Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switches, in particular to a multi-position key switch. Background Art
[0002] The existing multi-position key switch includes a mounting base and at least two key plates spaced apart on the mounting base. In order to prevent two adjacent key plates in the multi-position switch from rubbing against each other during movement, resulting in an unsmooth feel of the key plates or even failure of the key plates, a certain isolation gap is provided between the two adjacent key plates. Since the components used to fix the limit key plates inside the multi-position switch have installation gaps and error accumulation, the isolation gap between some adjacent key plates presents a trumpet shape in which the gap gradually increases from the bottom to the top, which affects the overall appearance of the multi-position key switch. Utility Model Content
[0003] In order to overcome the disadvantage that the isolation gap between two adjacent key plates of the multi-position key switch in the prior art is in a trumpet shape, which affects the overall appearance of the switch, the utility model provides a multi-position key switch, which makes the isolation gap between the adjacent key plates look more uniform in appearance, and can make the overall appearance of the multi-position key switch more beautiful.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-position key switch, comprising a mounting base and at least two key plates spaced apart on the mounting base, an isolation gap being provided between two adjacent key plates, a separator being provided in the isolation gap, and a gap being provided between the separator and the two adjacent key plates.
[0005] In the above technical solution, the isolation gap is divided into smaller gaps by a separator, and the spacing of the smaller gaps is smaller. It is more difficult for the user to distinguish that the isolation gap is in the shape of a trumpet with naked eyes. In terms of appearance, the isolation gaps between adjacent key panels look more uniform, which can make the overall appearance of the multi-position key switch more beautiful; and the overall appearance of the multi-position key switch can be made more beautiful without changing other structures of the multi-position key switch. Since the application of the utility model can be completed by directly adding a separator to the existing multi-position key switch, it is very easy to implement, the feasibility is very high, and the modification cost can also be reduced. At the same time, the separator also has a protective effect, which can prevent some debris from falling into the isolation gap and affecting the pressing of the key panel.
[0006] The utility model is further configured such that the gap width between the separator and the adjacent key panel ranges from 0.2 mm to 0.3 mm.
[0007] In the above technical solution, the gap width between the separator and the adjacent keypad is in the range of 0.2mm~0.3mm, which can reduce the risk of interference between the separator and the keypad while ensuring the aesthetic effect. If the gap width between the separator and the adjacent keypad is greater than 0.3mm, the gap width formed by the separator separating the isolation gap is not small enough, and the user can easily distinguish that the isolation gap is in the shape of a trumpet, which affects the beautification effect of the separator; if the gap width between the separator and the adjacent keypad is less than 0.2mm, the gap width formed by the separator separating the isolation gap is too small. Since there are installation gaps and error accumulations in the components used to fix the limit keypad inside the multi-position switch, it is easy to cause the two adjacent keypads to rub against each other during movement, resulting in an unsmooth feel of the keypad or even failure of the keypad.
[0008] The utility model is further configured as follows: the key panel includes a trigger state and a non-trigger state, the middle portion of the upper end of the separator is inclined toward opposite sides to form a first surface and a second surface, when the key panel is in the trigger state, the first surface is parallel to the touch surface of the key panel, and when the key panel is in the non-trigger state, the second surface is parallel to the touch surface of the key panel.
[0009] In the above technical solution, the first surface is parallel to the touch surface of the keypad in the triggered state, and the second surface is parallel to the touch surface of the keypad in the non-triggered state, which can make the surface of the multi-position key switch look smoother and is beneficial to the beauty of the multi-position key switch.
[0010] The utility model is further configured such that: when the keypad is in a triggered state, the first surface is lower than or flush with the touch surface of the keypad; when the keypad is in a non-triggered state, the second surface is lower than or flush with the touch surface of the keypad.
[0011] In the above technical solution, when the keypad is in a triggered state, the first surface is lower than or flush with the touch surface of the keypad, and when the keypad is in a non-triggered state, the second surface is lower than or flush with the touch surface of the keypad, so that the separator does not protrude from the keypad, and the surface of the multi-position key switch can be smoother, which is beneficial to the appearance of the multi-position key switch; at the same time, it is not easy for the user to touch the separator when pressing the keypad, reducing the influence of the separator on the user's pressing feel.
[0012] The utility model is further configured as follows: a plurality of separators are sequentially arranged in the isolation gap along the length direction of the isolation gap, and the width of each separator is adapted to the width of the isolation gap in the section where it is located, so that the gap width between each separator and the adjacent key plate is equal.
[0013] In the above technical solution, the width of each separator is adapted to the width of the isolation gap of the segment where it is located, so that the gap width between each separator and the adjacent key plate is equal, which makes the isolation gap between adjacent key plates look more uniform in appearance, and can make the overall appearance of the multi-position key switch more beautiful. The segment refers to the position of the separator corresponding to the isolation gap.
[0014] The utility model is further configured as follows: a first limiting member is provided on the mounting base, and a second limiting member is provided on the partition, and the first limiting member cooperates with the second limiting member to limit the partition in the width direction of the isolation gap and to vertically fix the partition relative to the mounting base.
[0015] In the above technical solution, the separator is limited in the width direction of the isolation gap by the cooperation of the first limit member and the second limit member, which can prevent the separator from shaking in the width direction of the isolation gap, causing the separator to tilt in the width direction of the isolation gap and affecting the appearance of the multi-position key switch, or the separator is skewed and interferes with the key panel, affecting the pressing of the key panel.
[0016] The utility model is further configured as follows: the first limiting member is at least two waist-shaped holes spaced apart along the length direction of the isolation gap, the length direction of the waist-shaped holes is parallel to the length direction of the isolation gap, the second limiting member is a positioning column corresponding to the waist-shaped hole and extending toward the mounting base, the positioning column is plugged into the waist-shaped hole, and the positioning column and the positioning hole are tightly matched in the width direction of the isolation gap.
[0017] In the above technical solution, the positioning column is inserted into the waist-shaped hole to realize the positioning of the separator in the width direction of the isolation gap. The positioning column and the positioning hole are tightly matched in the width direction of the isolation gap, which can prevent the separator from shaking in the width direction of the isolation gap, causing the separator to tilt in the width direction of the isolation gap, affecting the appearance of the multi-position key switch, or the separator deflection interferes with the key board and affects the pressing of the key board. At the same time, it can also help the waist-shaped hole to redundantly accommodate the error of the positioning column in the length direction of the isolation gap, which can reduce the manufacturing accuracy of the separator and thus reduce the manufacturing cost.
[0018] The utility model is further configured as follows: the separator is provided with a first limiting surface facing the mounting base, the mounting base is provided with a first supporting surface, and the first limiting surface abuts against the first supporting surface.
[0019] In the above technical solution, the separator is positioned by abutting the first limiting surface against the first supporting surface, which facilitates the installation of the separator.
[0020] The utility model is further configured as follows: a second limiting surface perpendicular to the first limiting surface is provided on the separator, the second limiting surface is perpendicular to the length direction of the isolation gap, a second supporting surface is provided on the mounting base, and the second limiting surface abuts against the second supporting surface.
[0021] In the above technical solution, the partition is positioned by abutting the second limiting surface against the second supporting surface, which facilitates the installation of the partition.
[0022] The utility model is further configured as follows: a groove is provided on the upper surface of the partition member facing the mounting base, a convex rib is provided on the mounting base, and the groove is clamped with the convex rib; and / or a guiding concave surface extending obliquely from the inside to the outside is provided on the lower surface of the middle part of the partition member, and a receiving convex surface adapted to the guiding concave surface is provided on the mounting base, and the guiding concave surface is tightly attached to the receiving convex surface.
[0023] The beneficial effect of the utility model is that the isolation gap is divided into two parts in the width direction of the isolation gap by the separator to form two smaller gaps, the spacing between the smaller gaps is smaller, and it is more difficult for the user's naked eye to distinguish that the first gap is trumpet-shaped. In appearance, the isolation gaps between adjacent key panels look more uniform, and the overall appearance of the multi-position key switch can be made more beautiful.

DETAILED DESCRIPTION
[0032] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0033] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0034] like Figures 1 to 7 As shown, a multi-position key switch includes a mounting base 1 and at least two key plates 2 spaced apart on the mounting base 1, an isolation gap 21 is provided between two adjacent key plates 2, a separator 3 is provided in the isolation gap 21, and there is a gap between the separator 3 and the two adjacent key plates 2.
[0035] In this embodiment, the isolation gap 21 is divided into smaller gaps by the separator 3, and the spacing of the smaller gaps is smaller. It is more difficult for the user to distinguish that the isolation gap 21 is in the shape of a trumpet with the naked eye. In terms of appearance, the isolation gaps 21 between adjacent key panels 2 look more uniform, which can make the overall appearance of the multi-position key switch more beautiful; and the overall appearance of the multi-position key switch can be made more beautiful without changing other structures of the multi-position key switch. Since the application of the utility model can be completed by directly adding the separator 3 to the existing multi-position key switch, it is very easy to implement, the feasibility is very high, and the modification cost can also be reduced. At the same time, the separator 3 also has a protective effect, which can prevent some debris from falling into the isolation gap 21 and affecting the pressing of the key panel 2.
[0036] Specifically, the key plate 3 is installed on the installation base 1 .
[0037] Specifically, the gap width between the separator 3 and the adjacent key panel 2 ranges from 0.2mm to 0.3mm. This can reduce the risk of interference between the separator 3 and the key panel 2 while ensuring the aesthetic effect. If the gap width between the separator 3 and the adjacent key panel 2 is greater than 0.3mm, the gap width formed by the separator 3 separating the isolation gap 21 is not small enough, and the user can easily distinguish that the isolation gap 21 is in the shape of a trumpet, which affects the beautification effect of the separator 3; if the gap width between the separator 3 and the adjacent key panel 2 is less than 0.2mm, the gap width formed by the separator 3 separating the isolation gap 21 is too small. Since there are installation gaps and error accumulations in the components used to fix the limit key panel 2 inside the multi-position switch, it is easy to cause the two adjacent key panels 2 to rub against each other during movement, resulting in an unsmooth feel of the key panel 2 or even failure of the key panel 2.
[0038] Specifically, in the present embodiment, the gap width between the separator 3 and the adjacent key plate 2 is 0.25 mm. Of course, in other embodiments, the gap width between the separator 3 and the adjacent key plate 2 may also be 0.2 mm, 0.3 mm or other suitable widths.
[0039] Specifically, Figure 1 and Figure 4 As shown, the keypad 2 includes a trigger state and a non-trigger state, and the middle of the upper end of the separator 3 is inclined to opposite sides to form a first surface 36 and a second surface 37. When the keypad is in the trigger state, the first surface 36 is parallel to the touch surface of the keypad 2, and when the keypad 2 is in the non-trigger state, the second surface 37 is parallel to the touch surface of the keypad. The surface of the multi-position key switch can be made flatter, which is beneficial to the beauty of the multi-position key switch. It should be noted that the upper end of the separator 3 is the end away from the mounting base 1.
[0040] Specifically, if Figure 4 As shown, in this embodiment, the first surface 36 and the second surface 37 form a certain angle, and the key panel 2 adjusts the trigger state and the non-trigger state by rotating on the mounting base 1. The key panel 2 forms a certain angle with the mounting base 1 in the trigger state and the non-trigger state, and the angle between the first surface 36 and the second surface 37 is equal to twice the angle between the key panel 2 and the mounting base 1.
[0041] Specifically, when the keypad 2 is in a triggered state, the first surface 36 is lower than the touch surface of the keypad 2, and when the keypad 2 is in a non-triggered state, the second surface 37 is lower than the touch surface of the keypad 2. By making the separator 3 not protrude from the keypad 2, the surface of the multi-position key switch can be smoother, which is beneficial to the aesthetics of the multi-position key switch; at the same time, it is not easy for the user to touch the separator 3 when pressing the keypad 2, reducing the influence of the separator 3 on the user's pressing feel. It can be understood that in other embodiments, when the keypad 2 is in a triggered state, the first surface 36 is flush with the touch surface of the keypad 2, and when the keypad 2 is in a non-triggered state, the second surface 37 is flush with the touch surface of the keypad 2. It should be noted that the touch surface of the keypad 2 is the surface that is contacted when the user presses the keypad.
[0042] Specifically, a first limiting member is provided on the mounting base, and a second limiting member is provided on the partition, and the first limiting member cooperates with the second limiting member to limit the partition in the width direction of the isolation gap, and the partition is fixed vertically relative to the mounting base. By cooperating with the first limiting member and the second limiting member, the partition is limited in the width direction of the isolation gap, which can prevent the partition from shaking in the width direction of the isolation gap, causing the partition to tilt in the width direction of the isolation gap, affecting the appearance of the multi-position key switch, or the separator is deflected and interferes with the key board, affecting the pressing of the key board.
[0043] Among them, Figures 3 to 7 As shown, the first limiting member is provided with at least two waist-shaped holes 11 at intervals along the length direction of the isolation gap 21, and the length direction of the waist-shaped holes 11 is parallel to the length direction of the isolation gap 21. The second limiting member is a positioning column 31 corresponding to the waist-shaped hole 11 and extending toward the mounting base 1. The positioning column 31 is inserted into the waist-shaped hole 11, and the positioning column 31 and the positioning hole are tightly matched in the width direction of the isolation gap 21. The positioning column 31 is inserted into the waist-shaped hole 11 to realize the installation and positioning of the separator 3 in the width direction of the isolation gap 21. The positioning column 31 and the positioning hole are tightly matched in the width direction of the isolation gap 21, which can prevent the separator 3 from shaking in the width direction of the isolation gap 21, causing the separator 3 to tilt in the width direction of the isolation gap 21, affecting the appearance of the multi-position key switch, or the separator 3 is deflected and interferes with the key board 2 to affect the pressing of the key board 2. At the same time, it can also help the waist-shaped hole 11 to redundantly accommodate the error of the positioning column 31 in the length direction of the isolation gap 21, which can reduce the manufacturing accuracy of the separator 3, thereby reducing the manufacturing cost. The positioning column 31 extends toward the mounting base 1 to vertically fix the partition relative to the mounting base.
[0044] It is understandable that in other embodiments, the first limit member and the second limit member have other structural forms. For example, in another embodiment, the first limit member is a slot, and the second limit member is a corresponding buckle. The partition is vertically fixed relative to the mounting base through the cooperation of the buckle and the slot, and the partition is limited in the width direction of the isolation gap.
[0045] In addition, the length direction of the isolation gap 21 is as follows Figure 1 In the X direction shown in FIG. 1 , the width direction of the isolation gap 21 is as follows: Figure 1 Y direction shown.
[0046] Specifically, Figures 3 to 7 As shown, the separator 3 is provided with a first limiting surface 32 facing the mounting base 1, the mounting base 1 is provided with a first supporting surface 12, and the first limiting surface 32 abuts against the first supporting surface 12. By abutting the first limiting surface 32 against the first supporting surface 12, the separator 3 is positioned to facilitate the installation of the separator 3.
[0047] Specifically, Figures 3 to 7 As shown, the separator 3 is provided with a second limiting surface 33 perpendicular to the first limiting surface 32, the second limiting surface 33 is perpendicular to the length direction of the isolation gap 21, and the mounting base 1 is provided with a second supporting surface 13, and the second limiting surface 33 abuts against the second supporting surface 13. The separator 3 is positioned by abutting the second limiting surface 33 against the second supporting surface 13, which facilitates the installation of the separator 3.
[0048] Specifically, Figure 3 , Figure 4 and Figure 7 As shown, a groove 34 is provided on the separator 3 facing the mounting base 1 , and a convex rib 14 is provided on the mounting base 1 , and the groove 34 is engaged with the convex rib 14 .
[0049] Specifically, Figure 3 , Figure 4 and Figure 7 As shown, the lower surface of the middle part of the partition 3 is provided with a guide concave surface 35 extending obliquely from the inside to the outside, and the mounting base 1 is provided with a receiving convex surface 15 adapted to the guide concave surface 35, and the guide concave surface 35 is closely attached to the receiving convex surface 15. The guide concave surface 35 and the receiving convex surface 15 form an assembly guide, which facilitates the installation of the partition 3.
[0050] Specifically, a plurality of separators 3 are sequentially arranged in the isolation gap 21 along the length direction of the isolation gap 21, and the width of each separator 3 is adapted to the width of the isolation gap 21 of the section where it is located, so that the gap width between each separator and the adjacent key plate is equal. The width of each separator 3 is adapted to the width of the isolation gap 21 of the section where it is located, so that the isolation gaps 21 between adjacent key plates 2 look more uniform in appearance, and the overall appearance of the multi-position key switch can be made more beautiful.
[0051] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
