Description

Technical Field

[0001] The present invention relates to the technical field of button structures, and in particular to a button structure, a handle assembly, and a vacuum cleaner. Background Art

[0002] A microswitch is a switch that rapidly connects or disconnects the fixed and moving contacts at its ends by applying an external mechanical force through a transmission element. It can usually be activated with minimal force. To trigger the microswitch, a pushbutton structure is typically provided to facilitate manual operation. However, in some structures with limited installation space, a rational design is required to ensure both secure installation and smooth triggering of the microswitch. Furthermore, conventional pushbuttons often utilize rotational motion, which can easily produce unusual noises due to the misalignment of the spring during compression and release, reducing the user experience. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the key structure adopts the form of rotational motion and is prone to causing abnormal noise, thereby providing a key structure that reduces the probability of abnormal noise and improves the smoothness of use.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The key structure provided by the present invention operates the key body movably arranged on the main frame, so that the key body turns on the micro switch in a pressed state and turns off the micro switch in a non-pressed state, thereby enabling the micro switch and the key body to be reasonably arranged so that the micro switch and the key body can be placed relative to each other in the up-down direction instead of in the front-back direction, thereby greatly saving space occupied along the movement direction of the key body and reasonably utilizing the space of the key body along the up-down direction; by changing the control mode and layout form, space is saved and the control effect is ensured, thereby facilitating application in a working environment where the space along the movement direction of the key body is relatively cramped.

[0028] 2. The key structure provided by the present invention is such that the key body is movably arranged on the main bracket via the guide column, and the key body is suitable for translational movement along the length direction of the guide column, thereby limiting the length direction of the guide column as the movement direction of the key body, ensuring that the key body can translate without rotation, and ensuring that the key body is in contact with the spring of the micro switch without loosening.

[0029] 3. In the key structure provided by the present invention, the reset spring extends or contracts in a length direction parallel to the guide column, thereby making the reset spring extend and retract more smoothly, reducing the failure rate, reducing the occurrence of abnormal noise, and avoiding defects such as abnormal noise caused by the misalignment of the spring movement process during the rotation movement of conventional keys.

[0030] 4. The button structure provided by the present invention forms a pressure-equalizing hole by penetrating the main body bracket along the length direction of the guide hole, so that when the guide column moves in the guide hole, the internal and external air pressure can be balanced, thereby ensuring the smooth operation of the guide column, avoiding the difficulty in pressing the guide column due to the inability to eliminate the air pressure, and improving the user experience.

[0031] 5. The key structure provided by the present invention has two sets of guide columns and guide holes that cooperate with each other, thereby ensuring that the key body moves relative to the main body bracket along the length direction of the guide columns, ensuring the consistency of the movement path during repeated pressing, and improving the smoothness of the movement. The two guide columns are arranged in parallel, so that the movement path is not easy to deviate, and it is easy to ensure the centering of the reset spring.

[0032] 6. The key structure provided by the present invention, by arranging the spring piece on the side wall of the micro switch away from the pressing surface of the key body, makes the space occupied by the micro switch body and the main body of the key body overlap in the up and down directions, thereby reducing the space occupied along the movement direction of the key body, and reasonably utilizing the space while ensuring the control effect.

[0033] 7. The key structure provided by the present invention connects the key body to the main frame through correspondingly arranged button clips and button slots to prevent them from detaching; and a clearance cavity is formed in the button slot along the movement direction of the key body, so that when the key body is pressed, the button clip moves with the key body, and the clearance cavity makes way for the movement of the button clip, thereby ensuring firm fixation and preventing detachment, avoiding movement interference, and making relative movement smoother.

[0034] 8. In the button structure provided by the present invention, when the button buckle returns to its original position after being pressed, the button slot can limit the button buckle to prevent it from falling out, and the button slot can play a good positioning role in the return movement distance of the button buckle, thereby ensuring the relative position of the pressure rod and the spring sheet, and avoiding damage to the spring sheet when it is subjected to excessive pressure.

[0035] 9. The key structure provided by the present invention reduces the space occupied in the width direction of the main bracket by arranging the micro switch and the key body along the up and down directions on the main bracket, rationally utilizes the length of the main bracket, and saves space occupied along the movement direction of the key body.

[0036] 10. The handle assembly provided by the present invention arranges the button structure inside the handle assembly, and preferably arranges the button body and the micro switch along the length direction of the handle assembly, so that the button body turns on the micro switch when pressed, and turns off the micro switch when not pressed, so that the micro switch and the button body can be reasonably arranged, so that the micro switch and the button body can be placed relative to each other in the up and down directions, without having to be placed in the front and back directions, making it convenient to arrange the button structure inside the handle assembly, greatly saving space occupied along the movement direction of the button body, without expanding the diameter of the handle assembly, saving space, and ensuring the control effect.

DETAILED DESCRIPTION

[0048] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] 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.

[0052] Example 1

[0053] Combine Figures 1-8 As shown, the key structure provided in this embodiment includes:

[0054] Main frame b10;

[0055] A micro switch b20 is mounted on the main frame b10; and

[0056] The button body b30 is movably arranged on the main frame b10, and is suitable for turning on the micro switch b20 in a pressed state and turning off the micro switch b20 in a non-pressed state.

[0057] Combine Figure 7 , Figure 8 As shown, unlike the traditional microswitch control form, the microswitch b20 provided in this embodiment is controlled by the button body b30. When the button body b30 is pressed, the spring b21 of the microswitch b20 moves away from the main body of the microswitch, and the spring b21 releases the pressure on the operating button b23, so that the dynamic reed b24 inside the microswitch contacts the normally closed contact b25; when the button body b30 is in the non-pressed state, the spring b21 of the microswitch b20 approaches the main body of the microswitch, and the spring b21 presses the operating button b23, so that the dynamic reed b24 inside the microswitch contacts the normally open contact b26.

[0058] The key structure provided in this embodiment operates the key body b30 which is movably arranged on the main bracket b10, so that the key body b30 turns on the micro switch b20 in a pressed state and turns off the micro switch b20 in a non-pressed state, thereby enabling the micro switch b20 and the key body b30 to be reasonably arranged, so that the micro switch b20 and the key body b30 can be placed relative to each other in the up and down directions, without having to be placed in the front and back directions, thereby greatly saving the space occupied along the movement direction of the key body b30 and reasonably utilizing the space of the key body b30 along the up and down directions; by changing the control mode and layout form, space is saved, the control effect is guaranteed, and it is convenient for application in a working environment where the space along the movement direction of the key body b30 is relatively cramped.

[0059] Preferably, the micro switch b20 is further connected to a wire b40, and the wire b40 is suitable for electrically connecting the micro switch b20 directly or indirectly to the control module.

[0060] Specifically, the button body b30 includes: at least one guide column b32, the button body b30 is movably arranged on the main bracket b10 via the guide column b32, and the button body b30 is suitable for moving horizontally along the length direction of the guide column b32.

[0061] Preferably, the guide column b32 is constructed as a columnar structure.

[0062] The key structure provided in this embodiment is such that the key body b30 is movably arranged on the main bracket b10 via the guide column b32, and the key body b30 is suitable for translation along the length direction of the guide column b32, thereby limiting the length direction of the guide column b32 as the movement direction of the key body b30, ensuring that the key body b30 translates without rotation, and ensuring that the key body b30 does not loosen in contact with the spring of the micro switch b20.

[0063] Specifically, a guide hole b11 is provided on the main support b10 corresponding to the guide column b32, and the guide column b32 is installed with a transition fit or a clearance fit with the guide hole b11.

[0064] Through the cooperation between the guide hole b11 and the guide column b32, the button body b30 can move smoothly on the main bracket b10 and play a guiding role.

[0065] Specifically, the button structure further includes: a return spring b50, which is arranged between the button body b30 and the main frame b10 and is suitable for extending or contracting in parallel with the length direction of the guide column b32.

[0066] Preferably, the return spring b50 is in the form of a coil spring.

[0067] Compared with the key body b30 that adopts a rotating form, the return spring b50 of this embodiment does not need to expand and contract along an arc path, thereby avoiding the misalignment of the return spring b50 due to the different degrees of compression on the opposite sides of the spring during movement, thereby reducing the generation of abnormal noise.

[0068] In the key structure provided by this embodiment, the return spring b50 extends or contracts along the length direction parallel to the guide column b32, so that the return spring b50 can extend and retract more smoothly, reduce the failure rate, reduce the occurrence of abnormal noise, and avoid defects such as abnormal noise caused by the misalignment of the spring movement process during the rotation movement of conventional keys.

[0069] Preferably, the return spring b50 performs telescopic movement along its own axis, and the axis of the return spring b50 is parallel to the length direction of the guide column b32.

[0070] Specifically, a spring top column is further provided on the button body b30 and / or the main body bracket b10, and the spring top column is suitable for abutting against the return spring b50.

[0071] Preferably, the main support b10 is provided with a first spring top column b15, and the button body b30 is provided with a second spring top column b34. The first spring top column b15 and the second spring top column b34 are arranged in an aligned manner along the extension and contraction direction of the return spring b50, ensuring that the return spring b50 does not deviate during extension and contraction. It should be noted that the alignment of the first spring top column b15 and the second spring top column b34 along the extension and contraction direction of the return spring b50 means that the axis of the return spring b50 coincides with the central axis of the first spring top column b15 and the second spring top column b34, thereby ensuring that the return spring b50 moves along its own axis.

[0072] In some embodiments, the first spring top column b15 and the second spring top column b34 are arranged in the middle position of two or more guide columns b32, so that the movement axis of the return spring b50 is parallel to the axis of the two or more guide columns b32.

[0073] In some other embodiments, the button structure may include a plurality of return springs b50, and correspondingly, the number of the first spring top column b15 and the second spring top column b34 may also be multiple.

[0074] In some other embodiments, the first spring top column b15 and the second spring top column b34 can also be arranged at the root positions of the guide column b32 and the guide hole b11, respectively, and are preferably arranged at the root position of the outer surface of the guide column b32 and the root position surrounding the outside of the guide hole b11.

[0075] Specifically, the main support b10 further includes: a pressure equalizing hole b12, which is formed by the guide hole b11 penetrating the main support b10 along the length direction.

[0076] The key structure provided in this embodiment forms a pressure-equalizing hole b12 through the main frame b10 along the length of the guide hole b11. This allows the guide post b32 to balance the internal and external air pressures when it moves within the guide hole b11, ensuring smooth operation of the guide post b32 and avoiding the difficulty of pressing the guide post b32 due to the inability to dissipate air pressure, thereby improving the user experience. The pressure-equalizing hole b12 is constructed as a hole-shaped structure and is used to balance the internal and external air pressures of the guide hole b11.

[0077] Specifically, two guide posts b32 are provided on the button body b30, and two guide holes b11 are correspondingly provided on the main frame b10, and the two guide posts b32 are arranged in parallel.

[0078] The key structure provided in this embodiment has two sets of guide columns b32 and guide holes b11 that cooperate with each other, thereby ensuring that the key body b30 moves relative to the main bracket b10 along the length direction of the guide columns b32, ensuring the consistency of the movement path during repeated pressing, and improving the smoothness of the movement. The two guide columns b32 are arranged in parallel, so that the movement path is not easy to deviate, and it is easy to ensure that the return spring b50 moves along its own axial direction.

[0079] Specifically, the button body b30 includes a pressure rod b31, which moves with the button body b30 and is suitable for triggering the spring b21 of the micro switch b20.

[0080] Specifically, the spring b21 is arranged on the side wall of the micro switch b20 away from the pressing surface of the button body b30.

[0081] Preferably, a hook portion is provided on the pressure rod b31, which abuts against the spring piece b21 through the hook portion, and preferably, when the button body b30 is pressed, the hook portion relaxes the tensioning effect on the spring piece b21, and when the button body b30 is not pressed, the hook portion tightens the spring piece b21 and makes the spring piece b21 close to the main structure of the micro switch b20.

[0082] The key structure provided in this embodiment arranges the spring piece b21 on the side wall of the micro switch b20 away from the pressing surface of the key body b30, so that the space occupied by the micro switch body and the main body of the key body b30 in the up and down directions overlap, thereby reducing the space occupied along the movement direction of the key body b30 and reasonably utilizing the space while ensuring the control effect.

[0083] Preferably, the projection of the button body b30 in the up and down directions covers the micro switch b20.

[0084] Specifically, when the button body b30 is in the pressed state, the pressure rod b31 drives the spring b21 away from the microswitch body and turns on the microswitch b20; when the button body b30 is in the non-pressed state, the pressure rod b31 drives the spring b21 close to the microswitch body and turns off the microswitch b20.

[0085] Specifically, a button buckle b33 is provided on the button body b30; a button card slot is provided on the main frame b10 corresponding to the button buckle b33, and the button card slot is suitable for clamping the button buckle b33.

[0086] Specifically, the button slot is formed with a make way cavity along the movement direction of the button body b30, and the make way cavity is suitable for making way for the movement of the button buckle b33.

[0087] The key structure provided in this embodiment connects the key body b30 with the main bracket b10 through the correspondingly arranged button clip b33 and button slot to prevent them from detaching; and a yield cavity is formed in the button slot along the movement direction of the key body b30, so that when the key body b30 is pressed, the button clip b33 moves along with the key body b30, and the yield cavity makes way for the movement of the button clip b33, thereby ensuring firm fixation and preventing detachment, avoiding movement interference, and making relative movement smoother.

[0088] In the key structure provided by this embodiment, when the button buckle b33 returns to its original position after being pressed, the button slot can limit the button buckle b33 to prevent it from falling out, and the button slot can play a good positioning role in the return movement distance of the button buckle b33, thereby ensuring the relative position of the pressure rod b31 and the spring piece b21, and avoiding damage to the spring piece b21 when it is subjected to excessive pressure.

[0089] Specifically, the main bracket b10 includes: a positioning column b13, which is suitable for plugging and matching with the positioning hole on the micro switch b20, and enables the micro switch b20 to rotate and / or move horizontally only along the axial direction of the positioning column b13.

[0090] Specifically, the main bracket b10 further includes: a micro switch buckle b14, which is snap-connected to the micro switch b20 and is suitable for limiting the rotation and / or translation of the micro switch b20 along the axial direction of the positioning column b13.

[0091] As a variation, the main bracket b10 can be connected to the micro switch b20 in a variety of ways, such as slot insertion, screw fixing, bonding, etc., which will not be described in detail here.

[0092] Specifically, the micro switch b20 and the button body b30 are arranged on the main bracket b10 along the up and down directions.

[0093] The key structure provided in this embodiment reduces the space occupied in the width direction of the main bracket b10 by arranging the micro switch b20 and the key body b30 on the main bracket b10 in the up and down directions, reasonably utilizes the length of the main bracket b10, and saves the space occupied along the movement direction of the key body b30.

[0094] Example 2

[0095] This embodiment provides a handle assembly, including: the button structure as described above.

[0096] Preferably, the handle assembly is convenient for the user to hold, and a button structure is provided on the handle assembly to facilitate the user to operate.

[0097] The handle assembly provided in this embodiment arranges the button structure inside the handle assembly, and preferably arranges the button body b30 and the micro switch b20 along the length direction of the handle assembly, so that the button body b30 turns on the micro switch b20 when pressed, and turns off the micro switch b20 when not pressed, so that the micro switch b20 and the button body b30 can be reasonably arranged, so that the micro switch b20 and the button body b30 can be placed relative to each other in the up and down directions, without having to be placed in the front and back directions, so that the button structure can be conveniently arranged inside the handle assembly, which greatly saves space along the movement direction of the button body b30, does not need to expand the diameter of the handle assembly, saves space, and ensures the control effect.
