Abstract
Description
Technical Field
[0001] This application relates to products with anti-leakage function, and more particularly to anti-leakage components and electronic products. Background Technology
[0002] Electronic products need to prevent the omission of components. Taking a smoke detector as an example, the aforementioned omission prevention is explained as follows: For a smoke detector, the component to prevent omission is the battery. Omission prevention means preventing consumers from forgetting to install the battery in the smoke detector. The function of omission prevention is: if the consumer forgets to install the battery, the smoke detector cannot be assembled or installed, thus reminding the consumer to install the battery.
[0003] Technicians have discovered that existing electronic products are too bulky, which is not conducive to making electronic products small and thin. Utility Model Content
[0004] The purpose of this application is to disclose an anti-leakage assembly and an electronic product. The anti-leakage assembly does not occupy the space of other components, and its small size also makes the electronic product small and lightweight.
[0005] In a first aspect, this application discloses a leak-proof assembly. The leak-proof assembly includes an upper shell, a lower shell, a blocking member, and an elastic member. The lower shell includes a receiving compartment for accommodating a leak-proof object. The elastic member and the blocking member are assembled and both are located within the receiving compartment. In a first state, the elastic member is located within the lower shell, and the upper shell and the lower shell are assembleable. In a second state, the elastic member extends out of the lower shell, and the upper shell and the lower shell are not assembleable.
[0006] In some embodiments, the elastic element is a torsion spring, including a first torsion arm, an energy storage portion, and a second torsion arm; the first torsion arm includes a head end connected to the blocking member and a tail end connected to the energy storage portion; the energy storage portion is assembled with the blocking member; a groove is provided in the receiving chamber; the second torsion arm is connected to the energy storage portion and includes a sliding head end relative to the energy storage portion; during the transition between the first state and the second state, the sliding head end slides within the groove.
[0007] In some embodiments, the blocking member includes a blocking member body and wings; the same side of the blocking member body is connected to the head end of the first torsion arm and the energy storage part; the wings are symmetrically arranged relative to the blocking member body and are also rotatably connected to the wall of the receiving chamber.
[0008] In some embodiments, the wing includes a wing root connected to the blocking body, and the energy storage portion is located between the wing root and the tip.
[0009] In some embodiments, the wings and the bin wall are rotatably connected by a pivot structure, which is located between the energy storage section and the slide head end along the length of the slide groove.
[0010] In some embodiments, the anti-leakage assembly includes a mounting plate and a circuit board; the circuit board is at least partially attached to the lower housing and is provided with an anti-tamper spring clip; the lower housing is provided with an anti-tamper arm. When the mounting plate is mounted to the lower housing, the mounting plate abuts against the anti-tamper arm, and the anti-tamper arm disengages the anti-tamper spring clip from the corresponding contact of the circuit board. When the mounting plate is detached from the lower housing, the mounting plate disengages from the anti-tamper arm, and the anti-tamper spring clip returns to its original position and abuts against the contact.
[0011] In some embodiments, the leak-proof assembly includes a mounting plate, one of which, along with the lower housing, is provided with a tactile spring arm, and the other is provided with a travel groove and a clearance position communicating with the travel groove. During rotation of the mounting plate relative to the lower housing, the tactile spring arm moves within the travel groove and presses against the groove wall to generate damping; when the mounting plate is rotated into position, the tactile spring arm is located within the clearance position, and the damping between it and the mounting plate disappears.
[0012] In some embodiments, the leak-proof assembly includes a circuit board located between the lower housing and the upper housing; the upper housing includes an outer upper housing and an inner upper housing, the outer upper housing including an outer upper housing contact arm; the inner upper housing including an inner upper housing spring arm. When the outer upper housing is pressed, the outer upper housing contact arm and the inner upper housing spring arm contact each other, triggering a button on the circuit board.
[0013] In some embodiments, the upper housing includes an upper housing body, and the upper housing contact arm is arc-shaped and spaced apart from the upper housing body; both ends of the upper housing contact arm are connected to the upper housing body.
[0014] In some embodiments, the upper inner shell includes an upper inner shell body, the upper inner shell spring arm is arc-shaped and spaced apart from the upper inner shell body; the two ends of the upper inner shell contact arm are connected to the upper outer shell body.
[0015] In some embodiments, the upper shell includes an outer upper shell, a mesh cover, and an inner upper shell, the mesh cover being located between the edge of the outer upper shell and the edge of the inner upper shell, the mesh cover being wrapped around the upper shell.
[0016] Secondly, this application discloses an electronic product. The electronic product includes any of the aforementioned leak-proof components, wherein the leak-proof component is a battery.
[0017] Regarding the aforementioned leak-proof assembly and electronic product, since both the blocking member and the elastic member of the leak-proof assembly are located within the receiving compartment, when the elastic member is in the first state, the blocking member is located within the lower shell, and the upper shell and the lower shell can be assembled; when the elastic member is in the second state, the blocking member extends out of the lower shell, and the upper shell and the lower shell cannot be assembled. On the one hand, this application utilizes the space of the receiving compartment itself, which, compared to the blocking member and the elastic member being located outside the receiving compartment, does not occupy the space outside the receiving compartment, allowing for better control of the size of the leak-proof assembly. Consequently, the size of the leak-proof assembly or electronic product can be made smaller (for example, at least utilizing the space in the thickness direction of the receiving compartment of the electronic product). On the other hand, the receiving compartment usually leaves a margin for accommodating the leak-proof object, and when the leak-proof object is assembled, the blocking member and the elastic member are both located within the receiving compartment, which can utilize this margin. Therefore, the design of this application will not increase the volume of the receiving compartment. Ultimately, based on the above two reasons, the leak-proof assembly is small in size, which is beneficial for achieving small and thin electronic products. In addition, the anti-leakage assembly includes a blocking component, an elastic component, an upper shell, and a lower shell (the upper shell and lower shell can be the upper and lower shells of the electronic product itself). The anti-leakage assembly has a simple structure and can also make the electronic product small and thin. Attached Figure Description

[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0034] This application discloses an anti-leakage component and an electronic product, the latter including any of the anti-leakage components of this application. The electronic product shown in this application is a smoke detector, and the object to be prevented from leaking is a battery. Smoke detectors are used in the field of fire detection, capable of timely detecting smoke concentration and issuing an alarm to prevent fires. However, those skilled in the art will understand that the electronic product is not limited to a smoke detector; it is an electronic product with an anti-leakage requirement.
[0035] Before introducing the structure of this application, some terms are explained as follows: For terms containing the same words in this application, their structures may be the same or different. Prefixes are added to them only for distinguishing nouns. For example, "tactile spring arm," "anti-tamper spring arm," and "upper inner shell spring arm" described later are all spring arms and can adopt the same or different structures. The prefixes "tactile," "anti-tamper," and "upper inner shell" are only used to distinguish them.
[0036] See Figures 1 to 4 The anti-leakage assembly includes an upper shell 1, a lower shell 3, a blocking member 21, and an elastic member 22. In this application, the upper shell 1 is the upper shell of the electronic product itself, and the lower shell 3 is the lower shell of the electronic product itself. In other embodiments, each component of the anti-leakage assembly is an independent component relative to the electronic product as a whole. The anti-leakage assembly is assembled with related components of the electronic product as a module. For example, the outer shell of the electronic product includes the upper shell 1 and another part of the outer shell, and the upper shell 1 is assembled with the other part of the outer shell.
[0037] See Figures 1 to 4 The lower shell 3 includes a receiving compartment 31 for accommodating a leak-proof object. In this application, the leak-proof object 9 is a battery (i.e., to prevent battery leakage), and the receiving compartment 31 is also referred to as a battery compartment. Based on the above configuration, the leak-proof object 9 is located within the space enclosed by the upper shell 1 and the lower shell 3, representing a built-in leak-proof object solution. The elastic member 22 and the blocking member 21 are assembled and both are located within the receiving compartment 31. When the elastic member 22 is in its first state, the blocking member 21 is located within the lower shell 3, and the upper shell 1 and the lower shell 3 are assembleable. "Assembleable" means that the upper shell 1 and the lower shell 3 can be assembled into the casing of an electronic product. See also... Figure 5 and Figure 9In this application, the upper shell 1 includes a fixing post 131, and the lower shell 3 includes a mounting post 37. The mounting post 37 and the fixing post 131 are connected by screws, thereby assembling the upper shell 1 and the lower shell 3 together. When the elastic member 22 is in the second state, the blocking member 21 extends out of the lower shell 3. The extent to which the blocking member 21 extends out of the lower shell 3, or from which point in the lower shell 3, is not limited. The function of the blocking member 21 extending out of the lower shell 3 is to prevent the assembly between the lower shell 3 and the upper shell 1, making the upper shell 1 and the lower shell 3 non-assembleable. The method of non-assembly is not limited. For example, after the blocking member 21 extends out of the lower shell 3, the upper shell 1 can be lifted by the blocking member 21 and cannot be closed with the lower shell 3, thus preventing assembly. Alternatively, the upper shell 1 and the lower shell 3 can be assembled by rotation, and the blocking effect of the blocking member 21 prevents the upper shell 1 and the lower shell 3 from rotating and locking. Through this non-assembly, the consumer knows that the electronic product is not equipped with a leak-proof object 9 (battery). In the embodiments of this application, the first state is that the elastic element 22 is in a working state, and the second state is that the elastic element 22 is in a natural state. However, the first and second states are not limited to these, as long as the elastic element 22 has two different states. Based on the function played by the cooperation of the blocking element 21 and the elastic element 22, the blocking element 21 and the elastic element 22 are not limited to the following... Figure 2 and Figure 4 The structure is shown. In this application, the first state is that the elastic element 22 is in the working state, and the second state is that the elastic element 22 is in the natural state. However, those skilled in the art will understand that in other possible cases, the first state may be that the elastic element 22 is in the natural state, and the second state may be that the elastic element 22 is in the working state.
[0038] In some related designs, the elastic element 22 and the blocking element 21 are located outside the receiving compartment 31. In this way, the elastic element 22 and the blocking element 21 will occupy the space outside the receiving compartment of the electronic product, which is not conducive to controlling the size of the product and results in a larger electronic product.
[0039] As described above, since both the blocking member 21 and the elastic member 22 of the anti-leakage assembly are located within the receiving chamber 31, when the elastic member 22 is in the first state, the blocking member 21 is located within the lower shell, and the upper shell 1 and the lower shell 3 can be assembled; when the elastic member 22 is in the second state, the blocking member 21 extends out of the lower shell 3, and the upper shell 1 and the lower shell 3 cannot be assembled. On the one hand, this application utilizes the space of the receiving chamber 31 itself, and compared to the blocking member 21 and the elastic member 22 being located outside the receiving chamber 31, it does not occupy the space outside the receiving chamber 31, thus allowing for better control of the anti-leakage assembly. The size of the anti-leakage assembly, and consequently the electronic product, makes it small (for example, it utilizes at least the thickness of the storage compartment 31 of the electronic product, and in some cases, also the lateral space of the storage compartment). Furthermore, the storage compartment 31 typically has a margin for accommodating the anti-leakage object 9. When the anti-leakage object is assembled, the blocking member 21 and the elastic member 22 are both located within the storage compartment 31, utilizing this margin. Therefore, the design of this application does not increase the volume of the storage compartment 31. Ultimately, based on the above two reasons, the anti-leakage assembly is small, which is beneficial for miniaturizing and thinning electronic products. In addition, the anti-leakage assembly includes a blocking member 21, an elastic member 22, an upper shell 1, and a lower shell 3 (the upper shell 1 and lower shell 3 can utilize the upper and lower shells of the electronic product itself). The structure of the anti-leakage assembly is simple, which also makes the electronic product small and thin.
[0040] See Figures 1 to 4 The elastic element 22 is a torsion spring, including a first torsion arm 221, an energy storage portion 222, and a second torsion arm 223. The first torsion arm 221 includes a head end 2211 connected to the blocking member 21 and a tail end connected to the energy storage portion 222. The connection method between the head end and the blocking member 21 is not limited; for example, the side of the blocking member 21 includes a hook groove 212, and the head end 2211 is a barb that hooks into the hook groove 212 to achieve the connection.
[0041] In this embodiment, the energy storage unit 222 is circular, but it is not limited to this shape; it is sufficient to achieve the energy storage function. The energy storage unit 222 is assembled with the blocking member 21; the assembly method is not limited, see [link to documentation]. Figure 4 The blocking member 21 includes a mounting shaft 213, which includes a buckle 214. The energy storage unit 222 is assembled with the mounting shaft 213 and is restrained by the buckle 214, preventing it from detaching from the mounting shaft 213.
[0042] The second torsion arm 223 is connected to the energy storage unit 222 and includes a sliding end 2231 relative to the energy storage unit 222; see also Figure 2 The receiving chamber 31 is provided with a sliding groove 311. During the transition between the first state and the second state, the sliding end 2231 of the torsion spring slides within the sliding groove 311.
[0043] Combination Figures 1 to 4 With the elastic element 22 being a torsion spring, the method for achieving leak prevention is described below:
[0044] See Figure 3 and combined Figure 4 When the leak-proof object 9 is assembled, the elastic member 22 is in the first state (working state) under the force of the leak-proof object 9. The energy storage part 222 and the slider end 2231 store energy. The slider end 2231 is close to the electrode spring 91. At the same time, the blocking member 21 is retracted into the lower shell 3 due to the force of the elastic member 22. In this way, no part blocks the upper shell 1, so the upper shell 1 and the lower shell 3 can be assembled.
[0045] See Figure 1 and Figure 2 Without assembling or removing the leak-proof object 9: the elastic member 22 is not subjected to the force of the leak-proof object 9, the sliding end 2231 is located in the groove 311, but away from the electrode spring 91 for contacting the leak-proof object 9, the elastic member 22 releases the torque and is in the second state (natural state), at the same time, the torque will spring the blocking member 21 back to the initial state, so that the blocking member 21 extends out of the lower shell 3, and thus, the upper shell 1 and the lower shell 3 cannot be assembled.
[0046] As described above, since the elastic element 22 is a torsion spring, the first torsion arm 221 and the energy storage part 222 are both connected to the blocking element 21, and the sliding end 2231 of the second torsion arm 223 can slide in the groove 311 of the receiving compartment 31. In this way, when the leak-proof object 9 is assembled in the receiving compartment 31, the blocking element 21 and the torsion spring are in a state similar to lying in the receiving compartment 31 (when the leak-proof object 9 is a battery, the blocking element 21 and the torsion spring can be considered to be located in the receiving compartment 31 along the length direction of the battery). Therefore, it is at least beneficial to reduce the size of the receiving compartment 31 in the height direction, which is beneficial to the small size of the leak-proof assembly and electronic products.
[0047] See Figure 4 The blocking member 21 includes a blocking member body 215 and wings 216 disposed on the blocking member body 215 and wings 216. The blocking member body 215 is connected on the same side to the head end 2211 of the first torsion arm 221 and the energy storage section 222. The wings 216 are symmetrically arranged relative to the blocking member body 215 and are also rotatably connected to the wall of the receiving compartment 31. After symmetrical arrangement, the outline formed by the wings 216 and the blocking member body 215 is approximately the same as the outline of the leak-proof object 9. For example, if the leak-proof object 9 is a battery, then the outline formed by the wings 216 and the blocking member body 215 is arc-shaped. The rotatable connection between the wings 216 and the compartment wall is not limited; for example, Figure 4 The diagram illustrates that a pivot 211 is provided at the end of wing 216. Figure 2 The diagram shows that the bin wall is provided with a pivot hole 312. The pivot 211 is inserted into the pivot hole 312 in a one-to-one correspondence to achieve a rotatable connection.
[0048] As described above, since the same side of the blocking body 215 is connected to the head end 2211 and the energy storage part 222 of the first torsion arm 221, and the wings 216 are symmetrically arranged relative to the blocking body 215, the blocking member 21 is subjected to uniform force and moves smoothly during the transition between the elastic member 22 and the first state. The sliding end 2231 is also easier to slide in the groove 311, thus making it more convenient and easier to install and remove the leak-proof object 9.
[0049] See Figure 4 The wing 216 includes a wing root 2161 connected to the blocking body 215, and the energy storage part 222 is located between the wing root 2161 and the head end 2211.
[0050] As described above, the energy storage unit 222 is located between the wing root 2161 and the tip 2211, which makes it easier for the energy storage unit 222 to release energy, so that the torsion spring can switch more easily between the first state and the second state, and the installation and removal of the leak-proof object 9 is more convenient and easier.
[0051] See Figure 4 The wing 216 and the bin wall are rotatably connected by a pivot structure, which is not limited to the structure formed by the pivot 211 and the pivot hole 312 shown in the figure. Along the length of the slide groove 311, the pivot structure is located between the energy storage part 222 and the slide head end 2231.
[0052] As described above, since the rotating shaft structure is located between the energy storage section 222 and the sliding end 2231, it is easier for the energy storage section 222 to release energy, so that the torsion spring can switch more easily between the first state and the second state, and the installation and removal of the leak-proof object 9 is more convenient and easier.
[0053] See Figure 13 , Figure 14 , Figure 5 and Figure 1 The anti-leakage assembly includes a mounting plate 6 and a circuit board 7. The circuit board 7 can be one of two types: a) the circuit board 7 is part of the entire electronic product; 2) the circuit board 7 is related to the anti-leakage function, meaning the circuit board of the entire electronic product includes the circuit board 7 and other circuit boards. One implementation of this type is as follows: the anti-leakage assembly can be assembled as a module with related structures of the electronic product, enabling electronic products that do not have an anti-leakage function to possess it. The circuit board 7 is fixed to the lower shell 3 by a snap-fit structure, although... Figure 5 and Figure 13 The circuit board clip 32 with a snap-fit structure is shown, but the structure of the mating clip that cooperates with the circuit board clip 32 can be deduced from the structure of the circuit board clip 32. Figure 7 , Figure 11 and Figure 13 The illustration shows that the circuit board 7 is partially attached to the lower housing 3. However, in some variations, the circuit board 7 may be fully attached to the lower housing 3. The circuit board 7 is provided with an anti-tamper spring clip 71. Figure 13 In the circuit board 7, the anti-tamper spring clip 71 and the bottom shell 3 are located on opposite sides of the bottom shell 3. The bottom shell 3 is provided with an anti-tamper spring arm 33.
[0054] See Figure 13 and Figure 14 When the mounting plate 6 is installed with the lower housing 3, the mounting plate 6 abuts against the anti-tamper arm 33, and the anti-tamper arm 33 causes the anti-tamper spring clip 71 to disengage from the corresponding contact of the circuit board 7. The structure of the anti-tamper arm 33 is not limited; in this embodiment, the anti-tamper arm 33 includes opposing spring clip abutment portions 331 and mounting plate abutment portions. The spring clip abutment portion 331 may, for example, be cross-shaped. When the mounting plate 6 is installed with the lower housing 3, the mounting plate 6 abuts against the mounting plate abutment portion, causing the spring clip abutment portion 331 to move away from the circuit board 7 (e.g., in…). Figure 13 and Figure 14 (The spring is lifted upwards), and then the spring contact part 331 pushes the anti-tamper spring 71, causing the anti-tamper spring 71 to disengage from the corresponding contact of the circuit board 7. When the mounting plate 6 is disassembled from the lower shell 3, the mounting plate 6 disengages from the anti-tamper spring arm 33, the anti-tamper spring 71 is no longer under force, and the anti-tamper spring 71 returns to its original position and contacts the contact.
[0055] The mounting plate 6 is typically installed on a wall or similar surface. The upper shell 1, lower shell 3, blocking member 21, and elastic member 22 can be considered the main body of the anti-leakage assembly. For electronic products, these components can be considered the main body of the electronic product (e.g., the detector body). When the main body of the electronic product is removed, the anti-tamper spring 71 contacts the corresponding contacts on the circuit board 7, activating the relevant components of the electronic product (e.g., activating the buzzer 8, which sounds and is fixed in the mounting compartment 133), thus reminding the consumer that the main body of the electronic product has been removed. Therefore, the change in the contact and detachment state of the anti-tamper spring 71 with the corresponding contacts on the circuit board 7 serves as a reminder of the electronic product's removal status. In some cases, the illumination or de-illumination of the light guide column 4 can also serve as a reminder. Furthermore, as... Figure 1 and Figure 6 As shown, the electronic product also includes a DIP switch 5, which can be used to turn the electronic product on or off.
[0056] As described above, since the circuit board 7 is at least partially attached to the lower shell 3, the lower shell 3 is provided with an anti-tamper arm 33, and the circuit board 7 is provided with an anti-tamper spring piece 71, the thickness of the assembly formed by the lower shell 3 and the circuit board 7 can be considered as the sum of the thickness of the lower shell 3 and the thickness of the circuit board 7. This is beneficial to the fact that the anti-leakage component or the electronic product is thinner and lighter, and consequently, the electronic product is smaller and lighter.
[0057] See Figure 6 , Figure 7 and Figure 8 The lower shell 3 is provided with a tactile spring arm 35. The mounting plate 6 is provided with a travel groove 61 and a clearance position 63 communicating with the travel groove 61. Since the movement is relative, the lower shell 3 can also be provided with the travel groove 61 and the clearance position 63, and the mounting plate 6 can be provided with the tactile spring arm 35. During the rotation of the mounting plate 6 relative to the lower shell 3 (for example, Figure 6 In the middle, the mounting plate 6 rotates counterclockwise relative to the lower shell 3 (see...). Figure 7 and Figure 8 The tactile spring arm 35 moves within the travel groove 61 and presses against the groove wall, providing a rebound force to generate damping; see also Figure 6 When the mounting plate 6 is rotated into position, the tactile spring arm 35, after disengaging from the groove wall, is located within the clearance position 63 and pops out from the clearance position 63. Thus, the damping between the tactile spring arm 35 and the mounting plate 6 disappears. "Disappearance of damping" includes the following situations: 1) damping is zero; 2) it is not zero but there is a significant difference in damping compared to the damping of the tactile spring arm 35 against the groove wall, so that the consumer can feel the change in damping when rotating the mounting plate 6. In some cases, this can be accompanied by a clicking sound. The aforementioned rotation of the mounting plate 6 into position can be achieved in various ways. For example, the mounting plate 6 is provided with a positioning rib 62, and the lower shell 3 is provided with a lower shell latch 36. When the lower shell latch 36 abuts against the positioning rib 62, the mounting plate 6 rotates into position.
[0058] As described above, during the rotation of the mounting plate 6, the damping between the tactile spring arm 35 and the mounting plate 6 changes from damped to zero, providing a tactile feedback to indicate that the installation is in place, resulting in a good user experience.
[0059] See Figure 9 , Figure 10 , Figure 11 and Figure 12The leak-proof assembly includes a circuit board 7 located between the lower shell 3 and the upper shell 1. The circuit board 7 and the lower shell 3 can be at least partially attached, as previously described, to facilitate the height dimensions of small electronic products. In some scenarios where height requirements are not high or not required, the circuit board 7 and the lower shell 3 may not be attached. The upper shell 1 includes an outer shell 11 and an inner shell 13. The assembly method of the outer shell 11 and the inner shell 13 is not limited; for example, the outer shell 11 includes an outer shell clip 111. Figure 9 The diagram illustrates that the upper outer shell 11 and the upper inner shell 13 are fastened together by the upper outer shell snap 111 and the corresponding structure of the upper inner shell 13. Furthermore, the upper outer shell 11 includes a foolproof positioning rib 112. The foolproof positioning rib 112 ensures correct assembly between the upper outer shell 11 and the upper inner shell 13. The upper outer shell 11 includes an upper outer shell contact arm 113. The upper inner shell 13 includes an upper inner shell spring arm 132. When the upper outer shell 11 is pressed, the upper outer shell contact arm 113 and the upper inner shell spring arm 132 contact each other, pressing the upper inner shell spring arm 132 downwards. The stroke of this movement triggers a button on the circuit board 7, thus giving the upper shell 1 a button function. The button function can be set by the manufacturer.
[0060] As described above, since the upper outer shell contact arm 113 and the upper inner shell spring arm 132 are in contact, and the button function is realized by triggering the button on the circuit board 7 through the upper inner shell spring arm 132, the upper outer shell contact arm 113 and the upper inner shell spring arm 132 are formed by the upper outer shell 11 and the upper inner shell 13. There is no need to set up an additional button structure, which helps to save structural components and the electronic product has fewer parts.
[0061] See Figure 9 and Figure 10 The upper outer shell 11 includes an upper outer shell body 110, and an upper outer shell contact arm 113 is arc-shaped and spaced apart from the upper outer shell body 110. Both ends of the upper outer shell contact arm 113 are connected to the upper outer shell body 110, for example, the two ends are respectively connected to the upper outer shell body 110 through a connecting part 114.
[0062] See Figure 9 The upper inner shell 13 includes an upper inner shell body 130. The upper inner shell spring arm 132 is arc-shaped and spaced apart from the upper inner shell body 130; both ends of the upper inner shell contact arm 132 are connected to the upper outer shell body 110.
[0063] As described above, the upper outer shell contact arm 113 is arc-shaped and spaced apart from the upper outer shell body 110, and the upper inner shell spring arm 132 is arc-shaped and spaced apart from the upper inner shell body 130. Satisfying either one of these conditions will result in a smaller spring force, making it easier to press the upper shell 1 to trigger the button on the circuit board 7.
[0064] See Figure 1 and Figure 3 The upper shell 1 includes an outer shell 11, a mesh cover 12, and an inner shell 13. The material of the mesh cover 12 is not limited, for example, metal (in this case, the mesh cover 12 is a metal mesh). The mesh cover 12 surrounds the upper shell 1 and is located between the edge of the outer shell 11 and the edge of the inner shell 13.
[0065] As described above, since the mesh cover 12 surrounds the upper outer shell 11 and is located between the edge of the upper outer shell 11 and the edge of the upper inner shell 13, the upper shell 1 has a full circle of mesh cover 12, which enhances the quality of preventing leaks in components or electronic products.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
