When the driving motor drives the screw rod to rotate, the slider moves back and forth along the axial direction of the screw rod, and when the driving motor drives the slider to slide in a direction close to the upper end of the bracket, the connecting arm drives the bracket to unfold, and when the driving motor drives the slider to slide in a direction away from the upper end of the bracket, the connecting arm drives the bracket to fold.

[0004] The TV stand of the above-mentioned related technology has the following defects during actual use: since the upper end of the connecting arm is hinged to the slider, and the lower end of the connecting arm is hinged to the middle part of the bracket; when the driving motor drives the slider to slide away from the upper end of the bracket to the extreme position so that the TV mounting bracket on the bracket is at the highest point, the angle between the connecting arm and the screw is the smallest, and the load on the connecting arm applies a large axial force to the screw through the slider, which makes the thread on the screw or the slider easily damaged, thereby affecting the service life of the TV stand. Utility Model Content

[0005] The technical problem to be solved by the present application is to overcome the defects of the above-mentioned related technologies and provide a TV bracket with a long service life, which can alleviate or weaken the axial force exerted by the load on the connecting arm on the screw rod when the TV mounting frame is at the highest point.

[0006] The technical solution of this application is to provide a TV stand with the following structure:

[0007] A fixed seat, which is slidably connected to a slider along its length and is connected to a screw nut assembly for driving the slider to slide, and a rotation connection point is provided on the fixed seat;

[0008] A hanging bracket connected to a TV mounting bracket, wherein the upper end of the hanging bracket is rotatably connected to the rotating connection point, and the hanging bracket is provided with a slide rail along the length direction;

[0009] A connecting arm, wherein the upper end of the connecting arm is rotatably connected to the slider, and the lower end of the connecting arm is slidably connected to the slide rail of the hanger.

[0011] In some embodiments, the connecting arm includes two connecting rods, the upper ends of the two connecting rods are respectively rotatably connected to the slider, and the lower ends of the two connecting rods are respectively connected to the two ends of the sliding rod.

[0012] In some embodiments, the fixing seat is provided with a sliding groove along the length direction, the sliding block is connected to a sliding rod, and the sliding rod is slidably connected in the sliding groove; the upper ends of the two connecting rods are respectively connected to the sliding rods.

[0013] In some embodiments, a support plate corresponding to the slide groove is provided on the top of the hanger along the length direction, a pulley is connected to the slide rod, and the outer circumferential wall of the pulley is in contact with the support plate.

[0014] In some embodiments, a positioning protrusion extending into the sliding groove is provided on the inner side wall of the sliding groove at one end away from the rotating connection point, so as to confine the sliding rod in the sliding groove on the side of the positioning protrusion away from the rotating connection point when the sliding rod slides along the length direction of the sliding groove to pass through the positioning protrusion.

Therefore, when the bracket rotates upward to the highest point, the lower end of the connecting arm is far away from the rotation connection point or the upper end of the bracket, so that the tensile force borne by the connecting arm is small, and the axial force of the load on the connecting arm borne by the screw nut assembly becomes smaller; therefore, when the TV mounting frame is at the highest point, the TV bracket can alleviate or weaken the axial force exerted by the load on the connecting arm on the screw, thereby extending the service life of the TV bracket.

Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figures 1 to 4 As shown; The embodiment of the present application discloses a TV stand, which is installed on the ceiling and is used for installing a TV or a monitor. The TV stand includes a fixing base 1, a bracket 2, and a connecting arm 4. The fixing base 1 is installed on the ceiling or the ceiling by fasteners such as screws and connecting bolts. The fixing base 1 is hollow inside, and a slider 601 and a screw nut assembly 6 that drives the slider 601 to slide are slidably connected to the fixing base 1 along the length direction. The screw nut assembly 6 includes a screw 600 and a transmission nut. The screw 600 is arranged along the length direction of the fixing base 1 and is rotatably connected to the fixing base 1. The transmission nut is connected to the slider 601 and is threadedly connected to the screw. The rotation of the screw can drive the slider 601 to reciprocate along the axial direction of the screw.

[0032] In the above embodiment, the transmission nut of the screw-nut assembly 6 can be connected to the slider 601 as an independent component, or it can be integrally formed with the slider 601, that is, a threaded hole passing through the slider 601 is provided in the slider 601, and the threaded hole is threadedly connected to the screw.

[0033] Furthermore, in this embodiment, a television mounting bracket 3 for mounting a television is connected to the hanger 2. A rotation connection point 102 is provided on the fixing base 1. The upper end of the hanger 2 is rotationally connected to the rotation connection point 102, so that the hanger 2 can rotate relative to the fixing base 1 around the axis of the rotation connection point 102 at the upper end of the hanger 2. The upper end of the connecting arm 4 is rotationally connected to the slider 601, and the lower end of the connecting arm 4 is rotationally connected to the hanger 2. When the screw nut assembly 6 drives the slider 601 to move away from the rotation connection point 102 of the fixing base 1, the connecting arm 4 pulls the hanger 2 to rotate and fold upward. When the rod nut assembly drives the slider 601 to move toward the rotation connection point 102 of the fixing base 1, the connecting arm 4 pulls the hanger 2 to rotate and unfold downward.

[0034] It is not difficult to understand that when the screw nut assembly 6 drives the slider 601 to move in the direction away from the rotation connection point 102 of the fixed base 1, the angle between the connecting arm 4 and the fixed base 1 gradually becomes smaller, and when the TV mounting bracket 3 on the bracket 2 rotates upward to the highest point, the angle between the connecting arm 4 and the fixed base 1 is the smallest. At this time, most of the load on the connecting arm 4 is converted into the axial force borne by the screw nut assembly 6, wherein the load on the connecting arm 4 is the weight of the connecting arm 4, the bracket 2, the TV mounting bracket 3 and the TV. The axial force borne by the screw nut assembly 6 can easily damage the threads on the screw nut assembly 6, thereby causing damage to the threads and causing the slider 601 to move unsteadily or even unable to move. For this reason, in this embodiment, see Figure 1 、 Figure 2 and Figure 3 As shown, the bracket 2 is provided with a slide rail along the length direction, and the lower end of the connecting arm 4 is slidably connected to the slide rail of the bracket 2; therefore, when the screw nut assembly 6 drives the slider 601 to move in the direction away from the rotation connection point 102 on the fixed seat 1, the connecting arm 4 drives the bracket 2 to rotate and fold upward, and at the same time, the lower end of the connecting arm 4 slides along the slide rail on the bracket 2 in the direction away from the rotation connection point 102 or the upper end of the bracket 2. Therefore, when the bracket 2 is rotated upward to the highest point, the lower end of the connecting arm 4 is far away from the rotation connection point 102 or the upper end of the bracket 2, so that the tension borne by the connecting arm 4 is small, and the axial force of the load on the connecting arm 4 borne by the screw nut assembly 6 becomes smaller; therefore, when the TV mounting bracket 3 is at the highest point, the TV bracket can alleviate or weaken the axial force exerted by the load on the connecting arm 4 on the screw, avoid damaging the thread on the screw nut assembly 6, and thus prolong the service life of the TV bracket.

[0035] For example, see Figure 5 As shown, when the screw nut assembly 6 drives the slider 601 to move to the middle position of the sliding groove 100, the slider 601 links the connecting arm 4 to rotate the hanger 2 downward and unfold. At this time, the lower end of the connecting arm 4 slides to the middle position of the sliding groove 200; continue to see Figure 6 As shown, the Figure 6 The state shown is the folded state of the bracket 2 or the state where the TV mounting bracket 3 is at the highest point. At this time, the slider 601 slides to the end of the sliding groove 100 away from the rotation connection point 102, and the lower end of the connecting arm 4 slides along the sliding groove 200 to the end of the sliding groove 200 away from the upper end of the bracket 2; that is, from Figure 5 The status shown is Figure 6 In the state shown, the lower end of the connecting arm 4 slides from the middle of the sliding groove 200 to the outer end of the sliding groove 200, and the force on the connecting arm 4 is reduced.

[0036] In the above example, it is easy to understand that when the TV mounting bracket 3 is at its highest point, the farther the lower end of the connecting arm 4 is from the rotation connection point 102 or the upper end of the bracket 2, the longer the moment arm for the bracket 2 to rotate, and the smaller the force on the connecting arm 4. Therefore, when the lower end of the connecting arm 4 slides to the end of the slide rail away from the upper end of the bracket 2, the force on the connecting arm 4 is minimized, and the axial force on the screw nut assembly 6 is also minimized.

[0037] It is not difficult to understand that in this embodiment, the lower end of the connecting arm 4 is slidably connected to the slide rail on the bracket 2, so that there is a certain degree of sliding freedom between the lower end of the connecting arm 4 and the slide rail, that is, when a person touches the bracket 2 or the TV mounting bracket 3 on the bracket 2, the bracket 2 can be rotated upward by a certain angle to prevent a hard collision with the bracket 2 or the TV mounting bracket 3 on the bracket 2, thereby avoiding injuries caused by collision when people move below, thereby making the TV bracket safer to use.

[0038] In the above embodiment, a connecting base 101 is connected to the end of the fixing base 1. The connecting base 101 is provided with a rotation connection point 102. The upper end of the hanger 2 is rotatably connected to the rotation connection point 102 via a rotating shaft 103. The rotation connection point 102 can be an axis hole, an axis, a rotating part, etc.

[0039] In this embodiment, see Figure 1 、 Figure 2 and Figure 4 As shown, the TV stand is an electrically driven TV stand, that is, a drive motor 5 is connected to the fixing base 1, and the drive motor 5 is connected to the screw for driving the screw to rotate. The drive motor 5 drives the screw to rotate, thereby causing the slider 601 to move along the axial direction of the screw. The slider 601 can drive the bracket 2 to rotate an angle through the connecting arm 4, so that the bracket 2 can be folded or unfolded. It can be understood that in this embodiment, the fixing base 1 is also connected to components such as a controller and a power adapter. The power adapter is used to connect to an indoor socket to obtain electricity. The controller is electrically connected to the drive motor 5 to control the operation of the drive motor 5. Of course, in this embodiment, in order to facilitate user operation, the TV stand also includes a remote control, which is used to remotely control the drive motor 5 to operate.

[0040] In this embodiment, see Figure 1 、 Figure 2 and Figure 3 As shown, the hanger 2 is provided with a slide groove 200 along its length, forming a slide rail. A slide rod 401 is slidably connected within the slide groove 200, and the lower end of the connecting arm 4 is connected to the slide rod 401. The slide rod 401 has a clearance fit within the slide groove 200. When the lead screw and nut assembly drives the slide movement, the slide rod 401 slides within the slide groove 200 and rotates about its own axis.

[0041] In other embodiments, the slide rail may also be an independent guide rail installed on the hanger 2 and extending along the length direction of the hanger 2 .

[0042] Furthermore, in this embodiment, the connecting arm 4 includes two connecting rods, the upper ends of the two connecting rods are respectively connected to the slider 601 for rotation, and the lower ends of the two connecting rods are respectively connected to the two ends of the slide bar 401. This arrangement makes the slider 601 have good structural stability when driving the hanger 2 to rotate. For example, see Figure 2 As shown, the two connecting rods are arranged in parallel and respectively on both sides of the hanger 2, and the upper ends of the two connecting rods are respectively rotatably connected to the two sides of the slider 601, and the lower ends of the two connecting rods are respectively connected to the two ends of the slide bar 401 extending out of the slide groove 200.

[0043] In other embodiments, the connecting arm 4 may also include only one connecting rod, the upper end of which is rotatably connected to the slider 601 , and the lower end of which is connected to the slide bar 401 .

[0044] In order to make the lower end of the connecting arm 4 slide more smoothly relative to the slide groove 200 on the hanging rack 2 during the rotation of the hanging rack 2, in this embodiment, see Figure 2 and Figure 3 As shown, a pulley 402 is connected to a slide rod 401. A support plate 201 corresponding to the slide groove 200 is provided at the top of the hanger 2 along its length, and the outer circumferential wall of the pulley 402 is in contact with the support plate 201. In other words, when the slide rod 401 at the lower end of the connecting arm 4 slides along the length of the slide groove 200, the pulley 402 simultaneously slides along the direction of the support plate 201. This ensures that the lower end of the connecting arm 4 slides more smoothly relative to the hanger 2.

[0045] In this embodiment, see Figure 2 and Figure 3 As shown, a sliding groove 100 is provided along the length of the fixed base 1. A sliding rod 400 is connected to the slider 601, and the sliding rod 400 is slidably connected within the sliding groove 100. The upper ends of the two connecting rods are respectively connected to the sliding rod 400. When the screw nut assembly 6 drives the slider 601 to slide along the length of the fixed base 1, the sliding rod 400 on the slider 601 slides synchronously along the length of the sliding groove 100.

[0046] In some embodiments, see Figure 3 and Figure 4 As shown, a positioning protrusion extending into the sliding groove 100 is provided on the inner side wall of the end of the sliding groove 100 away from the rotation connection point 102. When the sliding rod 400 slides along the length direction of the sliding groove 100 and passes the positioning protrusion, the sliding rod 400 is confined in the sliding groove 100 on the side of the positioning protrusion away from the rotation connection point 102. With this arrangement, when the TV stand is packaged at the factory, the hanging bracket 2 is folded. When the hanging bracket 2 drives the connecting arm 4 to slide the sliding rod 400 along the length direction of the sliding groove 100 and passes the positioning protrusion, the sliding rod 400 can be confined to the end of the sliding groove 100 away from the rotation connection point 102. This can prevent the hanging bracket 2 from being accidentally opened, ensuring the safety of packaging and transportation.
