Description

Technical Field

[0001] This utility model relates to the field of switch structure technology, and in particular to an adjustable switch controller. Background Technology

[0002] In existing technologies, to enhance user comfort, sofas, home beds, or health beds are typically equipped with electrically driven mechanisms to achieve functions such as posture adjustment and massage. The driving and control of these functions are generally achieved through a separate manual or wired controller. Currently, most such switch controllers on the market are of mechanical structure.

[0003] A typical switch controller includes, in sequence, a lower housing, a PCB circuit board inside the housing, a microswitch mounted on the PCB circuit board, an upper housing connected to the lower housing, and a faceplate covering the surface of the upper housing. The upper housing has a spring-loaded contact. When a user presses the button indicated on the faceplate, the spring-loaded contact on the upper housing deforms, causing a push rod to move until it actuates the microswitch, thus completing a button press action. However, in the aforementioned prior art, different numbers of buttons on the faceplate result in different processing steps and generate different product codes; similarly, different numbers of spring-loaded contacts on the upper housing result in different processing steps and also generate different product codes. Therefore, even when producing switch controllers with the same appearance but different button positions, there are numerous and cumbersome production steps, leading to low production efficiency; simultaneously, there are a large number of product codes, resulting in high production management costs.

[0004] Therefore, there is an urgent need for an adjustable switch controller to solve the above problems. Utility Model Content

The faceplate has multiple button portions and multiple contact portions, with each button portion corresponding to one of the contact portions. Each contact portion can trigger the microswitches. The number of button portions is not greater than the number of through holes. The multiple button portions correspond one-to-one with the multiple through holes, or the multiple button portions correspond one-to-one with some of the through holes.

[0008] Furthermore, the button portion protrudes from the side of the faceplate facing away from the PCB circuit board, and the contact portion is located on the side of the corresponding button portion facing the PCB circuit board.

[0009] Furthermore, the faceplate is provided with a plurality of button holes, and the plurality of button holes are provided one-to-one with a plurality of button parts, and a spring arm is connected between the button part and the corresponding button hole.

[0010] Furthermore, the spring arm is annular, and both the button hole and the button portion are circular.

[0011] Furthermore, the diameter of the button hole is larger than the diameter of the button portion.

[0012] Furthermore, the difference between the diameter of the button hole and the diameter of the button part is in the range of 1-4mm.

[0013] Furthermore, the diameter of the button portion is larger than the diameter of the through hole.

[0014] Furthermore, the difference between the diameter of the button portion and the diameter of the through hole ranges from 1 to 5 mm.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] This embodiment provides an adjustable switch controller. When different types of switch controller structures are required, only different types of faceplates need to be replaced. There are no large and cumbersome production steps, which improves production efficiency and reduces production management costs by eliminating a large number of product codes.

[0028] It should be noted that the adjustable switch controller includes a lower housing, a PCB circuit board, an upper housing, a surface mount, and multiple microswitches. The lower housing and the upper housing are connected, and the PCB circuit board is mounted between the lower housing and the upper housing. The upper housing has multiple through holes. The microswitches are mounted on the PCB circuit board and located between the PCB circuit board and the surface mount. In this embodiment, the microswitches are connected to the PCB circuit board and to the main control unit on the PCB circuit board via signal connection. When the microswitches are subjected to force, they drive the main control unit on the PCB circuit board to issue precise operating commands to the external actuator according to predetermined logic.

[0029] like Figures 1-2As shown, the faceplate 1 of the adjustable switch controller is provided with multiple button sections 11 and multiple contact sections 12. Each button section 11 corresponds to one contact section 12. Each contact section 12 can trigger a microswitch 3. The number of button sections 11 is no greater than the number of through holes 21. The multiple button sections 11 correspond one-to-one with the multiple through holes 21, or multiple button sections 11 correspond one-to-one with some of the through holes 21. It can be understood that with the above configuration, when different types of switch controller structures are required, only different types of faceplates 1 need to be installed, reducing assembly steps. Furthermore, there is no need to process different types of upper housings 2 and upper housing springs. The only difference between different types of faceplates 1 is the number of button sections 11. When processing different types of faceplates 1, only the number of button sections 11 needs to be changed; the processing steps are the same, differing only in the time spent manufacturing the button sections 11. When different types of switch controller structures are required, only different types of faceplates 1 need to be replaced, eliminating numerous and cumbersome production steps, improving production efficiency, and reducing production management costs by avoiding a large number of product codes.

[0030] In this embodiment, the contact portion 12 can pass through the corresponding through hole 21 and abut against the corresponding micro switch 3, so that the main control unit on the PCB circuit board can issue precise operation commands to the external actuator according to the predetermined logic.

[0031] Furthermore, the contact portion 12 can be made of silicone, meaning it has a certain degree of flexibility to avoid damaging the microswitch 3 when it contacts it. Of course, in other embodiments, the contact portion 12 can be made of other materials, such as plastic.

[0032] In this embodiment, multiple microswitches 3 are arranged in a one-to-one correspondence with multiple through holes 21, that is, a microswitch 3 is arranged below each through hole 21. If different types of adjustable switch controllers are needed, only the faceplate 1 needs to be changed, which is convenient to operate.

[0033] Of course, in other embodiments, multiple microswitches 3 can be arranged in a one-to-one correspondence with multiple button portions 11. That is, the number and position of microswitches 3 are determined by the number and position of button portions 11 on different surfaces 1, which can meet the corresponding requirements and eliminate the need to set multiple microswitches 3, thereby saving production costs and improving economic efficiency.

[0034] Furthermore, the button portion 11 protrudes from the side of the faceplate 1 facing away from the PCB circuit board, and the contact portion 12 is located on the side of the corresponding button portion 11 facing the PCB circuit board. It is understood that by providing the button portion 11 protruding from the base layer of the faceplate 1 on the side facing away from the PCB circuit board, it is convenient for the user to contact the button portion 11 and apply pressure to it, and it also provides sufficient distance for deformation to operate the adjustable switch controller. The contact portion 12 is located on the side of the corresponding button portion 11 facing the PCB circuit board, facilitating contact between the contact portion 12 and the micro switch 3.

[0035] To facilitate the installation of the faceplate 1 onto the upper housing 2 and improve the stability of the faceplate 1 installation, in this embodiment, the faceplate 1 further includes an adhesive layer. The adhesive layer is located on the side of the faceplate 1 away from the button portion 11. The adhesive layer can adhere the faceplate 1 to the upper housing 2 to achieve the installation of the faceplate 1. By setting the adhesive layer, the space occupied by the entire controller when installing the faceplate 1 is reduced, and it is easy to operate without drilling or installing other fixing structures, resulting in a simple structure.

[0036] Furthermore, the faceplate 1 is provided with multiple button holes 14, each corresponding to a button part 11. A spring arm 13 connects the button part 11 to its corresponding button hole 14. It is understood that by providing button holes 14 corresponding to the button parts 11, the contact part 12 can easily abut against the corresponding micro switch 3 through the corresponding button hole 14. Furthermore, the spring arm 13 connects the button part 11 to its corresponding button hole 14, ensuring the stability of the button part 11's movement while allowing it to be installed. When the button part 11 is subjected to force, it can drive the contact part 12 to abut against the corresponding micro switch 3. After abutting, if the user withdraws the applied force, the spring arm 13 can provide a force to move the button part 11 back to its original position, facilitating the automatic reset of the button part 11. In this embodiment, the spring arm 13 can be made of a flexible material, such as rubber.

[0037] Furthermore, it can be inferred that the spring arm 13 is annular, and both the button hole 14 and the button portion 11 are circular. Specifically, there are rounded corners between the spring arm 13 and the corresponding button portion 11, as well as between the spring arm 13 and the corresponding button portion 11. It can be understood that by providing annular spring arm 13, and circular button holes 14 and button portions 11, with rounded corners between the spring arm 13 and the corresponding button holes 14, and between the spring arm 13 and the corresponding button portion 11, the spring arm 13, while connecting the button portion 11 and the button hole 14, ensures a smooth connection between the spring arm 13, the button hole 14, and the button portion 11. This facilitates deformation when the button portion 11 is pressed, making it easier for the contact portion 12 to engage the microswitch. Furthermore, the rounded corners improve the user's tactile experience.

[0038] In this embodiment, the faceplate 1 sequentially includes a surface layer, a base layer, a contact portion 12, an adhesive layer, and a release layer. The button portion 11 can be formed by embossing the base layer. The adhesive layer and release layer have holes in the embossed area of ​​the base layer (i.e., the area with the button portion 11), and the contact portion 12 is provided on the opposite side of the button portion 11 in the base layer. When the release layer is peeled off, the faceplate 1 can be adhered to the outer surface of the upper housing 2 through the adhesive layer, and the button hole 14 corresponds to the position of the corresponding through hole 21, so that the position of the contact portion 12 inserted into the through hole 21 of the upper housing 2 is close to the position of the micro switch 3. Embossing refers to a processing technique, also called debossing or embossing, which uses a pair of embossed molds to apply pressure to a film or paper, causing the button area to bulge upwards from a flat surface, forming a small bump. This bump allows users to quickly locate the button by touch during blind operation and also visually highlights the functional area, often in conjunction with icons and text printed on the surface to indicate the button position. This is prior art in the field and will not be described further in this embodiment.

[0039] In this embodiment, the button portion 11, button hole 14, and spring arm 13 on the faceplate 1 can be integrally molded, that is, they can be integrally molded on the base layer. The contact portion 12 can be fixed to the side of the button portion 11 facing the PCB circuit board by means of bonding or other methods.

[0040] Furthermore, the diameter of the button hole 14 is larger than the diameter of the button portion 11, and the diameter of the button portion 11 is larger than the diameter of the through hole 21. Specifically, the difference between the diameter of the button hole 14 and the diameter of the button portion 11 ranges from 1 to 4 mm. The difference between the diameter of the button portion 11 and the diameter of the through hole 21 ranges from 1 to 5 mm. For example, the diameter of the button hole 14 is 12 mm, the diameter of the button portion 11 is 10 mm, and the diameter of the through hole 21 is 7.4 mm.

[0041] For example, the contact portion 12 is frustum-shaped, with its larger end facing the button portion 11. It is understood that by providing a frustum-shaped contact portion 12 with its larger end facing the button portion 11, and its smaller end located away from the button portion 11, the smaller end of the contact portion 12 facilitates contact between itself and the micro switch 3. Simultaneously, the larger end of the contact portion 12 contacts the back of the button portion 11, facilitating movement of the contact portion 12 by the button portion 11. In this embodiment, the axial length of the contact portion 12 is greater than the surface layer thickness of the upper housing 2. For example, the axial length of the contact portion 12 is 2.25 mm, and the surface layer thickness of the upper housing 2 is 1 mm, meaning the axial length of the through hole 21 is 1 mm.

[0042] In other embodiments, a top post can be provided between the micro switch 3 and the contact portion 12. This allows the axial length of the contact portion 12 to be less than large, ensuring the stability of the contact portion 12 during movement. Furthermore, only a slight press of the button portion 11 is needed to drive the contact portion 12 to abut against the end face of the top post and move the top post.

[0043] Furthermore, button sections 11 are provided with button patterns, and different button sections 11 have different button patterns. By setting different button patterns, users can easily distinguish buttons with different functions, making it easier to use.

[0044] In this embodiment, button patterns can be printed on the surface layer, and the positions of the button patterns printed on the surface layer correspond to the button portion 11. Alternatively, button patterns can be printed on the button portion 11, and a transparent layer can be provided on the surface layer. A hollowed-out button pattern can also be formed on the button portion 11, and an ink with light-blocking properties can be printed on the surface layer, allowing light to be scattered from the corresponding area when the button portion 11 is pressed.

[0045] In this embodiment, the hardness of the base layer is greater than that of the button portion 11, the hardness of the button portion 11 is greater than that of the spring arm 13, and the hardness of the spring arm 13 is greater than that of the contact portion 12. When a user's finger applies external force to the button portion 11, the spring arm 13 deforms first, thereby driving the contact portion 12 to move, causing the contact portion 12 to move towards the micro switch 3, thus activating the switch. As the external force further increases, it can also promote the deformation of the button portion 11, further increasing the movement path of the contact portion 12.

[0046] In this embodiment, the working principle is as follows: When different types of adjustable switch controller structures are required, a faceplate 1 that meets the usage requirements is used. The faceplate 1 is bonded to the upper housing 2 through an adhesive layer. The button portion 11 on the faceplate 1 corresponds to the through hole 21 of the upper housing 2 and also corresponds to the micro switch 3. Pressing different button portions 11 will drive different contact portions 12 to move, thereby triggering the corresponding micro switch 3. In this embodiment, the multiple faceplates 1 differ only in the number of button portions 11. The arrangement is the same as the arrangement of the through holes 21 on the upper housing 2. There is no need to manufacture different types of upper housings 2 and faceplates 1 with different arrangements of button portions 11. There are no large number of cumbersome production steps, which improves production efficiency and reduces production management costs by eliminating a large number of product codes.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
