Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to a mid-frame and an electronic device. Background Technology

[0002] In existing technologies, when structural components and electronic parts in electronic devices mate with the mid-frame, slots are provided on the inner sidewall of the mid-frame to restrict these components. Since the structural components and electronic parts are generally spaced horizontally, the slots on the inner sidewall of the mid-frame are also offset horizontally to effectively limit their movement. In this method, the structural components and electronic parts occupy a large amount of horizontal space within the mid-frame, resulting in an excessively large horizontal dimension for the electronic device. Furthermore, the offset placement of the slots on the mid-frame to restrict the structural components and electronic parts also affects the assembly of the electronic device.

[0003] Therefore, there is an urgent need for a new electronic device that can limit the movement of structural components and electronic elements, and also reduce the space occupied by structural components and electronic elements in the horizontal direction. Utility Model Content

[0004] This application provides a mid-frame and an electronic device that can limit the position of a first component and a second component while also reducing the space occupied by the first component and the second component on the horizontal plane.

[0005] In a first aspect, this application provides an electronic device comprising a mid-frame, a first component, and a second component. The mid-frame has a receiving cavity, in which both the first component and the second component are disposed, and are stacked along a first direction. A first limiting groove and a second limiting groove are provided on the inner wall of the mid-frame, arranged along the first direction, and both communicating with the receiving cavity. The first limiting groove restricts movement of the first component along the first direction, and the second limiting groove restricts movement of the second component along the first direction, where the first direction is the thickness direction of the electronic device.

[0006] In this embodiment of the electronic device, the first component and the second component are stacked along the thickness direction of the electronic device. Compared to the first and second components being arranged on a horizontal plane, this reduces the space occupied by the first and second components in the horizontal plane, allowing more components to be arranged in the receiving cavity. It also reduces the horizontal dimensions of the electronic device. Furthermore, since the first and second components are stacked along a first direction, the first and second limiting grooves can also be arranged along the first direction, allowing for the limiting of the first and second components in that direction. The first and second limiting grooves do not need to be staggered on the inner wall of the middle frame, simplifying the assembly of the first and second components in the receiving cavity and also simplifying the fabrication of the first and second limiting grooves on the middle frame.

[0007] It is worth noting that the first and second components can be structural components and electronic elements in a receiver, microphone, antenna, or camera within an electronic device. The electronic device may include two mid-frames. When the electronic device includes two mid-frames, it is a foldable electronic device. The two mid-frames are connected by a folding structure, which allows them to be unfolded or folded. In this case, both mid-frames may be provided with the aforementioned receiving cavities for accommodating the first and second components. One receiving cavity is used to accommodate one of the receiver, microphone, antenna, or camera, and the other receiving cavity is used to accommodate one of the receiver, microphone, antenna, or camera. The electronic device may also include only one mid-frame.

[0008] In one embodiment, in the first direction, the projection of the first component at least partially coincides with the top plate of the first limiting groove, and the projection of the second component at least partially coincides with the top plate of the second limiting groove. This ensures that when the first component moves along the first direction, the first limiting groove can limit the movement of the first component. When the second component moves along the first direction, the second limiting groove can limit the movement of the second component.

[0009] In one embodiment, the first limiting groove and the second limiting groove are coaxially arranged. This makes it easier for the first component and the second component to be disposed in the first limiting groove and the second limiting groove.

[0010] In one embodiment, the projection of the first limiting groove completely covers the second limiting groove in the first direction. This ensures that the first component moves within a set range when it moves along the first direction.

[0011] In one embodiment, the middle frame includes a first border, a second border, and a third border. The first border and the third border are arranged parallel to each other, and the second border connects the ends of the first border and the third border on the same side. A first limiting groove and a second limiting groove are disposed on the side of the first border near the second border, and the first limiting groove and the second limiting groove are arranged on the first border along a first direction. Whether the first limiting groove and the second limiting groove are specifically disposed on the first border or the second border can be adjusted according to the layout requirements of the internal components of the middle frame.

[0012] In one embodiment, the middle frame includes a first border, a second border, and a third border. The first border and the third border are arranged parallel to each other, and the second border connects the ends of the first border and the third border on the same side. A first limiting groove and a second limiting groove can be disposed on the side of the second border near the first border, and the first limiting groove and the second limiting groove are arranged on the second border along a first direction. The first limiting groove includes a first sub-limiting groove and a second sub-limiting groove. The first sub-limiting groove is disposed on the side of the first border near the second border, and the second sub-limiting groove is disposed on the side of the second border near the first border, and the first sub-limiting groove and the second sub-limiting groove are interconnected. The second limiting groove includes a third sub-limiting groove and a fourth sub-limiting groove. The third sub-limiting groove is disposed on the side of the first border near the second border, and the fourth sub-limiting groove is disposed on the side of the second border near the first border, and the third sub-limiting groove and the fourth sub-limiting groove are interconnected. In this method, the first sub-limiting groove on the first frame and the second sub-limiting groove on the second frame form the first limiting groove. Compared to setting the first limiting groove separately on the first or second frame, this can increase the strength of the first or second frame. The third sub-limiting groove on the second frame and the fourth sub-limiting groove on the second frame form the second limiting groove. Compared to setting the second limiting groove separately on the first or second frame, this can also increase the strength of the first or second frame.

[0013] In the above embodiments, the second border can be set perpendicular to the first border and the third border.

[0014] In one embodiment, a first opening is provided on the top plate of the first limiting groove, the first opening being used to connect the first limiting groove and the second limiting groove. The first opening prevents the top plate of the first limiting groove from interfering with the first component and the second component when they are engaged with the first and second limiting grooves.

[0015] In one embodiment, in the first direction, the distance between the first component and the top plate of the first limiting groove is 0-0.2 mm; this ensures that the first component can more easily cooperate with the first limiting groove and also ensures that the first component has room to move in the first direction. The distance between the second component and the top plate of the second limiting groove is 0-0.2 mm. This ensures that the second component can more easily cooperate with the second limiting groove and also ensures that the second component has room to move in the first direction.

[0016] In one embodiment, the length of the overlapping portion between the top plate of the first limiting groove and the first component is 0.2–0.5 mm, which ensures that the top plate of the first limiting groove can limit the first component in a first direction. Similarly, the length of the overlapping portion between the top plate of the second limiting groove and the second component is 0.2–0.5 mm, which also ensures that the top plate of the second limiting groove can limit the second component in a first direction.

[0017] In one embodiment, the distance between the first component and the sidewall of the first limiting groove is 0.1 to 1 mm, which ensures that the first component will not interfere with the sidewall of the first limiting groove. Similarly, the distance between the second component and the sidewall of the second limiting groove is 0.1 to 1 mm, which also ensures that the second component will not interfere with the sidewall of the second limiting groove.

[0018] In one embodiment, in the first direction, the height of the first limiting groove is 1-2 mm, and the height of the second limiting groove is 1-2 mm.

[0019] Secondly, this application provides a mid-frame having a receiving cavity for accommodating a first component and a second component, the first component and the second component being stacked along a first direction; a first limiting groove and a second limiting groove are provided on the inner wall of the mid-frame, the first limiting groove and the second limiting groove being arranged along the first direction and communicating with the receiving cavity, wherein: the first limiting groove is used to restrict the movement of the first component along the first direction, the second limiting groove is used to restrict the movement of the second component along the first direction, and the first direction is the thickness direction of the first component or the second component.

[0020] In this embodiment, the sidewall of the middle frame has a first limiting groove and a second limiting groove arranged along a first direction. The first limiting groove is used to limit the first component, and the second limiting groove is used to limit the second component. Since the first and second limiting grooves are arranged along the first direction, and the first and second components are stacked along the first direction, the space occupied by the first and second components in the horizontal plane of the middle frame's receiving cavity is relatively small. In addition, since the first and second limiting grooves are arranged along the first direction, it is not necessary to misalign the first and second limiting grooves on the middle frame, which simplifies the fabrication of the middle frame.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0034] Electronic devices typically include a flexible display screen, a mid-frame, and multiple components housed within the mid-frame. These components may include: a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a receiver, a microphone, an antenna, or a camera. The receiver, microphone, antenna, or camera all comprise structural components and electronic elements. The mid-frame has a cavity for accommodating these components. When the structural components and electronic elements are positioned within the cavity, slots are provided on the sidewalls of the cavity to restrict their movement along a first direction, where the first direction is the thickness direction of the flexible display screen. The structural components and electronic elements generally overlap at least partially in their projections along the first direction. Therefore, the slots used to restrict the structural components and electronic elements need to be offset on the sidewalls of the cavity to ensure proper installation. However, this method results in a large internal space occupied by the structural components and electronic elements within the mid-frame in a plane perpendicular to the first direction, leading to an excessively large horizontal dimension of the electronic device. Furthermore, the misalignment of the slots used to restrict structural components and electronic parts on the mid-frame can affect the assembly of electronic devices.

[0035] Therefore, there is an urgent need for a new electronic device to solve the above problems.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

(Refer to...) Figure 1 and Figure 2 The electronic device 1 provided in this application embodiment can specifically be a smartphone, smartwatch, tablet computer, or laptop computer, etc. Specifically, the electronic device 1 is a foldable electronic device 1, such as a foldable phone or foldable tablet computer. The electronic device 1 can also be a candybar-style phone or tablet computer.

[0040] Continue to refer to Figure 1 The electronic device 1 may include two mid-frames 10 and a flexible display screen 20. The two mid-frames 10 are connected by a folding mechanism, and the two mid-frames 10 can be unfolded or folded relative to each other through the folding mechanism. The flexible display screen 20 is disposed on the two mid-frames 10. Specifically, the flexible display screen 20 can be bonded to the two mid-frames 10 by adhesive bonding.

Wherein, Figure 3 In this context, the X direction can be understood as the horizontal direction, the Y direction as the vertical direction, and the Z direction as the height direction. The plane formed by the X and Y directions is the horizontal plane. The X direction can also be understood as the length direction of the electronic device, the Y direction as the width direction, and the Z direction as the thickness (height) direction. The first direction below is... Figure 3 In the Z-direction, the horizontal plane is the plane formed by the X and Y directions. (Refer to...) Figures 1-10 The middle frame 10 has a receiving cavity 14, which can be used to accommodate a first component 30 and a second component 40. The first component 30 and the second component 40 are stacked along a first direction. A first limiting groove 15 and a second limiting groove 16 are provided on the inner wall of the middle frame 10. The first limiting groove 15 and the second limiting groove 16 are arranged along the first direction, and both the first limiting groove 15 and the second limiting groove 16 are in communication with the receiving cavity 14. The first direction is the thickness direction of the electronic device 1. The first component 30 and the second component 40 are stacked along the first direction, and the second component 40 can be used to press the first component 30. In addition, this arrangement can reduce the space occupied by the first component 30 and the second component 40 on the horizontal plane, so that more components can be placed in the receiving cavity 14, and can also reduce the size of the electronic device 1 in the X and Y directions. When the first limiting groove 15 and the second limiting groove 16 are provided on the inner wall of the middle frame 10, the first limiting groove 15 and the second limiting groove 16 do not need to be misaligned, which can simplify the difficulty of setting the first limiting groove 15 and the second limiting groove 16. Moreover, the first limiting groove 15 and the second limiting groove 16 can be stacked in the same position, which simplifies the assembly difficulty of the electronic device 1.

[0043] It is worth mentioning that the first component 30 and the second component 40 can be, but are not limited to, structural components or electronic elements in the receiver, microphone, antenna, or camera of the electronic device 1. Specifically, the second component 40 can be a flexible circuit board. Since the flexible circuit board has a smaller thickness along the first direction, stacking the second component 40 with the first component 30 results in a larger reduction in the size of the electronic device 1 in the X and Y directions, while the increase in the thickness of the electronic device 1 is relatively small. Alternatively, the first component 30 can also be a flexible circuit board.

[0044] In some other embodiments, the first component 30 and the second component 40 can also be a single integral component. In this case, the first component 30 and the second component 40 are two parts of the integral component, and the first limiting groove 15 and the second limiting groove 16 respectively limit the two different parts of the integral component to improve the stability of the integral component in the receiving cavity. The number of the first component 30 and the second component 40 can also be multiple. In this case, the number of the first limiting groove 15 and the second limiting groove 16 can also be multiple to ensure that each component can be limited by the limiting groove.

[0045] Continue to refer to Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In the first direction, the projection of the first component 30 on the flexible display screen at least partially overlaps with the projection of the top plate a of the first limiting groove 15 on the flexible display screen, so that when the first component 30 moves along the first direction, the top plate a of the first limiting groove 15 can limit the distance the first component 30 moves in the first direction, allowing the first component 30 to move within a set range. Similarly, the projection of the second component 40 on the flexible display screen at least partially overlaps with the projection of the top plate b of the second limiting groove 16 on the flexible display screen, so that when the second component 40 moves along the first direction, the top plate b of the second limiting groove 16 can limit the distance the second component 40 moves along the first direction, allowing the second component 40 to move within a set range. Furthermore, when the first component 30 is a structural assembly and the second component 40 is an electronic component, the first limiting groove 15 can also prevent the first component 30 from squeezing the second component 40 during movement, reducing the probability of damage to the second component 40.

[0046] In the above embodiments, the axes of the first limiting groove 15 and the second limiting groove 16 coincide, that is, the first limiting groove 15 and the second limiting groove 16 are coaxially arranged, which facilitates the opening of the first limiting groove 15 and the second limiting groove 16 on the middle frame 10. In addition, when the first component 30 and the second component 40 are disposed in the receiving cavity 14, since the first limiting groove 15 and the second limiting groove 16 are coaxially arranged, it is only necessary to mate a portion of the first component 30 and a portion of the electronic component 40 with the first limiting groove 15 and the second limiting groove 16. It is not necessary to first place the first component 30 in its corresponding slot and then place the second component 40 in its corresponding slot. The first component 30 and the second component 40 can be assembled on the outside of the middle frame 10 and then installed on the middle frame 10, thereby simplifying the assembly process of the electronic device 1.

[0047] Continue to refer to Figures 4 to 10The middle frame 10 includes a first border 11, a second border 12, and a third border 13. The first border 11 and the third border 13 are arranged parallel to each other. The second border 12 connects the ends of the first border 11 and the third border 13 located on the same side. The second border 12 can be arranged perpendicular to both the first border 11 and the third border 13. In one embodiment, the first limiting groove 15 can be provided on the side of the first border 11 near the second border 12, and the second limiting groove 16 can also be provided on the side of the first border 11 near the second border 12. This can be understood as the first limiting groove 15 and the second limiting groove 16 being provided at the connection between the first border 11 and the second border 12, and both the first limiting groove 15 and the second limiting groove 16 being provided on the first border 11. In this way, the provision of the first limiting groove 15 and the second limiting groove 16 will not affect the arrangement of other components within the electronic device, nor will it affect the provision of mounting parts such as slots for installing other components. In the Y direction, the portion of the first limiting groove 15 that overlaps with the first component 30 is 4-5 mm, ensuring that the overlapping portion of the first limiting groove 15 and the first component 30 can limit the movement of the first component 30 along the first direction. Furthermore, in the Y direction, the gap between the first component 30 and the sidewall of the first limiting groove 15 is 0.5-1 mm, and in the X direction, the gap d2 between the first component 30 and the sidewall of the first limiting groove 15 is 0.1-0.2 mm, making it easier for the first component 30 to be installed in the first limiting groove 15. When the first component 30 is installed in the first limiting groove 15, the actual overlap between the first component 30 and the top plate a of the first limiting groove 15 in the first direction is 0.2 to 0.5 mm. If the overlap between the first component 30 and the top plate a of the first limiting groove 15 is greater than 0.5 mm, the first component 30 may abut against the side wall of the first limiting groove 15 in the Y direction, affecting the installation of the first component 30. If the overlap between the first component 30 and the top plate a of the first limiting groove 15 is less than 0.2 mm, the limiting effect of the first limiting groove 15 in the Y direction will be reduced.

[0048] When the second limiting groove 16 limits the second component 40, in the Y direction, the portion of the second limiting groove 16 that overlaps with the second component 40 is 4-5 mm, ensuring that the overlapping portion of the second limiting groove 16 and the second component 40 can effectively limit the second component 40 when it moves along the first direction. Furthermore, in the Y direction, the gap between the second component 40 and the sidewall of the second limiting groove 16 is 0.5-1 mm. In the X direction, the gap d1 between the second component 40 and the sidewall of the second limiting groove 16 is 0.1-0.2 mm, making it easier for the second component 40 to be installed in the second limiting groove 16. When the second component 40 is installed in the second limiting groove 16, the actual overlap between the second component 40 and the top plate b of the second limiting groove 16 in the first direction is 0.2 to 0.5 mm. If the overlap between the second component 40 and the top plate b of the second limiting groove 16 is greater than 0.5 mm, the second component 40 may abut against the side wall of the second limiting groove 16 in the Y direction, affecting the installation of the second component 40. If the overlap between the second component 40 and the top plate b of the second limiting groove 16 is less than 0.2 mm, the limiting effect of the second limiting groove 16 on the second component 40 in the Y direction will be reduced.

[0049] It is worth mentioning that, in the X direction, the length of the top plate of the first limiting groove 15 is greater than the length of the bottom wall of the second limiting groove 16, so as to ensure that the size of the first limiting groove 15 is greater than the size of the second limiting groove 16. In the projection in the first direction, that is, the projection of the first limiting groove 15 on the horizontal plane completely covers the projection of the second limiting groove 16 on the horizontal plane, so as to ensure that the first component 30 will not enter the second limiting groove 16 when moving along the first direction.

[0050] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10In some other embodiments, the first limiting groove 15 may include a first sub-limiting groove 110 and a second sub-limiting groove 120. The first sub-limiting groove 110 is disposed on the side of the first side frame 11 near the second side frame 12, and the second sub-limiting groove 120 is disposed on the side of the second side frame 12 near the first side frame 11. The first sub-limiting groove 110 and the second sub-limiting groove 120 are interconnected. The second limiting groove 16 includes a third sub-limiting groove 111 and a fourth sub-limiting groove 121. The third sub-limiting groove 111 is disposed on the side of the first side frame 11 near the second side frame 12, and the fourth sub-limiting groove 121 is disposed on the side of the second side frame 12 near the first side frame 11. The third sub-limiting groove 111 and the fourth sub-limiting groove 121 are interconnected. The first sub-limiting groove 110 and the third sub-limiting groove 111 are coaxially arranged, and the second sub-limiting groove 120 and the fourth sub-limiting groove 121 are coaxially arranged. The first sub-limiting groove 110 is used to limit the movement of a portion of the first component 30 in the Y direction along the first direction, and the second sub-limiting groove 120 is used to limit the movement of a portion of the first component 30 in the X direction along the first direction. Thus, compared to separately providing the first limiting groove 15 and the second limiting groove 16 on the first frame 11 or the second frame 12, the dimensions of the first sub-limiting groove 110 and the third sub-limiting groove 111 on the first frame 11 and the second sub-limiting groove 120 and the fourth sub-limiting groove 121 on the second frame 12 are relatively small, which can increase the strength of the first frame 11 or the second frame 12. In the Y direction, the portion of the first sub-limiting groove 110 that overlaps with the first component 30 is 4-5 mm, ensuring that the first sub-limiting groove 110 can effectively limit the movement of the first component 30 when it moves along the first direction. In the X direction, the portion of the second sub-limiting groove 120 that overlaps with the first component 30 is 1–2.5 mm, ensuring that the second sub-limiting groove 120 can limit the movement of the first component 30 along the first direction. In the Y direction, the distance between the first component 30 and the sidewall of the first sub-limiting groove 110 is 0.5–1 mm, ensuring that the first component 30 can be more easily installed in the first sub-limiting groove 110. In the X direction, the distance between the first component 30 and the sidewall of the second sub-limiting groove 120 is 0.1 to 0.2 mm. When the first component 30 is installed in the first sub-limiting groove 110 and the second sub-limiting groove 120, the actual overlap between the top plate of the first component 30 and the first sub-limiting groove 110 in the first direction is 0.2 to 0.5 mm. If the actual overlap between the top plate of the first component 30 and the first sub-limiting groove 110 is greater than 0.5 mm, in the Y direction, the first component 30 may abut against the sidewall of the first sub-limiting groove 110.If the actual overlap between the top plate of the first component 30 and the second sub-limiting groove 120 is greater than 0.5mm, in the X direction, the first component 30 may abut against the side wall of the second sub-limiting groove 120, affecting the installation of the first component 30. If the actual overlap between the top plate of the first component 30 and the first sub-limiting groove 110 is less than 0.2mm, in the Y direction, the limiting effect of the first sub-limiting groove will be reduced. If the actual overlap between the top plate of the first component 30 and the second sub-limiting groove 120 is less than 0.2mm, in the X direction, the limiting effect of the second sub-limiting groove 120 will also be reduced.

[0051] The third sub-limiting groove 111 is used to limit the movement of a portion of the second component 40 in the Y direction along the first direction, and the fourth sub-limiting groove 121 is used to limit the movement of a portion of the second component 40 in the X direction along the first direction. Thus, the arrangement of the third sub-limiting groove 111 and the fourth sub-limiting groove 121 enables the second limiting groove 16 to limit the first component 30 in both the X and Y directions, improving the limiting effect of the first limiting groove 15 on the first component 30. In the Y direction, the portion of the first sub-limiting groove 110 that overlaps with the second component 40 is 4-5 mm, ensuring that the third sub-limiting groove 111 can effectively limit the second component 40 when it moves along the first direction. In the X direction, the portion of the second sub-limiting groove 120 that overlaps with the first component 30 is 1-2.5 mm, ensuring that the fourth sub-limiting groove 121 can effectively limit the second component 40 when it moves along the first direction. In the Y direction, the distance between the second component 40 and the sidewall of the third sub-limiting groove 111 is 0.5–1 mm. This ensures that the second component 40 is more easily installed in the third sub-limiting groove 111. In the X direction, the distance between the second component 40 and the sidewall of the fourth sub-limiting groove 121 is 0.1–0.2 mm. When the second component 40 is installed in both the third and fourth sub-limiting grooves 111 and 121, the actual overlap between the top plate of the second component 40 and the top plate of the third sub-limiting groove 111 in the first direction is 0.2–0.5 mm, and the actual overlap between the top plate of the second component 40 and the top plate of the fourth sub-limiting groove 121 in the first direction is 0.2–0.5 mm. If the actual overlap between the top plate of the second component 40 and the third sub-limiting groove 111 is greater than 0.5 mm, the second component 40 may abut against the sidewall of the third sub-limiting groove 111 in the Y direction. If the actual overlap between the second component 40 and the top plate of the fourth sub-limiting groove 121 is greater than 0.5mm, in the X direction, the second component 40 may abut against the side wall of the fourth sub-limiting groove 121, affecting the installation of the second component 40. If the actual overlap between the second component 40 and the top plate of the third sub-limiting groove 111 is less than 0.2mm, in the Y direction, the limiting effect of the third sub-limiting groove 111 will be reduced. If the actual overlap between the second component 40 and the top plate of the fourth sub-limiting groove 121 is less than 0.2mm, in the X direction, the limiting effect of the fourth sub-limiting groove 121 will also be reduced.

[0052] In some other embodiments, the first limiting groove 15 can be disposed on the side of the second frame 12 near the first frame 11, and the second limiting groove 16 can also be disposed on the side of the second frame 12 near the first frame 11. This can be understood as the first limiting groove 15 and the second limiting groove 16 being disposed at the connection between the first frame 11 and the second frame 12, and both the first limiting groove 15 and the second limiting groove 16 being disposed on the second frame 12. In this way, the placement of the first limiting groove 15 and the second limiting groove 16 will not affect the arrangement of other components within the electronic device, nor will it affect the placement of mounting portions such as slots for mounting other components. It is worth mentioning that the first limiting groove 15 and the second limiting groove 16 can also be disposed at other positions on the second frame 12, as long as the second frame 12 forms the sidewall of the aforementioned receiving cavity 14.

[0053] Continue to refer to Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In the above embodiment, in the first direction, the gap c1 between the top plate a of the first limiting groove 15 and the first component 30 is 0-0.2 mm. The gap c2 between the top plate of the second limiting groove 16 and the second component 40 is 0-0.2 mm. The gap c1 ensures that when the first component 30 is placed in the first limiting groove 15, the first component 30 can move a certain distance in the first direction, making it easier for the first component 30 to be placed in the first limiting groove 15. Similarly, the gap c2 ensures that when the second component 40 is placed in the second limiting groove 16, the second component 40 can move a certain distance in the first direction, making it easier for the second component 40 to be placed in the second limiting groove 16.

[0054] A first opening 150 is provided on the top plate a of the first limiting groove 15. The first opening 150 is used to connect the first limiting groove 15 and the second limiting groove 16. This ensures that when the first component 30 and the second component 40 are respectively located in the first limiting groove 15 and the second limiting groove 16, the top plate a of the first limiting groove 15 will not interfere with the first component 30 and the second component 40.

[0055] In the above embodiments, the height of the first limiting groove 15 and the second limiting groove 16 along the first direction is 1-2 mm. When other components are provided in the receiving cavity 14, these components can also be provided on the side of the second component 40 away from the first component 30 in the first direction, and a third limiting groove is provided on the inner sidewall of the middle frame 10. The third limiting groove is provided on the side of the second limiting groove 16 away from the first limiting groove 15, and the third limiting groove can be coaxially arranged with the second limiting groove 16. Other structures can also be provided on the side of the component away from the second component 40, as long as the height of the receiving cavity 14 allows it in the first direction. The projection of the first limiting groove 15 and the second limiting groove 16 on the horizontal plane can be arc-shaped, semi-circular, or L-shaped, etc.
