Description

Technical Field

[0001] The present application relates to the technical field of display equipment, and in particular to a light board and a display device. Background Art

[0002] The light board is a component of the display device, and can provide light source for the display panel of the display device so that the display panel can display images.

[0003] The display device may further include a diffusion plate, which is located between the display panel and the light board. In order to support the diffusion plate, a diffusion plate bracket is generally connected to the light board to support the diffusion plate.

[0004] However, during the transportation of the light panels, the number of light panels that can be placed in a single packaging box is small due to the high height of the diffusion plate bracket installed on the light panels, and the transportation efficiency of the light panels is low. Summary of the invention

[0005] The present application provides a light board and a display device, which are used to solve the problem of low efficiency in light board packaging and transportation.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] On the one hand, an embodiment of the present application provides a light board, 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. A receiving cavity is formed inside the support member, and an opening connected to the receiving cavity is provided at one end connected to the substrate. A avoidance hole is provided on the substrate. The avoidance hole is arranged opposite to the opening, and is used to allow a support member of another light board to pass through and extend into the receiving cavity.

[0008] In the light board provided in the embodiment of the present application, when multiple light boards are packaged and transported, the support member on one substrate can pass through the avoidance hole on another adjacent substrate and extend into the accommodating cavity inside the support member on the other substrate. In this way, there is an overlapped height between the support members on the two adjacent substrates, so that the distance between the two adjacent substrates is reduced, and more light boards can be placed in the packaging box, thereby improving the packaging and transportation efficiency of the light boards.

[0009] In some embodiments, the support member has a side wall. The side wall is arranged around the axis of the avoidance hole to form a receiving cavity with an opening. The end of the side wall close to the substrate is arranged around the periphery of the avoidance hole and is connected to the substrate. In the direction perpendicular to the substrate and away from the substrate, the area of ​​the outer contour of the cross section of the side wall gradually decreases, and the vertical projection of the cross section of part of the side wall on the surface of the side of the substrate close to the support member is located in the avoidance hole, so that the part of the side wall away from the substrate can pass through the avoidance hole. The cross section of the side wall is parallel to the surface of the side of the substrate close to the support member.

[0010] In some embodiments, the area of ​​the outer contour of the cross section of the accommodating cavity gradually decreases along a direction perpendicular to the substrate and away from the substrate, wherein the cross section of the accommodating cavity is parallel to the surface of the substrate on one side close to the support member.

[0011] In some embodiments, a vertical projection of the outer contour of the sidewall cut along the first section on the surface of the substrate close to the support member coincides with the peripheral wall of the avoidance hole. The first section is parallel to the surface of the substrate close to the support member. In the direction perpendicular to the surface of the substrate close to the support member, the distance between the first section and the substrate is less than the distance between the first section and the end of the support member away from the substrate.

[0012] In some embodiments, the light board further comprises a soldering pad. The soldering pad is disposed on a surface of a side of the substrate close to the support member. The soldering pad is welded to an end of the support member close to the substrate. The support member is connected to the substrate via the soldering pad.

[0013] In some embodiments, the avoidance hole includes a first part and a plurality of second parts. The first part is arranged opposite to the opening. The plurality of second parts are located on the circumferential side of the first part and are arranged at intervals around the circumferential side of the first part. A soldering pad is arranged between two adjacent second parts along the circumference of the first part. The support member includes a main body and a plurality of limiting parts. An accommodating cavity is formed inside the main body. An opening connected to the accommodating cavity is provided at one end of the main body close to the substrate. An end of the main body close to the substrate is welded to the soldering pad. The plurality of limiting parts are located on a side of the main body close to the substrate and are connected to the main body. The plurality of limiting parts are arranged at intervals along the circumference of the opening. A limiting part is snapped into a second part.

[0014] In some embodiments, the second portion is in the shape of an elongated strip. One end of the second portion is connected to the first portion, and the other end extends in a radial direction of the first portion in a direction away from the first portion. The limiting portion is also in the shape of an elongated strip, and one end of the limiting portion extends in a radial direction of the opening in a direction away from the opening.

[0015] In some embodiments, the plurality of second portions are evenly spaced along the circumference of the first portion. The plurality of stoppers are evenly spaced along the circumference of the opening.

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

[0017] On the other hand, an embodiment of the present application provides a display device, including a display panel, a back plate, a diffusion plate, and any of the above-mentioned light panels. The display panel has a display surface and a back surface arranged opposite to the current market surface. The back plate is located on the side where the back of the display panel is located, and forms a mounting cavity with the display panel. The light panel is arranged in the accommodating cavity and connected to the back plate. The support member is located on the side of the substrate close to the display panel. The diffusion plate is located on the side of the light panel close to the display panel, and abuts against the support member.

[0018] Since the display device provided in the embodiment of the present application includes any of the above-mentioned lamp boards, it can solve the same technical problems as the above-mentioned lamp boards and achieve the same technical effects, which will not be repeated here.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In the description of the present application, it should be understood that the terms, "up", "down", "left", "right", "front", "back", "inside", "outside", "center", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

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

[0039] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0040] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0041] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0042] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0043] As people's living standards improve, display devices have become essential household appliances for daily use. Display devices generally include display panels. The display panel can be a self-luminous display panel, or a display panel that requires an external light source to provide light.

[0044] For a display device whose display panel cannot emit light by itself, the display device may include a backlight module and a display panel. According to the different positions of the backlight sources in the backlight module, the backlight module may be divided into a direct-type backlight module and an edge-type backlight module.

[0045] For a display device with a direct backlight module, the backlight module may include a light board and a diffusion board. The light board is arranged opposite to the display panel and is used to provide light for the display panel. The diffusion board is located between the light board and the display panel and is used to diffuse the light emitted by the light board.

[0046] In the related art, in order to support and fix the diffusion plate, a diffusion plate bracket is generally provided on the light board. Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a light board 010 and a diffuser bracket 011 in the related art. Figure 2 The front view of a diffuser bracket 011 installed on a lamp board 010 in the related art, the lamp board 010 includes a substrate 012 and a light source 013. The diffuser bracket 011 is located on a side of the substrate 012 close to the light source 013 and is fixedly connected to the substrate 012.

[0047] In the right Figure 1 and Figure 2 When the light panel 010 with the diffuser bracket 011 is packaged and transported, Figure 3 As shown, Figure 3 This is a structural diagram of a plurality of light panels 010 equipped with diffuser plate brackets 011 packaged in a packaging box 014. Since the diffuser plate brackets 011 are relatively high and there is a relatively large gap between two adjacent substrates 012, the number of light panels 010 that can be placed in a single packaging box 014 is reduced, and the packaging and transportation efficiency of the light panels 010 is relatively low.

[0048] Based on this, an embodiment of the present application provides a display device, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the overall structure of a display device 100 provided in an embodiment of the present application. The display device 100 may include a display panel 10 , a back panel 20 , and a light panel 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 ( Figure 4 The display surface is the lower surface of the display panel 10. The display surface can be used to display images. Exemplarily, the display panel 10 can be a liquid crystal display panel.

[0050] There are multiple sub-pixels distributed in the liquid crystal display panel. The sub-pixel is the smallest imaging unit of the liquid crystal display panel. Multiple adjacent sub-pixels that emit different light can constitute a pixel. For example, adjacent red (red, R) sub-pixels, green (green, G) sub-pixels, and blue (blue, B) sub-pixels constitute a pixel. In this case, the purpose of adjusting the pixel display color can be achieved by adjusting the proportion of R, G, and B light 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 forms a mounting cavity 201 with the display panel 10. The mounting cavity 201 can provide an installation space. For example, Figure 4 As shown, the back plate 20 and the display panel 10 can enclose a substantially trapezoidal mounting cavity 201 .

[0052] Continue to refer to Figure 4 The light board 30 is located in the installation cavity 201 and is used to provide light so that the display panel 10 can display images. The light board 30 can emit light toward the back of the display panel 10. After the back of the display panel 10 receives the light, the display surface can display images.

[0053] According to the different sizes of the display panel 10 and the light board 30, the display device 100 may include multiple light boards 30. The multiple light boards 30 emit light toward 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 light board 30.

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

[0055] A plurality of light sources 32 may be evenly spaced and arranged on the substrate 31. The light sources 32 may emit light for display panel 10 ( Figure 4 ) provides light. The type of light source 32 can be selected according to actual conditions. Exemplarily, the light source 32 can be a Mini-LED light-emitting chip, and the Mini-LED light-emitting chip can be fixed on the substrate 31 by glue dispensing packaging.

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

[0057] like Figure 4 As shown, the diffusion plate 40 is located on the side of the substrate 31 close to the light source 32. The light emitted by the light source 32 is diffused by the diffusion plate 40 to become more uniform, and then transmitted to the display panel 10 for image display, so that the display effect is better.

[0058] Continue to refer to Figure 4In order to support the diffusion plate 40, the light board 30 may further include a support member 33. The support member 33 is located at one side of the substrate 31 and is connected to the substrate 31. The support member 33 may be used to support the diffusion plate 40.

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

[0060] In order to reduce the space occupied by the light board 30 during transportation, the transportation efficiency of the light board 30 is improved. Figure 6 As shown, Figure 6 for Figure 5 In the partial enlarged view of the center A, a receiving cavity 331 is formed inside the support member 33. An opening communicating with the receiving cavity 331 is provided at one end of the support member 33 connected to the substrate 31. In contrast, a avoidance hole 311 is provided on the substrate 31, and the avoidance hole 311 is arranged opposite to the opening. The avoidance hole 311 can be used to allow the support member 33 of another light board 30 to pass through and extend into the receiving cavity 331.

[0061] Therefore, if Figure 7 As shown, Figure 7 The schematic diagram of the structure of the lamp board 30 provided in the embodiment of the present application when it is packaged in the packaging box 200, when multiple light boards 30 are packaged and transported, the support member 33 on one substrate 31 can pass through the avoidance hole 311 on another adjacent substrate 31, and extend into the accommodating cavity 331 inside the support member 33 on the other substrate 31.

[0062] In this way, there is an overlapping height between the support members 33 on two adjacent substrates 31, so that the distance between the two adjacent substrates 31 is reduced, so that more light panels 30 can 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 light 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 relative to the avoidance hole 311 on another 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 light boards 30 can also be placed alternately in the same packaging box 200. At this time, in order to allow the support member 33 on one substrate 31 to be arranged opposite to the avoidance hole 311 on the other adjacent substrate 31, the avoidance holes 311 on the two different specifications of the substrates 31 need to be designed according to the actual situation.

[0065] In addition, if Figure 7 As shown, when the light board 30 is packaged and transported, a plurality of light board support boxes 300 can be stacked in the packaging box 200. The light board 30 can be fixed inside the packaging box 200 by the light board support boxes 300. Thus, the light board support boxes 300 can prevent squeezing between adjacent light boards 300, ensuring that the light board 30 is not damaged during packaging and transportation.

[0066] In some embodiments, Figure 6 As shown, the support member 33 has a side wall 332. The side wall 332 is arranged around the axis of the avoidance hole 311 to form a receiving cavity 331 with an opening. One end of the side wall 332 close to the substrate 31 is arranged around the periphery of the avoidance hole 311 and is connected to the substrate 31. Thus, the support member 33 can be fixed to the periphery of the avoidance hole 311 through one end of the side wall 332 close to the substrate 31, so that the opening and the avoidance hole 311 can be arranged relative to each other.

[0067] Among them, Figure 6 As shown, along the direction perpendicular to the substrate 31 and away from the substrate 31, that is, Figure 6 In the X direction shown in , the area of ​​the outer contour of the cross section of the side wall 332 gradually decreases, and the vertical projection of the cross section of part of the side wall 332 on the surface of the side of the substrate 31 close to the support member 33 is located in the avoidance hole 311, so that the part of the side wall 332 away from the substrate 31 can pass through the avoidance hole 311. The cross section of the side wall 332 is parallel to the surface of the side of the substrate 31 close to the support member 33.

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

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

[0070] like Figure 6 As shown in FIG. 1 , the outer contour area of ​​the cross section of the side wall 332 gradually decreases along a direction perpendicular to the substrate 31 and away from the substrate 31 . Figure 6 The design of the accommodation cavity 331 inside the support member 33 shown in the figure is that the cross-sectional area inside the accommodation cavity 331 at a position in the support member 33 far from the substrate 31 is also small. In this way, when designing the support member 33, the wall thickness of the side wall 332 at each position along the direction perpendicular to the substrate 31 can be kept consistent, thereby ensuring the structural strength of the support member 33.

[0071] Of course, in other embodiments, such as Figure 8 As shown, Figure 8 A partial enlarged view of another support member 33 in another substrate 31 provided in an embodiment of the present application shows that the cross-sectional area of ​​the accommodating cavity 331 may also remain unchanged in a direction perpendicular to the substrate 31 and away from the substrate 31. At this time, the thickness of the side wall 332 near the substrate 31 is relatively thick, which can provide a better support effect.

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

[0073] In the direction perpendicular to the surface of the substrate 31 close to the support member 33, the distance between the first section S and the substrate 31 can be smaller than the distance between the first section S and the end of the support member 33 away from the substrate 31. Therefore, when two light boards 30 are stacked together, at least half of the support member 33 on one of the substrates 31 can pass through the avoidance hole 311, so that the interval between two adjacent substrates 31 is small, ensuring the packaging and transportation efficiency of the light boards 30.

[0074] It is understandable that, along the direction perpendicular to the surface of the side of the substrate 31 close to the support member 33, the relationship between the distance L1 between the first section S and the substrate 31 and the distance L2 between the first section S and the end of the support member 33 away from the substrate 31 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 section S and the substrate 31 may be greater than the distance between the first 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 avoidance hole 311 on the other substrate 31.

[0076] In some embodiments, in order to fix the support member 33, as shown in FIG. Fig. 9 As shown, Fig. 9 The schematic diagram of the structure of a substrate 31 close to the light source 32 provided in the embodiment of the present application, the light board 30 further includes a soldering pad 34. The soldering pad 34 is arranged on the surface of the light board 30 close to the support member 33. The soldering pad 34 and the support member 33 ( Figure 8 ) is welded at one end close to the lamp board 30, and the support member 33 is connected to the substrate 31 through the welding pad 34. Thus, the support member 33 can be welded to the substrate 31 through the welding pad 34, and the connection is more reliable and not easy to separate from the substrate 31.

[0077] Of course, the support member 33 may also be fixed to the substrate 31 in other ways. For example, in other embodiments, the support member 33 may also be bonded to the substrate 31. Alternatively, the support member 33 may also be connected to the substrate 31 by a snap-fit ​​structure, which may be selected according to actual conditions and is only described as an example here.

[0078] In some embodiments, Fig. 9 As shown, the avoidance hole 311 may include a first portion 3111 and a plurality of second portions 3112. The first portion 3111 is arranged opposite to the opening. The plurality of second portions 3112 are located on the circumference of the first portion 3111 and are arranged at intervals around the circumference of the first portion 3111. A pad 34 is arranged between two adjacent second portions 3112 along the circumference of the first portion 3111.

[0079] Correspondingly, such as Fig.10 As shown, Fig.10 A structural schematic diagram of a support member 33 provided in an embodiment of the present application having an open side, the support member 33 may include a main body portion 333 and a plurality of limiting portions 334 .

[0080] The main body 333 has a receiving cavity 331 formed inside. The main body 333 is close to the substrate 31 ( Fig. 9 ) has an opening connected to the accommodating cavity 331. The end of the main body 333 close to the substrate 31 is connected to the pad 34 ( Fig. 9 ) welding. Thus, the support member 33 can be welded to the substrate 31 through its main body 333. It can be understood that the main body 333 has the side wall 332 mentioned above.

[0081] like Fig.10 As shown, a plurality of limiting portions 334 are located on the main body 333 near the substrate 31 ( Fig. 9 ) is connected to the main body 333. A plurality of stoppers 334 are arranged at intervals along the circumference of the opening. A stopper 334 is clamped to a second portion 3112 ( Fig. 9 )Inside.

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

[0083] In addition, since the limiting portion 334 is located in the second part 3112, the limiting portion 334 can interact with the substrate 31, so that the main body 333 is not easy to move relative to the substrate 31, thereby ensuring the firmness and stability of the connection between the main body 333 and the substrate 31.

[0084] Of course, in other embodiments, such as Fig.11 As shown, Fig.11 This is a schematic diagram of another structure of a substrate 31 close to a light source 32 provided in an embodiment of the present application, wherein the avoidance hole 311 may also only include the first portion 3111. Fig.12 As shown, Fig.12 Another structural diagram of the support member 33 provided in the embodiment of the present application has an open side, and the support member 33 may also include only the main body 333. At this time, during installation, the main body 333 and the pad 34 are directly welded to complete the installation and fixation of the support member 33 on the substrate 31.

[0085] In some embodiments, Fig. 9 As shown, the second part 3112 is in the shape of a long strip. One end of the second part 3112 is connected to the first part 3111, and the other end extends in the radial direction of the first part 3111 in a direction away from the first part 3111. Based on this, when making the avoidance hole 311, it can be made directly, which is more convenient.

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

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

[0088] Correspondingly, such as Fig.14 As shown, Fig.14 A structural diagram of another support member 33 provided in an embodiment of the present application having an opening on one side, in order to allow the stopper 334 to smoothly extend into the second portion 3112 of the avoidance hole 311, a gap may be provided between one end of the stopper 334 close to the opening and the edge of the opening along the radial direction of the opening. Thus, when the support member 33 is installed, the stopper 334 may smoothly extend into the second portion 3112 of the avoidance hole 311.

[0089] In some embodiments, Fig. 9 As shown, the plurality of second portions 3112 are evenly spaced along the circumference of the first portion 3111. Fig.10 As shown, a plurality of limiting portions 334 are evenly spaced along the circumference of the opening. Thus, when the plurality of limiting portions 334 are respectively located in the plurality of second portions 3112, the movement of the support member 33 can be limited from various positions, ensuring that the support member 33 can be firmly mounted and fixed on the substrate 31.

[0090] In some embodiments, Fig. 9 As shown, the number of the second parts 3112 is an even number, and the number of the second parts 3112 is greater than two, and the extension of the plurality of second parts 3112 passes through the axis of the first part 3111, and is symmetrically arranged 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 symmetrically arranged in pairs about the axis of the first part 3111, the structure of the avoidance hole 311 is relatively simple, and it is more convenient to manufacture.

[0091] Correspondingly, such as Fig.10 As shown, the number of the limiting portions 334 is also an even number, and the number of the 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 is symmetrically arranged in pairs about the axis of the opening. Similarly, the structure and position setting of the plurality of limiting portions 334 are also relatively simple, which facilitates the production of the support member 33. Of course, in other embodiments, the number of the second portion 3112 can also be an odd number. Accordingly, the number of the limiting portions 334 is consistent with the number of the second portion 3112.

[0092] It is understandable that the number of the second part 3112 can be designed according to actual conditions. Fig. 9 As shown, the number of the second parts 3112 can be four, and the four second parts 3112 are symmetrically arranged in pairs about the axis of the first part 3111, and along the circumference of the first part 3111, the angle between two adjacent second parts 3112 is 90°. Of course, the number of the second parts 3112 can also be six, eight, etc. The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
