Detailed Implementation

[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] refer to Figures 1 to 6 This application provides an electronic device 100. The electronic device 100 can be, for example, a mobile phone, a tablet computer, a laptop computer, etc. This application is not limited to this. The electronic device 100 includes a housing portion 1, a switch portion 2, and an electronic control portion 3. The housing portion 1 surrounds a receiving cavity 11 and includes an opening unit 12 communicating with the receiving cavity 11. The switch portion 2 is disposed in the receiving cavity 11 and protrudes from the opening unit 12. The switch portion 2 is movable along the extending direction of the opening unit 12. The electronic control portion 3 is disposed in the receiving cavity 11 and includes a circuit board 31 and a multi-pole Hall switch 32. The multi-pole Hall switch 32 includes a plurality of Hall elements 321 and a plurality of magnetic elements 322. The plurality of Hall elements 321 and the plurality of magnetic elements 322 are distributed along the moving direction of the switch portion 2. The circuit board 31 is disposed opposite to the switch portion 2. The magnetic elements 322 are disposed on the side of the switch portion 2 facing the circuit board 31. The Hall elements 321 are disposed on the side of the circuit board 31 facing the switch portion 2 and are electrically connected to the circuit board 31.

[0035] With this configuration, when the switch unit 2 moves within the opening unit 12, it drives the magnetic component 322 to move, thereby cooperating with the Hall unit 321 to trigger the Hall effect. Upon receiving the voltage change generated by the Hall effect, the circuit board 31 switches the function of the electronic device 100. Thus, the electronic device 100 can switch functions via mechanical toggle. Furthermore, the multi-polar Hall switch 32 prevents false triggering of the Hall effect caused by the proximity of a single-polarity magnet, such as a magnetic capacitive pen or keyboard. Therefore, the electronic control unit 3 has a foolproof function.

[0036] It should be noted that the extending direction of the opening unit 12 should be understood as a direction other than the direction in which the opening unit 12 and the receiving cavity 11 communicate. For example... Figure 1 As shown, the communication direction between the opening unit 12 and the accommodating cavity 11 is along the second direction Y; the extending direction of the opening unit 12 is along the first direction X. Therefore, the switching part 2 can move along the first direction X. The plurality of magnetic elements 322 and the plurality of Hall elements 321 are also similarly distributed along the first direction X (e.g., ...). Figure 4(As shown). Furthermore, the opening unit 12 can be located on the top, bottom, or side of the electronic device 100. This application does not limit this.

[0037] Of course, in other embodiments, the extension direction of the opening unit 12 can be along the third direction Z. Then the switching part 2 can move along the third direction Z. In this case, the Hall unit 321 and the magnetic element 322 are also distributed along the third direction Z. In the embodiment shown in the figures, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular. However, this should be considered exemplary and not limiting. The first direction X, the second direction Y, and the third direction Z only need to be mutually non-parallel.

[0038] In an optional embodiment, the number of Hall elements 321 includes four, and the number of magnetic elements 322 includes two. The two magnetic elements 322 have opposite magnetic properties. This embodiment is an example of a four-Hall switch. Thus, each Hall element 321 needs to alternately sense either the N-pole magnetic field or the S-pole magnetic field. When the magnetic element 322 is moved by the switching unit 2, the magnetic field polarity alternately covers the four Hall elements 321, thereby triggering the Hall effect. In this embodiment, the number of Hall elements 321 and the number of magnetic elements 322 can be effectively controlled, and false triggering by a single magnet can be avoided, which helps to reduce the volume occupied by the electronic control unit 3.

[0039] In some embodiments, the circuit board 31 is a rigid circuit board. The circuit board 31 can then be placed within the accommodating cavity 11 parallel to the first direction X and the third direction Z, and fixedly connected to the housing portion 1. In this case, the surface of the circuit board 31 facing the switching portion 2 is used to house the Hall unit 321, allowing the Hall unit 321 to be positioned opposite to the magnetic element 322 on the switching portion 2. In other embodiments, as shown in the accompanying drawings, the circuit board 31 is a flexible printed circuit (FPC). In this case, the circuit board 31 can be flexibly positioned according to the wiring requirements inside the accommodating cavity 11. It should be noted that this application does not limit the specific shape of the flexible circuit board. Therefore, the flexible circuit board shown in the accompanying drawings should be considered exemplary rather than restrictive.

[0040] refer to Figure 2 , Figure 3 and Figure 4Optionally, the electronic device 100 further includes a support portion 4 disposed in the receiving cavity 11. The support portion 4 is fixedly connected to the housing portion 1 and includes a first side 41 and a second side 42 disposed opposite to each other. The side of the switch portion 2 facing the circuit board 31 abuts against the first side 41. The circuit board 31 is disposed on the second side 42. The support portion 4 is disposed between the switch portion 2 and the circuit board 31, and the switch portion 2 abuts against the support portion 4. Therefore, the support portion 4 can restrict the position of the switch portion 2 in the second direction Y, preventing the switch portion 2 from moving towards the circuit board 31 after being squeezed by external force, thus preventing damage to the circuit board 31 and the Hall unit 321. In embodiments where the circuit board 31 is a flexible circuit board, the circuit board 31 can be connected to the second side 42, thereby providing rigid support to the circuit board 31 through the support portion 4, ensuring that the position of the circuit board 31 is fixed.

[0041] The connection between circuit board 31 and the second side 42 can be achieved through methods such as bonding or screwing. Alternatively, it can be combined with... Figure 6 In some embodiments, the support portion 4 includes a limiting unit 48 disposed on the second side 42. The circuit board 31 includes a hole that mates with the limiting unit 48. When the circuit board 31 is connected to the second side 42, the limiting unit 48 passes through the hole. Thus, the relative positions of the circuit board 31 and the second side 42 in the first direction X and the third direction Z can be defined. In this embodiment, the circuit board 31 can be a rigid circuit board or a flexible circuit board. This application does not impose any limitations on this.

[0042] The connection between the bracket part 4 and the housing part 1 can be achieved by screwing as shown in the attached figure, or by means of snap-fit, magnetic attraction, welding, etc. This application does not limit this.

[0043] To enhance the protection of the magnetic component 322, optionally, the magnetic component 322 is spaced apart from the first side 41. The switch portion 2 abuts against the first side 41, meaning that the surface of the switch portion 2 facing the first side 41 has a protruding structure that abuts against the first side 41. Thus, when the switch portion 2 and the support portion 4 move relative to each other, the magnetic component 322 moves with the switch portion 2 but does not directly contact the first side 41. This arrangement protects the magnetic component 322, preventing wear caused by repeated tossing of the switch portion 2.

[0044] Combination Figure 2 and Figure 3In some embodiments, the support portion 4 includes a first protruding unit 43 and a second protruding unit 44. The first protruding unit 43 is disposed on a first side 41 and extends toward the switch portion 2. The second protruding unit 44 is disposed on the side of the first protruding unit 43 facing the switch portion 2. The switch portion 2 includes a recessed unit 21. The opening of the recessed unit 21 faces the first protruding unit 43, and the second protruding unit 44 extends into the recessed unit 21. Because the second protruding unit 44 extends into the recessed unit 21, the second protruding unit 44 can limit the distance between the switch portion 2 and the support portion 4, preventing the switch portion 2 from moving away from the support portion 4 and the electronic control portion 3 and leaving the receiving space. In addition, the cooperation between the second protruding unit 44 and the recessed unit 21 can also limit the translational direction of the switch portion 2.

[0045] like Figure 2 As shown, in some embodiments, the support portion 4 further includes a reinforcing unit 49 connecting the first protruding unit 43 and the first side 41. The reinforcing unit 49 can improve the connection strength between the first protruding unit 43 and the first side 41, preventing breakage at the connection point due to bending moment. This arrangement helps to improve the service life of the support portion 4.

[0046] Optionally, the switch unit 2 also includes a reset unit 22. The reset unit 22 is disposed in the recessed unit 21, with one end abutting against the wall of the recessed unit 21 and the other end abutting against the second protruding unit 44. The reset unit 22 is in a compressed state. When the switch unit 2 moves relative to the bracket unit 4, the reset unit 22 is further compressed, thereby continuously applying a reverse force to the second protruding unit 44. With this arrangement, the switch unit 2 can automatically reset after the user toggles and releases it. Furthermore, the elasticity of the reset unit 22 provides a better toggle feel when the user toggles the switch unit 2. The recessed unit 21 allows the reset unit 22 to be hidden, thus maintaining the reset effect of the switch unit 2 within the recessed unit 21 even during prolonged use of the electronic device 100 or when subjected to external vibration.

[0047] exist Figure 4 In the illustrated embodiment, the reset unit 22 includes two units because the second protruding unit 44 is centrally located within the recessed unit 21. By providing reset units 22 on both sides of the second protruding unit 44, it is ensured that the switch 2 can be smoothly reset when moved along both sides of the extending direction of the opening unit 12. In other embodiments, the second protruding unit 44 is located on one side of the recessed unit 21, in which case the switch 2 can only move in one direction, for example, pressing... Figure 4 The first direction X can be moved to the left or right. In this embodiment, there may be only one reset element.

[0048] In other alternative embodiments, the reset unit 22 may also be disposed on the outside of the switch part 2, with one end abutting against the switch part 2 and the other end abutting against the housing part 1. Alternatively, in embodiments without a reset unit 22, multiple grooves and protrusions are distributed between the housing part 1 and the switch part 2 along the moving direction of the switch part 2, thereby restricting the relative position between the housing part 1 and the switch part 2 by means of a snap-fit ​​mechanism, preventing the switch part 2 from moving back and forth within the opening unit 12.

[0049] Optionally, combined Figure 3 and Figure 5 In some embodiments, the support portion 4 further includes a third protruding unit 45 disposed on the first side 41. The third protruding unit 45 extends parallel to the moving direction of the switch portion 2 and abuts against the switch portion 2. Since the third protruding unit 45 extends along the moving direction of the switch portion 2, it can act as a guide rail, thereby guiding the translational movement of the switch portion 2. In embodiments where the support portion 4 includes a first protruding unit 43, a second protruding unit 44, and a third protruding unit 45, the switch portion 2 is disposed between the first protruding unit 43 and the third protruding unit 45. Thus, the first protruding unit 43 and the second protruding unit 44 can "clamp" the switch portion 2, further defining the moving direction of the switch portion 2.

[0050] The third protruding unit 45 may include multiple units as shown in the figure, or it may include only one unit; this application is not limited in this respect. Optionally, the switch part 2 includes a recessed mating unit 24, and the third protruding unit 45 is disposed in the mating unit 24. When the switch part 2 translates, the relative position of the mating unit 24 and the third protruding unit 45 changes. When the switch part 2 moves to its limit position, the third protruding unit 45 can abut against the wall 241 of the mating unit 24. In this way, the third protruding unit 45 can also limit the movement of the switch part 2 to its limit position.

[0051] refer to Figure 4 and Figure 6 In some embodiments, the support portion 4 includes a recessed unit 46 disposed on the second side 42. At least a portion of the circuit board 31 is disposed in the recessed unit 46, and the Hall unit 321 is disposed in the recessed unit 46. With this arrangement, the dimensions of the Hall unit 321, the circuit board 31, and the support portion 4 in the second direction Y are effectively controlled, thus optimizing the space for component arrangement in the accommodating cavity 11. Furthermore, the cooperation between the recessed unit 46 and the circuit board 31 can also enclose the Hall unit 321, thereby protecting the Hall unit 321 and ensuring the triggering accuracy and sensitivity of the multi-pole Hall switch 32.

[0052] To improve the sealing of the electronic device 100, the bracket portion 4 includes a sealing unit 47. The sealing unit 47 is disposed on the first side 41 and connected to the housing portion 1. This arrangement seals the gap between the bracket portion 4 and the housing portion 1, preventing external dust and liquid from entering the receiving cavity 11 through the gap and causing damage to the electronic control unit 3. The sealing unit 47 can be annular as shown in the figure. When the bracket portion 4 and the housing portion 1 are assembled, the user cannot observe or can only observe a small portion of the sealing unit 47 from the outside. In this embodiment, the switch portion 2 and the first side 41 directly abut against each other. In other embodiments, the sealing unit 47 can completely cover the first side 41. In this case, the switch portion 2 and the first side 41 abut against each other indirectly, i.e., through the sealing unit 47.

[0053] Optionally, a raised anti-slip unit 23 is provided on the side of the switch part 2 away from the circuit board 31. The anti-slip unit 23 increases the friction between the user's finger and the switch part 2, making it easier for the user to push the switch part 2 even when their hands are wet. In the embodiment shown in the attached drawings, the anti-slip unit 23 consists of three spaced-apart protrusions. In other embodiments, the number of protrusions may be greater, or the anti-slip unit 23 may be made of silicone material or the like, which is applied to the surface of the switch part 2. This application is not limited in this regard.

[0054] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. 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.
