[0035] In this embodiment, the encoding component 1 includes but is not limited to signal conversion devices such as encoders on electrical equipment; taking the encoder as an example, the encoding part 102 is the main part of the encoder, the connecting shaft 101 is the input shaft of the encoder, and the connecting shaft 101 can move along the axis direction of the connecting shaft 101 or drive the connecting shaft 101 to rotate around the axis of the connecting shaft 101. The base component 2 may include a main board 201 of the electrical equipment and a housing 202 for fixing the main board 201. The encoding part 102 of the encoding component 1 may be fixed to the main board 201 by welding or the like. The button component 3 may be fixed to the connecting shaft 101 of the encoding component 1 by locking, interference fit, snap connection, pin connection, bonding or the like.

[0036] In actual operation, the user can drive the connecting shaft 101 of the encoding component 1 to move axially relative to the base component 2 by pressing the button component 3, so that the signal input can be realized by the axial movement of the connecting shaft 101; the user can also drive the connecting shaft 101 of the encoding component 1 to rotate relative to the base component 2 by twisting the button component 3, so that the signal input can be realized by the rotation of the connecting shaft 101;

[0037] The key structure proposed in this embodiment includes a base assembly 2, a key assembly 3, a reflector 4 and a first light source 5; wherein the key assembly includes a first key housing 6 and a second key housing 7, wherein the first key housing 6 and the second key housing 7 are combined with a receiving chamber 301, and the first light source 5 is arranged in the receiving chamber 301; the first key housing 6 is made of a light-shielding material, and the second key housing 7 is made of a light-transmitting material; a reflector 4 is arranged between the second key housing 7 and the base assembly 2, and a preset gap is arranged between the reflector 4 and the second key housing 7; through the reflection effect of the reflector 4, the first light emitted by the first light source 5 passes through the second key housing 7, and is reflected by the reflector 4 and then emitted to the outside along the preset gap, that is, the first light is emitted from the bottom side of the key assembly 3. Different from the background technology in which the light is emitted from the key surface, in the present utility model, since the first light is emitted from the bottom side of the key assembly 3, it avoids the occurrence of poor light emission due to wear and aging of the key surface.

[0038] Further, see Figures 1 to 3 The reflector 4 is an annular structure; a reflective surface with an arc-shaped concave shape is provided on one side of the reflector 4 facing the key assembly 3, and the reflective surface is used to reflect the first light along the preset gap 14. The reflector 4 with an annular structure can reflect the first light in all directions, thereby improving the light emission effect.

[0039] Furthermore, an envelope portion 601 is provided at the edge of the first button housing 6, the envelope portion 601 extends toward the base assembly 2, and the envelope portion 601 covers the outer edge of the second button housing 7. Since the envelope portion 601 extends toward the base assembly 2, and the envelope portion 601 covers the outer edge of the second button housing 7 to form a water retaining portion, external rainwater or other liquids cannot enter the accommodating chamber 301 from the matching gap between the first button housing 6 and the second button housing 7 to cause a short circuit to the first light source 5.

[0040] Further, refer to Figure 3 , a light-transmitting channel 603 is provided inside the first button housing 6, and an indicator 10 is provided on the top of the first button housing 6, and the indicator 10 is made of a light-transmitting material; the base assembly 2 is provided with a second light source 11, and the second light emitted by the second light source 11 passes through the light-transmitting channel 603 in turn and irradiates the indicator 10. The second light emitted by the second light source 11 irradiates the indicator 10, wherein the indicator 10 can be designed as a graphic structure that enables the user to effectively distinguish the functions of each button, so that the operator can quickly press or twist the first button housing 6 corresponding to the system command at night or in scenes with insufficient brightness, thereby improving the convenience of operation.

[0041] Further, refer to Figure 3 and Figure 4 The second button housing 7 is provided with a limiting buckle 701, and the base assembly 2 is provided with a limiting flange 203; the limiting buckle 701 is used to buckle on the limiting flange 203 to prevent the button assembly 3 from moving away from the base assembly 2 along the axial direction of the connecting shaft 101.

[0042] like Figure 4 As shown, the limiting buckle 701 may include a vertical portion 7011 and a transverse portion 7012, one end of the transverse portion 7012 is connected to the lower end of the vertical portion 7011; an air avoidance area is provided below the limiting flange 203, and the lower end of the vertical portion 7011 extends into the air avoidance area so that the transverse portion 7012 can be buckled on the lower side of the limiting flange 203.

[0043] When the button assembly 3 rebounds a certain distance upward under the elastic force of the elastic member 13, the limit buckle 701 can be buckled onto the limit flange 203 to prevent the button assembly 3 from continuing to move upward. This can limit the upward movement of the button assembly 3 and prevent the button assembly 3 from moving upward beyond a preset range and causing damage to the encoding assembly 1 and other related devices.

[0044] Further, refer to Figure 3 The second button housing 7 is provided with a limiting protrusion 702; the limiting protrusion 702 is used to abut the base assembly 2 to prevent the button assembly 3 from approaching the base assembly 2 along the axial direction of the connecting shaft 101; the reflective member 4 is arranged between the limiting protrusion 702 and the limiting portion 204.

[0045] Illustratively, when the user presses the button assembly 3 to move downward a certain distance, the lower end of the limiting protrusion 702 can abut against the upper side surface of the base assembly 2 to prevent the button assembly 3 from continuing to move downward. This can limit the downward movement of the button assembly 3 and prevent the button assembly 3 from moving downward for a distance exceeding a preset range and causing damage to the encoding assembly 1 and other related devices.

[0046] Further, refer to Figure 3 and Figure 4 The base assembly 2 is provided with an annular limiting portion 204, and the reflector 4 is provided between the limiting protrusion 702 and the limiting portion 204. The limiting protrusion 702 and the limiting portion 204 are combined to limit the reflector 4, thereby preventing the reflector 4 from being displaced relative to the base assembly 2 or the second button housing 7, and ensuring the stability of light emission.

[0047] Further, refer to Figure 2 and Figure 3The key structure further includes an elastic member 13, which is disposed between the base assembly 2 and the limiting protrusion 702; the inner edge of the reflector 4 abuts against the elastic member 13, and the outer edge of the reflector 4 abuts against the inner edge of the limiting portion 204. The base assembly 2 is provided with an elastic member 13, and the limiting protrusion 702 is used to squeeze the elastic body, and the limiting protrusion 702 is used to move away from the base assembly 2 along the axial direction of the connecting shaft 101 under the elastic force of the elastic body. Specifically, the elastic body can be made of elastic materials such as foam, rubber, and spring steel.

[0048] When the user presses the button assembly 3 to move downward, the lower end of the limiting protrusion 702 will squeeze the elastomer downward, and the elastomer can produce a certain buffering effect on the pressed button assembly 3; and when the user removes the pressing force on the button assembly 3, the elastomer in the compressed state can push the limiting protrusion 702 upward based on its own elastic potential energy, thereby driving the button assembly 3 to rebound upward to the initial position, thereby realizing automatic resetting of the button assembly 3.

[0049] Further, the key assembly 3 includes a connecting bearing 8, the inner ring of the connecting bearing 8 is connected to the first key housing 6, and the outer ring of the connecting bearing 8 is connected to the second key housing 7. Among them, a rotating structure such as a ball or a needle is provided between the inner ring and the outer ring of the connecting bearing 8, and the inner ring and the outer ring can achieve relative rotation through the rotating structure, and the friction during the rotation process can be reduced through the rotating structure; the rotation axis of the connecting bearing 8 is coaxially arranged with the rotation axis of the connecting shaft 101. A shaft structure can be provided on the first key housing 6, and the shaft structure can be inserted into the inner ring of the connecting bearing 8 and have an interference fit with the inner ring, so that the first key housing 6 can rotate with the inner ring. A through hole structure or a concave cavity structure can be provided on the second key housing 7, wherein the cross-sectional profile of the hole part in the through hole structure should be adapted to the outer ring profile of the connecting bearing 8, and the cross-sectional profile of the cavity part in the concave cavity structure should also be adapted to the outer ring profile of the connecting bearing 8, so that the outer ring of the connecting bearing 8 can achieve an interference fit with the hole part of the through hole structure or the cavity part of the concave cavity structure through a hole-shaft matching method. Based on the above structural setting, the relative rotation between the inner ring and the outer ring of the connecting bearing 8 can be used to ensure that the rotation of the first button shell 6 is not affected by the second button shell 7; even if the second button shell 7 abuts against other structural parts and cannot rotate, the first button shell 6 can still rotate around the axis direction.

[0050] Illustratively, the first button housing 6 is located above the second button housing 7, and a reserved gap 12 can be set between the first button housing 6 and the second button housing 7 to ensure that the first button housing 6 can rotate relative to the second button housing 7 without friction or scratching with the second button housing 7. Furthermore, the reserved gap 12 is set between the envelope portion 601 and the outer edge of the second button housing 7; a connecting structure such as a rib and a buckle can be set on the second button housing 7. When the second button housing 7 moves up and down to a preset position relative to the base assembly 2 along the axial direction of the connecting shaft 101, the connecting structure is used to abut and cooperate with the base assembly 2 to prevent the second button housing 7 from continuing to move. The second button housing 7 moves to a preset position in a direction close to or away from the mainboard 201, and the connecting structure on the second button housing 7 abuts against the housing 202, thereby preventing the second button housing 7 from moving further close to or away from the mainboard 201, thereby preventing the connecting bearing 8 and the first button housing 6 from moving further, and thus limiting the first button housing 6. As mentioned above, by utilizing the relative rotation between the inner ring and the outer ring of the connecting bearing 8, when the connecting structure on the second button housing 7 abuts against the housing 202 and the second button housing 7 cannot rotate, the first button housing 6 can still rotate around the axis.

[0051] Based on the above arrangement, the user can rotate the button assembly 3 while pressing the button assembly 3, and the pressing operation and the rotating operation do not interfere with each other, thereby increasing the freedom of movement of the button assembly 3 and improving the applicability of the button assembly 3. The button assembly 3 can drive the connecting shaft 101 of the encoding assembly 1 to move axially or rotate axially, so as to realize signal input by means of the axial movement and rotation of the connecting shaft 101, thereby meeting the diversified control requirements of the device.

[0052] Optionally, refer to Figure 3 and Figure 5 , the button assembly 3 includes a connecting seat 9; the connecting seat 9 is connected to the connecting shaft 101, and the first button housing 6 is connected to the connecting seat 9;

[0053] The first button housing 6 has a first buckle portion 602, and the connecting seat 9 has a second buckle portion 901, wherein the first buckle portion 602 is interference-fitted with the inner ring of the connecting bearing 8 through a hole-shaft matching method, or the second buckle portion 901 is interference-fitted with the inner ring of the connecting bearing 8 through a hole-shaft matching method, or the first buckle portion 602 and the second buckle portion 901 are as follows. Figure 3As shown, it is simultaneously interference fit with the inner ring of the connecting bearing 8 through the hole-shaft matching method; in addition, the first buckle part 602 abuts against the end face of one side of the inner ring of the connecting bearing 8, and the second buckle part 901 abuts against the end face of the other side of the inner ring of the connecting bearing 8.

[0054] Specifically, the first buckle portion 602 can be configured as follows: Figure 2 The stepped structure shown in the figure has a first layer segment with a smaller width or a smaller diameter in the stepped structure that can be plugged and fitted into the inner ring of the connecting bearing 8 from top to bottom, and a second layer segment with a larger width or a larger diameter in the stepped structure that has a lower end face that can abut against the upper end face of the inner ring of the connecting bearing 8; it can be understood that the above-mentioned first layer segment can be set as an axial structure that is compatible with the inner ring of the connecting bearing 8, and the above-mentioned second layer segment can be set as an axial structure with a diameter larger than that of the first layer segment or a flange structure extending outward along the cylindrical surface of the first layer segment, which is not limited here.

[0055] Similarly, the second buckle portion 901 can be configured as follows Figure 2 The stepped structure shown in the figure has a third layer segment with a smaller width or a smaller diameter in the stepped structure which can be plugged and fitted into the inner ring of the connecting bearing 8 from bottom to top, and an upper end face of a fourth layer segment with a larger width or a larger diameter in the stepped structure can abut against a lower end face of the inner ring of the connecting bearing 8; it can be understood that the third layer segment can be set as an axial structure adapted to the inner ring of the connecting bearing 8, and the fourth layer segment can be set as an axial structure with a diameter larger than that of the third layer segment or a flange structure extending outward along the cylindrical surface of the third layer segment, which is not limited here.

[0056] By matching the connecting seat 9 with the first button housing 6 , the axial limitation of the connecting bearing 8 is conveniently achieved by utilizing the cooperation between the first buckling portion 602 , the second buckling portion 901 and the inner ring of the connecting bearing 8 .

[0057] Further, refer to Figure 3 The first button housing 6 includes a top housing 604 and a connecting column 605; the first end of the connecting column 605 is connected to the top housing 604, and the first buckle portion 602 is disposed at the second end of the connecting column 605. The second end of the connecting column 605 is provided with a connecting hole 606, and the connecting hole 606 has a threaded section 6061 and a light hole section 6062, which are arranged in sequence in a direction away from the connecting seat 9, and the connecting seat 9 is locked to the threaded section 6061 by a threaded fastener 15, and the light hole section 6062 extends to the top housing 604.

[0058] Specifically, the top shell 604 is a thin-walled structure and can be configured as follows: Figure 2The middle portion shown is dome-shaped and convex, and the connecting column 605 can be integrally formed with the middle portion of the top shell 604 by injection molding or the like; in this way, the top shell 604 with a larger coverage area can be convenient for users to press or twist, and the annular space formed between the lower side of the top shell 604 and the connecting column 605 can be used to accommodate the installation of the first light source 5 and other electronic components; further, the second button shell 7 can cover the annular space, so that a relatively closed accommodating chamber 301 can be enclosed and formed by the cooperation of the second button shell 7 and the top shell 604, thereby providing better protection for the first light source 5 and other electronic components installed in the accommodating chamber 301.

[0059] like Figure 3 As shown, the lower end of the connecting column 605 abuts against the upper end face of the connecting bearing 8 from top to bottom, and the connecting seat 9 abuts against the lower end face of the connecting bearing 8 from bottom to top. A threaded fastener 15 such as a bolt can be used to pass through the connecting seat 9 from bottom to top and screwed onto the threaded section 6061 of the connecting hole 606 at the lower end of the connecting column 605. Then, by screwing the threaded fastener 15, the screw head part of the threaded fastener 15 can be used to push the connecting seat 9 to move in the direction close to the connecting column 605. Finally, the inner ring of the connecting bearing 8 can be clamped by the first buckle part 602 and the second buckle part 901, thereby realizing the connection and fixation between the first button housing 6, the connecting bearing 8 and the connecting seat 9.

[0060] Understandable, reference Figure 2 and Figure 3 Since the connecting seat 9 is arranged between the second light source 11 and the light-transmitting channel 603, in order to ensure that the second light emitted by the second light source 11 can penetrate the connecting seat 9 and illuminate the light-transmitting channel 603, the connecting seat 9 should be made of a light-transmitting material to ensure that the second light can smoothly penetrate the connecting seat 9.

[0061] Further, refer to Figure 3 and Figure 5 The second button housing 7 is provided with a connecting boss 703, and the connecting boss 703 has a connecting ring 7031 and a transverse flange 7032. The connecting ring 7031 extends along the axial direction of the connecting bearing 8, and the transverse flange 7032 is arranged on the inner ring surface of the connecting ring 7031. The inner ring surface of the connecting ring 7031 is interference fit with the outer ring of the connecting bearing 8, and the transverse flange 7032 abuts against at least one side end surface of the outer ring of the connecting bearing 8.

[0062] Based on the above arrangement, the axial limitation of the second button housing 7 can be conveniently achieved by utilizing the cooperation between the transverse flange 7032 and the outer ring of the connecting bearing 8, thereby preventing the second button housing 7 from axially sliding relative to the connecting bearing 8 during subsequent use.
