of the support device.

[0065] 2.
