Description

Technical Field

[0001] The utility model relates to the technical field of mechanical keys, in particular to a key device. Background Art

[0002] Indoor wire controllers in the field of home appliance central air conditioning are divided into two categories, one is touch button type, and the other is mechanical switch button type. Most of the mechanical buttons in the prior art are installed on the electronic switch through silicone. However, when the area of ​​the button is made larger, the button can be pressed and powered on except for the position close to the electronic switch. Pressing the button at other corners will have a poor effect in triggering the electronic switch. In addition, the thickness of the silicone button needs to be made very thick, which will affect the pressing feel. Utility Model Content

[0003] Based on this, it is necessary to provide a key device to solve the problem that the pressing feel and pressing effect of the current key device are poor.

[0004] The present application discloses a key device, comprising a mounting shell, the mounting shell being provided with a mounting hole; a key member, the key member being covered on the mounting shell; an elastic member and a switch assembly, the switch assembly being arranged on the mounting shell, the elastic member being arranged between the key member and the switch assembly so that the key member can move relative to the switch assembly to trigger the switch assembly; a support member, the support member being arranged on the key member, the support member being able to move relative to the mounting shell with the key member, the other end of the support member being abutted against a side wall of the mounting hole to prevent the key member from detaching from the mounting shell from the mounting hole, the key member forming a contact area that can be used to trigger the switch assembly, and the support member being located on opposite sides of the contact area.

[0005] The present application discloses a key device, wherein a key component cover is arranged at a mounting hole on a mounting shell, an elastic component and a switch assembly are arranged in the mounting shell, the elastic component is arranged between the switch assembly and the key component, and a support component is arranged on opposite sides of a contact area of ​​the key component, and can move with the movement of the key component relative to the mounting shell, so that when an edge area of ​​the key component is subjected to force, the support component close to the force-bearing side of the key component will be pressed down accordingly, and the support component away from the force-bearing side of the key component will be stopped on the mounting shell, which is equivalent to the support component away from the force-bearing side of the key component as a fixed fulcrum, so that the contact area can be equally effectively Under the downward pressure, the switch assembly can be effectively triggered by pressing in the downward direction. In this way, the single-point force is avoided to affect the effectiveness of triggering the switch assembly to start or close. At the same time, under the combined action of the elastic member, the support member and the button member, the user only needs to apply a small force and stroke when operating the button member to trigger the switch assembly. The setting of the elastic member enables the button member to generate a gradual and uniform feedback force when it is under pressure. This feedback force not only makes the button member have a better feel during the pressing process, but also can achieve the effect of effectively triggering the switch assembly with a short stroke. In this way, the button device of the present application optimizes the structural design, and the user only needs a small stroke to trigger the switch assembly when pressing the button member, thereby reducing the overall height of the button device. This short stroke design not only makes the button device more compact and beautiful, but also improves the convenience and efficiency of user operation.

[0006] In more detail, the elastic member can be made of a material capable of elastic deformation, such as silicone material.

[0007] In one embodiment, the key member includes a key body and a first protrusion, the first protrusion is arranged on the key body, the first protrusion is used to abut against the elastic member and the switch assembly, the first protrusion can trigger the switch assembly as the key member moves relative to the switch assembly, the contact area is located on the first protrusion, and the support member is located on both sides of the first protrusion. By arranging the first protrusion to abut against the elastic member and the switch assembly, when the key member is pressed, the pressure can directly and effectively act on the elastic member and the switch assembly, thereby realizing a more accurate and efficient trigger mechanism. In addition, since the first protrusion is directly involved in the triggering process, a contact area for triggering the switch assembly is formed on the first protrusion, and the support members are located on both sides of the first protrusion, which not only ensures that the support members can effectively prevent the button member from detaching from the mounting hole, but on the other hand, even if the user does not press directly on the first protrusion, due to the support members arranged on both sides, for example, when one side of the button member is pressed, the support member located on the other side of the button member can stop on the button housing, which can effectively enable the first protrusion located between the support members on both sides to be effectively driven downward to trigger the switch assembly, thereby enabling the button member to respond to the pressing force more quickly, thereby achieving a faster triggering effect and a short-stroke triggering switch assembly effect.

[0008] In one embodiment, the first protrusion is located at the center of the key component, and the support members are symmetrically arranged on both sides of the first protrusion. By arranging the first protrusion at the center of the key component and the support members symmetrically arranged on both sides of the first protrusion, a stable support structure is formed. This symmetrical design enables the key to maintain balance when pressed, avoiding deflection or shaking caused by uneven force, and enables the first protrusion to effectively trigger the switch assembly downward when the edge of the key is pressed, effectively improving the pressing effect and hand feel.

[0009] In one embodiment, the elastic member includes an elastic member body and a second protrusion, the second protrusion is arranged on the elastic member body, the elastic member body and the second protrusion form a first limiting cavity, and the first protrusion is confined in the first limiting cavity. By arranging the second protrusion on the elastic member body and enclosing the first limiting cavity between the elastic member body and the second protrusion, stable limitation of the first protrusion is achieved. This design ensures that when the key is pressed, the first protrusion can always remain in the first limiting cavity, thereby achieving a more stable and reliable triggering mechanism. At the same time, the existence of the first limiting cavity also prevents the first protrusion from shifting or shaking during the triggering process, thereby improving the accuracy of the key operation.

[0010] Furthermore, the second raised portion cooperates with the first raised portion to form a more defined pressing point. When the user presses the button, the feedback force provided by the second raised portion can be felt more directly, thereby obtaining a clearer and more defined pressing feeling. This design helps to improve the user's hand feeling experience, especially in scenarios where precise control of the pressing force is required.

[0011] In one embodiment, the support member includes a first connection portion and a stop portion, the first connection portion is connected between the button member and the stop portion, the stop portion is convexly arranged relative to the first connection portion, and the stop portion is engaged with the side wall of the mounting hole. By arranging the stop portion to be convexly arranged relative to the first connection portion, the support member is more stable in structure. When the button member is pressed, the stop portion close to the side receiving the force can move downward with the button member, and the stop portion away from the side receiving the force can be engaged with the side wall of the mounting hole to stop on the button shell member and can effectively withstand the lateral force. In this process, the force around the button member can be subjected to a downward force through the arrangement of the support member to trigger the switch assembly.

[0012] In one embodiment, the mounting hole is rectangular in shape, the support members include two, the two support members are arranged correspondingly to the opposite sides of the mounting hole, the stopper abuts against the side wall of the mounting hole to form an abutting surface, and the abutting surface is arranged correspondingly along the length direction of the side of the mounting hole. Specifically, the mounting hole is rectangular in shape, and has two sets of oppositely arranged sides, the support members are arranged correspondingly to the opposite sides of the mounting hole, and this symmetrical layout enables the key member to be uniformly stressed when pressed, so that when a certain position of the key member is pressed, the support member at another relative position can be stopped on the key shell as a fulcrum, so that the contact area can also be subjected to downward pressure to trigger the switch assembly. Further, the stopper abuts against the side wall of the mounting hole to form an abutting surface, and the abutting surface is arranged correspondingly along the length direction of the side of the mounting hole. This design enables the support member to fit tightly on the side wall of the mounting hole, providing effective support and limiting effects. When one end of the abutment surface on the same side is pressed and moves downward, the other end of the abutment surface will abut against the key housing. During the force transmission process, the contact area can be effectively triggered to move downward and trigger the switch assembly, so that pressing each area of ​​the key component can effectively trigger the contact area to start the switch assembly, avoiding the problem that pressing other corners will have no effect except for the position close to the switch assembly that can be pressed and powered on, thereby improving the response accuracy and stability of the key device.

[0013] In one embodiment, the support member is arranged around the outside of the contact area to form an enclosing support structure. Since the support member is located outside the contact area, when each area of ​​the key member is pressed, the other side can be stopped on the key cover, so that the contact area located on the inner side of the support member can also be forced downward to effectively trigger the switch assembly, so that the contact can contact the switch assembly more directly and accurately. On the other hand, under the joint action of the support member, the key member and the elastic member, especially in high-frequency or high-force pressing operations, the deformation and damage risks of the key can be significantly reduced.

[0014] In one embodiment, the mounting shell includes a mounting shell body and a mounting portion, the mounting portion is arranged on the mounting shell body, the mounting shell body and the mounting portion are enclosed to form a groove, the key member is at least partially located in the groove, the key member can move relative to the groove and stop on the mounting portion, the mounting portion is provided with the mounting hole, and the groove is connected with the mounting hole. By designing the groove to accommodate the key member, it is ensured that the key can move according to a predetermined trajectory when pressed. The shape and size of the groove can be adjusted according to the design of the key member to achieve more accurate and stable key operation. Moreover, the key member is guided by the groove during the movement, which can avoid deviation or shaking. When the key is pressed to the bottom, it will stop on the mounting portion, thereby ensuring the stability and reliability of the key, and reducing the error or failure that may occur in the key device during operation. Further, the mounting portion is provided with a mounting hole, which makes it easier to install the key device on the electronic device. Through the mounting hole, the key member can be easily assembled with the elastic member and the switch assembly.

[0015] In one embodiment, the mounting housing further comprises a second connection portion, the second connection portion is arranged on the mounting housing body, and the switch assembly is connected to the second connection portion. The switch assembly is connected to the mounting housing body through the second connection portion, thereby enhancing the structural stability of the entire key device, and preventing the switch assembly from loosening or shifting when subjected to external force or vibration, thereby ensuring the normal operation and reliability of the key device.

[0016] In one embodiment, the mounting shell further comprises a convex rib, wherein the convex rib is arranged on the mounting shell body, and the convex rib and the mounting shell body are enclosed to form a second limiting cavity, and the elastic member is nested in the second limiting cavity. The elastic member is stably nested in the second limiting cavity formed by the convex rib and the mounting shell body, thereby effectively preventing the elastic member from shifting or falling off during installation or use, thereby ensuring the stability and reliability of the key device. On the other hand, since the elastic member is restricted by the second limiting cavity, it can be more evenly stressed when pressed, thereby providing the user with a more stable and consistent tactile experience, which is conducive to improving the user's experience of using the key device.

[0033] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0035] The following describes some embodiments of the key device of the utility model with reference to the accompanying drawings.

[0036] like Figures 1 to 10 As shown, a key device comprises a mounting shell 1, wherein the mounting shell 1 is provided with a mounting hole 101; a key member 2, wherein the key member 2 is covered on the mounting shell 1; an elastic member 3 and a switch assembly 5, wherein the switch assembly 5 is arranged on the mounting shell 1, and the elastic member 3 is arranged between the key member 2 and the switch assembly 5, so that the key member 2 can move relative to the switch assembly 5 to trigger the switch assembly 5; a support member 4, wherein the support member 4 is arranged on the key member 2, and the support member 4 can move relative to the mounting shell 1 along with the key member 2, and the other end of the support member 4 abuts against the side wall of the mounting hole 101 to prevent the key member 2 from detaching from the mounting shell 1 from the mounting hole 101, and the key member 2 forms a contact area that can be used to trigger the switch assembly 5, and the support member 4 is located on opposite sides of the contact area.

[0037] The present application discloses a key device, wherein a key component 2 is covered at a mounting hole 101 on a mounting shell 1, an elastic component 3 and a switch assembly 5 are mounted in the mounting shell 1, the elastic component 3 is arranged between the switch assembly 5 and the key component 2, a support component 4 is arranged on opposite sides of a contact area of ​​the key component 2, and can move with the movement of the key component 2 relative to the mounting shell 1, so that when a force is applied to an edge area of ​​the key component 2, the support component 4 close to the force-bearing side of the key component 2 will be pressed down accordingly, and the support component 4 away from the force-bearing side of the key component 2 will be stopped on the mounting shell 1, which is equivalent to the support component 4 away from the force-bearing side of the key component 2 as a fixed fulcrum, so that the contact The area can also be effectively subjected to downward pressing force, and can be pressed downward to effectively trigger the switch assembly 5. In this way, the single-point force is avoided to affect the effectiveness of triggering the switch assembly to start or close. At the same time, under the combined action of the elastic member 3, the support member 4 and the button member 5, when the user operates the button member 2, he only needs to apply a small force and stroke to trigger the switch assembly 5. The setting of the elastic member 3 enables the button member 2 to generate a gradual and uniform feedback force when it is subjected to pressure. This feedback force not only makes the button member 2 have a better feel during the pressing process, but also can achieve the effect of effectively triggering the switch assembly 5 with a short stroke. The button device of the present application optimizes the structural design, and the user only needs a small stroke to trigger the switch assembly when pressing the button member 2, thereby reducing the overall height of the button device. This short stroke design not only makes the button device more compact and beautiful, but also improves the convenience and efficiency of user operation.

[0038] Through the design of the elastic member 3, the button member 2 can move with a short stroke relative to the switch assembly 5, thereby triggering the switch assembly 5. In this way, when the user operates the button, he only needs to apply a small force and stroke to trigger the switch, thereby greatly improving the convenience and efficiency of the user's operation, especially in situations where frequent operation or quick response is required, which can significantly improve the user's experience. Further, the support member 4 is arranged on the opposite sides of the contact area of ​​the button member 2, and can move with the movement of the button member 2 relative to the mounting shell 1. In this way, when the button member 2 is subjected to force, its various parts can evenly distribute the pressure, avoiding the problem of poor feel or key failure caused by excessive force on a single point. At the same time, the other end of the support member 4 abuts against the side wall of the mounting hole 101 to form a stable support structure, further enhancing the stability and effectiveness of the key when pressed. In more detail, when the user presses the button member 2, the setting of the elastic member 3 enables the button to generate a gradual and uniform feedback force when it is subjected to pressure. This feedback force not only makes the button have a better feel during the pressing process, but also ensures that the button has sufficient force when triggering the switch assembly 5. Due to the buffering effect of the elastic member 3, the user will not feel a sudden impact or hard point when pressing the button, thereby improving the feel.

[0039] The key device of the present application optimizes the structural design so that the user only needs a smaller stroke to trigger the switch assembly 5 when pressing the key, thereby reducing the overall height of the key. This short stroke design not only makes the key device more compact and beautiful, but also improves the convenience and efficiency of user operation.

[0040] In more detail, the elastic member 3 can be made of a material capable of producing elastic deformation, such as silicone material.

[0041] like Figure 2 , Figure 4 and Fig.10 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the key member 2 includes a key body 21 and a first protrusion 22, the first protrusion 22 is arranged on the key body 21, the first protrusion 22 is used to abut against the elastic member 3 and the switch assembly 5, the first protrusion 22 can trigger the switch assembly 5 as the key member 2 moves relative to the switch assembly 5, the contact area is located on the first protrusion 22, and the support member 4 is located on both sides of the first protrusion 22. By arranging the first protrusion 22 to abut against the elastic member 3 and the switch assembly 5, when the key member 2 is pressed, the pressure can directly and effectively act on the elastic member 3 and the switch assembly 5, thereby realizing a more accurate and efficient triggering mechanism. In addition, since the first protrusion 22 is directly involved in the triggering process, a contact area for triggering the switch assembly 5 is formed on the first protrusion 22, and the support member 4 is located on both sides of the first protrusion 22, which not only ensures that the support member 4 can effectively prevent the button member 2 from detaching from the mounting hole 101, but on the other hand, even if the user does not press directly on the first protrusion 22, due to the support members 4 arranged on both sides, for example, when one side of the button member 2 is pressed, the support member 4 located on the other side of the button member 2 can stop on the button housing, so that the first protrusion 22 between the support members 4 on both sides can be effectively driven downward to trigger the switch assembly 5, so that the button member 2 can respond to the pressing force more quickly and achieve a faster triggering effect.

[0042] like Figure 2 and Fig.10 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the first protrusion 22 is located at the center of the key member 2, and the support members 4 are symmetrically arranged on both sides of the first protrusion 22. By arranging the first protrusion 22 at the center of the key member 2, and the support members 4 are symmetrically arranged on both sides of the first protrusion 22, a stable support structure is formed. This symmetrical design allows the key to maintain balance when pressed, avoiding deflection or shaking caused by uneven force, so that when the key is pressed, the pressure can be evenly distributed on the entire key surface.

[0043] For more detailed examples, please refer to the attached Figure 2 When the left edge of the button member 2 is subjected to force, the support member 4 on the left side will be subjected to downward pressure and move downward with the button member 2, and the support member 4 on the right side will stop on the button housing, so that the first protrusion 22 located in the center can also move downward to trigger the switch assembly 5. This can avoid the problem of pressing the button member 2 at the edge and affecting the triggering switch effect, which is conducive to forming a button device with a shorter stroke, so that when the user presses in different areas, the overall force of the button member 2 can be more uniform, which is conducive to improving the stability and reliability of the button device, and can also prevent the button from being damaged or failing due to excessive local force.

[0044] like Figure 4 and Fig. 9 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the elastic member 3 includes an elastic member body 31 and a second protrusion 32, the second protrusion 32 is arranged on the elastic member body 31, the elastic member body 31 and the second protrusion 32 enclose a first limiting cavity 301, and the first protrusion 22 is confined in the first limiting cavity 301. By arranging the second protrusion 32 on the elastic member body 31, and enclosing the first limiting cavity 301 between the elastic member body 31 and the second protrusion 32, a stable limitation of the first protrusion 22 is achieved. This design ensures that when the key is pressed, the first protrusion 22 can always remain in the first limiting cavity 301, thereby achieving a more stable and reliable trigger mechanism. At the same time, the existence of the first limiting cavity 301 also prevents the first protrusion 22 from deflecting or shaking during the triggering process, thereby improving the accuracy of the key operation.

[0045] Furthermore, the second protrusion 32 cooperates with the first protrusion 22 to form a more clear pressing point. When the user presses the key member 2, the feedback force provided by the second protrusion 32 can be felt more directly, thereby obtaining a clearer and more specific pressing feeling. This design helps to improve the user's hand feeling experience, especially in scenarios where the pressing force needs to be precisely controlled.

[0046] like Figure 3 and Fig.10As shown, in addition to the features of the above embodiment, this embodiment further defines that: the support member 4 includes a first connection portion 41 and a stop portion 42, the first connection portion 41 is connected between the button member 2 and the stop portion 42, the stop portion 42 is convexly arranged relative to the first connection portion 41, and the stop portion 42 is engaged with the side wall of the mounting hole 101. By arranging the stop portion 42 to be convexly arranged relative to the first connection portion 41, the support member 4 is more stable in structure, when the button member 2 is pressed, the stop portion 42 close to the force-bearing side can move downward with the button member 2, and the stop portion 42 away from the force-bearing side can be engaged with the side wall of the mounting hole 101 to stop on the button shell, and can effectively withstand the lateral force, in this process, the force around the button member 2 can be subjected to a downward force through the arrangement of the support member 4 to trigger the switch assembly 5.

[0047] like Figure 6 , Figure 7 and Figure 8 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the shape of the mounting hole 101 is rectangular, the support members 4 include two, the two support members 4 are arranged corresponding to the opposite sides of the mounting hole 101, the stopper 42 abuts against the side wall of the mounting hole 101 to form an abutting surface 401, and the abutting surface 401 is arranged correspondingly along the length direction of the side of the mounting hole 101. Specifically, the shape of the mounting hole 101 is configured as a rectangle, and the shape has two sets of oppositely arranged sides, and the support members 4 are correspondingly arranged in two and are arranged corresponding to the opposite sides of the mounting hole 101. This symmetrical layout allows the key member 2 to be uniformly stressed when pressed, so that when a certain position of the key member 2 is pressed, the support member 4 at another relative position can be used as a fulcrum to stop on the key shell member, so that the contact area can also be subjected to downward pressure to trigger the switch assembly 5. Furthermore, the stopper 42 abuts against the side wall of the mounting hole 101 to form an abutting surface 401, and the abutting surface 401 is correspondingly arranged along the length direction of the side of the mounting hole 101. This design enables the support member 4 to fit tightly against the side wall of the mounting hole 101, providing effective support and limiting effects. Figure 5 and attached Fig.10 It can be understood that when one end of the abutment surface 401 on the same side is pressed and moves downward, the other end of the abutment surface 401 will abut against the key housing, and in the process of force transmission, the contact area can be effectively triggered to move downward and trigger the switch assembly 5, so that pressing each area of ​​the key member 2 can effectively trigger the contact area to start the switch assembly 5, avoiding the problem that pressing other corners will have no effect except for the position close to the switch assembly 5 that can be pressed and powered on, thereby improving the response accuracy and stability of the key device.

[0048] In other embodiments, the support member 4 is arranged around the outside of the contact area. The support member 4 is arranged around the outside of the contact area to form an enclosing support structure. Since the support member 4 is located outside the contact area, when each area of ​​the key member 2 is pressed, the other side can be stopped on the key shell, so that the contact area located on the inner side of the support member 4 can also be forced downward to effectively trigger the switch assembly 5, so that the contact can contact the switch assembly 5 more directly and accurately. On the other hand, under the joint action of the support member 4, the key member 2 and the elastic member 3, especially in high-frequency or high-force pressing operations, the deformation and damage risks of the key can be significantly reduced.

[0049] like Figure 7 and Figure 8 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the mounting housing 1 includes a mounting shell body 11 and a mounting portion 12, the mounting portion 12 is arranged on the mounting shell body 11, the mounting shell body 11 and the mounting portion 12 enclose a groove 102, the key member 2 is at least partially located in the groove 102, the key member 2 can move relative to the groove 102 and stop on the mounting portion 12, the mounting portion 12 is provided with a mounting hole 101, and the groove 102 is connected to the mounting hole 101. By designing the groove 102 to accommodate the key member 2, it is ensured that the key can move according to a predetermined trajectory when pressed. The shape and size of the groove 102 can be adjusted according to the design of the key member 2 to achieve more accurate and stable key operation. Moreover, the key member 2 is guided by the groove 102 during the movement, which can avoid deviation or shaking. When the key is pressed to the bottom, it will stop on the mounting portion 12, thereby ensuring the stability and reliability of the key and reducing the error or failure that may occur in the key device during operation. Furthermore, the mounting portion 12 is provided with a mounting hole 101 , so that the key device is more convenient to be installed on the electronic device. Through the mounting hole 101 , the key component 2 , the elastic component 3 , and the switch assembly 5 can be conveniently assembled.

[0050] like Figure 8 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the mounting housing 1 further includes a second connection portion 13, the second connection portion 13 is arranged on the mounting housing body 11, and the switch assembly 5 is connected to the second connection portion 13.
