Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a frame assembly and a display device. Background Art

[0002] When the upper and left and right frames of the frame assembly can share a common cross-section, a long frame is usually first rolled out, and then a V-shaped notch is made at the corner position and then folded 90 degrees to form upper and left U-shaped frames, which are then spliced ​​with the lower frame to form a four-sided integrated frame.

[0003] However, the U-frame formed on the upper left and right sides is welded and polished at the joint gap after being bent, and the U-frame and the lower frame are also welded and polished after being spliced. This welding and polishing process is prone to cause surface defects, such as damage to the R angle of the outer shape and concave surface due to uneven polishing, which also causes cost increases. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present application provides a frame assembly on the one hand, which comprises at least a first frame, a second frame and a corner connector, wherein the first frame comprises a first frame body and a first overlapping portion, and the first overlapping portion is located at an end of the first frame body; the second frame comprises a second frame body and a first corner portion, and the first corner portion is located at one end of the second frame body, the first corner portion is bent toward the first frame body and spliced ​​with the end of the first frame body, and the first overlapping portion is overlapped on the front side of the first corner portion; the corner connector is located in the corner area formed by the first frame and the second frame, and the corner connector comprises a first part and a second part connected to each other, the first part is connected to the first frame, and the second part is connected to the second frame.

[0006] The technical solution provided by the present application arranges the first overlapping portion on the front side of the first corner portion to cover the splicing gap or notch on the front side of the first corner portion, so that there is no need to set a bending splicing at the first corner portion due to aesthetic issues, that is, there is no splicing gap, or, after the bending splicing is set at the first corner portion, there is no need to weld and polish the splicing gap at the first corner portion, thereby eliminating the need for welding and polishing and other processes that may cause poor processing, avoiding production waste, reducing production costs, and improving product quality, thereby ensuring aesthetics while reducing the processing steps for the bending gap at the corner to reduce production costs.

[0007] Furthermore, the first frame and the second frame are connected by a corner connector to ensure their assembly stability. At the same time, the first overlap portion is overlapped on the front side of the first corner portion, which can also play a role in pre-positioning the assembly of the first frame and the second frame, thereby facilitating the connection of the corner connector with the first frame and the second frame.

[0017] Through the above scheme, the splicing method of the third frame and the second frame also does not require welding and grinding of the splicing gap at the second corner, thereby eliminating the need for welding and grinding and other processes that may cause poor processing, avoiding production waste, reducing production costs, and improving product quality. This ensures aesthetics while reducing the processing steps for the bending gaps at the corners to reduce production costs.

In addition, the front side of the third overlap portion is flush with the front side of the second frame body, which can prevent the third overlap portion from protruding from the second frame body, so that the front side of the frame assembly is a flat plane to ensure aesthetics.

[0057] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship between a unit or feature as shown in the accompanying drawings relative to another unit or feature for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptors used herein are interpreted accordingly.

[0058] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0059] In the design of infrared touch all-in-one machines, the frame assembly plays a vital role. It is usually used as the edge support structure of the whole machine. At present, the frame is mostly made of aluminum profiles through extrusion molding. This method is popular because of its light material and stable structure. However, in order to effectively reduce costs, some manufacturers have begun to turn to galvanized steel sheets as raw materials to manufacture frames through sheet metal processing or rolling processes. During the production process, when the cross-sections of the upper, left and right frames are designed to be shared, the galvanized steel sheets are first formed into the required long strips through a rolling process. Then, some necessary holes and notches are punched out through a stamping process, and then a V-shaped notch is made at the predetermined corner position, and then precisely bent to 90 degrees to form a U-shaped frame. These U-shaped frames are then precisely spliced ​​with the lower frame to form a neat four-sided integrated frame.

[0060] Although this process is continuous and efficient in production, traditional welding and grinding techniques may bring some challenges in processing the joint gap after the U-shaped frame is bent. Welding and grinding processes may cause surface defects, such as damage to the R corner, uneven surface or concave depression, which not only affects the appearance quality of the product, but also increases production costs.

[0061] In addition, the packaging and transportation of the four frames after they are spliced ​​together also leads to increased transportation costs due to the large area they occupy.

[0062] To this end, the present application splits the frame assembly into four frames that are spliced ​​together, thus avoiding the problem of high integrated transportation costs. At the same time, one of the two frames that are spliced ​​together is provided with a first overlap portion, and the other is provided with a first corner portion, and the first overlap portion is arranged on the front side of the first corner portion to form a corner structure together. In other words, the first overlap portion shields the front side of the first corner portion, so that there is no need to set a bending splicing at the first corner portion, or the splicing gap after the bending splicing at the first corner portion does not need welding and grinding, thereby eliminating the need for welding and grinding processes after bending, avoiding welding, grinding and other processes that may cause poor processing, avoiding production waste, and thus reducing production costs and improving product quality. In addition, a corner connector is also provided at the corner to connect the two frames that are spliced ​​together to ensure their assembly stability.

[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0064] The present application provides a frame assembly, which is mainly used in display devices (such as display screens, interactive tablets, etc.). The frame assembly is used to enclose and form a housing space for the installation of glass panels, display components, glass brackets and other components, and to provide support and protection for the components in the housing space. Among them, when the display device is an interactive tablet, the frame assembly can be a hollow structure, and a filter strip and a touch circuit board are installed inside the frame assembly to realize the touch interaction function.

[0065] For details, please refer to Figure 1 to Figure 2 ,as well as Figures 3 to 5 As shown, in an achievable implementation, the frame assembly may include a first frame 100 and a second frame 200. The first frame 100 may include a first frame body 110 and a first overlap portion 120, and the first overlap portion 120 is located at the end of the first frame body 110. In practical applications, the first frame body 110 and the first overlap portion 120 may be designed as an integral whole, which may be manufactured by sheet metal processing or rolling process.

[0066] The second frame 200 is adjacent to and spliced ​​with the first frame 100. Specifically, the second frame 200 may include a second frame body 210 and a first corner portion 220, the first corner portion 220 is located at one end of the second frame body 210, the first corner portion 220 is bent toward the first frame body 110 and spliced ​​with the end of the first frame body 110, and the first overlap portion 120 is provided at the front side of the first corner portion 220.

[0067] In practical applications, the second frame 210 and the first corner portion 220 are designed as an integral unit, which can be manufactured by sheet metal processing or rolling process. During the bending process of the first corner portion 220, a V-shaped notch or a complete notch is required at the bending position thereof, so that the first corner portion 220 can be bent toward the first frame 110. When a V-shaped notch is performed at the bending position of the first corner portion 220, there will inevitably be a splicing gap after bending, and when the bending position is completely notched, there will be no splicing gap but a notch after bending.

[0068] To this end, the present application arranges the first overlapping portion 120 on the front side of the first corner portion 220 to cover the splicing gap or notch on the front side of the first corner portion 220, so that there is no need to set a bending splicing at the first corner portion 220 due to aesthetic issues, that is, there is no splicing gap, or, after the bending splicing is set at the first corner portion 220, there is no need to weld and polish the splicing gap at the first corner portion 220, thereby eliminating the need for welding and polishing and other processes that may result in poor processing, thereby avoiding production waste, reducing production costs, and improving product quality, thereby ensuring aesthetics while reducing the processing steps for the bending gaps at the corners to reduce production costs.

[0069] In an achievable implementation, the frame assembly may further include a corner connector 300. The corner connector 300 is located in the corner region formed by the first frame 100 and the second frame 200. The corner connector 300 includes a first portion 310 and a second portion 320 connected to each other, the first portion 310 is connected to the first frame 100, and the second portion 320 is connected to the second frame 200. In this way, the first frame 100 and the second frame 200 are connected by the corner connector 300 to ensure their assembly stability.

[0070] In practical applications, the first part 310 is connected to the first frame 110 of the first frame 100, and the first frame 110 bears the connection force to ensure the connection stability. The second part 320 can be connected to the second frame 210, or it can be connected to the first corner portion 220. Preferably, the second part 320 is connected to the second frame 210, so as to ensure the connection stability by utilizing the high strength of the second frame 210. At the same time, it can be understood that the first lap portion 120 is arranged on the front side of the first corner portion 220, and it can also play a role in pre-positioning the assembly of the first frame 100 and the second frame 200, thereby facilitating the connection of the corner connector 300 with the first frame 100 and the second frame 200.

[0071] It should be noted that, in the present application, for each component in the frame assembly, the side close to the center of the frame assembly is the inner side of each component, and the side away from the center of the frame assembly is the outer side of each component. When the frame assembly is applied to a display device, when the display device is in use by a user, the side facing the user is the front side of each component, that is, the "front" direction indicated by the arrow in the accompanying drawings, and the side away from the user is the rear side of each component, that is, the "rear" direction indicated by the arrow in the accompanying drawings.

[0072] Regarding the manner in which the first overlapping portion 120 is disposed on the front side of the first corner portion 220 , the present application provides two achievable embodiments for reference.

[0073] In the case where there is a gap in front of the bending position of the first corner portion 220 that can completely accommodate the first overlapping portion 120, such as Fig.10 and Fig.14 As shown, in an achievable implementation, the front side of the second frame 200 is provided with a first overlap notch 221 matching the first overlap portion 120, or in other words, a gap for avoidance provided by the bend. The first overlap portion 120 is embedded in the first overlap notch 221, and the first overlap portion 120 fills the first overlap notch 221, thereby covering the first overlap notch 221 to ensure the integrity of the appearance of the frame assembly.

[0074] Further, such as Fig.10 As shown, the front side of the first overlapping portion 120 is flush with the front side of the second frame 210, so that the first overlapping portion 120 can be prevented from protruding from the second frame 210, so that the front side of the frame assembly is a flat plane to ensure aesthetics.

[0075] Further, such as Fig. 9 and Fig.10 As shown, the first overlap portion 120 can extend to the outer edge of the second frame 200, and the inner edge of the front side of the first overlap portion 120 and the inner edge of the front side of the first frame body 110 are located on the same straight line. Fig. 9 From the front perspective shown, the front side of the first frame 100 can extend to the left and right ends of the frame assembly to form a through visual effect, thereby making the display device using the frame assembly more beautiful as a whole.

[0076] For the situation where there is a splicing gap in front of the bending position of the first corner portion 220 or the gap of the first overlapping portion 120 cannot be completely accommodated, such as Figure 2 and Figure 6 As shown, in an achievable implementation, the first overlapping portion 120 overlaps the front side of the first corner portion 220, the front side of the first overlapping portion 120 is staggered with the front side of the first corner portion 220, and the first overlapping portion 120 blocks the front side of the first corner portion 220. In this way, the first overlapping portion 120 can block the splicing gap of the first corner portion 220 at the front side or the gap that cannot completely accommodate the first overlapping portion 120, so as to ensure the integrity of the appearance of the frame assembly.

[0077] Further, such as Figure 1 and Figure 2 As shown, the first overlap portion 120 can extend to the outer edge of the second frame 200, and the inner edge of the front side of the first overlap portion 120 and the inner edge of the front side of the first frame body 110 are located on the same straight line. Figure 1From the front perspective shown, the front side of the first frame 100 can extend to the left and right ends of the frame assembly to form a through visual effect, thereby making the display device using the frame assembly more beautiful as a whole.

[0078] In order to further improve the connection stability between the first frame 100 and the second frame 200, please refer to Figure 6 As shown, in a feasible implementation, a second overlapping portion 222 is provided at one end where the first corner portion 220 is spliced ​​with the first frame body 110 . The second overlapping portion 222 extends toward the first frame body 110 into the first frame body 110 and is connected to the first frame body 110 .

[0079] In practical applications, the second overlap portion 222 may be recessed inward from the outer side of the first corner portion 220, so that when splicing, the second overlap portion 222 can be inserted into the hollow cavity formed by the first frame body 110. The first frame body 110 may be locked and connected to the second overlap portion 222 by screws passing through the outer side of the first frame body 110. Of course, other connection methods may also be used, such as clamping, welding, riveting, etc.

[0080] like Figures 4 to 6 , Figure 12 to Figure 14 As shown, in an achievable embodiment, the first frame 110 has a first folded edge 111 extending inwardly, and the first portion 310 is located at the front side of the first folded edge 111 and connected to the first folded edge 111. The second frame 210 has a second folded edge 211 extending inwardly, and the second portion 320 is located at the front side of the second folded edge 211 and connected to the second folded edge 211. In other words, the corner connector 300 is connected to the inwardly extending portion of the first frame 100 and the second frame 200, so that the formation of a connection area on the outer surface of the first frame 100 and the second frame 200 can be avoided, thereby ensuring the overall aesthetics of the frame assembly.

[0081] In practical applications, the first folded edge 111 can be screwed through the first folded edge 111 and locked with the first part 310, and the second folded edge 211 can be screwed through the second folded edge 211 and locked with the second part 320. Of course, other connection methods can also be used, and this application does not specifically limit this.

[0082] like Figure 1 and Figure 3 , as shown, in an achievable implementation, the frame assembly may further include a third frame 400. The first frame 100 may be used as an upper frame, and accordingly, the third frame 400 disposed opposite to the first frame 100 is used as a lower frame, and the second frame 200 adjacent to the first frame 100 is a side frame. Of course, the first frame 100 may also be used as a lower frame or a side frame, and this application does not specifically limit this.

[0083] In this embodiment, the third frame 400 includes a third frame body 410 and a third overlap portion 420, and the third overlap portion 420 is located at the end of the third frame body 410. In practical applications, the third frame body 410 and the third overlap portion 420 can be designed as an integral whole, for example, they can be manufactured by sheet metal processing or rolling process.

[0084] The second frame 200 is adjacent to and connected to the third frame 400. Specifically, the second frame 200 further includes a second corner portion 230, which is located at the other end of the second frame body 210, the second corner portion 230 is bent toward the third frame 400 and connected to the end of the third frame 400, and the third overlap portion 420 is overlapped on the front side of the second corner portion 230.

[0085] In practical applications, the second frame 200 and the second corner portion 230 are designed as one piece, which can be manufactured by sheet metal processing or rolling process. In the process of bending the second corner portion 230, a V-shaped notch or a complete notch is required at the bending position thereof, so that the second corner portion 230 can be bent toward the third frame body 410. When a V-shaped notch is performed at the bending position of the second corner portion 230, there will inevitably be a splicing gap after bending, and when the bending position is completely notched, there will be no splicing gap but a notch after bending.

[0086] To this end, the present application arranges the third overlap portion 420 on the front side of the second corner portion 230 to cover the splicing gap or notch on the front side of the second corner portion 230, so that there is no need to set a bending splicing at the second corner portion 230 due to aesthetic issues, that is, there is no splicing gap, or, after the bending splicing is set at the second corner portion 230, there is no need to weld and polish the splicing gap at the second corner portion 230, so that there is no need for welding and polishing steps, avoiding welding, polishing and other processes that may cause poor processing, avoiding production waste, reducing production costs, and improving product quality, thereby achieving the goal of reducing the processing steps of the bending gaps at the corners while ensuring aesthetics, thereby reducing production costs.

[0087] Regarding the manner in which the third overlapping portion 420 is disposed on the front side of the second corner portion 230 , the present application provides two achievable embodiments for reference.

[0088] In the case where there is a gap in front of the bending position of the second corner portion 230 that can completely accommodate the third overlapping portion 420, such as Fig.11 and Fig.16As shown, in an achievable implementation, the front side of the second frame 200 is provided with a second overlapping notch 231 matching the third overlapping portion 420, or in other words, a gap for avoidance provided by the bend. The third overlapping portion 420 is embedded in the second overlapping notch 231, and the third overlapping portion 420 fills the second overlapping notch 231, thereby covering the second overlapping notch 231 to ensure the integrity of the appearance of the frame assembly.

[0089] Further, such as Fig.11 As shown, the front side of the third overlapping portion 420 is flush with the front side of the second frame 210, so that the third overlapping portion 420 can be prevented from protruding from the second frame 210, so that the front side of the frame assembly forms a flat plane to ensure aesthetics.

[0090] Further, such as Fig. 9 and Fig.11 As shown, the third overlap portion 420 can extend to the outer edge of the second frame 200, and the inner edge of the front side of the third overlap portion 420 and the inner edge of the front side of the third frame body 410 are located on the same straight line.

In this way, the third overlapping portion 420 can block the splicing gap of the second corner portion 230 at the front side or the gap that cannot completely accommodate the third overlapping portion 420, so as to ensure the integrity of the appearance of the frame assembly.

[0092] Further, such as Figure 1 and Figure 3 As shown, the third overlap portion 420 can extend to the outer edge of the second frame 200, and the inner edge of the front side of the third overlap portion 420 and the inner edge of the front side of the third frame body 410 are located on the same straight line. Figure 1 From the front perspective shown, the front side of the third frame 400 can extend to the left and right ends of the frame assembly to form a through visual effect, thereby making the display device using the frame assembly more beautiful as a whole.

[0096] In practical applications, the fourth overlap portion 232 can be recessed inward from the outer side of the second corner portion 230, so that when splicing, the fourth overlap portion 232 can be inserted into the hollow cavity formed by the third frame 400. The third frame 400 can be locked and connected to the fourth overlap portion 232 by screws passing through the outer side of the third frame 400.
