Description

Technical Field

[0001] The present application relates to the technical field of fastening connections, and particularly to a fixing component and an electronic device. Background Art

[0002] In the mechanical and related fields, the fastening connection between two components is usually achieved by using threaded fasteners such as screws and bolts. However, the threaded fasteners in the traditional technology require the assistance of tools such as wrenches and screwdrivers during connection and installation, which is inconvenient to operate. Utility Model Content

[0003] Based on this, in view of the problem of inconvenient operation of the fastening connection components in the traditional technology, it is necessary to provide a fixing component and an electronic device.

[0004] On the one hand, the present application provides a fixing component, which includes a first connecting piece and a second connecting piece. The first connecting piece includes a first disc portion and a hollow first rod portion. The first disc portion is connected to the outer periphery of one end of the first rod portion, and the other end of the first rod portion is provided with an external thread. The second connecting piece includes a second disc portion and a hollow second rod portion. The second disc portion is connected to the outer periphery of one end of the second rod portion, and the other end of the second rod portion is provided with an internal thread. Wherein, the external thread is screwed with the internal thread, the first disc portion and the second disc portion face each other to clamp the piece to be fixed, and the inner cavity of the first rod portion is communicated with the inner cavity of the second rod portion for the operating portion to penetrate into and drive the first rod portion and the second rod portion to rotate relatively.

[0005] In one embodiment, the inner cavity of the first rod portion is a first inner cavity. One end of the first inner cavity far from the second connecting piece is provided with a first guiding hole communicated with the outside. Along the axial direction of the first rod portion from outside to inside, the size of the first guiding hole gradually decreases.

[0006] In one embodiment, the inner cavity of the second rod portion is a second inner cavity. The first rod portion is inserted into the second inner cavity. The internal thread is provided on the cavity wall of the second inner cavity, and there is a gap between the internal thread and the end face of the second rod portion close to the first connecting piece to form a positioning hole for the first rod portion to penetrate into the second inner cavity.

[0007] In one embodiment, one end of the second inner cavity far from the first connecting piece is provided with a second guiding hole communicated with the outside. Along the axial direction of the second rod portion from outside to inside, the size of the second guiding hole gradually decreases.

[0008] In one embodiment, the inner diameter of the first inner cavity is the same as the inner diameter of the second inner cavity.

[0009] In one embodiment, the outer circumferential surfaces of the first rod portion and the second rod portion are located on the same cylindrical surface.

[0010] In one embodiment, the fixing assembly further includes a retaining disc. The first connecting member and the second connecting member are configured to pass through the mounting hole. The retaining disc is connected to a side of the first disc portion facing away from the second disc portion, and an outer diameter of the retaining disc is larger than that of the first disc portion for shielding a gap between the first disc portion and a hole wall of the mounting hole.

[0011] In one embodiment, a convex ring is protrudingly provided on a side of the first disc portion facing away from the second disc portion, and the retaining disc is sleeved on the convex ring.

[0012] In one embodiment, a mating portion is provided in the inner cavity of the first rod portion and / or the inner cavity of the second rod portion. The mating portion is configured to be driven by the operating portion to drive the first rod portion and / or the second rod portion to rotate.

[0013] On the other hand, the present application further provides an electronic device. The electronic device includes a to-be-fixed member and the fixing assembly as described above. The fixing assembly passes through at least two of the to-be-fixed members to relatively fix at least two of the to-be-fixed members.

[0014] In the above fixing assembly, after the external thread and the internal thread are screwed together, the first disc portion and the second disc portion can clamp the to-be-fixed member in an opposite direction to achieve a fastening connection. Moreover, the inner cavities of the first rod portion and the second rod portion are communicated for the operating portion to penetrate. Compared with the prior art in which the end of a screw or a bolt is interactively operated to drive the bolt and the screw to rotate, the inner cavities of the first rod portion and the second rod portion in the fixing assembly provided by the present application are mutually communicated. Therefore, there is sufficient operating space for contact interaction, so it is possible to conveniently drive the first rod portion and the second rod portion to rotate relative to each other without relying on tools, thereby realizing installation and disassembly. For example, the operating portion can be an operator's finger. Since there is sufficient contact surface in the inner cavities of the first rod portion and the second rod portion for contacting with the finger, the first rod portion and the second rod portion can be driven to rotate relative to each other by inserting the finger into the inner cavities of the first rod portion and the second rod portion, and the operation is convenient.

Detailed implementation manners

[0022] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0023] In the description of the present application, it should be understood that if there appear such terms as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application.

[0024] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] In this application, unless otherwise clearly specified and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In this application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0028] Please refer to Figure 1 , Figure 1 , which shows a cross-sectional view of the electronic device 10 provided by an embodiment of this application in one direction. The electronic device 10 includes a fixing component 100 and a to-be-fixed component 200, and the number of the to-be-fixed components 200 is at least two. The fixing component 100 passes through at least two to-be-fixed components 200 to relatively fix at least two to-be-fixed components 200, realizing a fastening connection.

[0029] In each embodiment, the number of the parts to be fixed 200 is taken as two for illustration. For the convenience of understanding and description, one of the parts to be fixed 200 is denoted as the first part to be fixed 210, and the other part to be fixed 200 is denoted as the second part to be fixed 220. For example, the first part to be fixed 210 and the second part to be fixed 220 can be the front cover and the rear cover of the electronic device 10 respectively. The front cover and the rear cover are connected and fixed by passing the fixing component 100 through the front cover and the rear cover. The fixing component 100 has the effect of facilitating installation and disassembly. Therefore, when the electronic device 10 needs to be overhauled or there are other situations where the front cover and the rear cover need to be disassembled, the fixing component 100 can be conveniently operated to achieve disassembly.

[0030] Please refer to Figures 2 to 5 As shown in, a fixing component 100 provided in an embodiment of the present application includes a first connecting member 110 and a second connecting member 120. The first connecting member 110 includes a first disc portion 111 and a first rod portion 112. The first rod portion 112 is provided with a hollow interior. The first disc portion 111 is connected to the outer periphery of one end of the first rod portion 112, and an external thread 113 is provided at the other end of the first rod portion 112. The second connecting member 120 includes a second disc portion 121 and a second rod portion 122. The second rod portion 122 is provided with a hollow interior. The second disc portion 121 is connected to the outer periphery of one end of the second rod portion 122, and an internal thread 123 is provided at the other end of the second rod portion 122. Wherein, the external thread 113 is screwed with the internal thread 123, the first disc portion 111 and the second disc portion 121 face each other to clamp the part to be fixed 200, and the inner cavities of the first rod portion 112 and the second rod portion 122 are communicated for the operation portion to penetrate into and drive the first rod portion 112 and the second rod portion 122 to rotate relative to each other.

[0031] In the above fixing component 100, after the external thread 113 is screwed with the internal thread 123, the first disc portion 111 and the second disc portion 121 can face each other to clamp the part to be fixed 200 to achieve a firm connection. Moreover, the inner cavities of the first rod portion 112 and the second rod portion 122 are communicated for the operation portion to penetrate into. Compared with the prior art in which the end of a screw or a bolt is interactively operated to drive the bolt and the screw to rotate, the inner cavities of the first rod portion 112 and the second rod portion 122 in the fixing component 100 provided in the present application are mutually communicated. Therefore, there is sufficient operating space for contact interaction, so it is possible to conveniently drive the first rod portion 112 and the second rod portion 122 to rotate relative to each other without relying on tools, and installation and disassembly can be achieved. For example, the operation portion can be the finger of the operator. Since there is sufficient contact surface in the inner cavities of the first rod portion 112 and the second rod portion 122 for contacting the finger, the first rod portion 112 and the second rod portion 122 can be driven to rotate relative to each other by inserting the finger into the inner cavities of the first rod portion 112 and the second rod portion 122. Without relying on tools, the operation is convenient.

[0032] Please refer to Figure 1, it should be noted that since the first rod portion 112 is provided with an external thread 113 on its outer side, and the second rod portion 122 is provided with an internal thread 123 on its inner side, the first rod portion 112 and the second rod portion 122 are inserted into each other so that the internal thread 123 and the external thread 113 can be screwed together. And as Figure 1 shown, when the internal thread 123 and the external thread 113 cooperate, they are sleeved and cover each other, so that the threads do not contact the workpiece 200 to be fixed, reducing the risk of the workpiece 200 being scratched by the threads.

[0033] Please refer to Figure 1 , both the first workpiece 210 to be fixed and the second workpiece 220 to be fixed are provided with mounting holes 230, and the mounting holes 230 of the two are docked with each other. The fixing assembly 100 is inserted through the mounting holes 230 to fasten and connect the first workpiece 210 to be fixed and the second workpiece 220 to be fixed. In one embodiment, the outer circumferential surface of the first rod portion 112 and the outer circumferential surface of the second rod portion 122 are located on the same cylindrical surface. In this way, the outer surface is more regular after the first rod portion 112 and the second rod portion 122 are connected, reducing the possible damage to the workpiece 200 to be fixed.

[0034] Furthermore, the outer diameter of the first rod portion 112 can be configured to be the same as the outer diameter of the second rod portion 122, so that the outer circumferential surface of the first rod portion 112 and the outer circumferential surface of the second rod portion 122 are located on the same cylindrical surface.

[0035] Please refer to Figure 5 , in one embodiment, the inner cavity of the first rod portion 112 is the first inner cavity 114, and one end of the first inner cavity 114 away from the second connecting member 120 is provided with a first guiding hole 115 communicating with the outside. Along the axis O1 direction of the first rod portion 112 from outside to inside, the size of the first guiding hole 115 gradually decreases. With such a setting, on the one hand, it is convenient to guide the operating portion to be inserted into the first inner cavity 114. On the other hand, since the size of the first guiding hole 115 gradually decreases from outside to inside, the first guiding hole 115 has an inclined or arc-shaped inner wall, which can not only reduce the possible damage to the operating portion (still taking a finger as an example), but also allow the operating portion to extend into the first inner cavity 114 in a bent posture, facilitating the operation.

[0036] Please refer to Figure 4, in one embodiment, the inner cavity of the second rod portion 122 is the second inner cavity 124. One end of the second inner cavity 124 away from the first connecting member 110 is provided with a second inlet hole 125 communicating with the outside. Along the axis O2 direction of the second rod portion 122 from outside to inside, the size of the second inlet hole 125 gradually decreases. Similar to the first inlet hole 115, the size of the second inlet hole 125 gradually decreases from outside to inside, which is convenient for guiding the insertion of the operating portion, allows the operating portion to drive the relative rotation of the second rod portion 122 and the first rod portion 112 in a bent posture, and reduces the possible damage to the operating portion.

[0037] It should be noted that since the inner side of the second rod portion 122 is provided with an internal thread 123, in the case of the same axial length, the inner cavity of the first rod portion 112 can have a larger contact area with the operating portion. Therefore, generally, the installation and disassembly can be realized by actively driving the rotation of the first rod portion 112. However, in this application, both the first rod portion 112 and the second rod portion 122 are hollow and the operating portion can extend into them. Therefore, in each embodiment of this application, it is not limited which of the first rod portion 112 and the second rod portion 122 rotates actively to realize the installation and disassembly, and it can be flexibly selected according to actual operation needs.

[0038] Please refer to again Figure 1 , in one embodiment, the inner diameter of the first inner cavity 114 is the same as the inner diameter of the second inner cavity 124. Therefore, the operating portion can be flexibly configured to penetrate into the first inner cavity 114 or the second inner cavity 124 according to requirements. Further, the inner circumferential surface of the first inner cavity 114 and the inner circumferential surface of the second inner cavity 124 can also be located on the same cylindrical surface.

[0039] Please refer to Figure 1 and Figure 4In one embodiment, the first rod portion 112 is plugged into the second inner cavity 124. The internal thread 123 is provided on the cavity wall of the second inner cavity 124, and there is a gap between the internal thread 123 and the end face of the second rod portion 122 close to the first connector 110 to form a positioning hole 126. The positioning hole 126 is provided for the first rod portion 112 to penetrate into the second inner cavity 124, so when the first rod portion 112 and the second rod portion 122 are plugged, the positioning hole 126 can provide positioning for the first rod portion 112, so as to facilitate the insertion of the first rod portion 112 into the second inner cavity 124. It can be understood that the first rod portion 112 penetrates into the second inner cavity 124 so that the internal thread 123 is screwed into the external thread 113. According to the characteristics of the threaded connection, the internal thread 123 and the external thread 113 are smoothly connected and matched, requiring the first rod portion 112 and the second rod portion 122 to be plugged in a substantially coaxial posture. However, the insertion point of the first rod 112 and the second rod 122 is located inside the first fixture 210 and the second fixture 220, which is difficult to observe. Therefore, the second rod 122 provided in this embodiment has a reserved positioning hole 126. When the first rod 112 and the second rod 122 are plugged together, the positioning hole 126 can perform preliminary positioning on the first rod 112, so as to facilitate adjusting the first rod 112 to a coaxial posture with the second rod 122, thereby improving the smoothness of the cooperation between the internal thread 123 and the external thread 113.

[0040] See also Figure 1 In one embodiment, the fixing assembly 100 further includes a baffle 130. The first connecting member 110 and the second connecting member 120 are used to be inserted into the mounting hole 230. The baffle 130 is connected to the side of the first disk portion 111 away from the second disk portion 121, and the outer diameter of the baffle 130 is larger than the first disk portion 111, and is used to block the gap between the first disk portion 111 and the hole wall of the mounting hole 230. Through the shielding effect of the baffle 130, the probability of dust and debris entering the gap between the first disk portion 111 and the hole wall of the mounting hole 230 can be reduced, and the negative impact of dust and debris on the smoothness of rotation of the first rod portion 112 can be reduced. The baffle 130 can also be set at the second disk portion 121 to reduce the probability of dust and debris entering the gap between the second disk portion 121 and the hole wall of the mounting hole 230.

[0041] like Figure 4 and Figure 6 Furthermore, a convex ring 116 is protruded from one side of the first disc portion 111 away from the second disc portion 121 , and the baffle plate 130 is sleeved on the convex ring 116 . The convex ring 116 can position the installation of the baffle plate 130 .

[0042] In one embodiment, a mating portion (not shown in the figures, the same hereinafter) is provided in the inner cavity of the first rod portion 112 and / or the inner cavity of the second rod portion 122. The mating portion is configured to be driven by the operating portion to drive the first rod portion 112 and / or the second rod portion 122 to rotate. By adding the mating portion, it is convenient for the operating portion to drive the first rod portion 112 and / or the second rod portion 122 to rotate. For example, the mating portion may be a rib, a bump, or other structures that can improve the contact effect and protrude from the inner wall of the inner cavity of the first rod portion 112 and / or the second rod portion 122.

[0043] It should be noted that the present application is not limited to the operating portion being configured only as the operator's finger. In cases where necessary, the operating portion may also be a rod-shaped tool, and the first rod portion 112 and the second rod portion 122 are driven to rotate relative to each other by inserting the operating portion into the inner cavities of the first rod portion 112 and the second rod portion 122. It can be understood that, compared with screws and bolts in the prior art, when the operating portion is inserted into the inner cavities of the first rod portion 112 and the second rod portion 122, it can have a larger contact area with the first rod portion 112 and the second rod portion 122, which is convenient for driving the first rod portion 112 and the second rod portion 122 to rotate relative to each other.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0045] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
