Description

Technical Field

[0001] This application relates to the field of LCD screen bracket technology, and in particular to mounting brackets, display modules, and projectors. Background Technology

[0002] The LCD screen is the core component of an LCD projector. In LCD projectors, the LCD screen is typically mounted on a mounting bracket to support and secure it.

[0003] In related technologies, the mounting bracket has mounting grooves that fit the contours of the LCD screen, and the LCD screen is embedded in the mounting grooves. The mounting bracket has multiple elastic clips that press against multiple positions on the edge of the LCD screen to fix the LCD screen in the mounting grooves.

[0004] During the process of inserting the LCD screen into the mounting slot, the screen needs to squeeze the elastic clips, causing them to deform and allowing the screen to enter the slot. Therefore, the LCD screen is prone to damage due to the pressure exerted between it and the elastic clips during insertion. Utility Model Content

[0005] Therefore, it is necessary to provide a mounting bracket, display module, and projector to address the problem that the LCD screen is easily damaged during the installation process due to the squeezing force between the mounting bracket and the elastic buckle in the related technology.

[0006] This application provides a mounting bracket, including a first mounting frame and a limiting member; the first mounting frame includes four support arms connected end to end in sequence, namely a first support arm and a second support arm parallel to a first direction, and a third support arm and a fourth support arm parallel to a second direction.

[0007] Side stops are fixedly connected to the outer edges of the first support arm, the second support arm, and the third support arm. Each side stop protrudes from the corresponding support arm to the same side in the third direction. The third direction, the second direction, and the first direction intersect each other.

[0008] At least one side stop arm is fixedly connected to a limiting arm along a third direction away from the corresponding support arm, and the limiting arm and the corresponding support arm of the same side stop arm are arranged opposite to each other.

[0009] The limiting member is located on the outer edge of the fourth support arm and engages with the fourth support arm. The limiting member protrudes from the fourth support arm in the same direction along a third direction.

[0010] In the aforementioned display module and projector, when the mounting bracket is used to install the LCD screen of the projector, the LCD screen is moved from the end of the mounting bracket equipped with the fourth support arm along the first direction into the first mounting frame until the four edges of the LCD screen overlap the four support arms respectively. Then, the limiting member is set on the outer edge of the fourth support arm and engages with the fourth support arm. During the installation process, the LCD screen can be protected from significant external pressure, thereby improving the safety of the LCD screen installation process and reducing the risk of LCD screen damage. After the LCD screen is installed in the mounting bracket, the side stops and limiting members fixedly connected to the outer edges of the first support arm, second support arm, and third support arm can respectively limit the lateral movement of the LCD screen on all four sides. The limiting arms and support arms can limit the LCD screen on both sides along the third direction, thus achieving six-sided limiting of the LCD screen and fully and reliably realizing the installation and positioning of the LCD screen.

[0011] In one embodiment, the side arm fixedly connected to the outer edge of the first support arm is the first side arm, and the side arm fixedly connected to the outer edge of the second support arm is the second side arm;

[0012] A first limiting arm is fixedly connected to the first side arm along the third direction away from the first support arm, and a second limiting arm is fixedly connected to the second side arm along the third direction away from the second support arm.

[0013] In this embodiment, the LCD screen is positioned by limiting the first limiting arm and the second limiting arm respectively, thereby improving the positional reliability of the LCD screen.

[0014] In one embodiment, a side arm fixedly connected to the outer edge of the third support arm is a third side arm, and a third limiting arm is fixedly connected to the side of the third side arm away from the third support arm along a third direction.

[0015] This embodiment uses a third limiting arm to limit the position of the LCD screen, further improving the positional reliability of the LCD screen.

[0016] In one embodiment, the limiting member includes a fourth side arm and an elastic locking portion connected to the fourth side arm, wherein the extension direction of the fourth side arm is along the second direction, and the elastic locking portion is engaged with the fourth support arm.

[0017] The fourth side arm is disposed on the outer edge of the fourth support arm, and the fourth side arm protrudes from the fourth support arm on the same side in a third direction.

[0018] In this embodiment, the fourth side arm limits the side of the LCD screen away from the third side arm. The fourth side arm extends along the second direction, meaning it is a longer arm structure along the second direction, thereby enabling sufficiently reliable limiting of the LCD screen away from the third side arm. The limiting member is reliably connected to the fourth support arm via an elastic locking part.

[0019] In one embodiment, the fourth support arm is provided with a first positioning hole, and the fourth side arm is provided with a first positioning post, the first positioning post and the first positioning hole are inserted and engaged in a third direction.

[0020] The first positioning pin and the first positioning hole are inserted and engaged along a third direction, facilitating the mutual positioning of the fourth side arm and the fourth support arm during the assembly of the limiting component. Furthermore, after the limiting component and the fourth support arm are assembled, the first positioning pin and the first positioning hole can be used for further positioning, ensuring a secure fit between the limiting component and the fourth support arm.

[0021] In one embodiment, the limiting member further includes a fifth side arm, one end of which is connected to one end of the fourth side arm, and the extension direction of the fifth side arm is along the first direction;

[0022] The fifth side arm is located on the outer edge of the first support arm and is spaced apart from the side arm (i.e. the first side arm) that is fixedly connected to the first support arm along the first direction.

[0023] When installing the LCD screen onto the mounting bracket, the limiting component is not initially installed on the first mounting frame. As the LCD screen with its display cable moves into the first mounting frame along the first direction, it is not obstructed by the fifth side arm, facilitating the arrangement of the display cable. After the LCD screen is in place, the limiting component is then placed on the outer edge of the fourth support arm and engages with it. At this point, the fifth side arm and the first side arm can jointly limit the LCD screen on one side along the second direction. This avoids the display cable and simultaneously limits the LCD screen from both sides of the display cable, improving the positional reliability of the LCD screen.

[0024] In one embodiment, the first support arm is provided with a second positioning hole, and the fifth side arm is provided with a second positioning post, the second positioning post and the second positioning hole are inserted and engaged in a third direction.

[0025] The second positioning post and the second positioning hole are inserted and engaged along the third direction, facilitating the mutual positioning of the fifth side stop arm and the first support arm during the assembly of the limiting component. Furthermore, after the limiting component and the fourth support arm are assembled, the second positioning post and the second positioning hole can be used for further positioning, ensuring a secure fit between the limiting component and the first and fourth support arms, and reducing the risk of displacement and deformation of the fifth side stop arm along the second direction.

[0026] In one embodiment, the resilient snap-fit ​​portion includes a body and a snap-fit ​​connector, with one end of the body along a third direction connected to a fourth side arm and the other end connected to the snap-fit ​​connector;

[0027] The fourth side arm abuts against one side surface of the fourth support arm along the third direction, and the snap-fit ​​connector abuts against the other side surface of the fourth support arm along the third direction.

[0028] The main body and the fourth support arm abut against each other along the first direction on the side away from the third support arm.

[0029] The fourth side stop and the locking connector abut against the two sides of the fourth support arm along the third direction, respectively, thus clamping the fourth support arm along the third direction. Simultaneously, the main body abuts against the side of the fourth support arm away from the third support arm along the first direction. This allows the fourth side stop, the main body, and the locking connector to jointly clamp the fourth support arm, achieving a reliable engagement with it.

[0030] In one embodiment, the fourth support arm is provided with a snap-fit ​​groove on the side away from the third support arm along the first direction, the main body cooperates with the snap-fit ​​groove, and abuts against the bottom of the snap-fit ​​groove along the first direction.

[0031] The main body is positioned by the snap-fit ​​groove, which facilitates assembly and allows the elastic snap-fit ​​part to cooperate more reliably with the fourth support arm.

[0032] In one embodiment, the mounting bracket further includes a second mounting frame, which includes four mounting units connected end to end in sequence. The second mounting frame is fixedly connected to the side of the four support arms of the first mounting frame facing away from the side arm.

[0033] The mounting unit includes a mounting arm and a side guard plate. The side guard plate is fixedly connected to the outer edge of the mounting arm and protrudes from the mounting arm in a third direction away from the support arm.

[0034] At least two opposite side guards have elastic locking protrusions at the ends away from the corresponding mounting arms, with the elastic locking protrusions protruding inwards towards the corresponding side guards.

[0035] The second mounting frame facilitates the installation and fixation of the Fresnel lens.

[0036] One embodiment of this application provides a display module, including a liquid crystal display (LCD) screen and a mounting bracket according to any of the above embodiments, wherein the LCD screen is mounted on the mounting bracket.

[0037] In the aforementioned display module, when the mounting bracket is used to install the LCD screen of a projector, the LCD screen is moved from the end of the mounting bracket equipped with the fourth support arm along the first direction into the first mounting frame until the four edges of the LCD screen overlap the four support arms. Then, a limiting member is placed on the outer edge of the fourth support arm and engages with it. During installation, the LCD screen is protected from significant external pressure, thus improving the safety of the installation process and reducing the risk of damage. After the LCD screen is installed in the mounting bracket, the side arms and limiting members fixedly connected to the outer edges of the first, second, and third support arms can respectively limit the lateral movement of the LCD screen on all four sides. The limiting arms and support arms can limit the LCD screen on both sides along the third direction, achieving six-sided limiting of the LCD screen and reliably realizing the installation and positioning of the LCD screen.

[0038] One embodiment of this application provides a projector, including a display module.

[0039] In the aforementioned projector mounting bracket, when mounting the projector's LCD screen, the LCD screen is moved from the end of the mounting bracket equipped with the fourth support arm along a first direction into the first mounting frame until the four edges of the LCD screen overlap the four support arms. Then, a limiting member is placed on the outer edge of the fourth support arm and engages with it. This design protects the LCD screen from significant external pressure during installation, improving safety and reducing the risk of damage. After the LCD screen is mounted on the bracket, the side arms and limiting members fixedly connected to the outer edges of the first, second, and third support arms provide lateral limiting for the LCD screen. The limiting arms and support arms also limit the LCD screen on both sides along a third direction, achieving six-sided limiting of the LCD screen and reliably ensuring its installation and positioning.

[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] As described in the background section, the mounting bracket has mounting grooves that fit the contours of the LCD screen, into which the LCD screen is embedded. The mounting bracket has multiple elastic clips that press against multiple points on the edge of the LCD screen to secure it within the mounting groove.

[0059] Before the LCD screen is inserted into the mounting slot, the elastic clips prevent it from entering. Therefore, during insertion, the LCD screen must squeeze the elastic clips, causing them to deform and allowing the screen to fit into the slot. Once inside, the clips return to their original shape, securing the screen's edges. The pressure exerted between the LCD screen and the elastic clips during insertion can easily cause damage to the screen.

[0060] Therefore, embodiments of this application provide a mounting bracket, a display module, and a projector. When installing the projector's LCD screen, the LCD screen is moved from one end of the mounting bracket equipped with a fourth support arm along a first direction into the first mounting frame until the four edges of the LCD screen overlap the four support arms. Then, a limiting member is placed on the outer edge of the fourth support arm and engages with it. During installation, the LCD screen is protected from significant external pressure, thereby improving the safety of the installation process and reducing the risk of damage to the LCD screen.

[0061] Please combine Figure 1 and Figure 2 One embodiment of this application provides a mounting bracket, which includes a first mounting frame and a limiting member. The first mounting frame includes four support arms connected end to end in sequence, namely a first support arm 110 and a second support arm 120 parallel to a first direction XX', and a third support arm 130 and a fourth support arm 140 parallel to a second direction YY'.

[0062] Side stops are fixedly connected to the outer edges of the first support arm 110, the second support arm 120, and the third support arm 130, respectively. Each side stop protrudes from the corresponding support arm on the same side of the third direction ZZ', and the third direction ZZ', the second direction YY', and the first direction XX' intersect each other. Optionally, the third direction ZZ', the second direction YY', and the first direction XX' are perpendicular to each other.

[0063] For details, please refer to Figure 2 The side arm fixedly connected to the outer edge of the first support arm 110 is the first side arm 210, the side arm fixedly connected to the outer edge of the second support arm 120 is the second side arm 220, and the side arm fixedly connected to the outer edge of the third support arm 130 is the third side arm 230.

[0064] Understandably, the four support arms, connected end to end, form the border of a quadrilateral, which in turn defines the interior space of the quadrilateral. The outer edges of each support arm refer to the edges of the support arms closest to the outer edge of the interior space of the quadrilateral. Figure 2 In the illustrated embodiment, each side stop arm protrudes from its corresponding support arm toward the OZ' side of the third direction ZZ'. Specifically, the first side stop arm 210, the second side stop arm 220, and the third side stop arm 230 protrude from their respective support arms toward the OZ' side of the third direction ZZ'.

[0065] At least one side stop arm is provided with a limit arm on the side away from the corresponding support arm along the third direction ZZ', and the limit arm and the corresponding support arm of the same side stop arm are arranged opposite to each other.

[0066] In other words, at least one side arm is fixedly connected to a limiting arm and a support arm on both sides along the third direction ZZ', and the support arm and the limiting arm are arranged opposite to each other along the third direction ZZ'.

[0067] The limiting member 400 is disposed on the outer edge of the fourth support arm 140 and engages with the fourth support arm 140. The limiting member 400 protrudes from the fourth support arm 140 along the third direction ZZ' towards the same side. That is, the limiting member 400 protrudes from the fourth support arm 140 towards the OZ' side of the third direction ZZ'.

[0068] When the aforementioned mounting bracket is used to mount the LCD screen 10 of a projector, the limiting member 400 is not initially installed on the first mounting frame; at this time, the mounting bracket is... Figure 2 In the indicated state, the LCD screen 10 is not obstructed by the limiting member 400. Therefore, the LCD screen 10 is moved from the end of the mounting bracket with the fourth support arm 140 along the first direction XX' into the first mounting frame. Understandably, during the moving process, the LCD screen 10 rests on the second support arm 120 and the fourth support arm 140 on both sides along the second direction YY', and slides along the second support arm 120 and the fourth support arm 140 along the first direction XX' until one end of the LCD screen 10 rests on the third support arm 130 and the other end rests on the fourth support arm 140, so that the four support arms can support the LCD screen 10 along the third direction ZZ'. Finally, the limiting member 400 is set on the outer edge of the fourth support arm 140 and engaged with the fourth support arm 140.

[0069] Since the outer edges of the first support arm 110, the second support arm 120, and the third support arm 130 are respectively fixedly connected with side stops, and each side stop protrudes from the corresponding support arm on the same side in the third direction ZZ', the first side stop 210, the second side stop 220, and the third side stop 230 can respectively limit the three circumferential sides of the LCD screen 10. Specifically, the first side stop 210 and the second side stop 220 can limit the LCD screen 10 on both sides along the second direction YY', and the third side stop 230 can limit the LCD screen 10 on one side along the first direction XX'. Since the limiting member 400 is provided on the outer edge of the fourth support arm 140, and the limiting member 400 protrudes from the fourth support arm 140 on the same side in the third direction ZZ', the limiting member 400 can limit the LCD screen 10 on the side away from the third side stop 230 along the first direction XX'. In this way, the lateral limiting of the LCD screen 10 is achieved.

[0070] Furthermore, since at least one side stop arm is fixedly connected to a limiting arm on the side away from the corresponding support arm along the third direction ZZ', and the limiting arm and the corresponding support arm of the same side stop arm are arranged opposite to each other, the limiting arm can limit the LCD screen 10 on the side away from the support arm along the third direction ZZ'. That is, the LCD screen 10 is located between the limiting arm and the support arm along the third direction ZZ'.

[0071] Therefore, it can be seen that, through the mounting bracket of this embodiment, the first side arm 210 and the second side arm 220 can limit the LCD screen 10 on both sides along the second direction YY', the third side arm 230 and the limiting member 400 can limit the LCD screen 10 on both sides along the first direction XX', and the limiting arm and the supporting arm can limit the LCD screen 10 on both sides along the third direction ZZ', that is, the six sides of the LCD screen 10 are limited, and the installation and positioning of the LCD screen 10 are fully and reliably realized.

[0072] When the aforementioned mounting bracket is used to mount the LCD screen 10 of a projector, the LCD screen 10 is moved from one end of the mounting bracket with the fourth support arm 140 along the first direction XX' into the first mounting frame until the four edges of the LCD screen 10 overlap the four support arms. Then, the limiting member 400 is positioned on the outer edge of the fourth support arm 140 and engages with it. During installation, the LCD screen 10 is protected from significant external pressure (such as the squeezing force between the LCD screen and the elastic clip in related technologies), thereby improving the safety of the installation process and reducing the risk of damage to the LCD screen 10. After the LCD screen 10 is installed on the mounting bracket, the side arms and limiting members 400 fixedly connected to the outer edges of the first support arm 110, the second support arm 120, and the third support arm 130 can respectively limit the LCD screen 10 laterally around its four sides. The limiting arms and support arms can limit the LCD screen 10 on both sides along the third direction ZZ', thus realizing the six-sided limiting of the LCD screen 10, and fully and reliably realizing the installation and positioning of the LCD screen 10.

[0073] Moreover, the six-sided limiting of the LCD screen 10 by the side arm and limiting member 400, the limiting arm and the support arm are achieved by directional arrangement, which does not require strong compression of the LCD screen 10 to keep it fixed, thus allowing the LCD screen 10 to be free from large fixing pressure (such as the clamping pressure of elastic buckles in related technologies).

[0074] Understandably, the length direction of the first side arm 210 is the same as that of the first support arm 110, both along the first direction XX'. The length direction of the second side arm 220 is the same as that of the second support arm 120, both along the first direction XX'. The length direction of the third side arm 230 is the same as that of the third support arm 130, both along the second direction YY'.

[0075] The length direction of the limiting arm is the same as the length direction of the side stop arm it is connected to. Unlike the prior art which uses elastic clips to press against a localized area of ​​the LCD screen 10, this embodiment uses a limiting arm to limit the LCD screen 10 along the third direction ZZ' on the side opposite to the support arm. The limiting arm can be made into a relatively long arm structure, thereby increasing the contact area with the LCD screen 10, reducing stress concentration during contact, and thus making the LCD screen 10 less prone to damage. For example, the length of the limiting arm can be greater than 1 / 3 of the length of the side stop arm it is connected to.

[0076] Please refer to Figure 2 In one embodiment, a first limiting arm 310 is fixedly connected to the side of the first side arm 210 away from the first support arm 110 along the third direction ZZ', and a second limiting arm 320 is fixedly connected to the side of the second side arm 220 away from the second support arm 120 along the third direction ZZ'.

[0077] Specifically, the first limiting arm 310 and the first support arm 110 are arranged opposite each other along the third direction ZZ', and the second limiting arm 320 and the second support arm 120 are arranged opposite each other along the third direction ZZ'.

[0078] In this embodiment, the LCD screen 10 is positioned by limiting the first limiting arm 310 and the second limiting arm 320 respectively, thereby improving the positional reliability of the LCD screen 10.

[0079] Please refer to Figure 2 In one embodiment, the third side arm 230 is fixedly connected to the third limiting arm 330 on the side of the third side arm 230 away from the third support arm 130 along the third direction ZZ'.

[0080] Specifically, the third limiting arm 330 and the third support arm 130 are arranged opposite each other along the third direction ZZ'.

[0081] In this embodiment, the third limiting arm 330 limits the position of the LCD screen 10, thereby further improving the positional reliability of the LCD screen 10.

[0082] Please combine Figures 1 to 3 In one embodiment, the limiting member 400 includes a fourth side arm 410 and an elastic locking portion 420 connected to the fourth side arm 410. The fourth side arm 410 extends along the second direction YY', and the elastic locking portion 420 is engaged with the fourth support arm 140.

[0083] The fourth side arm 410 is disposed on the outer edge of the fourth support arm 140, and the fourth side arm 410 protrudes from the fourth support arm 140 along the third direction ZZ' towards the same side. That is, the fourth side arm 410 protrudes from the fourth support arm 140 towards the OZ' side of the third direction ZZ'.

[0084] In this embodiment, the fourth side arm 410 limits the side of the LCD screen 10 away from the third side arm 230. The fourth side arm 410 extends along the second direction YY', meaning it is a relatively long arm structure along the second direction YY', thereby enabling sufficiently reliable limiting of the side of the LCD screen 10 away from the third side arm 230. The limiting member 400 is reliably connected to the fourth support arm 140 by engaging with the elastic locking part 420.

[0085] Please combine Figures 1 to 3 In one embodiment, the limiting member 400 further includes a fifth side arm 430, one end of which is connected to one end of the fourth side arm 410, and the extension direction of the fifth side arm 430 is along the first direction XX'. The fifth side arm 430 is disposed on the outer edge of the first support arm 110 and is spaced apart from the first side arm 210 along the first direction XX'.

[0086] like Figure 1 As shown, a screen cable 11 is provided on one side of the LCD screen 10 along the second direction YY'. The fifth side baffle 430 and the first side baffle 210 are spaced apart along the first direction XX', and the gap between the fifth side baffle 430 and the first side baffle 210 allows the screen cable 11 to pass through.

[0087] When installing the LCD screen 10 onto the mounting bracket, the limiting member 400 is not initially installed on the first mounting frame. During the process of the LCD screen 10, with its screen cable 11, moving into the first mounting frame along the first direction XX', it is not obstructed by the fifth side arm 430, facilitating the arrangement of the screen cable 11. After the LCD screen 10 is in place, the limiting member 400 is then placed on the outer edge of the fourth support arm 140 and engaged with it. At this point, the fifth side arm 430 and the first side arm 210 can jointly limit the LCD screen 10 along one side of the second direction YY'.

[0088] Since the fifth side arm 430 and the first side arm 210 are spaced apart on both sides of the screen line 11, they can both avoid the screen line 11 and limit the position of the LCD screen 10 on both sides of the screen line 11, thus improving the positional reliability of the LCD screen 10.

[0089] Combination Figure 2 , Figure 3 as well as Figure 5 In one embodiment, the elastic snap-fit ​​portion 420 includes a body 421 and a snap-fit ​​connector 422. The body 421 is connected to the fourth side arm 410 at one end along the third direction ZZ', and the other end is connected to the snap-fit ​​connector 422.

[0090] The fourth side arm 410 abuts against the fourth support arm 140 on one side surface along the third direction ZZ', and the snap-fit ​​connector 422 abuts against the fourth support arm 140 on the other side surface along the third direction ZZ'. The main body 421 abuts against the fourth support arm 140 on the side away from the third support arm 130 along the first direction XX'.

[0091] Specifically, the fourth side arm 410 and the snap-fit ​​connector 422 abut against the two sides of the fourth support arm 140 along the third direction ZZ', respectively, thus clamping the fourth support arm 140 along the third direction ZZ'. Simultaneously, the main body 421 abuts against the side of the fourth support arm 140 away from the third support arm 130 along the first direction XX'. This allows the fourth side arm 410, the main body 421, and the snap-fit ​​connector 422 to jointly clamp the fourth support arm 140, achieving a reliable engagement with the fourth support arm 140.

[0092] During actual assembly, an external force is applied to cause the elastic locking part 420 to undergo elastic deformation, so that the locking connector 422 is first located on the side of the fourth support arm 140 away from the third support arm 130. At the same time, the fourth side stop arm 410 is placed on the fourth support arm 140 along the third direction ZZ'. Then the elastic locking part 420 is released, so that the main body 421 abuts against the side of the fourth support arm 140 away from the third support arm 130 along the first direction XX'. At the same time, the locking connector 422 abuts against the side of the fourth support arm 140 opposite to the fourth side stop arm 410. That is, the fourth side stop arm 410, the main body 421, and the locking connector 422 together clamp the fourth support arm 140.

[0093] Conversely, when it is necessary to disassemble the LCD screen 10, an external force is first applied to cause the elastic locking part 420 to undergo elastic deformation, so that the locking part 422 is located on the side of the fourth support arm 140 away from the third support arm 130. This allows the fourth side arm 410 to be removed from the fourth support arm 140 along the third direction ZZ', that is, the limiting member 400 is removed, and then the LCD screen 10 can be pulled out from the side where the fourth support arm 140 is located.

[0094] The material used for the elastic snap-fit ​​part 420 can be plastic or the like. The material used for the limiting part 400 as a whole can be plastic, and the limiting part 400 can be a one-piece molded plastic structure.

[0095] Combination Figure 2 , Figure 3 as well as Figure 5In one embodiment, the fourth support arm 140 has a locking groove 142 on the side away from the third support arm 130 along the first direction XX'. The main body 421 mates with the locking groove 142 and abuts against the bottom of the locking groove 142 along the first direction XX'. In this way, the locking groove 142 positions the main body 421, which facilitates assembly and allows the elastic locking part 420 to engage more reliably with the fourth support arm 140.

[0096] Combination Figure 2 , Figure 3 as well as Figure 5 In one embodiment, the fourth side arm 410 is provided with a plurality of elastic locking portions 420 at intervals along the second direction YY', for example, two or more. This enables a more reliable connection between the limiting member 400 and the fourth support arm 140.

[0097] Please combine Figure 2 and Figure 3 In one embodiment, the fourth support arm 140 is provided with a first positioning hole 141, and the fourth side arm 410 is provided with a first positioning post 411. The first positioning post 411 and the first positioning hole 141 are inserted and engaged in the third direction ZZ'.

[0098] The first positioning pin 411 and the first positioning hole 141 are inserted and engaged along the third direction ZZ', which facilitates the mutual positioning of the fourth side arm 410 and the fourth support arm 140 when assembling the limiting member 400. Furthermore, after the limiting member 400 and the fourth support arm 140 are assembled, the first positioning pin 411 and the first positioning hole 141 can be used for further positioning, ensuring a secure fit between the limiting member 400 and the fourth support arm 140.

[0099] Please combine Figure 2 and Figure 3 In one embodiment, the first support arm 110 is provided with a second positioning hole 111, and the fifth side arm 430 is provided with a second positioning post 431. The second positioning post 431 and the second positioning hole 111 are inserted and engaged in the third direction ZZ'.

[0100] The second positioning pin 431 and the second positioning hole 111 are inserted and engaged along the third direction ZZ', facilitating the mutual positioning of the fifth side stop arm 430 and the first support arm 110 during the assembly of the limiting member 400. Furthermore, after the limiting member 400 and the fourth support arm 140 are assembled, the second positioning pin 431 and the second positioning hole 111 can further position the limiting member 400, ensuring a secure fit between the limiting member 400 and the first support arm 110 and the fourth support arm 140, reducing the risk of displacement and deformation of the fifth side stop arm 430 along the second direction YY'.

[0101] Combination Figure 1 and Figure 2The two ends of the second side arm 220 extend beyond the two ends of the second limit arm 320 along the first direction XX'.

[0102] The first side arm 210 extends beyond the first limit arm 310 at one end near the third support arm 130 along the first direction XX'.

[0103] from Figure 1 As can be seen, the second limiting arm 320 is shorter than the second side stop arm 220. Therefore, the two ends of the second side stop arm 220 extend beyond the two ends of the second limiting arm 320 along the first direction XX'. In this way, when the LCD screen 10 is assembled into the mounting bracket, the two ends of the second limiting arm 320 can be prevented from pressing against the top corner area of ​​the LCD screen 10 along the third direction ZZ', thereby reducing the risk of the top corner area of ​​the LCD screen 10 being crushed.

[0104] from Figure 1 As can be seen, the length of the first limiting arm 310 is shorter than that of the first side stop arm 210. Therefore, the end of the first side stop arm 210 near the third support arm 130 extends beyond the first limiting arm 310 along the first direction XX'. Figure 1 In the embodiment shown, the end of the first side arm 210 near the third support arm 130 is connected to the third side arm 230, while the end of the first limiting arm 310 near the third support arm 130 is spaced from the third side arm 230. This can prevent the first limiting arm 310 from pressing the top corner area of ​​the LCD screen 10 along the third direction ZZ', thereby reducing the risk of the top corner area of ​​the LCD screen 10 being crushed.

[0105] Combination Figure 1 and Figure 2 In one embodiment, the two ends of the third side arm 230 extend beyond the two ends of the third limiting arm 330 along the second direction YY'.

[0106] from Figure 1 and Figure 2 As can be seen, the length of the third limiting arm 330 is shorter than that of the third side stop arm 230. Therefore, the two ends of the third side stop arm 230 extend beyond the two ends of the third limiting arm 330 along the second direction YY'. In this way, when the LCD screen 10 is assembled into the mounting bracket, the two ends of the third limiting arm 330 can be prevented from pressing against the top corner area of ​​the LCD screen 10 along the third direction ZZ', thereby reducing the risk of the top corner area of ​​the LCD screen 10 being crushed.

[0107] Combination Figure 1 and Figure 2 In one embodiment, one end of the first side arm 210 is connected to the third side arm 230, and the length of the first side arm 210 along the first direction XX' is less than half the length of the first support arm 110 along the first direction XX'.

[0108] Since the length of the first side arm 210 along the first direction XX' is less than half the length of the first support arm 110 along the first direction XX', the first side arm 210 only limits the length of the LCD screen 10 along the second direction YY'.

[0109] like Figure 1 As shown, a screen cable 11 is provided on one side of the LCD screen 10 along the second direction YY'. When the LCD screen 10 is installed on the mounting bracket, the limiting member 400 is not installed on the first mounting frame. During the process of the LCD screen 10 with screen cable 11 moving into the first mounting frame along the first direction XX', since the length of the first side arm 210 is relatively short and it is connected to the third side arm 230, it will not block the movement of the screen cable 11 along the first support arm 110, thus facilitating the arrangement of the screen cable 11.

[0110] like Figure 1 As shown, in one embodiment, a notch is provided at the inner corner of the connection between any two adjacent side arms.

[0111] like Figure 1 As shown, a first notch 201 is provided at the inner corner of the connection between the second side arm 220 and the third side arm 230. Thus, when the LCD screen 10 is installed on the mounting bracket, there is a gap between the top corner of the LCD screen 10 and the groove wall of the first notch 201, which avoids collision between the top corner of the LCD screen 10 and the groove wall of the first notch 201. This prevents the top corner of the LCD screen 10 from being damaged by impact with the inner corner of the connection between the second side arm 220 and the third side arm 230.

[0112] like Figure 1 As shown, a second notch 202 is provided at the inner corner of the connection between the first side arm 210 and the third side arm 230. Thus, when the LCD screen 10 is installed on the mounting bracket, there is a gap between the top corner of the LCD screen 10 and the groove wall of the second notch 202, which avoids collision between the top corner of the LCD screen 10 and the groove wall of the second notch 202. This prevents the top corner of the LCD screen 10 from being damaged by impact with the inner corner of the connection between the first side arm 210 and the third side arm 230.

[0113] like Figure 1 As shown, in one embodiment, one end of the fourth side arm 410 abuts against one end of the second side arm 220, and a notch is formed at the inner corner of the abutment between one end of the fourth side arm 410 and one end of the second side arm 220.

[0114] Specifically, the contact point between one end of the fourth side arm 410 and one end of the second side arm 220 forms a corner structure, and the inner corner of the contact point between one end of the fourth side arm 410 and one end of the second side arm 220 forms a third notch 203. Thus, when the LCD screen 10 is mounted on the mounting bracket, there is a gap between the top corner of the LCD screen 10 and the wall of the third notch 203, preventing collision between the top corner of the LCD screen 10 and the wall of the third notch 203. This avoids damage caused by impact between the top corner of the LCD screen 10 and the inner corner of the connection point between the fourth side arm 410 and the second side arm 220.

[0115] like Figure 1 As shown, in one embodiment, a notch is provided at the inner corner of the connection between the fifth side arm 430 and the first side arm 210.

[0116] The inner corner of the connection between the fifth side arm 430 and the first side arm 210 is provided with a fourth notch 401. Thus, when the LCD screen 10 is installed on the mounting bracket, there is a gap between the top corner of the LCD screen 10 and the groove wall of the fourth notch 401, which avoids collision between the top corner of the LCD screen 10 and the groove wall of the fourth notch 401. This prevents the top corner of the LCD screen 10 from being damaged by impact with the inner corner of the connection between the fifth side arm 430 and the first side arm 210.

[0117] like Figure 1 As shown, in one embodiment, the fifth side arm 430 has a slope 432 on the side facing the LCD screen 10 away from the fourth side arm 410.

[0118] That is, the inner side of the end of the fifth side arm 430 away from the fourth side arm 410 has a slope 432, which is inclined outward, that is, in the direction away from the LCD screen 10, so that the LCD screen is not easily damaged.

[0119] Please refer to Figure 4 In one embodiment, the mounting bracket further includes a second mounting frame, which includes four mounting units 500 connected end to end in sequence. The second mounting frame is fixedly connected to the side of the four support arms of the first mounting frame facing away from the side arm.

[0120] Specifically, the second mounting frame can be used to mount the Fresnel lens, and the four edges of the Fresnel lens can be mounted on four mounting units 500 respectively.

[0121] The second mounting frame and the first mounting frame can be a single molded structure. The mounting bracket can be a plastic part, and the second mounting frame and the first mounting frame can be integrally molded using an injection molding process.

[0122] Please refer to Figure 4In one embodiment, the mounting unit 500 includes a mounting arm 510 and a side guard plate 520. The side guard plate 520 is fixedly connected to the outer edge of the mounting arm 510 and protrudes from the mounting arm 510 along the third direction ZZ' towards the side opposite to the support arm.

[0123] At least two opposite side guards 520 have an elastic latch 521 connected to one end away from the corresponding mounting arm 510. The elastic latch 521 protrudes into the inside of the second mounting frame.

[0124] Specifically, the four mounting units 500 are two mounting units 500 arranged parallel to each other along the first direction XX' and two mounting units 500 arranged parallel to each other along the second direction YY'. The mounting units 500 extending along the first direction XX' have their mounting arms 510 and side guard plates 520 extending along the first direction XX'. The mounting units 500 extending along the second direction YY' have their mounting arms 510 and side guard plates 520 extending along the second direction YY'.

[0125] The mounting arms 510 of the four mounting units 500 are used to support the Fresnel lens along the third direction ZZ', and the side guards 520 of the four mounting units 500 are used to laterally limit the Fresnel lens around its perimeter.

[0126] The elastic protrusion 521 is connected to the end of the side guard plate 520 away from the corresponding mounting arm 510, and the elastic protrusion 521 protrudes into the inner side of the corresponding side guard plate 520, so that the elastic protrusion 521 can press the Fresnel lens along the third direction ZZ', thereby fixing the Fresnel lens in the second mounting frame.

[0127] Optionally, elastic locking protrusions 521 are connected to the two side guards 520 opposite each other along the second direction YY', thereby enabling more reliable fixation of the lens.

[0128] Please refer to Figure 1 One embodiment of this application provides a display module, including a liquid crystal display (LCD) screen 10 and a mounting bracket of any of the above embodiments, wherein the LCD screen 10 is mounted on the mounting bracket.

[0129] One embodiment of this application provides a projector including the above-described display module.

[0130] In the aforementioned display module and projector, when the mounting bracket is used to mount the LCD screen 10 of the projector, the LCD screen 10 is moved from one end of the mounting bracket with the fourth support arm 140 along the first direction XX' into the first mounting frame until the four edges of the LCD screen 10 overlap the four support arms respectively. Then, the limiting member 400 is set on the outer edge of the fourth support arm 140 and engages with the fourth support arm 140. During the installation process, the LCD screen 10 can be protected from significant external pressure, thereby improving the safety of the installation process and reducing the risk of damage to the LCD screen 10. After the LCD screen 10 is installed in the mounting bracket, the side stops and limiting members 400 on the outer edges of the first support arm 110, the second support arm 120, and the third support arm 130 can respectively limit the lateral movement of the LCD screen 10. The limiting arms and support arms can limit the LCD screen 10 on both sides along the third direction ZZ', thus achieving six-sided limiting of the LCD screen 10, and fully and reliably realizing the installation and positioning of the LCD screen 10.

[0131] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
