Referring toFIG.1,FIG.2andFIG.3, a display screen10provided by an embodiment of the present disclosure includes a lock body20, a display unit and a frame30. The display unit is configured to emit light to display an image. The display unit is received in a cavity enclosed by the frame30. The frame30serves as a carrier of the display unit and plays a certain protective role for the display unit. The display screen10may include one frame30or a plurality of frames30. When a plurality of frames30is included, the plurality of frames30are spliced with each other through lock bodies20. Since a display unit is provided in each frame30, the larger the number of frames30to be spliced, the larger the display area of the display screen10. Therefore, according to the requirements for implementing the size of the display area, different numbers of frames30can be utilized to splice each other to form the display screen10with different display area. The frame30includes a frame body100and an embedded member200; the embedded member200and the frame30are connected to each other.

Referring toFIGS.2,3and7, in some embodiments, the frame body100may be substantially rectangular; and the frame body100includes a longitudinal segment111and a transverse segment112; the number of the longitudinal segments111is two, and the two longitudinal segments111are substantially parallel to each other and spaced from each other. The number of the transverse segments112is two; and the two transverse segments112are also substantially parallel to each other and spaced from each other. One of the longitudinal segments111is connected between one end of one transverse segment112and one end of the other transverse segment112; and the other longitudinal segment111is connected between the other end of the one transverse segment112and the other end of the other transverse segment112. Each longitudinal segment111may be provided with at least one embedded member200and one mounting hole150, for example, each longitudinal segment111may be provided with two embedded members200and two mounting holes150; and the two embedded members200are respectively mounted in the two mounting holes150; the two embedded members200are arranged at intervals along an extension direction of the longitudinal segment111. Each transverse segment112may be provided with at least one embedded member200and one mounting hole150, for example, each transverse segment112may be provided with two embedded members200and two mounting holes150; and the two embedded members200are respectively mounted in the two mounting holes150; the two embedded members200are arranged at intervals along an extension direction of the transverse segment112. In other embodiments, the frame body100may also have a regular polygon shape, a circular shape, or an ellipse shape, and so on.

In some embodiments, the frame body100further includes a first reinforcement beam121and a second reinforcement beam122. The first reinforcement beam121and the second reinforcement beam122can intersect with each other, and can be connected and perpendicular to each other. The first reinforcement beam121is located between two longitudinal segments111, such that the first reinforcement beam121and the two longitudinal segments111are spaced apart; and both ends of the first reinforcement beam121are fixedly connected to the two transverse segments112respectively. The second reinforcement beam122is located between the two transverse segments112, such that the second reinforcement beam122and the two transverse segments112are spaced apart; and both ends of the second reinforcement beam122are fixedly connected to the two longitudinal segments111respectively. By arranging the first reinforcement beam121and the second reinforcement beam122, the structural strengths of the frame body100and the frame30can be reasonably enhanced.

In some embodiments, the frame body100is configured to have a first side frame131, a second side frame132, a front panel141and a back panel142; the first side frame131is arranged around the second side frame132, and the front panel141is connected to one end of the first side frame131and one end of the second side frame132; the back panel142is connected to the other end of the first side frame131and the other end of the second side frame132; the front panel141and the back panel142face opposite directions; and the front panel141faces the same direction as a light emission direction of the display unit, so that the back panel142faces a direction opposite to the light emission direction of the display unit. Obviously, the transverse segment112consists of one portion of the first side frame131, one portion of the second side frame132, one portion of the front panel141and one portion of the back panel142; and the longitudinal segment111consists of the other portion of the first side frame131, the other portion of the second side frame132, the other portion of the front panel141and the other portion of the back panel142.

The frame body100is provided with a mounting hole150; and the mounting hole150matches the embedded member200, that is, the mounting hole150is configured to mount the embedded member200, so that the embedded member200is embedded in the frame body100. The mounting hole150includes an intermediate cavity153, a first hole151and a second hole152; the first hole151and the second hole152are located on opposite sides of the intermediate cavity153. Specifically, the intermediate cavity153is jointly surrounded by the first side frame131, the second side frame132, the front panel141and the back panel142; the first hole151is provided on the first side frame131, and the first hole151passes through the entire first side frame131to communicate with the outside world and the intermediate cavity153. The second hole152is provided on the second side frame132; and the second hole152passes through the entire second side frame132to communicate with the outside world and the intermediate cavity153. Apertures of the first hole151and the second hole152may be substantially the same; and both the first hole151and the second hole152may be substantially rectangular.

Referring toFIGS.5,6and7, in some embodiments, the embedded member200includes a carrier210, a first boss221and a second boss222. The carrier210has a substantially plate-type structure. The carrier210has a first surface211and a second surface212. The first surface211and the second surface212are spaced apart in a direction of a thickness of the carrier210and face opposite directions. The first boss221is fixed on the first surface211, and the first boss221protrudes from the first surface211to a certain height in the direction of the thickness of the carrier210. In other words, the first boss221is provided on and protruding from the first surface211. The second boss222is fixed on the second surface212, and the second boss222protrudes from the second surface212to a certain height in the direction of the thickness of the carrier210. In other words, the second boss222is provided on and protruding from the second surface212.

For the mounting of the embedded member200, the carrier210is matched with the intermediate cavity153; and in a direction from the front panel141to the back panel142, the thickness of the carrier210gradually decreases, and the width of the intermediate cavity153also decreases, such that the carrier210is sandwiched in the intermediate cavity153. Specifically, the first surface211of the carrier210can be stacked on the first side frame131, and the second surface212of the carrier210can be stacked on the second side frame132. The first boss221is matched with the first hole151, and the second boss222is matched with the second hole152.

In some embodiments, both the first surface211and the second surface212of the carrier210are provided with concave-convex structures213. The concave-convex structure213on the first surface211can be in contact with the first side frame131. By the action of the concave-convex structure, an engagement structure can be formed between the carrier210and the first side frame131, thereby improving a binding force between the carrier210and the first side frame131. The concave-convex structure213on the second surface212can be in contact with the second side frame132. By the action of the concave-convex structure213, an engagement structure can be formed between the carrier210and the second side frame132, thereby improving the binding force between the carrier210and the second side frame132. Therefore, by providing the concave-convex structures213on the first surface211and the second surface212, the connection force between the entire embedded member200and the frame body100can be improved.

In some embodiments, for example, referring toFIG.3, each embedded member200can be independently provided on the frame body100. For another example, referring toFIG.4, the frame30may further include a connector300; and the connector300may have a substantially plate-type structure. The connector300is fixedly connected between two adjacent embedded members200, such that the two embedded members200are associated through the connector300, that is, the two embedded members200are not independent, so that the two embedded members200can only be simultaneously mounted on the frame body100. By providing the connector300, the assembly efficiency of the embedded member200and the structural strength of the entire frame30can be improved to a certain extent. Specifically, two embedded members200, when provided on the transverse segment112of the frame body100, can be fixedly connected through the connector300. Two embedded members200, when provided on the longitudinal segment111of the frame body100, can also be fixedly connected by the connector300. Of course, for two adjacent embedded members200provided on the transverse segment112and the longitudinal segment111, the two adjacent embedded members200can also be fixedly connected through the connector300.

The embedded member200is configured to mount the lock body20. For the splicing of two adjacent frames30, the lock body20simultaneously connects the embedded members200on the two adjacent frames30, thereby implementing the splicing between the frames30. The two transverse segments112of the frame30are spaced apart in an up-down direction. The embedded members200on the transverse segment112implement the splicing between the frames30in the up-down direction through the lock body20. The two longitudinal segments111of the frame30are spaced apart in a left-right direction; and the embedded members200on the longitudinal segment111implement the splicing between the frames30in the left-right direction through the lock body20. The lock body20can change a mounting angle, accordingly a splicing angle between the left and right frames30can be adjusted, so that the spliced display screen10can have a flat surface or a curved surface. The curved surface includes a convex arc surface, a concave arc surface or a wave shape face and so on. Since the splicing angle between the frames30can be adjusted, the shape of the display screen10can be made more diverse, so that the display screen10can be applied to more installation environments.

The frame body100is made of a carbon fiber or glass fiber material; and the embedded member200is made of a metal or plastic material, such that the machining property of the embedded member200is better than that of the frame body100. In other words, during the machining, the embedded member200has a higher processing efficiency and a processing accuracy relative to the frame body100.

The manufacture of the entire frame30may include the following steps. At the first step, an embedded member200and a plurality of laminate bodies made of the carbon fiber or glass fiber material are provided; each laminate body is provided with a hole structure; the laminate bodies form an intermediate blank in a mold through stacking, bending and wrapping. Of course, in the process of forming the intermediate blank in the mold, the embedded member200is embedded in the intermediate blank, and the embedded member200is matched with the hole structure in the laminate body; and the hole structure in the laminate body forms a part of the formed mounting hole150. At the second step, a pressure is applied to the intermediate blank in the mold, such that the intermediate blank is compression-molded to form the frame body100under the action of pressure. In the process that the intermediate blank is compression-molded, a bonding force is generated between the embedded member200and the intermediate blank, and after the intermediate blank is finally transformed into the frame body100, a stable and reliable connection relationship is formed between the embedded member200and the frame body100. Since both the first surface211and the second surface212of the embedded member200are provided with the concave-convex structures213, during the compression molding process of the intermediate blank, an engagement relationship is formed between the embedded member200and the intermediate blank under the action of pressure, which finally causes an engagement structure between the embedded member200and the molded frame body100, thereby improving the connection strength between the embedded member200and the frame body100. At the third step, the embedded member200is machined by a Computer Number Control (CNC) technology to ensure that the embedded member200can quickly process the mounting structure for mounting the lock body20, and to ensure that the mounting structure has a reasonable shape and a dimensional accuracy, thereby improving the processing efficient and accuracy of the mounting structure, so that the embedded member200can satisfy the mounting requirements of the lock body20.

If the entire frame30is made of an aluminum alloy material, under the condition that the volume is kept constant, the weight of the frame30made of the aluminum alloy material is larger while the structural strength is lower. Therefore, in order to ensure the structural strength, the frame30made of the aluminum alloy material definitely has a sufficient volume, accordingly the weight of the frame30made of the aluminum alloy material is increased, which is not conducive to the lightweight design of the frame30. For example, the volume of the frame30is reduced in order to satisfy the lightweight design of the frame30, so that the structural strength of the frame30made of the aluminum alloy material cannot satisfy the actual requirements, as a result the frame30made of the aluminum alloy material cannot be of the lightweight design and the high strength design of products.

If the entire frame30is made of a composite material such as carbon fiber or glass fiber and is compression-molded, compared to the frame30made of the aluminum alloy materials, the frame30made of the composite material has less weight and higher structural strength at the same volume, so that the frame30completely made of the composite material can satisfy the lightweight design and high strength design of the products. However, as for the frame30completely made of the composite material and compression-molded, in the subsequent machining by the CNC technology to form the mounting structure for mounting the lock body20, the processing efficiency and processing accuracy of the frame30satisfy the design requirements, so that the mounting structure formed on the frame30cannot be configured to mount a lock body20applied to the frame30made of the aluminum alloy material. In other words, in view of the insufficient processing accuracy of the frame30completely made of the composite material, the lock body20that can be mounted on the frame30made of the aluminum alloy material cannot be mounted on the frame30made of the composite material, so that the frame30made of the composite material cannot use the same lock body20as the frame30made of the aluminum alloy material to implement the same splicing mode, resulting in that the splicing mode of the frame30made of the composite material is different from the splicing mode of the frame30made of the aluminum alloy material. At the same time, since the embedded member200has the mounting structure for mounting the lock body20, the mounting structure is relatively complicated. If the mounting structure is not formed by machining, the mounting structure is definitely formed by compression molding. However, it is usually difficult to form the mounting structure at one time by compression molding in a mold. Even if the mounting structure can be formed by compression molding, the design and processing costs of the mold are greatly increased, thereby increasing the manufacturing cost of the entire frame30.

As for the frame30in the above-mentioned embodiment, on the one hand, the frame body100is made of the carbon fiber or glass fiber material, under the same volume, the frame body100has a smaller volume and a greater structural strength, so that the lightweight and high strength designs of the whole frame30can be simultaneously implemented. On the other hand, the embedded member200made of the metal or plastic material has well machinability, which ensures that the embedded member200can be machined to have a mounting structure matching the lock body20, and the mounting structure satisfies the higher processing efficiency and accuracy, so that the mounting structure can be applied to mount the lock body20of the frame30made of the aluminum alloy material. In other words, for the lock body20that can be mounted on the frame30made of the aluminum alloy material, the lock body20can also be mounted on the frame30, so that the frame30made of the composite material can use the same lock body20as the frame30made of the aluminum alloy material to implement the same splicing mode, accordingly it is guaranteed that the splicing mode of the frame30made of the composite material is the same as the splicing mode of the frame30made of the aluminum alloy material.

Therefore, by the frame30in the above-mentioned embodiment, the lightweight and high strength designs can be implemented, and meanwhile the frame30made of the composite material can achieve the same splicing mode as the frame30made of the aluminum alloy material through the same lock body20. In other words, the splicing mode of the frame30made of the aluminum alloy material can be directly applied to the frame30made of the composite material to ensure that the user can also use the frame30made of the composite material without changing the existing splicing mode.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, all should be regarded as the scope described in the present disclosure.

The above-mentioned embodiments are merely some embodiments of the present disclosure, and the descriptions thereof are specific and detailed, but should not be construed as a limitation to the scope of the disclosure. It should be pointed out that those of ordinary skill in the art can make several modifications and improvements without departing from the concept of the present disclosure, which all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the appended claims.
