Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a connection structure and an electronic device. Background Technology

[0002] As consumers increasingly demand thin and portable electronic devices, these devices are becoming smaller and thinner. Consequently, the connection structures formed by the interconnection of components within these devices also need to be reduced in size and thickness.

[0003] In related technologies, there is a method of connecting two components using screws. However, due to limitations in component thickness, the length of the matching screws must be shortened, resulting in a very limited number of screw threads and unstable connections between components. When electronic devices are subjected to external forces such as vibration or impact, the screws are prone to loosening or falling off, affecting the connection's stability. Furthermore, the screw installation process requires precise alignment and tool operation, which is not only cumbersome but also time-consuming, reducing installation efficiency.

[0004] To address the aforementioned issues, the relevant technologies urgently need improvement. Utility Model Content

[0005] This application provides a connection structure and an electronic device to at least solve the aforementioned problems in the related art.

[0006] To achieve the above objectives, this application provides the following technical solution: a connection structure, comprising: a first main body portion, wherein a snap-fit ​​groove is provided on the first main body portion, and a guide opening is provided on the groove wall of the snap-fit ​​groove; a second main body portion, wherein a snap-fit ​​member is provided on the second main body portion, the snap-fit ​​member being able to enter the snap-fit ​​groove along the guide opening and forming a snap-fit ​​connection with the snap-fit ​​groove; and a stop member, wherein the stop member protrudes from the second main body portion and contacts the first main body portion, and in the state of connection between the first main body portion and the second main body portion, prevents the snap-fit ​​member from disengaging from the snap-fit ​​groove along the guide opening.

[0007] Furthermore, this application also proposes that a mounting hole is provided on the first main body, the mounting hole penetrates the first main body, and the second main body is embedded in the mounting hole when the first main body is connected to the second main body.

[0008] Furthermore, this application also proposes that the first main body is provided with a limiting channel, which is disposed opposite to the snap-fit ​​groove. The limiting channel extends in a direction perpendicular to the axial direction of the snap-fit ​​groove and communicates with the mounting hole. The second main body is provided with a plug at one end away from the snap-fit ​​member. When the first main body and the second main body are connected, the plug is inserted into the limiting channel to limit the displacement of the second main body relative to the first main body in the axial direction of the snap-fit ​​groove.

[0009] Furthermore, this application also proposes that the first main body is provided with an elastic member, the first end of which is fixed to the end of the first main body away from the snap-fit ​​groove, and the other end of which is in contact with the side of the second main body near the plug-in member. The elastic member drives the second main body to press against the top wall of the limiting channel by the released elastic force.

[0010] Furthermore, this application also proposes that the snap-fit ​​component is a snap-fit ​​shaft, and the snap-fit ​​component is rotatably connected to the snap-fit ​​groove.

[0011] Furthermore, this application also proposes that the stop is a spring sheet, the first end of which is fixedly connected to the second main body. When the first main body and the second main body are connected, the second end of the spring sheet contacts the side of the first main body that is away from the guide opening. The elastic force released by the spring sheet is transmitted through the first main body so that the groove wall of the snap-fit ​​groove abuts against the snap-fit ​​member.

[0012] Furthermore, this application also proposes that the number of snap-fit ​​components and snap-fit ​​slots are the same and there are multiple snap-fit ​​components, which are arranged at intervals along the axial direction of the snap-fit ​​slots, and each snap-fit ​​component forms a snap-fit ​​connection with a corresponding snap-fit ​​slot.

[0013] Furthermore, this application also proposes that at least one of the plurality of snap-fit ​​members is provided with a first protrusion and at least one of the plurality of snap-fit ​​members is provided with a second protrusion. When the first body part and the second body part are connected, the first protrusion contacts the first end of the corresponding snap-fit ​​groove and the second protrusion contacts the second end of the corresponding snap-fit ​​groove, so as to restrict the snap-fit ​​member from displacement relative to the first body part in the axial direction of the snap-fit ​​groove.

[0014] Furthermore, this application also proposes that there be multiple stops, with each stop located between two adjacent snap-fit ​​members.

[0015] Furthermore, this application also proposes an electronic device including the aforementioned connection structure.

[0016] In the aforementioned connection structure, when the snap-fit ​​component enters the snap-fit ​​groove along the guide opening and forms a snap-fit ​​connection with the snap-fit ​​groove, the stop component prevents the snap-fit ​​component from detaching from the snap-fit ​​groove along the guide opening. This prevents the first main body and the second main body from separating from each other when the connection structure is subjected to vibration or impact, thereby improving the robustness of the connection structure. At the same time, the guide opening guides the snap-fit ​​component smoothly into the snap-fit ​​groove, making the operation convenient, quick, and labor-saving, thus improving the assembly efficiency of the connection structure. In this way, after the snap-fit ​​component is guided into the snap-fit ​​groove through the guide opening and forms a snap-fit ​​connection with the snap-fit ​​groove, the stop component prevents the snap-fit ​​component from detaching from the snap-fit ​​groove along the guide opening, thereby improving the robustness of the connection structure and the assembly efficiency.

[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The embodiments described above in this application will be described in detail below with reference to the accompanying drawings.

[0031] In related technologies, the connection structure formed by connecting two components with screws has limitations. Due to the thickness of the components, the length of the matching screws must be shortened, resulting in a very limited number of screw threads and making the connection between components unstable. When electronic devices are subjected to external forces such as vibration or impact, the screws are prone to loosening or falling off, affecting the firmness of the connection. In addition, the screw installation process requires precise alignment and tool operation, which is not only cumbersome but also time-consuming, reducing installation efficiency.

[0032] To address the aforementioned issues, the first consideration was to eliminate reliance on threaded connections by employing a non-rotational assembly structure. Analysis of the feasibility of a snap-fit ​​structure revealed that a linear push-in snap-fit ​​simplifies installation, but the issue of accidental snap-fit ​​disengagement needs to be addressed. Further research showed that adding a blocking structure along the snap-fit ​​path can create a secondary locking mechanism. Combining a guide structure with limiting components achieves both rapid assembly and improved connection reliability.

[0033] This application proposes a connection structure, which includes a first main body portion 1 and a second main body portion 2. Please refer to... Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the first main body 1 in an embodiment of this application is shown. Figure 2 It shows Figure 1 Enlarged view of part II; the first main body 1 is provided with a snap-fit ​​groove 3, and a guide opening is provided on the groove wall of the snap-fit ​​groove 3. Please refer to... Figure 3 , Figure 3A schematic diagram of the structure of the second main body 2 in this embodiment is shown. The second main body 2 is provided with a snap-fit ​​member 4, which can enter the snap-fit ​​groove 3 along the guide opening and form a snap-fit ​​connection with the snap-fit ​​groove 3. A stop member 5 protrudes from the second main body 2 and contacts the first main body 1. When the first main body 1 and the second main body 2 are connected, it prevents the snap-fit ​​member 4 from disengaging from the snap-fit ​​groove 3 along the guide opening. For example, the first main body 1 can be the C-side of a laptop computer casing, and correspondingly, the second main body 2 is a touchpad assembly.

[0034] In the above-described connection structure, when the snap-fit ​​component 4 enters the snap-fit ​​groove 3 along the guide opening and forms a snap-fit ​​connection with the snap-fit ​​groove 3, the stop component 5 can prevent the snap-fit ​​component 4 from detaching from the snap-fit ​​groove 3 along the guide opening. This prevents the first main body 1 and the second main body 2 from detaching from each other when the connection structure is subjected to vibration or impact, thereby improving the robustness of the connection structure. At the same time, the guide opening can guide the snap-fit ​​component 4 to smoothly enter the snap-fit ​​groove 3, making the operation convenient, quick, time-saving, and labor-saving, thereby improving the assembly efficiency of the connection structure. Thus, after the snap-fit ​​component 4 is guided into the snap-fit ​​groove 3 through the guide opening and forms a snap-fit ​​connection with the snap-fit ​​groove 3, the stop component 5 prevents the snap-fit ​​component 4 from detaching from the snap-fit ​​groove 3 along the guide opening, thereby improving the robustness and assembly efficiency of the connection structure.

[0035] Please combine Figure 2 In some embodiments, a mounting hole 101 is provided on the first main body 1, the mounting hole 101 penetrates the first main body 1, and the second main body 2 is embedded in the mounting hole 101 when the first main body 1 is connected to the second main body 2.

[0036] Thus, the mounting hole 101 is designed to completely penetrate the first main body 1, allowing the second main body 2 to be inserted into the hole axially. When the two main bodies are connected, the outer surface of the second main body 2 forms a surface contact with the inner wall of the mounting hole 101, forming an overlapping structure rather than a superimposed structure in the thickness direction. Since there is no need to set additional screw holes and thread structures, the thickness of the connection part is compressed to the thickness range of a single main body, thereby reducing the space occupied by the connection structure in the thickness direction.

[0037] It is understood that the mounting hole 101 refers to a through-hole structure that penetrates the thickness of the first main body 1. Specifically, it can be achieved by stamping or mechanical drilling, and the second main body 2 is embedded in the hole to form a nested fit. Here, "embedded" means that the outer contour of the second main body 2 forms a contact fit with the inner wall of the mounting hole 101, which can be achieved by interference fit or clearance fit, and the embedded part is constrained and limited in the horizontal direction by the hole wall.

[0038] In some embodiments, please combine Figure 4 and Figure 5 , Figure 4 An exploded view of the connection structure in this embodiment is shown. Figure 5 It shows Figure 4 Enlarged view of part V in the middle; the first main body 1 is also provided with a limiting channel 102, which is disposed opposite to the snap-fit ​​groove 3. The limiting channel 102 extends in a direction perpendicular to the axial direction of the snap-fit ​​groove 3 and communicates with the mounting hole 101; the second main body 2 is provided with a plug 6 at one end away from the snap-fit ​​member 4. When the first main body 1 and the second main body 2 are connected, the plug 6 is inserted into the limiting channel 102 to limit the displacement of the second main body 2 relative to the first main body 1 in the axial direction of the snap-fit ​​groove 3.

[0039] Thus, when the second main body 2 is inserted into the first main body 1 through the mounting hole 101, the connector 6 enters the limiting channel 102 in a direction perpendicular to the axial direction of the snap-fit ​​groove 3. The width of the limiting channel 102 in the axial direction of the snap-fit ​​groove 3 is the same as the dimension of the connector 6 in that direction, so that the connector 6 forms a contact constraint with the sidewall of the limiting channel 102, thereby preventing the second main body 2 from moving along the axial direction of the snap-fit ​​groove 3. At the same time, the snap-fit ​​connection of the connector 4 in the snap-fit ​​groove 3 provides radial constraint, and the cooperation between the limiting channel 102 and the connector 6 forms axial constraint. The two cooperate to improve the stability between the first main body 1 and the second main body 2.

[0040] Preferably, the connector 6 can be a columnar protrusion integrally formed with the second main body 2. The width of the connector 6 along the limiting channel 102 in the axial direction of the snap-fit ​​groove 3 is the same as the dimension of the connector 6 in that direction. The thickness of the limiting channel 102 is greater than the thickness of the connector 6, so as to provide the snap-fit ​​4 of the second main body 2 with a space for movement when snapping.

[0041] Please combine Figure 2 In some embodiments, the first main body 1 is further provided with an elastic member 7. The first end of the elastic member 7 is fixed to the end of the first main body 1 away from the snap-fit ​​groove 3, and the other end of the elastic member 7 is in contact with the side of the second main body 2 near the plug 6. The elastic member 7 drives the second main body 2 to press against the top wall of the limiting channel 102 by the released elastic force.

[0042] Thus, after the second main body 2 completes the assembly of the connector 6 and the limiting channel 102, the elastic member 7 continuously applies elastic force to the second main body 2 due to the pre-compression state generated by the installation position. This elastic force drives the surface of the connector 6 of the second main body to abut against the top wall of the limiting channel 102 along the thickness direction, so as to limit the connector 6 in the thickness direction of the limiting channel 102, thereby further improving the stability between the second main body 2 and the first main body 1.

[0043] Preferably, the elastic element 7 refers to a mechanical element capable of elastic deformation and generating a continuous force through compression or pre-stretching. For example, the elastic element 7 can be a spring sheet or a rubber block.

[0044] Preferably, the method of fixing the first end of the elastic member 7 to the end of the first main body 1 away from the snap-fit ​​groove 3 is not limited. For example, it can be fixed by welding; or by screws; or by snap-fit.

[0045] Please combine Figure 3 In some embodiments, the snap-fit ​​component 4 is a snap-fit ​​shaft, and the snap-fit ​​component 4 is rotatably connected to the snap-fit ​​groove 3.

[0046] Thus, a rotatable connection is achieved through the locking shaft and the locking groove 3, so that the second main body 2 can adjust its angle through the locking shaft. At the same time, when the electronic device is subjected to an external impact, it can absorb energy through the damping friction between the locking shaft and the locking groove 3, thereby offsetting part of the impact force.

[0047] It is understandable that the groove wall of the snap-fit ​​groove 3 has a certain elastic deformation capacity. When the snap-fit ​​shaft enters the guide opening, the groove wall of the snap-fit ​​groove 3 deforms and expands the guide opening, allowing the snap-fit ​​shaft to be smoothly snapped in. When the snap-fit ​​shaft is snapped into the snap-fit ​​groove 3, the guide opening returns to its original size, thereby realizing the snap-fit ​​of the snap-fit ​​shaft. At the same time, the groove wall of the snap-fit ​​groove 3 squeezes the snap-fit ​​shaft. When the snap-fit ​​shaft rotates relative to the snap-fit ​​groove 3, it can generate damping friction force.

[0048] Please combine Figure 3 In some embodiments, the stop 5 is a spring sheet. The first end of the spring sheet is fixedly connected to the second main body 2. When the first main body 1 and the second main body 2 are connected, the second end of the spring sheet contacts the side of the first main body 1 that is away from the guide opening. The elastic force released by the spring sheet is transmitted through the first main body 1 so that the groove wall of the snap-fit ​​groove 3 abuts against the snap-fit ​​member 4.

[0049] Thus, after the spring is fixed to the second main body 2, its free end is unrestrained. When the second main body 2 is assembled with the first main body 1, the free end of the spring is pressed by the surface of the first main body 1, forcing the spring to bend and deform. The elastic force generated by the bending deformation is transmitted to the groove wall of the snap-fit ​​groove 3, causing the groove wall to continuously press against the surface of the snap-fit ​​part 4, thereby improving the firmness between the first main body 1 and the second main body 2.

[0050] Preferably, the spring is a thin metal sheet with bending deformation capability. For example, the spring can be made of spring steel or phosphor bronze.

[0051] Preferably, the method of fixing the first end of the spring piece to the second main body 2 is not limited; for example, the first end of the spring piece to the second main body 2 is fixed by integral molding; or, the first end of the spring piece to the second main body 2 is fixed by welding; or, the first end of the spring piece to the second main body 2 is fixed by riveting.

[0052] Please combine Figure 2 and Figure 3 In some embodiments, the number of snap-fit ​​pieces 4 and snap-fit ​​slots 3 are the same and there are multiple snap-fit ​​pieces 4. The multiple snap-fit ​​pieces 4 are arranged at intervals along the axial direction of the snap-fit ​​slots 3, and each snap-fit ​​piece 4 forms a snap-fit ​​connection with a corresponding snap-fit ​​slot 3.

[0053] Thus, during assembly, the snap-fit ​​component 4 of the second main body 2 enters the snap-fit ​​groove 3 of the first main body 1 along the guide opening, and multiple snap-fit ​​components 4 form segmented snap-fit ​​with the corresponding snap-fit ​​groove 3. Each snap-fit ​​component 4 independently bears the local load, so that the overall load-bearing capacity of the connection structure is distributed to multiple snap-fit ​​points, reducing the risk of breakage due to overload at a single snap-fit ​​point, thereby further improving the connection stability.

[0054] Please combine Figure 3 In some embodiments, at least one of the multiple snap-fit ​​members 4 is provided with a first protrusion 8, and at least one of the multiple snap-fit ​​members 4 is provided with a second protrusion 9. When the first main body 1 and the second main body 2 are connected, the first protrusion 8 contacts the first end of the corresponding snap-fit ​​groove 3, and the second protrusion 9 contacts the second end of the corresponding snap-fit ​​groove 3, so as to restrict the snap-fit ​​member 4 from displacement relative to the first main body 1 in the axial direction of the snap-fit ​​groove 3.

[0055] Thus, the contact between the first protrusion 8 and the first end of the locking groove 3 forms a positive displacement constraint, while the contact between the second protrusion 9 and the second end of the locking groove 3 forms a negative displacement constraint. By providing the first protrusion 8 and the second protrusion 9 on different locking members 4 respectively, the axial displacement of each locking member 4 is limited by the protrusions on the adjacent locking members 4. For example, when an external impact causes the second main body 2 to tend to move axially, the contact surface between the first protrusion 8 and the end of the locking groove 3 generates a reverse force, while the second protrusion 9 generates a reverse constraint at the end of another locking groove 3, thereby eliminating the displacement gap in both directions.

[0056] Furthermore, if the number of snap-fit ​​pieces 4 is N, and the number of first protrusions 8 is N1, then 1 ≤ N1 ≤ N; and the number of second protrusions 9 is N2, then 1 ≤ N2 ≤ N; where N, N1, and N2 are all integers. For example, if the number of snap-fit ​​pieces is 3, then the number of first protrusions can be 1, 2, or 3, and the number of second protrusions can be 1, 2, or 3.

[0057] Please combine Figure 3 In some embodiments, there are multiple stop members 5, with each stop member 5 located between two adjacent snap-fit ​​members 4.

[0058] Thus, by setting an independent stop 5 in the gap between every two adjacent snap-fit ​​pieces 4, each stop 5 can simultaneously apply a blocking force to the snap-fit ​​pieces 4 on both sides. When an external force attempts to disengage the snap-fit ​​piece 4 along the guide opening, the stop 5 located in the gap simultaneously restricts the displacement tendency of the snap-fit ​​pieces 4 on both sides through the reaction force generated by contact with the first main body 1. This multi-point distribution method ensures that both sides of each snap-fit ​​piece 4 are covered by adjacent stop 5, avoiding the defect that a single stop 5 cannot effectively restrain the distal snap-fit ​​piece 4 due to its large span.

[0059] This application also proposes an electronic device including the aforementioned connection structure. For example, the electronic device can be a laptop computer, where the first main body 1 is the C-side of the laptop computer casing, and the second main body 2 is a touchpad assembly.

[0060] Thus, the above-mentioned connection structure makes the electronic devices more efficient to assemble, further optimizes the spatial structure, and facilitates the production of smaller electronic devices, thereby meeting the market's demand for compact and lightweight electronic products.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
