DETAILED DESCRIPTION

[0047] It should be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order for the objects. It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0048] The following combination Figures 1 to 9 The supporting device described in the embodiments of the present application is described in detail.

[0049] The supporting device described in the embodiment of the present application includes: a fixing assembly 10, a cushion assembly 300 and a connecting body 400. The fixing assembly 10 has a receiving cavity; the clamping portion 220 of the fixing assembly 10 has an opening 230 communicating with the receiving cavity; the cushion assembly 300 is located in the receiving cavity; the cushion assembly 300 has a groove 310 facing the opening 230; the connecting body 400 includes: a ball head 410 and a rod 420 connected to the ball head 410; part of the ball head 410 is located in the groove 310, and the ball head 410 is sandwiched between the cushion assembly 300 and the clamping portion 220; the rod 420 passes through the opening 230 and is located outside the receiving cavity.

[0050] In the embodiment of the present application, the rod 420 is used to connect with the external device to be supported so as to support the device to be supported by the support device; the rod 420 can move relative to the opening 230. At this time, the position of the rod 420 relative to the fixed component 10 can be adjusted by moving the rod 420 relative to the opening 230, thereby adjusting the angle at which the support device supports the device to be supported. At the same time, since the ball head 410 is sandwiched between the cushion block assembly 300 and the clamping portion 220, at this time, the cushion block assembly 300 and the clamping portion 220 can provide a damping force for the ball head 410 to rotate, so that the ball head 410 and the rod 420 of the connector 400 can be located at a specific stable position relative to the fixed component 10. Here, the structure of the device to be supported is not limited. For example, the device to be supported may include an electronic device. As an example, the device to be supported may include a mobile phone, a camera, a camera, etc.

[0051] In the embodiment of the present application, the first clamping force F1 provided by the block assembly 300 to the ball head 410 is greater than the second clamping force F provided by the clamping portion 220 to the ball head 410, and the block assembly 300 provides a friction force to the ball head 410 equal to F1×u; wherein u is the friction coefficient between the block assembly 300 and the ball head 410; the first clamping force F1 is the positive pressure provided by the block assembly 300 to the ball head 410; since the first clamping force F1 provided by the block assembly 300 to the ball head 410 is relatively large, the block assembly 300 can provide a larger damping force to the ball head 410, and the connector 400 can support a heavier device to be supported.

[0052] In the related art, the support structure includes: a pad structure 910, a clamping structure and a ball head structure 920. The pad structure 910 and the clamping structure clamp the ball head structure 920 to fix the relative position of the ball head structure 920. However, since the pad structure 910 and the clamping structure provide the same clamping force to the ball head structure 920, for example, Fig. 9As shown, the clamping force provided by the clamping structure to the ball head structure 920 is N1, and the clamping force provided by the pad structure 910 to the ball head structure 920 is N2, N1=N2; at this time, the clamping force N2 provided by the pad structure 910 to the ball head structure 920 is relatively small, and the friction force provided by the pad structure 910 to the ball head structure 920 is also relatively small, so that the weight of the object supported by the support structure is also small. In the support device of the present application, since the first clamping force F1 provided by the pad assembly 300 to the ball head 410 is greater than the second clamping force F provided by the clamping part 220 to the ball head 410, the pad assembly 300 can provide a larger damping force for the ball head 410, and then the connector 400 can support a heavier device to be supported.

[0053] In the embodiment of the present application, the implementation method of the first clamping force F1 provided by the pad assembly 300 to the ball head 410 is greater than the second clamping force F provided by the clamping portion 220 to the ball head 410 is not limited. For example, the first clamping force F1 provided by the pad assembly 300 to the ball head 410 can be made greater than the second clamping force F provided by the clamping portion 220 to the ball head 410 by increasing the roughness of the contact area between the pad assembly 300 and the ball head 410. For another example, the first clamping force F1 provided by the pad assembly 300 to the ball head 410 can be made greater than the second clamping force F provided by the clamping portion 220 to the ball head 410 by increasing the roughness of the contact area between the ball head 410 and the pad assembly 300.

[0054] For example, Figure 3 and Figure 5 As shown, the block assembly 300 may include an inclined side surface 301 located on the circumferential side of the groove 310, and the inclined side surface 301 is tangent to the spherical surface of the ball head 410; at this time, the first clamping force F1 passes through the center of the ball head 410 and is perpendicular to the inclined side surface 301; the first clamping force F1 and the second clamping force F are not on the same straight line. When the block assembly 300 is an annular structure, the second clamping force F provided by the clamping portion 220 to the ball head 410 can pass through the first axis 350 of the block assembly 300; here, the first clamping force F1 is the positive pressure applied to the ball head 410 by the inclined side surface 301. In order to balance the second clamping force F, the positive pressure applied to the ball head 410 by the inclined side surface 301 is relatively large, so that the friction provided by the block assembly 300 can be increased through the inclined side surface 301; and then the heavier equipment to be supported can be supported through the connector 400.

[0055] In related technologies, such as Fig. 9As shown, the ball head structure 920 contacts the bottom of the pad structure 910. At this time, the bottom of the pad structure 910 will balance a part of the clamping force N1 provided by the clamping structure to the ball head structure 920, so that the positive pressure provided by the circumferential side of the pad structure 910 to the ball head structure 920 is greatly reduced, and the positive pressure provided by the pad structure 910 to the ball head structure 920 is N2, N2=N1; at this time, the friction force provided by the pad structure 910 to the ball head structure 920 is N1×u1; wherein u1 is the friction coefficient between the pad structure 910 and the ball head structure 920; since the positive pressure N2 provided by the pad structure 910 to the ball head structure 920 is equal to the clamping force N1 provided by the clamping structure to the ball head structure 920, the friction force provided by the pad structure 910 to the ball head structure 920 is also smaller, thereby making the weight of the object that the support structure can support smaller. In the support device of the present application, since the first clamping force F1 is the positive pressure applied by the inclined side 301 to the ball head 410, in order to balance the second clamping force F, the positive pressure applied by the inclined side 301 to the ball head 410 is relatively large, so that the friction force provided by the cushion block assembly 300 can be increased through the inclined side 301; and then the heavier equipment to be supported can be supported through the connecting body 400.

[0056] like Figure 2 and Figure 5 As shown, the bottom of the groove 310 is spaced apart from the ball head 410 , that is, the ball head 410 is mainly supported by the inclined side surface 301 of the cushion block assembly 300 so as to provide a larger rotation damping force through the inclined side surface 301 .

[0057] like Figure 4 and Figure 3 As shown, the pad assembly 300 may also include a bottom side plane 340; the minimum first angle a between the inclined side surface 301 and the bottom side plane 340 may be greater than 0 degrees and less than 90 degrees, so that the pad assembly 300 contacts the ball head 410 through the inclined side surface 301. It should be noted that a larger angle and a smaller angle are generally formed between the plane where the inclined side surface 301 is located and the plane where the bottom side plane 340 is located, and the minimum first angle a refers to the smaller angle formed between the plane where the inclined side surface 301 is located and the plane where the bottom side plane 340 is located. When the first angle a between the inclined side surface 301 and the bottom side plane 340 is larger, the first clamping force F1 provided by the inclined side surface 301 to the ball head 410 is larger. As an example, the first angle a may be greater than or equal to 60 degrees and less than 90 degrees, so as to further increase the first clamping force F1 provided by the inclined side surface 301 to the ball head 410, thereby supporting a heavier device to be supported through the connector 400. In one application, the first angle a may be 60 degrees.

[0058] The pad assembly 300 can be arranged in an annular shape, and the second clamping force F provides the second clamping force F to the ball head 410 along the first direction. The first direction can pass through the first axis 350 of the pad assembly 300, and the first direction can be perpendicular to the bottom plane 340. The first axis 350 of the pad assembly 300 can be perpendicular to the bottom plane 340. Of course, in other examples, the pad assembly 300 may not include the bottom plane 340. In this case, the minimum second angle b between the inclined side 301 and the first axis 350 of the pad assembly 300 can be greater than 0 degrees and less than 90 degrees. As an example, the second angle b can be greater than 0 degrees and less than 30 degrees. As an example, the second angle b can be 30 degrees. It should be noted that the second angle b+the first angle a=90 degrees. Here, the first axis 350 of the pad assembly 300 is also the axis of the groove 310.

[0059] As an example, the groove 310 may be trumpet-shaped, with the large opening of the groove 310 facing the clamping portion 220, so that part of the ball head 410 is located in the groove 310 through the large opening of the groove 310, and the trumpet-shaped groove 310 is easy to process. Of course, the groove 310 may not be trumpet-shaped, as long as the surface where the groove 310 contacts the ball head 410 is the inclined side surface 301. In one application, the corresponding part of the groove 310 and the ball head 410 is trumpet-shaped.

[0060] like Figure 4 and Figure 3 As shown, the pad assembly 300 includes an inclined side surface 301 and a bottom side plane 340, and the inclined side surface 301 is in contact with the ball head 410; the rotation damping force provided by the pad assembly 300 to the ball head 410 is: Wherein, F is the second clamping force F of the clamping portion 220 clamping the ball head 410 along the first direction, a is the minimum first angle a between the inclined side surface 301 of the cushion block assembly 300 and the bottom side plane 340 of the cushion block assembly 300, and u is the friction coefficient between the inclined side surface 301 and the ball head 410. Here, it is assumed that the inclined side surface 301 provides two positive pressures to the ball head 410, and the two positive pressures are F2 and F3; the rotation damping force provided by the inclined side surface 301 of the cushion block assembly 300 to the ball head 410 is: F2×u+F3×u=(F2+F3)×u=F1×u; wherein, F1 is the first clamping force provided by the cushion block assembly 300 to the ball head 410; due to The rotation damping force provided by the inclined side surface 301 of the cushion block assembly 300 to the ball head 410 is: Wherein, F is the second clamping force of the clamping portion 220 clamping the ball head 410 along the first direction; since the first angle a can be greater than 0 degrees and less than 90 degrees, the value of cosa is greater than 0 and less than 1, so that the rotation damping force provided to the ball head 410 by the inclined side surface 301 of the pad assembly 300 is greatly increased. As an example, the first angle a is 60 degrees, and cosa is 0.5. At this time, the rotation damping force provided to the ball head 410 by the inclined side surface 301 of the pad assembly 300 is: 2×F×u; as another example, the first angle a is arccos(1 / 3), that is, the first angle a is approximately equal to 70.53 degrees, and cosa is 1 / 3. At this time, the rotation damping force provided to the ball head 410 by the inclined side surface 301 of the pad assembly 300 is: 3×F×u. As another example, the first angle a is arccos(1 / 4), that is, the first angle a is approximately equal to 75.52 degrees, and cosa is 1 / 4. At this time, the rotation damping force provided by the inclined side surface 301 of the cushion block assembly 300 to the ball head 410 is: 4×F×u. Here, when the first angle is greater than or equal to 60 degrees and less than 90 degrees, the first clamping force provided by the cushion block assembly to the ball head is more than twice the second clamping force provided by the clamping portion to the ball head. When the friction coefficient between the pad assembly 300 and the ball head 410 is the same as the friction coefficient between the clamping portion 220 and the ball head 410, the rotation damping force provided by the inclined side surface 301 of the pad assembly 300 to the ball head 410 is 2, 3 or 4 times the rotation damping force provided by the clamping portion 220 to the ball head 410; thus, the damping force of the rotation of the ball head 410 can be greatly increased by the inclined side surface 301, and the connecting body 400 can support heavier equipment to be supported. It should be noted that the above description is based on the assumption that the inclined side surface 301 provides two positive pressures to the ball head 410. The algorithm for the inclined side surface 301 to provide more than two positive pressures to the ball head 410 is similar to the algorithm for the above two positive pressures, which will not be repeated here.

[0061] In other examples, the rotational damping force provided by the cushion block assembly 300 to the ball head 410 can also be increased by increasing the roughness of the contact area between the cushion block assembly 300 and the ball head 410. Alternatively, the rotational damping force provided by the cushion block assembly 300 to the ball head 410 can also be increased by increasing the roughness of the contact area between the ball head 410 and the cushion block assembly 300.

[0062] like Figure 4 and Figure 3 As shown, the rotation damping force provided by the cushion block assembly 300 to the ball head 410 can also be: Wherein, F is the second clamping force of the clamping portion 220 clamping the ball head 410 along the first direction, b is the second angle b between the inclined side surface 301 and the axis of the groove 310, and u is the friction coefficient.

[0063] like Figure 4 and Figure 3 As shown, the pad assembly 300 can be arranged in a ring shape, and the intersection of the plane passing through the first axis 350 of the pad assembly 300 and the inclined side surface 301 can be a straight line; at this time, the first angle a between the inclined side surface 301 and the bottom side plane 340 is a fixed value, even if there is a manufacturing error in the size of the ball head 410, the rotational damping force provided by the inclined side surface 301 to the ball head 410 is generally a fixed value, and will not change with the change of the size of the ball head 410, and there is no need to consider the size of the ball head 410, thereby greatly improving the adaptability of the support device; at the same time, since the rotational damping force provided by the inclined side surface 301 to the ball head 410 is generally a fixed value, the maximum supporting force provided by the support device for the supported equipment is also generally a fixed value, thereby greatly improving the stability of the maximum supporting force provided by the support device, that is, the maximum supporting force provided by the support device is generally a fixed value; there will be no situation where the maximum supporting force provided by some support devices is larger and the maximum supporting force provided by some support devices is smaller due to manufacturing errors in the size of the ball head 410.

[0064] like Figure 4 and Figure 3 As shown, the pad assembly 300 can be arranged in a ring shape, and the cross-section formed by the plane of the first axis 350 of the pad assembly 300 and the pad assembly 300 can include a trapezoidal portion, and the inclined side 301 forms the first side 301 of the trapezoidal portion, and the second side 302 of the trapezoidal portion contacts the inner wall of the accommodating cavity; the straight first side 301 can make the rotational damping force provided by the pad assembly 300 more stable, and the second side 302 of the trapezoidal portion contacts the inner wall of the accommodating cavity, which can prevent the inclined side 301 from relative movement or change, thereby further improving the stability of the rotational damping force provided by the pad assembly 300.

[0065] like Figure 2 As shown, the outer side surface of the wall of the groove 310 formed by the cushion block assembly 300 contacts the inner wall of the accommodating cavity to define the shape of the groove 310. By contacting the outer side surface of the wall of the groove 310 with the inner wall of the accommodating cavity, the cushion block assembly 300 can be prevented from moving or deforming, thereby further improving the stability of the rotational damping force provided by the cushion block assembly 300.

[0066] Of course, in other implementations, the pad assembly 300 may also include an inclined concave arc surface or an inclined convex arc surface located on the peripheral side of the groove 310, and the bottom of the groove 310 is spaced apart from the ball head 410; at this time, since the ball head 410 is not supported by the bottom of the groove 310, the first clamping force F1 provided by the inclined concave arc surface or the inclined convex arc surface on the peripheral side of the groove 310 to the ball head 410 is also greater than the second clamping force F provided by the clamping portion 220 to the ball head 410, so that the pad assembly 300 can also provide a larger damping force for the ball head 410, and then the connecting body 400 can support a heavier device to be supported.

[0067] In the embodiment of the present application, the structure of the fixing assembly 10 is not limited.

[0068] For example, Figure 2 and Figure 8 As shown, the fixing assembly 10 may include: a base body 100 and a fixing body 200, the fixing body 200 and the base body 100 jointly defining a receiving cavity; the clamping portion 220 of the fixing body 200 has an opening 230 connected to the receiving cavity; the fixing portion 210 of the fixing body 200 is movably connected to the base body 100 in the second direction C; the second direction C is a direction formed between the clamping portion 220 and the fixing portion 210, and the position of the connecting body 400 relative to the fixing assembly 10 can be conveniently adjusted by movably connecting the fixing portion 210 of the fixing body 200 to the base body 100 in the second direction C. As an example, when the rod portion 420 needs to be adjusted from the current position to the target position relative to the opening 230, the fixing portion 210 can be first moved in the second direction C relative to the base body 100 to reduce the clamping force of the cushion block assembly 300 and the clamping portion 220 clamping the ball head 410, and then a smaller force can be used to move the rod portion 420 from the current position to the target position. After the rod portion 420 moves to the target position, the fixing portion 210 is moved in the second direction C relative to the base body 100 to increase the clamping force of the cushion block assembly 300 and the clamping portion 220 clamping the ball head 410, thereby allowing the rod portion 420 to stably support the device to be supported at the target position.

[0069] In this example, the clamping portion 220 has a first clamping force F1 in a first direction on the ball head 410, wherein the first direction and the second direction C may be parallel; so that the clamping force of the cushion block assembly 300 and the clamping portion 220 clamping the ball head 410 can be quickly adjusted by moving the fixing portion 210 and the seat body 100 in the second direction C. Of course, in other examples, the first direction and the second direction C may not be parallel, and in this case, the angle between the first direction and the second direction C may be less than 90 degrees.

[0070] In this example, if Figure 2As shown, the clamping portion 220 may have a first spherical surface 250 that matches the ball head 410; the first spherical surface 250 exerts a second clamping force F in a first direction on the ball head 410, and the first spherical surface 250 is in contact with the ball head 410, so that the clamping portion 220 can provide a more stable first clamping force F1 to the ball head 410. Of course, in other examples, the clamping portion 220 may also be in contact with the ball head 410 through a non-spherical surface. As an example, the clamping portion 220 may be in contact with the ball head 410 through a horn-shaped surface, and the horn-shaped surface exerts a first clamping force F1 in a first direction on the ball head 410.

[0071] In this example, if Figure 2 As shown, the outer peripheral side of the seat body 100 has a first threaded structure 140, and the outer peripheral side of the fixing part 210 of the fixing body 200 has a flange 260; the supporting device may also include: a fastener 540, the fastener 540 is sleeved outside the fixing part 210 and the first threaded structure 140; the fastener 540 has a clamping platform 541 pressed on one side of the flange 260, and has a second threaded structure 542 that cooperates with the first threaded structure 140; when the fastener 540 is rotated, the fixing part 210 and the seat body 100 can be moved in the second direction C, thereby adjusting the clamping force of the clamping part 220 and the pad assembly 300 to clamp the ball head 410. Of course, in other examples, the fastener 540 and the fixing body 200 may also be a structural component. In this case, the fastener 540 and the fixing body 200 may be rotated as a whole to move the fixing portion 210 and the seat body 100 in the second direction C, thereby adjusting the clamping force of the clamping portion 220 and the pad assembly 300 to clamp the ball head 410.

[0072] In this example, if Figure 2 As shown, the fixing body 200 may have a receiving space and a mounting opening 240 located on the side of the fixing portion 210; the seat body 100 may include: a seat portion 110 and a support portion 120. The seat portion 110 and the fixing portion 210 are movably connected in the second direction C; the support portion 120 passes through the mounting opening 240 and is located in the receiving space, and defines a receiving cavity with the fixing body 200; when the seat portion 110 and the fixing portion 210 move in the second direction C, the size of the receiving cavity in the second direction C is adjusted, and the clamping force of the cushion block assembly 300 and the clamping portion 220 clamping the ball head 410 is adjusted.

[0073] Here, the seat 110 may have a second connection structure for connecting with a carrier; the form of the second connection structure is not limited. For example, the second connection structure may be a buckle structure, a threaded structure, a connection hole structure, etc., for connecting the seat 110 with the carrier. The carrier refers to a structure that carries the support device, for example, the carrier may be a wall, a bookshelf, a table, etc.

[0074] Here, the implementation manner of movably connecting the seat portion 110 and the fixing portion 210 in the second direction C is similar to the implementation manner of movably connecting the seat body 100 and the fixing portion 210 in the second direction C described above, and will not be repeated here.

[0075] In the embodiments of the present application, Figure 7 As shown, the clamping portion 220 can be hemispherical, the first part 231 of the opening can be located at the end of the clamping portion 220, and the second part 232 of the opening can extend from the end of the clamping portion 220 to the side of the fixing portion 210 of the fixing body 200, so that the support angle of the device to be supported connected to the rod portion 420 can be adjusted by moving the rod portion 420 between the first part 231 of the opening and the second part 232 of the opening.

[0076] Here, the rod 420 may have a third connection structure for connecting to the device to be supported; the form of the third connection structure is not limited. For example, the third connection structure may be a buckle structure, a threaded structure, a connection hole structure, etc. for connecting the rod 420 to the device to be supported. As an example, Figure 7 As shown, the end of the rod 420 located outside the accommodating cavity has a third threaded structure 421, and the rod 420 is connected to the device to be supported through the third threaded structure 421; here, the supporting device can also include: a second connecting member 520, the second connecting member 520 is similar to a nut structure, and the second connecting member 520 is matched with the third threaded structure 421 to connect to the device to be supported.

[0077] In some optional implementations of the embodiments of the present application, the support device may further include a first connection structure 600, which is disposed between the cushion block assembly 300 and the fixing assembly 10 to fix the position of the cushion block assembly 300 in the accommodating cavity.

[0078] In the related art, the position of the pad structure 910 in the accommodating cavity is not fixed, and there are often manufacturing errors between the pad structure 910 and the cavity in which the pad structure 910 is set. At this time, there is a gap between at least part of the pad structure 910 and the cavity in which the pad structure 910 is set; when the ball head structure 920 supports a heavier object and rotates relative to the pad structure 910, the pad structure 910 will move in the cavity, so that the pad structure 910 cannot stably provide rotational damping force. In the support device of the present application, the first connecting structure 600 is arranged between the pad assembly 300 and the fixing assembly 10 to fix the position of the pad assembly 300 in the accommodating cavity. The first connecting structure 600 can prevent the pad assembly 300 from moving in the accommodating cavity, so that the pad assembly 300 can provide a stable rotational damping force for the ball head 410, thereby enabling the support device to support heavier objects and improve the reliability of the support device.

[0079] In this implementation, the structure of the first connection structure 600 is not limited. For example, the first connection structure 600 may include a colloid structure. As an example, during the installation of the support device, the colloid structure may be disposed between the cushion block assembly 300 and the fixing assembly 10. For another example, the first connection structure 600 may include a threaded structure or a buckle structure.

[0080] In this implementation, when the fixing assembly 10 includes: a seat body 100 and a fixing body 200 , the first connecting structure 600 may be disposed between the cushion block assembly 300 and the seat body 100 .

[0081] like Figure 2 As shown, the first connection structure 600 may include: a first connection hole 330, a second connection hole 130 and a first connection member 510. The first connection hole 330 is arranged at the bottom of the groove 310; the second connection hole 130 is arranged at a position of the seat body 100 corresponding to the first connection hole 330; the first connection member 510 passes through the first connection hole 330 and is connected to the second connection hole 130; thus, the pad assembly 300 is fixed to the seat body 100 through the first connection hole 330, the second connection hole 130 and the first connection member 510.

[0082] Here, the first connection hole 330 may be a light hole or a threaded hole, and the second connection hole 130 may be a light hole or a threaded hole. The first connection member 510 may be a bolt or a screw. When both the first connection hole 330 and the second connection hole 130 are light holes, the first connection structure 600 may further include a nut, which may be connected to the threaded structure of the first connection member 510.

[0083] Here, if Figure 6 As shown, the wall of the seat body 100 located on the side of the second connection hole 130 can also be inserted into the first connection hole 330, so as to limit the position of the cushion block assembly 300 by the wall of the second connection hole 130, and prevent the cushion block assembly 300 from moving relative to the first connection member 510 in the radial direction; here, the first connection member 510 is used to prevent the cushion block assembly 300 from moving relative to the first connection member 510 in the axial direction. Of course, in other examples, the wall of the seat body 100 located on the side of the second connection hole 130 may not be inserted into the first connection hole 330.

[0084] Here, the cushion block assembly 300 may be arranged in a ring shape, and the axis of the cushion block assembly 300 may be colinear with the axis of the first connecting hole 330 ; so as to provide a stable fixing force for each peripheral area of ​​the cushion block assembly 300 through the first connecting member 510 .

[0085] In this implementation, the bottom of the groove 310 is spaced apart from the ball head 410; the outer peripheral side surface of the wall of the groove 310 formed by the cushion block assembly 300 contacts the inner wall of the accommodating cavity to limit the shape of the groove 310 and prevent the groove 310 from deforming, thereby enabling the cushion block assembly 300 to provide a stable rotational damping force for the ball head 410 through the shape-stable groove 310.

[0086] In this implementation, the pad assembly 300 may include at least two pad units 320; at least two pad units 320 define a groove 310; at least two pad units 320 are in contact with the inner wall of the accommodating cavity on one side facing away from the groove 310; the inner wall of the accommodating cavity blocks the at least two pad units 320, thereby preventing the at least two pad units 320 from moving toward the inner wall of the accommodating cavity or deforming, thereby ensuring that the shape and position of the groove 310 are stable by at least two pad units 320 being in contact with the inner wall of the accommodating cavity on one side facing away from the groove 310, so that the at least two pad units 320 can provide a stable rotational damping force for the ball head 410.

[0087] Here, the first connection structure 600 is disposed between at least two pad monomers 320 and the fixing assembly 10, so as to fix the positions of the at least two pad monomers 320 in the accommodating cavity. By fixing the positions of the at least two pad monomers 320 in the accommodating cavity through the first connection structure 600, the at least two pad monomers 320 can be prevented from moving in the accommodating cavity. For example, the first connection structure 600 can prevent each pad monomer 320 from moving toward the axis side of the groove 310; thus, the connection structure can greatly improve the stability of the shape and position of the groove 310, thereby greatly improving the stability of the rotation damping force provided by the at least two pad monomers 320 to the ball head 410.

[0088] In this implementation, a positioning structure 530 may be provided between at least two cushion block units 320 and the seat body 100 of the fixing assembly 10 to limit the positions of the at least two cushion block units 320 relative to the seat body 100; when assembling at least two cushion block units 320, the positioning structure 530 can enable the at least two cushion block units 320 to be quickly assembled into place, thereby greatly improving the assembly speed of the support device.

[0089] Here, the form of the positioning structure 530 is not limited. For example, the positioning structure 530 may include: a limiting groove 531 and a limiting protrusion 532. The limiting groove 531 may be arranged in an annular shape; the limiting protrusion 532 may be arranged in an annular shape and inserted into the limiting groove 531; one of the limiting groove 531 and the limiting protrusion 532 is arranged in at least two cushion block monomers 320, and the other of the limiting groove 531 and the limiting protrusion 532 is arranged in the seat body 100; thus, by inserting the limiting protrusion 532 into the limiting groove 531, at least two cushion block monomers 320 can be quickly assembled into place.

[0090] As an example, Figure 2 As shown, the limiting protrusion 532 is arranged on the supporting portion 120 of the seat body 100, and the limiting groove 531 is arranged on at least two cushion block units 320; here, each cushion block unit 320 is provided with a part of the limiting groove 531, so that each cushion block unit 320 can be quickly assembled into place through the cooperation between a part of the limiting groove 531 and the limiting protrusion 532.

[0091] Here, at least two cushion block monomers 320 may be arranged in an annular shape, and the axes of at least two cushion block monomers 320 may be collinear with the axes of the limiting protrusions 532 or the limiting grooves 531, so that at least two cushion block monomers 320 are arranged in an annular shape by inserting the limiting protrusions 532 into the limiting grooves 531. Of course, in some other examples, the cushion block assembly 300 may be a structural member, in which case the axes of the cushion block assembly 300 may also be collinear with the axes of the limiting protrusions 532 or the limiting grooves 531.

[0092] It should be noted that in some other examples, the limiting groove 531 and the limiting protrusion 532 may not be arranged in a ring shape.

[0093] The number of the at least two cushion block units 320 is not limited. For example, the cushion block assembly 300 may include three or four cushion block units 320; and the three or four cushion block units 320 may be arranged in a ring shape.

[0094] In some optional implementations of the embodiments of the present application, such as Figure 1 As shown, the cushion block assembly 300 may include at least two cushion block units 320, the at least two cushion block units 320 define a groove 310, and the sides of the at least two cushion block units 320 facing away from the groove 310 are respectively in contact with the inner wall of the accommodation cavity, as shown in FIG. Figure 2 shown.

[0095] In the related art, the pad structure 910 is an integral structure, and there are often manufacturing errors between the pad structure 910 and the cavity in which the pad structure 910 is set. At this time, there is a gap between at least part of the pad structure 910 and the cavity in which the pad structure 910 is set; for example, when the first side of the pad structure 910 is brought into contact with the wall of the cavity in which the pad structure 910 is set, there is a gap between the other side of the pad structure 910 opposite to the first side and the wall of the cavity in which the pad structure 910 is set; when the ball head structure 920 supports a heavier object and rotates relative to the pad structure 910, the pad structure 910 will move or deform toward the side with the gap in the cavity, thereby making it impossible for the pad structure 910 to stably provide rotational damping force. In the support device of the present application, the pad assembly 300 includes at least two pad units 320, and the at least two pad units 320 define a groove 310. The sides of the at least two pad units 320 facing away from the groove 310 are respectively in contact with the inner wall of the accommodating cavity. The inner wall of the accommodating cavity blocks the at least two pad units 320, thereby preventing the at least two pad units 320 from moving toward the inner wall of the accommodating cavity or deforming. Thus, the shape and position of the groove 310 are ensured to be stable by the sides of the at least two pad units 320 facing away from the groove 310 being in contact with the inner wall of the accommodating cavity, so that the at least two pad units 320 can provide a stable rotational damping force for the ball head 410, thereby enabling the support device to support heavier objects and improve the reliability of the support device.

[0096] In this implementation, the support device may also include a first connecting structure 600, which is arranged between at least two cushion block units 320 and the fixing assembly 10 to fix the positions of at least two cushion block units 320 in the accommodating cavity; by fixing the positions of at least two cushion block units 320 in the accommodating cavity through the first connecting structure 600, the at least two cushion block units 320 can be prevented from moving in the accommodating cavity. For example, the first connecting structure 600 can prevent each cushion block unit 320 from moving toward the axial side of the groove 310; thereby, the first connecting structure 600 can greatly improve the stability of the shape and position of the groove 310, thereby greatly improving the stability of the rotational damping force provided by at least two cushion block units 320 to the ball head 410.

[0097] The structure of the first connection structure 600 is not limited. For example, the first connection structure 600 may include a colloid structure. As an example, during the installation of the support device, the side of at least two pad block monomers 320 facing away from the groove 310 may be respectively in contact with the inner wall of the accommodating cavity, and then the colloid structure is arranged between the at least two pad block monomers 320 and the fixing assembly 10. For another example, the first connection structure 600 may include a threaded structure or a snap-fit ​​structure.

[0098] In this implementation, when the fixing assembly 10 includes: a base 100 and a fixing body 200, the first connecting structure 600 may be disposed between at least two cushion block units 320 and the base 100.

[0099] like Figure 1 As shown, the first connection structure 600 includes: a first connection hole 330, a second connection hole 130 and a first connection member 510 defined by at least two cushion block units 320 at the bottom of the groove 310; the second connection hole 130 is arranged at a position of the seat body 100 corresponding to the first connection hole 330; the first connection member 510 passes through the first connection hole 330 and is connected to the second connection hole 130; thereby, each of the at least two cushion block units 320 is fixed to the seat body 100 through the first connection hole 330, the second connection hole 130 and the first connection member 510.

[0100] The first connection hole 330 , the second connection hole 130 and the first connection member 510 have been described in the above embodiment, and will not be repeated here.

[0101] In this implementation, at least two gasket units 320 may be arranged in a ring shape, and the axes of at least two gasket units 320 may be colinear with the axis of the first connecting hole 330 ; so that a stable fixing force can be provided to each gasket unit 320 through the first connecting member 510 .

[0102] In the present implementation, a positioning structure 530 is provided between at least two cushion block units 320 and the seat body 100 to limit the positions of the at least two cushion block units 320 relative to the seat body 100; when assembling at least two cushion block units 320, the positioning structure 530 can enable each of the at least two cushion block units 320 to be quickly assembled into place, thereby greatly improving the assembly speed of the support device.

[0103] Here, the form of the positioning structure 530 is not limited. For example, the positioning structure 530 may include: a limiting groove 531 and a limiting protrusion 532. The limiting groove 531 may be arranged in an annular shape; the limiting protrusion 532 may be arranged in an annular shape and inserted into the limiting groove 531; one of the limiting groove 531 and the limiting protrusion 532 is arranged in at least two cushion block monomers 320, and the other of the limiting groove 531 and the limiting protrusion 532 is arranged in the seat body 100; thus, by inserting the limiting protrusion 532 into the limiting groove 531, at least two cushion block monomers 320 can be quickly assembled into place.

[0104] As an example, Figure 2As shown, the limiting protrusion 532 is arranged on the supporting portion 120 of the seat body 100, and the limiting groove 531 is arranged on at least two cushion block units 320; here, each cushion block unit 320 is provided with a part of the limiting groove 531, so that each cushion block unit 320 can be quickly assembled into place through the cooperation between a part of the limiting groove 531 and the limiting protrusion 532.

[0105] Here, at least two cushion block monomers 320 may be arranged in an annular shape, and the axes of at least two cushion block monomers 320 may be collinear with the axes of the limiting protrusions 532 or the limiting grooves 531, so that at least two cushion block monomers 320 are arranged in an annular shape by inserting the limiting protrusions 532 into the limiting grooves 531. Of course, in some other examples, the cushion block assembly 300 may be a structural member, in which case the axes of the cushion block assembly 300 may also be collinear with the axes of the limiting protrusions 532 or the limiting grooves 531.

[0106] It should be noted that in some other examples, the limiting groove 531 and the limiting protrusion 532 may not be arranged in a ring shape.

[0107] In this implementation, the number of the at least two cushion block units 320 is not limited. For example, the cushion block assembly 300 includes three or four cushion block units 320; the three or four cushion block units 320 are arranged in a ring shape.
