Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0002] With the widespread use of electronic devices and continuous technological advancements, users have placed higher demands on the convenience, maintainability, and lifespan of these devices. In the field of electronic device technology, the connection structure between the upper and lower housings has a significant impact on the assembly efficiency, maintainability, and user experience of the device.

[0003] In existing technologies, traditional connection methods mostly use screws or adhesives. While screws provide a secure connection, disassembly requires tools, making the process cumbersome, time-consuming, and labor-intensive. Furthermore, uneven tightening can lead to uneven stress on the housing and damage. Adhesive bonding, while achieving a seamless connection, is not removable. Repairing or replacing parts requires damaging the housing, increasing maintenance costs and difficulty, and reducing equipment maintainability. When equipment requires repair or component replacement, these two connection methods increase maintenance costs and difficulty, making it difficult to simultaneously meet users' needs for convenience and maintainability.

[0025] This utility model proposes an electronic device 1000.

[0026] Please see Figures 1 to 8 In one embodiment of the present invention, the electronic device 1000 includes an upper shell 1, a lower shell 2, and a retaining ring 3. The upper shell 1 has a limiting groove 11. The retaining ring 3 includes a body 31 and a latching part 32. The body 31 is connected to the latching part 32, and the latching part 32 is located on one side of the body 31. The latching part 32 is engaged in the limiting groove 11. The body 31 is connected to the lower shell 2.

[0027] In this embodiment, it should be noted that the electronic device 1000 includes, but is not limited to, an aerosol generating device, wearable devices, etc., and an aerosol generating device is used as an example for description. To allow for multiple appearance options in the aerosol generating device, this application uses a retaining spring 3 to enable quick installation and removal between the upper shell 1 and the lower shell 2. Combined with... Figure 3 The retaining ring 3 is a key component connecting the upper shell 1 and the lower shell 2, achieving a tight fixation between them through its own structural design. Figure 4 and Figure 7The snap-fit ​​part 32 protrudes outward from the body 31, passes through the lower shell 2, and is confined within the limiting groove 11 of the upper shell 1, thereby achieving radial positioning and limiting of the upper shell 1 and the lower shell 2. It can be understood that the shape of the snap-fit ​​part 32 is adapted to the shape of the limiting groove 11 so that the snap-fit ​​part 32 can separate from the limiting groove 11 under the action of external force. The connection between the body 31 and the lower shell 2 includes, but is not limited to, snap-fit, plug-in, and threaded connections, to achieve axial fixation of the upper shell 1 and the lower shell 2, thereby enabling relative axial movement between the two. Specifically, when the upper shell 1 needs to be replaced, only an external force needs to be applied to the upper shell 1. Under the action of the external force, the upper shell 1 moves in the disengagement direction. At this time, the snap-fit ​​part 32 of the snap-fit ​​spring 3 within the limiting groove 11 will gradually disengage from the limiting groove 11 due to friction with the inner wall of the limiting groove 11, thus achieving the separation of the upper shell 1 and the lower shell 2.

[0028] The technical solution of this utility model achieves a tight fixation between the upper shell 1 and the lower shell 2 by having the snap-fit ​​part 32 of the snap spring 3 pass through the lower shell 2 and be confined within the limiting groove 11 of the upper shell 1, and by having the body 31 of the snap spring 3 connected to the lower shell 2. This effectively prevents the upper shell 1 and the lower shell 2 from loosening or detaching due to vibration, collision, or other factors during use, thus improving the structural stability of the electronic device. Because the snap spring 3 has elasticity, the connection and disassembly of the upper shell 1 and the lower shell 2 are relatively convenient, requiring no tools to separate or fix them, reducing the assembly difficulty and maintenance cost of the electronic device. When it is necessary to replace different upper shells 1 to fit different lower shells 2, the snap spring 3 allows for separation of the upper shell 1 from the lower shell 2 simply by snapping it open. This makes it easy to replace the upper shell 1 of the electronic device within a limited space, allowing for various colors and finishes of the upper shell 1 and lower shell 2 to match different aesthetic styles.

[0029] In one embodiment of the present invention, the main body 31 further includes a mating part 33. A limiting block 21 is protruding from the inner bottom wall of the lower shell 2. A slot 21a is opened on the side of the limiting block 21 facing the mating part 33. Part of the structure of the mating part 33 is limited within the slot 21a.

[0030] In this embodiment, to enhance connection stability, the limiting block 21 and the slot 21a allow the mating part 33 to be more securely fixed to the lower shell 2, effectively preventing the retaining spring 3 from shifting or loosening during use. Figure 4 and Figure 6The limiting block 21 protrudes from the inner bottom wall of the lower shell 2. The limiting block 21 is square, and the slot 21a is provided on one side of the limiting block 21 perpendicular to the inner wall of the lower shell 2. It should be noted that the slot 21a is preferably square, and its size is adapted to the mating part 33 to limit the position of the mating part 33. In one embodiment, the limiting block 21 can also be a circular cylinder, and the slot 21a is a circular slot 21a opened radially. The guiding and symmetrical nature of the circular slot 21a is used to facilitate the quick installation and removal of the retaining spring 3. In yet another embodiment, the limiting block 21 can also be L-shaped, with the slot 21a opened on one side perpendicular to the inner bottom wall of the lower shell 2. The shape of the slot 21a is adapted to the shape of the mating part 33 to provide axial limiting and lateral support and limiting. The above configuration improves the structural strength, ensures that the mating part 33 can be accurately installed, and improves the assembly accuracy and efficiency.

[0031] In one embodiment of this utility model, the limiting block 21 has a limiting hole 21b that penetrates through the limiting block 21; the mating part 33 includes a first mating section 331 and a second mating section 332. The first mating section 331 extends along the inner wall of the slot 21a and is limited within the slot 21a. One end of the first mating section 331 exposed in the slot 21a is bent outward to form the second mating section 332, and the second mating section 332 extends into the limiting hole 21b.

[0032] In this embodiment, combined with Figure 6 To further enhance the structural stability of the previous embodiment, a double limiting mechanism of the limiting hole 21b and the retaining groove 21a is provided, making the retaining spring 3 more securely fixed within the lower shell 2, effectively preventing displacement or loosening of the retaining spring 3 during use, and improving the reliability of the connection between the upper shell 1 and the lower shell 2. The first mating section 331 is confined within the retaining groove 21a, providing radial limiting; while the second mating section 332 extends into the limiting hole 21b, providing axial limiting. This double limiting ensures that the retaining spring 3 will not shift in multiple directions. It should be noted that the cross-sectional shape of the limiting hole 21b can be circular, with the second mating section 332 extending into the circular limiting hole 21b. Utilizing the symmetry and guiding nature of the circular hole, it facilitates the quick installation and removal of the retaining spring 3. The cross-sectional shape of the limiting hole 21b can also be square, ensuring that the second mating section 332 will not rotate or shift after extending into the square limiting hole 21b. The shape of the limiting hole 21b here includes, but is not limited to, these two forms, with a circular cross-sectional shape being preferred.

[0033] In one embodiment of the present invention, the electronic device further includes a mating component 4, which is connected to the lower shell 2 and covers the lower shell 2; the mating component 4 abuts against the side surface of the retaining spring 3 facing away from the lower shell 2.

[0034] In this embodiment, to provide additional protection, combined with Figure 1 and Figure 4 It should be noted that the mating part 4 is similar in form to the middle shell, and it covers the inner wall of the lower shell 2. The connection methods between the mating part 4 and the lower shell 2 include, but are not limited to, plug-in and bolt connections. Because the mating part 4 abuts against the surface of the retaining spring 3, the retaining spring 3 will not loosen or shift during use. Figure 4 The mating part 4 includes a covering section and a plug-in section. The covering section covers the inner wall of the lower shell 2 and forms a space with the bottom wall of the lower shell 2 to accommodate other components and the retaining spring 3. The bottom wall of the lower shell 2 has a plug-in hole, and the plug-in section is inserted into the plug-in hole. The lower shell 2 and the mating part 4 are further locked together by bolts or other fasteners. Figure 8 It is understood that the mating part 4 abuts against the surface of the body 31 to generate a clamping force on the retaining spring 3, preventing the retaining spring 3 from moving upward, thereby achieving axial fixation between the upper shell 1 and the lower shell 2. In one embodiment, the mating part 4 is formed by a protrusion on the inner wall of the lower shell 2, which abuts against the surface of the retaining spring 3 body 31; in another embodiment, the mating part 4 is formed by a threaded hole on the inner wall of the lower shell 2, and a threaded pressure plate is used to fix it to the lower shell 2 by a threaded connection, with one side of the threaded pressure plate abutting against the surface of the retaining spring 3 body 31. In yet another embodiment, the mating part 4 may also be in the form of a hook on the inner wall of the lower shell 2, which abuts against the surface of the retaining spring 3 body 31; or in the form of a magnetic pressure block on the inner wall of the lower shell 2, which is magnetically attracted to the surface of the retaining spring 3 body 31, etc. Here, the mating part 4 is preferably in the form of a middle shell, covering the lower shell 2. The above-mentioned arrangement not only enhances the connection stability between the retaining ring 3 and the lower shell 2, but also prevents the retaining ring 3 from being impacted or worn by the outside world.

[0035] In one embodiment of the present invention, the limiting groove 11 has two guide walls 111 arranged opposite to each other and a bottom wall 112 located between the two guide walls 111. The two guide walls 111 are located on both sides of the length extension direction of the bottom wall 112. The distance between the two guide walls 111 gradually increases from the end closer to the bottom wall 112 to the end farther away from the bottom wall 112.

[0036] In this embodiment, combined with Figure 3 To facilitate the connection between the limiting groove 11 and the snap-fit ​​part 32, the distance between the two guide walls 111 gradually increases from the end closer to the bottom wall 112 to the end farther from the bottom wall 112, thereby increasing the contact area between the snap-fit ​​part 32 and the limiting groove 11, thus improving the stability of the snap ring 3 within the limiting groove 11 and reducing the possibility of loosening. It is understandable that, combined with... Figure 7 and Figure 9The distance between the two guide walls 111 gradually increases from the end closer to the bottom wall 112 to the end farther from the bottom wall 112, forming a funnel-shaped or flared structure. This design provides good guidance for the retaining spring 3 to engage in the limiting groove 11, allowing it to enter the limiting groove 11 more easily and accurately, avoiding installation difficulties or damage caused by inaccurate alignment. It is understood that the guide wall 111 can be beveled or curved, depending on the specific circumstances.

[0037] In one embodiment of this utility model, a through hole 22 is provided at one end of the lower shell 2 near the limiting groove 11, and the buckle part 32 passes through the through hole 22 and abuts against the limiting groove 11.

[0038] In this embodiment, combined with Figure 4 and Figure 7 To facilitate installation and disassembly, the snap-fit ​​portion 32 of the snap ring 3 can easily pass through the lower housing 2 and extend into the limiting groove 11, reducing installation difficulty and improving assembly efficiency. It is understood that the shape of the through hole 22 is adapted to the shape of the snap-fit ​​portion 32. This design enhances connection stability.

[0039] In one embodiment of the present invention, a limiting groove 11 is provided on each of the opposite side walls of the upper shell 1, and a through hole 22 is provided on each of the opposite side walls of the lower shell 2, with each through hole 22 corresponding to each limiting groove 11; the electronic device includes two retaining springs 3, each retaining spring 3 including a latching part 32, each latching part 32 passing through a through hole 22 and abutting against a limiting groove 11.

[0040] In this embodiment, the symmetrical distribution of the two retaining rings 3 ensures a uniform stress distribution between the upper shell 1 and the lower shell 2, making the connection between the upper shell 1 and the lower shell 2 more stable, able to withstand greater external impacts, and extending the service life of the equipment. Combined with... Figure 4 and Figure 7 It should be noted that the two retaining springs 3 are respectively disposed on opposite sides of the lower shell 2 to achieve the connection between the lower shell 2 and the upper shell 1. Furthermore, in order to enhance the connection between the upper shell 1 and the lower shell 2, each retaining spring 3 includes a latching part 32, which has two protrusions, and the two protrusions respectively pass through the bottom shell and abut against the limiting groove 11.

[0041] In one embodiment of the present invention, the buckle part 32 includes a first protrusion 321, a third connecting section 322 and a second protrusion 323. The two ends of the third connecting section 322 are respectively connected to the first protrusion 321 and the second protrusion 323. The body 31 is respectively connected to the first protrusion 321 and the second protrusion 323. The first protrusion 321 and the second protrusion 323 are respectively inserted into the lower shell 2 and abut against the limiting groove 11.

[0042] In this embodiment, combined with Figure 5It should be noted that the first protrusion 321 and the second protrusion 323 respectively pass through the lower shell 2 and abut against the limiting groove 11, forming multi-point contact, which significantly enhances the connection stability between the retaining ring 3 and the lower shell 2 and the upper shell 1. The first protrusion 321 and the second protrusion 323 respectively cooperate with the through hole 22 and the limiting groove 11 to provide radial limiting and prevent the retaining ring 3 from moving in the radial direction. It can be understood that one end of the body 31 can be connected to the first protrusion 321 and the second protrusion 323 at the same time, which improves the structural stability of the retaining ring 3 during operation and reduces the possibility of deformation of the retaining ring 3 under force. The body 31 can also be divided into two sections, with the two sections respectively connected to the first protrusion 321 and the second protrusion 323. For details, please refer to the next embodiment, which will not be elaborated here.

[0043] In one embodiment of this utility model, the body 31 has a first connecting segment 311 and a second connecting segment 312 arranged in parallel. The first connecting segment 311 is connected to a first protruding segment 321, and the second connecting segment 312 is connected to a second protruding segment 323.

[0044] The main body 31 also includes a mating part 33, which includes two first mating sections 331 and two second mating sections 332 arranged in parallel. One of the first mating sections 331 is connected to the first connecting section 311, and the other first mating section 331 is connected to the second connecting section 312.

[0045] In this embodiment, combined with Figure 5 To improve connection flexibility, the first connecting segment 311 is connected to the first protruding segment 321, and the second connecting segment 312 is connected to the second protruding segment 323, giving the snap ring 3 better flexibility within a certain range. Under stress, the first connecting segment 311 and the second connecting segment 312 can transmit and distribute the force separately, avoiding uneven force distribution that occurs when the same body 31 is connected to the first protruding segment 321 and the second protruding segment 323 respectively, thus improving the overall load-bearing capacity and reliability of the snap ring 3.

[0046] In one embodiment of the present invention, the first protrusion 321 is gradually widened from the end near the body 31 to the end away from the body 31, and the first protrusion 321 is gradually widened from the end near the third connecting segment 322 to the end away from the third connecting segment 322.

[0047] The second protruding section 323 is gradually widened from the end near the body 31 to the end away from the body 31. The second protruding section 323 is gradually widened from the end near the third connecting section 322 to the end away from the third connecting section 322.

[0048] In this embodiment, to facilitate the installation of the snap-fit ​​part 32 and the limiting groove 11, the gradually expanding portion of the first protrusion 321 acts as a guide, making it easier for the protrusion of the snap ring 3 to align with and enter the through hole 22 and the limiting groove 11, reducing installation difficulty and improving assembly efficiency. Simultaneously, it achieves better fit with the two guide walls 111 of the limiting groove 11, increasing the contact area and improving the connection stability of the snap ring 3.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
