Abstract
Description
Connecting devices and display equipment Technical Field
[0001] The present invention relates to the field of display technology, and in particular to a connecting device and a display apparatus. Background Art
[0002] With the rapid development of light-emitting diode (LED) display technology, small-pitch or micro-pitch LED displays have become widely used in the high-end display market due to their significantly improved resolution, natural and realistic colors, and seamless splicing capabilities. These displays have reduced the LED pixel pitch to below P2.5, reaching P1.5, P1.0, and even below P1.0, meeting the stringent visual requirements of command and control centers, television studios, high-end conference rooms, and other scenarios.
[0003] When installing LED products with fine or micro pitches, the connecting structure must first be secured to the mounting surface, followed by the LED product itself. This generally requires the mounting surface to have minimal flatness errors, and the connecting structure to maintain high positional accuracy parallel to the mounting surface after installation. Poor flatness on the mounting surface can also lead to poor flatness on the mounting surface of the LED product secured by the connecting structure. Some related technologies utilize spacers to adjust the position of the LED product perpendicular to the mounting surface.

[0082] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure, its application, or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein.

[0086] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0087] When installing LED products with fine or micro pitch, the connecting structure must first be secured to the mounting surface, and then the LED product must be secured to the mounting surface of the connecting structure. This generally requires the mounting surface to have minimal flatness errors, and the connecting structure to be positioned with high precision parallel to the mounting surface after being secured to the mounting surface. Poor flatness on the mounting surface can also lead to poor flatness on the mounting surface of the LED product secured to the connecting structure. Some related technologies use spacers to adjust the position of the LED product perpendicular to the mounting surface.
[0088] If the connection structure has poor positioning accuracy in a direction parallel to the mounting surface after it is installed and fixed on the mounting surface, it may cause uneven gaps between LED products installed on the connection structure, or even make it impossible to install the LED products. However, the gasket in the related art is difficult to meet the requirements for position adjustment of the connection structure in a direction parallel to the mounting surface.
[0089] In view of this, embodiments of the present disclosure provide a connecting device and a display apparatus, which can improve the installation effect of a display panel.
[0090] In one aspect of the present disclosure, there is provided a connecting device for mounting a plurality of display panels on a mounting surface, comprising:
[0091] a base configured to be mounted on the mounting surface;
[0092] a slider movably disposed on the base;
[0093] a first adjustment mechanism connected to the base and the slider, and configured to adjust a position of the slider relative to the base in a first direction;
[0094] a connecting member movably connected to the slider and configured to connect adjacent display panels among the plurality of display panels; and
[0095] a second adjustment mechanism, disposed between the connecting member and the slider, and configured to adjust a position of the connecting member relative to the slider in a second direction;
[0096] The first direction intersects the installation surface, and the second direction intersects the first direction.
[0097] According to this embodiment, the connecting device can realize the installation of multiple display panels on the installation surface, and it realizes the position adjustment of the connecting member connected to the slider in the first direction relative to the base through the movable setting of the slider on the base and the position adjustment effect of the slider by the first adjustment mechanism; the connecting device also realizes the position adjustment of the connecting member in the second direction relative to the base through the movable connection between the slider and the connecting member and the position adjustment effect of the connecting member by the second adjustment mechanism, so that the display panel connected to the connecting member can realize position adjustment in both the first direction and the second direction that intersect with each other, thereby improving the requirements of the display device including multiple display panels for the installation effect of the display panel.
[0098] Figure 1 is a schematic diagram of the installation structure of some embodiments of the display device according to the present disclosure. Figure 2A is a schematic diagram of the exploded structure of some embodiments of the display device according to the present disclosure. Figure 2B is a schematic diagram of the connection between the display panel and the connection device according to some embodiments of the display device according to the present disclosure.
[0099] With reference to Figures 1, 2A, and 2B, embodiments of the present disclosure provide a display device comprising: a bracket 1, multiple display panels 2, and multiple connecting devices CD. The display portion of this display device can be formed by splicing multiple display panels together to meet the needs of large-scale displays in applications such as command and monitoring centers, commercial centers, high-end conferences, and private theaters.
[0100] Bracket 1 is a carrier for supporting multiple display panels 2 and has a mounting surface MS. Bracket 1 can be made of a material with a certain strength and rigidity, such as metal, alloy, plastic, glass, ceramic, or a combination of materials. Bracket 1 can have a frame structure, a solid structure, or a box structure, or a combination of at least two of these structures. Mounting surface MS can be the side surface of bracket 1 in one direction or in two or more directions.
[0101] The plurality of display panels 2 are arranged along at least one direction on the mounting surface MS. The plurality of display panels 2 may be arranged along two directions on the mounting surface MS. For example, the plurality of display panels 2 are arranged in an M*N array, where M>1 and N>1, i.e., the plurality of display panels 2 are arranged along two orthogonal directions parallel to the mounting surface MS. For another example, the plurality of display panels 2 are arranged in a staggered manner of rows and columns, such as in a honeycomb shape, i.e., the plurality of display panels are arranged along two non-orthogonal intersecting directions parallel to the mounting surface MS. In other embodiments, the plurality of display panels 2 may be arranged along a single direction on the mounting surface MS, i.e., the plurality of display panels 2 are arranged in a row or a column.
[0102] Referring to Figure 1 , a first direction dr1 intersects the mounting surface MS, a second direction dr2 intersects the first direction dr1, and a third direction dr3 intersects both the first and second directions dr1 and dr2. In Figure 1 , for a relatively flat mounting surface MS, the first direction dr1 can be perpendicular to the mounting surface MS, the second direction dr2 is perpendicular to the first direction dr1 and is also equivalently parallel to the mounting surface MS, and the third direction dr2 is perpendicular to both the first and second directions dr1 and is also equivalently parallel to the mounting surface. In Figure 1 , multiple display panels 2 are arranged in an array along the second and third directions dr2 and dr3.
[0103] Multiple connecting devices CD are provided on the mounting surface MS and are configured to connect the multiple display panels 2. Each connecting device CD can connect to one or more display panels 2. Connecting devices CD located near the edges or corners of the bracket 1 can only connect to one display panel 2, while connecting devices located elsewhere on the bracket 1 can connect to multiple display panels 2.
[0104] Referring to Figure 1 , multiple connecting devices CD can be arranged similarly to the arrangement of multiple display panels 2, for example, also in an array. For rectangular or substantially rectangular display panels, each connecting device CD can connect the corners of four display panels, achieving close or predetermined spacing between the corners of the four display panels. In Figure 2B , three adjacent display panels 2 are secured to the connecting devices CD at their intersections using screws 21.
[0105] The display panel can use various display panel components capable of achieving light emission or display functions. In some embodiments, the display panel 2 includes a small-pitch light-emitting diode (LED) panel or a micro-pitch light-emitting diode (LED) panel. Here, the pixel pitch of the small-pitch LED panel is less than P2.5, and the pixel pitch of the micro-pitch LED panel is less than P1.0.
[0106] Figure 3 is a schematic diagram of the installation structure of some embodiments of the connection device according to the present disclosure. Figure 4 is a schematic diagram of the exploded structure of some embodiments of the connection device according to the present disclosure. Figure 5 is a schematic diagram of the installation structure of the embodiment shown in Figure 3 from another perspective. Figure 6 is a schematic diagram of a partial cross-section of the embodiment shown in Figure 3.
[0107] With reference to Figures 3-6 , embodiments of the present disclosure provide a connection device CD for mounting multiple display panels 2 on a mounting surface MS. One or more of the multiple connection devices CD described in the aforementioned display device embodiments may employ the connection device CD of this embodiment. The connection device CD is not limited to the aforementioned display device embodiments and may also be used in other scenarios requiring mounting multiple display panels 2 on a mounting surface MS to implement display devices, lighting devices, or other applications.
[0108] The connecting device CD includes a base 3, a slider 4, a first adjustment mechanism 5, a connector 6, and a second adjustment mechanism 7. The base 3 is configured to be mounted on the mounting surface MS. The slider 4 is movably disposed on the base 3. The first adjustment mechanism 5 is connected to the base 3 and the slider 4 and is configured to adjust the position of the slider 4 relative to the base 3 in a first direction dr1. The connector 6 is movably connected to the slider 4 and is configured to connect adjacent display panels 2 among the plurality of display panels 2. The second adjustment mechanism 7 is disposed between the connector 6 and the slider 4 and is configured to adjust the position of the connector 6 relative to the slider 4 in a second direction dr2. The first direction dr1 intersects the mounting surface MS, and the second direction dr2 intersects the first direction dr1.
[0109] With reference to the description of directions in FIG. 1 , in some embodiments, the first direction dr1 is perpendicular to the mounting surface MS, and the second direction dr2 is perpendicular to the first direction dr1. The second direction dr1 may include at least one direction perpendicular to the first direction dr1. For example, for a vertically disposed mounting surface MS, the first direction dr1 and the second direction dr2 are perpendicular to each other and parallel to a horizontal plane.
[0110] The base 3 can be mounted on the mounting surface MS and has a portion that contacts and supports the mounting surface MS. The slider 4 is slidably arranged with the base 3. When the base 3 is fixed to the mounting surface MS, the slider 4 can be moved relative to the base 3 in a first direction dr1 via a first adjustment mechanism 5. Taking the first direction dr1 as an example, which is perpendicular to the mounting surface MS, the slider 4 can be moved relative to the base 3 in a direction perpendicular to the mounting surface MS via the first adjustment mechanism 5, thereby driving the connector 6 connected to the slider 4 to move in a direction perpendicular to the mounting surface MS, thereby adjusting the distance between the corners of the display panel 2 and the mounting surface MS, which helps to adjust the flatness of multiple display panels 2.
[0111] The connector 6 is movably connected to the slider 4. That is, the slider 4 is connected to the connector 6 and is movable relative to the connector 6. The connector 6 can be moved relative to the slider 4 in a second direction dr2 via a second adjustment mechanism 5. For example, in the case where the first direction dr1 is perpendicular to the mounting surface MS, and the second direction dr2 is perpendicular to the first direction dr1 and parallel to the horizontal plane, the connector 6 can be moved horizontally relative to the slider 4 via the second adjustment mechanism 7 to adapt to the installation position of the corner of the display panel 2, thereby improving the tolerance for display panel installation.
[0112] Through the structure of the above-mentioned connecting device and the adjustment function of the adjustment mechanism, the display panel connected by the connecting member can be adjusted in position in the first direction and the second direction that intersect each other, thereby improving the requirements of the display device including multiple display panels for the installation effect of the display panel.
[0113] For the case where the flatness of the mounting surface MS is poor, this embodiment can achieve higher planar mounting accuracy of the display panel by adjusting the position of the slider 4 in the first direction dr1, and can also achieve position adjustment in the second direction dr2. This eliminates the need for excessively high position accuracy requirements when the connecting device is connected to the display panel, thereby reducing the difficulty of installation, meeting the needs of embedded holes in situations where low accuracy requirements are required, and reducing the requirements for installation accuracy and professionalism.
[0114] Figure 7 is a schematic diagram of the structure of the base, the slider and the first adjustment mechanism in some embodiments of the connection device according to the present disclosure. Figure 8 is an external and cross-sectional schematic diagram of the position adjustment in the first direction in some embodiments of the connection device according to the present disclosure.
[0115] Referring to Figures 4, 6, and (b), (c), and (e) of Figure 7, in some embodiments, the first adjustment mechanism 5 includes: a screw 51, a worm gear 52, and a worm 53. The screw 51 is rotatably connected to the base 3 and is threadedly connected to the slider 4. The worm gear 52 is coaxially fixedly connected to the screw 51, so that the rotation of the worm gear 52 drives the screw 51 to rotate coaxially. The worm 53 is rotatably connected to the base 3 and meshes with the worm gear 52. It is configured to transmit rotation to the screw 51 via the worm gear 52, so that the rotation of the screw 51 drives the slider 4 to slide in the first direction dr1.
[0116] The spiral tooth profile 532 of the worm 53 can roll along the spiral tooth groove of the worm wheel 52 to form a continuous meshing action. When the worm 53 rotates, it can drive the worm wheel 52 to rotate. The worm wheel 52 can be fixedly connected to the screw 51 by means of a keyway or interference fit, or it can be an integral structure with the screw 51. The rotation of the worm wheel 52 also drives the screw 51 to rotate synchronously. The screw 51 has a threaded section 511, and the threaded section 511 is threadedly connected to the first threaded hole 43 provided on the slider 4. When the slider 4 is constrained and cannot rotate, when the screw 51 rotates, the slider 4 translates in the first direction dr1 or the opposite direction of the first direction dr1 under the action of the threaded section 511.
[0117] This first adjustment mechanism, which combines worm gear engagement with threaded engagement, can provide more refined, stepless position adjustment of the slider 4 in the first direction dr1 or in the direction opposite to the first direction dr1. In other embodiments, the first adjustment mechanism 5 can also adopt other structures, such as a gasket, a manual screw adjustment structure, etc.
[0118] Referring to Figures 6 and 7(b), in some embodiments, the worm 53 has an operating end 531 configured to receive external torque input to drive the worm 53 to rotate. In Figure 7(b), the operating end 531 can be configured to accommodate a hexagonal wrench for applying torque. When adjusting the connection device, the installer can advance or retract the connecting plate 6 in the first direction dr1 by tightening the hexagonal wrench connected to the operating end 531. This facilitates convenient adjustment of the display panel in the first direction.
[0119] In some embodiments, the axis of the worm 53 is vertically arranged, and the operating end 531 is located at the top of the worm 53. In this way, the installer can easily connect or disconnect the tool from the operating section 531 and perform the screwing operation at any time as needed, which helps to reduce the intensity and difficulty of the work.
[0120] With reference to Figures 4 and 6 , in some embodiments, the base 3 includes a support portion 31 and a receiving portion 32. The support portion 31 is configured to connect to the mounting surface MS. The receiving portion 32 is fixedly connected to or integral with the support portion 31 and has a receiving cavity 32a for accommodating at least a portion of the slider 4 and at least a portion of the first adjustment mechanism 5. The slider 4 slidably engages with the receiving cavity 32a.
[0121] The support portion 31 can be connected to the mounting surface MS through a snap-fit connection, bolt connection, or other means. The accommodating portion 32 and the support portion 31 can be two separate, connectable components, or a single, integrated component. The accommodating cavity 32a of the accommodating portion 32 can have at least one opening to allow the slider 4 to slide within the opening. Furthermore, the accommodating cavity 32 is capable of accommodating at least a portion of the slider 4 and at least a portion of the first adjustment mechanism 5, thereby providing support and protection for the slider 4 and the first adjustment mechanism 5.
[0122] 5 , in some embodiments, the support portion 31 has a support surface 311 capable of surface contact with the mounting surface MS. The support surface 311 is provided with a groove 312. The protruding end 51a of the screw 51, which extends away from the slider 4, penetrates the support portion 31 from the accommodating cavity 32a and emerges at the bottom of the groove 312. The screw 51 is constrained from longitudinal movement by a restraining member.
[0123] The support surface 311 can achieve reliable support through surface contact with the mounting surface MS, so that the display panel connected to the connecting device can be stably installed. The protruding end 51a of the screw 51 can pass through the opening 322a on the base 3, thereby penetrating the support portion 31 and being exposed at the bottom of the groove 312. This can facilitate the restraint effect of the restraining member in the groove 312 to prevent the screw 51 from moving in its length direction and affecting the position of the slider 4 in the first direction dr1. On the other hand, it can make the protruding end 51a and the restraining member located in the groove 312 to avoid interference with the mounting surface MS. Here, movement refers to the inappropriate axial movement of the screw 51 relative to the opening 322a on the base 3 in its own length direction (which is also the extension direction of the rotation axis of the screw 51). The restraining effect of the restraining member on the screw 51 in the groove 312 prevents the screw 51 from moving, thereby reducing the problems of reduced transmission accuracy and screw wear caused by the movement of the screw.
[0124] With reference to Figures 4 and 5 , in some embodiments, the restraining member includes a latch 54 inserted into the protruding end 51a of the screw 51. The groove 312 includes a first groove portion 312a. The bottom of the first groove portion 312a exposes the protruding end 51a, and the minimum distance between the groove wall of the first groove portion 312a and the centerline of the screw 51 is greater than or equal to 1 / 2 the length of the latch 54.
[0125] The protruding end 51a is exposed at the bottom of the first groove 312a, and the latch 54 is inserted into the pin hole in the protruding end 51a. The latch 54 can be formed into a cylindrical structure and has an interference fit with the pin hole. By ensuring that the minimum distance between the groove wall of the first groove 312a and the centerline of the screw 51 is greater than or equal to 1 / 2 the length of the latch 54, the latch 54 can rotate within the first groove 312a when 1 / 2 the length is located in the center of the protruding end 51a, thereby not restricting the normal rotation of the screw 51.
[0126] Referring to Figure 5 , in some embodiments, the groove 312 further includes a second groove portion 312b. The second groove portion 312b connects the side of the support portion 31 and the first groove portion 312a. The minimum distance between the groove wall of the first groove portion 312a and the centerline of the screw 51 is less than the length of the latch pin 54.
[0127] By ensuring that the minimum distance between the wall of the first groove portion 312a and the centerline of the screw 51 is less than the length of the latch pin 54, the wall of the first groove portion 312a can block the latch pin 54, reducing the risk of failure of the first adjustment mechanism 5 due to the latch pin 54 falling out of the pin hole. To facilitate installation and removal of the latch pin 54, a second groove portion 312b is provided, connecting the side of the support portion 31 and the first groove portion 312a. This allows the latch pin 54 to enter the first groove portion 312a through the second groove portion 312b and connect with the extension end 51a, or to disengage from the extension end 51a and exit the support portion 31 through the second groove portion 312b.
[0128] In FIG5 , the second groove portion 312 b may include straight grooves located on both sides of the first groove portion 312 a , and the width of the straight grooves is smaller than the diameter of the first groove portion 312 a .
[0129] Referring to FIG7 (a), in some embodiments, the accommodating portion 32 includes: a bottom plate 321, a first side plate 322, and a second side plate 323 and a third side plate 324 arranged opposite to each other. The worm 53 is rotatably connected to the bottom plate 321, and the slider 4 is slidable on the bottom plate 321. The first side plate 322 is fixedly connected to the bottom plate 321 or is an integral structure, and the screw 51 is rotatably connected to the first side plate 322. The second side plate 323 and the third side plate 324 arranged opposite to each other are fixedly connected to the bottom plate 321 and the first side plate 322 or are an integral structure, and the slider 4 is slidably engaged with the second side plate 323 and the third side plate 324.
[0130] The bottom plate 321 can support the slider 4 by surface contact, so that the slider 4 slides on the bottom plate 321. The bottom plate 321 can be provided with a bottom hole 321a to allow the worm 53 to be inserted at the end 533 of the spiral tooth profile 532 on the side away from the operating end 531. The first side plate 322 is fixedly connected to the support portion 31 or is an integral structure. The first side plate 322 can be provided with an opening 322a to allow the protruding end 51a of the screw 51 to pass through. The second side plate 323 and the third side plate 324 can each have a sliding surface parallel to each other, so that the slider 4 can slide within the channel formed by the second side plate 323 and the third side plate 324.
[0131] Referring to Figures 4, 6, and 7(f), in some embodiments, the base 3 further includes a cover plate 33. The cover plate 33 is detachably connected to the accommodating portion 32 and, together with the accommodating cavity 32a, encloses a sliding passage for the slider 4. The worm 53 has an operating end 531 that passes through the cover plate 33 and is exposed therefrom.
[0132] The cover plate 33 can be secured to the tops of the first side plate 322, the second side plate 323, and the third side plate 324 by engaging the screw holes 332 therein with the screws 34. To disassemble or repair the first adjustment mechanism 5, the cover plate 33 can be removed, exposing the worm 53, the worm wheel 52, and the screw 51 within the accommodating cavity 32a. The cover plate 33 conceals the first adjustment mechanism 5, preventing foreign matter from entering the accommodating cavity 32a and potentially affecting its operation. Furthermore, the cover plate 33, together with the base plate 321, the second side plate 323, and the third side plate 324, forms the walls of the sliding channel of the slider 4.
[0133] Referring to (a) and (b) of Figure 7, the worm 53 can be set in a stepped form, wherein the end 533 of the worm 53 on the side of the spiral tooth profile 532 away from the operating end 531 can be inserted into the bottom hole 321a set on the base 3, and the operating end 531 is inserted into and passes through the cover plate through hole 333 on the cover plate 33, so that the worm 53 can achieve stable rotation support through the cover plate through hole 333 and the bottom hole 321a.
[0134] In order to control the adjustment range of the slider 4 relative to the base 3 in the first direction dr1 , in some embodiments, a limiting structure is provided between the cover 33 and the slider 4 to limit the sliding stroke of the slider 4 relative to the base 3 .
[0135] 6 , FIG7 (d), (f) and FIG8 (a)-(d), in some embodiments, the restraining structure includes: a recessed portion 41 and a raised portion 331. The recessed portion 41 is provided on the surface of the slider 4 adjacent to the cover plate 33. The raised portion 331 is provided on the surface of the cover plate 33 adjacent to the slider 4, embedded in the recessed portion 41, and movable within the recessed portion 41.
[0136] By moving the raised portion 331 on the cover 33 within the recessed portion 41, the position adjustment requirement of the slider 4 relative to the base 3 in the first direction dr1 is met, and by the limiting effect of the edge of the recessed portion 41 on the raised portion 331, the adjustment range of the slider 4 relative to the base 3 in the first direction dr1 is limited (for example, the adjustment stroke is limited to 4, 5 or 6 mm).
[0137] In (d) and (f) of Figure 7, the raised portion 331 can be raised relative to the surface of the cover plate 33 on the side adjacent to the slider 4, and its shape can be rectangular or other shapes; the recessed portion 41 is recessed relative to the surface of the slider 4 on the side adjacent to the cover plate 33, and the recessed depth is not less than the raised height of the raised portion 331, and its shape can be a shape that matches the raised portion 331, such as a rectangle.
[0138] Figure 8(c) is a schematic diagram of the AA section in Figure 8(a), and Figure 8(d) is a schematic diagram of the BB section in Figure 8(b). Compared to Figure 8(a), Figure 8(b) shows that the left connector 6 and slider 4 are further away from the base 3 in the first direction dr1, which is equivalent to the connector 6 being adjusted to a position further away from the mounting surface MS. As can be seen from Figures 8(c) and (d), in the AA section, the screw 52 penetrates the slider 4 to a greater depth, and there is essentially no gap between the cover plate 33 and the slider 4 in the first direction dr1. In contrast, in the BB section, the screw 52 penetrates the slider 4 to a shallower depth, and there is a gap d between the cover plate 33 and the slider 4 in the first direction dr2.
[0139] 3-7 , in some embodiments, the connecting member 6 has a first guide hole 61. The second adjustment mechanism 7 includes a first locking bolt 71 and a raised ring 42 of the slider 4. The raised ring 42 is embedded in the first guide hole 61 and is slidable in the second direction dr2. The first locking bolt 71 passes through the first guide hole 61 and is threadedly engaged with the raised ring 42, thereby locking the relative position of the connecting member 6 and the slider 4 in the second direction dr2.
[0140] In Figures 3 and 4, it can be seen that the first guide hole 61 can be set as a countersunk hole so that the end of the first locking bolt 71 is lower than the surface of the connecting member 6 on the side adjacent to the display panel 2, thereby reducing the risk of interference between the display panel 2 and the first locking bolt 71.
[0141] In Figures 4 and 7(d) and (e), it can be seen that the collar 42 protrudes from the surface of the slider 4 adjacent to the connector 6 and has a threaded hole that can be threadedly engaged with the first locking bolt 71. The first guide hole 61 can be an oblong hole that can achieve a clearance fit with the collar 52. This structure enables stepless adjustment of the position in the second direction dr2.
[0142] To achieve effective guidance and more reliable locking, in some embodiments, the connector 6 has two first guide holes 61 spaced apart in the third direction dr3. The second adjustment mechanism 7 includes two first locking bolts 71 corresponding one-to-one with the two first guide holes 61. The first adjustment mechanism 5 includes a screw 51 rotatably connected to the base 3 and threadedly connected to the slider 4. The screw 51 is positioned between the two first locking bolts 71 in the third direction dr3, which intersects both the first direction dr1 and the second direction dr2. Positioning the screw 51 between the two first locking bolts 71 ensures a more balanced force on the slider in the third direction dr3.
[0143] Specifically, the first direction dr1 may be perpendicular to the mounting surface MS, the second direction dr2 may be perpendicular to the first direction dr1 , and the third direction dr3 may be perpendicular to both the first direction dr1 and the second direction dr2 .
[0144] Furthermore, referring to FIG3 , the connector 6 may be plate-shaped and may be provided with a plurality of connection holes 63 for connecting multiple display panels 2 that are spliced at the location of the connector 6 . Referring to FIG4 and FIG7 (d) and (e), the slider 4 includes a sliding portion that can enter the accommodating cavity 321a and a supporting portion located on the side of the sliding portion adjacent to the connector 6 . In the first direction dr1 , the supporting portion has a larger cross-sectional dimension than the sliding portion to provide more stable contact and support with the connector 6 . Accordingly, the slider 4 may have a T-shaped longitudinal cross-section.
[0145] The second adjustment mechanism 7 is not limited to the structure shown in the previous embodiment, and may also adopt other forms.
[0146] Figure 9 is a schematic diagram of the exploded structure of other embodiments of the connecting device according to the present disclosure. Figure 10 is a schematic diagram of the structure of the connecting member according to other embodiments of the connecting device according to the present disclosure from different perspectives. Figure 11 is a schematic diagram of the structure of the slider according to other embodiments of the connecting device according to the present disclosure from different perspectives. Figure 12 is a schematic diagram of the exterior and cross-section of other embodiments of the connecting device according to the present disclosure adjusting the position in the first direction.
[0147] Referring to Figures 9-12, in some embodiments, the connecting member 6 includes a guide rail 62 extending along the second direction dr2. The second adjustment mechanism 7 includes a slide groove 72 and a second locking bolt 73. The slide groove 72 is disposed on a side of the slider 4 adjacent to the connecting member 6 and slidably engages with the guide rail 62. The second locking bolt 73 passes through the wall of the slide groove 72 and is configured to lock the guide rail 62 by abutting against it.
[0148] Compared with the embodiment shown in FIG4 , the slider 4 and the connecting plate 6 in FIG9 are structurally different. For other structures, reference may be made to the description of the embodiment shown in FIG4 , which will not be repeated here.
[0149] In Figures 10(b)-10(d), the guide rail 62 is located on the surface of the connector 6 adjacent to the slider 4 and may be raised relative to this surface. In Figures 9 and 11(b) and 11(d), a chute 72 may be configured to accommodate a portion of the guide rail 62 and allow the guide rail 62 to slide relative to the chute 72. The chute 72 may be configured with a narrow notch to prevent the guide rail 62 from slipping out of the chute 72. Furthermore, the chute wall of the chute 72 is provided with a second threaded hole 721 through which a second locking bolt 73 can pass. This allows the guide rail 62 to slide or lock by loosening or tightening the second locking bolt 73.
[0150] Figure 11(b) is a schematic diagram of the CC section in Figure 11(a). In Figure 11(b), it can be seen that the same section (CC section) passes through the first threaded hole 43, the recessed portion 41, the sliding groove 72, and the second threaded hole 721 on the slider 4. This facilitates the stability of the slider 4 in various states, including fixed, positioned, and sliding.
[0151] Referring to Figures 10(b) and 10(d) and Figures 12(c) and 12(d), in some embodiments, the end of the second locking bolt 73 that abuts the guide rail 62 is tapered. A locking groove 621 is provided on the surface of the guide rail 62 adjacent to the second locking bolt 73. The locking groove 621 extends along the second direction dr2 and has a V-shaped cross-section in the second direction dr2 that fits snugly within the tapered shape. This mating structure facilitates effective locking at all positions along the second direction dr2.
[0152] Figure 12(c) is a schematic diagram of the DD section in Figure 12(a), and Figure 12(d) is a schematic diagram of the EE section in Figure 12(b). Compared to Figure 12(a), Figure 12(b) shows that the left connector 6 and slider 4 are further away from the base 3 in the first direction dr1, which is equivalent to the connector 6 being adjusted to a position further away from the mounting surface MS. As can be seen from Figures 12(c) and (d), in the DD section, the screw 52 penetrates the slider 4 to a greater depth, and there is essentially no gap between the cover plate 33 and the slider 4 in the first direction dr1. In contrast, in the EE section, the screw 52 penetrates the slider 4 to a shallower depth, and there is a gap d between the cover plate 33 and the slider 4 in the first direction dr2.
[0153] Based on the above embodiments, the connecting device CD can also implement position adjustment in the third direction dr3, thereby providing the display panel 2 with a degree of adjustment freedom in the third direction dr3. Referring to Figures 3-5 and 9, in some embodiments, the connecting device CD further includes a third adjustment mechanism 8. The third adjustment mechanism 8 is disposed on the base 3 and is configured to adjust the position of the base 3 relative to the mounting surface MS in the third direction dr3. The third direction dr3 intersects both the first direction dr1 and the second direction dr2.
[0154] Optionally, the first direction dr1 is perpendicular to the mounting surface MS, the second direction dr2 is perpendicular to the first direction dr1 , and the third direction dr3 is perpendicular to both the first direction dr1 and the second direction dr2 .
[0155] Referring to Figure 4 , in some embodiments, the third adjustment mechanism 8 includes a second guide hole 81 and a third locking bolt 82 . The second guide hole 81 is formed in the base 3 . The third locking bolt 82 passes through the second guide hole 81 and is threadedly engaged with the mounting surface MS. The third locking bolt 82 is slidable within the second guide hole 81 along the third direction dr3 and is capable of locking the position of the base 3 relative to the mounting surface MS in the second direction dr2 . This adjustment structure enables stepless adjustment of the position in the third direction dr3 , and is simple in structure and easy to implement and adjust.
[0156] In some embodiments, the base 3 includes a support portion 31 and a receiving portion 32. The support portion 31 is configured to connect to the mounting surface MS. The receiving portion 32 is fixedly connected to or integral with the support portion 31 and includes a receiving cavity 32a for accommodating at least a portion of the slider 4 and at least a portion of the first adjustment mechanism 5. The slider 4 slidably engages with the receiving cavity 32a. Accordingly, the support portion 31 may define two second guide holes 81 spaced apart in the third direction dr3. The third adjustment mechanism 8 may include two third locking bolts 82 corresponding to the two second guide holes 81. The receiving portion 32 is located between the two second guide holes 81 in the third direction dr3. These two third locking bolts 82 not only enable position adjustment of the base 3 in the third direction dr3 but also provide stable support for the receiving cavity 32a connected to the slider 4.
