Description

Coupling assembling, connection structure and display screen
Technical Field
The present invention relates to the field of display devices, and in particular, to a connection assembly, a connection structure, and a display screen.
Background
Currently, there is an LED (LIGHT EMITTING Diode) display screen on the market, where each LED display unit board is fixed on a square board capable of being bent, then the LED bulbs are connected by wires, and connected to a power supply and a control system to form a bendable LED display screen, but after the display screen is bent, the width of a gap between two adjacent LED display unit boards is increased, so that a larger black seam appears on the display screen, and the display effect is affected.
Disclosure of Invention
Based on this, it is necessary to provide a connection assembly, a connection structure and a display screen, when the display screen is bent, the display screen can avoid the occurrence of a larger black seam, and the display effect is ensured.
The technical scheme is as follows:
A connection assembly, comprising: the device comprises a first bracket, a second bracket, a first connecting piece, a second connecting piece and a transmission unit, wherein the first bracket is rotationally connected with the second bracket, the first connecting piece is connected with the first bracket, and the second connecting piece is connected with the second bracket; the transmission unit is used for enabling the first connecting piece to be close to the joint of the first bracket and the second bracket when the second bracket and the first bracket rotate relatively; and/or the second connecting piece is matched with the second bracket in a moving way, and when the second bracket and the first bracket rotate relatively, the transmission unit is used for enabling the second connecting piece to be close to the switching position.
When the connecting assembly is applied to the connecting structure of the display screen, the first connecting piece is used for being connected with the first display element, the second connecting piece is used for being connected with the second display element, and after the first display element and the second display element are mounted, the first display element and the second display element form a parallel structure. In the above connection structure, the first display element and the second display element are connected together through the connection assembly, when the second bracket and the first bracket rotate relatively, the second display element will rotate with the second bracket relative to the first display element at this time, so that the first display element and the second display element will form a curved structure, and when the display screen uses the above connection structure, the display screen will also have a curved function correspondingly; and the first display element and the second display element are connected together through the connecting component, when the second bracket rotates relative to the first bracket, the transmission unit can enable the second connecting piece to be close to the switching position of the first bracket and the second bracket, so that the second display element is pulled to move towards the first display element, and a gap between the first display element and the second display element has a reduced trend.
It should be noted that, if the first display element and the second display element are connected by using a conventional rotating connection member such as a rotating shaft or a hinge, when the display screen rotates toward the back of the first display element 300 and the second display element 400, the width of the gap between the first display element and the second display element increases as the width of the second display element rotating relative to the first display element increases. The width of the gap formed between the first display element and the second display element has a tendency of shrinking, which means that the width of the gap between the first display element and the second display element is not actually larger than the width of the gap between the first display element and the second display element after the display screen is bent in a straight state, but means that the first display element and the second display element have a tendency of moving close to each other, so that the width of the gap between the first display element and the second display element has a tendency of shrinking, and the situation that a larger black seam appears on the display screen due to the increase of the width of the gap between the first display element and the second display element can be avoided, and the display effect is ensured.

When the above-mentioned connection assembly 500 is applied to a connection structure of a display screen, the first mounting member 100 is used for mounting the first display element 300, the first display element 300 may be separated from the first mounting member 100 to implement quick maintenance and replacement, the second mounting member 200 is used for mounting the second display element 400, the second display element 400 may be separated from the second mounting member 200 to implement quick maintenance and replacement, and since the first mounting member 100 and the second mounting member 200 are arranged in parallel, after the first display element 300 and the second display element 400 are mounted, the first display element 300 and the second display element 400 may form a parallel structure. It is understood that the first connecting member 510 may be directly connected to the first display element 300, and the second connecting member 520 may be directly connected to the second display element 400, so that the first display element 300 and the second display element 400 form a parallel structure when the first display element 300 and the second display element 400 are assembled. The first display element 300 and the second display element 400 are connected together through the connection assembly 500, when the second bracket 550 and the first bracket 540 rotate relatively, the second display element 400 rotates along with the second bracket 550 relative to the first display element 300, so that the first display element 300 and the second display element 400 form a curved structure, and when the display screen adopts the above connection structure, the display screen also has a curved function correspondingly; and the first display element 300 and the second display element 400 are connected together through the connecting assembly 500, when the second bracket 550 rotates relative to the first bracket 540, the transmission unit can make the second connecting piece 520 approach to the junction between the first bracket 540 and the second bracket 550, so as to pull the second display element 400 to move towards the first display element 300, so that the gap between the first display element 300 and the second display element 400 has a reduced tendency.
It should be noted that, if the first display element 300 and the second display element 400 are connected by using a conventional rotating connection member such as a rotating shaft or a hinge, when the display screen rotates toward the back of the first display element 300 and the second display element 400, as the rotation width of the second display element 400 relative to the first display element 300 increases, the width of the gap 10 formed between the first display element 300 and the second display element 400 increases, and by using the connecting assembly 500 of the present application to connect the first display element 300 and the second display element 400, when the second display element 400 rotates relative to the first display element 300, the second connection member 520 can pull the second display element 400 toward the first display element 300, the width of the gap 10 between the first display element 300 and the second display element 400 does not increase or increases very little within a certain rotation range, and the width of the gap 10 formed between the first display element 300 and the second display element 400 has a tendency to decrease, so that the width of the gap 10 formed between the first display element 300 and the second display element 400 does not indicate that the width of the display screen between the first display element 300 and the second display element 400 indicates that the gap 10 between the first display element 300 and the second display element 400 is larger than the width of the first display element 400, and the gap between the first display element 400 and the second display element 400 can actually decrease because the width of the gap between the first display element 300 and the second display element 400 indicates that the gap between the first display element 300 and the gap and the first display element 400 and the gap between the first display element 300 and the gap between the first display element and the first display element 400 and the gap has a larger trend to be larger.
Of course, in the above-mentioned connection structure, the second connection member 520 may also be movably matched with the second bracket 550, and the transmission unit is used to make the second connection member 520 approach to the junction between the first bracket 540 and the second bracket 550 when the second bracket 550 and the first bracket 540 rotate relatively.
In particular, in this embodiment, in the connection structure, the first connecting member 510 is movably matched with the first bracket 540, the second connecting member 520 is movably matched with the second bracket 550, and when the second bracket 550 and the first bracket 540 rotate relatively, the transmission unit is used to make the first connecting member 510 approach to the junction between the first bracket 540 and the second bracket 550, and the transmission unit is also used to make the second connecting member 520 approach to the junction between the first bracket 540 and the second bracket 550. In this manner, the second mounting member 200 is pulled to move toward the first mounting member 100 by the second connecting member 520, and the first connecting member 510 pulls the first mounting member 100 to move toward the second mounting member 200, so that the first mounting member 100 and the second mounting member 200 are close to each other, and the width of the gap 10 formed between the first display element 300 and the second display element 400 is more remarkably reduced.
It should be noted that, the first display element 300 and the second display element 400 may be LED display modules, and the first mounting member 100 and the second mounting member 200 are both frame-shaped structures.

Specifically, the first bracket 540 is provided with a first assembly hole, the second bracket 550 is provided with a second assembly hole, and the rotating shaft 530 is inserted into the first assembly hole and the second assembly hole. The rotating shaft 530 is used for enabling the first bracket 540 and the second bracket 550 to be rotationally connected, and because the first bracket 540 is movably matched with the first connecting piece 510, the first connecting piece 510 is connected with the first mounting piece 100, the second bracket 550 is movably matched with the second connecting piece 520, the second connecting piece 520 is connected with the second mounting piece 200, and when the first bracket 540 and the second bracket 550 are relatively rotated by means of the rotating shaft 530, the first mounting piece 100 and the second mounting piece 200 can be relatively rotated. In this embodiment, the number of the rotating shafts 530 is two, the left side of the first bracket 540 is connected to the left side of the second bracket 550 through one rotating shaft 530, and the right side of the first bracket 540 is connected to the right side of the second bracket 550 through the other rotating shaft 530.
In another embodiment, the first bracket 540 is provided with a protrusion, the second bracket 550 is provided with a groove, and the protrusion extends into the groove and enables a rotational connection of the first bracket 540 with the second bracket 550.
It should be noted that, the second bracket 550 can rotate forward and backward with respect to the first bracket 540; the first connecting piece 510 is movably matched with the first bracket 540, when the second bracket 550 rotates forward relative to the first bracket 540, the transmission unit is used for enabling the first connecting piece 510 to be close to the switching position, and when the second bracket 550 rotates reversely relative to the first bracket 540, the transmission unit is used for enabling the first connecting piece 510 to be far away from the switching position; and/or the second connecting member 520 cooperates with the second bracket movement 550, the transmission unit is configured to move the second connecting member 520 closer to the junction when the second bracket 550 is rotated forward relative to the first bracket 540, and the transmission unit is configured to move the second connecting member 520 away from the junction when the second bracket 550 is rotated backward relative to the first bracket 540.
In particular, in this embodiment, the first connecting member 510 is movably engaged with the first bracket 540, and the transmission unit is configured to move the first connecting member 510 closer to the junction when the second bracket 550 is rotated forward relative to the first bracket 540, and move the first connecting member 510 away from the junction when the second bracket 550 is rotated backward relative to the first bracket 540; and the second connecting piece 520 is matched with the second bracket moving 550, when the second bracket 550 rotates forward relative to the first bracket 540, the transmission unit is used for enabling the second connecting piece 520 to be close to the switching position, and when the second bracket 550 rotates reversely relative to the first bracket 540, the transmission unit is used for enabling the second connecting piece 520 to be far away from the switching position.
In particular, in the application scenario of the connection assembly 500 in the first embodiment, when the second bracket 550 rotates forward relative to the first bracket 540, that is, the display screen rotates toward the back of the first display element 300 or the second display element 400, the first connection member 510 and the second connection member 520 both move toward the junction near the first bracket 540 and the second bracket 550, so that the gap between the first display element 300 and the second display element 400 is reduced, the display effect is ensured, and when the second bracket 550 rotates reversely relative to the first bracket 540, that is, the display screen rotates toward the front of the first display element 300 or the second display element 400, the first connection member 510 and the second connection member 520 both move toward the junction far away from the first bracket 540 and the second bracket 550, so that the gap between the first display element 300 and the second display element 400 is increased.
It should be noted that, if the first display element 300 and the second display element 400 are connected by using a conventional rotating connection member such as a rotating shaft or a hinge, when the display screen rotates toward the front of the first display element 300 or the second display element 400, as the rotation amplitude of the second display element 400 relative to the first display element 300 is larger, the first display element 300 and the second display element 400 collide with each other and cannot rotate, and when the second bracket 550 rotates reversely relative to the first bracket 540, the second connection member 520 can pull the second display element 400 away from the first display element 300 to move, and the first connection member 510 can pull the first display element 300 away from the second display element 400, so that a gap is left between the first display element 300 and the second display element 400 to allow the second display element 400 to rotate within a moving range.
As shown in fig. 7 and 8, the transmission unit further includes a first guide portion 511 provided on the first connector 510, a second guide portion 554 provided on the second bracket 550, a third guide portion 512 provided on the first connector 510, a fourth guide portion 541 provided on the first bracket 540, a fifth guide portion 522 provided on the second connector 520, and a sixth guide portion 551 provided on the second bracket 550, the first guide portion 511 being in guide engagement with the second guide portion 554, the third guide portion 512 being in guide engagement with the fourth guide portion 541, and the fifth guide portion 522 being in guide engagement with the sixth guide portion 551;

In this manner, when the second bracket 550 is rotated forward with respect to the first bracket 540, the width of the gap 10 formed between the first display element 300 and the second display element 400 may be made to have a tendency to be reduced. When the second bracket 550 is reversely rotated with respect to the first bracket 540, the first guide portion 511 can be moved under the guide of the second guide portion 554 so that the third guide portion 512 is far from the transfer portion under the guide of the fourth guide portion 541 and the fifth guide portion 522 is far from the transfer portion under the guide of the sixth guide portion 551. In this manner, when the second bracket 550 is reversely rotated with respect to the first bracket 540, the width of the gap 10 formed between the first display element 300 and the second display element 400 may be increased.

As shown in fig. 11 to 16, the connection assembly 500 includes a first bracket 540, a second bracket 550, a first connection member 510, a second connection member 520, and a transmission unit, wherein the first bracket 540 is rotatably connected with the second bracket 550, the first connection member 510 is connected with the first bracket 540, and the second connection member 520 is connected with the second bracket 550; when the first connecting member 510 is movably engaged with the first bracket 540 and the second bracket 550 is rotated relative to the first bracket 540, the transmission unit is used to make the first connecting member 510 approach to the junction between the first bracket 540 and the second bracket 550. The first connector 510 is for connection with the first mounting member 100, and the second connector 520 is for connection with the second mounting member 200. It is understood that the first connector 510 may also be directly connected to the first display element 300, and the second connector 520 may be directly connected to the second display element 400.
When the above-mentioned connection assembly 500 is applied to a connection structure of a display screen, the first mounting member 100 is used for mounting the first display element 300, the first display element 300 may be separated from the first mounting member 100 to implement quick maintenance and replacement, the second mounting member 200 is used for mounting the second display element 400, the second display element 400 may be separated from the second mounting member 200 to implement quick maintenance and replacement, and since the first mounting member 100 and the second mounting member 200 are arranged in parallel, after the first display element 300 and the second display element 400 are mounted, the first display element 300 and the second display element 400 may form a parallel structure. It is understood that the first connecting member 510 may be directly connected to the first display element 300, and the second connecting member 520 may be directly connected to the second display element 400, so that the first display element 300 and the second display element 400 form a parallel structure when the first display element 300 and the second display element 400 are assembled. The first display element 300 and the second display element 400 are connected together through the connection assembly 500, when the second bracket 550 and the first bracket 540 rotate relatively, the second display element 400 rotates along with the second bracket 550 relative to the first display element 300, so that the first display element 300 and the second display element 400 form a curved structure, and when the display screen adopts the above connection structure, the display screen also has a curved function correspondingly; and the first display element 300 and the second display element 400 are connected together through the connecting assembly 500, when the second bracket 550 rotates relative to the first bracket 540, the transmission unit can make the second connecting piece 520 approach to the junction between the first bracket 540 and the second bracket 550, so as to pull the second display element 400 to move towards the first display element 300, so that the gap between the first display element 300 and the second display element 400 has a reduced tendency.
It should be noted that, if the first display element 300 and the second display element 400 are connected by using a conventional rotating connection member such as a rotating shaft or a hinge, when the display screen rotates toward the back of the first display element 300 and the second display element 400, as the rotation width of the second display element 400 relative to the first display element 300 increases, the width of the gap 10 formed between the first display element 300 and the second display element 400 increases, and by using the connecting assembly 500 of the present application to connect the first display element 300 and the second display element 400, when the second display element 400 rotates relative to the first display element 300, the second connection member 520 can pull the second display element 400 toward the first display element 300, the width of the gap 10 between the first display element 300 and the second display element 400 does not increase or increases very little within a certain rotation range, and the width of the gap 10 formed between the first display element 300 and the second display element 400 has a tendency to decrease, so that the width of the gap 10 formed between the first display element 300 and the second display element 400 does not indicate that the width of the display screen between the first display element 300 and the second display element 400 indicates that the gap 10 between the first display element 300 and the second display element 400 is larger than the width of the first display element 400, and the gap between the first display element 400 and the second display element 400 can actually decrease because the width of the gap between the first display element 300 and the second display element 400 indicates that the gap between the first display element 300 and the gap and the first display element 400 and the gap between the first display element 300 and the gap between the first display element and the first display element 400 and the gap has a larger trend to be larger.
Of course, in the above-mentioned connection structure, the second connection member 520 may also be movably matched with the second bracket 550, and the transmission unit is used to make the second connection member 520 approach to the junction between the first bracket 540 and the second bracket 550 when the second bracket 550 and the first bracket 540 rotate relatively.

In this manner, the second mounting member 200 is pulled to move toward the first mounting member 100 by the second connecting member 520, and the first connecting member 510 pulls the first mounting member 100 to move toward the second mounting member 200, so that the first mounting member 100 and the second mounting member 200 are close to each other, and the width of the gap 10 formed between the first display element 300 and the second display element 400 is more remarkably reduced.
It should be noted that, the first display element 300 and the second display element 400 may be LED display modules, and the first mounting member 100 and the second mounting member 200 are both frame-shaped structures.
As shown in fig. 11-16, in the second embodiment, the connection assembly 500 further includes a rotation shaft 530, and the first bracket 540 and the second bracket 550 are rotatably connected by the rotation shaft 530. Specifically, the first bracket 540 is provided with a first assembly hole, the second bracket 550 is provided with a second assembly hole, and the rotating shaft 530 is inserted into the first assembly hole and the second assembly hole. The rotating shaft 530 is used for enabling the first bracket 540 and the second bracket 550 to be rotationally connected, and because the first bracket 540 is movably matched with the first connecting piece 510, the first connecting piece 510 is connected with the first mounting piece 100, the second bracket 550 is movably matched with the second connecting piece 520, the second connecting piece 520 is connected with the second mounting piece 200, and when the first bracket 540 and the second bracket 550 are relatively rotated by means of the rotating shaft 530, the first mounting piece 100 and the second mounting piece 200 can be relatively rotated.
In another embodiment, the first bracket 540 is provided with a protrusion, the second bracket 550 is provided with a groove, and the protrusion extends into the groove and enables a rotational connection of the first bracket 540 with the second bracket 550.
It should be noted that, the second bracket 550 can rotate forward and backward with respect to the first bracket 540; the first connecting piece 510 is movably matched with the first bracket 540, when the second bracket 550 rotates forward relative to the first bracket 540, the transmission unit is used for enabling the first connecting piece 510 to be close to the switching position, and when the second bracket 550 rotates reversely relative to the first bracket 540, the transmission unit is used for enabling the first connecting piece 510 to be far away from the switching position; and/or the second connecting member 520 cooperates with the second bracket movement 550, the transmission unit is configured to move the second connecting member 520 closer to the junction when the second bracket 550 is rotated forward relative to the first bracket 540, and the transmission unit is configured to move the second connecting member 520 away from the junction when the second bracket 550 is rotated backward relative to the first bracket 540.
As shown in fig. 13-16, further, the transmission unit includes a first transmission wheel 560 fixedly connected to the second support 550, and a first transmission part 513 disposed on the first connecting member 510, where the first transmission part 513 is in transmission fit with the first transmission wheel 560, and when the second support 550 rotates relative to the first support 540, the first transmission wheel 560 can drive the first connecting member 510 to approach the transition point (M direction in fig. 16) through the first transmission part 513. The first driving wheel 560 can rotate along with the rotation of the second bracket 550, and because the first driving wheel 560 is in transmission fit with the first transmission part 513, when the second bracket 550 and the first bracket 540 rotate relatively, the first driving wheel 560 can drive the first connecting piece 510 to move towards the junction of the first bracket 540 and the second bracket 550. It should be noted that, when the second bracket 550 rotates in the opposite direction, the first driving wheel 560 can drive the first connecting member 510 to move in a direction away from the junction between the first bracket 540 and the second bracket 550.
Optionally, the first driving wheel 560 is a first gear fixedly connected to the second bracket 550, and the first driving part 513 is a plurality of first teeth, first grooves or first holes on the first connecting member 510 and disposed at intervals along the moving direction of the first connecting member 510, where the first gear is meshed with the first teeth, the first grooves or the first holes. Specifically, the first connecting member 510 is a first rack that is slidably engaged with the first bracket 540, and the first gear is in driving engagement with teeth of the first rack. Thus, when the second bracket 550 and the first bracket 540 rotate relatively, the first gear can rotate along with the second bracket 550, so as to drive the first rack to move. The length direction of the first rack is consistent with the second direction in the first embodiment, and the teeth of the first rack are arranged along the length direction of the first rack. The first driving wheel 560 and the second bracket 550 may be an integral structure, or may be two parts fixed to each other.
Of course, the first driving wheel 560 may also be a wheel with a rough appearance, and when rotating, the first driving wheel can drive the first connecting member 510 to approach or separate from the junction between the first bracket 540 and the second bracket 550.
Further, the transmission unit further includes a second transmission wheel fixedly connected to the first bracket 540, and a second transmission part 523 disposed on the second connection member 520, where the second transmission wheel is in transmission fit with the second transmission part 523, and when the first bracket 540 rotates relative to the second bracket 550, the second transmission wheel can drive the second connection member 520 to approach the switching position (N direction in fig. 16) through the second transmission part 523. The second driving wheel can rotate along with the rotation of the first bracket 540, and because the second driving wheel is in transmission fit with the second transmission part 523, when the second bracket 550 and the first bracket 540 rotate relatively, the second driving wheel can drive the second connecting piece 520 to move towards the junction of the first bracket 540 and the second bracket 550. It should be noted that, when the first bracket 540 rotates in the opposite direction, the second driving wheel can drive the second connecting piece 520 to move in a direction away from the junction between the first bracket 540 and the second bracket 550.
Optionally, the second driving wheel is a second gear fixedly connected to the first bracket 540, and the second driving part 523 is a plurality of second teeth, second grooves or second holes on the second connecting member 520, which are arranged at intervals along the moving direction of the second connecting member 520, and the second gear is meshed with the second teeth, the second grooves or the second holes. Thus, when the first rack 540 rotates relative to the second rack 550, the second gear can rotate the first rack 540, thereby driving the second rack to move. The second transmission portion 523 is a tooth on the second rack, and the length direction of the second rack is consistent with the third direction in the first embodiment, and the teeth of the second rack are arranged along the length direction of the second rack. The second driving wheel and the first bracket 540 may be an integral structure, or may be two parts fixed to each other.
Of course, the second driving wheel may also be a wheel with a rough appearance, and when rotating, the second driving wheel can drive the second connecting piece 520 to approach or separate from the junction between the first bracket 540 and the second bracket 550.
In this embodiment, the first driving wheel 560 and the second driving wheel are gears, the first driving wheel 560 and the second driving wheel are opposite, the rotating shaft 530 is rotatably arranged in the first driving wheel 560 and the second driving wheel, the first connecting piece 510 is a first rack, the second connecting piece 520 is a second rack, and when the first bracket 540 and the second bracket 550 are rotated relatively, the first driving wheel 560 and the second driving wheel can respectively drive the first rack and the second rack to move, so that the first rack and the second rack are close to each other, and the width of the gap 10 formed between the first display element 300 and the second display element 400 is more obviously reduced.
Referring to fig. 11-16, in the second embodiment, the first connecting member 510 is slidably engaged with the first support 540, and the first connecting member 510 can move relative to the first support 540 in a direction approaching or moving away from the junction between the first support 540 and the second support 550; the first connecting member 510 is slidably engaged with the first bracket 540, such that when the first bracket 540 and the second bracket 550 rotate around the rotation axis 530, the first connecting member 510 moves relative to the first bracket 540 in a direction approaching the junction between the first bracket 540 and the second bracket 550, thereby pulling the first mounting member 100 to move toward the second mounting member 200, so that the width of the gap 10 formed between the first display element 300 and the second display element 400 tends to be reduced. Of course, the first connecting member 510 and the first bracket 540 may be connected in a rolling manner by a connecting member such as a roller.
Further, the second connector 520 is slidably engaged with the second bracket 550, and the second connector 520 can move relative to the second bracket 550 in a direction approaching or moving away from the junction between the first bracket 540 and the second bracket 550. The second connector 520 is slidably engaged with the second bracket 550, such that when the first bracket 540 and the second bracket 550 rotate around the rotation axis 530, the second connector 520 moves relative to the second bracket 550 in a direction approaching the junction between the first bracket 540 and the second bracket 550, thereby pulling the second mounting member 200 to move toward the first mounting member 100, so that the width of the gap 10 formed between the first display element 300 and the second display element 400 tends to be reduced. Of course, the second connecting member 520 and the second bracket 550 may be connected in a rolling manner by a connecting member such as a roller.
In this embodiment, the first connecting member 510 is slidably engaged with the first bracket 540, and the second connecting member 520 is slidably engaged with the second bracket 550, so that the connection mode of the first connecting member 510 and the first bracket 540 is consistent with the connection mode of the second connecting member 520 and the second bracket 550, which is beneficial to the stable operation of the mechanism.

The first connector 510 is for connection with the first mounting member 100, and the second connector 520 is for connection with the second mounting member 200. It is understood that the first connector 510 may also be directly connected to the first display element 300, and the second connector 520 may be directly connected to the second display element 400.
When the above-mentioned connection assembly 500 is applied to a connection structure of a display screen, the first mounting member 100 is used for mounting the first display element 300, the first display element 300 may be separated from the first mounting member 100 to implement quick maintenance and replacement, the second mounting member 200 is used for mounting the second display element 400, the second display element 400 may be separated from the second mounting member 200 to implement quick maintenance and replacement, and since the first mounting member 100 and the second mounting member 200 are arranged in parallel, after the first display element 300 and the second display element 400 are mounted, the first display element 300 and the second display element 400 may form a parallel structure. It is understood that the first connecting member 510 may be directly connected to the first display element 300, and the second connecting member 520 may be directly connected to the second display element 400, so that the first display element 300 and the second display element 400 form a parallel structure when the first display element 300 and the second display element 400 are assembled. The first display element 300 and the second display element 400 are connected together through the connection assembly 500, when the second bracket 550 and the first bracket 540 rotate relatively, the second display element 400 rotates along with the second bracket 550 relative to the first display element 300, so that the first display element 300 and the second display element 400 form a curved structure, and when the display screen adopts the above connection structure, the display screen also has a curved function correspondingly; and the first display element 300 and the second display element 400 are connected together through the connecting assembly 500, when the second bracket 550 rotates relative to the first bracket 540, the transmission unit can make the second connecting piece 520 approach to the junction between the first bracket 540 and the second bracket 550, so as to pull the second display element 400 to move towards the first display element 300, so that the gap between the first display element 300 and the second display element 400 has a reduced tendency.
It should be noted that, if the first display element 300 and the second display element 400 are connected by using a conventional rotating connection member such as a rotating shaft or a hinge, when the display screen rotates toward the back of the first display element 300 and the second display element 400, as the rotation width of the second display element 400 relative to the first display element 300 increases, the width of the gap 10 formed between the first display element 300 and the second display element 400 increases, and by using the connecting assembly 500 of the present application to connect the first display element 300 and the second display element 400, when the second display element 400 rotates relative to the first display element 300, the second connection member 520 can pull the second display element 400 toward the first display element 300, the width of the gap 10 between the first display element 300 and the second display element 400 does not increase or increases very little within a certain rotation range, and the width of the gap 10 formed between the first display element 300 and the second display element 400 has a tendency to decrease, so that the width of the gap 10 formed between the first display element 300 and the second display element 400 does not indicate that the width of the display screen between the first display element 300 and the second display element 400 indicates that the gap 10 between the first display element 300 and the second display element 400 is larger than the width of the first display element 400, and the gap between the first display element 400 and the second display element 400 can actually decrease because the width of the gap between the first display element 300 and the second display element 400 indicates that the gap between the first display element 300 and the gap and the first display element 400 and the gap between the first display element 300 and the gap between the first display element and the first display element 400 and the gap has a larger trend to be larger.
Of course, in the above-mentioned connection structure, the second connection member 520 may also be movably matched with the second bracket 550, and the transmission unit is used to make the second connection member 520 approach to the junction between the first bracket 540 and the second bracket 550 when the second bracket 550 and the first bracket 540 rotate relatively.
In particular, in this embodiment, in the connection structure, the first connecting member 510 is movably matched with the first bracket 540, the second connecting member 520 is movably matched with the second bracket 550, and when the second bracket 550 and the first bracket 540 rotate relatively, the transmission unit is used to make the first connecting member 510 approach to the junction between the first bracket 540 and the second bracket 550, and the transmission unit is also used to make the second connecting member 520 approach to the junction between the first bracket 540 and the second bracket 550. In this manner, the second mounting member 200 is pulled to move toward the first mounting member 100 by the second connecting member 520, and the first connecting member 510 pulls the first mounting member 100 to move toward the second mounting member 200, so that the first mounting member 100 and the second mounting member 200 are close to each other, and the width of the gap 10 formed between the first display element 300 and the second display element 400 is more remarkably reduced.
It should be noted that, the first display element 300 and the second display element 400 may be LED display modules, and the first mounting member 100 and the second mounting member 200 are both frame-shaped structures.
As shown in fig. 17-18, in the third embodiment, the connection assembly 500 further includes a rotation shaft 530, and the first bracket 540 and the second bracket 550 are rotatably connected by the rotation shaft 530. Specifically, the first bracket 540 is provided with a first assembly hole, the second bracket 550 is provided with a second assembly hole, and the rotating shaft 530 is inserted into the first assembly hole and the second assembly hole. The rotating shaft 530 is used for enabling the first bracket 540 and the second bracket 550 to be rotationally connected, and because the first bracket 540 is movably matched with the first connecting piece 510, the first connecting piece 510 is connected with the first mounting piece 100, the second bracket 550 is movably matched with the second connecting piece 520, the second connecting piece 520 is connected with the second mounting piece 200, and when the first bracket 540 and the second bracket 550 are relatively rotated by means of the rotating shaft 530, the first mounting piece 100 and the second mounting piece 200 can be relatively rotated.
In another embodiment, the first bracket 540 is provided with a protrusion, the second bracket 550 is provided with a groove, and the protrusion extends into the groove and enables a rotational connection of the first bracket 540 with the second bracket 550.
In the third embodiment, the transmission unit includes a first elastic compression member 570, one end of the first elastic compression member 570 abuts against the first bracket 540, the other end of the first elastic compression member 570 abuts against the first connection member 510, and the first elastic compression member 570 is used to make the first connection member 510 have a tendency to move toward the junction between the first bracket 540 and the second bracket 550. The first elastic compression member 570 is always kept in a compressed state, and during the rotation of the first support 540 around the rotation axis 530, the distance between the first support 540 and the rotation axis 530 is kept constant, but under the action of the first elastic compression member 570, the first connection member 510 is always subjected to the pushing force of the first elastic compression member 570, so that the first connection member 510 has a tendency to move toward the junction between the first support 540 and the second support 550 (the direction M in fig. 18), thereby the width of the gap 10 formed between the first display element 300 and the second display element 400 has a tendency to be reduced.
Alternatively, the first elastic compression member 570 may be a spring, a shrapnel, or elastic rubber, etc.
Further, the first connecting member 510 is provided with a first protrusion 514, the first bracket 540 is provided with a first abutment block 542 opposite to the first protrusion 514, the first abutment block 542 is located at one side of the first protrusion 514 away from the second mounting member 200, and two ends of the first elastic compression member 570 are respectively abutted against the first protrusion 514 and the first abutment block 542. Since the first elastic compression member 570 is disposed between the first protrusion 514 and the first abutment block 542, and the first abutment block 542 is located at a side of the first protrusion 514 away from the second mounting member 200, the first elastic compression member 570 is always capable of providing a pushing force to the first protrusion 514, such that the first connection member 510 has a tendency to move toward the second mounting member 200.
Specifically, the first connection member 510 is stacked with the first bracket 540, and the first connection member 510 is provided with a first opening 543, and the first abutment block 542 passes through the first opening 543 and is spaced apart from the first protrusion 514. The first abutting block 542 extends from one side of the first connecting piece 510, which is close to the first bracket 540, to one side, which is away from the first bracket 540, through the first opening 543, so that the first protrusion 514 is opposite to the first abutting block 542 in a spaced manner, and the occupied space of the connecting structure in the first direction can be reduced, and the size is smaller.
In the third embodiment, the first connecting member 510 is slidably engaged with the first bracket 540, and the first connecting member 510 can move relative to the first bracket 540 in a direction approaching or moving away from the junction between the first bracket 540 and the second bracket 550. Thus, when the first bracket 540 and the second bracket 550 rotate around the rotation axis 530, the first connecting member 510 moves relative to the first bracket 540 in a direction approaching the junction between the first bracket 540 and the second bracket 550 under the action of the first elastic compression member 570, so as to pull the first mounting member 100 to move towards the second mounting member 200, such that the width of the gap 10 formed between the first display element 300 and the second display element 400 tends to be reduced. Of course, the first connecting member 510 and the first bracket 540 may be connected in a rolling manner by a connecting member such as a roller.
In the third embodiment, the connection assembly 500 further includes a second elastic compression member 580, one end of the second elastic compression member 580 abuts against the second bracket 550, the other end of the second elastic compression member 580 abuts against the second connection member 520, and the second elastic compression member 580 is configured to cause the second connection member 520 to have a tendency to move toward the junction between the first bracket 540 and the second bracket 550 (N direction in fig. 18). The second elastic compression member 580 is always kept in a compressed state, and the distance between the second bracket 550 and the rotating shaft 530 is kept constant during the rotation of the second bracket 550 around the rotating shaft 530, but under the action of the second elastic compression member 580, the second connection member 520 is always subjected to the pushing force of the second elastic compression member 580, so that the second connection member 520 has a tendency to move toward the junction between the first bracket 540 and the second bracket 550, thereby reducing the width of the gap 10 formed between the first display element 300 and the second display element 400.
