Detailed Description

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

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

It should be noted that, in the embodiment of the present application, the stand body 21 is switched from the vertical position to the horizontal position, that is, the television is switched from the horizontal screen to the vertical screen.

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

It should be noted that the supporting device of the embodiment of the present application is applicable to not only eccentric televisions, but also televisions with centered centers of gravity.

The inventor knows a supporting device which realizes the slow descending effect in the rotating process of the eccentric television by increasing the number of friction gaskets and increasing the locking torsion of the friction gaskets. However, this approach requires a large frictional resistance to the rotational movement, which results in a television set that is subject to a large resistance immediately upon initial rotation, thereby reducing the customer experience.

Accordingly, as shown in fig. 1, 3, 4 and 5, a first embodiment of the present invention provides a supporting device. The support means comprises a support frame 10, a steering bracket 20, an auxiliary rotating structure and a first locking structure 30. The support frame 10 is connected with a foundation to be installed, the support frame 10 comprises a support body 11 and a first long strip groove 12 arranged on the support body 11, and the first long strip groove 12 comprises a first distance groove section 121 and a first distance changing groove section 122 connected with the first distance groove section 121; the steering bracket 20 comprises a bracket body 21 and a second long strip groove 22 arranged on the bracket body 21, wherein the extending direction of the first spacing groove section 121 and the extending direction of the first spacing groove section 122 are respectively arranged at an included angle with the extending direction of the second long strip groove 22; the auxiliary rotating structure is arranged on the support body 11 and the support body 21 and is used for enabling the support body 21 to be in pivot connection 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 lateral position; the first locking structure 30 is arranged in the first long groove 12 and the second long groove 22 in a penetrating mode, the first locking structure 30 is abutted to the support body 21, the first locking structure 30 is in sliding fit with the second long groove 22, the first locking structure 30 is in sliding fit with the first long groove 12, when the first locking structure 30 slides in the first distance groove section 121, the distance between the axis of the first locking structure 30 and the pivot point is unchanged, when the first locking structure 30 slides in the first distance groove section 122, the distance between the axis of the first locking structure 30 and the pivot point is gradually changed, and the first locking structure 30 slides in the second long groove 22 while sliding in the first distance groove 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 support frame 10, the first locking structure 30 may slide along the track of the first fixed distance slot segment 121 in the first fixed distance slot segment 121, and when the first locking structure 30 slides from the first fixed distance slot segment 121 to the first fixed distance slot segment 122, the distance between the pivot point between the support body 11 and the bracket body 21 and the first fixed distance slot segment 122 will change, i.e. when the first locking structure 30 slides in the first fixed distance slot segment 122, the distance between the axis of the first locking structure 30 and the pivot point will gradually change, so that the first locking structure 30 slides in the second elongated slot 22 while sliding in the first fixed distance slot segment 122, and thus the first locking structure 30 will move relative to the bracket body 21, so that a friction force is generated between the first locking structure 30 and the bracket body 21, and thus, when the television rotates, the above-mentioned friction force generated between the first locking structure 30 and the bracket body 21 will effectively prevent the television from damaging the rotation angle due to a large rotation angle.

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

Of course, in alternative embodiments not shown in the drawings, the first elongated groove 12 may be provided on the bracket body 21 and the second elongated groove 22 may be provided 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 friction force to provide rotation resistance.

Specifically, in the first embodiment of the present invention, the first locking structure 30 includes a first locking member and a first anti-falling member 33, the first locking member passes through the first elongated slot 12 and the second elongated slot 22 and is connected to the first anti-falling member 33, and the first locking member or the first anti-falling member 33 abuts against the bracket body 21. In this way, the first locking member slides in the second elongated slot 22 while sliding in the first variable-pitch slot 122, so that the first locking member and the first anti-falling member 33 both move relative to the bracket body 21, and friction force is generated between the first locking member or the first anti-falling member 33 and the bracket body 21, so as to avoid the problem that the television is damaged due to the rotation of the television to a larger angle and a larger speed.

Of course, in an alternative embodiment not shown in the drawings, the first locking structure 30 may also include only a first locking member, where the first locking member passes through the first elongated slot 12 and the second elongated slot 22, and the first locking member 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, and thus friction is generated when the rivet moves relative to the bracket body 21.

In the first embodiment of the present invention, the first locking member is inserted into the first elongated slot 12 and the second elongated slot 22, however, the first locking member may be inserted into the first elongated slot 12 and the second elongated slot 22 in no sequence, that is, the first locking member may be inserted into the first elongated slot 12, then inserted into the second elongated slot 22, and then connected to the first anti-release member 33, so that the first anti-release member 33 abuts against the bracket body 21; alternatively, the first locking member passes through the second elongated slot 22, then passes through the first elongated slot 12, and then is connected to the first anti-release member 33, so that a portion of the first locking member (i.e., the end cap of the first locking member) abuts against the bracket body 21.

Specifically, in the first embodiment of the present invention, by providing the auxiliary rotating structure, the pivotal connection between the stand body 21 and the support body 11 can be achieved so that the stand body 21 has at least the longitudinal position and the 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 section 121 includes an arc groove section, and the center of the arc groove section is overlapped with the first through hole 13.

With the above arrangement, when the first locking member slides in the first distance groove section 121 along the trajectory of the first distance groove section 121, the first locking member slides with respect to the support body 11, and the first locking member does not slide with respect to the bracket body 21, part of one of the first locking member (the end cap of the first locking member) and the first falling prevention member 33 abuts against the support body 11, so that a friction force is generated at one side of the support body 11 during movement; when the first locking member slides along the track of the first variable-pitch groove section 122 in the first variable-pitch groove section 122, the first locking member slides relative to the support body 11 and also slides relative to the bracket body 21, and one of a part of the first locking member (end cap of the first locking member) and the first anti-drop member 33 is abutted against the support body 11, and the other one of a part of the first locking member (end cap of the first locking member) and the first anti-drop member 33 is abutted against the bracket body 21, so that friction force is generated on the bracket body 21 in the moving process, and friction force is also generated on the support body 11, so that resistance provided by the first locking structure 30 in the rotating process of the television is gradually increased, and can offset acceleration effect caused by the gravity center offset of the television, and slow and uniform descent of the eccentric television in the rotating process is finally realized, so that the safety in the using process of the product is ensured.

As shown in fig. 4, in a first embodiment of the present invention, the first variable pitch slot segment 122 comprises a linear slot segment.

Through the arrangement, when the first locking member slides in the linear groove section, the distance between the axis of the first locking member and the pivot point can be gradually changed, so that the first locking member can slide in the first variable-pitch groove section 122 and also slide in the second long groove 22, and the first locking member can drive the first anti-falling member 33 to move relative to the bracket body 21, so that friction force is generated between the first anti-falling member 33 and the bracket body 21 or between the first locking member and the bracket body 21, and 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, 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.

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 distance groove section 121. In this way, the first locking member can be made to slide more smoothly within the first variable-pitch slot segment 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 matched with the end of the first fixed slot section 121 and a second preset position matched with the end of the first variable slot section 122 in the first elongated slot 12, and when the first locking structure 30 is at the first preset position, a first connection line is formed between the axis of the first locking structure 30 and the pivot point; when the first locking structure 30 is located at the second preset position, a second connecting line is arranged between the axis of the first locking structure 30 and the pivot point, an included angle A is formed between the first connecting line and the second connecting line, and the included angle A meets the following requirements: a=90° ±10°, when the first locking structure 30 is in the first preset position, the bracket body 21 is in the longitudinal position; when the first locking structure 30 is in the second preset position, the bracket body 21 is in the lateral position.

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

In the first embodiment of the present invention, the end of the first distance groove section 121 refers to the end of the first distance groove section 121 away from the first distance groove section 122, and the end of the first distance groove section 122 refers to the end of the first distance groove section 122 away from the first distance groove section 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 extending around the pivot point, the third elongated slot 14 including a third fixed distance slot segment 141 and a third variable distance slot segment 142 connected to the third fixed distance slot segment 141; the auxiliary rotating structure further comprises a fourth long strip groove 24 arranged on the bracket body 21, and the extending direction of the third distance-fixing groove section 141 and the extending direction of the third distance-changing groove section 142 are respectively arranged at an included angle with the extending direction of the fourth long strip groove 24; the auxiliary rotating structure further comprises a second locking structure 50, the second locking structure 50 penetrates through the third long strip groove 14 and the fourth long strip groove 24, the second locking structure 50 is abutted against the bracket body 21, the second locking structure 50 is in sliding fit with the fourth long strip groove 24, the second locking structure 50 is in sliding fit with the third long strip groove 14, when the second locking structure 50 slides in the third fixed-distance groove section 141, the distance between the axis of the second locking structure 50 and the pivot point is unchanged, when the second locking structure 50 slides in the third variable-distance groove section 142, the distance between the axis of the second locking structure 50 and the pivot point is gradually changed, and the second locking structure 50 slides in the fourth long strip groove 24 while sliding in the third variable-distance groove section 142.

Through the arrangement, in the process of switching the transverse screen and the vertical screen of the television, the steering bracket 20 rotates relative to the supporting frame 10, and when the second locking structure 50 slides in the third variable-pitch groove section 142, the second locking structure 50 slides in the fourth long groove 24, so that the second locking structure 50 moves relative to the bracket body 21, and friction force is generated between the second locking structure 50 and the bracket body 21, and in this way, 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 alternative embodiments not shown in the drawings, the third elongated groove 14 may be provided on the bracket body 21 and the fourth elongated groove 24 may be provided 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 friction force to provide rotation resistance.

Specifically, in the first embodiment of the present invention, the second locking structure 50 includes a second locking member and a second anti-falling member 51, where the second locking member passes through the third elongated slot 14 and the fourth elongated slot 24 and is connected to the first anti-falling member 33, and the second locking member or the second anti-falling member 51 abuts against the bracket body 21. In this way, the second locking member slides in the third variable-pitch slot segment 142 and slides in the fourth elongated slot 24, so that the second locking member and the second anti-falling member 51 both move along the bracket body 21, and friction force is generated between the second locking member or the second anti-falling member 51 and the bracket body 21, so that 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.

Of course, in an alternative embodiment not shown in the drawings, the second locking structure 50 may also include only the second locking member, where the second locking member passes through the third elongated slot 14 and the fourth elongated slot 24, and the second locking member 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 friction 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 fixed-distance groove section 141 may be any angle between 20 ° and 80 °, and the central angle of the third fixed-distance groove section 141 may be the same as or different from the central angle of the first fixed-distance groove section 121.

As shown in fig. 4, in a first embodiment of the present invention, the third variable pitch slot segment 142 comprises a linear slot segment.

Through the arrangement, when the second locking member slides in the linear groove section, the distance between the axis of the second locking member and the pivot point can be gradually changed, so that the second locking member can slide in the third variable-pitch groove section 142 and also slide in the fourth long groove 24, and the second locking member can drive the second anti-falling member 51 to move relative to the bracket body 21, so that friction force is generated between the second anti-falling member 51 and the bracket body 21 or between the second locking member and the bracket body 21, and 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, 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.

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 variable-pitch groove segment 142. In this way, the second locking member can be slid within the third gage groove section 142 more smoothly.

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 at two sides of the pivot point, and the third variable-pitch slot segment 142 is located at the front side of the third fixed-pitch slot segment 141 and the first variable-pitch slot segment 122 is located at the front side of the first fixed-pitch slot segment 121 along the rotation direction of the bracket body 21 relative to the support body 11.

Through the above arrangement, in the rotation process of the stand body 21 relative to the support body 11, the first locking member will slide in the first fixed distance slot section 121 first, then slide in the first variable distance slot section 122, and similarly, the second locking member will slide in the third fixed distance slot section 141 first, then slide in the third variable distance slot section 142, so when the stand body 21 rotates to a larger angle relative to the support body 11, a friction force will be generated on the surface of the stand body 21, so that the stand body 21 can effectively provide a rotation resistance for the television rotating to a larger angle.

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

With the arrangement, the switching process of the television horizontal and vertical screens is as shown in fig. 3 and fig. 6 to 10, and as the rotation angle of the television increases, the gravity center of the television shifts more and more, and the acceleration effect on the rotation motion becomes larger and more. When the first locking member and the second locking member are both stationary, i.e. the first locking member slides in the first fixed distance groove section 121 and the second locking member slides in the third fixed distance groove section 141, the support body 21 does not generate resistance to rotational movement; when the bracket body 21 continues to rotate until the second locking member slides to the third variable-pitch groove section 142, at this time, the first locking member still slides in the first fixed-pitch groove section 121 and still stands still relative to the bracket body 21, no resistance is provided, the second locking member starts to move in the fourth elongated groove 24 on the bracket body 21, and friction force between the second locking member or the second anti-drop member 51 and the bracket body 21 starts to generate resistance to the rotational movement; when the bracket body 21 continues to rotate until the first locking member slides to the first variable-pitch groove section 122, the second locking member continues to move in the fourth elongated groove 24 on the bracket body 21, and at this time, the first locking member starts to move in the second elongated groove 22 on the bracket body 21, and the friction force between the first locking member or the first anti-drop member 33 and the bracket body 21 starts to generate resistance to the rotational movement. Thus, with the progress of the rotation motion, the friction force on the bracket body 21 can provide resistance to the rotation motion in a stepwise manner in sequence along with the increase of the rotation angle, 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 fixed distance groove segment 121 is 70 °, and the central angle of the third fixed distance groove segment 141 is 45 °. Such that the length of first gage groove section 122 is less than the length of third gage groove section 142.

As shown in fig. 4, in the first embodiment of the present invention, the first variable-pitch groove section 122 extends in a tangential direction of an end of the first distance groove section 121 near the first variable-pitch groove section 122.

As shown in fig. 4, in the first embodiment of the present invention, the third variable-pitch groove section 142 extends in a tangential direction of an end of the third distance groove section 141 near the third variable-pitch groove section 142.

By the above arrangement, smooth connection between the third fixed-distance groove section 141 and the third variable-distance groove section 142 can be achieved, so that the second locking member can slide from the third fixed-distance groove section 141 to the third variable-distance groove section 142 more smoothly.
