Detailed Implementation

[0077] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0078] In the description of the present application, unless explicitly defined and limited, the terms "connected", "fixed" should be understood broadly, for example, can be fixedly connected, can be detachably connected or integrated; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0079] In the present application, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0080] Splicing screen refers to a larger display screen formed by splicing and combining two or more display screen bodies. The splicing screen can also be called a splicing display device or a splicing interactive panel. In the field of display devices, with the development of market demand, two-splicing products formed by splicing two screen bodies and multi-splicing products formed by splicing more than three screen bodies are increasingly widely used, for example: the splicing screen can be applied to shopping malls, exhibitions and other places to display product information, advertising information, etc.; can be applied to monitoring centers to display multiple monitoring pictures; can be applied to conference rooms or classrooms to display conference content or teaching content and provide touch interaction function. The splicing intelligent blackboard applied to classrooms, the splicing conference panel applied to conference rooms and the splicing interactive panel applied to exhibition halls are all splicing screens.

[0081] In the related art, when installing the spliced screen, each independent screen body is generally installed to the installation surface, and the installation surface generally refers to the wall surface of the wall. The installation surface can also be provided by the front side surface of the plurality of vertical supports in the steel frame structure. However, during the installation of the screen bodies of the spliced screen, the relative positions between the screen bodies may not meet the requirements due to various reasons, and the following problems may occur: the spliced gap between the adjacent screen bodies is large, the width of the spliced gap between the adjacent screen bodies is not uniform, the up-down alignment between the adjacent screen bodies is not neat, and the front-back difference between the adjacent screen bodies is not flat.

[0082] The present inventors have developed various components for installing the screen bodies 80 to the installation surface 92 to solve the problem of poor alignment between the adjacent screen bodies 80 after the screen bodies 80 are installed to the installation surface 92. However, during the development process, the inventors found the following problems:

[0083] First, during installation, the support member is fixed to the installation surface 92, and then the screen body 80 is hung on the support member to support the screen body 80. However, when the support member is installed to the installation surface 92, the actual installation position of the support member may be higher or lower than the set installation position due to installation errors of the installer, which may cause the overall installation position of the screen body 80 to be inaccurate. The inaccurate up-down position may be that the overall position of one of the screen bodies 80 is relatively low relative to the other screen body 80, or that one of the screen bodies 80 is in an inclined state, for example, Figure 22 which illustrates the state in which the right screen body 80 is inclined to the right. The up-down positions of the adjacent screen bodies 80 are not aligned, which affects the overall appearance, as shown in Figure 22 If one of the screen bodies 80 is inclined, a spliced gap may occur between the adjacent screen bodies 80, and the width of the spliced gap at different positions is inconsistent. For the spliced screen with a writing touch function, when the writing track needs to cover two adjacent screen bodies 80, the spliced gap will cause the writing track to be interrupted, affecting the writing experience.

[0084] Second, due to the unevenness of the wall surface, the display surfaces 82 of the adjacent screen bodies 80 are not in the same plane, which may cause a front-back difference between the adjacent screen bodies 80, so that the display surface 82 of one of the screen bodies 80 is in front of the display surface 82 of the other screen body 80 at the spliced position. For example, Figure 23 which illustrates that one of the two screen bodies 80 is inclined backward relative to the other screen body 80. The front-back difference between the screen bodies 80 not only affects the appearance of the spliced screen and the overall integrity, but also causes writing lag between the screen bodies 80 when the writing track needs to cover two adjacent screen bodies 80, affecting the writing experience.

[0085] Third, the spliced screen is directly installed to the wall surface, and the left-right position of the spliced screen cannot be adjusted after installation.

[0086] Fourthly, the weight of the single screen body 80 in the spliced screen is relatively heavy. Taking the spliced smart blackboard or the spliced interactive panel as an example, the weight of a single display screen is almost 10 kg. During installation and construction, the first screen body 80 is generally installed first, and then the second screen body 80 is installed. When the second screen body 80 is installed, the second screen body 80 needs to be close to the first screen body 80, and the side edges of the two screen bodies 80 are as close as possible. However, due to the relatively heavy weight of the single screen body 80, it is difficult to effectively control the position of the second screen body 80 by relying on the installation personnel to close the second screen body 80 to the first screen body 80, which may cause a splicing gap between the two screen bodies 80, and it is also easy to cause the splicing gap to be uneven. For example, Fig. 21 schematically shows the case of a splicing gap between the screen bodies 80 when the two screen bodies 80 are spliced. The splicing gap between the adjacent screen bodies 80 and the uneven splicing gap not only cause black lines in the display picture of the spliced screen, affecting the display effect, but also affect the appearance and integrity of the spliced screen, and also affect the writing and touch experience.

[0087] Of course, in addition to the above-mentioned installation problems encountered in the research and development process, other factors may also cause the left-right, up-down, and front-back positions of the screen bodies 80 to be inaccurate during the installation of the spliced screen, and the positions are difficult to adjust, thereby affecting the integrity and use effect of the spliced screen.

[0088] The installation assembly and the spliced screen of the present application can adjust the positions of the screen bodies 80 in the up-down, left-right, and front-back directions during the installation process, thereby improving the position alignment degree between the adjacent screen bodies 80, and improving the integrity and use effect between the adjacent screen bodies 80. It can be understood that the installation assembly of the present application is used to solve one or more installation problems encountered by the inventors in the research and development process.

[0089] Please refer to Figures 1 to 23 The present application provides an installation assembly and a spliced screen.

[0090] The spliced screen comprises a plurality of screen bodies 80 and a mounting assembly. At least one screen body 80 of each two adjacent screen bodies 80 is provided with the mounting assembly on the rear side. The mounting assembly comprises a first mounting assembly, which is used for mounting the screen body 80 to the mounting surface 92. The first mounting assembly is provided with three mounting members, which can be hung on the wall surface or other mounting surface 92. The relative position between the mounting members can be adjusted to adjust the up-down, left-right and front-rear positions of the screen body 80, so that the splicing gap between the adjacent screen bodies 80 is smaller, the up-down or front-rear alignment between the adjacent screen bodies 80 is more accurate, and the difference is reduced, thereby improving the mounting effect of the spliced screen, improving the appearance and integrity of the spliced screen, and improving the use experience of the spliced screen. The spliced screen has higher flatness and smaller splicing gap, the display effect of the spliced screen meets higher requirements, and the writing experience is better. The first adjusting member 14 provides a manual operation position for the operator, which facilitates the up-down position adjustment of a certain part or the whole of the screen body 80.

[0091] It should be noted that, in order to facilitate the illustration and description of the relative positions between the components, in the drawings, the left-right direction of the spliced screen and each component is illustrated by the x direction, the up-down direction of the spliced screen and each component is illustrated by the y direction, and the front-rear direction of the spliced screen and each component is illustrated by the z direction. When the spliced screen is applied, the front side of the spliced screen is the side facing the user, and the rear side is the side facing the mounting surface 92. In order to facilitate the description, the left-right direction and the up-down direction of the spliced screen and each component refer to the left-right direction and the up-down direction of the user when the spliced screen is applied and the display surface 82 of the spliced screen faces the user. In other cases, the left-right direction and the up-down direction of the spliced screen and each component can also be other directions. It should be further noted that, in this application, adjusting the up-down position of a component means that the position of the component can only be adjusted upward, or the position of the component can only be adjusted downward, or the position of the component can be adjusted upward and downward. In this application, adjusting the front-rear position of a component means that the position of the component can only be adjusted forward, or the position of the component can only be adjusted backward, or the position of the component can be adjusted forward and backward. It can be understood that, for the screen body 80 provided with the first wall hanging assembly 10 on the rear side, the screen body 80 can drive the first hanging member to move left or right when the screen body 80 moves left or right. For the screen body 80 provided with the second wall hanging assembly 20 on the rear side, the second hanging member can drive the screen body 80 to move when the second hanging member moves upward, downward, forward or backward.

[0092] Please continue to refer to Figures 1 to 23 , the mounting assembly and the spliced screen of the present application will be described below.

[0093] The mounting assembly is used for mounting the screen body 80 to the mounting surface 92, and is also used for adjusting the position of the screen body 80 during the mounting of the screen body 80. The mounting surface 92 can refer to a wall surface (such as a wall surface of a building, or a glass curtain wall, etc.), and the mounting surface 92 can also be a mounting surface 92 provided by a structure such as a steel frame (for example, a large steel frame used to provide a mounting surface 92 for a large screen of a spliced screen in a concert venue).

[0094] The first wall hanging assembly 10 is used for adjusting at least the left-right position and the up-down position of the screen body 80 during the mounting of the screen body 80 to the mounting surface 92. The first wall hanging assembly 10 comprises a first mounting member 11, a second mounting member 12, and a third mounting member 13. The first mounting member 11 is used for connecting with the mounting surface 92 and supporting the second mounting member 12. The second mounting member 12 is movably connected with the first mounting member 11 and can move relative to the first mounting member 11 in the left-right direction. The third mounting member 13 is used for connecting with the screen body 80. The third mounting member 13 is movably connected with the second mounting member 12 through a connecting structure 15, and can move relative to the second mounting member 12 in the up-down direction. The third mounting member 13 can move relative to the second mounting member 12 in the front-rear direction, and / or the second mounting member 12 can move relative to the first mounting member 11 in the front-rear direction. A first adjusting member 14 is arranged between the third mounting member 13 and the second mounting member 12, and is used for adjusting the up-down position of the third mounting member 13 relative to the second mounting member 12.

[0095] Referring to the drawings Figure 1 , Figure 7 The mounting assembly comprises the first wall hanging assembly 10, and the first wall hanging assembly 10 comprises the first mounting member 11, the second mounting member 12, and the third mounting member 13. The first mounting member 11 is used for connecting with the mounting surface 92 and supporting the second mounting member 12. The second mounting member 12 is movably connected with the first mounting member 11 and can move relative to the first mounting member 11 in the left-right direction. The third mounting member 13 is used for connecting with the screen body 80. The third mounting member 13 is movably connected with the second mounting member 12 through the connecting structure 15, and can move relative to the second mounting member 12 in the up-down direction. The third mounting member 13 can move relative to the second mounting member 12 in the front-rear direction, and / or the second mounting member 12 can move relative to the first mounting member 11 in the front-rear direction. A first adjusting member 14 is arranged between the third mounting member 13 and the second mounting member 12, and is used for adjusting the up-down position of the third mounting member 13 relative to the second mounting member 12.

[0096] The second mounting member 12 is arranged at least partially on the upper side of the first mounting member 11, so that the second mounting member 12 supports the first mounting member 11 upward, i.e., the second mounting member 12 is hung on the first mounting member 11. The third mounting member 13 is arranged at least partially on the upper side of the second mounting member 12, so that the third mounting member 13 supports the second mounting member 12 upward, i.e., the third mounting member 13 is hung on the second mounting member 12. During the mounting of the screen body 80, the first mounting member 11 is first fixed to the mounting surface 92, the third mounting member 13 is mounted to the rear side of the screen body 80, the second mounting member 12 is arranged between the first mounting member 11 and the second mounting member 12, and the first wall hanging assembly 10 is mounted. After the mounting of the first wall hanging assembly 10, the screen body 80 is preliminarily hung on the mounting surface 92. At this time, the first mounting member 11 supports the second mounting member 12, the second mounting member 12 supports the third mounting member 13, and the screen body 80 can be hung on the vertical mounting surface 92 through the first hanging assembly.

[0097] The second mounting member 12 is configured to be movable relative to the first mounting member 11 in the left-right direction under an external force, so that the left-right position of the screen body 80 relative to the wall can be adjusted during installation of the screen body 80. The third mounting member 13 is configured to be movable relative to the second mounting member 12 in the up-down direction under an external force, so that the up-down position of the screen body 80 relative to the wall can be adjusted during installation. In addition, the third mounting member 13 is configured to be movable relative to the second mounting member 12 in the front-rear direction under an external force, or the second mounting member 12 is configured to be movable relative to the first mounting member 11 in the front-rear direction under an external force, so that the front-rear position of the screen body 80 relative to the wall can be adjusted during installation.

[0098] In the present application, the left-right, front-rear, and up-down positions of the screen body 80 can be adjusted by moving the screen body 80 relative to the first mounting member 11, so that the left-right position joint between adjacent screen bodies 80 is reduced, and the front-rear and / or up-down step difference between screen bodies 80 is reduced during installation. The installation effect of the spliced screen is better.

[0099] In addition, the first wall-hanging assembly 10 is beneficial to the up-down or front-rear position adjustment of the screen body 80 during installation. The first adjusting member 14 is arranged between the third mounting member 13 and the second mounting member 12, and is used to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12. In this way, when the screen body 80 is hung on the installation surface 92 by the first wall-hanging assembly 10, the operator can manually or automatically operate the first adjusting member 14 to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12 by adjusting the first adjusting member 14, so as to adjust the up-down position of the screen body 80 relative to the installation surface 92. Through the arrangement of the first adjusting member 14, the position of the screen body 80 can be adjusted by operating the first adjusting member 14, and the second mounting member 12 can still provide upward supporting force to the third mounting member 13 and the screen body 80, so that the screen body 80 is supported at the current position after the up-down position is adjusted.

[0100] During installation of the screen body 80, before or after adjustment of the left-right position of the screen body 80, if the installer considers that the up-down position of the screen body 80 is not appropriate, the up-down position of the screen body 80 can be fine-adjusted by operating the first adjusting member 14, so as to try to make the up-down alignment degree between adjacent screen bodies 80 meet the requirements, so as to reduce the up-down step difference between adjacent screen bodies 80. Exemplarily, the up-down alignment degree between adjacent screen bodies 80 not meeting the requirements means that the upper edges of the two screen bodies 80 are not on a straight line, or Figure 22The lower sides of the two screen bodies 80 are not in a straight line; the up-and-down alignment of adjacent screen bodies 80 meets the requirement, which means that the two screen bodies 80 have no up-and-down position difference or the up-and-down position difference is within the error range. Exemplarily, the front-and-back alignment of adjacent screen bodies 80 does not meet the requirement, which means that the display surfaces 82 of the two screen bodies 80 are not in the same plane, and the front-and-back alignment of adjacent screen bodies 80 does not meet the requirement, which means that the display surfaces 82 of the two screen bodies 80 are not in the same plane. Figure 23 The display surfaces 82 of the two screen bodies 80 are not in the same plane; the front-and-back alignment of adjacent screen bodies 80 meets the requirement, which means that the difference between the display surfaces 82 of the two screen bodies 80 is within the error range.

[0101] In the first wall-hanging assembly 10, the second mounting member 12 is reused, and the second mounting member 12 is used in cooperation with the first mounting member 11 to reduce the difficulty of adjusting the left-and-right position of the screen body 80, and the second mounting member 12 is used in cooperation with the third mounting member 13 to adjust the position of the screen body 80 in another direction (up-and-down position), which is beneficial to reducing the number of parts used in the mounting process of the screen body 80, simplifying the mounting process of the screen body 80, making the structure of the mounting assembly simpler, and making the mounting of each screen body 80 in the spliced screen simpler.

[0102] Optionally, the third mounting member 13 is connected to the second mounting member 12 through the connecting structure 15, and the third mounting member 13 can move relative to the second mounting member 12 in the up-and-down direction under the action of an external force; the connecting structure 15 is used to limit the movement of the third mounting member 13 relative to the second mounting member 12 in the left-and-right direction. Compared with the scheme in which the left-and-right position of the third mounting member 13 relative to the second mounting member 12 is not limited and the second mounting member 12 only provides upward supporting force to the third mounting member 13, after the connecting structure 15 is arranged in the embodiment, the connecting structure 15 can transmit the left-and-right movement driving force, and when the screen body 80 moves left and right to drive the third mounting member 13 to move left and right, the connecting structure 15 drives the second mounting member 12 to move left and right synchronously, thereby adjusting the left-and-right position of the screen body 80 and adjusting the spliced gap. The connecting structure 15 also has the effect of stably hanging the third mounting member 13 on the second mounting member 12 and preventing the third mounting member 13 from slipping off and falling, thereby stably hanging the screen body 80. When the connecting structure 15 drives the second mounting member 12 to move left and right, at least a part of the connecting structure 15 is located between the second mounting member 12 and the first mounting member 11 and can rotate under the action of friction, thereby reducing the resistance of the screen body 80 and the second mounting member 12 to move left and right, or a separate rolling structure 16 is arranged between the second mounting member 12 and the first mounting member 11, and when the connecting structure 15 drives the second mounting member 12 to move left and right, the rolling structure 16 rotates, thereby reducing the resistance of the screen body 80 to move left and right.

[0103] Referring to Figure 3 , Figures 8 to 12The first mounting member 11 comprises a first fixing portion 111 and a first supporting portion 112 connected with each other. The first fixing portion 111 is configured to be connected with the mounting surface 92. Optionally, the first supporting portion 112 is at least partially located in front of the first fixing portion 111, so as to facilitate reserving a gap between the first supporting portion 112 and the mounting surface 92, and facilitate hanging the second mounting member 12 on the first supporting portion 112. The third mounting member 13 comprises a third fixing portion 1303 and a third supporting portion 1304 connected with each other. The third fixing portion 1303 is configured to be connected with the screen body 80. Optionally, the third supporting portion 1304 is at least partially located in front of the third fixing portion 1303, so as to reserve a gap between the third supporting portion 1304 and the back surface of the screen body 80, and facilitate accommodating some other components to be locked. The second mounting member 12 is at least partially arranged between the first supporting portion 112 and the third supporting portion 1304. The first supporting portion 112 supports the second mounting member 12, the second mounting member 12 supports the third supporting portion 1304, and the third supporting portion 1304 is movably connected with the second mounting member 12 through the connecting structure 15.

[0104] It can be understood that the third mounting member 13 is provided with different parts, for example, two plate portions, so as to respectively provide the function of being connected with the screen body 80 and the function of being supported by the second mounting member 12 and being configured to arrange the first adjusting member 14, so that the structure of the third mounting member 13 is more reliable and convenient to operate. In other embodiments, the third mounting member 13 can not be divided into the fixing portion and the supporting portion, but only one thick plate member above the second mounting member 12 is provided, so as to provide the function of cooperating with the second mounting member 12 and the function of cooperating with the screen body 80. The following embodiments are all taken as examples of the third mounting member 13 comprising the third fixing portion 1303 and the third supporting portion 1304, and the mounting assembly is further described.

[0105] With reference to Figures 10 to 12 , Figure 14 , Figure 16 , Figure 18The second mounting member 12 includes a second front side plate 121 and a second rear side plate 123 arranged oppositely, and further includes a second top plate 122. Two ends of the second top plate 122 are connected with the second front side plate 121 and the second rear side plate 123 respectively, and the second front side plate 121, the second top plate 122 and the second rear side plate 123 enclose a first recess 1201. The lower side of the second mounting member 12 has a bottom notch in communication with the first recess 1201. The first support part 112 can be inserted into the first recess 1201 from the notch at the bottom of the second mounting member 12, and the first support part 112 supports the second top plate 122, and the second front side plate 121 and the second rear side plate 123 are respectively located on the two sides of the first support part 112. The second mounting member 12 can move relative to the first support part 112 in the left-right direction under the action of an external force. The second mounting member 12 is in an upper-lower plug-in fit with the first mounting member 11, and is in a front-rear limiting fit with the first mounting member 11. In this way, in the case that the screen body 80 and the second mounting member 12 slide relative to the fixed first mounting member 11 in the left-right direction, the second mounting member 12 can be stably hung on the first mounting member 11, and the second mounting member 12 is not easy to slide off the first mounting member 11 and fall off, thereby ensuring the stability of the hanging of the screen body 80. Through the upper-lower plug-in fit between the second mounting member 12 and the first support part 112, not only can the two slide relative to each other in the left-right direction to adjust the left-right position of the screen body 80, but also the first support part 112 can play multiple functions of sliding guide, front-rear support and front-rear limiting of the second mounting member 12.

[0106] Optionally, the first support part 112 of the first mounting member 11 can limit the forward displacement and the rearward displacement of the second mounting member 12, thereby improving the hanging stability and avoiding the screen body 80 from being turned over in the direction away from the screen body 80 during the installation process. In other embodiments, the second mounting member 12 can also be arranged only on the upper side of the first support part 112 of the first mounting member 11, that is, the first support part 112 does not have the front-rear limiting function for the second mounting member 12.

[0107] In an embodiment, the plug-in fit between the first support part 112 and the second mounting member 12 is realized in the following manner. Referring to Figures 10 to 12 、 Figure 14 、 Figure 16 、 Figure 18The second mounting member 12 includes a second front side plate 121, a second top plate 122, and a second rear side plate 123. The two ends of the second top plate 122 are connected with the second front side plate 121 and the second rear side plate 123 respectively. The second front side plate 121, the second top plate 122, and the second rear side plate 123 enclose a first recess 1201. The lower side of the second mounting member 12 has a bottom notch in communication with the first recess 1201. The cross section of the second mounting member 12 is similar to an inverted "U" shape. The first support part 112 is inserted into the first recess 1201 from bottom to top through the bottom notch. The second front side plate 121 and the second rear side plate 123 are respectively located on the two sides of the first support part 112.

[0108] In the embodiment, the first mounting member 11 can be inserted into the first recess 1201 of the second mounting member 12 to support the second mounting member 12 and limit the front and back positions of the two members. The left and right ends of the first recess 1201 can form end notches for the first support part 112 to pass through. The length of the first mounting member 11 in the left-right direction can be configured to be relatively long. The first mounting member 11 can be used as a guide to facilitate the adjustment of the left-right position of the second mounting member 12 on the first mounting member 11. In the embodiment, the second mounting member 12 has an inverted "U" shape. When installing, the second mounting member 12 only needs to be buckled on the first support part 112. Therefore, the installation is convenient and fast, and the alignment difficulty is small.

[0109] In the case where the second mounting member 12 is provided with the first recess 1201, the top surface of the first support part 112 can not have a recess. The first support part 112 can have a cross section design with higher structural strength. The top surface of the first support part 112 can have more area for supporting the second mounting member 12, thereby ensuring the reliable support of the first support part 112 on the second mounting member 12 and the screen body 80. The first support part 112 has good force bearing effect and strong anti-deformation ability.

[0110] Referring to Figures 10 to 12 , Figure 14 , Figure 16 , Figure 18The third support portion 1304 includes a third front side plate 131 and a third rear side plate 133 disposed opposite to each other, and also includes a third top plate 132. The two sides of the third top plate 132 are respectively connected to the third front side plate 131 and the third rear side plate 133. The third front side plate 131, the third top plate 132, and the third rear side plate 133 enclose each other to form a second groove 1301. The lower side of the third support portion 1304 has a bottom slot communicating with the first groove 1201. The second mounting member 12 is inserted into the second groove 1301. The third front side plate 131, the second front side plate 121, the second rear side plate 123, and the third rear side plate 133 are distributed from front to back. The second top plate 122 is located between the first support portion 112 and the third top plate 132, and the second top plate 122 supports the third top plate 132. The second mounting piece 12 is inserted into the second groove 1301, which helps to strengthen the front and rear limit of the third mounting piece 13, improve the stability of the hanging, and prevent the screen body 80 from tipping over in the direction away from the screen body 80 during the installation process.

[0111] Optionally, in one embodiment, the first mounting member 11 includes a first fixing part 111 and a first supporting part 112 connected together, the first fixing part 111 being used to connect with the mounting surface 92. The first mounting member 11 is a wall-mounted panel, the second mounting member 12 is an inner wall-mounted bracket, and the third mounting member 13 is an outer wall-mounted bracket.

[0112] The second mounting member 12 and the third mounting member 13 both have cross-sections resembling an inverted U-shape. The second mounting member 12 includes a second front side plate 121, a second top plate 122 connected to the second front side plate 121, and a second rear side plate 123 connected to the second top plate 122. A first groove 1201 is formed between the second front side plate 121, the second top plate 122, and the second rear side plate 123. The third mounting member 13 includes a third front side plate 131, a third top plate 132 connected to the third front side plate 131, and a third rear side plate 133 connected to the third top plate 132. A second groove 1301 is formed between the third front side plate 131, the third top plate 132, and the third rear side plate 133. The second mounting member 12 is fastened to the top and outer side of the first mounting member 11, and the third mounting member 13 is fastened to the top and outer side of the second mounting member 12. The second mounting member 12 is inserted into the second groove 1301. The third front side plate 131, the second front side plate 121, the second rear side plate 123, and the third rear side plate 133 are distributed from front to back. The second top plate 122 is located between the first support portion 112 and the third top plate 132. Optionally, the first support portion 112 is inserted into the first groove 1201, and the second front side plate 121 and the second rear side plate 123 are located on the front and rear sides of the first support portion 112. The second mounting member 12 is inserted into the second groove 1301, and the third front side plate 131 and the third rear side plate 133 are located on the front and rear sides of the second mounting member 12.

[0113] In the embodiment, the second mounting member 12 and the third mounting member 13 are similar in structure, are brackets in approximate U shape, are similar in manufacturing process, and are low in manufacturing cost. For example, the main body structures of the second mounting member 12 and the third mounting member 13 can be formed by bending sheet metal. In addition, the relative movement between the second mounting member 12 and the first mounting member 11 and the relative movement between the third mounting member 13 and the second mounting member 12 are limited, the second mounting member 12 is not easily detached from the first mounting member 11, and the third mounting member 13 is not easily detached from the second mounting member 12, so that the screen body 80 is stably and reliably hung on the mounting surface 92 by the first wall hanging assembly 10.

[0114] Optionally, the second front side plate 121 and the third front side plate 131 are connected by the connecting structure 15, and the second rear side plate 123 and the third rear side plate 133 are connected by the connecting structure 15. In this way, the second mounting member 12 and the third mounting member 13 are connected in a way that they can slide up and down in the front and rear sides. When the position of the screen body 80 needs to be adjusted, the third mounting member 13 is operated to slide up and down relative to the second mounting member 12 by the first adjusting member 14, so as to adjust the position of the screen body 80. The connecting structure 15 in the front and rear sides makes the up and down movement of the third mounting member 13 more smooth and stable, and the adjustment is reliable.

[0115] In other embodiments, the second mounting member 12 and the third mounting member 13 are not provided with rear side plates, but are provided with front side plates and top plates only. In other embodiments, the second mounting member 12 and the third mounting member 13 can also have other structures.

[0116] Optionally, the second front side plate 121 and the second rear side plate 123 are provided with mounting through holes 1202, and the third front side plate 131 and the third rear side plate 133 are provided with vertical sliding grooves 1302 extending in the up and down directions. A part of the connecting structure 15 passes through the mounting through hole 1202 of the second front side plate 121 and is slidably mounted in the vertical sliding groove 1302 of the third front side plate 131, so as to connect the second front side plate 121 and the third front side plate 131 in a sliding manner. A part of the connecting structure 15 passes through the mounting through hole 1202 of the second rear side plate 123 and is slidably mounted in the vertical sliding groove 1302 of the third rear side plate 133, so as to connect the second rear side plate 123 and the third rear side plate 133 in a sliding manner. It can be understood that the vertical sliding groove 1302 provides the up and down sliding connection between the third mounting member 13 and the second mounting member 12. The mounting through hole 1202 can be a circular hole, and the vertical sliding groove 1302 can be a strip-shaped hole, also known as a runway-shaped hole, a long strip hole, a long circular hole, etc.

[0117] In the embodiment, when the first adjusting member 14 is rotated for adjusting the up-down position of the third mounting member 13, the third mounting member 13 is guided by the vertical sliding groove 1302 to move stably relative to the second mounting member 12, so that the operator can accurately adjust the up-down position of the screen body 80 by the cooperation of the first adjusting member 14 and the vertical sliding groove 1302.

[0118] In an embodiment, when the second mounting member 12 and the third mounting member 13 respectively comprise a front plate, a top plate and a back plate, the first adjusting member 14 is arranged in the following manner. The upper side of the second top plate 122 of the second mounting member 12 has a second supporting surface, i.e., the side of the second top plate 122 close to the third top plate 132 has the second supporting surface. The third top plate 132 is provided with a first adjusting hole 1321, the first adjusting member 14 passes through the first adjusting hole 1321, the first adjusting member 14 is threadedly connected with the first adjusting hole 1321, and the end of the first adjusting member 14 abuts against the second supporting surface. The first adjusting member 14 can be, but is not limited to, a threaded stud. By the cooperation of the thread engagement force and the abutting force, when the first adjusting member 14 is rotated, the third mounting member 13 drives the screen body 80 to move upward or downward along the first adjusting member 14 relative to the second mounting member 12 under the action of the counterforce.

[0119] Next, on the basis that the third mounting member 13 is slidably connected with the second mounting member 12 in the up-down direction by the connecting structure 15, the first mounting assembly of the present application is further described as follows:

[0120] Please continue to refer to Figure 2 、 Figure 8 、 Figures 10 to 19 In an embodiment, in addition to being used for slidably connecting the third mounting member 13 with the second mounting member 12, the connecting structure 15 also has the function of reducing the resistance of the second mounting member 12 to move leftward or rightward relative to the first mounting member 11.

[0127] The first connecting shaft 1511 passes through the vertical slide groove 1302 of the third front side plate 131, through the mounting hole 1202 of the second front side plate 121, through the second groove 1301, and through the mounting hole 1202 of the second rear side plate 123; the first connecting member 151 can rotate relative to the second mounting member 12.

[0128] The second connecting piece 153 is configured to include a second connecting shaft 1531 and a second limiting portion 1532 extending along the outer periphery of one end of the second connecting shaft 1531, the second limiting portion 1532 is located on the side of the third rear side plate 133 away from the second rear side plate 123, the second connecting shaft 1531 passes through the vertical sliding slot 1302 of the third rear side plate 133, and one end of the second connecting shaft 1531 away from the second limiting portion 1532 is connected with the first connecting shaft 1511.

[0129] The first limiting portion 1512 and the second limiting portion 1532 are configured to prevent the first connecting piece 151 and the second connecting piece 153 from being pulled out of the third mounting piece 13.

[0130] The third configuration mode of the connecting structure 15 is as follows:

[0131] The connecting structure 15 includes the first connecting piece 151 and the second connecting piece 153, and the configuration mode of the first connecting piece 151 is consistent with the configuration mode of the connecting mode.

[0132] Referring to Figure 17 The second connecting piece 153 is configured to be a limiting cap, the second connecting piece 153 is in limiting cooperation with the side of the third rear side plate 133 away from the second rear side plate 123, and the first connecting shaft 1511 passes through the mounting through hole 1202 of the second rear side plate 123 and the vertical sliding slot 1302 of the third rear side plate 133 to be connected with the second connecting piece 153.

[0133] In the above-mentioned first, second and third configuration modes of the connecting structure 15, the connecting structure 15 is configured to be at least partially a rotatable part, the rotatable part is rotatably and rollably installed between the first support part 112 of the first mounting piece 11 and the second top plate 122 of the second mounting piece 12, so that in the case that the third mounting piece 13 moves relative to the second mounting piece 12 in the left-right direction and the part of the connecting structure 15 between the first support part 112 and the second top plate 122 rotates, the following effects are achieved:

[0134] When the positions of the screen bodies 80 need to be adjusted, multiple installers do not need to lift the screen bodies 80 again, and the installers can directly push the screen bodies 80 left and right, thereby reducing the labor intensity and difficulty of the installers in adjusting the two screen bodies 80 to the side abutting state, improving the splicing tightness between the adjacent screen bodies 80, reducing or avoiding the splicing gap, and the adjustment process is easier. The connecting structure 15 reduces the difficulty of on-site installation, improves the problem of inconvenient lifting and difficult installation caused by the heavy weight of the screen bodies 80 on the installation site, and makes the installation more convenient and time-saving.

[0135] In the above-mentioned configuration modes one, two and three of the connecting structure 15, the lower side of the portion of the connecting structure 15 located inside the first recess 1201 and on the upper side of the first support part 112 (such as the first connecting shaft 1511 of the intermediate shaft 152 or the first connecting member 151) is in abutment with the first support part 112. In this way, the weight borne by the second mounting member 12 can be transmitted to the connecting structure 15, and the connecting structure 15 is used to transmit the weight at the second mounting member 12 to the first support part 112. In this way, the difficulty of moving the screen body 80 leftward and rightward can be reduced, the friction is minimized, and direct contact between the upper surface of the first support part 112 and the lower surface of the second mounting member is avoided. After the screen body 80 is hung to the mounting surface 92 by the first wall-hung assembly 10, the frictional resistance of the screen body 80 moving leftward and rightward is smaller, and the resistance of the screen body 80 moving leftward and rightward can be reduced to a greater extent.

[0136] In other embodiments, with reference to Figure 18 , the connecting structure 15 only functions to slidingly connect the third mounting member 13 and the second mounting member 12 in the up-down direction. On this basis, a rolling structure 16 is further arranged between the second mounting member 12 and the first mounting member 11. The first mounting assembly 10 further comprises the rolling structure 16, the rolling structure 16 is arranged in the first recess 1201, the rolling structure 16 is arranged on the top of the first support part 112, and the rolling structure 16 is rotatably mounted to the second mounting member 12 or the first support part 112; the rolling structure 16 is used to rotate when the second mounting member 12 moves relative to the first mounting member 11 in the left-right direction. Exemplarily, the third front side plate 131 and the second front side plate 121 are slidingly connected by the first connecting member 151 of the connecting structure 15, and the third rear side plate 133 and the second rear side plate 123 are slidingly connected by the second connecting member 153 of the connecting structure 15.

[0137] It can be understood that the arrangement of the rolling structure 16 also functions to reduce the resistance of the third mounting member 13 moving relative to the second mounting member 12 in the left-right direction. The effect of the rolling structure 16 is similar to that of the intermediate shaft 152 in the configuration mode one of the connecting structure 15 and the first connecting member 151 in the configuration mode two of the connecting structure 15.

[0138] With reference to Figures 1 to 7The spliced screen includes at least two screen bodies 80, and further includes the mounting assembly. The rear side of at least one screen body 80 is provided with the mounting assembly, and the mounting assembly is used for mounting the screen body 80 to the mounting surface 92. The third mounting member 13 is connected with the screen body 80, and the first mounting member 11 is used for being fixed to the wall surface. When the screen body 80 is mounted to the mounting surface 92 through the first wall hanging assembly 10, if an external force pushes the screen body 80 to move in the left-right direction, the screen body 80 drives the third mounting member 13 and the second mounting member 12 to move in the left-right direction relative to the first mounting member 11, and the connecting structure 15 or the rolling structure 16 can rotate under the action of friction. The first adjusting member 14 can be used for adjusting the up-down position or the front-rear position of the third mounting member 13 relative to the second mounting member 12, so as to adjust the up-down position or the front-rear position of the screen body 80 relative to the mounting surface 92.

[0139] For the spliced screen with a large number of screen bodies 80, the positions of the screen bodies 80 in multiple directions are adjusted, so that the splicing integrity between every two screen bodies 80 is better, and the installation effect of the entire large spliced screen is better, the uniform small gap or seamless splicing is realized, the display surface 82 of the spliced screen is flat, the display effect is better, and the touch writing experience is better. The spliced screen of the present application reduces the difficulty of on-site installation and is more convenient and time-saving to install.

[0140] In an embodiment, after the positions between the adjacent screen bodies 80 are adjusted in place, the adjacent screen bodies 80 are connected through the locking member 30, so that the relative fixation of the left-right position, the up-down position and the front-rear position between the adjacent screen bodies 80 is realized, and the spliced screen is kept in the current matching state.

[0141] In an embodiment, the first adjusting member 14 is configured to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12, and at least part of the structure of the first adjusting member 14 extends in the up-down direction.

[0142] The inventor found in the process of researching the installation scheme of the single screen body 80 in the installation process of the spliced screen that if the third mounting piece 13 and the first adjusting piece 14 are not arranged in the first wall-mounted assembly 10, that is, the first wall-mounted assembly 10 does not have the function of adjusting the up-down position of the screen body 80, then in the installation process of the screen body 80, although the left-right position adjustment of the screen body 80 is more labor-saving and convenient through the cooperation of the first mounting piece 11, the connecting structure 15 or the rolling structure 16, and the second mounting piece 12. However, if the installer finds that the screen body 80 needs to be adjusted upward as a whole after the first mounting piece 11 is fixed to the installation surface 92, the second mounting piece 12 is fixed to the rear side of the screen body 80, and the left-right position of the screen body 80 is adjusted, and then lifts the screen body 80 upward according to the up-down alignment requirement, the second mounting piece 12 will be lifted upward with the screen body 80. At this time, the first mounting piece 11 may not be able to provide upward supporting force to the second mounting piece 12, and at this time, the rolling friction generated by the connecting structure 15 or the rolling structure 16 between the second mounting piece 12 and the first mounting piece 11 may not be able to reduce the resistance of the left-right movement of the screen body 80.

[0143] Importantly, in the present embodiment, the up-down position adjustment function of the screen body 80 is integrated in the third mounting piece 13 and the second mounting piece 12 of the first wall-mounted assembly 10. When the up-down position of the screen body 80 needs to be adjusted (for example, in the case of Figure 22 ), referring to Figure 11 , only the first adjusting piece 14 needs to be operated to adjust the up-down position of the third mounting piece 13 relative to the second mounting piece 12. This adjustment operation will not affect the relative position between the second mounting piece 12 and the first mounting piece 11. The first mounting piece 11, the connecting structure 15 or the rolling structure 16, and the second mounting piece 12 can remain reliable cooperation when adjusting the up-down position of the screen body 80. The second mounting piece 12 can remain reliable support for the first mounting piece 11, and the connecting structure 15 or the rolling structure 16 can also be used to reduce the frictional resistance of the left-right movement of the second mounting piece 12 relative to the first mounting piece 11.

[0144] In other words, by arranging the first adjusting piece 14 for adjusting the up-down position of the screen body 80 between the third mounting piece 13 and the second mounting piece 12 in the first wall-mounted assembly 10, the connecting structure 15 or the rolling structure 16 remains in cooperation with the first mounting piece 11 and the second mounting piece 12 during the up-down position adjustment of the screen body 80. The left-right position and the up-down position of the screen body 80 can be adjusted simultaneously, without affecting each other, and can be adjusted at any time. The first mounting piece 11 can continuously support the second mounting piece 12, increasing the support points that can provide upward support to the screen body 80 when the screen body 80 is hung on the installation surface 92, and ensuring that the screen body 80 can be hung on the installation surface 92 through more force points.

[0145] It should be noted that in other embodiments, the first adjusting member 14 can also be configured to adjust the front-back position of the third mounting member 13 relative to the second mounting member 12, and the first adjusting member 14 at least partially extends in the front-back direction.

[0146] For the convenience of understanding, in the following embodiments, the first adjusting member 14 is taken as an example to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12, and the mounting assembly and the tiled screen are described.

[0147] Optionally, referring to Figure 1 , Figures 4 to 6 , the mounting assembly further comprises a second wall-hanging assembly 20 configured to be arranged at the rear side of the screen body 80; the second wall-hanging assembly 20 comprises a fourth mounting member 21 and a second adjusting member 23 arranged on the fourth mounting member 21; when the second wall-hanging assembly 20 is arranged between the screen body 80 and the mounting surface 92, the fourth mounting member 21 is configured to be mounted on the screen body 80, and the second adjusting member 23 is configured to adjust the front-back position of the screen body 80 relative to the mounting surface 92.

[0148] Optionally, the first adjusting member 14 at least partially extends in the up-down direction, and the second adjusting member 23 at least partially extends in the front-back direction. For example, the first adjusting member 14 is configured to provide a counterforce for upward movement of the third mounting member 13 and the screen body 80 by abutting against the second mounting member 12 downward, so as to adjust the position of the screen body 80 upward. For example, the second adjusting member 23 is configured to provide a counterforce for forward movement of the fourth mounting member 21 and the screen body 80 by abutting against the mounting surface 92 directly or indirectly rearward, so as to adjust the position of the screen body 80 forward.

[0149] For example, when the upper side of the first screen body 80 is higher than the upper side of the second screen body 80, the position of the second screen body 80 can be adjusted upward as a whole by operating the first adjusting member 14 at the rear side of the second screen body 80 until the upper side of the second screen body 80 is flush with the upper side of the first screen body 80. Similarly, when the display surface 82 of the first screen body 80 protrudes forward relative to the display surface 82 of the second screen body 80, the position of the second screen body 80 can be adjusted forward as a whole by operating the second adjusting member 23 at the rear side of the second screen body 80 until the display surface 82 of the second screen body 80 is flush with the display surface 82 of the first screen body 80.

[0150] The installation components and splicing screen in this embodiment, through the cooperation of the first wall-mounting component 10 and the second wall-mounting component 20, can adjust the position of the screen 80 in multiple directions, including left and right, up and down, and front and back. This solves problems such as inaccurate left and right positions, misalignment of up and down positions, misalignment of front and back positions, and uneven splicing gaps and uneven steps between screens 80 caused by tilting after the screen 80 is mounted on the wall. The splicing gaps between adjacent screens 80 can be reduced or eliminated, resulting in smaller and flatter steps between adjacent screens 80.

[0151] This embodiment can achieve the adjustment of the screen body 80's position in three degrees of freedom during installation by using four types of mounting components: the first mounting component 11, the second mounting component 12, the third mounting component 13, and the fourth mounting component 21. Compared with the scheme that uses six types of mounting components and three sets of wall-mounted components to adjust the position in three degrees of freedom, the mounting component structure of this embodiment is simpler and has fewer parts.

[0152] In this embodiment, the first adjusting member 14 for adjusting the vertical position of the screen 80 is configured in the first wall-mounted assembly 10, and the second adjusting member 23 for adjusting the front-back position of the screen 80 is configured in the second wall-mounted assembly 20, which is more reasonable. Figures 4 to 7 As shown, the fourth mounting member 21 can be fixed to the edge area of ​​the rear side of the screen body 80 (such as the edge plate portion 913 of the back panel 91). The reserved distance between the edge area of ​​the rear side of the screen body 80 and the mounting surface 92 is larger, which can better accommodate the fourth mounting member 21 and the second adjusting member 23 extending in the front-rear direction. Correspondingly, the third mounting member 13 is fixed to the middle area of ​​the rear side of the screen body 80 (such as the middle plate portion 911 of the back panel 91). Most of the weight of the screen body 80 can be borne by the first wall-mounting assembly 10. The middle plate portion 911 of the back panel 91 has high structural strength, so the screen body 80 can be reliably supported by the first wall-mounting assembly 10.

[0153] To facilitate understanding, the principle of using the first wall-mounted component 10 to adjust the vertical position of the screen 80 and the second wall-mounted component 20 to adjust the front-back position of the screen 80 in this embodiment will be further explained: For example... Figure 20As shown, when the screen body 80 is installed, the gap space at the rear side of the screen body 80 (i.e. the interval space between the rear side surface of the screen body 80 and the installation surface 92) is a space for accommodating the installation assembly. However, the rear side surface of some screen bodies 80 is not flat, and the back plate 91 of the screen body 80 includes a middle plate portion 911, an edge plate portion 913, and a connecting plate portion 912, the middle plate portion 911 is convex backward relative to the edge plate portion 913, and the connecting plate portion 912 is inclined to connect the middle plate portion 911 and the edge plate portion 913, and the entire screen body 80 has a shape of being thick in the middle and thin at the edges, and the back plate 91 is similar to a bowl shape. The interval d between the middle plate portion 911 and the installation surface 92 is smaller than the interval d between the edge plate portion 913 and the installation surface 92. In the case where the first installation piece 11 is arranged between the middle plate portion 911 and the installation surface 92, the front-rear direction size of the first installation piece 11 has already occupied the front-rear distance of the originally relatively compact gap space, and the front-rear interval reserved for the front-rear adjusting piece between the rear side surface of the screen body 80 and the front side of the first installation piece 11 is very small, and therefore, it is difficult to arrange the adjusting piece for adjusting the front-rear interval of the screen body 80 between the screen body 80 and the first installation piece 11, which extends at least in the front-rear direction.

[0154] It can be understood that in some cases in the related art, the position requirement of the screen body 80 is not high, and when the screen body 80 is installed, the position of the screen body 80 is adjusted by manually directly lifting the screen body 80, which may not achieve more precise adjustment of the position of the screen body 80 due to the heavy weight of the screen body 80 and the difficulty of cooperation of multiple people, but can meet the installation requirements. However, for some spliced screens, the relative position between the screen body 80 and the screen body 80 is required to be high, and exemplarily, after the installation of the entire spliced screen is completed, it is required that when the spliced screen is viewed from the front, the display area of the spliced screen appears without gaps and black edges, so that the user feels that the entire spliced screen is a large screen rather than multiple small screens when the spliced screen displays a picture, and it is required that when the entire spliced screen is viewed from the left side or the right side of the spliced screen, the front side surface of the entire spliced screen is flat. At this time, the first wall hanging assembly 10 and the second wall hanging assembly 20 of the present application are used to install the screen body 80, which can adjust the left-right position, the up-down position, and the front-rear position of the screen body 80, and can meet higher position requirements of the screen body 80 and splicing requirements between the screen bodies 80.

[0155] In an embodiment, the position requirement between the adjacent screen bodies 80 is high during the installation of the screen bodies 80 to the installation surface 92, and the installation assembly of the present application can meet the higher-precision adjustment requirement of the position of the screen bodies 80. An example of the tiled screen with high position requirement between the adjacent screen bodies 80 is provided: each screen body 80 of the tiled screen includes a main display module, there is no frame between the adjacent main display modules in the tiled screen, and a secondary display module is installed between the adjacent main display modules after the adjacent screen bodies 80 are installed to the installation surface 92. The secondary display module can shield the fixing structure between the adjacent screen bodies 80 for connection and fixation. Thus, from the front of the tiled screen, the main display module, the secondary display module, and the main display module are tiled from left to right between the adjacent two screen bodies 80, there is no frame between the adjacent display modules, there is no black border area, it is more beautiful, and the cross-screen touch operation and writing can be realized, so that the entire tiled screen looks like a large display screen and has high integrity. The secondary display module can be, but is not limited to, a mini LED (min iLED) display module. Among them, the left-right tiling effect between the adjacent screen bodies 80 can make the left-right interval between the adjacent main display modules accommodate the secondary display module, the up-down and front-back alignment effects between the adjacent screen bodies 80 are good, and the flatness between the main display module, the secondary display module, and the main display module can be improved, and the display effect is good.

[0156] In an embodiment, the structure of the first wall-mounted assembly 10 is described and exemplified in more detail.

[0157] The first adjusting member 14 is used to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12, and the first mounting member 11 includes a first fixing part 111 and a first supporting part 112 connected to each other. The first fixing part 111 is used to be connected to the installation surface 92. Exemplarily, the first fixing part 111 can be fixed to the installation surface 92 by screwing, welding, riveting, or the like.

[0158] In an embodiment, the fourth mounting member 21 is a bracket, the fourth mounting member 21 is provided with a second adjusting hole, and the second adjusting member 23 can be, but is not limited to, a stud. The second adjusting member 23 passes through the second adjusting hole from front to back, and the rear end of the second adjusting member 23 directly or indirectly abuts against the installation surface 92. By using the thread engagement force and the mutual abutting force, when the second adjusting member 23 is rotated, the fourth mounting member 21 drives the screen body 80 to move forward or backward along the second adjusting member 23 relative to the installation surface 92 under the action of the counterforce.

[0159] Reference Figure 1 , Figure 7The first mounting member 11 is a wall-mounted panel extending in the left-right direction. The first wall-mounted assembly 10 includes a plurality of second mounting members 12 and a plurality of third mounting members 13. The plurality of second mounting members 12 are hung on the first mounting member 11 at intervals in the left-right direction, that is, the first mounting member 11 supports the plurality of second mounting members 12. At least two second mounting members 12 are equipped with third mounting members 13, that is, the screen 80 transfers its weight to the first mounting member 11 through the plurality of third mounting members 13 and the plurality of second mounting members 12.

[0160] The first mounting component 11 is a wall-mounted panel extending in the left-right direction. Firstly, the first wall-mounting assembly 10 primarily supports and bears the overall weight of the screen 80. The first mounting component 11 is designed as a long, narrow wall-mounted panel structure. It can be secured to the mounting surface 92 using multiple fasteners. The stronger the fixation between the first mounting component 11 and the mounting surface 92, the greater the weight it can support, thus providing more reliable support for the heavy screen 80. Secondly, the first mounting component 11 extends in the left-right direction and has a certain length. It provides a sliding track for the second mounting component 12 and the screen 80, facilitating the left-right movement of the screen 80 after it is hung by the first wall-mounting assembly 10, allowing it to be pushed laterally towards another screen 80. Thirdly, when the mounting component provides a guide rail for the left and right movement of the screen 80, the screen 80 cooperates with the first mounting component 11 through multiple spaced second mounting components 12. This allows for stable support of the screen 80 by distributing support at multiple locations, while simultaneously reducing the weight and volume of the second mounting components 12 and lightening the load on the first mounting component 11. Fourthly, when first wall-mounting components 10 are provided on the rear sides of two adjacent screens 80 in the left and right directions, the use of multiple spaced second mounting components 12 in each first wall-mounting component 10 can reduce the size of the second mounting components 12 in the left and right directions. This can prevent interference between the second mounting components 12 in adjacent components after the screens 80 approach and abut against each other on their left and right sides. Fifthly, the connecting structure 15 or the rolling structure 16 is rotatably mounted on the second mounting member 12. When the first mounting member 11 is a long strip structure extending in the left-right direction and multiple second mounting members 12 are spaced apart, if the connecting structure 15 or the rolling structure 16 is arranged on the long first mounting member 11, a large number of connecting structures 15 or rolling structures 16 need to be arranged on the first mounting member 11 so that the second mounting members 12 can contact the connecting structure 15 or the rolling structure 16 during the lateral movement. However, in this embodiment, the connecting structure 15 or the rolling structure 16 is mounted on the second mounting member 12, which can maintain rolling friction between each second mounting member 12 and the first mounting member 11 and reduce the number of connecting structures 15 or the rolling structure 16.

[0161] In an embodiment, at least two first connecting structures 15 or rolling structures 16 are arranged in each second mounting member 12 in the left-right direction, improving the smoothness of the left-right sliding of the second mounting member 12 on the first mounting member 11.

[0162] In other embodiments, the first wall-hanging assembly 10 can also include a plurality of first mounting members 11 and one long second mounting member 12.

[0163] In an embodiment, the first adjusting member 14 is used to adjust the up-down position of the third mounting member 13 relative to the second mounting member 12, and the mounting assembly further includes a second wall-hanging assembly 20, and a second adjusting member 23 is used to adjust the front-rear position of the fourth mounting member 21 relative to the mounting surface 92. On this basis, the arrangement positions of the first wall-hanging assembly 10 and the second wall-hanging assembly 20 are arranged in the following manner.

[0164] The screen body 80 has four corners, and the corners of the screen body 80 are positions near the intersection of adjacent two outer edges of the screen body 80. The four corners are respectively a left upper corner 811, a right upper corner 812, a left lower corner 813, and a right lower corner 814. Exemplarily, the left upper corner 811 is a region close to the intersection of the left side edge and the upper side edge of the screen body 80. Figure 7 In an embodiment, the dashed box selects a part of the rear side of the screen body 80 (the dashed box selects two first regions S1, two second regions S2, and two third regions S3. The two second regions S2 on the left and right sides are the left upper corner 811 and the right upper corner 812 on the rear side of the screen body 80, and the two third regions S3 on the left and right sides are the left lower corner 813 and the right lower corner 814 on the rear side of the screen body 80. The two first regions S1 are located between the two second regions S2 and close to the upper side edge of the screen body 80.

[0165] As shown in FIG. 1, the first wall-hanging assembly 10 is arranged close to the upper side of the screen body 80. Figure 7 Exemplarily, the first wall-hanging assembly 10 is arranged close to the upper side of the screen body 80. Moreover, the second mounting member 12 and the third mounting member 13 are arranged close to the middle region of the upper side of the screen body 80, that is, the assembly composed of the second mounting member 12, the third mounting member 13, and the first adjusting member 14 is arranged at the left upper corner 811 and the right upper corner 812 (between the two second regions S2).

[0166] The first wall-hanging assembly 10 is arranged close to the upper side of the screen body 80. Firstly, when the first adjusting member 14 is arranged to rotate and the bottom end abuts against the second mounting member 12 to pull the third mounting member and the screen body 80 upward by the reaction force, the arrangement of the first adjusting member 14 close to the upper side of the screen body 80 is more labor-saving and easier to realize than the arrangement of the first adjusting member 14 close to the lower side of the screen body 80. Secondly, the arrangement of the first wall-hanging assembly 10 close to the upper side of the screen body 80 makes it easier for the operator to operate the first adjusting member 14 through the gap between the upper side of the screen body 80 and the mounting surface 92. Thirdly, the first mounting member 11 fixed to the mounting surface 92 mainly supports the weight of the screen body 80, and the arrangement of the first mounting member 11 close to the upper side of the screen body 80 is conducive to improving the hanging center of gravity of the screen body 80 and stabilizing the hanging of the screen body 80.

[0167] Optionally, the first adjusting member 14 at least partially protrudes relative to the upper side edge of the screen body 80, and the operator can conveniently operate the operation part (such as the screw head) of the first adjusting member 14 protruding upward to rotate the first adjusting member 14 after the screen body 80 is hung on the mounting surface 92. Of course, the first adjusting member 14 can also be completely located at the rear side of the screen body 80.

[0168] Continuing as Figure 7 Illustrated, the four corner portions at the rear side of the screen body 80 are provided with the second wall-hanging assemblies 20, that is, the two second regions S2 and the two third regions S3 are provided with the second wall-hanging assemblies 20. In other embodiments, only the upper left corner portion 811 and the upper right corner portion 812 can be provided with the second wall-hanging assemblies 20, that is, the two second regions S2 are provided with the second wall-hanging assemblies 20. It can be understood that the second wall-hanging assemblies 20 arranged at the corner portions are used to cooperate with the first wall-hanging assembly 10 to provide auxiliary support and stabilize the screen body 80. Since the screen body 80 is hung on the mounting surface 92, the second wall-hanging assemblies 20 need to be arranged at least at the left and right corner portions at the upper side of the screen body 80 to stably support the upper side of the screen body 80 and prevent it from being easily overturned. When the second wall-hanging assemblies 20 are arranged at the four corner portions of the screen body 80, the hanging of the screen body 80 is more reliable.

[0169] In an embodiment, the two second wall hanging assemblies 20 arranged at the lower left corner 813 and the lower right corner 814 further comprise a fifth mounting member 22 for mounting on the mounting surface 92, the fifth mounting member 22 supports the fourth mounting member 21. In this way, when the first wall hanging assembly 10 is close to the upper side of the screen body 80, the upper side of the screen body 80 is mainly hung and fixed on the mounting surface 92 by the first mounting member 11 of the first wall hanging assembly 10, and the lower side of the screen body 80 is mainly hung and fixed on the mounting surface 92 by the fifth mounting member 22 of the second wall hanging assembly 20. The fourth mounting member 21 can be configured to be slidably connected to the fifth mounting member 22 in the front-rear direction, so that when it is necessary to adjust the front-rear position of the two corners of the lower side of the screen body 80, the screen body 80 and the fourth mounting member 21 can be moved forward and backward on the fifth mounting member 22 by rotating the second adjusting member 23.

[0170] In an embodiment, referring to Figure 1 、 Figure 7 The rear side of the screen body 80 is provided with a plurality of protruding longitudinal reinforcing ribs 83, each of which extends in the up-down direction, and the plurality of longitudinal reinforcing ribs 83 are arranged in the left-right direction. The longitudinal reinforcing ribs 83 strengthen the longitudinal bending strength of the screen body 80, and in the case of hanging the screen body 80 on the mounting surface 92, the screen body 80 mainly subjected to vertical stress is prevented from bending in the vertical direction.

[0171] Optionally, the plurality of second mounting members 12 and the plurality of third mounting members 13 of the first wall hanging assembly 10 are arranged in the left-right direction, and at least one longitudinal reinforcing rib 83 is provided with a third mounting member 13 or each longitudinal reinforcing rib 83 is provided with a third mounting member 13. Each third mounting member 13 is hung on a second mounting member 12. It can be understood that the weight of the screen body 80 acts on the plurality of third mounting members 13 from top to bottom, fixes the third mounting member 13 on the rear side of the longitudinal reinforcing rib 83, and makes the position bearing the gravity near the longitudinal reinforcing rib 83, which is beneficial to force transmission and avoids stress concentration, and improves the structural strength of the back plate 91 of the screen body 80.

[0172] Optionally, the first mounting member 11 is a wall hanging plate extending in the left-right direction and having a certain length, and the first mounting member 11 covers the rear side of at least two longitudinal reinforcing ribs 83, so as to provide a hanging position for the second mounting member 12 and the third mounting member 13 on the rear side of the longitudinal reinforcing rib 83 through the first mounting member 11.

[0173] Optionally, the first wall hanging assembly 10 can further comprise a fixing base 17, the front side of the fixing base 17 is shaped to match the rear side of the screen body 80, so that the front side of the fixing base 17 is just clamped on the rear side of the screen body 80. The fixing base 17 can be fixed to the rear side of the screen body 80 by means of fasteners or the like. The rear side of the fixing base 17 provides a flat surface to allow the third mounting member 13 to be stably and reliably mounted on the rear side of the fixing base 17. The third mounting member 13 can be fixed to the fixing base 17 by means of fasteners or the like. In the case where the protruding longitudinal reinforcing ribs 83 are provided on the rear side of the screen body 80, the provision of the fixing base 17 allows the third mounting member 13 to be stably mounted on the rear side of the screen body 80. In other embodiments, the third mounting member 13 can also be directly fixed to the rear side of the screen body 80.
