However, if other words can achieve the same purpose, the words can be replaced by other expressions.
[0017] As shown in this specification and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0018] Figure 1 is an exemplary exploded diagram of a key structure according to some embodiments of the present specification. Figure 2 An exemplary schematic diagram of the key structure shown in some embodiments of the present specification.
[0019] This specification provides a key structure 10, such as Figure 1 and Figure 2 As shown, the button structure 10 may include a panel 11 , a button 12 , a button bracket 13 , a connecting component 14 and a switch module 15 .
[0020] The panel 11 is an upper cover of the key structure 10 and can be used as an installation base to assemble the key structure 10 .
[0021] like Figure 1 As shown, the panel 11 may be provided with a key through hole 111. The key through hole 111 allows the key 12 to be assembled into the panel 11. The size and shape of the key through hole 111 are adapted to the key 12.
[0022] The button 12 is a device that enables the user to operate the power switch by pressing. The button 12 can be circular, rectangular or any other shape. Figure 2 As shown, the button 12 is disposed through the button through hole 111 of the panel 11. The user can drive the movement of the connecting component 14 by pressing the button 12.
[0023] The connection component 14 is a component used to connect the button 12 and the switch module 15. In some embodiments, the connection component 14 may include a connection rod 141 and a spring 142. For more details, please refer to the relevant description below.
[0024] like Figure 2 As shown, the end of the connecting component 14 close to the button 12 is connected to the bottom of the button 12, and the end away from the button 12 is in contact with the switch module 15. The bottom of the button 12 refers to the side of the button 12 close to the switch module 15. The connecting component 14 and the button 12 can be fixedly connected by snapping, bonding or any other feasible method. In some embodiments, the connecting component 14 can pass through the through hole 131 of the button bracket 13 and be fixedly connected to the button 12.
[0025] The button bracket 13 is a component for supporting and fixing the button 12. In some embodiments, the button bracket 13 is provided with a through hole 131, and the shape of the through hole 131 is adapted to the shape of the connecting component 14. The area of the cross section of the through hole 131 along the axis perpendicular to the connecting component 14 is slightly larger than the area of the cross section of the connecting component 14 along the axis perpendicular to the connecting component 14, so that the connecting component 14 can pass through the through hole 131. The size of the through hole 131 can be determined according to actual conditions. By controlling the size of the through hole 131, the shaking amount of the connecting component 14 can be further reduced.
[0026] In some embodiments, the key bracket 13 can be fixedly connected to the panel 11. For example, the key bracket 13 can be fixedly connected to the panel 11 by screws 132 and spacer columns 133. Figure 1 As shown, there are threaded holes at the matching positions of the key bracket 13 and the panel 11, and the screws 132 pass through the threaded holes in the key bracket 13 and are threadedly connected to the spacer 133, and the spacer 133 is threadedly connected to the corresponding threaded holes in the panel 11. There can be two threaded holes in the key bracket 13 and the panel 11, and they are arranged along the diagonal line in the key bracket 13 and the panel 11. The key bracket 13 and the panel 11 can also be fixedly connected in other feasible ways.
[0027] The switch module 15 is a module for connecting or disconnecting a circuit. The switch module 15 may include a PCB board and potentiometer components, etc. By pressing the button 12, the user can drive the connecting component 14 to press the switch module 15, thereby connecting or disconnecting the circuit to achieve control of the power switch.
[0028] In some embodiments of the present specification, by connecting the switch module 15 and the button 12 through the connecting component 14, the direct assembly relationship between the button 12 and the switch module 15 can be changed to a controllable indirect assembly relationship, thereby effectively reducing the button shaking and eccentricity caused by the large shaking of the switch module 15 itself; by controlling the opening size of the through hole 131, the shaking amount of the button 12 can be further controlled, so that the shaking of the button 12 can be changed from uncontrollable to controllable, thereby effectively reducing the shaking of the button 12 and effectively increasing production efficiency.
[0029] like Figure 1 As shown, the connecting assembly 14 may include a connecting rod 141 and a spring 142 .
[0030] The connecting rod 141 is the main body of the connecting assembly 14 and can be used to contact the switch module 15 and the button 12. In some embodiments, the spring 142 is sleeved outside the connecting rod 141.
[0031] In some embodiments of the present specification, the spring 142 is sleeved outside the connecting rod 141 so that the connecting rod 141 can rebound, thereby ensuring the user's hand feeling when pressing the button 12 .
[0032] like Figure 1 and Figure 2 As shown, a contact 143 is provided at one end of the connecting rod 141 close to the switch module 15. The contact 143 is a component for contacting the switch module 15. The contact 143 may be a disc or other shapes. In some embodiments, the area of the cross section of the contact 143 along the axis perpendicular to the connecting rod 141 is larger than the area of the cross section of the end of the switch module 15 close to the connecting assembly 14 along the axis perpendicular to the connecting rod 141, and the area of the cross section of the contact 143 along the axis perpendicular to the connecting rod 141 is larger than the area of the cross section of the connecting rod 141 along the axis perpendicular to the connecting rod 141, and the spring 142 may be located between the contact 143 and the key bracket 13. The two ends of the spring 142 abut against the key bracket 13 and the contact 143 respectively, so as to provide a rebound force after the key 12 drives the connecting rod 141 to be pressed, and the connecting rod 141 can drive the key 12 to return to the set initial position under the action of the rebound force when it is not subjected to the pressing force.
[0033] In some embodiments of the present specification, the contact piece 143 can be used to expand the contact area between the connecting component 14 and the switch module 15, thereby providing room for adjustment during assembly, thereby reducing the assembly requirements for the button structure 10. The spring 142 is arranged between the contact piece 143 and the button bracket 13, which can limit the rebound amount of the connecting rod 141 and enhance the user's pressing feel.
[0034] like Figure 1 and Figure 2 As shown, a truncated cone portion 134 extends from one side of the button bracket 13 close to the switch module 15. The truncated cone portion may be in the shape of a truncated cone, and the diameter of the truncated cone portion 134 gradually decreases in the direction close to the switch module 15, and the through hole 131 may penetrate the truncated cone portion 134. The distance between one end of the truncated cone portion 134 close to the contact member 143 and the contact member 143 is the maximum pressing amount of the button 12. When the truncated cone portion 134 contacts the contact member 143, the user cannot continue to press the button 12 downward, that is, the button 12 reaches the maximum moving distance. The size of the truncated cone portion 134 along the axis direction of the connecting rod 14 can be preset according to actual conditions.
[0035] In some embodiments of the present specification, the truncated cone portion 134 extending from one side of the button bracket 13 close to the switch module 15 can control the amount of button pressing to ensure the user experience.
[0036] like Figure 1 As shown, a protrusion 121 extends radially from the bottom of the key 12 , and a guide portion 135 is provided on a side of the key bracket 13 close to the key 12 .
[0037] The protrusion 121 is a component of the key 12 for controlling the sliding direction of the key 12. The guide portion 135 is a component of the key bracket 13 for controlling the sliding direction of the key 12. A groove is provided inside the guide portion 135, and the shape of the groove is adapted to the protrusion 121, and the protrusion 121 is slidably located in the groove. The guide portion 135 is arranged perpendicular to the key bracket 13 to control the protrusion 121 to slide along the radial direction of the connecting rod 14.
[0038] In some embodiments of the present specification, the protrusion 121 cooperates with the groove in the guide portion 135 to ensure that the key 12 slides radially along the connecting rod 14 when pressed by the user, thereby ensuring the concentricity of the key structure 10.
[0039] like Figure 1 As shown, the number of the protrusions 121 and the guide portions 135 may be two or other feasible numbers.
[0040] The two protrusions 121 are symmetrically arranged with the axis of the through hole 131 as the symmetry axis, and the two guide portions 135 are symmetrically arranged with the axis of the through hole as the symmetry axis.
[0041] In some embodiments of the present specification, the movement direction of the button 12 can be further fixed by symmetrically arranged protrusions 121 and guide portions 135, which helps to improve the user experience and production efficiency.
[0042] In some embodiments, a first column 136 is disposed on a side of the button bracket 13 close to the button 12 .
[0043] The first pillar 136 is a columnar structure that can be used to support the panel 11. The number of the first pillars 136 can be two, and the two first pillars 136 are arranged along the diagonal line of the key bracket 13. The number of the first pillars 136 can also be other than two.
[0044] In some embodiments of the present specification, the first column 136 can improve the stability of the key bracket 13 and the panel 11, thereby improving the stability of the key structure 10.
[0045] In some embodiments, such as Figure 1 As shown, a second column 137 extends from one side of the first column 136 close to the button 12 , and a through hole 112 is provided at a position where the panel 11 and the second column 137 are adapted.
[0046] The cross-sectional area of the via 112 is smaller than that of the first column 136 , the cross-sectional area of the second column 137 is smaller than that of the via 112 , the axial length of the via 112 is greater than that of the second column 137 , and the second column 137 can be at least partially inserted into the via 112 .
[0047] In some embodiments of the present specification, by controlling the axial length of the through hole 112 , the panel 11 can be adapted to various key brackets 13 , thereby improving the assembly flexibility of the key structure 10 .
