Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and more specifically, to a remote control key. Background Art

[0002] The remote control key of an automobile refers to a key that can perform actions such as opening or locking the door at a distance without inserting it into the keyhole. Its working principle is usually as follows: when the key plate of the key structure of the remote control key is pressed to trigger the micro switch below, a weak radio wave will be emitted inside the remote control key, which is received by the automobile antenna, and finally actions such as locking or unlocking the door are controlled.

[0003] In some existing remote control keys, in order to reduce the gap between adjacent keys, the key plates of adjacent key structures are often non-independent integral key plate structures, that is, multiple trigger posts for triggering corresponding micro switches are provided on the integral key plate. For example, a rotating shaft is provided at the center position of the inner side wall of the integral key plate to form a seesaw-like structure, and trigger posts are respectively provided at opposite ends of the integral key plate. When the trigger post at one end of the key plate is pressed by a certain stroke to trigger the corresponding micro switch, the trigger post at the other end will tilt upward by the same stroke to ensure that the two trigger posts do not trigger the corresponding micro switches simultaneously. However, this will also cause the edge of the key plate at the other end that is not pressed to protrude significantly from the surrounding housing, resulting in a significant mismatch with the surrounding housing; moreover, in order to ensure that the movement of this seesaw-like key plate with the center position as the fulcrum is not interfered by the surrounding housing, a large gap needs to be left between the edge of the key plate when not pressed and the surrounding housing. As a result, external impurities easily enter the gap, and it is not aesthetically pleasing. The existence of the large gap also leads to an obvious mismatch between the key plate and the surrounding housing, with poor consistency. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] To solve the above problems, the utility model provides a remote control key, including a main body part and a first key plate. A groove is provided on one side surface of the main body part. The first key plate is located in the groove, and a rigid support member, a first trigger post, and a second trigger post are respectively provided on the side facing the bottom wall of the groove. The rigid support member is located at one end of the first key plate along a first set line. The first trigger post and the second trigger post are respectively located on both sides of the first set line. The end of the rigid support member is ball-hinged to the bottom wall of the groove. The projection positions of the first trigger post and the second trigger post on the first set line are both spaced from the position where the rigid support member is located.

[0006] A remote control key provided by the present utility model has, compared with the prior art, the following technical effects but is not limited to:

[0007] The first key board placed in the groove can be a symmetrical structure, the first setting line can be its axis of symmetry, a rigid support member is arranged at one end of the first key board along the axis of symmetry, for example, the rear end, and is ball-joint connected to the bottom wall of the groove through the rigid support member. The axis of symmetry of the first key board can divide the first key board into a left half and a right half. The first trigger post can be arranged at the left half of the first key board, and the second trigger post can be arranged at the right half of the first key board. Moreover, the projection positions of the first trigger post and the second trigger post on the axis of symmetry are respectively set at intervals from the position where the rigid support member is located. That is to say, the first trigger post is located in front of the left of the rigid support member, and the second trigger post is located in front of the right of the rigid support member.

[0008] In this way, when the left front part of the first key board is pressed and rotates relative to the rigid support member, the downward movement stroke of the first trigger post in front of the left of the rigid support member can be more than the downward movement stroke of the second trigger post in front of the right of the rigid support member. Therefore, when the first trigger post descends to a preset stroke and triggers the corresponding micro switch, the second trigger post will not trigger the corresponding micro switch at this time; similarly, when the right front part of the first key board is pressed and rotates relative to the rigid support member, the downward movement stroke of the second trigger post in front of the right of the rigid support member can be more than the downward movement stroke of the first trigger post in front of the left of the rigid support member. Therefore, when the second trigger post descends to a preset stroke and triggers the corresponding micro switch, the first trigger post will not trigger the corresponding micro switch at this time, thereby realizing that the first trigger post and the second trigger post will not trigger the corresponding micro switches simultaneously.

[0009] Moreover, the rigid support member used as the rotation fulcrum is designed at the rear end of the first key board along the axis of symmetry. When the left front part of the first key board is pressed, even if the right rear part symmetrical to the left front part relative to the fulcrum will be lifted, because the rigid support member (fulcrum) is arranged at the rear end of the first key board and is very close to the rear end edge, that is, the force arm is very short, so the right rear part of the fulcrum will basically not have an obvious lift; similarly, when the right front part of the first key board is pressed, the left rear part of the fulcrum will basically not have an obvious lift; therefore, the edges of the entire first key board will not have an obvious lift, and the lift degree can even be ignored, ensuring a high consistency between the edge of the first key board and the main body part; in addition, compared with the prior art in which the rotation fulcrum is designed in the middle of the key board, the edge of the first key board of the present utility model does not need to have a large gap with the side wall of the surrounding groove when not pressed, foreign impurities are not easy to enter, the overall shape is more beautiful, and the consistency and matching degree between the first key board and the main body part are better.

[0012] Furthermore, a buckle is protruded from a side of the first key plate toward the bottom wall of the groove, and a plurality of the buckles are respectively located on both sides of the first setting line. A card slot is provided on the bottom wall of the groove, and the buckle is engaged with the card slot.

[0014] Furthermore, a spherical groove is provided on the bottom wall of the groove, and the end of the rigid support member is supported in the spherical groove, and the end of the rigid support member matches the shape of the spherical groove.

[0015] Furthermore, the remote control key also includes a separator, a notch is provided along the first setting line at one end of the first key panel away from the rigid support member, a connecting line between the first trigger column and the second trigger column intersects with the notch, at least a portion of the separator is located in the notch, and the separator is connected to the main body.

[0017] Alternatively, and / or, the remote control key further includes a third button board. One end of the first button board away from the rigid support member includes two setting sides arranged at an angle, and the two setting sides are symmetrically arranged with respect to the first setting line. The third button board is located between the two setting sides and the side wall of the groove. The separating member has a Y-shaped structure and includes three separating strips. One of the separating strips is located in the notch groove, and the other two separating strips are respectively located at the gaps between the two setting sides and the third button board.

[0018] Further, the main body portion has a hollow cavity, and the remote control key further includes a circuit board located in the hollow cavity.

[0033] At the same time, it should be noted that the meanings represented by the foregoing X-axis, Y-axis and Z-axis are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] Refer to Figure 1 、Figures 3 - 5 , a remote control key according to an embodiment of the present utility model includes a main body portion 1 and a first button board 2. A groove 1121 is provided on one side surface of the main body portion 1. The first button board 2 is located in the groove 1121, and a rigid support member 23, a first trigger post 21, and a second trigger post 22 are respectively provided on a side facing the bottom wall of the groove 1121. The rigid support member 23 is located at one end of the first button board 2 along a first set line. The first trigger post 21 and the second trigger post 22 are respectively located on both sides of the first set line. The end of the rigid support member 23 is ball-hinged to the bottom wall of the groove 1121. The projection positions of the first trigger post 21 and the second trigger post 22 on the first set line are both spaced from the position where the rigid support member 23 is located.

[0035] In this embodiment, the first button board 2 placed in the groove 1121 may be a symmetric structure. The first set line may be its axis of symmetry. A rigid support member 23 is provided at one end of the first button board 2 along the axis of symmetry, for example, the rear end, and is ball-hinged to the bottom wall of the groove 1121 through the rigid support member 23. The axis of symmetry of the first button board 2 can divide the first button board 2 into a left half and a right half. The first trigger post 21 may be provided at the left half of the first button board 2, and the second trigger post 22 may be provided at the right half of the first button board 2. Moreover, the projection positions of the first trigger post 21 and the second trigger post 22 on the axis of symmetry are respectively spaced from the position where the rigid support member 23 is located. That is to say, the first trigger post 21 is located in front of and to the left of the rigid support member 23, and the second trigger post 22 is located in front of and to the right of the rigid support member 23.

[0036] In this way, when pressed at the left front part of the first button board 2 and rotated relative to the rigid support member 23, the downward movement stroke of the first trigger post 21 in front of and to the left of the rigid support member 23 can be more than the downward movement stroke of the second trigger post 22 in front of and to the right of the rigid support member 23. Therefore, at this time, when the first trigger post 21 descends to a preset stroke and triggers the corresponding micro switch 121, the second trigger post 22 will not trigger the corresponding micro switch 121. Similarly, when pressed at the right front part of the first button board 2 and rotated relative to the rigid support member 23, the downward movement stroke of the second trigger post 22 in front of and to the right of the rigid support member 23 can be more than the downward movement stroke of the first trigger post 21 in front of and to the left of the rigid support member 23. Therefore, at this time, when the second trigger post 22 descends to a preset stroke and triggers the corresponding micro switch 121, the first trigger post 21 will not trigger the corresponding micro switch 121, thereby realizing that the first trigger post 21 and the second trigger post 22 will not trigger the corresponding micro switches 121 simultaneously.

[0037] Moreover, the rigid support member 23 used as the rotation fulcrum is designed at the rear end of the first key plate 2 along the symmetry axis, very close to the rear edge. That is, the lever arm from the rear edge to the fulcrum (rigid support member 23) is very short. Therefore, when the left front part of the first key plate 2 is pressed, even though the right rear part symmetric to the left front part with respect to the fulcrum will be lifted, due to its very short lever arm, there will basically be no obvious lifting. Similarly, when the right front part of the first key plate 2 is pressed, there will basically be no obvious lifting of the left rear part of the fulcrum. Therefore, there will be no obvious lifting at the edge of the entire first key plate 2, and the degree of lifting can even be ignored, ensuring a high consistency between the edge of the first key plate 2 and the main body part 1. Further, compared with the prior art where the rotation fulcrum is designed in the middle of the key plate, the edge of the first key plate 2 of the present utility model does not need to have a large gap with the side wall of the surrounding groove 1121 when not pressed, so external impurities are not easily introduced, and the overall shape is more beautiful, and the consistency and matching of the first key plate 2 and the main body part 1 are better.

[0038] In other embodiments, the first key plate 2 may not be a symmetric structure. At this time, the first setting line may be the setting line in any direction of the first key plate 2. For example, if the first key plate 2 is in the shape of a right trapezoid, the first setting line may be the vertical connection line between the midpoints of the top side and the bottom side of the right trapezoid; or for another example, if the first key plate 2 is in the shape of a parallelogram, the first setting line may be the connection line between the midpoints of two parallel sides of the parallelogram. In other embodiments, even when the first key plate 2 is a symmetric structure, the first setting line may not be the symmetry axis of the first key plate 2. For example, if the first key plate 2 is in the shape of an isosceles trapezoid, the first setting line may be the connection line between the midpoints of the two waists of the isosceles trapezoid.

[0039] For the convenience of description, hereinafter, it is taken as an example that the first key plate 2 is a symmetric structure, and the first setting line appearing hereinafter is the symmetry axis (parallel to the X-axis direction) of the first key plate 2.

[0040] In this embodiment, when the first key plate 2 is no longer pressed, the first key plate 2 can be lifted by the micro switch 121 that can be reset and reset to the horizontal state.

[0041] In this embodiment, the rigid support member 23, the first trigger post 21, and the second trigger post 22 can be an integrally formed structure with the first key plate 2, and no additional connection structure needs to be provided, and the overall structural strength is relatively high.

[0042] Optionally, see Figure 1 or Figure 5, on one side (or the outer side) of the first key plate 2 facing away from the bottom wall of the groove 1121, a first key mark 27 and a second key mark 28 are provided. Among them, the first key mark 27 is correspondingly arranged with the first trigger post 21 on the inner side of the first key plate 2, and the second key mark 28 is correspondingly arranged with the second trigger post 22 on the inner side of the first key plate 2. In this way, it can remind the user to press at the corresponding key mark position so that the corresponding trigger post on the inner side triggers the corresponding micro switch 121 downward.

[0043] Optionally, referring to Figure 5 , an elastic support structure 7 is provided between the main body portion 1 and the first key plate 2. The elastic support structure 7 is located on the first set line, and the elastic support structure 7 and the rigid support member 23 are arranged at intervals along the first set line.

[0044] In this embodiment, in addition to rigidly supporting the first key plate 2 through the rigid support member 23 at the rear end, an elastic support structure 7 is also provided between the main body portion 1 and the first key plate 2 to flexibly support the first key plate 2, and the elastic support structure 7 for flexible support is also located on the first set line, so as to isolate the two parts (the left front part and the right front part) where the first trigger post 21 and the second trigger post 22 are located. In this way, on the one hand, whether the left front part of the first key plate 2 is pressed or the right front part of the first key plate 2 is pressed, when released, the elastic support structure 7 at the first set line can play a role in lifting the first key plate 2 so that the first key plate 2 is reset to the horizontal state; on this basis, the reset of the first key plate 2 can no longer rely on the reset of the micro switch 121, and through the design of the material of the elastic support structure 7, after the elastic support structure 7 contracts, its elastic force is greater than the elastic force after the micro switch 121 contracts; on the other hand, through the isolation effect of the elastic support structure 7, it can further prevent the first trigger post 21 and the second trigger post 22 from being pressed simultaneously.

[0045] In addition, when the first key plate 2 is pressed to trigger the corresponding micro switch 121, the presence of the elastic support structure 7 can provide a certain touch feeling for the user. That is, when the user presses the left front part of the first key plate 2 to make the first trigger post 21 trigger the corresponding micro switch 121, a certain pressing force (this force is denoted as the first pressing force) is required to overcome the elastic force of the elastic support structure 7 to trigger the corresponding micro switch 121; when the user presses the right front part of the first key plate 2 to make the second trigger post 22 trigger the corresponding micro switch 121, a certain pressing force (this force is denoted as the second pressing force) is also required to trigger the corresponding micro switch 121. After the first pressing force and the second pressing force are fed back to the user's finger, a certain touch feeling is given to the user so as to facilitate the user to sense whether the pressing is in place.

[0046] In this embodiment, as described above, through the isolation of the elastic support structure 7, it is possible to further prevent the first trigger post 21 and the second trigger post 22 from being pressed simultaneously. Specifically, the existence of the elastic support structure 7 can ensure that the first key plate does not rotate around the second set line, thereby ensuring that the first trigger post 21 and the second trigger post 22 do not simultaneously trigger the corresponding micro switch 121. Among them, the ball joint center of the rigid support 23 is located on the second set line, and the second set line is parallel to the transverse Y-axis direction. It can be imagined that without the elastic support structure 7, when the left part of the first key plate 2 is pressed, due to the uncertainty of the direction of the pressing force, that is, the direction of the pressing force may be directly downward or at an angle to the directly downward direction. Therefore, precisely because of this uncertainty in the direction of the pressing force, after the left part of the first key plate 2 is pressed, there is a movement situation, that is, the first key plate 2 rotates around the second set line. In this case, the first trigger post 21 on the left part of the first key plate 2 and the second trigger post on the right part will simultaneously descend a relatively large stroke and simultaneously trigger the corresponding micro switch 121. Therefore, after designing the elastic support structure 7 located on the first set line, this situation can be eliminated, that is, after the left part of the first key plate 2 is pressed, because the force application point of the first key plate 2 is on the left side of the elastic support structure 7, the left part of the first key plate 2 will be more likely to descend than the right part, rather than rotating and descending the same stroke along the second set line. In this way, the descending stroke of the first trigger post 21 on the left side of the elastic support structure 7 will be more than the descending stroke of the second trigger post 22 on the right side, thereby further preventing the first trigger post 21 and the second trigger post 22 from simultaneously triggering the corresponding micro switch 121.

[0047] In addition, if the finger directly presses on the position of the elastic support structure 7 at the midline, a greater pressing force than the first pressing force and the second pressing force is required to press the first key plate 2 at this position and rotate it around the second set line, so that the first trigger post 21 and the second trigger post 22 descend the same stroke. Therefore, if the user's finger presses at the position of the elastic support structure 7 on the first set line, the resistance received will be very large and it is difficult to press here. At this time, the user can know that this position cannot be pressed.

[0048] Optionally, referring to Figures 3 - 5 , the projected positions of the first trigger post 21 and the second trigger post 22 on the first set line are both located on the side of the elastic support structure 7 away from the rigid support 23; and / or, the first trigger post 21 and the second trigger post 22 are symmetric about the first set line.

[0049] In this embodiment, when pressing the first keypad 2 to rotate the first keypad 2 relative to the ball joint center of the rigid support member 23, the elastic force of the elastic support structure 7 needs to be overcome, and the farther the pressing point is from the ball joint center of the rigid support member 23, the less effort is required, that is, the aforementioned first pressing force and second pressing force will not be too large while providing a certain tactile feeling. Therefore, the projection position of the first trigger column 21 to the first setting line is designed to be in front of the elastic support structure 7, and the projection position of the second trigger column 22 to the first setting line is also designed to be in front of the elastic support structure 7.

[0050] In this embodiment, the first trigger column 21 and the second trigger column 22 are symmetrical about the first setting line, so that the pressing force at the first button mark 27 is the same as the pressing force at the second button mark 28, that is, the aforementioned first pressing force and the second pressing force are the same, ensuring that the pressing touch on the left and right sides is consistent.

[0051] Alternatively, see Figure 2 as well as Figures 6 - 7 The first button plate 2 is provided with a buckle 24 protruding from one side of the bottom wall of the groove 1121, and the multiple buckles 24 are respectively located on both sides of the first setting line. The bottom wall of the groove 1121 is provided with a card slot, and the buckle 24 is engaged with the card slot.

[0052] In this embodiment, in addition to the hard support member 23, the first trigger column 21 and the second trigger column 22, the lower side of the first key plate 2 is also provided with a plurality of buckles 24 protruding therefrom. The plurality of buckles 24 are respectively located on the left and right sides of the first setting line. Figure 4 As shown, for example, three buckles 24 are provided on the left side of the first setting line, and three buckles 24 are also provided on the right side of the first setting line. After the buckles 24 are engaged with the slots of the bottom wall of the groove 1121, on the one hand, it is ensured that the first key panel 2 is connected to the bottom wall of the groove 1121 and will not fall off; on the other hand, it can allow the first key panel 2 to be slightly displaced relative to the main body 1, that is, it allows a part of the first key panel 2 to be pressed, and at the same time, it can prevent the first key panel 2 from rotating around the X-axis direction when being pressed. For example, when the left front part of the first key panel 2 is pressed, the right part of the first key panel 2 will not be lifted up as a whole under the engagement limit of the buckles 24 and the slots.

[0053] Alternatively, see 2-4 and Figure 7The main body 1 has a hollow cavity, the slot 1123 extends from the bottom wall of the groove 1121 to the hollow cavity, and the slot wall of the slot 1123 is protruding with the limiting protrusion 1124; the buckle 24 is a hook-shaped structure, which includes an arm 241 and a hook 242 arranged at the end of the arm 241, and the hook 242 extends into the slot 1123 and abuts against a side of the limiting protrusion 1124 away from the first key plate 2.

[0054] As mentioned above, the connection between the buckle 24 and the slot can prevent the first key panel 2 from rotating around the X-axis. Specifically, when the first key panel 2 is in the initial state, that is, in the horizontal state, the upper side wall of the hook portion 242 in the buckle 24 is in surface contact with the lower side wall of the limiting protrusion 1124, and when the first key panel 2 is pressed at the first key mark 27 on the left side of the first setting line, the right part of the first key panel 2 will not rotate and tilt around the X-axis because the right buckle 24 hooks the limiting protrusion 1124, ensuring that the left and right sides of the first key panel 2 will basically not tilt.

[0055] It should be noted that the buckle 24 hooks the limiting protrusion 1124 , which means that the hook portion 242 of the buckle 24 abuts against the bottom wall of the limiting protrusion 1124 , which can ensure that the first key plate 2 will not rotate around the X-axis direction. It is conceivable that if the buckle 24 is not designed to hook the limiting protrusion 1124, when the left part of the first key panel 2 is pressed, there is uncertainty in the direction of the pressing force, that is, the direction of the pressing force may be directly downward, or it may be a direction at a certain angle to the direction directly downward. Therefore, due to the uncertainty of the direction of the pressing force, after the left part of the first key panel 2 is pressed, there is a movement situation, that is, the first key panel 2 rotates around the X-axis direction. In this case, the edge of the right part of the first key panel 2 will almost be lifted, and the lifting distance will be larger; therefore, after the buckle 24 is designed to hook the limiting protrusion 1124, the limiting protrusion 1124 can block the hook 242 of the buckle from moving upward, thereby eliminating this situation (eliminating the movement of the first key panel 2 rotating around the X-axis direction), ensuring that even if there is a lifting situation, it only exists at the rear end of the first key panel 2 close to the position of the hard support member 23, and the degree of lifting is minimal.

[0056] In this embodiment, the card slot 1123 is a slot structure that penetrates through to the hollow cavity, and a limiting bump 1124 is protrudingly provided on the inner wall of the card slot 1123. The snap-fit connection between the snap 24 and the card slot 1123 specifically refers to that the hook portion 242 of the snap 24 abuts against the lower side wall of the limiting bump 1124. In this way, at least part of the arm portion 24 of the snap and the hook portion 242 are located within the card slot 1123, which can improve the integration degree of the remote control key in the Z-axis direction, and at the same time will not additionally occupy the space inside the hollow cavity, nor interfere with the parts inside the hollow cavity.

[0057] Wherein, the main body portion 1 can be the key housing 11. A groove 1121 is recessed on one side surface (such as the upper side surface) of the key housing 11, and the key housing 11 has a hollow cavity inside.

[0058] Optionally, referring to Figures 2 - 3 and Figure 6 , a spherical groove 1122 is provided on the bottom wall of the groove 1121, and the end portion of the rigid support member 23 is supported in the spherical groove 1122, and the shape of the end portion of the rigid support member 23 matches the shape of the spherical groove 1122.

[0059] In this embodiment, by providing the spherical groove 1122 on the bottom wall of the groove 1121, the bottom end of the rigid support member 23 is rotationally fitted in the spherical groove 1122 to achieve a ball joint connection. The center of the sphere of the spherical groove 1122 is located outside the spherical groove 1122. In this way, the bottom end of the rigid support member 23 can be directly placed in the spherical groove 1122, and the installation is convenient.

[0060] Optionally, referring to Figures 2 - 4 , the remote control key further includes a separator 3. A notch groove 25 is provided along the first set line at one end of the first button board 2 away from the rigid support member 23. The connection line between the first trigger post 21 and the second trigger post 22 intersects the notch groove 25. At least part of the separator 3 is located in the notch groove 25, and the separator 3 is connected to the main body portion 1.

[0061] In this embodiment, since the connection line between the first trigger post 21 and the second trigger post 22 intersects the notch groove 25, the first trigger post 21 and the second trigger post 22 are respectively located on the left and right sides of the notch groove 25. Similarly, the first button identifier 27 and the second button identifier 28 are also respectively located on the left and right sides of the notch groove 25. And since at least a part of the separator 3 is located in the notch groove 25, the first button identifier 27 and the second button identifier 28 are also respectively located on the left and right sides of the separator 3 in the notch groove 25. If the user accidentally presses the middle position between the first button identifier 27 and the second button identifier 28, it will be blocked by the separator 3 in the notch groove 25, and the first button plate 2 will not be pressed down, avoiding the situation where the first trigger post 21 and the second trigger post 22 simultaneously trigger the corresponding micro switch 121.

[0062] It can be understood that when the first button plate 2 is in a horizontal state, the top end of the separator 3 is flush with or higher than the first button plate 2. The separator 3 can be specifically connected and fixed to the bottom wall of the groove 1121.

[0063] It can be understood that the separator 3 is arranged with a gap from the side wall of the notch groove 25, so that the first button plate 2 can move up and down relative to the separator 3 to ensure that the first button plate 2 is not interfered by the separator 3 during movement.

[0064] Optionally, referring to Figures 6 - 7 , the main body portion 1 includes a circuit board 12, the circuit board 12 is located in the hollow cavity of the main body portion 1, that is, the circuit board 12 is located in the key housing 11.

The stud 26 and the elastic protrusion 131 constitute the aforementioned elastic support structure 7, and the elastic protrusion 131 provides the elastic force when the first key board 2 is pressed. The elastic protrusion 131 can be made of silicone material and has the ability of elastic deformation.

[0068] Among them, the gasket 13 has the ability of elastic deformation and can be made of silicone material. The edge of the gasket 13 is disposed between the first cover 111 and the second cover 112, which can play a role in sealing the key housing 11; the elastic protrusion 131 is a protrusion structure disposed on the gasket. A hollow protrusion cap 132 may be further protrudingly provided on the side of the gasket 13 facing the first key board 2. Each of the plurality of micro switches 121 extends into the corresponding protrusion cap 132. When the first trigger post 21 or the second trigger post 22 is pressed, it can pass through the corresponding through hole 1125 and trigger the corresponding micro switch 121 by deforming downward through the protrusion cap 132.

[0069] Optionally, referring to Figures 1 - 3 and Figures 5 - 6 , the remote control key further includes a second key board 4 independently disposed from the first key board 2.

The spacer ring 6 is located between the second key board 4 and the hole wall of the board hole, and the spacer ring 6 is connected to the bottom wall of the groove 1121. By arranging the second key board 4 in the area where the first key board does not need to be pressed (the position of the first key board 2 at the first set line, that is, the middle position of the first key board 2), the integration degree is relatively high.

[0070] Among them, in the direction of the first set line, the board hole is located between the rigid support member 23 and the elastic support structure 7, the elastic support structure 7 is located between the board hole and the notch groove 25, the bottom end of the partition ring 6 is fixed to the bottom wall of the groove 1121, a third trigger post may be provided on the lower side of the second button board 4. After the second button board 4 is pressed, it can move vertically downward and trigger the corresponding micro switch 121. A third button identifier 41 corresponding to the third trigger post may be provided on the upper side of the second button board 4. Among them, the partition ring 6 can ensure that the first button board 2 and the second button board 4 are not pressed simultaneously. It can be understood that there is a gap between the inner wall of the board hole and the outer peripheral wall of the partition ring 6 to ensure that the movement of the first button board 2 is not interfered by the partition ring 6.

[0071] Optionally, referring to Figures 1 - 3 and Figures 5 - 6 , the remote control key further includes a third button board 5. The front end of the first button board 2 includes two set sides arranged at an angle (that is, the two front sides shown in the figure).
