Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display frame and a display. Background Technology

[0002] In LCD displays, the outer frame typically consists of a front frame and a back panel, with an internal middle frame. The front frame and back panel are fixedly assembled, usually by snapping them together with side clips. However, due to manufacturing errors, there may be some dimensional deviations between the front frame and back panel. These dimensional deviations can lead to gaps between the front frame and back panel during assembly, causing them to loosen. This is especially true in automotive displays. If the gap between the front frame and back panel is too large, it can cause impact noises during the snap-fit ​​process, resulting in the backlight module inside the outer frame shaking and causing internal components to malfunction and make impact noises.

[0005] The back plate includes a bottom plate and a side plate located on the side of the bottom plate and extending toward one side of the bottom plate. The inner surface of the bottom plate is opposite to the inner surface of the front edge, and the side plate is disposed opposite to the side wall of the frame structure. The side plate has a second snap-fit ​​portion for engaging with the first snap-fit ​​portion. When the first snap-fit ​​portion engages with the second snap-fit ​​portion, the second snap-fit ​​portion is located on the side of the first snap-fit ​​portion facing the front edge.

[0006] The middle frame is located inside the front frame, and the elastic pad is located between the top surface of the side wall of the middle frame facing the front edge and the front edge. The elastic pad is used to support the top surface of the side wall of the middle frame and the front edge so that the first snap-fit ​​part and the second snap-fit ​​part are snapped together.

[0007] In the aforementioned monitor frame, an elastic pad is set between the middle frame and the front edge to increase the support thickness between the front edge and the bottom plate, eliminate the fit gap between the back plate and the front frame, play a foolproof role, and make the back plate and the front frame lock together, effectively avoiding impact noise between the back plate and the front frame, and preventing abnormal noise caused by the shaking of internal components of the monitor frame.

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0031] like Figure 1 and Figure 2As shown, this embodiment of the present disclosure provides a display frame, which includes a front frame 1, a back panel 2, a middle frame 3, and an elastic pad 4. The front frame 1 includes a frame structure and a front edge 12. The frame structure is a frame-shaped structure surrounded by side walls. Specifically, the shape of the frame structure can be a rectangle, that is, the frame structure is a rectangular frame. For ease of explanation, in this embodiment, the side wall of the frame structure is referred to as the first side wall 11. The front edge 12 is located at one end of the frame structure and extends towards the center of the frame structure. The front edge 12 is connected to one end of the first side wall 11 and extends towards the center of the frame structure. Each end of the first side wall 11 can be connected to the front edge 12, and the front edge 12 is perpendicular to the first side wall 11. In addition, in the frame structure... The first sidewalls 11 of the frame structure have a first latching portion 111; specifically, the first latching portion 111 can be provided only on the sides of a pair of opposing first sidewalls 11 of the frame structure, or the first latching portion 111 can be provided on each of the first sidewalls 11 of the frame structure; the back plate is provided with a second latching portion 221 that latches with the first latching portion 111 to achieve a latching connection. Specifically, the back plate 2 includes a bottom plate 21 and a side plate 22. The side plate 22 is provided along the side edge of the bottom plate 21 and extends toward one side of the bottom plate 21. The side plate 22 is perpendicular to the bottom plate 21. The bottom plate 21 is opposite to the front edge 12 of the front frame. The side plate 22 is opposite to the first sidewall 11. The second latching portion 221 is provided on one side of the side plate 22 and cooperates with the first latching portion 111. When the first latching portion 111 is engaged, the second latching portion 221 engages with the first latching portion 111. When the first snap-fit ​​part 111 engages with the second snap-fit ​​part 221, the second snap-fit ​​part 221 is located on the side of the first snap-fit ​​part 111 facing the front edge 12. The middle frame is set inside the front frame. In the direction perpendicular to the bottom plate 21, the side wall of the middle frame 3 can be supported between the back plate and the front edge 12. For ease of explanation, the side wall of the middle frame 3 is referred to as the second side wall 31. The second side wall 31 can be supported between the back plate and the front edge 12, so that the first snap-fit ​​part 111 and the second snap-fit ​​part 221 engage. To avoid any gap between the first snap-fit ​​part 111 and the second snap-fit ​​part 221, an elastic pad 4 is provided on the side wall of the middle frame facing the front edge 12. The elastic pad 4 is between the second side wall 31 and the front edge 12, and plays a supporting and anti-misalignment role. When manufacturing deviations cause... When there is a gap between the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221, the supporting thickness of the elastic pad 4 can offset the gap between the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221, making the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221 fit tightly. Even if the manufacturing deviation is very small or nonexistent, there is no gap between the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221. The elastic pad 4 has a certain elasticity. When the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221 are engaged, the elastic pad is compressed and the thickness decreases, which will not affect the fit between the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221. This allows the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221 to achieve an interference fit through slight deformation of the structure, resulting in a tighter fit.

[0032] Therefore, in the above-mentioned display frame, an elastic pad is set between the middle frame and the front edge 12 to increase the support thickness between the front edge 12 and the bottom plate 21, eliminate the fit gap between the back plate and the front frame, play a foolproof role, and make the back plate and the front frame clamp together, effectively avoiding impact noise between the back plate and the front frame, and avoiding abnormal noise caused by the shaking of internal components of the display frame.

[0033] In one possible implementation, the aforementioned middle frame is a rubber frame, and the elastic pad can be a flexible rubber pad, specifically a silicone pad or other elastic rubber pad; this embodiment is not limited to this.

[0034] In one possible implementation, the side plate 22 is located inside the side wall of the frame structure, for example, as shown in... Figure 2 As shown, the side plate 22 is opposite to the first side wall 11, and the first side wall 11 is fitted on the outside of the side plate 22. A slot is provided on the first side wall 11. A bent arm is connected to the side of the slot away from the front edge 12 and bends inward to form a bent arm. The bent arm constitutes the first snap-fit ​​part 111. The first snap-fit ​​part 111 has a first overlapping surface on the side facing the front edge 12. The side plate 22 is inside the first side wall 11. There is a gap between the top surface of the side plate 22 facing the front edge 12 and the front edge 12. The middle frame can be placed on the top surface of the side plate 22 and is located between the front edge 12 and the top surface of the side plate 22. The second side wall 31 of the middle frame has an extension part 32 extending to the space between the first side wall 11 and the side plate 22 on the side facing the bottom plate 21, so that the first side wall 11 and the side plate 22 fit tightly in the direction parallel to the bottom plate 21 and avoid shaking. The side panel 22 has an outwardly protruding protrusion forming a second snap-fit ​​portion 221. The side of the second snap-fit ​​portion 221 facing the bottom plate 21 has a second overlapping surface, which can snap-fit ​​with the first overlapping surface. Specifically, the extension portion 32 has a through groove at the corresponding part of the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221, so that the first snap-fit ​​portion 111 and the second snap-fit ​​portion 221 can pass through and snap-fit ​​on both sides of the extension. For example, the first overlapping surface and the second overlapping surface can both be arranged parallel to the front edge 12, which facilitates the assembly of the back panel and the front frame and ensures a firm snap-fit. The elastic pad is between the second side wall 31 and the front edge 12. The support thickness of the elastic pad is in the same direction as the fit gap between the first overlapping surface and the second overlapping surface, which can be directly compared with the fit gap, making it convenient to install the elastic pad.

[0035] like Figure 1As shown, in the direction perpendicular to the bottom plate 21 of the back panel, and for ease of explanation, the direction perpendicular to the bottom plate 21 of the back panel is taken as the Z direction. In the Z direction, the distance from the second overlapping surface of the second latching part 221 to the inner surface of the front edge 12 is X, and the distance from the first overlapping surface of the first latching part 111 to the outer surface of the front edge 12 is Y. Considering the manufacturing capabilities of the back panel and the front frame, the recommended manufacturing accuracy is: the distance accuracy from the second overlapping surface of the second latching part 221 to the inner surface of the front edge 12 is X ± 0.1 mm, and the distance accuracy from the first overlapping surface of the first latching part 111 to the outer surface of the front edge 12 is Y ± 0.1 mm. Define the thickness of the front edge 12 as T, then the engagement gap between the back panel and the front frame (i.e., the fitting gap between the first latching part 111 and the second latching part 221) D = Y × T. Due to dimensional deviations during manufacturing, the engagement gap between the back panel and the front frame will have the following two extreme cases:

[0036] Scenario 1: When the precision of Y is taken as the lower limit of the dimension, and the precision of X is taken as the lower limit of the dimension, the following applies:

[0037] The limit of the interlocking gap between the back panel and the front frame, D' = (Y-0.1)-(X+0.1)-T, needs to satisfy D'≥0, i.e., D = YXT≥0.2mm. In reality, not every interlocking structure between the back panel and the front frame will be at the limit size. When the interlocking structure between the back panel and the front frame is at the limit size of case one, the back panel and the front frame can achieve an interference fit through slight deformation of the structure, thereby achieving a tight interlocking effect. Therefore, preferably, D = 0.1mm can be selected as the standard for the size of the interlocking structure between the back panel and the front frame, which can ensure that the back panel and the front frame fit normally and make the front frame and the back panel fit tightly, achieving a gapless fit.

[0038] Scenario 2: When the precision of Y is taken as the upper limit of the dimension, and the precision of X is taken as the lower limit of the dimension, as follows:

[0039] The maximum engagement gap between the back panel and the front frame is D'' = (Y + 0.1) - (X - 0.1) - T = YX - T + 0.2. Based on the above situation one, the preferred standard for size design is D = 0.1 mm. Then D'' = 0.3 mm. There will be an engagement gap between the back panel and the front frame, which makes there a risk of impact noise between the front frame and the back panel. Moreover, this maximum engagement gap D'' = 0.3 mm is generated under the actual manufacturing capabilities and is unavoidable.

[0040] Based on the structure of the display frame described above, there are several possible configuration options for the elastic pad on the top surface of the second sidewall. Specifically, in one possible implementation, such as... Figure 3 and Figure 4As shown, a groove 311 is provided on the top surface of the second sidewall 31, and an elastic pad is located within the groove 311, with the thickness of the elastic pad being greater than the depth of the groove 311. This allows for a seamless fit when a situation similar to Case 1 occurs, where there is no gap between the back panel and the front frame, and the structure itself can fit without gaps. During assembly, the elastic pad is completely compressed into the groove 311, ensuring a tight fit between the back panel and the front frame. If a situation similar to Case 2 occurs, where there is a gap between the back panel and the front frame, the elastic pad provides support, offsetting the gap and ensuring a tight fit between the back panel and the front frame. This is very convenient to use, has a simple structure, and allows for a good fit between the back panel and the front frame. Furthermore, the groove 311 provides a certain degree of restraint for the elastic pad, allowing it to be properly installed on the top surface of the second sidewall 31.

[0041] Furthermore, the elastic pad can be adhered to the bottom of the groove with double-sided adhesive, making the connection simple and secure.

[0042] In addition, to ensure a better interlocking between the back panel and the front frame, the thickness of the elastic pad and the depth of the groove should satisfy the following relationship:

[0043]

[0044] Where f is the depth of groove 311, D is the mating clearance between the first snap-fit ​​part and the second snap-fit ​​part, d is the thickness of the elastic pad, and n is the compression ratio of the elastic pad.

[0045] Preferably, the elastic pad is a silicone pad with a compression ratio of up to 50%. Based on the two extreme cases described in Case 1 and Case 2, the maximum clearance between the first and second overlapping surfaces can reach 0.3 mm. Therefore, the preferred depth of the groove 311 is 0.4 mm, meaning 0.7 mm < d ≤ 0.8 mm. Preferably, d can be 0.75 mm to 0.8 mm. Specifically, the depth of the groove 311 can be 0.38 mm. Any value within ~0.42 mm, such as 0.39 mm, 0.41 mm, or other values, is not limited in this embodiment. The thickness of the silicone pad can be 0.76 mm, 0.77 mm, or other values, which is not limited in this embodiment. For example, a silicone pad with a thickness of 0.78 mm can be designed and assembled in a 0.4 mm groove 311, which can achieve a gapless engagement between the back panel and the front frame, ensuring a tight assembly and preventing loosening that could cause abnormal noise or other problems.

[0046] Due to the material properties of the silicone pad, the minimum cutting width is 1 mm. There is a deviation when attaching the silicone pad, with a deviation of approximately 0.2 mm on each side. Considering the 1 mm cutting width of the silicone pad, a 0.2 mm assembly tolerance is allowed on each side, and a 0.3 mm manufacturing tolerance is allowed on both sides of the groove 311, the width of the second sidewall 31 of the middle frame can be set to be greater than 2 mm. Therefore, for the dimensional design of the silicone pad and the groove 311, where the length is the dimension along the extension direction of the first sidewall 11 and the width is the dimension along the width direction of the first sidewall 11, the length L1 and width W1 of the groove, and the length L2 and width W2 of the silicone pad, have the following relationships corresponding to different widths of the second sidewall:

[0047] When the width of the second sidewall is ≥3mm, the design dimensions of the groove 311 are: length L1 and width W1; the dimensions of the silicone pad are: length L2 and width W2.

[0048] When 2 mm ≤ width of the second sidewall < 3 mm, the design dimensions of the groove 311 are: length L1 and width W1-0.6; the dimensions of the silicone pad are: length L2 and width W2-0.4.

[0049] Regarding the design of the silicone pad in the groove, the lengths of both the groove and the silicone pad can be selected to be appropriate. Following the variation in the width of the second sidewall, the widths of the groove and the silicone pad can be set using the above formula. Preferably, for example:

[0050] When the width of the second sidewall 31 is ≥3 mm, the design dimensions of the groove 311 are: length 8.4 mm and width 2.4 mm, and the dimensions of the silicone pad are: length 8 mm and width 2 mm; when 2 mm ≤ the width of the second sidewall 31 is <3 mm, the design dimensions of the groove 311 are: length 8.4 mm and width 1.8 mm, and the dimensions of the silicone pad are: length 8 mm and width 1.6 mm. Alternatively, other dimensions may be designed, and this embodiment is not limited to these dimensions.

[0051] In another possible implementation, such as Figure 5As shown, a boss 312 is provided on the top surface of the second sidewall 31. The boss can be integral with the second sidewall, directly machined from its top surface, or it can be a separate structure from the second sidewall. An elastic pad is located around the boss 312, and the thickness of the elastic pad 4 is greater than the height of the boss 312. In situations similar to Case 1, where there is no gap between the back panel and the front frame, the structure can fit together without gaps. During assembly, the elastic pad is compressed, and its thickness matches the height of the boss, ensuring a tight fit between the back panel and the front frame. In Case 2, where there is a gap between the back panel and the front frame, the thickness of the elastic pad, greater than the height of the boss, provides support, offsetting the gap and ensuring a tight fit between the back panel and the front frame. This design is convenient, simple, and allows for a good fit between the back panel and the front frame. Furthermore, the elastic pad can be adhered to the top surface of the second sidewall 31 with double-sided adhesive, ensuring a secure connection. Specifically, the elastic pad can be placed on one side of the protrusion or can be arranged around the protrusion; this embodiment is not limited to this.

[0052] Furthermore, to ensure better engagement between the back panel and the front frame, the thickness of the elastic pad and the height of the boss 312 are made to satisfy the following relationship:

[0053]

[0054] Where e is the height of the boss 312, D is the mating clearance between the first snap-fit ​​part and the second snap-fit ​​part, d is the thickness of the elastic pad, and n is the compression ratio of the elastic pad.

[0055] Preferably, the elastic pad is a silicone pad with a compression ratio of up to 50%. Given the extreme cases of Case 1 and Case 2, the maximum clearance between the first and second overlapping surfaces can reach 0.3 mm. Therefore, the height of the boss 312 can preferably be 0.4 mm, resulting in 0.7 mm < d ≤ 0.8 mm. Preferably, d can be 0.75 mm to 0.8 mm. Specifically, the height of the boss 312 can be 0.38 mm to 0. Any value within 42mm, such as 0.39mm, 0.41mm, or other values, is not limited in this embodiment. The thickness of the silicone pad can be 0.76mm, 0.77mm, or other values, which is also not limited in this embodiment. For example, a silicone pad with a thickness of 0.78mm can be designed and assembled on the periphery of the 0.4mm high boss 312, which can achieve a gapless engagement between the back panel and the front frame, ensuring a tight assembly and preventing loosening that could cause abnormal noise or other problems.

[0056] Since the silicone pad is directly set on the periphery of the boss 312, and the width of the boss 312 is smaller than the width of the first sidewall 11, the silicone pad can be set at the second sidewall 31 since the width of the silicone pad is smaller than the width of the second sidewall 31. Therefore, it can be adapted to the design of the second sidewall 31 with a relatively narrow width. For example, when the width of the second sidewall 31 is less than or equal to 2 mm, the boss 312 can be set on the top surface of the second sidewall 31 to cooperate with the silicone pad, so that the back panel and the front frame can be well connected. It should be noted that for the second sidewall with a relatively wide width, such as the second sidewall with a width greater than 2 mm, a boss can also be formed on the top surface of the second sidewall to cooperate with the elastic pad. The setting of the boss on the top surface of the second sidewall is not limited to the case where the width of the second sidewall is less than or equal to 2 mm.

[0057] In one possible implementation, the silicone pad has a hardness of 50 degrees, which can provide good support and make the back panel and front frame fit together tightly.

[0058] Based on any of the above display frames, such as Figure 2 As shown, an elastic pad is provided on the top surface of the side wall opposite to the first snap-fit ​​portion in the middle frame, so that the elastic pad is correspondingly provided with the side wall in the frame structure where the first snap-fit ​​portion 111 is provided. Specifically, along the extension direction of the corresponding first side wall 11, the position of the elastic pad is opposite to the first snap-fit ​​portion 111, so that the elastic pad is provided corresponding to the first snap-fit ​​portion 111. That is, the elastic pad is provided correspondingly at the part where the back panel and the front frame have a snap-fit ​​structure, which can better eliminate the fitting gap and make the back panel and the front frame snap tightly together. Preferably, combined with Figure 1 ,like Figure 6 As shown, when the frame structure is a rectangular frame, a first snap-fit ​​part can be set on one side of the short side, and an elastic pad can be set accordingly to facilitate assembly.

[0059] Furthermore, along the extension direction of one sidewall of the middle frame where the elastic pad is provided, at least two elastic pads are provided, and the at least two elastic pads are arranged alternately. This provides stable support between the middle frame and the front edge 12, ensuring stable assembly between the back panel and the front frame.

[0060] Based on any of the above-mentioned display frames, protrusions protruding towards the inside of the middle frame are provided on two opposite side walls of the middle frame. The protrusions can be used to snap onto the glass substrate mounted on the middle frame, so that the glass substrate is stably mounted on the middle frame. An elastic pad is provided on the top surface of the part of the side wall of the middle frame with the protrusion. Specifically, a protrusion can be provided on the inner side of each second side wall, which can better support the substrate glass and improve stability. On the other hand, providing a protrusion on the inner side of the second side wall, compared with the above-mentioned groove and silicone pad structure, allows the groove to be provided at the part of the second side wall with the protrusion, which facilitates the processing of the groove. More specifically, when 2 mm ≤ width of the second side wall < 3 mm, the groove can be provided at the part of the second side wall with the protrusion, so that the sum of the width of the second side wall and the protrusion width can meet the groove processing size requirements.

[0061] More specifically, for the second sidewall with protrusions, at least two protrusions can be provided along the extending direction of the second sidewall. Providing at least two spaced protrusions on the inner side of the same second sidewall can more evenly support the glass substrate, making the glass substrate more stable. On the other hand, it allows for more layout options for the elastic pads, making the layout of the elastic pads more convenient.

[0062] This disclosure also provides a display, including any of the display frames provided in the above embodiments, a display panel mounted on the middle frame, and a backlight module mounted in the back panel, wherein the backlight module is located between the display panel and the bottom plate of the back panel.

[0063] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this disclosure without departing from the spirit and scope of this disclosure. Therefore, if these modifications and variations of this disclosure fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include these modifications and variations.
