Description

Technical Field

[0001] This invention relates to the field of displays, and more particularly to a splicing device and a splicing display equipment. Background Technology

[0002] In some work settings, a single screen is insufficient to meet the needs of the job. In such cases, it is necessary to combine multiple screens. After multiple screens are combined and spliced ​​together to form a single screen combination, more information can be conveyed, which can meet the needs of real-time monitoring, command and dispatch, reporting and display, advertising and other aspects.

[0003] Currently, splicing components for combining multiple screens have appeared on the market. However, existing screen splicing components are generally splicing brackets. These brackets replace the original screen supports and are connected to the middle of the back shells of two adjacent display screens. The installation space required is relatively large. Moreover, existing splicing brackets include multi-jointed cantilever arms, which are relatively complex in structure and expensive. After adjusting the angle between the two display screens, it is necessary to manually adjust the distance between the two adjacent display screens. In fact, to prevent mechanical interference, the operation of increasing the distance between the two adjacent display screens is added before adjusting the angle.

[0029] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0030] Certain terms are used in the specification and claims to refer to specific elements. It will be understood by those skilled in the art that manufacturers may use different names to refer to the same element. This specification and claims do not distinguish elements by differences in name, but rather by differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to".

[0031] Please see Figures 1-2 This is a schematic diagram of a splicing device 1 proposed in an embodiment of the present invention for use in a splicing display device having a first display screen 2 and a second display screen 3.

[0032] The splicing device 1 mentioned above includes a first joining mechanism 10, such as Figure 4 As shown, the first engagement mechanism 10 includes a first positioning member 106, a second positioning member 108, and a guide member 102. The guide member 102 has a first guide groove 104 and a second guide groove 107. The first positioning member 106 is connected to the first display screen 2 and is movably disposed within the first guide groove 104. The second positioning member 108 is connected to the second display screen 3 and is movably disposed within the second guide groove 107.

[0033] When splicing the first display screen 2 and the second display screen 3, the position of the first positioning member 106 in the first guide groove 104 is adjusted to adjust the angle of the first display screen 2, and the position of the second positioning member 108 in the second guide groove 107 is adjusted to adjust the angle of the second display screen 3. An angle is formed between the first display screen 2 and the second display screen 3, so that the first display screen 2 and the second display screen 3 are spliced ​​at a set angle to form an integral screen combination. The splicing device 1 proposed in this invention has a simple structure and occupies little space. While joining two adjacent display screens 2 and 3, it can quickly adjust the angle between the two display screens 2 and 3. In actual use, the splicing device 1 is preferably installed on the adjacent side of the two display screens 2 and 3. During the adjustment of the angle between the two display screens 2 and 3, the size of the gap formed between the display screens 2 and 3 changes very little, or remains unchanged, or maintains a seamless contact. It can be adjusted in one go, with high splicing efficiency. Unlike the splicing bracket connected to the middle of the back shell 32 in the prior art, it is not necessary to adjust the distance between the two adjacent display screens 2 and 3 after adjusting the angle of the two display screens 2 and 3.

[0034] In one embodiment, reference Figures 5-6 As shown, the first guide groove 104 and the second guide groove 107 are preferably arc-shaped grooves. The normal direction A1 of the first guide groove 104 forms an acute angle with the angle bisector D of the angle between the two display screens 2 and 3, and the normal direction A2 of the second guide groove 107 also forms an acute angle with the angle bisector D of the angle between the two display screens 2 and 3. Furthermore, the first guide groove 104 and the second guide groove 107 are preferably symmetrically arranged, sharing a common center on the angle bisector D. In a further preferred embodiment, in practical applications, the front corners of the first display screen 2 and the second display screen 3 are arranged to abut against each other, and the centers of the circles corresponding to the first guide groove 104 and the second guide groove 107 are located at the front corners of the two display screens. In this case, during the adjustment of the angle between the first display screen 2 and the second display screen 3, the front corners of the first display screen 2 and the second display screen 3 remain abutted, and there is no gap between the first display screen 2 and the second display screen 3. The abutment stress is small, and the picture display effect is better.

[0035] In one embodiment, the first positioning member 106 has a first protrusion 105, which is engaged in and slidably adapted to the first guide groove 104. The second positioning member 108 has a second protrusion 110, which is engaged in and slidably adapted to the second guide groove 107. Please refer to... Figure 7In one embodiment, the splicing device 1 further includes a first connector 114 and a second connector 115. The first connector 114 is used to movably fix the guide 102 onto the first display screen 2. One end of the first connector 114 is connected to the first positioning member 106, and the size of the other end is larger than the size of the first guide groove 104, thereby confining the guide 102 between the first display screen 2 and the first connector 114. The second connector 115 is used to movably fix the guide 102 onto the second display screen 3. One end of the second connector 115 is connected to the second positioning member 108, and the size of the other end is larger than the size of the second guide groove 107, thereby confining the guide 102 between the second display screen 3 and the second connector 115, preventing the guide 102 from falling off, and improving structural reliability.

[0036] In the above embodiment, the user can push or pull at least one of the first display screen 2 and the second display screen 3 to make them form an angle relative to each other. Under this operation, the first positioning member 106 and the second positioning member 108 of the splicing device 1 will change position relative to the first guide groove 104 and the second guide groove 107, respectively.

[0037] In a preferred embodiment, the splicing device 1 further includes a push-pull member 101, which is connected to both the first positioning member 106 and the second positioning member 108. Moving the push-pull member 101 can adjust the position of the first positioning member 106 in the first guide groove 104 and the position of the second positioning member 108 in the second guide groove 107. Preferably, the first guide groove 104 and the second guide groove 107 are symmetrically arranged arc-shaped grooves. When the push-pull member 101 is pushed, such as... Figures 5-6 As shown, the first positioning component 106 changes position relative to the first guide groove 104, causing the first display screen 2 to rotate. The second positioning component 108 changes position relative to the second guide groove 107, causing the second display screen 3 to rotate. The two display screens form an angle relative to each other, which can be adjusted into place in one go. The operation is simple and the splicing efficiency is high.

[0038] In one embodiment, the push-pull member 101 further includes a third guide groove 112 and a fourth guide groove 113. The first positioning member 106 passes through the third guide groove 112, and the third guide groove 112 intersects the first guide groove 104 at an angle other than 90 degrees. The second positioning member 108 passes through the fourth guide groove 113, and the fourth guide groove 113 intersects the second guide groove 107 at an angle other than 90 degrees. For example, the third guide groove 112 extends along the -X-axis direction, and the fourth guide groove 113 extends along the X-axis direction. Since the third guide groove 112 intersects the first guide groove 104 at an angle other than 90 degrees, and the fourth guide groove 113 intersects the second guide groove 107 at an angle other than 90 degrees, when the push-pull member 101 is pulled along the Y-axis direction, as... Figure 5 As shown, the first positioning member 106 moves along the -X-axis direction in the first guide groove 104, and the second positioning member 108 moves along the X-axis direction in the second guide groove 107. The first display screen 2 and the second display screen 3 form an angle relative to each other. When the push-pull member 101 is pulled along the -Y-axis direction, as... Figure 6 As shown, the first positioning member 106 moves along the X-axis in the first guide groove 104, and the second positioning member 108 moves along the -X-axis in the second guide groove 107, so that the angle between the first display screen 2 and the second display screen 3 gradually approaches 180°.

[0039] In one embodiment, the guide member 102 is provided with a sliding groove. One end of the push-pull member 101 is connected to the first positioning member 106 and the second positioning member 108, and the other end of the push-pull member 101 is received in the sliding groove. The push-pull member 101 is slidably adapted to the sliding groove. When the push-pull member 101 is pushed to slide in the sliding groove, the first positioning member 106 moves in the first guide groove 104 to adjust the rotation angle of the first display screen 2, and the second positioning member 108 moves in the second guide groove 107 to adjust the rotation angle of the second display screen 3, so as to quickly change the angle between the first display screen 2 and the second display screen 3.

[0040] In a preferred embodiment, the guide groove includes a first slide groove 103 and a second slide groove 109. Both the first slide groove 103 and the second slide groove 109 extend along the Y-axis and are symmetrically arranged. The first guide groove 104 and the second guide groove 107 are also symmetrically arranged, as are the third guide groove 112 and the fourth guide groove 113. When the push-pull member 101 is pushed along the Y-axis, it slides in the first slide groove 103 and the second slide groove 109. The first positioning member 106 moves in the first guide groove 104, adjusting the angle between the first display screen 2 and the Y-axis. The second positioning member 108 moves in the second guide groove 107, adjusting the angle between the second display screen 3 and the Y-axis. At this time, the angle between the first display screen 2 and the Y-axis is the same as the angle between the second display screen 3 and the Y-axis, achieving symmetrical adjustment of the angles between the two display screens relative to the Y-axis. This method is simple to operate and convenient for users.

[0041] In one embodiment, the push-pull member 101 further includes a handle 111. Pushing the handle 111 causes the push-pull member 101 to move in the slide to adjust the rotation angle between the first display screen 2 and the second display screen 3. The angle between the first display screen 2 and the second display screen 3 can be adjusted simply by moving the handle 111. The overall structure is relatively simple, easy to operate, and convenient for users.

[0042] In a preferred embodiment, the handle 111 has a top and two oppositely arranged sides. One side connects the top and the third guide groove 112, and the other side connects the top and the fourth guide groove 113. Preferably, one side of the handle 111 passes through the first slide groove 103 of the guide member 102 and is slidably adapted to the first slide groove 103. Preferably, the other side of the handle 111 passes through the second slide groove 109 of the guide member 102 and is slidably adapted to the second slide groove 109.

[0043] The first guide groove 104 is located between the top of the third guide groove 112 and the handle 111, and the second guide groove 107 is located between the top of the fourth guide groove 113 and the handle 111. Pushing the handle 111 causes it to move simultaneously in the first slide groove 103 and the second slide groove 109. At this time, the third guide groove 112 pushes against the first positioning member 106, causing the first positioning member 106 to move in the first guide groove 104. Simultaneously, the fourth guide groove 113 pushes against the second positioning member 108, causing the second positioning member 108 to move in the second guide groove 107, thereby adjusting the angle between the first display screen 2 and the second display screen 3.

[0044] In one embodiment, the top of the handle 111 is provided with a first through hole and a second through hole. The first through hole is correspondingly provided with the first positioning member 106, and the second through hole is correspondingly provided with the second positioning member 108. By providing the first through hole and the second through hole, it is convenient to operate the first positioning member 106 and the second positioning member 108.

[0045] In another embodiment, the third guide groove 112 may also be located between the first guide groove 104 and the top of the handle 111, and the fourth guide groove 113 may be located between the second guide groove 107 and the top of the handle 111. In other embodiments, along the Y-axis direction, the handle 111 may also be located relative to the front or rear of the third / fourth guide groove. In this case, the guidance of the movement direction of the handle 111 can be achieved by means of the sliding groove provided on the push-pull member 101 and the mating member provided on the guide member 102, which will not be described in detail here.

[0046] In one embodiment, the splicing device 1 further includes a second joining mechanism 11, wherein the first joining mechanism 10 and the second joining mechanism 11 are disposed opposite to each other. The first joining mechanism 10 is preferably disposed at the top of the two display screens; in other words, as... Figure 7 As shown, the first positioning member 106 of the first joining mechanism 10 is located at the upper right corner of the first display screen 2, and the second positioning member 108 of the first joining mechanism 10 is located at the upper left corner of the second display screen 3. The second joining mechanism 11 is preferably located at the bottom of the two screens.

[0047] In one embodiment, the splicing device 1 further includes a second joining mechanism 11, such as... Figure 3 As shown, the second joining mechanism 11 has the same structure as the first joining mechanism 10. The first joining mechanism 10 and the second joining mechanism 11 are arranged opposite to each other and symmetrically. The first joining mechanism 10 is preferably located at the top of the two display screens, and the second joining mechanism 11 is preferably located at the bottom of the two screens. In actual use, the angle between the first display screen 2 and the second display screen 3 can be adjusted synchronously by adjusting the first joining mechanism 10 and the second joining mechanism 11, and the gap between the first display screen 2 and the second display screen 3 will not change during adjustment. The first joining mechanism 10 and the second joining mechanism 11 ensure that the sides of the first display screen 2 and the second display screen 3 always remain parallel to each other, and are not easily deformed, so as not to affect the display effect after the first display screen 2 and the second display screen 3 are spliced. The user can operate the push-pull component in the first joining mechanism 10 and the push-pull component in the second joining mechanism 20 at the same time to adjust the angle between the two display screens 2 and 3 as a whole. In other embodiments, the first engagement mechanism 10 and the second engagement mechanism may be different. For example, the first engagement mechanism 10 has a push-pull member, while the second engagement mechanism 20 does not have a push-pull member, etc. The present invention is not limited thereto.

[0048] In one embodiment, the splicing device 1 further includes a telescopic member 12, one end of which is movably connected to the first joining mechanism 10, and the other end of which is movably connected to the second joining mechanism 11. When the first joining mechanism 10 is located at the top of the two display screens and the second joining mechanism 11 is located at the bottom of the two display screens, the distance between the first joining mechanism 10 and the second joining mechanism 11 can be adjusted due to the telescopic member 12, thereby enabling the splicing device 1 to be suitable for splicing display screens of different sizes.

[0049] In other embodiments, the telescopic member 12 may also be fixed to one of the first engagement mechanism 10 and the second engagement mechanism 11; preferably, the telescopic member 12 may also be fixedly connected to the first engagement mechanism 10 or the second engagement mechanism 11 or integrally formed with one of the components of the first engagement mechanism 10 and the second engagement mechanism 11, for example, integrally formed with the guide member 102.

[0050] This invention also proposes a splicing display device, which includes a first display screen 2, a second display screen 3, and the aforementioned splicing device 1. The first display screen 2 and the second display screen 3 are arranged adjacent to each other. A first positioning member 106 is connected to the first display screen 2, and a second positioning member 108 is connected to the second display screen 3. The first positioning member 106 is movably inserted into a first guide groove 104, and the second positioning member 108 is movably inserted into a second guide groove 107. Adjusting the position of the first positioning member 106 in the first guide groove 104 and the position of the second positioning member 108 in the second guide groove 107 in the splicing device 1 can drive the first display screen 2 and the second display screen 3 to rotate, quickly adjusting the angle between them.

[0051] In one embodiment, both the first display screen 2 and the second display screen 3 include a display screen 31, a housing, and a support base 34. The housing surrounds the display screen 31 and includes a front bezel and a back shell 32. The support base 34 supports the display screen 31. A through slot 33 is formed in the back shell 32, and one end of the support base 34 passes through the back shell 32, allowing the back shell 32 to rotate around the support base 34. The horizontal dimension of the through slot 33 is larger than the horizontal dimension of the support base 34. When the first display screen 2 and the second display screen 3 are spliced ​​together, forming an angle between them, the back cover 32 rotates, and the groove wall of the through groove 33 on the back cover 32 does not abut against the support base 34. Thus, when adjusting the angle between the first display screen 2 and the second display screen 3, there will be no interference stress between the support base 34 and the back cover 32 due to the angle change, which would cause the back cover 32 to deform, affecting the appearance and the safety of angle adjustment. Furthermore, the position of the support base 34 does not change, and the placement of the support base 34 is not affected. The overall structure is simple and convenient for users to adjust the required angle.

[0052] In one embodiment, both the first display screen 2 and the second display screen 3 may further include a limiting member. The limiting member is fixedly connected to the display screen 1 or 2 and engages in another through slot or groove of the support base 34 to restrict the rotation of the back cover 32 relative to the support base 34, thereby limiting the position of the display screen 31. When only one of the display screens is used, the back cover 32 will not wobble relative to the support base 34. The limiting member can be operated to leave the other through slot or groove, thereby allowing the display screen 1 or 2 to move or rotate relative to the corresponding support base 34. This invention is not limited thereto.

[0053] In summary, the splicing device 1 proposed in this invention can splice adjacent first display screen 2 and second display screen 3, and can quickly adjust the angle between the two display screens as needed while splicing adjacent display screens to form an integrated screen combination. It has a simple structure, does not require replacement of the original mounting bracket during installation, requires less installation space, is easy to operate, and effectively improves the efficiency of screen splicing.

[0054] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
