Detailed implementation manners

[0058] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0060] As Figures 1-7 shown, in this embodiment, a button component is provided, including: a housing 1, a button structure, and a locking structure.

[0061] At least one first button position 11 is provided on the housing 1, and an opening is provided at at least one end of the housing 1; at least one second button position 41 is provided on the button structure, and the button structure is adapted to be inserted into or removed from the housing 1 through the opening, and has an installation position where the second button position 41 is correspondingly arranged with the first button position 11; the locking structure is adapted to lock the position of the button structure when the button structure is in the installation position.

[0062] By providing a first key position 6 on the housing 1 and a second key position 41 on the key structure, when the key structure is inserted into the housing 1 through the opening at the end of the housing 1 during assembly, through the alignment of the two key positions 5, it can be clearly known that the key structure has been assembled in place to the installation position. By providing a locking structure, the assembled key structure can be locked to prevent the key structure from falling off the housing 1. The key component provided by the present invention enables the key structure to be directly assembled through the opening at the end of the housing 1 without disassembling the housing 1 again, making the disassembly and assembly of the key structure relatively simple. At the same time, since there is no need to disassemble the housing 1, the key structure can also be assembled on an integrally formed housing 1, with a wider range of applicability.

[0063] The locking structure in this embodiment includes: a positioning structure provided on the inner peripheral wall of the housing 1, adapted to radially limit the key structure; a limiting structure adapted to axially limit the key structure when the key structure is in the installation position. By setting the locking structure to include a positioning structure for radially limiting the key structure and a limiting structure for axially limiting the key component, the key structure is assembled more firmly, preventing its movement in the axial and radial directions.

[0064] The key structure in this embodiment is slidably connected to the positioning structure. By slidably connecting the key structure to the positioning structure, the assembly of the key structure and the positioning structure is made simpler. As an alternative embodiment, it can also be that the key structure and the positioning structure are movably connected in other ways, enabling the key structure to be assembled onto the positioning structure.

[0065] As Figure 3 shown, there are many specific forms of the positioning structure. The positioning structure in this embodiment includes at least one positioning groove 14. The positioning groove 14 includes: a groove bottom wall adapted to limit the side of the key structure facing away from the first key position 6; a groove side wall arranged at an angle to the groove bottom wall, adapted to limit the side of the key structure adjacent to the second key position 41. By setting the positioning groove 14 to include a groove bottom wall and a groove side wall, the side and end of the key structure can be limited, making the limitation of the key structure more firm.

[0066] Specifically, the positioning structure in this embodiment includes two positioning grooves 14, and the two positioning grooves 14 are arranged oppositely. During assembly, the two oppositely arranged sides of the key structure are respectively placed on the two oppositely arranged positioning grooves 14. As an alternative embodiment, it can also be that the positioning structure is a single positioning groove 14, with one groove side wall provided on the inner peripheral wall of one side and the other groove side wall provided on the inner peripheral wall of the opposite side, and the two groove side walls are connected together by the groove bottom wall.

[0067] There are many specific forms of the limiting structure. The limiting structure in this embodiment includes: at least one convex edge 46 extending outward from the side of the key structure adjacent to the second key position 41, and adapted to abut against the end of the positioning structure when the key structure is in the installation position. By providing the convex edge 46 extending outward on the side of the key structure, when the key structure is assembled inward from the opening at the end of the housing 1, the convex edge 46 abuts against the end of the positioning structure, indicating that the key structure has been assembled to the installation position, and the key structure can be well limited in the axial direction.

[0068] Specifically, there are two protrusions 46 in this embodiment, which extend outward from the two sides of the key structure respectively. The limiting structure in this embodiment also includes a positioning rib 15, which is provided on the end of the positioning structure and abuts against the protrusion 46 when the key structure is in the installation position. As a convertible embodiment, there may be one or more protrusions 46. As a convertible embodiment, there may be no positioning rib 15 on the positioning structure, or a positioning groove 14 is provided on the positioning structure. As long as the protrusion 46 can abut against the positioning structure when the key structure is in the installation position, it indicates that the key structure has been assembled in place.

[0069] like Figure 4 As shown, the limiting structure in this embodiment includes a limiting body 2, a limiting groove 21 is provided on the peripheral wall of the limiting body 2, and a limiting rib 16 is provided on the positioning structure to match the limiting groove 21. By providing the limiting groove 21 and the limiting rib 16 that are assembled with each other on the limiting body 2 and the positioning structure, the assembly method of the limiting body 2 and the positioning structure is simplified. As a convertible implementation method, it is also possible that the limiting rib 16 is provided on the peripheral wall of the limiting body 2, and the limiting groove 21 that is provided on the positioning structure to match the limiting rib 16.

[0070] The end of the key structure in this embodiment is also connected to a limiting portion 45, and a limiting cavity 23 is provided on the limiting body 2. The limiting portion 45 is axially assembled inside the limiting cavity 23, and the limiting portion 45 is radially assembled in the clearance space 13 of the positioning structure. The clearance space 13 is surrounded by the side walls extending away from the end of the bottom wall of the two positioning grooves 14 away from the inner peripheral wall in the direction away from the side wall. By connecting the limiting portion 45 to the end of the key structure and providing the limiting cavity 23 on the limiting body 2, when the limiting body 2 limits the case assembly, the limiting portion 45 is assembled inside the limiting cavity 23, which can make the key structure more firmly limited.

[0071] In order to make the limit more secure, at least one first mounting hole 12 is formed on the side wall of the clearance space 13 in this embodiment, and a second mounting hole 22 is formed on the limit body 2 to cooperate with the first mounting hole 12; the limit structure also includes a fastener, which is suitable for passing through the first mounting hole 12 and the second mounting hole 22 to fix the limit body 2 to the shell 1. By providing the fastener, the fixation of the limit body 2 to the shell 1 is more secure, and the limit body 2 to the key structure is also more secure.

[0072] Specifically, in this embodiment, there are two first mounting holes 12 and two second mounting holes 22, and the fasteners are screws. In another embodiment, there can be one first mounting hole 12 and one second mounting hole 22, or more, and the fasteners can also be bolts or other fasteners.

[0073] The housing 1 in this embodiment is an integrally formed structure. By setting the housing 1 as an integrally formed structure, the housing 1 of the key component does not have a dividing line between the front and rear housings, making the overall appearance more beautiful and enhancing the recognition of the appearance. As a convertible implementation, the housing 1 may also be a front housing and a rear housing that are separately set.

[0074] In this embodiment, there are three first key positions 6 and three second key positions 41. As a changeable implementation, the number of the first key positions 6 and the second key positions 41 can also be two or other numbers, which can be set according to actual needs.

[0075] In this embodiment, one end of the housing 1 is provided with an opening, and the key structure is disassembled and assembled through the opening of the end. As a changeable embodiment, both ends of the housing 1 can also be provided with openings.

[0076] The key structure in this embodiment is a key assembly formed by connecting multiple components, specifically including: a bracket 4, on which a second key position 41 is provided; a circuit board 3, which is clamped with the bracket 4, and a button 31 is provided at a position of the circuit board 3 corresponding to the second key position 41, and the button 31 is arranged in a one-to-one correspondence with the second key position 41. By clamping the bracket 4 with the circuit board 3, the assembly method of the bracket 4 and the circuit board 3 is simpler and the cost is lower.

[0077] like Figure 6 As shown, a mounting cavity 44 for mounting the circuit board 3 is formed on the bracket 4 in this embodiment, and at least one blocking portion is provided on the side of the bracket 4 close to the circuit board 3, which is suitable for limiting the movement of the circuit board 3 in a direction away from the second key position 41. By providing the blocking portion on the bracket 4, the circuit board 3 can be prevented from moving in a direction away from the second key position 41 when the circuit board 3 and the bracket 4 are assembled.

[0078] Specifically, the blocking parts in this embodiment include a first blocking part 43 provided on the side and a second blocking part 47 provided at the end. Two first blocking parts 43 are provided at one end of the bracket 4. The first blocking part 43 is a convex block extending inward from the end. A plurality of second blocking parts 47 are provided on the side of the bracket 4. The second blocking part 47 is a buckle. By providing blocking parts on both the side and the end of the bracket 4, the limit on the circuit board 3 can be made more firm. As a variable implementation method, it can also be that the specific number of blocking parts is set according to the actual situation.

[0079] To prevent the circuit board 3 from moving into the installation cavity 44 of the bracket 4, a convex part 42 is provided on the side of the bracket 4 away from the circuit board 3, which is suitable for restricting the circuit board 3 from moving in the direction close to the second key position 41. The convex part 42 in this embodiment is four convex columns. As a variable implementation method, the convex part 42 can also be a convex block, and the quantity can be set according to actual needs.

[0080] As Figure 5 shown, to facilitate the assembly of the bracket 4 and the circuit board 3, anti-fooling structures 32 are also provided at both ends of the circuit board 3 in this embodiment, so as to distinguish the two ends of the bracket 4 and the circuit board 3. One end of the circuit board 3 with a large anti-fooling structure 32 is adapted to the end of the bracket 4 where the blocking part is provided, and one end of the circuit board 3 with a small anti-fooling structure 32 is adapted to the end of the bracket 4 where the convex edge 46 and the limited position part 45 are connected.

[0081] The first key position 6 in this embodiment is a key hole, and the second key position 41 is a key hole. The key 5 of the key structure is snap-fitted with the second key position 41, and is suitable for when the key structure is in the installation position, the key 5 is inserted into the second key position 41 through the key hole and contacts the button 31 on the circuit board 3. By setting the first key position 6 as a key hole, the key 5 can be directly assembled from the key hole on the outer shell 1. The key 5 is snap-fitted with the second key position 41, making the assembly method of the key 5 simpler. As a variable implementation method, the first key position 6 is a key 5 groove.

[0082] As Figure 6 and Figure 7 shown, specifically, a plurality of buckles 48 are provided on the second key position 41 in this embodiment, and card holes 51 are provided on the key 5 that are arranged in cooperation with the buckles 48. As a variable implementation method, it can also be that the buckles 48 are provided on the key 5 and the card holes 51 are provided on the second key position 41; or the quantity of the buckles 48 and the card holes 51 can be set according to actual needs.

[0083] The key 5 in this embodiment is a mechanical key. As a variable implementation method, the key 5 can also be a touch-type key.

[0084] In this embodiment, a device with a key component is further provided, including the key component as described above.

[0085] Specifically, the device with a key component in this embodiment is an electric fan. As a variant embodiment, it may also be that the device with a key component is any electrical appliance that needs to be controlled by means of a key 5.

[0086] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
