Description

Technical Field

[0001] This invention relates to a television set, its bracket, and a position control method. Background Technology

[0002] Televisions play an irreplaceable role in daily life and are a long-standing form of entertainment. Some existing televisions are mounted or placed on television stands that can be raised, lowered, and rotated, allowing viewers to adjust the height and angle of the television and adopt different postures, such as sitting or lying down, thus improving viewing comfort. For example, patent CN214008675U discloses a television stand that includes a base, a rotating bracket rotatably mounted on the base, and a lifting bracket slidably mounted on the rotating bracket. The television stand also includes a detection switch, detection contacts, a lifting motor, and a controller, which together control the angle at which the television can be raised and lowered. However, this type of television stand has the following problems: during the rotation of the television, there is a problem of power cables getting tangled. Even if the television rotates in different directions, the cable tangling problem cannot be completely avoided, and rotating in the same direction is more likely to cause the cable to get tangled one or more times, which is unsightly and poses a safety hazard. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a television set, a television set bracket, and a method for controlling the position of the television set, thereby avoiding cable tangling and improving safety during use.

[0004] A first aspect of the invention relates to a television stand, comprising a first base and a second base, the first base and the second base being rotatably connected relative to each other; the stand further comprises:

[0005] A stop block, which is movably disposed on the first base;

[0006] A pusher block is disposed on the second base;

[0007] The stop block has a first limit position and a second limit position. When the second base rotates to the left relative to the first base, the push block can push the stop block to the first limit position. When the push block is blocked, the second base rotates 180 degrees to the left from the initial position and then stops. When the second base rotates to the right relative to the first base, the push block can push the stop block to the second limit position. When the push block is blocked, the second base rotates 180 degrees to the right from the initial position and then stops.

[0008] In a preferred embodiment, the stop block is slidably disposed on the first base along a straight or arc path.

[0009] In a more preferred embodiment, the first base includes a base plate and a connecting seat disposed on the base plate. The connecting seat has a first side surface, which is a vertical plane. The stop block is slidably disposed on the first side surface along a straight line.

[0010] Furthermore, one or more connecting pins are provided on the first side, and the stop is provided with an oblong hole for inserting the connecting pin. The oblong hole extends in the left-right direction, and the connecting pin is inserted into the oblong hole and allowed to slide left and right within the oblong hole.

[0011] In a more preferred embodiment, the second base is located above the first base, the push block extends downward from the lower surface of the second base, the push block has a contact surface, the contact surface being part of a sphere or a cylindrical surface, the contact surface being able to abut against the stop block and slide relative to the stop block.

[0012] In a more preferred embodiment, the upper end of the push block is fixed to the second base or is rotatably inserted into the second base about its own axis, and the lower end of the push block has a cylindrical portion, the side of which can abut against the stop block and slide relative to the stop block.

[0013] In a preferred embodiment, the bracket includes a plurality of angle indication mechanisms for indicating the angle of rotation of the second base relative to the first base, the angle indication mechanisms being disposed on the first base and / or the second base.

[0014] In a more preferred embodiment, the second base is rotatably connected to the first base via a pivot extending in a vertical direction; the first base includes a base plate and a connecting seat disposed on the base plate, the connecting seat having an upper surface facing upwards towards the second base, and a plurality of mounting slots being formed on the upper surface of the connecting seat, the plurality of mounting slots and the stop block being spaced apart along the same circumferential direction of the pivot; the angle indicating mechanism includes a plurality of balls and a plurality of elastic elements, the balls being disposed in the mounting slots, and the elastic elements being disposed between the balls and the mounting slots; the balls have a retracted position where they are pressed into the mounting slots by the push block and an extended position where they are disengaged from the push block and extend upwards out of the mounting slots.

[0015] In a preferred embodiment, the bracket further includes an initial position indication mechanism for indicating whether the second base is in its initial position. The initial position indication mechanism includes a positioning groove on the first base, a ball movable in the positioning groove in a vertical direction, and a positioning post on the second base. When the second base is in the initial position, the positioning post presses on the ball, and the ball is retracted in the positioning groove. When the second base leaves the initial position, the positioning post disengages from the ball, and the ball extends upward out of the positioning groove.

[0016] In a more preferred embodiment, the lower surface of the positioning post has a groove into which the ball can be ejected.

[0017] In a preferred embodiment, the bracket further includes a cooperating detection switch and a trigger, one of which is disposed on the first base and the other on the second base. When the second base is in the initial position, the trigger and the detection switch are in contact or opposite to each other, and the detection switch is triggered to emit a detection signal.

[0018] In a preferred embodiment, the bracket further includes a controller and a lifting mechanism for driving the TV mounting bracket to rise and fall, wherein the input terminal of the controller is electrically connected to the detection switch, and the output terminal of the controller is electrically connected to the lifting mechanism.

[0019] In a preferred embodiment, the detection switch includes a micro switch, the micro-hole switch is disposed on a vertical side of the first base, and the trigger includes a protrusion extending downward from the lower surface of the first base.

[0020] A second aspect of the invention relates to a television set including the aforementioned stand, wherein the main unit of the television set is disposed on the stand.

[0021] A third aspect of the present invention relates to a position control method for a television set, employing the aforementioned bracket, the position control method comprising the following steps:

[0022] Rotate the second base to the left until the push block touches the stop block and pushes the stop block to its first limit position. At this point, the second base rotates 180 degrees to the left relative to its initial position and cannot continue to rotate to the left.

[0023] Rotate the second base to the right until the push block touches the stop block and pushes the stop block to its second limit position. At this point, the second base rotates 180 degrees to the right relative to its initial position and cannot continue to rotate to the right.

[0024] The lifting mechanism of the support is permitted to operate only after the second base has returned to its initial position.

[0025] The present invention adopts the above solution, which has the following advantages compared with the prior art:

[0026] The TV stand of the present invention can rotate to the left or right at an angle not exceeding 180 degrees, which can effectively prevent cables from getting tangled on the stand one or more times, and can also effectively prevent cables from twisting and knotting. At the same time, while ensuring that the TV stand can rotate to the left or right at an angle not exceeding 180 degrees, the TV can rotate to the left and right at least 360 degrees, so that the TV can be adjusted to any direction.

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more readily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof.

[0047] In this document, the terms “upper,” “lower,” “front,” “rear,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings with the second base in the initial position. They are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] Figures 1 to 11 A television stand is shown, which is used to mount the main unit of the television and allows the main unit to rotate and be raised / lowered. (See reference) Figures 1 to 11 As shown, the bracket includes a first base 1 and a second base 2, which are rotatably connected relative to each other. In this embodiment, the second base 2 is disposed above the first base 1; in some other embodiments, the first base 1 may be disposed above the second base 2.

[0049] In this embodiment, the second base 2 is rotatably connected to the first base 1 via a rotating shaft that extends vertically. That is, the second base 2 can rotate relative to the first base 1 in a horizontal plane. The first base 1 includes a base plate 11 and a connecting seat 12, with the connecting seat 12 fixed to the base plate 11. The rotating shaft is disposed within the connecting seat 12, and a bearing is provided between the second base 2 and the rotating shaft.

[0050] The bracket also includes a stop block 3 and a push block 4 that cooperate with each other. The stop block 3 is movably mounted on the first base 1, and the push block 4 is mounted on the second base 2. The stop block 3 has a first extreme position (e.g., ...). Figure 4 (as shown) and second extreme positions (as shown) Figure 5 (As shown). When the second base 2 rotates to the left relative to the first base 1, the push block 4 can push the stop block 3 to the first extreme position. When the push block 4 is blocked, the second base 2 stops rotating 180 degrees to the left from its initial position. When the second base 2 rotates to the right relative to the first base 1, the push block 4 can push the stop block 3 to the second extreme position. When the push block 4 is blocked, the second base 2 stops rotating 180 degrees to the right from its initial position. With this setting, especially since the stop block 3 can slide within a set stroke, it can be ensured that the second base 2 can only rotate 180 degrees to the left or right, while the sum of the leftward and rightward rotation angles covers a range of 360 degrees. In other words, when the stop block 3 is in the first extreme position, one side of the push block 4 abuts against the stop block 3 to prevent the second base 3 from continuing to rotate; when the stop block 3 is in the second extreme position, the other side of the push block 4 abuts against the stop block 3 to prevent the second base 2 from continuing to rotate; during the switching between the first extreme position and the second extreme position, the push block 4 can contact the stop block 3 and push the stop block 3 to move until the predetermined position is reached.

[0051] The stop block 3 is slidably mounted on the first base 1 along a straight or arc-shaped path. In this embodiment, the stop block 3 is slidably mounted on the first base 1 along a straight path. Specifically, the connecting seat 12 has a first side surface 121, which is a vertical plane located between the upper and lower surfaces of the connecting seat 12. The stop block 3 is slidably mounted on the first side surface 121 along a straight line. One or more connecting pins 1211 are provided on the first side surface 121, and the connecting pins 1211 extend horizontally outward. Figure 9 As shown, the stop block 3 has an oblong hole 31 for inserting the connecting pin 1211, and the oblong hole 31 extends in the left-right direction; the connecting pin 1211 is inserted into the oblong hole 31, and the connecting pin 1211 is allowed to slide left and right within the oblong hole 31, so that the stop block 3 can slide left and right on the connecting seat 12 for a certain distance, that is, the distance between the first limit position and the second limit position mentioned above. Figure 9As shown, the top of the stop block 3 is exposed relative to the upper surface of the connecting seat 12, and the push block 4 specifically abuts against the top of the stop block 3.

[0052] Accordingly, the push block 4 extends downward from the lower surface of the second base 2. The push block 4 has a contact surface 411, which is configured to abut against the stop block 3 and slide relative to the stop block 3 after abutting against it. This prevents the push block 4 from disengaging from the stop block 3 as it continues to rotate in the same direction. When the stop block 3 reaches its first or second extreme position, the push block 4 remains against the stop block 3, preventing it from continuing to rotate in the same direction and forcing it to rotate in the opposite direction, returning to its initial position with the second base 2. In this embodiment, the contact surface 411 is a cylindrical surface, capable of abutting against and sliding relative to the stop block 3. In another embodiment, the contact surface 411 may be part of a sphere.

[0053] like Figure 11 As shown, the upper end of the push block 4 is connected to the second base 2. In this embodiment, the upper end of the push block 4 is inserted into the second base 2 and can be fixed relative to the second base 2 or rotated around its own axis (extending in the vertical direction). The lower end of the push block 4 has a cylindrical portion 41, the side of which is the contact surface 411 mentioned above. The side of the cylindrical portion 41 can abut against the stop block 3 and slide relative to the stop block 3.

[0054] It should also be noted that the shape and arrangement of the connector 12 in this embodiment have been specially designed. Combined with... Figure 7 and Figure 8 As shown, from a top-down view, the connecting seat 12 is an axisymmetric shape with two arched portions cut off, specifically having symmetrical left and right portions. Specifically, the connecting seat 12 has two planar sides, namely a first side 121 (rear side) and a second side 121 (front side), both sides being parallel and vertical planes. The connecting seat 12 also has two arc-shaped sides connecting the first side 121 and the second side, the orthographic projection of which onto the horizontal plane is an arc shape. The upper surface of the connecting seat 12 faces the upper second base 2 and is preferably parallel to the lower surface of the second base 2; the lower surface of the connecting seat 12 is in contact with the base plate 11.

[0055] Multiple mounting slots 123 are provided on the upper surface of the connecting seat 12, and the mounting slots 123 are spaced apart along the same circumferential direction of the rotating shaft (connecting seat 12). Specifically, N mounting slots 123 are provided on the left and right sides of the connecting seat 12. The N mounting slots 123 on the left side are equally spaced along the circumferential direction, and the N mounting slots 123 on the right side are equally spaced along the circumferential direction. In the attached drawing, three mounting slots 123 are provided on the left and right sides respectively, and the central angle between adjacent mounting slots 123 is 45 degrees. Furthermore, the aforementioned stop block 3 and the multiple mounting slots 123 are located on the same circumference, which is consistent with the rotation path of the push block 4. That is, during the push block 4's 180-degree rotation to the left, it will pass through the three mounting slots 123 on the left side and the stop block 3 in sequence; during the push block 4's 180-degree rotation to the right, it will pass through the three mounting slots 123 on the right side and the stop block 3 in sequence.

[0056] Furthermore, the bracket includes multiple angle indication mechanisms for indicating the angle of rotation of the second base 2 relative to the first base 1. These angle indication mechanisms are disposed on the first base 1 and / or the second base 2. In this embodiment, the angle indication mechanism includes multiple balls 124 and multiple elastic elements. The balls 124 are disposed in the mounting groove 123, and the elastic elements are disposed between the balls 124 and the mounting groove 123. The balls 124 have a retracted position where they are pressed into the mounting groove 123 by the push block 4 and an extended position where they protrude upwards from the mounting groove 123 after being released from the push block 4. A "click" sound is emitted when the push block 4 presses down on and disengages from the balls 124, indicating to the user that the second base 2 has rotated through the corresponding angle.

[0057] The bracket also includes an initial position indication mechanism 5 for indicating whether the second base 2 is in its initial position. Figure 6 As shown, the initial position indication mechanism 5 includes a positioning groove 51 on the first base 1, a ball 52 movable in the positioning groove 51, and a positioning post 53 on the second base 2. When the second base 2 is in the initial position, the positioning post 53 presses on the ball 52, and the ball 52 is retracted in the positioning groove 51; when the second base 2 leaves the initial position, the positioning post 53 disengages from the ball 52, and the ball 52 extends upward out of the positioning groove 51. Correspondingly, a "click" sound is emitted when the positioning post 53 presses on and disengages from the ball 52, indicating to the user that the second base 2 has turned to the initial position. Furthermore, the lower surface of the positioning post 53 has a groove into which the ball 52 can be ejected. In this embodiment, the positioning groove 51 is specifically disposed on the base plate 11 of the first base 1, located outside the connecting seat 12, improving space utilization.

[0058] The bracket also includes a detection switch 6 and a trigger 21 that cooperate with each other. One of the detection switch 6 and the trigger 21 is disposed on the first base 1 and the other is disposed on the second base 2. When the second base 2 is in the initial position, the trigger 21 and the detection switch 6 are in contact or opposite each other, and the detection switch 6 is triggered to send a detection signal. The bracket further includes a controller and a lifting mechanism for driving the TV mounting bracket to rise and fall. The input terminal of the controller is electrically connected to the detection switch 6, and the output terminal of the controller is electrically connected to the lifting mechanism. When the trigger 21 and the detection switch 6 are in contact or opposite each other, the detection switch 6 is triggered to send a detection signal to the controller. When the controller receives the detection signal, it determines that the second base 2 has returned to its initial position and sends a lifting control signal to the power source (motor or cylinder) of the lifting mechanism. In response to this signal, the lifting mechanism drives the TV set to adjust its height accordingly.

[0059] In this embodiment, as Figure 10 As shown, the detection switch 6 includes a microswitch, and the micro-orifice switch is disposed on the second side of the first base 1. The microswitch has a roller 61, and the trigger 21 includes a protrusion extending downward from the lower surface of the first base 1. When the protrusion presses on the roller 61, the roller 61 moves downward to press the switch contact, thereby triggering and emitting the aforementioned detection signal. In the radial direction, the distance between the trigger 21 and the center is greater than the distance between the stop 3 and the center, thereby the trigger 21 avoids the ball 124 and the stop 3.

[0060] This embodiment also provides a method for controlling the position of a television set, which can adjust the angle and height of the television set's main unit. The aforementioned bracket can be used.

[0061] The position control method includes the following steps:

[0062] Rotate the second base 2 to the left until the push block 4 abuts against the stop block 3 and pushes the stop block 3 to its first limit position. At this time, the second base 2 rotates 180 degrees to the left relative to its initial position and cannot continue to rotate to the left.

[0063] Rotate the second base 2 to the right until the push block 4 abuts against the stop block 3 and pushes the stop block 3 to its second limit position. At this time, the second base 2 rotates 180 degrees to the right relative to its initial position and cannot continue to rotate to the right.

[0064] The lifting mechanism of the bracket is allowed to operate only after the second base 2 returns to its initial position.

[0065] The support and position control method have the following advantages:

[0066] 1. The TV stand should not be rotated more than 180 degrees to the left or right. This can effectively prevent cables from getting tangled on the stand, and also prevent cables from twisting or knotting.

[0067] 2. Provided that the angle of rotation of the TV stand to the left or right does not exceed 180 degrees, the range of rotation of the TV to the left and right shall cover at least 360 degrees, so that the TV can be adjusted to any direction.

[0068] 3. The second base 2 can provide prompts during its rotation and whether it returns to its initial position, so that users can accurately know the angle and status of the second base 2, which makes it highly safe to use.

[0069] 4. The special design of the connector 12 can save space in the front and back directions, which helps to reduce the overall size of the bracket, especially the front and back dimensions of the bracket. This is beneficial for the installation of the TV and makes it more convenient for users.

[0070] 5. The TV stand should only be raised or lowered after ensuring that the second base 2 has returned to its initial state. This is to prevent the TV host from hitting obstacles when it is raised or lowered at an unexpected angle. On the other hand, with the second base 2 in its initial state, the cable is also in its initial state. It is not stretched or bent due to the rotation of the host. The cable will not be overstretched due to the raising or lowering of the stand, and the cable twisting can be avoided as much as possible, which improves the safety of use.
