Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

It should be noted that the supporting device of the embodiment of the present invention is generally used for supporting a television, the supporting frame 10 is installed on a wall surface waiting for installation, and the television is installed on the turning bracket 20, so that the turning bracket 20 can be rotated to switch between horizontal and vertical screens of the television, so as to improve the experience of the user.

It should be noted that, in the embodiment of the present invention, the bracket body 21 is switched from the longitudinal position to the transverse position, that is, the television is switched from the transverse screen to the vertical screen.

It should be noted that, in the embodiment of the present invention, the first locking member slides along the extending track of the first distance-changing groove section 121, and then slides along the extending track of the first distance-changing groove section 122, that is, the first locking member can move in the vertical plane.

It should be noted that the supporting device of the embodiment of the present invention is not only suitable for an off-center tv set, but also suitable for a tv set with a center of gravity.

The inventor knows a supporting device which realizes the slow descending effect in the rotation process of the eccentric television by increasing the number of friction gaskets and increasing the locking torsion of the friction gaskets. However, this method requires a large frictional resistance to the rotation, which results in a very large resistance to the rotation of the tv set at the beginning of the rotation, thereby reducing the experience of the user.

Accordingly, as shown in fig. 1, 3, 4 and 5, the first embodiment of the present invention provides a supporting device. The support device includes a support frame 10, a steering bracket 20, an auxiliary rotating structure, and a first locking structure 30. The supporting frame 10 is connected with a foundation to be installed, the supporting frame 10 comprises a supporting body 11 and a first long groove 12 arranged on the supporting body 11, and the first long groove 12 comprises a first distance groove section 121 and a first variable distance groove section 122 connected with the first distance groove section 121; the steering bracket 20 comprises a bracket body 21 and a second long groove 22 arranged on the bracket body 21, wherein the extending direction of the first distance groove section 121 and the extending direction of the first distance-variable groove section 122 are respectively arranged to form an included angle with the extending direction of the second long groove 22; the auxiliary rotating structure is arranged on the support body 11 and the bracket body 21 and is used for pivotally connecting the bracket body 21 with the support body 11; wherein the first elongated slot 12 extends around a pivot point between the bracket body 21 and the support body 11, and the bracket body 21 has at least a longitudinal position and a transverse position; first locking structure 30 wears to locate first rectangular groove 12 and second rectangular groove 22, first locking structure 30 and support body 21 butt, and first locking structure 30 and second rectangular groove 22 sliding fit, first locking structure 30 and first rectangular groove 12 sliding fit, when first locking structure 30 slides in first gauge channel section 121, the distance between the axis of first locking structure 30 and the pivot point is unchangeable, when first locking structure 30 slides in first displacement channel section 122, the distance between the axis of first locking structure 30 and the pivot point changes gradually, and first locking structure 30 also can take place to slide in second rectangular groove 22 when taking place to slide in first displacement channel section 122.

In the above technical solution, during the rotation of the television (i.e. during the switching of the horizontal and vertical screens of the television), the steering bracket 20 rotates relative to the supporting frame 10, the first locking structure 30 can slide along the track of the first distance groove section 121 in the first distance groove section 121, when the first locking structure 30 slides from the first distance groove section 121 to the first distance-changing groove section 122, because the distance between the pivot point between the supporting body 11 and the bracket body 21 and the first distance-changing groove section 122 changes gradually, that is, when the first locking structure 30 slides in the first distance-changing groove section 122, the distance between the axis of the first locking structure 30 and the pivot point changes gradually, the first locking structure 30 slides in the second long groove 22 while sliding in the first distance-changing groove section 122, so that the first locking structure 30 moves relative to the bracket body 21, therefore, friction force is generated between the first locking structure 30 and the support body 21, and when the television rotates, the friction force generated between the first locking structure 30 and the support body 21 can effectively provide rotation resistance for the television which rotates to a larger angle, so that the problem that the television is damaged due to the fact that the television rotates to the larger angle and generates larger speed is avoided.

Preferably, in the first embodiment of the present invention, the central angle corresponding to the first distance groove segment 121 may be any angle between 20 ° and 80 °.

Of course, in an alternative embodiment not shown in the drawings, it is also possible to provide the first elongated slot 12 on the bracket body 21 and the second elongated slot 22 on the support body 11. In this way, during the rotation of the bracket body 21 relative to the support body 11, the support body 11 abuts against the first locking structure 30, and the first locking structure 30 moves relative to the support body 11 and generates a frictional force to provide a rotational resistance.

Specifically, in the first embodiment of the present invention, the first locking structure 30 includes a first locking member and a first detachment prevention member 33, the first locking member passes through the first elongated groove 12 and the second elongated groove 22 and then is connected to the first detachment prevention member 33, and the first locking member or the first detachment prevention member 33 abuts against the bracket body 21. Thus, the first locking member slides in the first variable pitch slot section 122 and also slides in the second elongated slot 22, so that both the first locking member and the first anti-release member 33 move relative to the bracket body 21, and friction is generated between the first locking member or the first anti-release member 33 and the bracket body 21, thereby avoiding the problem of damage to the television due to the fact that the television rotates to a larger angle and generates a larger speed.

Of course, in an alternative embodiment not shown in the drawings, the first locking structure 30 may include only a first locking member, which is inserted into the first elongated groove 12 and the second elongated groove 22, and which abuts against the bracket body 21. Preferably, the first locking member is a rivet, and one end of the rivet is riveted through the second elongated slot 22 and the first elongated slot 12, so that the rivet can abut against the bracket body 21, thereby generating a frictional force when the rivet moves relative to the bracket body 21.

It should be noted that in the first embodiment of the present invention, the first locking member is inserted into the first elongated groove 12 and the second elongated groove 22, but the first locking member is inserted through the first elongated groove 12 and the second elongated groove 22 in no order, that is, the first locking member may be inserted through the first elongated groove 12, then inserted through the second elongated groove 22, and then connected to the first anti-release member 33, so that the first anti-release member 33 is abutted against the bracket body 21; alternatively, the first locking member may be passed through the second elongated slot 22, then through the first elongated slot 12, and then connected to the first anti-slip member 33 such that a portion of the first locking member (i.e., the end cap of the first locking member) abuts the bracket body 21.

Specifically, in the first embodiment of the present invention, by providing the auxiliary rotating structure, the pivotal connection between the bracket body 21 and the support body 11 can be realized, so that the bracket body 21 has at least a longitudinal position and a lateral position with respect to the support body 11.

It should be noted that, as shown in fig. 4, in the first embodiment of the present invention, the first distance groove segment 121 includes an arc groove segment, and a center of the arc groove segment is overlapped with the first through hole 13.

With the above arrangement, when the first locking member slides along the track of the first distance groove section 121 in the first distance groove section 121, the first locking member slides relative to the support body 11, and the first locking member does not slide relative to the holder body 21, and one of part of the first locking member (the end cap of the first locking member) and the first separation preventing member 33 abuts against the support body 11, so that a friction force is generated at one side of the support body 11 during the movement; when the first locking member slides along the track of the first variable pitch slot section 122 in the first variable pitch slot section 122, the first locking member will slide relative to the support body 11 and the support body 21, and one of the part of the first locking member (the end cap of the first locking member) and the first anti-release member 33 will abut against the support body 11, and the other of the part of the first locking member (the end cap of the first locking member) and the first anti-release member 33 will abut against the support body 21, so that during the movement, friction will be generated on the support body 21, and friction will also be generated on the support body 11, so that the resistance provided by the first locking structure 30 during the rotation of the television will be increased gradually, which just can counteract the acceleration effect caused by the shift of the center of gravity of the television, and finally, the eccentric television can descend slowly and uniformly during the rotation, thereby ensuring the safety of the product in the using process.

As shown in fig. 4, in the first embodiment of the present invention, the first pitch groove segment 122 includes a straight groove segment.

Through the arrangement, when the first locking piece slides in the linear groove section, the distance between the axis of the first locking piece and the pivot point can be gradually changed, so that the first locking piece can slide in the first variable-distance groove section 122 and can also slide in the second long-strip groove 22, and thus the first locking piece can drive the first anti-falling piece 33 to move relative to the bracket body 21, so that friction force is generated between the first anti-falling piece 33 and the bracket body 21 or between the first locking piece and the bracket body 21, and thus when the television rotates, the friction force generated between the first locking structure 30 and the bracket body 21 can effectively provide rotation resistance for the television rotating to a larger angle, and the problem that the television is damaged due to the fact that the television rotates to a larger angle and generates a larger speed is avoided.

As shown in fig. 4 and 5, in the first embodiment of the present invention, the second elongated groove 22 extends in the radial direction of the first pitch groove segment 121. In this way, the first locking member can be made to slide more smoothly within the first pitch change groove section 122.

As shown in fig. 4, in the first embodiment of the present invention, the first locking structure 30 has at least a first preset position engaged with the end of the first distance-measuring groove section 121 and a second preset position engaged with the end of the first distance-varying groove section 122 in the first elongated groove 12, and when the first locking structure 30 is in the first preset position, a first connection line is formed between the axis of the first locking structure 30 and the pivot point; when first locking structure 30 was located the second and predetermines the position, first locking structure 30's axis and pivot point between have the second line, have contained angle A between first line and the second line, contained angle A satisfies: a is 90 ° ± 10 °, when the first locking structure 30 is at the first preset position, the stent body 21 is at the longitudinal position; when the first locking structure 30 is in the second preset position, the bracket body 21 is in the transverse position.

Through the arrangement, the maximum rotation angle of the television can be limited to 80-100 degrees, so that the transverse and vertical screen switching of the television can be realized.

It should be noted that, in the first embodiment of the present invention, the end of the first pitch groove segment 121 refers to an end of the first pitch groove segment 121 away from the first pitch groove segment 122, and the end of the first pitch groove segment 122 refers to an end of the first pitch groove segment 122 away from the first pitch groove segment 121.

As shown in fig. 1, 3, 4 and 5, in the first embodiment of the present invention, the auxiliary rotating structure includes a third elongated slot 14 provided on the support body 11, the third elongated slot 14 extends around the pivot point, the third elongated slot 14 includes a third distance slot segment 141 and a third distance slot segment 142 connected to the third distance slot segment 141; the auxiliary rotating structure further comprises a fourth long groove 24 arranged on the bracket body 21, and the extending direction of the third distance groove section 141 and the extending direction of the third distance changing groove section 142 form included angles with the extending direction of the fourth long groove 24 respectively; the auxiliary rotating structure further includes a second locking structure 50, the second locking structure 50 is disposed through the third elongated slot 14 and the fourth elongated slot 24, the second locking structure 50 abuts against the bracket body 21, and the second locking structure 50 is in sliding fit with the fourth elongated slot 24, the second locking structure 50 is in sliding fit with the third elongated slot 14, when the second locking structure 50 slides in the third distance slot section 141, a distance between an axis of the second locking structure 50 and the pivot point is unchanged, when the second locking structure 50 slides in the third distance-variable slot section 142, a distance between the axis of the second locking structure 50 and the pivot point is gradually changed, and when the second locking structure 50 slides in the third distance-variable slot section 142, the second locking structure 50 also slides in the fourth elongated slot 24.

Through the arrangement, in the process of switching the transverse and vertical screens of the television, the steering bracket 20 can rotate relative to the support frame 10, when the second locking structure 50 slides in the third variable pitch groove section 142, the second locking structure 50 can slide in the fourth long groove 24, and thus the second locking structure 50 can move relative to the bracket body 21, so that friction force is generated between the second locking structure 50 and the bracket body 21, and thus, the rotation resistance to the bracket body 21 can be further increased, and the problem that the television is damaged due to the fact that the television rotates to a larger angle and generates a larger speed is better avoided.

Of course, in an alternative embodiment not shown in the drawings, it is also possible to provide the third elongated slot 14 on the bracket body 21 and the fourth elongated slot 24 on the support body 11. In this way, during the rotation of the bracket body 21 relative to the support body 11, the support body 11 abuts against the second locking structure 50, and the second locking structure 50 moves relative to the support body 11 and generates a frictional force to provide a rotational resistance.

Specifically, in the first embodiment of the present invention, the second locking structure 50 includes a second locking member and a second anti-release member 51, the second locking member passes through the third elongated slot 14 and the fourth elongated slot 24 and then is connected to the first anti-release member 33, and the second locking member or the second anti-release member 51 abuts against the bracket body 21. Thus, the second locking member slides in the third displacement groove section 142 and also slides in the fourth elongated groove 24, so that the second locking member and the second anti-release member 51 move relative to the bracket body 21, and friction force is generated between the second locking member or the second anti-release member 51 and the bracket body 21, thereby avoiding the problem that the television is damaged due to the fact that the television rotates to a larger angle and generates a larger speed.

Of course, in an alternative embodiment not shown in the drawings, the second locking structure 50 may comprise only a second locking member, which is inserted into the third elongated slot 14 and the fourth elongated slot 24 and abuts against the bracket body 21. Preferably, the second locking member is a rivet, and one end of the rivet is riveted through the fourth elongated slot 24 and the third elongated slot 14, so that the rivet can abut against the bracket body 21, thereby generating a frictional force when the rivet moves relative to the bracket body 21.

It should be noted that in the first embodiment of the present invention, the central angle of the third distance slot segment 141 may be any angle between 20 ° and 80 °, and the central angle of the third distance slot segment 141 may be the same as or different from the central angle of the first distance slot segment 121.

As shown in fig. 4, in the first embodiment of the present invention, the third pitch groove segment 142 includes a straight groove segment.

Through the arrangement, when the second locking part slides in the linear groove section, the distance between the axis of the second locking part and the pivot point can be gradually changed, so that the second locking part can slide in the third variable-pitch groove section 142 and can also slide in the fourth long groove 24, and thus the second locking part can drive the second anti-falling part 51 to move relative to the bracket body 21, so that friction force is generated between the second anti-falling part 51 and the bracket body 21 or between the second locking part and the bracket body 21, and thus when the television rotates, the friction force generated between the first locking structure 30 and the bracket body 21 can effectively provide rotation resistance for the television rotating to a larger angle, and the problem that the television is damaged due to the fact that the television rotates to a larger angle and generates a larger speed is avoided.

As shown in fig. 4 and 5, in the first embodiment of the present invention, the fourth elongated groove 24 extends in the radial direction of the third pitch groove segment 142. In this way, the second locker can be more smoothly slid in the third variable pitch groove section 142.

As shown in fig. 4, in the first embodiment of the present invention, the third elongated slot 14 and the first elongated slot 12 are respectively located on both sides of the pivot point, and the third pitch slot segment 142 is located on the front side of the third distance slot segment 141 and the first pitch slot segment 122 is located on the front side of the first distance slot segment 121 in the rotational direction of the bracket body 21 with respect to the support body 11.

Through the arrangement, in the rotating process of the bracket body 21 relative to the supporting body 11, the first locking piece can slide in the first distance groove section 121 firstly and then slide in the first distance-variable groove section 122, and similarly, the second locking piece can slide in the third distance groove section 141 firstly and then slide in the third distance-variable groove section 142 secondly, so that when the bracket body 21 rotates to a large angle relative to the supporting body 11, friction force can be generated on the surface of the bracket body 21, and the bracket body 21 can effectively provide rotating resistance for a television which rotates to the large angle.

As shown in fig. 4 and 5, in the first embodiment of the present invention, the length of the first pitch groove segment 122 is smaller than the length of the third pitch groove segment 142, and the length of the second elongated groove 22 is smaller than the length of the fourth elongated groove 24.

With the above arrangement, the television horizontal and vertical screen switching process is as shown in fig. 3 and fig. 6 to 10, and as the rotation angle of the television increases, the center of gravity of the television shifts more and more, and the acceleration effect on the rotation movement becomes greater and greater. When the first locking member and the second locking member are both static relative to the bracket body 21, namely the first locking member slides in the first distance groove section 121, and the second locking member slides in the third distance groove section 141, at this time, the bracket body 21 does not generate resistance to the rotation movement; when the bracket body 21 continues to rotate until the second locking member slides to the third variable pitch slot section 142, at this time, the first locking member still slides in the first constant pitch slot section 121, and the first locking member still stands still relative to the bracket body 21 and does not provide resistance, while the second locking member starts to move in the fourth long slot 24 on the bracket body 21, and the friction between the second locking member or the second anti-release member 51 and the bracket body 21 starts to generate resistance to the rotational movement; as the rotation of the bracket body 21 continues until the first locking member slides into the first variable pitch slot section 122, the second locking member continues to move in the fourth elongated slot 24 in the bracket body 21, and at this point the first locking member begins to move in the second elongated slot 22 in the bracket body 21, and the friction between the first locking member or first anti-release member 33 and the bracket body 21 begins to provide resistance to the rotational movement. Thus, as the rotation movement is performed and the rotation angle is increased, the friction force on the bracket body 21 can sequentially provide resistance to the rotation movement in a stepwise manner, so that the television can rotate more stably in the process of switching the horizontal screen and the vertical screen.

Preferably, in the first embodiment of the present invention, the central angle of the first distance groove segment 121 is 70 °, and the central angle of the third distance groove segment 141 is 45 °.
