Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a lamp panel and display device. Background Technology

[0002] A light panel is a component of a display device, providing a light source for the display panel to display images.

[0003] The display device may also include a diffuser plate, which is located between the display panel and the lamp panel. To support the diffuser plate, a diffuser plate bracket is typically connected to the lamp panel.

[0004] However, during transportation, the number of light panels that can be placed in a single package is relatively small due to the height of the diffuser plate brackets installed on the light panels, resulting in low transportation efficiency. Summary of the Invention

[0005] This application provides a light panel and display device to solve the problem of low packaging and transportation efficiency of light panels.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] On one hand, this application provides a lamp panel, including a substrate and a support member. The support member is located on one side of the substrate and connected to the substrate. The support member is used to support a diffuser plate. A receiving cavity is formed inside the support member, and an opening communicating with the receiving cavity is provided at the end connected to the substrate. A clearance hole is provided on the substrate. The clearance hole is disposed opposite to the opening, allowing a support member of another lamp panel to pass through and extend into the receiving cavity.

[0008] The lamp panel provided in this application embodiment allows a support member on one substrate to pass through a clearance hole on an adjacent substrate and extend into a receiving cavity inside the support member on the other substrate when multiple lamp panels are packaged and transported. This creates a height overlap between the support members on adjacent substrates, reducing the distance between them and allowing more lamp panels to be placed in the packaging box, thereby improving the packaging and transport efficiency of the lamp panels.

[0009] In some embodiments, the support member has a sidewall. The sidewall is disposed around the axis of the clearance hole, forming a receiving cavity with an opening. One end of the sidewall near the substrate is disposed around the periphery of the clearance hole and connected to the substrate. The area of ​​the outer contour of the sidewall's cross-section gradually decreases along a direction perpendicular to and away from the substrate, and a portion of the sidewall's cross-section, when projected perpendicularly onto the substrate surface near the support member, lies within the clearance hole, allowing the portion of the sidewall away from the substrate to pass through the clearance hole. The cross-section of the sidewall is parallel to the substrate surface near the support member.

[0010] In some embodiments, the area of ​​the outer contour of the cavity's cross-section gradually decreases along a direction perpendicular to the substrate and away from the substrate. The cross-section of the cavity is parallel to the surface of the substrate near the support.

[0011] In some embodiments, the vertical projection of the outer contour of the sidewall along the first cross-section onto the surface of the substrate near the support coincides with the peripheral wall of the clearance hole. The first cross-section is parallel to the surface of the substrate near the support. The distance between the first cross-section and the substrate, along a direction perpendicular to the surface of the substrate near the support, is less than the distance between the first cross-section and the end of the support furthest from the substrate.

[0012] In some embodiments, the lamp board further includes solder pads. The solder pads are disposed on the surface of the substrate near the support member. The solder pads are soldered to the end of the support member near the substrate. The support member is connected to the substrate via the solder pads.

[0013] In some embodiments, the clearance hole includes a first portion and a plurality of second portions. The first portion is disposed opposite to the opening. The plurality of second portions are located on the periphery of the first portion and are spaced apart around the periphery of the first portion. A pad is disposed between two adjacent second portions along the circumferential direction of the first portion. The support member includes a main body and a plurality of limiting portions. A receiving cavity is formed inside the main body. An opening communicating with the receiving cavity is formed at one end of the main body near the substrate. The end of the main body near the substrate is soldered to the pad. The plurality of limiting portions are located on the side of the main body near the substrate and are connected to the main body. The plurality of limiting portions are spaced apart along the circumferential direction of the opening. One limiting portion engages within one of the second portions.

[0014] In some embodiments, the second portion is elongated. One end of the second portion is connected to the first portion, and the other end extends radially away from the first portion. The limiting portion is also elongated, with one end extending radially away from the opening.

[0015] In some embodiments, a plurality of second portions are evenly spaced circumferentially along the first portion. A plurality of limiting portions are evenly spaced circumferentially along the opening.

[0016] In some embodiments, the number of second portions is even, and the number of second portions is greater than two. The extension direction of the plurality of second portions passes through the axis of the first portion, and they are arranged symmetrically in pairs about the axis of the first portion. The number of limiting portions is also even, and the number of limiting portions is also greater than two. The extension direction of the plurality of limiting portions passes through the axis of the opening, and they are arranged symmetrically in pairs about the axis of the opening.

[0017] On the other hand, embodiments of this application provide a display device, including a display panel, a back plate, a diffuser plate, and any one of the aforementioned lamp plates. The display panel has a display surface and a back surface disposed opposite to the display surface. The back plate is located on the side where the back surface of the display panel is located, forming a mounting cavity with the display panel. The lamp plate is disposed within the receiving cavity and connected to the back plate. A support member is located on the side of the substrate near the display panel. The diffuser plate is located on the side of the lamp plate near the display panel and abuts against the support member.

[0018] Since the display device provided in this application includes any of the above-mentioned light panels, it can solve the same technical problems as the above-mentioned light panels and achieve the same technical effects, it will not be described again here. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "center", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0039] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more.

[0040] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0041] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] With the improvement of people's living standards, display devices have become an indispensable household appliance. Display devices generally include a display panel. The display panel can be self-emissive or require an external light source.

[0044] For display devices where the display panel cannot emit light itself, the display device may include a backlight module and a display panel. Depending on the position of the backlight source in the backlight module, it can be divided into direct-lit backlight modules and edge-lit backlight modules.

[0045] For display devices with direct-lit backlight modules, the backlight module may include a lamp panel and a diffuser plate. The lamp panel is disposed opposite to the display panel and is used to provide light to the display panel. The diffuser plate is located between the lamp panel and the display panel and is used to diffuse the light emitted by the lamp panel.

[0046] In related technologies, a diffuser plate bracket is typically provided on the lamp plate to support and fix the diffuser plate. For example... Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a lamp panel 010 and a diffuser plate support 011 in related technologies. Figure 2 This is a front view of a diffuser plate bracket 011 mounted on a lamp plate 010, which includes a substrate 012 and a light source 013. The diffuser plate bracket 011 is located on the side of the substrate 012 closest to the light source 013 and is fixedly connected to the substrate 012.

[0047] In the Figure 1 and Figure 2 When the lamp panel 010 with the diffuser plate bracket 011 shown is packaged and transported, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure when multiple lamp panels 010 with diffuser plate brackets 011 are packaged in a packaging box 014. Because the diffuser plate brackets 011 are relatively high and there is a large gap between two adjacent base plates 012, the number of lamp panels 010 that can be placed in a single packaging box 014 is reduced, resulting in low packaging and transportation efficiency of the lamp panels 010.

[0048] Based on this, embodiments of this application provide a display device, such as... Figure 4 As shown, Figure 4 This is a schematic diagram of the overall structure of the display device 100 provided in the embodiments of this application. The display device 100 may include a display panel 10, a back plate 20, and a lamp plate 30.

[0049] like Figure 4 As shown, the display panel 10 has a display surface ( Figure 4 The upper surface of the display panel 10 and the back surface opposite to the display surface ( Figure 4 The surface on the lower side of the display panel 10. The display surface can be used to display images. For example, the display panel 10 can be a liquid crystal display panel.

[0050] A liquid crystal display (LCD) panel contains multiple subpixels, which are the smallest imaging units of the LCD panel. A pixel is formed by several adjacent subpixels emitting different types of light. For example, a pixel consists of consecutive red (R), green (G), and blue (B) subpixels. In this case, the color displayed by the pixel can be adjusted by changing the proportions of R, G, and B light rays in different pixels.

[0051] Continue to refer to Figure 4The back plate 20 is located on the side where the back of the display panel 10 is located, and together with the display panel 10, forms a mounting cavity 201, which provides mounting space. For example, as shown... Figure 4 As shown, the back panel 20 and the display panel 10 can form a roughly trapezoidal mounting cavity 201.

[0052] Continue to refer to Figure 4 The light panel 30 is located inside the mounting cavity 201 and is used to provide light so that the display panel 10 can display images. The light panel 30 can emit light towards the back of the display panel 10, and after the back of the display panel 10 receives the light, the display surface can display images.

[0053] Depending on the size of the display panel 10 and the lamp panel 30, the display device 100 may include multiple lamp panels 30. The multiple lamp panels 30 together emit light towards different positions on the back of the display panel 10, so that each position of the display panel 10 can receive the light emitted by the lamp panels 30.

[0054] like Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of a lamp board 30 provided in an embodiment of this application. The lamp board 30 may include a substrate 31 and a plurality of light sources 32 disposed on the substrate 31. The substrate 31 can provide mounting positions for the light sources 32, facilitating the installation of the light sources 32.

[0055] Multiple light sources 32 can be evenly spaced and arranged on the substrate 31. The light sources 32 can emit light to illuminate the display panel 10. Figure 4 It provides light. The type of light source 32 can be selected according to the actual situation. For example, the light source 32 can be a Mini-LED light-emitting chip, which can be fixed on the substrate 31 by dispensing.

[0056] like Figure 4 As shown, the display device 100 may further include a diffuser plate 40, which is located between the lamp plate 30 and the display panel 10. The diffuser plate 40 can diffuse the light emitted by the light source 32, making the light distribution more uniform.

[0057] like Figure 4 As shown, the diffuser plate 40 is located on the side of the substrate 31 closer to the light source 32. The light emitted by the light source 32 becomes more uniform after being diffused by the diffuser plate 40, and then it is transmitted to the display panel 10 for image display, resulting in a better display effect.

[0058] Continue to refer to Figure 4To support the diffuser plate 40, the lamp plate 30 may also include a support member 33. The support member 33 is located on one side of the substrate 31 and is connected to the substrate 31. The support member 33 can be used to support the diffuser plate 40.

[0059] like Figure 4 As shown, the support member 33 is located on the side of the substrate 31 near the display panel 10, and the diffuser plate 40 can abut against the support member 33 of the lamp plate 30. Thus, the support member 33 can support the diffuser plate 40, and the diffuser plate 40 can be fixed to the side of the substrate 31 near the display panel 10 and is spaced apart from the substrate 31.

[0060] To reduce the space occupied by the light panel 30 during transportation and improve its transportation efficiency. For example... Figure 6 As shown, Figure 6 for Figure 5 The enlarged view at point A shows that the support member 33 has an internal cavity 331. One end of the support member 33, which connects to the substrate 31, has an opening communicating with the cavity 331. Conversely, the substrate 31 has a clearance hole 311, which is positioned opposite the opening. The clearance hole 311 allows a support member 33 of another lamp panel 30 to pass through and extend into the cavity 331.

[0061] Therefore, as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the lamp panel 30 provided in this application embodiment when it is packaged in a packaging box 200. When multiple lamp panels 30 are packaged and transported, the support member 33 on one of the substrates 31 can pass through the clearance hole 311 on another substrate 31 adjacent to it and extend into the receiving cavity 331 inside the support member 33 on the other substrate 31.

[0062] In this way, there is an overlap between the support members 33 on two adjacent substrates 31, which reduces the distance between the two adjacent substrates 31, allowing more light panels 30 to be placed in the packaging box 200, thereby improving the packaging and transportation efficiency of the light panels 30.

[0063] It is understandable that during packaging and transportation, multiple lamp panels 30 with the same structure can be placed in the same packaging box 200, so that the support member 33 on one of the substrates 31 can be arranged opposite to the clearance hole 311 on the adjacent substrate 31, so that the support member 33 can extend into the interior of the support member 33 on the other substrate 31.

[0064] Of course, two different specifications of lamp panels 30 can be placed alternately in the same packaging box 200. In this case, in order to enable the support member 33 on one of the substrates 31 to be positioned opposite to the clearance hole 311 on the adjacent substrate 31, the clearance holes 311 on the two different specifications of substrates 31 need to be positioned according to the actual situation.

[0065] In addition, such as Figure 7 As shown, when packaging and transporting the light panel 30, multiple light panel support boxes 300 can be stacked inside the packaging box 200. The light panel 30 can be fixed inside the packaging box 200 by the light panel support boxes 300. Thus, the light panel support boxes 300 can prevent squeezing between adjacent light panels 300, ensuring that the light panel 30 is not damaged during packaging and transportation.

[0066] In some embodiments, such as Figure 6 As shown, the support member 33 has a sidewall 332. The sidewall 332 is arranged around the axis of the clearance hole 311, forming a receiving cavity 331 with an opening. One end of the sidewall 332 near the substrate 31 is arranged around the periphery of the clearance hole 311 and connected to the substrate 31. Thus, the support member 33 can be fixed to the periphery of the clearance hole 311 by the end of the sidewall 332 near the substrate 31, so that the opening and the clearance hole 311 can be arranged opposite to each other.

[0067] Among them, such as Figure 6 As shown, along a direction perpendicular to substrate 31 and away from substrate 31, i.e. Figure 6 In the X direction shown, the area of ​​the outer contour of the sidewall 332 gradually decreases, and the vertical projection of a portion of the sidewall 332's cross-section onto the surface of the substrate 31 near the support member 33 lies within the clearance hole 311, so that the portion of the sidewall 332 away from the substrate 31 can pass through the clearance hole 311. The cross-section of the sidewall 332 is parallel to the surface of the substrate 31 near the support member 33.

[0068] Therefore, when multiple lamp panels 30 are stacked, the cross-sectional area of ​​the support member 33 at the end away from the substrate 31 is the smallest. The vertical projection of the outer contour at this point onto the surface of the substrate 31 near the support member 33 is located in the clearance hole 311, thereby ensuring that the support member 33 can pass through the clearance hole 311 on another substrate 31 and extend into the mounting cavity 201 of the support member 33 provided thereon.

[0069] In some embodiments, such as Figure 6 As shown, along a direction perpendicular to substrate 31 and away from substrate 31, i.e. Figure 6 In the X direction, the area of ​​the outer contour of the cavity 331 gradually decreases. The cross-section of the cavity 331 is parallel to the surface of the substrate 31 near the support member 33.

[0070] like Figure 6 As shown, the area of ​​the outer contour of the sidewall 332's cross-section gradually decreases along a direction perpendicular to and away from the substrate 31. Based on Figure 6 The cavity 331 inside the support member 33 is designed such that the cross-sectional area of ​​the cavity 331 in the support member 33 at the position away from the substrate 31 is also smaller. In this way, when designing the support member 33, the wall thickness of the sidewall 332 can be kept consistent at all positions along the direction perpendicular to the substrate 31, thus ensuring the structural strength of the support member 33.

[0071] Of course, in other embodiments, such as Figure 8 As shown, Figure 8 This is a partial enlarged view of the support member 33 in another substrate 31 provided in an embodiment of this application. Along a direction perpendicular to and away from the substrate 31, the cross-sectional area of ​​the receiving cavity 331 can remain unchanged. In this case, the thickness of the sidewall 332 near the substrate 31 is relatively thick, which can provide a better supporting effect.

[0072] In some embodiments, such as Figure 6 As shown, the vertical projection of the outer contour of the sidewall 332 cut along the first section S onto the surface of the substrate 31 near the support member 33 coincides with the peripheral wall of the clearance hole 311. The first section S is parallel to the surface of the substrate 31 near the support member 33.

[0073] Wherein, along the direction perpendicular to the surface of the substrate 31 near the support member 33, the distance between the first cross section S and the substrate 31 can be less than the distance between the first cross section S and the end of the support member 33 away from the substrate 31. Thus, when two lamp panels 30 are stacked together, at least half of the support member 33 on one of the substrates 31 can pass through the clearance hole 311, thereby making the gap between the two adjacent substrates 31 smaller and ensuring the packaging and transportation efficiency of the lamp panels 30.

[0074] It is understood that the relationship between the distance L1 between the first cross section S and the substrate 31 and the distance L2 between the first cross section S and the end of the support member 33 away from the substrate 31, along the direction perpendicular to the surface of the substrate 31 near the support member 33, can be designed according to actual conditions. For example, L1 can be equal to L2 / 2, or L1 can also be equal to L2 / 3.

[0075] Of course, in other embodiments, the distance between the first cross-section S and the substrate 31 may also be greater than the distance between the first cross-section S and the end of the support member 33 away from the substrate 31. In this case, a small portion of the support member 33 may pass through the clearance hole 311 on another substrate 31.

[0076] In some embodiments, in order to fix the support 33, such as Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of a substrate 31 near the light source 32, provided in an embodiment of this application. The lamp board 30 also includes pads 34. The pads 34 are disposed on the surface of the lamp board 30 near the support member 33. The pads 34 and the support member 33 ( Figure 8 The support member 33 is welded to one end near the lamp panel 30, and is connected to the substrate 31 via the solder pad 34. Thus, the support member 33 can be soldered to the substrate 31 via the solder pad 34, making the connection more secure and less likely to separate from the substrate 31.

[0077] Of course, the support member 33 can also be fixed to the substrate 31 in other ways. For example, in some other embodiments, the support member 33 can also be glued to the substrate 31. Alternatively, the support member 33 can also be snapped onto the substrate 31 by a snap-fit ​​structure. The specific choice can be made according to the actual situation, and this is only illustrated as an example.

[0078] In some embodiments, such as Figure 9 As shown, the clearance hole 311 may include a first portion 3111 and a plurality of second portions 3112. The first portion 3111 is disposed opposite to the opening. The plurality of second portions 3112 are located on the periphery of the first portion 3111 and are spaced apart around the periphery of the first portion 3111. A pad 34 is disposed between two adjacent second portions 3112 along the circumference of the first portion 3111.

[0079] Correspondingly, such as Figure 10 As shown, Figure 10 This is a structural schematic diagram of a support member 33 with an open side provided in an embodiment of this application. The support member 33 may include a main body 333 and a plurality of limiting parts 334.

[0080] A receiving cavity 331 is formed inside the main body 333. The main body 333 is close to the substrate 31. Figure 9 One end of the main body 333 has an opening communicating with the receiving cavity 331. The end of the main body 333 closest to the substrate 31 is connected to the pad 34. Figure 9 Welding. Thus, the support member 33 can be welded to the substrate 31 through its main body 333. It is understood that the main body 333 has the aforementioned sidewall 332.

[0081] like Figure 10 As shown, multiple limiting portions 334 are located near the substrate 31 of the main body 333. Figure 9 On one side of the opening, it is connected to the main body 333. Multiple limiting parts 334 are spaced apart circumferentially along the opening. One limiting part 334 engages with a second part 3112 ( Figure 9 )Inside.

[0082] Therefore, when the support member 33 is mounted on the substrate 31, the limiting portion 334 of the support member 33 can extend into the second part 3112 of the clearance hole 311 for engagement. At this time, the support member 33 can be fixed in the corresponding position under the action of the limiting portion 334, thereby facilitating the connection between the main body 333 and the pad 34.

[0083] Furthermore, since the limiting part 334 is located within the second part 3112, the limiting part 334 can interact with the substrate 31, thereby making it difficult for the main body part 333 to move relative to the substrate 31, ensuring the firmness and stability of the connection between the main body part 333 and the substrate 31.

[0084] Of course, in other embodiments, such as Figure 11 As shown, Figure 11 This is a schematic diagram of another substrate 31 near the light source 32 provided in an embodiment of this application. The clearance hole 311 may also include only the first part 3111. Correspondingly, as Figure 12 As shown, Figure 12 This is a schematic diagram of another support member 33 provided in an embodiment of this application, showing the open side. The support member 33 may also consist only of the main body 333. In this case, during installation, the main body 333 can be directly soldered to the pad 34 to complete the installation and fixation of the support member 33 on the substrate 31.

[0085] In some embodiments, such as Figure 9 As shown, the second part 3112 is elongated. One end of the second part 3112 is connected to the first part 3111, and the other end extends radially away from the first part 3111. Based on this, the aforementioned clearance hole 311 can be manufactured directly, making the manufacturing process more convenient.

[0086] It is understandable that when the clearance hole 311 has different forms, the support member 33 has a corresponding structure to correspond to the clearance hole 311. For example, when the clearance hole 311 is... Figure 9 When the structure is shown, as Figure 10 As shown, the limiting part 334 is also elongated. Along the radial direction of the opening, one end of the limiting part 334 extends away from the opening, so that the limiting part 334 can smoothly extend into the second part 3112 of the clearance hole 311.

[0087] Of course, in other embodiments, such as Figure 13 As shown, Figure 13This is a schematic diagram of another substrate 31 near the light source 32 provided in an embodiment of this application. One end of the second part 3112 may not be connected to the first part 3111, that is, the first part 3111 and the second part 3112 are independent of each other. In this case, when making the clearance hole 311, the first part 3111 and the second part 3112 can be made separately.

[0088] Correspondingly, such as Figure 14 As shown, Figure 14 This is a schematic diagram of another support member 33 provided in this application embodiment, showing the structure with an open side. To allow the limiting part 334 to smoothly extend into the second portion 3112 of the clearance hole 311, there can be a gap between the end of the limiting part 334 near the opening and the edge of the opening along the radial direction of the opening. Therefore, when installing the support member 33, the limiting part 334 can smoothly extend into the second portion 3112 of the clearance hole 311.

[0089] In some embodiments, such as Figure 9 As shown, multiple second portions 3112 are evenly spaced along the circumferential intervals of the first portion 3111. Correspondingly, as... Figure 10 As shown, multiple limiting portions 334 are evenly spaced along the circumferential direction of the opening. Thus, when the multiple limiting portions 334 are respectively located within the multiple second portions 3112, the movement of the support member 33 can be restricted from each position, ensuring that the support member 33 can be firmly installed and fixed on the base plate 31.

[0090] In some embodiments, such as Figure 9 As shown, the number of second parts 3112 is even, and the number of second parts 3112 is greater than two. The extensions of multiple second parts 3112 pass through the axis of the first part 3111, and are arranged symmetrically in pairs about the axis of the first part 3111. When the extension direction of the second parts 3112 passes through the axis of the first part 3111, and is arranged symmetrically in pairs about the axis of the first part 3111, the structure of the clearance hole 311 is relatively simple and easier to manufacture.

[0091] Correspondingly, such as Figure 10 As shown, the number of limiting portions 334 is also an even number, and the number of limiting portions 334 is also greater than two. The extension direction of the plurality of limiting portions 334 passes through the axis of the opening, and they are arranged symmetrically in pairs about the axis of the opening. Similarly, the structure and position of the plurality of limiting portions 334 are relatively simple, which facilitates the fabrication of the support member 33. Of course, in some other embodiments, the number of second parts 3112 may also be an odd number. Correspondingly, the number of limiting portions 334 is the same as the number of second parts 3112.

[0092] It is understandable that the quantity of the second part 3112 can be designed according to the actual situation. For example, such as Figure 9 As shown, the number of second portions 3112 can be four, with the four second portions 3112 arranged symmetrically in pairs about the axis of the first portion 3111. Along the circumference of the first portion 3111, the included angle between any two adjacent second portions 3112 is 90°. Of course, the number of second portions 3112 can also be six, eight, etc. The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
