In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The invention provides a supporting device.

In an embodiment of the present invention, referring to fig. 1, fig. 2, fig. 3, fig. 10, fig. 11, fig. 12 and fig. 15, the supporting device includes a chassis 100, a column module 200 and a mounting head module 300; the column module 200 includes a column body 210, a fixing component 220 and a rotating component 230, wherein the column body 210 extends along a vertical direction, the fixing component 220 is fixedly connected to the bottom end of the column body 210, the rotating component 230 is fixedly connected to the chassis 100, and the fixing component 220 is rotatably connected to the rotating component 230 and can rotate in a horizontal plane; the mounting head module 300 is mounted on the top end of the mast body 210, and the mounting head module 300 can rotate relative to the mast module 200 in two vertical planes perpendicular to each other.

The chassis 100 in the support device provides a support base to increase the contact area with the table top or table top, which in turn increases the stability of the support device. The stand module 200 is used to provide a greater supporting strength, and enable the display device or other products mounted on the supporting device to have a certain height, so as to be convenient for the user to view or use. The column body 210 of the column module 200 extends in the vertical direction, and the fixing component 220 of the column module 200 is fixedly connected to the bottom end of the column body 210, for example, an integrally formed structure may be integrally fixed, or a screw connection manner may be adopted, or a snap connection manner may be adopted. The rotating component 230 of the stand column module 200 is rotatably connected with the fixing component 220 and fixedly connected with the chassis 100, so that the stand column module 200 can rotate in a horizontal plane relative to the chassis 100, and then the effect that the supporting device can drive a display device or other products installed on the supporting device to rotate in the horizontal plane so as to adjust the installation angle is achieved. Specifically, one of the fixed component 220 and the rotating component 230 is provided with a through hole, and the other is provided with a rotating shaft, and the rotating shaft is inserted into the through hole, so that the relative rotation effect of the fixed component and the rotating component is realized. In addition, by fixedly connecting the rotating component 230 of the column module 200 with the chassis 100, the column body 210, the fixing component 220 and the rotating component 230 are conveniently integrally connected with the chassis 100 after being firstly combined into a module, and can also be applied to scenes connected with other components, so that the universality of the column module 200 is conveniently realized. In addition, the bottom of the column module 200 and the chassis 100 rotate relatively to realize the effect that the supporting device drives the display device mounted thereon to rotate, and a user can apply a driving torque to the column module 200 to realize the effect that the fixing component 220 of the column module 200 rotates relative to the rotating component 230, so that the risk of easily toppling the display device on the supporting device when the display device rotates in a horizontal plane is reduced. It can be understood that, if the top ends of the mounting head module 300 and the column module 200 are relatively rotated to drive the supporting device to rotate in the horizontal plane, the user can only apply a driving moment to the mounting head module 300, at this time, while the mounting head module 300 is driven to rotate in the horizontal plane relative to the column module 200, the column module 200 is easy to tilt or even topple due to the fact that the column module 200 is long, and it is difficult to ensure the stability of driving the display device or other products to rotate in the horizontal plane. Further, in order to reduce the friction force when the fixed component 220 rotates relative to the rotating component 230, at least one of the fixed component 220 and the rotating component 230 may be provided with an oil storage tank, and lubricating oil is stored in the oil storage tank, so that the lubricating oil can lubricate the surface of the fixed component 220 facing the rotating component 230, the friction force when the fixed component 220 rotates relative to the rotating component 230 is reduced, and the risk of jamming when the fixed component rotates due to a large total load of the mounting head module 300, the upright module 200, and a product mounted on the mounting head module 300 is avoided.

By mounting the mounting head module 300 on the top end of the column module 200 and being able to rotate relative to the column module 200 in two vertical planes perpendicular to each other, the effect that the product on the mounting head module 300 can rotate in the two vertical planes perpendicular to each other is also achieved. Specifically, mounting head module 300 can be movably mounted on the top of stud module 200, or mounting head module 300 can rotate in two vertical planes perpendicular to each other, and is connected to stud module 200 in a fixed manner. For example, the mounting head module 300 can rotate in two vertical planes perpendicular to each other, and the mounting head module 300 has at least two sets of rotating mechanisms, and when the two sets of rotating mechanisms are connected to each other, the movable members of one set of rotating mechanisms can be fixedly connected to the fixed members of the other set of rotating mechanisms. That is, head module 300 includes pitch mechanism 310 and pivot mechanism 320, pitch mechanism 310 includes pitch fixed bracket 311 and pitch movable bracket 312, and pitch movable bracket 312 is rotatably connected to pitch fixed bracket 311; the pivoting mechanism 320 includes a pivoting fixed bracket 321 and a pivoting movable bracket 322, the pivoting movable bracket 322 is rotatably connected to the pivoting fixed bracket 321, the pivoting fixed bracket 321 is connected to the pitching movable bracket 312, and the pitching fixed bracket 311 is fixedly installed at the top end of the upright body 210. Alternatively, the mounting head module 300 includes a set of pivoting mechanisms 320, each pivoting mechanism 320 has a pivoting fixed bracket 321 and a pivoting movable bracket 322, the pivoting movable bracket 322 is rotatably connected to the pivoting fixed bracket 321, the pivoting fixed bracket 321 is rotatably connected to the top end of the stud body 210, and the rotating shaft of the pivoting fixed bracket 321 relative to the stud body 210 is perpendicular to the rotating shaft of the pivoting movable bracket 322 relative to the pivoting fixed bracket 321. In the technical scheme of the invention, the upright post module 200 rotates in a horizontal plane relative to the chassis 100, and the head mounting module 300 can rotate in two vertical planes which are perpendicular to each other, so that a product mounted on the head mounting module 300 has the effect of rotating in different directions of a three-dimensional space, and the functions of the supporting device are diversified.

According to the technical scheme, the fixing component 220 is fixedly connected to the bottom end of the upright post body 210, the fixing component 220 is rotatably connected with the rotating component 230, and the rotating component 230 is connected with the chassis 100, so that the bottom end of the upright post module 200 can rotate in a horizontal plane relative to the chassis 100, and then the effect that the supporting device drives a product mounted on the supporting device to rotate in the horizontal plane so as to adjust the mounting angle is achieved; and also avoids the risk of tipping over easily when the product on the drive support is rotated in a horizontal plane. In addition, the mounting head module 300 is mounted on the top end of the column module 200, so that the mounting height of the product can be increased after the product is mounted on the mounting head module 300, and the product can be supported well. The mounting head module 300 can rotate relative to the upright module 200 in two vertical planes perpendicular to each other, so that a product mounted on the supporting device can rotate in the two vertical planes perpendicular to each other under the driving of the mounting head module 300, thereby realizing the effect that the supporting device drives the product to rotate in all directions in a three-dimensional space, and further diversifying the functions of the supporting device.

As an example, referring to fig. 2 to fig. 5, the fixing assembly 220 includes a first limiting member 221, a penetrating portion 222 and a second limiting member 223, the penetrating portion 222 penetrates the rotating assembly 230, the first limiting member 221 is connected to the bottom end of the column body 210, the first limiting member 221 and the second limiting member 223 are respectively connected to two opposite ends of the penetrating portion 222 and respectively abut against two opposite sides of the rotating assembly 230; the second stopper 223 is screwed to the through-hole 222.

By providing the first limiting member 221, the penetrating portion 222, and the second limiting member 223, the first limiting member 221 and the second limiting member 223 can limit the rotating assembly 230 in the axial direction, so as to prevent the rotating assembly 230 from separating from the base assembly of the column module 200. In addition, the penetrating portion 222 and the second limiting member 223 are connected by a screw connection, so that not only the stable connection effect of the penetrating portion 222 and the second limiting member 223 can be realized, but also the penetrating portion 222 and the second limiting member 223 can be detached from each other, and the penetrating portion 222 penetrates through the rotating assembly 230, so that the fixing assembly 220 and the rotating assembly 230 can be installed conveniently. Furthermore, the penetrating portion 222 and the second limiting member 223 are connected by a screw, so that when the penetrating portion 222 is connected with the second limiting member 223, the screw can adjust the pre-tightening pressure between the second limiting member 223 and the rotating assembly 230, so as to adjust the friction between the second limiting member 223 and the rotating assembly 230, thereby adjusting the rotating force and the hand feeling when the user rotates the fixing assembly 220 or the rotating assembly 230, and the driving torque adjusting manner is simple and flexible. Specifically, when the screw connects the penetrating portion 222 and the second limiting member 223 more tightly, the pressing force of the second limiting member 223 on the rotating component 230 is larger, and the pressure between the rotating component 230 and the first limiting member 221 is also larger, so that the friction between the second limiting member 223 and the rotating component 230 is increased, the friction between the first limiting member 221 and the rotating component 230 is increased, the driving moment when the fixing component 220 rotates relative to the rotating component 230 is increased, the use hand feeling of a user is increased, and the effect that the fixing component 220 rotates relative to the rotating component 230 easily under an unexpected acting force is avoided. When the screw connects the penetrating portion 222 and the second limiting member 223 loosely, the pressing force of the second limiting member 223 on the rotating assembly 230 is smaller, and the pressing force between the rotating assembly 230 and the first limiting member 221 is also smaller, so that the friction between the second limiting member 223 and the rotating assembly 230 is reduced, the friction between the first limiting member 221 and the rotating assembly 230 is reduced, and the driving moment when the fixing assembly 220 rotates relative to the rotating assembly 230 is reduced, so that the user can easily rotate the fixing assembly 220 relative to the rotating assembly 230.

Further, an oil storage groove may be formed in one side of the rotating assembly 230 facing the second limiting member 223, so that when the fixing assembly 220 and the rotating assembly 230 rotate relatively, an effect of lubricating oil in the oil storage groove in one side of the rotating assembly 230 facing the second limiting member 223 can be achieved, and a friction force between the rotating assembly 230 and the second limiting member 223 is reduced; or an oil storage groove may be formed on one side of the rotating assembly 230 facing the first limiting member 221, so that when the fixing assembly 220 and the rotating assembly 230 rotate relatively, an effect of lubricating oil in the oil storage groove on one side of the rotating assembly 230 facing the first limiting member 221 is achieved, and a friction force between the rotating assembly 230 and the first limiting member 221 is reduced; or, oil storage grooves are formed in both the side of the rotating component 230 facing the first limiting member 221 and the side of the rotating component 230 facing the second limiting member 223, so that when the rotating component 230 and the fixing component 220 rotate relatively, the surface of the rotating component 230 opposite to the fixing component 220 has lubricating oil, friction between the rotating component 230 and the first limiting member 221 and between the rotating component 230 and the second limiting member 223 is reduced, the risk of seizure during rotation of the column module 200 is reduced, and the risk of damage to the bearing when the load is too large is also avoided. Of course, in other examples, the oil reservoir may be disposed on the inner wall of the rotating member 230 facing the through hole 222.

Further, referring to fig. 6 and 8, the bottom plate 100 has an exposing hole 101 for exposing the second limiting member 223.

Through the exposure hole 101 for exposing the second limiting member 223 on the chassis 100, the pretightening force between the second limiting member 223 and the rotating component 230 can be conveniently adjusted by the user through the exposure hole 101 without detaching the chassis 100, thereby facilitating the user operation and reducing the detaching process.

Further, the base plate 100 further has a mounting groove with an upward opening, the rotating assembly 230 may be installed in the mounting groove, and the exposure hole 101 communicates with the mounting groove and penetrates through a bottom wall of the mounting groove. By such arrangement, the upright module 200 is more stable to mount relative to the chassis 100, and the positioning effect of the rotating assembly 230 and the chassis 100 can be quickly realized, so that an operator can conveniently and quickly connect the rotating assembly 230 and the chassis 100.

Further, referring to fig. 5 to 9, a positioning post 240 is disposed at the bottom of the rotating assembly 230, the chassis 100 is provided with a positioning hole 102 and a connecting hole 103, the positioning post 240 is inserted into the positioning hole 102, and the rotating assembly 230 is connected to the chassis 100 by passing through the connecting hole 103 through a fastener 400; fastener 400 is disposed offset from the central axis of rotating assembly 230.

By inserting the positioning posts 240 disposed on the rotating assembly 230 into the positioning holes 102 of the chassis 100, the rotating assembly 230 and the chassis 100 do not relatively rotate to a large extent, so that a user can quickly align a connection position where the rotating assembly 230 needs to be fixedly connected with the chassis 100. That is, after the positioning column 240 is inserted into the positioning hole 102, the fastening member 400 is inserted through the connecting hole 103 of the chassis 100 to connect with the rotating assembly 230. By positioning the fastener 400 offset from the central axis of the rotating assembly 230, it is avoided that the rotating assembly 230 will rotate about the axis of the fastener 400 when only one fastener 400 is provided.

Further, as shown in fig. 8 and 9, only one fastener 400 is provided. Therefore, on the basis of ensuring the stable connection of the rotating assembly 230 and the chassis 100, the operation steps are simplified, and the installation efficiency of the rotating assembly 230 and the chassis 100 is improved. Fastener 400 may be a thumb screw. With the arrangement, a user can manually fasten the chassis 100 and the column module 200 without using tools such as a screwdriver, so that the operation steps are simplified, and the assembly efficiency of the base and the column module 200 is improved. In one example, the fastener 400 includes a body portion 410 and a pull ring 420, the body portion 410 passing through the connection hole 103; the handle ring 420 is hinged to the body 410, and a rotation axis of the handle ring 420 is perpendicular to an axis of the body 410. By hinging the handle ring 420 to the body 410 and making the rotation axis of the handle ring 420 perpendicular to the axis of the body 410, the user can hold the handle ring 420 and connect the chassis 100 and the upright module 200 together by using a knob when the chassis 100 and the upright module 200 need to be fastened together by using the fastener 400. In addition, after the user completes the fastening action through the fastening member 400, the handle ring 420 can be rotated to a position close to the bottom surface of the chassis 100, so that the risk that the chassis 100 is unstably placed due to the fact that the handle ring 420 abuts against the desktop when the chassis 100 is placed on the desktop is avoided. Further, the fastening member 400 is disposed near the positioning post 240, and the handle ring 420 is sleeved outside the positioning post 240 and abuts against one side of the positioning post 240 near the wide opening portion 1021. So set up, make handle ring 420 can overlap and locate outside reference column 240 for reference column 240 can play the restriction to the rotation of fastener 400, reduces the rotatory and emergence not hard up risk of fastener 400. In addition, the handle ring 420 is sleeved outside the positioning column 240 and abuts against one side of the limiting part 242 close to the wide part 1021, so that the handle ring 420 has a pulling force on the positioning column 240 in the direction from the wide part 1021 to the narrow part 1022, and can play a limiting effect on the positioning column 240, and the positioning column 240 is prevented from being separated from the narrow part 1022 and further separated from the chassis 100 through the wide part 1021.

Further, the handle ring 420 includes a rigid portion 421 and an elastic portion 422, the rigid portion 421 is hinged to the body portion 410; the elastic portion 422 is connected to the rigid portion 421 and elastically abuts against one side of the positioning post 240 close to the wide opening portion 1021.

By hinging the rigid portion 421 to the body portion 410, it is convenient for the user to rotate the entire fastener 400 by driving the rigid portion 421 and to connect the chassis 100 and the column module 200. As such, it is possible to improve the workability and stability with which the fastener 400 can connect the chassis 100 and the column module 200, thereby improving the efficiency of connecting the fastener 400 to the chassis 100 and the column module 200. Further, through connecting elastic part 422 in rigidity portion 421 to elasticity supports and holds one side that reference column 240 is close to wide mouthful portion 1021, makes handle ring 420 more stable to the taut effect of reference column 240, and still be convenient for handle ring 420 cover under elastic part 422's elastic action outside locating reference column 240, improves handle ring 420 cover and locates the outer efficiency of reference column 240.

Further, as shown in fig. 5, the positioning post 240 includes a main body section 241 and a limiting portion 242, the main body section 241 is connected to the rotating assembly 230, and the diameter of the limiting portion 242 is larger than that of the main body section 241; the positioning hole 102 includes a wide opening portion 1021 and a narrow opening portion 1022 which are mutually communicated, a hole diameter of the wide opening portion 1021 is larger than a hole diameter of the narrow opening portion 1022, the main body section 241 penetrates through the narrow opening portion 1022, and the limiting portion 242 abuts against a side of the chassis 100 which is away from the pillar body 210.

The aperture of the wide opening 1021 is larger than that of the narrow opening 1022, so that the main body section 241 and the limiting part 242 of the positioning column 240 can pass through the wide opening 1021, and then rotate until the main body section 241 of the positioning column 240 is inserted into the narrow opening 1022, and at this time, the limiting part 242 also rotates along with the main body section 241 and can abut against one side of the chassis 100 departing from the column module 200, thereby achieving the effect of positioning the positioning column 240 in the positioning hole 102. In the connection process, the chassis 100 and the column module 200 can be connected and are limited in the vertical direction only through two steps of insertion and rotation, and the effect of preventing the column module 200 from being separated from the chassis 100 can be achieved. The installation process is simple and rapid, installation time of operators is greatly saved, and installation efficiency is improved.

Furthermore, a plurality of positioning holes 102 and a plurality of positioning pillars 240 are correspondingly disposed, and the plurality of positioning holes 102 are distributed along the annular array.

It can be understood that when the positioning posts 240 adopt the translation motion scheme, the user needs to drive a specific position of the column module 200 (generally, the center position of the column module 200) to move the positioning posts 240 from the wide opening 1021 to the narrow opening 1022 synchronously. In the invention, the positioning holes 102 are distributed along the annular array, so that the positioning posts 240 need to rotate relative to the chassis 100 when moving from the wide opening 1021 to the narrow opening 1022, and in this scheme, no matter where the user drives the upright post module 200 to rotate the upright post module 200, each positioning post 240 can rotate simultaneously, and the rotation angles of the positioning posts 240 are more uniform, so that the installation efficiency and the installation stability are further improved.

Based on the scheme that the top end of the upright post body 210 is provided with the insertion groove 212a and the avoidance port 212b communicated with the insertion groove 212a, the insertion groove 212a and the avoidance port 212b communicated with the insertion groove 212a can be arranged at the top end of the upper movable upright post 212.

In another example, referring to fig. 15 and 16 in combination, the column body 210 includes a lower fixed column 211, an upper movable column 212, and a coil spring 213; the upper movable upright 212 is in sleeve fit with the lower fixed upright 211, so that the upper movable upright 212 can lift relative to the lower fixed upright 211; the coil spring 213 includes a stretching portion 2131 and a winding portion 2132, one end of the stretching portion 2131 is fixedly connected to the lower fixing column 211, and the other end extends downward; the winding portion 2132 is connected to the other end of the pulling portion 2131; the upper movable post 212 is inserted at least partially into the gap between the stretching portion 2131 and the winding portion 2132.

When the user's driving force is removed, the display may have two different movement trends due to the difference in the elastic force of the coil springs 213: 1. when the elastic force of the coil spring 213 is too small, after the driving force of the user is cancelled, the upper movable upright 212 drives the display device to have a downward sliding tendency, and at this time, it needs to be ensured that the sum of the upward friction force between the upper movable upright 212 and the lower fixed upright 211 and the elastic force of the coil spring 213 needs to be balanced with the self-gravity of the upper movable upright 212 and the product mounted on the upper movable upright 212, so as to achieve the effect that the upper movable upright 212 stops at any position. 2. When the elastic force of the coil spring 213 is too large, after the driving force of the user is cancelled, the upper movable upright 212 drives the display device to have a tendency of sliding upwards together, and at this time, it needs to be ensured that the sum of the downward friction force between the upper movable upright 212 and the lower fixed upright 211 and the self-gravity of the upper movable upright 212 and the product can be balanced with the elastic force of the coil spring 213, so as to achieve the effect that the upper movable upright 212 stops at any position.

In the present invention, only by inserting at least a part of the upper movable pillar 212 into the gap between the stretching portion 2131 and the winding portion 2132, a stable and effective lifting effect can be achieved while simplifying the components.

According to the technical scheme, the upper movable upright 212 is matched with the lower fixed upright 211 in a sleeved mode, so that the upper movable upright 212 and the lower fixed upright 211 can achieve a natural vertical guiding effect without guide structures such as sliding rails and the like, and the upper movable upright 212 can lift along the length direction of the lower fixed upright 211. In addition, by arranging the coil spring 213 in the lower fixed upright 211, the resultant force between the elastic force of the coil spring 213, the friction force between the upper movable upright 212 and the lower fixed upright 211, and the self-gravity of the upper movable upright 212 and the product is zero, so that the upper movable upright 212 can be lifted at any position in the stroke and can stay at any position. In addition, by inserting at least part of the upper movable upright 212 into the gap between the stretching portion 2131 and the winding portion 2132 of the coil spring 213, the pressure of the winding portion 2132 on the upper movable upright 212 can be increased in the process that the upper movable upright 212 slides downwards to drive the winding portion 2132 to extend, so that the pressure of the upper movable upright 212 on the stretching portion 2131 is increased, the arrangement of a support shaft for supporting the winding portion 2132 can be reduced, the risk that the winding portion 2132 of the coil spring 213 is pressed in the radial direction to deform is reduced, the upper movable upright 212 is more stable when driving the coil spring 213 to stretch and contract, the friction force between the upper movable upright 212 and the coil spring 213 is increased, and the pushing hand feeling of a user when driving the upper movable upright 212 to lift is improved.

In addition, the contact area of the side walls of the upper movable upright 212 and the lower fixed upright 211 is also reduced, so that the relative friction force of the upper movable upright 212 and the lower fixed upright 211 is reduced. By positioning the through slot 2112a in correspondence with the coil spring 213, the coil spring 213 can be inserted through the through slot 2112a into the lower fixing post 211 during installation to fixedly connect with the first side wall 2111 of the lower fixing post 211, thereby facilitating installation of the coil spring 213.
