DETAILED DESCRIPTION

[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0035] The technical solution of the embodiment of the present disclosure is to solve the above technical problems, and the overall idea is as follows:

[0036] Example 1

[0037] Reference Figure 1 and attached Figure 2 , an electronic device provided by an embodiment of the present disclosure includes a mounting plate 1, a first structural part 2 and a second structural part 3; the mounting plate 1 can be used to carry and conduct electronic components (not shown in the figure); the first structural part 2 includes a first cylinder 21 and a first limiting part 22, the first cylinder 21 has an internal thread, which is used to cooperate with a screw or other parts with a screw structure to screw the mounting plate 1 to fix the position between the first structural part 2 and the mounting plate 1; the first limiting part 22 is arranged at one end of the first cylinder 21, and the radial size of the first limiting part 22 is different from the radial size of the first cylinder 21, so as to form a first step surface 23 between the first cylinder 21 and the first limiting part 22, and the first step surface 23 is used to fit and connect the first surface 11 of the mounting plate 1; the second structural part 3 is connected to the first limiting part 22, so as to limit the movement of the first step surface 23 relative to the first surface 11 when the first cylinder 21 is subjected to a twisting force.

[0038] Specifically, in order to solve the problem that the connection strength is low when the screw column is welded on one side of the existing PCB, which affects the subsequent installation and product quality, the electronic device provided in this embodiment is provided with a first limiting portion 22 at one end of the first cylinder 21, so that it can cooperate with the second structural portion 3 to achieve the limitation of the first cylinder 21 when the mounting plate 1 is screwed, and avoid the relative movement between the first step surface 23 and the first surface 11 of the mounting plate 1, thereby ensuring the screw connection stability between the first structural portion 2 and the mounting plate 1, and avoiding the first structural portion 2 from falling off the mounting plate 1 when the first cylinder 21 is screwed to the screw or other components with a screw structure.

[0039] Among them, the electronic device provided in this embodiment can be but is not limited to any electronic device with a shell, such as a mobile phone, a tablet computer, a laptop computer, a display screen, etc., and the cooperation between the first structural part 2, the second structural part 3 and the mounting plate 1 can achieve the cooperation installation with the positioning hole of the shell of the electronic device.

[0040] Among them, the mounting plate 1 can be but is not limited to a PCB board, on which electronic components, wiring, etc. can be arranged; the mounting plate 1 is provided with mounting holes 12, which are used to lock with screws or screws to achieve a locking connection between the housing of the electronic device and the mounting plate 1, thereby ensuring the assembly of the electronic device.

[0041] Among them, the first structural part 2 is a rigid structure, which includes a first cylinder 21 and a first limiting part 22. The first cylinder 21 has an internal thread to cooperate with a screw column or a screw to realize a screw connection with the mounting plate 1. The first limiting part 22 can be, but is not limited to, a cylindrical structure, which can be a complete cylindrical structure or a partial cylindrical structure to ensure the penetration of the screw or the screw. During installation, the first limiting part 22 needs to be inserted into the mounting hole 12 of the mounting plate 1, and can be partially penetrated or completely penetrated to ensure the stability of the connection between the first structural part 2 and the mounting plate 1. In this embodiment, The radial dimension of the first limiting portion 22 is set to be smaller than or larger than the diameter of the first cylinder 21, so that a transitional first step surface 23 is formed at the connection between the first cylinder 21 and the first limiting portion 22. When the first limiting portion 22 is inserted into the mounting hole 12, the first step surface 23 fits with the first surface 11 of the mounting plate 1. In actual installation, the first surface 11 and the first step surface 23 can be bonded to further improve the connection stability between the first structural portion 2 and the mounting plate 1, and ensure the stability of the first structural portion 2 when the screw or bolt is screwed and locked with the first structural portion 2.

[0042] Among them, the second structural part 3 is a rigid structure, and the second structural part 3 is connected to the first limiting part 22, which can be snap-connected, bonded, screwed, etc., to ensure the stability of the first limiting part 22 and prevent the first limiting part 22 from rotating when the first cylinder 21 is screwed; in this embodiment, the second structural part 2 can be formed by the mounting hole 12, or it can be formed by providing an additional limiting device on the side of the mounting plate 1 away from the first cylinder 21.

[0043] According to the above, the electronic device provided in the first aspect of the present application, through the cooperation of the first structural part 2 and the second structural part 3, when the first cylinder 21 is screwed together with the screw, the first step surface 23 will not have relative movement with the first surface 11 of the mounting plate 1, thereby increasing the connection strength between the first cylinder 21 and the mounting plate 1, and ensuring that the screw will not fall off the mounting plate 1 when installed in cooperation with the first structural part 2; thereby solving the problem of low connection strength when single-sided welding of screw columns on the existing PCB affects subsequent installation and product quality.

[0044] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0045] Further, see Attachment Figure 2In the electronic device provided in this embodiment, in a specific implementation, a mounting hole 12 is provided on the mounting plate 1 to form the second structural portion 3, and at least a portion of the inner wall of the mounting hole 12 abuts against and limits at least a portion of the outer wall of the first limiting portion 22 to limit the rotation of the first limiting portion 22.

[0046] Specifically, in this embodiment, the mounting hole 12 is used as the second structural part 3, so that the inner wall of the mounting hole 12 and the outer wall of the first limiting part 22 form an interference fit to prevent the first limiting part 22 from rotating in the mounting hole 12; for example: the first limiting part 22 can be set as a prismatic cylinder, and the mounting hole 12 can be set as a circular hole or a polygonal hole; the first limiting part 22 can be set as a cylindrical cylinder, and the mounting hole 12 can be set as a non-circular hole or a circular hole; as long as the interference fit of the first limiting part 22 in the mounting hole 12 is ensured, it will be sufficient.

[0047] Further, see Attachment Figure 7 In the electronic device provided in this embodiment, in a specific implementation, the mounting plate 1 is provided with a mounting hole 12; the second structural portion 3 has a second step surface 31, and when the first structural portion 2 and the second structural portion 3 are connected through the mounting hole 12, the second step surface 31 is used to fit and connect the second surface 13 of the mounting plate 1 opposite to the first surface 11.

[0048] Specifically, in this embodiment, the second structural part 3 can also be set as an additional limiting structure, and the second structural part 3 is connected to the first structural part 2 on the second surface 13 side of the mounting plate 1 to limit the rotation of the first cylinder 21 relative to the mounting plate 1; specifically, the second structural part 3 has a second step surface 31, and when the second structural part 3 is connected to the first structural part 2 through the mounting hole 12 and the first limiting part 22, the second step surface 31 fits with the second surface 13 of the mounting plate 1. In this embodiment, the two can also be designed to be bonded to each other, so as to further improve the connection stability between the first structural part 2, the second structural part 3 and the mounting plate 1, ensure the stability of the first cylinder 21 when being screwed, and avoid relative rotation with the mounting plate 1.

[0049] Further, see Attachment Figure 3 In the electronic device provided in this embodiment, in a specific implementation, the second structural portion 3 includes a second cylinder 32 and a second limiting portion 33; the second cylinder 32 has an internal thread for threaded connection with the first cylinder 21; the second limiting portion 33 is arranged at one end of the second cylinder 32, and the second limiting portion 33 is used to insert the mounting hole 12 to connect the first limiting portion 22, and the radial dimension of the second limiting portion 33 is different from the radial dimension of the second cylinder 32, so as to form the second step surface 31 between the second cylinder 32 and the second limiting portion 33.

[0050] Specifically, in order to form the second step surface 31 and realize the connection between the second structural part 3 and the first limiting part 22, in this embodiment, the second structural part 3 is configured to include a second cylinder 32 and a second limiting part 33. The structure of the second cylinder 32 refers to the structure of the first cylinder 21 mentioned above, so that the screw or screw passes through the mounting plate 1 and simultaneously connects the first cylinder 21 and the second cylinder 32 to ensure the locking state with the mounting plate 1; the structure of the second limiting part 33 can also refer to the structure of the first limiting part 22 mentioned above, and the second limiting part 33 can be inserted into the mounting hole 12 and connected to the first limiting part 22 and The first limiting portion 22 is limited; accordingly, the radial dimension of the second limiting portion 33 is smaller than or larger than the diameter of the second cylinder 32, thereby forming a second step surface 31 to fit the second surface 13 of the mounting plate 1, that is, when the first structural portion 2 and the second structural portion 3 are connected, the first surface 11 and the second surface 13 of the mounting plate 1 are clamped and connected by the first step surface 23 and the second step surface 31 at the same time; the second step surface 31 and the mounting plate 1 can also be bonded to ensure that the second structural portion 3 and the mounting plate 1 do not move relative to each other, further increasing the stability of the first structural portion 2 when subjected to a twisting force. In this embodiment, the thickness of the second structural portion 3 in the first direction a can be set to be smaller than the thickness of the first structural portion 2 in the first direction a, so as to be suitable for equipment with a small installation space, which is helpful for the design of ultra-thin equipment.

[0051] Furthermore, in the electronic device provided in this embodiment, in a specific implementation, the first limiting portion 22 and the second limiting portion 33 are both cylinders, and at least part of the cylinder walls of the first limiting portion 22 and the second limiting portion 33 are in contact with and connected to each other.

[0052] Specifically, in order to achieve the mutual connection and limitation of the first limiting part 22 and the second limiting part 33, in this embodiment, both of them can be set as a cylindrical structure, which can be but not limited to a circular cylinder. The two can be connected and limited by mutual socketing, mutual threading, and mutual engagement.

[0053] For example, the first method: refer to the attached Figure 4 The first limiting portion 22 is sleeved on the outside of the second limiting portion 33 , and the inner wall of the first limiting portion 22 is closely connected to the outer wall of the second limiting portion 33 .

[0054] Specifically, the first limiting portion 22 is sleeved outside the second limiting portion 33, and the second limiting portion 33 can be completely sleeved in the axial direction, or only the portion corresponding to the mounting hole 12 can be sleeved, and the cylinder walls of the two can be but not limited to being bonded. Of course, the second limiting portion 33 can be sleeved outside the first limiting portion 22, and the inner wall of the second limiting portion 33 is attached to and connected to the outer wall of the first limiting portion 22.

[0055] For example, in the second mode, the first limiting portion 22 has a first internal thread, and the second limiting portion 33 has an external thread matched with the first internal thread, so that the first limiting portion 22 and the second limiting portion 33 are screwed together. Specifically, the first limiting portion 22 and the second limiting portion 33 are screwed together, and on this basis, a colloid can be provided on the screwed surface to further improve the connection stability and prevent the first cylinder 21 from being detached when being screwed.

[0056] For example, the third method: refer to the attached Figure 5 and attached Figure 6 , the first limiting portion 22 includes a plurality of first teeth 24 spaced around the first direction a; the first direction a is the axial direction of the first cylinder 21; the second limiting portion 33 includes a plurality of second teeth 34 spaced around the first direction a; wherein, an accommodation space adapted to the first teeth 24 is formed between adjacent second teeth 34, so that the first limiting portion 22 and the second limiting portion 33 can mesh with each other. Specifically, through the meshing of the first teeth 24 and the second teeth 34, the second limiting portion 33 and the first limiting portion 22 cannot rotate relative to each other, and then when the first step surface 23 and the second step surface 31 are fixedly attached, no matter how the first cylinder 21 is screwed, it will not rotate relative to the mounting plate 1, which greatly improves the installation stability of the first structural portion 2 relative to the mounting plate 1 and prevents it from falling off. It can be understood that the structural dimensions of the first teeth 24 and the second teeth 34 can be the same or different, as long as they can be matched and meshed, and the dimensions of the two in the first direction a can be the same or different. It is also easy to understand that the first tooth portion 24 and the second tooth portion 34 can be pointed teeth or polygonal teeth, the first tooth portion 24 can be arranged around the first direction a, can be arranged partially, or can be arranged intermittently, and the second tooth portion 34 can be arranged accordingly.

[0057] Furthermore, the electronic device provided in this embodiment, in a specific implementation, also includes a shell (not shown in the figure) and a screw column (not shown in the figure), and the shell is provided with a positioning hole (not shown in the figure); the screw column passes through the positioning hole and is screwed to the first structural part 2 to connect the shell to the mounting plate 1.

[0058] Specifically, when assembling the shell, the first structural part 2 and the second structural part 3 can be used to pass the screw column or screw through the positioning hole of the shell and then screw and lock it with the first structural part 2 to achieve a stable connection between the shell and the mounting plate 1, and there will be no problem of falling off or loosening during installation and use.

[0059] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in 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.
