In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments.

The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Before the detailed description of the housing and the display device provided in the embodiments of the present disclosure, the following description of the related art is necessary:

in the related art, taking the housing of the display device shown in fig. 1 as an example, the display device is increased in size, and the length of the housing is increased accordingly. While the section bar of the frame body is in a non-closed section shape, for example, as shown in fig. 1 and fig. 2, the non-closed section shape can include two side edges 1 and a bottom edge 2, wherein the two side edges 1 need necessary hole or groove structures 11, and one side edge 1 needs to be provided with a non-closed small cavity 3, and an infrared lamp assembly and the like can be installed in the non-closed small cavity 3. Because the profile body is of a non-closed cross-sectional shape, its faces in all directions are incomplete, in particular at the location of the holes or grooves. There will be a weakened area of strength. In particular, the whole slot 4 of the non-closed small cavity is suspended at the main appearance surface (shown by the dotted line a in fig. 2) of the non-closed small cavity as one side of the slot is adjacent to the opening of the main body cavity of the section bar and the other side of the slot is provided with a hole or a groove arranged on the side edge.

The conventional processing mode of the section bar is as follows: a first step of integrally molding a body profile 10 by extruding a basic cross section through a die or the like, as shown in fig. 3 (a); secondly, as shown in fig. 3(b), performing CNC machining on each surface of the main body profile 10 to form a groove or hole structure 11, wherein in the machining process, a jig is required to be used for limiting and fixing the normal surface of the machined surface, and if the strength of the profile at the position where the jig is fixed is not enough, material deformation may be caused, and the final precision is affected; thirdly, as shown in fig. 3(c), riveting the stud 12 on the processed main body section 10 to complete the processing of the whole frame; and finally, carrying out surface treatment, such as wire drawing, anodic oxidation and the like. Because the length of the section bar is larger and the section bar has more weakening characteristics such as groove or hole structures 11, the deformation amount, particularly the linearity flatness in the length direction, is difficult to control.

In order to solve the above problems, embodiments of the present disclosure provide a frame and a display device, which can improve structural strength of the frame and reduce defects such as material deformation during a processing process of the frame.

Referring to fig. 4, the frame body provided in the embodiment of the present disclosure is elongated, and includes a main body cavity 100 with a non-closed cross section, a cavity wall of the main body cavity 100 includes a bottom wall portion 110 and at least one side wall portion 120, at least one small cavity 200 is disposed on the side wall portion 120, the small cavity 200 is formed by a first cavity wall 201 and a second cavity wall 202 in an enclosed manner, the first cavity wall 201 is formed by a part of the side wall portion 120, the second cavity wall 202 is at least partially located inside the main body cavity 100, a pre-groove area 210 to be grooved is disposed on the first cavity wall 100, and a reinforcing rib 220 is connected to the pre-groove area 210.

In the above scheme, the cross section of the main body cavity 100 of the frame body is a non-closed cross section, the side wall portion 120 of the main body cavity 100 of the frame body is provided with the small cavity 200, the small cavity is formed by surrounding the first cavity wall 201 and the second cavity wall 202, the first cavity wall 201 is formed by a part of the side wall portion 120, the first cavity wall 201 is reserved with a pre-slotting area 210 to be slotted, and the pre-slotting area 210 is connected with the reinforcing rib 220. Compared with the structure that no reinforcing rib is arranged at the slotting position of the small cavity in the prior art, the reinforcing rib is arranged, so that the slotting position of the small cavity with weaker strength of the frame body can be reinforced when the frame body is molded, the frame body can be in a closed section due to the fact that the reinforcing rib 220 is connected with the small cavity 200 in the pre-slotting region 210 when the subsequent processes such as slotting or hole structure processing are carried out, and deformation of the frame body is reduced when a jig fixture is used in the processing process. Before the surface treatment of the frame body, the reinforcing ribs 200 can be peeled off from the frame body by an external force, and the cross-sectional structure of the final frame body product (for example, the frame body of a display device) is obtained.

In the above embodiment, the first cavity wall 201 of the small cavity 200 is formed by the side wall portion 120 of the main body cavity 100, that is, the first cavity wall 201 may be regarded as a part of the side wall portion 120 and located on the appearance surface of the frame, the pre-groove region 210 is provided on the first cavity wall 201, and the open groove 211 formed after the rib 220 is peeled off is located on the appearance surface of the frame. Thus, when the frame is used as a frame of a display device, components such as an infrared filter 330 (as shown in fig. 7) can be disposed in the groove 211, which is beneficial to improving the appearance of the product. It is understood that, in other embodiments that are not illustrated, the specific location of the pre-groove region 210 may not be limited thereto.

It should be further noted that the pre-slotting region 210 can extend along the length direction of the frame body, and the slot 211 formed after the rib 220 is stripped can be a whole slot or a section of slot extending along the length direction of the frame body (for example, please refer to fig. 1 for the related art, the slot 4 is a whole slot).

FIG. 4 is a schematic structural view of the frame body before the ribs are peeled off in some embodiments; fig. 5 is a schematic structural view of the frame body after the reinforcing ribs are peeled off in some embodiments.

By arranging the reinforcing ribs 220, the appearance of a final product is not affected, peeling is easy, and effective reinforcing section bar supporting can be performed in the processing process.

In the frame body provided in the embodiment of the present disclosure, the final product obtained by peeling the reinforcing ribs 220 may be applied to a frame body of a display device, and may also be applied to other products.

In some exemplary embodiments, as shown in fig. 4 and 6, the reinforcing ribs 220 can be peeled off from the first cavity wall 201 under an external force, so that the small cavities 200 form a slotted non-closed structure. The reinforcing rib 220 includes: an extension part 221 and a connection part 222, wherein the extension part 221 extends in the extending direction of the first cavity wall 201 to fill the pre-groove region 210, the connection part 222 is located at two opposite ends of the extension part 221 and is connected with the first cavity wall 201, and the thickness of the connection part 222 is smaller than that of the extension part 221. With such an arrangement, the connecting portion 222 is thinner than the extending portion 221, so that a predetermined peeling line is formed at the connection between the reinforcing rib 220 and the first cavity wall 201, and the reinforcing rib 220 can be peeled off from the first cavity wall 201 along the peeling line by an external force.

Illustratively, the connecting portion 222 is a tapered structure having a thickness gradually decreasing from a side close to the extending portion 221 to a side far from the extending portion 221. By adopting the above scheme, the joint of the reinforcing rib 220 and the first cavity wall 201 adopts a size reducing structure, and the thickness of the structure is transited from large to small from the side close to the extension part 221 to the side far from the extension part 221 to the appearance edge of the slot 211 after the final product is peeled off, as shown in the position of the dotted line in fig. 6, so that the forming is convenient in terms of process implementation, for example, process equipment such as an extrusion forming die and the like can meet the forming requirement of the frame body, and the appearance of the formed product has no burrs.

In addition, in some embodiments, the ratio d1/d2 of the thickness d1 of the connecting portion 222 to the thickness d2 of the extending portion 221 ranges from 0.05 to 0.2. This is because, if the thickness d1 of the connecting portion 222 is too small, on the one hand, it is not easy to mold in terms of molding process, for example: taking the case of extrusion molding the frame body using a die as an example, if the thickness d1 of the connecting portion 222 is too small, the fluidity of the material is poor, and the molding in the die is difficult; on the other hand, if the thickness d1 of the connecting portion 222 is too small, the connecting portion is likely to break, resulting in poor reinforcing effect. If the thickness d1 of the connection portion 222 is too large, peeling is not likely to occur, and the appearance of the final product is impaired. In combination with the above factors, it is preferable that the thickness d1 of the connecting portion 222 is 0.15 to 0.3mm, which not only can satisfy the reinforcing requirement of the reinforcing rib, but also is easy to form in the process and peel in the subsequent process.

Furthermore, in some exemplary embodiments, the frame body is an integrally molded structure. For example, the frame body may be integrally formed by any suitable molding process such as extrusion molding or die molding.

Further, in some exemplary embodiments, the bottom wall portion 110 has a thickness greater than a thickness of the side wall portion 120. By adopting the scheme, when the length of the frame body is larger, the deformation of the frame body in the processing process, particularly the linearity and the flatness in the length direction are difficult to control. The sectional thickness of the bottom wall 110 may be increased inward without changing the external dimensions and the size of the mold, so that the distortion of the entire frame in the longitudinal direction may be reduced without changing the external dimensions of the frame, and the bottom wall 110 may have a structure such as a stud without affecting the caulking of the structure such as the stud 130 in the main body cavity 100, as shown in fig. 4. Illustratively, the bottom wall portion 110 has a thickness of 5 to 6mm, and the side wall portion 120 has a thickness of 2 to 3 mm.

Further, as shown in fig. 4, an inner chamfer 140 is provided at a connecting corner of the bottom wall portion 110 and the side wall portion 120. Taking fig. 4 as an example, when the main body cavity 100 is enclosed by the bottom wall 110 and at least one side wall 120, an inner chamfer 140 may be provided at the junction of the bottom wall 110 and the side wall 120. Thus, the distortion of the whole frame body in the length direction can be reduced, the appearance size of the frame body is not changed, the traditional stud riveting is not influenced, and the forming die does not need to be greatly changed.

Illustratively, the inner chamfer 140 may be a round chamfer with a round radius of 3-7 mm; alternatively, the inner chamfer 140 may be an oblique chamfer with an inclination of 45 ± 5 ° and an orthographic projection width of the oblique edge on the bottom wall 110 of 3-6 mm. Due to the arrangement, the strength of the frame body is better, the appearance of a product cannot be influenced, and the change of a forming mold is small. It should be understood that the specific structure, the specific dimensional parameters, etc. of the inner chamfer 140 are not limited thereto.

In addition, in some embodiments, the cavity wall of the body cavity 100 is further provided with a groove or hole structure. That is, the frame body may be provided with a necessary groove or hole structure. As exemplified by fig. 4 and fig. 7, the main body cavity 100 is surrounded by two side wall portions 120 and a bottom wall portion 110, the two side wall portions 120 can be divided into a first side wall portion and a second side wall portion, the small cavity 200 is arranged on the first side wall portion 120, and a plurality of first groove or hole structures 121 are arranged on the side wall portion 120, which is close to the bottom wall portion 110, of the small cavity 200; the second sidewall portion 120 is provided with a plurality of second groove or hole structures. With such an arrangement, since the non-closed cross-sectional shape of the main body cavity 100 may include two side wall portions 120 and a bottom wall portion 110, wherein the two side wall portions 120 are respectively provided with the necessary hole or groove structures, and one side wall portion is required to be provided with the non-closed small cavity 200, an infrared lamp assembly or the like can be installed in the non-closed small cavity 200. Since the body cavity has a non-closed cross-sectional shape, the faces thereof in all directions are incomplete, particularly at the location of the holes or grooves, and thus weakened zones of strength may exist. If no reinforcing rib is arranged in the area to be grooved of the small cavity, namely, the section shape of the small cavity is a non-closed section, the whole cavity is grooved, and one side of the small cavity is adjacent to the opening of the main cavity of the section bar, and the other side of the small cavity is provided with a first groove or hole structure arranged on the side edge of the same side, so that the main appearance surface of the whole non-closed small cavity is suspended. In the embodiment, the reinforcing ribs are arranged in the area to be grooved, so that the small cavity and the first groove or hole structure can be machined firstly in the machining process even if the small cavity and the first groove or hole structure are arranged on the side wall part on one side, and the small cavity keeps a closed section due to the reinforcing effect of the reinforcing ribs, so that the small cavity is not easy to deform. That is to say, the embodiment of the present disclosure can realize a frame structure in which holes or groove structures are respectively formed on two side wall portions, and a small cavity is formed on one side wall portion, and the structure is not easily deformed in processing.

It will be understood that, in practical applications, the sidewall portion may be provided with no groove or hole structure, or only one sidewall may be provided with a groove or hole structure, which is not limited thereto.

In some embodiments, as shown in fig. 5, the second cavity wall 202 has a substantially U-shaped cross section, and surrounds the first cavity wall 201 to form the mini-cavity 200. The second cavity wall 202 includes a first sub-wall 2021, a second sub-wall 2022, and a third sub-wall 2023 connected in sequence. The first sub-wall 2021 and the third sub-wall 2023 are respectively connected to two ends of the first cavity wall 201, the first sub-wall 2021 is located on one side of the third sub-wall 2023 close to the bottom wall, and the pre-groove region 210 may be located at a connection position of the first cavity wall 201 and the third sub-wall 2023. Thus, the first cavity wall 201 and the third sub-wall 2023 are separated by the slot 211 after the stiffener is stripped. Thus, when the frame body is used as a frame body of a display device, according to actual product requirements, components such as the infrared filter strip 330 are arranged in the slot 211, and taking the direction shown in fig. 7 as an example, the position of the slot 211 is closer to the upper side edge of the frame body, which is more beneficial to improving the product aesthetic property. It is understood that, in other embodiments that are not illustrated, the specific location of the pre-groove region 210 may not be limited thereto.

In some embodiments, as shown in fig. 5, the cavity opening direction (i.e., the direction indicated by the arrow X1) of the main body cavity 100 faces a direction away from the bottom wall 110, and the opening direction (i.e., the direction indicated by the arrow X2) of the slot 211 faces a direction away from the bottom wall 110 and forms an angle of 70-90 ° with respect to the opening direction of the cavity opening.

The cross section of the body cavity 100 is a non-closed section, and the cavity opening direction of the body cavity 10 is an opening direction on the non-closed section. The opening direction of the slot 211 refers to the opening direction in the cross section. By adopting the above scheme, when the frame body is used as the frame body of the display device, and components such as the infrared filter strip are arranged in the notch 211 according to actual product requirements, as shown in fig. 7, the components such as the infrared filter strip 330 can be inclined relative to the side wall part of the frame body, which is more beneficial to meeting the requirements of functionality and beauty of the components such as the infrared filter strip.

Wherein, the inclination of infrared optical filter strip 330 is when 70 ~ 90, on the one hand, from the product outward appearance, more be favorable to the roughness and the aesthetic property of its outward appearance, on the other hand, the light outgoing angle of infrared optical filter strip 330 satisfies the functional demand of product design in this inclination. If the inclination angle of the infrared filter strip 330 is smaller than 70 °, the inclination angle of the infrared filter strip 330 is too large in appearance, and the appearance is poor in aesthetic property; from the aspect of the light emergent angle, the light emergent effect is poor, and the functional requirements such as the light emergent angle and the like are not met.

In addition, as shown in fig. 4, in some embodiments, the small cavity 200 is located at an end of the side wall part 120 away from the bottom wall part 110. That is, the small cavity 200 is located at the cavity opening end of the main body cavity 100. This embodiment can be applied to some practical display products, and when an infrared lamp assembly is installed in the small cavity 200 of the practical display product, taking the direction shown in fig. 7 as an example, the small cavity 200 needs to be arranged at the upper side edge, i.e. the cavity opening end of the main body cavity 100. It is of course understood that in other non-illustrated embodiments, the small cavity 200 may be disposed at one end of the side wall portion 120 close to the bottom wall portion 110 or at an intermediate position of the side wall portion 120.

In addition, when the frame is applied to a display device, the slot 211 may be used to mount components such as the infrared filter strip 330, and therefore, a groove 211a may be further disposed on an edge of the slot 211, as shown in fig. 5, 7 and 9, and the components such as the infrared filter strip 330 may be embedded into the groove 211 a. The groove 211a may divide the edge of the slot 211 into an outer portion 211b and an inner portion 211c, wherein the rib 220 may be coupled to the outer portion 211 b. Thus, in some embodiments, the outer portion 211b of the edge of the slot 211 may be a ground or cut surface, or the outer portion 211b of the edge of the slot 211 may have an irregular surface with small protrusions 212 formed by pulling the bead. The inner portion 211c of the edge of the slot 211 may be a regular flat surface formed by a molding process. Fig. 5 is a schematic structural diagram of a frame body according to another aspect of the disclosure.

In addition, as shown in fig. 5, an embodiment of the present disclosure further provides a frame body, the frame body is elongated, and includes a main body cavity 100 having a non-closed cross section in cross section, a cavity wall of the main body cavity 100 includes a bottom wall portion 110 and at least one side wall portion 120, at least one small cavity 200 is disposed on the side wall portion 120, the small cavity 200 is formed by a first cavity wall 201 and a second cavity wall 202 in an enclosed manner, the first cavity wall 201 is formed by a part of the side wall portion 120, the second cavity wall 202 is at least partially located inside the main body cavity 100, a slot 211 is disposed on the first cavity wall 100, and the slot 211 is formed by stripping a reinforcing rib reserved to be connected to the slot 211.

In the above solution, the frame body provided by another aspect of the present disclosure may be obtained by peeling the reinforcing ribs from the frame body in the exemplary embodiment shown in fig. 4.

In the above scheme, the cross section of the main body cavity 100 of the frame body is a non-closed cross section, the side wall portion 120 of the main body cavity 100 of the frame body is provided with the small cavity 200, the small cavity is formed by surrounding the first cavity wall 201 and the second cavity wall 202, the first cavity wall 201 is formed by a part of the side wall portion 120, the first cavity wall 201 is reserved with a pre-slotting area 210 to be slotted, and the pre-slotting area 210 is connected with the reinforcing rib 220. Compared with the structure that no reinforcing rib is arranged at the slotting part of the small cavity in the prior art, the reinforcing rib is arranged, so that the slotting position of the small cavity with weaker strength can be reinforced when the frame body is formed and processed, the frame body can be used for sealing the cross section of the small cavity 200 due to the fact that the reinforcing rib 220 is connected with the pre-slotting region 210 in subsequent processes such as slotting or hole structure processing, and the deformation of the frame body is reduced when a jig fixture is used in the processing process. Before the surface treatment of the frame body, the reinforcing ribs 200 can be peeled off from the frame body by an external force, and the cross-sectional structure of the final frame body product (for example, the frame body of a display device) is obtained.

In the above embodiment, the first cavity wall 201 of the small cavity 200 is formed by the side wall portion 120 of the main body cavity 100, that is, the first cavity wall 201 may be regarded as a part of the side wall portion 120 and located on the appearance surface of the frame, the pre-groove region 210 is provided on the first cavity wall 201, and the open groove 211 formed after the rib 220 is peeled off is located on the appearance surface of the frame. Thus, when the frame is used as a frame of a display device, components such as an infrared filter strip 330 (as shown in fig. 7) can be disposed in the slot 211, which is beneficial to improving the appearance of the product. It is understood that, in other embodiments that are not illustrated, the specific location of the pre-groove region 210 may not be limited thereto.

In some exemplary embodiments, the edges of the slot 211 have an irregular surface with small protrusions 212 formed by pulling the stiffener. In the above solution, since the slot 211 is formed by stripping the reserved reinforcing rib, the stripping process of the reinforcing rib 220 may be: the stiffener is then grasped from one end and pulled outward using a tool such as a nipper pliers, so that the joint between the stiffener 220 and the edge of the channel 211 (i.e., the edge of the channel 211) peels away from the first cavity wall 201. In the actual operation process, the joint of the reinforcing rib and the edge of the slot 211 is pulled to cause an uneven irregular surface, and compared with the scheme that reinforcing ribs are not used in the related art, the edge of the slot 211 has an irregular protrusion, but the protrusion has a small size and does not affect the assembly and the function of the components at the slot, for example, when the slot is used for installing an infrared mounting bar, the assembly, the sending and the receiving functions of the infrared mounting bar are not affected.

The groove 211a may divide the edge of the slot 211 into an outer portion 211b and an inner portion 211c, wherein the rib 220 may be coupled to the outer portion 211 b. Thus, in some embodiments, the outer portion 211b of the edge of the slot 211 may be a ground or cut surface, or the outer portion 211b of the edge of the slot 211 may have an irregular surface with small protrusions 212 formed by pulling the bead. The inner portion 211c of the edge of the slot 211 may be a regular flat surface formed by a molding process.
