Description

Technical Field

[0001] This utility model belongs to the field of bracket technology, and in particular relates to an electric rotating device and a display support device. Background Technology

[0002] Currently, computer monitors, televisions, and other display devices are mostly installed using dedicated stands. These monitor stands not only fix the device to the wall or a designated location, effectively saving floor and desktop space in living rooms, bedrooms, and other spaces, making the environment more tidy; they also support height adjustment and left and right rotation adjustment, adapting to different usage postures such as lying down and standing, significantly improving the user's viewing and usage experience.

[0003] In existing technologies, some monitor stands are equipped with matching cabinets. The stand can move the monitor up and down and store it inside the cabinet. However, the opening shape of these cabinets is fixed, and the monitor needs to be rotated to a specific angle to smoothly enter the cabinet. However, the rotation angle of existing monitor stands generally lacks precise control, resulting in poor angle adjustment accuracy. This makes them prone to collisions with the cabinet during storage, seriously affecting the safety of the display device.

[0004] Therefore, there is an urgent need for an electric rotating device and a display support device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric rotating device and a display support device, which realizes precise control of the angle of the display device entering the cabinet and improves the safety when the display device is stored in the cabinet.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On one hand, an electrically driven rotating device is provided, comprising:

[0008] Fixed support and rotating support, the rotating support rotating relative to the fixed support;

[0009] At least one position identification element is disposed on one of the fixed bracket and the rotating bracket, and the position identification element includes a first identification part and a second identification part;

[0010] A triggering component is disposed on the other of the fixed bracket and the rotating bracket. When the rotating bracket rotates relative to the fixed bracket, the position identification component moves relative to the triggering component. When the triggering component contacts both the first identification part and the second identification part of either position identification component, the position identification component is triggered.

[0011] Optionally, the triggering component is mounted on the rotating bracket, and the position recognition component is mounted on the fixed bracket;

[0012] The triggering component includes an elastic element and a trigger element. One end of the elastic element is connected to the rotating bracket, and the other end of the elastic element is connected to the trigger element. When the triggering component moves to the position of the position recognition element, the trigger element is electrically connected to both the first recognition part and the second recognition part. The position recognition element is triggered, and the rotating bracket stops rotating.

[0013] Optionally, the trigger includes a conductive spherical surface, and when the position recognition element is triggered by the triggering component, the conductive spherical surface contacts the first recognition part and the second recognition part.

[0014] Optionally, the electric rotating device also includes a first controller, and the first identification unit, the second identification unit and the rotating bracket are all electrically connected to the first controller. The first controller is used to control the rotating bracket to stop rotating when the position identification element is triggered.

[0015] Optionally, the fixed bracket is provided with a first groove, and the position identification element is disposed in the first groove.

[0016] Optionally, a gap is provided between the first identification part and the second identification part, and when the position identification element is triggered, the triggering component is located within the gap.

[0017] Optionally, the rotating bracket includes a bracket body, a rotating drive unit, and a rotating shaft. The rotating shaft is rotatably connected to the bracket body, and the output shaft of the rotating drive unit is connected to the rotating shaft. The output shaft of the rotating drive unit and the rotating shaft are arranged coaxially or off-axis.

[0018] Optionally, two position identifiers are set, with a spacing between them, and the trigger component moves between the two position identifiers.

[0019] On the other hand, a display support device is provided, including a lifting column, a display device bracket, a second controller, and the aforementioned electric rotating device. The display device bracket is disposed on the top of the lifting column and is used to support the display device. The lifting column is connected to the electric rotating device, and the second controller is connected to the lifting column and is used to control the lifting and lowering of the lifting column.

[0020] Optionally, the display device bracket is provided with a connecting groove, and the lifting column structure and electric rotating device are located in the connecting groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model provides an electric rotating device and a display support device. When the rotating bracket rotates relative to the fixed bracket, a position identification element or triggering component mounted on the rotating bracket can move under the drive of the rotating bracket, thereby causing relative movement between the position identification element and the triggering component. When the triggering component moves to contact both the first and second identification parts of the position identification element, the position identification element is triggered, and the rotating bracket stops rotating. At this time, the position identification element and the triggering component no longer move relative to each other, and the fixed bracket and the rotating bracket no longer rotate relative to each other. By setting the first and second identification parts, the accuracy of identifying the stop position of the rotating bracket and the positioning stability can be significantly improved. When the second controller controls the lifting column to rise and fall, it can drive the display device to rise and fall together through the display device bracket located at its top, so as to realize the storage of the display device in the cabinet or its extension out of the cabinet. When the rotating bracket stops rotating, the lifting column connected to the electric rotating device also stops rotating, and consequently the display device installed on the display device bracket stops rotating. This achieves precise control over the angle at which the display device enters the cabinet, allowing it to automatically stop rotating when it reaches an angle corresponding to the opening on the cabinet. This improves the accuracy of the position of the display device and its bracket when being stored in the cabinet, as well as the safety of its use. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] Example 1

[0047] like Figures 1 to 8 As shown, Embodiment 1 provides an electric rotating device 100, which enables precise control of the angle at which the display device enters the cabinet, thereby improving the safety of the display device when it is stored in the cabinet.

[0048] See Figure 1 and Figure 2 The electric rotating device 100 includes a fixed bracket 110, a rotating bracket 120, a triggering assembly 130, and at least one position identification element 140. The rotating bracket 120 rotates relative to the fixed bracket 110. The position identification element 140 is disposed on one of the fixed bracket 110 and the rotating bracket 120, and includes a first identification portion 141 and a second identification portion 142. The triggering assembly 130 is disposed on the other of the fixed bracket 110 and the rotating bracket 120. When the rotating bracket 120 rotates relative to the fixed bracket 110, the position identification element 140 moves relative to the triggering assembly 130. When the triggering assembly 130 contacts both the first identification portion 141 and the second identification portion 142 of any one of the position identification elements 140, the position identification element 140 is triggered.

[0049] In the electric rotating device 100 provided in this embodiment, when the rotating bracket 120 rotates relative to the fixed bracket 110, the position identification element 140 or the triggering component 130 disposed on the rotating bracket 120 can move under the drive of the rotating bracket 120, thereby causing relative movement between the position identification element 140 and the triggering component 130. When the triggering component 130 moves to contact both the first identification part 141 and the second identification part 142 of the position identification element 140, the position identification element 140 is triggered, and the rotating bracket 120 stops rotating. At this time, the position identification element 140 and the triggering component 130 no longer move relative to each other, and the fixed bracket 110 and the rotating bracket 120 no longer rotate relative to each other. By providing the first identification part 141 and the second identification part 142, the accuracy of identifying the stopped position of the rotating bracket 120 and the positioning stability can be significantly improved.

[0050] Specifically, see Figure 3 When the rotating bracket 120 rotates, it drives the trigger component 130 to move relative to the position recognition component 140.

[0051] For example, see Figure 3 The rotating bracket 120 has a circular cross-sectional shape and is rotatably mounted on one side of the fixed bracket 110 around its own axis. This arrangement not only ensures that the rotating bracket 120 is evenly stressed during rotation, improving its stability, but also reduces friction between the rotating bracket 120 and surrounding structures, thus lowering its energy consumption and wear. In other embodiments, the rotating bracket 120 may have a rectangular or other cross-sectional shape.

[0052] Optionally, see Figure 3 , Figure 4 and Figure 5 A trigger assembly 130 is mounted on the rotating bracket 120, and a position identification element 140 is mounted on the fixed bracket 110. The trigger assembly 130 includes an elastic element 131 and a trigger element 132. One end of the elastic element 131 is connected to the rotating bracket 120, and the other end of the elastic element 131 is connected to the trigger element 132. When the trigger assembly 130 moves to the position of the position identification element 140, the trigger element 132 is electrically connected to both the first identification element 141 and the second identification element 142, triggering the position identification element 140 and stopping the rotation of the rotating bracket 120. The trigger element 132 triggers the position identification element 140 through electrical contact, so that after the trigger assembly 130 contacts the first identification element 141 and the second identification element 142, a conductive path can be formed between the trigger assembly 130 and the position identification element 140 to control the rotation of the rotating bracket 120. The elastic element 131 exerts a spring force on the trigger element 132, so that when the trigger assembly 130 moves to the position recognition element 140, the trigger element 132 can contact the first recognition part 141 and the second recognition part 142 under the action of the elastic element 131 and generate a certain squeezing force, thereby ensuring that the trigger element 132 can make stable contact with the first recognition part 141 and the second recognition part 142, improving the stability of the conductive path, ensuring the stability of the relative position between the rotating bracket 120 and the fixed bracket 110 at this time, and the display device can be stably limited to the current rotation angle.

[0053] For example, see Figure 5 The elastic element 131 is a spring.

[0054] Specifically, see Figure 3 and Figure 5The trigger assembly 130 also includes a trigger seat 133, which is fixedly connected to the rotating bracket 120. The trigger seat 133 has a channel, in which the elastic element 131 and the trigger element 132 are housed. Part of the structure of the trigger element 132 can be exposed outside the trigger seat 133 through the channel opening. One end of the elastic element 131 is connected to the rotating bracket 120, and the other end of the elastic element 131 abuts against the trigger element 132.

[0055] In this embodiment, see Figure 3 , Figure 4 and Figure 6 A circuit board 111 is provided on the fixed bracket 110, and at least two position identification elements 140 are provided. Both position identification elements 140 are provided on the circuit board 111. The circuit board 111 is electrically connected to the position identification elements 140 and the rotation drive part 122 of the rotating bracket 120, forming a conductive path from the rotating bracket 120 to the fixed bracket 110, so that the rotating bracket 120 can stop rotating when the position identification element 140 is triggered by the triggering component 130.

[0056] Specifically, see Figure 1 and Figure 3 The circuit board 111 has identification positions 1111, and each position identification element 140 has one identification position 1111. A first identification part 141 and a second identification part 142 are located on either side of the corresponding identification position 1111. When the trigger element 132 does not trigger the position identification element 140, the trigger element 132 abuts against the surface of the circuit board 111, and the elastic element 131 is in a compressed state. When the trigger element 132 contacts the first identification part 141 and the second identification part 142, the elastic element 131 recovers its deformation, causing the trigger element 132 to be pressed against the first identification part 141 and the second identification part 142 under the elastic force of the elastic element 131, and the trigger element 132 is at least partially located within the identification position 1111. The identification positions 1111 help to further constrain the movement of the trigger element 132 between the first identification part 141 and the second identification part 142, ensuring stable contact between the trigger element 132 and the first identification part 141 and the second identification part 142, further improving the stability of the conductive path.

[0057] For example, the identification bit 1111 includes, but is not limited to, an identification slot or an identification hole.

[0058] Furthermore, the fixed bracket 110 is provided with a vibration isolation pad, which is located between the circuit board 111 and the fixed bracket 110. This helps to avoid hard contact between the circuit board 111 and the fixed bracket 110, thereby improving the service life of the circuit board 111 and the fixed bracket 110.

[0059] In this embodiment, the trigger 132 includes a conductive spherical surface. When the position recognition element 140 is triggered by the trigger assembly 130, the conductive spherical surface contacts the first recognition part 141 and the second recognition part 142, realizing an electrical connection between the trigger 132 and the position recognition element 140. At this time, the first recognition part 141 and the second recognition part 142 are connected through the trigger 132, generating a trigger signal, and the rotating bracket 120 stops rotating. The conductive spherical surface has complete symmetry in three-dimensional space, so that its triggering effect on the first recognition part 141 and the second recognition part 142 remains consistent regardless of which direction it contacts them. Moreover, when the conductive spherical surface contacts the first recognition part 141 and the second recognition part 142, the friction between it and the first recognition part 141 and the second recognition part 142 is rolling friction, which significantly reduces the friction force compared to planar or cylindrical sliding friction, thereby helping to extend the service life of the trigger 132 and the position recognition element 140.

[0060] For example, see Figure 5 The trigger element 132 is made of steel ball, and its outer surface forms a conductive spherical surface.

[0061] In this embodiment, see Figure 1 and Figure 3 The fixed bracket 110 is provided with a first groove 112, and the position identification component 140 is disposed in the first groove 112 to realize the installation of the position identification component 140 on the fixed bracket 110.

[0062] Specifically, see Figure 1 and Figure 3 A circuit board 111 is provided on the fixed bracket 110, and several position identification elements 140 are all disposed on the circuit board 111. The circuit board 111 is confined within the first groove 112, so that the several position identification elements 140 can be disposed within the first groove 112 through the circuit board 111.

[0063] Further, see Figure 1 and Figure 3 The fixed bracket 110 is provided with multiple stepped limiting members 113, which are spaced apart circumferentially along the circuit board 111, forming a first groove 112. This arrangement not only enables the installation of the position identification member 140 within the first groove 112, but also helps reduce the manufacturing cost of forming the first groove 112, thus exhibiting good economic efficiency.

[0064] For example, the stepped limiter 113 is a plate.

[0065] In this embodiment, the electric rotating device 100 further includes a first controller. The first identification unit 141, the second identification unit 142, and the rotating bracket 120 are all electrically connected to the first controller. The first controller is used to control the rotating bracket 120 to stop rotating when the position identification unit 140 is triggered. When the triggering unit 132 is not in electrical contact with the first identification unit 141 and the second identification unit 142, the first identification unit 141 and the second identification unit 142 cannot conduct, and cannot generate a trigger signal. The first controller does not receive a trigger signal and controls the rotating bracket 120 to rotate. When the triggering unit 132 makes electrical contact with the first identification unit 141 and the second identification unit 142, a trigger signal is generated and transmitted to the first controller. The first controller controls the rotating bracket 120 to stop rotating, improving the accuracy of the stopping position of the rotating bracket 120 and the degree of automation of the rotation of the rotating bracket 120. That is, after the triggering unit 130 makes electrical contact with the first identification unit 141 and the second identification unit 142, the first identification unit 141 and the second identification unit 142 form a path and generate a trigger signal.

[0066] Optionally, see Figure 1 and Figure 2 A gap 143 is provided between the first identification part 141 and the second identification part 142. When the position identification element 140 is triggered, a portion of the structure of the triggering component 130 is located within the gap 143. This arrangement ensures that when the triggering component 130 moves to the position identification element 140, it can simultaneously contact the first identification part 141 and the second identification part 142. Furthermore, it also ensures that when the rotating bracket 120 is driven to rotate again, the position identification element 140 can pass through the gap 143, and the first identification part 141 and the second identification part 142 will not affect the movement of the triggering component 130.

[0067] Specifically, the trigger component 130 is disposed on the rotating bracket 120, the position identification component 140 is disposed on the fixed bracket 110, and the fixed bracket 110 is provided with an identification position 1111, which is located at the gap 143 between the first identification part 141 and the second identification part 142.

[0068] Optionally, see Figure 3 and Figure 4The rotating bracket 120 includes a bracket body 121, a rotating drive unit 122, and a rotating shaft 123. The rotating shaft 123 is rotatably connected to the bracket body 121. The output shaft of the rotating drive unit 122 is connected to the rotating shaft 123. The output shaft of the rotating drive unit 122 and the rotating shaft 123 are arranged coaxially or offset. When the rotating drive unit 122 drives the rotating shaft 123 to rotate, the rotating shaft 123 can drive the bracket body 121 to rotate, and then the bracket body 121 can drive the trigger component 130 or several position identification elements 140 mounted on it to move circumferentially. The output shaft of the rotating drive unit 122 and the rotating shaft 123 have two different arrangements, which allows the rotating bracket 120 to be flexibly arranged according to its use, improving the versatility and flexibility of the electric rotating device 100.

[0069] Specifically, the electric rotating device 100 also includes a first controller, which is electrically connected to the rotating drive unit 122 and is used to control the opening and closing of the rotating drive unit 122.

[0070] For example, the rotary drive unit 122 is a motor.

[0071] Specifically, the rotating shaft 123 passes through the bracket body 121. The rotating bracket 120 also includes a clamping member, which passes through the bracket body 121 and clamps the rotating shaft 123, which helps to eliminate the gap between the rotating shaft 123 and the bracket body 121, so that there is no play between the rotating shaft 123 and the bracket body 121 when the rotating shaft 123 rotates.

[0072] For example, the clamping element is a bolt, which is threaded to the bracket body 121.

[0073] In this embodiment, see Figure 1 , Figure 3 and Figure 7 The output shaft of the rotary drive unit 122 and the rotating shaft 123 are arranged coaxially, that is, the axes of the output shaft of the rotary drive unit 122 and the rotating shaft 123 are a straight line, which helps to reduce the space occupied by the overall rotating bracket 120 and can be applied to compact equipment.

[0074] In other embodiments, see Figure 2 , Figure 4 and Figure 8 The output shaft of the rotary drive unit 122 and the rotating shaft 123 are arranged in a staggered manner, that is, the axes of the output shaft of the rotary drive unit 122 and the rotating shaft 123 are two non-coincident straight lines, which can meet the needs of multi-directional power output and complex spatial layout.

[0075] Specifically, see Figure 2 and Figure 4The rotating bracket 120 also includes a driving gear 124 and a driven gear 125 that mesh with each other. The trigger assembly 130 is disposed on the driving gear 124. The output shaft of the rotating drive unit 122 passes through the driving gear 124, and the rotating shaft 123 passes through the driven gear 125. The output shaft of the rotating drive unit 122 drives the driving gear 124 to rotate, and the driving gear 124 drives the rotating shaft 123 to rotate through the driven gear 125.

[0076] For example, the output shaft of the rotary drive unit 122 and the axis of the rotating shaft 123 can be parallel to each other or set at an angle.

[0077] Optionally, see Figure 1 and Figure 2 There are two position identification elements 140, and the two position identification elements 140 are spaced apart. The trigger component 130 moves between the two position identification elements 140, so that the rotating bracket 120 can have two rotation stop positions.

[0078] In this embodiment, when the electric rotating device 100 is installed on the monitor bracket, the monitor has a plate-like structure, the monitor bracket is set on a cabinet, and the cabinet is provided with a strip-shaped storage opening. To ensure that the monitor can be smoothly stored in the cabinet through the strip-shaped storage opening, the included angle between the two position identification elements 140 is preferably 180°.

[0079] Specifically, see Figure 1 In terms of orientation, the trigger component 130 can only move clockwise from the right position identifier 140 to the left position identifier 140. When the trigger component 130 needs to move from the right position identifier 140 to the left position identifier 140, it can only rotate counterclockwise, and the clockwise and counterclockwise rotation angles are the same. Since the monitor has multiple wires connected to it, when the monitor is stored inside the cabinet, the user cannot observe the arrangement of the wires. Therefore, the above operation effectively prevents the wires from becoming tangled inside the cabinet.

[0080] In other embodiments, the position identification element 140 may be provided as a single unit or as two or more units. When there are two or more position identification elements 140, the multiple position identification elements 140 are arranged at circumferential intervals along the rotating bracket 120 or the fixed bracket 110, and the included angle between two adjacent position identification elements 140 is determined according to the specific equipment used by the electric rotating device 100.

[0081] Example 2

[0082] Based on the same inventive concept as Embodiment 1, this embodiment provides an electric rotating device 100. The difference between this embodiment and Embodiment 1 is that the trigger component 130 is disposed on the fixed bracket 110, and the position identification component 140 is disposed on the rotating bracket 120.

[0083] In this embodiment, the triggering component 130 includes an elastic element 131 and a triggering element 132. One end of the elastic element 131 is connected to the fixed bracket 110, and the other end of the elastic element 131 is connected to the triggering element 132.

[0084] In this embodiment, the circuit board 111 is mounted on the rotating bracket 120.

[0085] In this embodiment, a second groove is provided on the rotating bracket 120, and the position identification component 140 is disposed in the second groove to realize the installation of the position identification component 140 on the rotating bracket 120.

[0086] Example 3

[0087] Based on the same inventive concept as Embodiment 1, this embodiment provides an electric rotating device 100. The difference between this embodiment and Embodiment 1 is that both the first identification part 141 and the second identification part 142 are provided with buttons. When the triggering component 130 contacts the first identification part 141 and the second identification part 142, the buttons on the first identification part 141 and the second identification part 142 are simultaneously pressed by the triggering component 130 to trigger the position identification element 140, and the rotating bracket 120 stops rotating.

[0088] This embodiment is applicable to both the case where the trigger component 130 is mounted on the rotating bracket 120 and the position identification component 140 is mounted on the fixed bracket 110, and the case where the trigger component 130 is mounted on the fixed bracket 110 and the position identification component 140 is mounted on the rotating bracket 120.

[0089] Example 4

[0090] like Figures 1 to 11 As shown, Embodiment 4 provides a display support device, including a lifting column 200, a display device bracket 300, a second controller, and the aforementioned electric rotating device 100. The display device bracket 300 is disposed on the top of the lifting column 200 and is used to support the display device. The lifting column 200 is connected to the electric rotating device 100, and the second controller is connected to the lifting column 200 and is used to control the lifting of the lifting column 200.

[0091] The electric rotating device 100 can be any one of Embodiment 1, Embodiment 2 and Embodiment 3.

[0092] When the second controller controls the lifting column 200 to rise and fall, it can also lift and fall the display device along with it via the display device bracket 300 located at its top, so as to realize the storage of the display device in the cabinet or its extension out of the cabinet. When the rotating bracket 120 stops rotating, the lifting column 200 connected to the electric rotating device 100 can also stop rotating, and the display device installed on the display device bracket 300 can stop rotating. This achieves precise control of the angle at which the display device enters the cabinet, so that the display device can automatically stop rotating when it rotates to the angle corresponding to the opening on the cabinet. This improves the accuracy of the position of the display device and the display device bracket 300 when they are stored in the cabinet and enhances the safety of use.

[0093] For example, the display device is a monitor, and the monitor support device is a monitor stand.

[0094] In this embodiment, see Figure 1 , Figure 7 and Figure 9 When the output shaft of the rotary drive unit 122 and the rotating shaft 123 are arranged coaxially, the display support device also includes a mounting cylinder 210, which is disposed on the top of the lifting column 200. The display device bracket 300 is rotatably connected to the lifting column 200 through the mounting cylinder 210. The electric rotating device 100 is located in the inner cavity of the mounting cylinder 210. The bracket body 121 of the rotating bracket 120 is rotatably engaged with the mounting cylinder 210. The position identification element 140 is disposed on the fixed bracket 110, and the triggering component 130 is disposed on the bracket body 121.

[0095] Specifically, see Figure 1 , Figure 7 and 10 The bracket body 121, rotating shaft 123, fixed bracket 110, and mounting cylinder 210 are coaxially arranged. The rotating shaft 123 passes through the fixed bracket 110 and the bracket body 121 and is connected to the display device bracket 300. The rotating shaft 123 is rotatably engaged with the fixed bracket 110. When the first controller activates the rotation drive unit 122, the rotation drive unit 122 drives the rotating shaft 123 to rotate, and the rotating shaft 123 drives the bracket body 121 and the display device bracket 300 to rotate together. When the trigger component 130 makes electrical contact with the first identification part 141 and the second identification part 142 of a position identification element 140, a conductive path is formed between the trigger component 130 and the position identification element 140. The first controller then deactivates the rotation drive unit 122, and the bracket body 121 and the display device bracket 300 stop rotating together.

[0096] For example, the bracket body 121 of the rotating bracket 120 is rotatably engaged with the mounting cylinder 210 via a bearing.

[0097] Optionally, see Figure 7 and Figure 9The display device bracket 300 is provided with a connecting groove 310, and part of the lifting column 200 structure and the electric rotating device 100 are located within the connecting groove 310. This arrangement helps to increase the connection area between the lifting column 200 and the display device bracket 300, preventing the display device bracket 300 from tipping over on the lifting column 200, improving the stability of the display device bracket 300 installed on the lifting column 200, and ensuring the reliability of the display device installed on the display support device.

[0098] In this embodiment, see Figure 9 The display support device also includes a connector 400, which is located in the connecting groove 310. One end of the connector 400 is connected to the groove wall of the connecting groove 310, and the other end is connected to the lifting column 200, which further increases the connection strength between the lifting column 200 and the display device bracket 300 and improves the stability of the display device bracket 300 installed on the lifting column 200.

[0099] Specifically, see Figure 4 , Figure 7 and Figure 9 The connector 400 includes a connecting ring. When the output shaft of the rotary drive unit 122 and the rotating shaft 123 are arranged coaxially, the mounting cylinder 210 is located in the connecting groove 310, and the connecting ring is sleeved on the mounting cylinder 210; when the output shaft of the rotary drive unit 122 and the rotating shaft 123 are arranged off-axis, the mounting base 220 is located in the connecting groove 310, and the connecting ring is sleeved on the mounting base 220.

[0100] Example 5

[0101] Based on the same inventive concept as Embodiment 4, this embodiment provides a display support device. The difference between this embodiment and Embodiment 4 is that the output shaft of the rotary drive unit 122 is arranged off-axis from the rotating shaft 123 through the driving gear 124 and the driven gear 125.

[0102] In this embodiment, see Figure 2 , Figure 10 and Figure 11 The display support device also includes a mounting base 220 disposed on the lifting column 200, and the display device bracket 300 is rotatably connected to the lifting column 200 via the mounting base 220. An electric rotating device 100 is disposed on the mounting base 220, a position identification element 140 is disposed on the fixed bracket 110, and a trigger component 130 is disposed on the drive gear 124.

[0103] Specifically, see Figure 2The rotating shaft 123 is parallel to the output shaft of the rotating drive unit 122. The rotating shaft 123 passes through the driven gear 125 and the fixed bracket 110 and is connected to the display device bracket 300. The rotating shaft 123 and the fixed bracket 110 are rotatably engaged. When the first controller turns on the rotating drive unit 122, the rotating drive unit 122 drives the driving gear 124 to rotate. The driving gear 124 drives the rotating shaft 123 to rotate through the driven gear 125. The driven gear 125 drives the trigger component 130 to move. The rotating shaft 123 drives the display device bracket 300 to rotate together. When the trigger component 130 makes electrical contact with the first identification part 141 and the second identification part 142 of a position identification element 140, a conductive path is formed between the trigger component 130 and the position identification element 140. The first controller turns off the rotating drive unit 122, and the driven gear 125 and the display device bracket 300 stop rotating together.

[0104] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
