[0029] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 4The switch assembly 1000 includes: a housing 1, a control circuit board 2, a keypad 3, and a cover 4. The housing 1 has a receiving cavity 11 and several key holes 12, all of which communicate with the receiving cavity 11. The control circuit board 2 is housed within the receiving cavity 11 and has several switch portions 21. The control circuit board 2 is used to implement signal transmission, command execution, and on / off functions of the switch button. The keypad 3 has a first surface 31 and a second surface 32 disposed opposite to each other. The first surface 31 has several protrusions 311, and the second surface 32 has several pillars 321, with one pillar 321 aligned with one protrusion 311. The keypad 3 is disposed in the receiving cavity 11, with one protrusion 311 extending from one key hole 12 and one pillar 321 abutting against one switch portion 21. Specifically, the first surface 31 of the keypad 3 abuts against the inner surface of the housing 1 near the control circuit board 2, and the second surface 32 of the keypad 3 abuts against the control circuit board 2, so that the keypad... The controlled circuit board 2 and the housing 1 are clamped together to seal the button hole 12, which serves to prevent dust and water from entering the receiving cavity 11 through the button hole 12. The cover 4 is set on the outer surface of the housing 1 and covers several protrusions 311. Several partition areas 41 are set on the surface of the cover 4 away from the housing 1. Each partition area 41 corresponds to a protrusion 311. Specifically, the cover 4 is used to be pressed, decorated and to distinguish different button areas, so that users can intuitively judge the area of ​​the corresponding function to be used. The above design makes the cover 4 an integrated design, which is convenient for processing and manufacturing and reduces production costs. Moreover, the integrated cover 4 further enhances the waterproof and dustproof properties of the switch assembly 1000 and prevents external dust or water from entering the receiving cavity 11 through the gaps between the individual buttons of the existing switch assembly.

[0032] Understandably, certain markings can be set on the faceplate 4 to help users distinguish the functions of different areas of the faceplate 4, such as printing certain patterns on the faceplate 4 or engraving corresponding patterns on the faceplate 4.

[0033] It should be noted that after the faceplate 4 is pushed up by the protrusion 311, a certain first gap 42 needs to be maintained between it and the corresponding outer surface of the housing 1. This allows the faceplate 4 sufficient room to move when pressed, preventing it from directly contacting the outer surface of the housing 1 and thus affecting its pressing function. Furthermore, the actual distance of the first gap 42 needs to be determined by the length of the protrusion 311 extending out of the button hole 12. Examples will not be provided in this embodiment.

[0034] Furthermore, since the multiple partition areas 41 are located in different positions, and considering that the entire cover 4 will be affected by the pressing action, the partition area 41 located in the middle of the cover 4 should not be pressed to avoid pressing the surrounding partition areas 41 together, which would affect the normal operation of the switch assembly 1000. Alternatively, if the cover 4 is made of a flexible material (i.e., a material that can deform elastically), the impact of pressing the middle partition area 41 on the other partition areas 41 can be disregarded.

[0035] In some embodiments, please refer to Figure 1 The cover 4 is provided with multiple first partition structures 43, which extend along the first direction X. The cover 4 is provided with multiple second partition structures 44, which extend along the second direction Y. The multiple first partition structures 43 and multiple second partition structures 44 are arranged alternately to divide the surface of the cover 4 away from the housing 1 into several partition areas 41. Each partition area 41 corresponds to a different protrusion 311. When one of the partition areas 41 of the cover 4 is pressed, the partition area 41 will transmit the pressing motion to the protrusion 311 of the button pad 3, and then the protrusion 311 of the button pad 3 will transmit the pressing motion to the post 321. The post 321 will transmit the pressing motion to the switch part 21, thereby forming the button function of the switch assembly 1000. The first direction X is perpendicular to the second direction Y.

[0036] It is understood that the first partition structure 43 and the second partition structure 44 include, but are not limited to, partition grooves, partition ridges, partition marks, etc., and the first partition structure 43 and the second partition structure 44 are any one or a combination of two of the above. Specific examples will not be provided one by one.

[0037] In some embodiments, for example, the first partition structure 43 is a first partition groove 431 disposed on the surface of the cover 4 away from the housing 1, and / or the second partition structure 44 is a second partition groove 441 disposed on the surface of the cover 4 away from the housing 1. The first partition groove 431 and the second partition groove 441 are formed by excavating grooves on the surface of the cover 4 away from the housing 1. The arrangement of the first partition groove 431 and the second partition groove 441 makes it easier for the corresponding partition area 41 to deform when the cover 4 is pressed, and has less impact on other partition areas 41.

[0038] Understandably, the material of the cover 4 should be selected to have a low elastic modulus, so as to avoid the rigidity of the cover 4 being too large when a certain partition area 41 is pressed, causing other partition areas 41 to be pressed as well, which would result in the unexpected partition areas 41 being affected by the pressure, causing the corresponding switch part 21 of the other areas to be pressed. For example, the material of the cover 4 is plastic.

[0039] In some embodiments, please refer to Figure 3 and Figure 4 The button pad 3 is recessed from the second surface 32 toward the first surface 31, forming several protrusions 311 on the first surface 31 and several grooves 322 on the second surface 32. A post 321 is fixed to the bottom of a groove 322. The presence of the groove 322 allows the groove wall of the groove 322 to bend and deform when the cover 4 is pressed, so that the pressing motion of the cover 4 can be smoothly transmitted to the switch part 21.

[0040] Understandably, the material of the button pad 3 should be elastically deformable and possess a certain degree of rigidity to ensure the dustproof and waterproof performance of the switch assembly 1000 without affecting the transmission of pressing motion; for example, silicone. Furthermore, the elastically deformable material provides the cover 4 with a deformation margin for accidental activation protection. Specifically, if the button pad 3 is made of a non-elastically deformable material, the contact between the post 321 of the button pad 3 and the switch part 21 will be a "hard-hard" contact. The pressure on the cover 4 will be directly transmitted to the switch part 21 without corresponding deformation margin, leading to a large number of accidental opening or closing of the switch assembly 1000. If the button pad 3 is made of an elastically deformable material, the contact between the post 321 of the button pad 3 and the switch part 21 will be a "soft-hard" contact. The pressing force on the cover 4 needs to be greater than the force required for the elastic deformation of the button pad 3. Therefore, the elastic deformability of the button pad 3 material provides the cover 4 with a deformation margin for accidental activation protection.

[0041] Alternatively, to further enhance the protection against accidental touches on the cover 4, a second gap 33 can be left between the pillar 321 and the control circuit board 2, so that when the cover 4 is pressed along the third direction Z, there is sufficient buffer space when the movement of the cover 4 is transmitted to the control circuit board 2 through the button pad 3. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0042] It should be noted that, along the third direction Z, the width of the second gap 33 is smaller than the width of the first gap 42, so as to avoid the pressing action of the cover 4 not being successfully transmitted to the switch part 21 when the cover 4 is pressed.

[0043] In some embodiments, please refer to Figure 1 The first surface 31 of the button pad 3 is also provided with a plurality of positioning portions 312, which are exemplary in that they are columnar in shape. The housing 1 is also provided with a plurality of positioning holes 13, and one positioning portion 312 is received in one positioning hole 13. Through the cooperation between the positioning portion 312 and the positioning hole 13, the installation and alignment between the housing 1 and the button pad 3 are made more convenient. When assembling the button pad 3, there is no need for automatic assembly fixtures and automatic dispensing machines, which simplifies the assembly process and reduces the assembly cost.

[0044] Furthermore, in order to enhance the waterproof performance between the button pad 3 and the housing 1, the contact area between the first surface 31 of the button pad 3 and the inner surface of the housing 1 is filled with glue to achieve a sealed connection between the button pad 3 and the housing 1 and ensure waterproof performance.

[0045] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The surface of the cover 4 facing the control circuit board 2 is provided with multiple abutment portions 45. For example, the abutment portions 45 are columnar in shape. The protrusion 311 is provided with an abutment hole 3111, which is located on the end face of the protrusion 311. One abutment portion 45 is inserted into the abutment hole 3111 of the protrusion 311. Through the cooperation between the abutment portion 45 and the abutment hole 3111, the alignment and assembly between the cover 4 and the button pad 3 are realized, thereby simplifying the assembly steps between the cover 4 and the button pad 3 and reducing the assembly cost.

[0046] Understandably, the columnar abutting part 45 makes it easier to assemble the cover 4 with the button pad 3, and makes the alignment between the cover 4 and the button pad 3 easier.

[0047] In some embodiments, please refer to Figure 1 The outer surface of the housing 1 is provided with a mounting groove 14, and a number of button holes 12 are located at the bottom of the mounting groove 14. The cover 4 is disposed in the mounting groove 14, and the surface of the cover 4 facing away from the button holes 12 is flush with the outer surface of the housing 1.

[0048] Understandably, the depth of the mounting groove 14 should be greater than or equal to the sum of the depth of the first gap 42 and the thickness of the cover 4, so as to ensure that the cover 4 does not protrude from the switch assembly 1000 as a whole, thereby improving the aesthetics of the switch assembly 1000.

[0049] In some embodiments, please refer to Figure 1 The switch assembly 1000 also includes a lighting assembly 5, which includes an indicator light (not shown) and a light guide (not shown). The indicator light is mounted on the control circuit board 2, and the light guide covers the indicator light. The button pad 3 has a first light guide hole 34, and the cover 4 has a second light guide hole 46. The end of the light guide away from the indicator light passes through the first light guide hole 34 and is inserted into the second light guide hole 46, so that the light guide can smoothly transmit the light signal generated by the indicator light to the external environment. The lighting assembly 5 is used to display the working status and power information of the switch assembly 1000. Furthermore, information such as the company brand name and trademark can be set in the central area, and the content to be displayed can be highlighted by the high brightness of the lighting assembly 5.

[0050] Understandably, in order to comprehensively consider the different positions of the partition area 41 and the impact on other partition areas 41 of the entire cover 4 when it is pressed, for example, the light assembly 5 is set in the middle area of ​​the switch assembly 1000, that is, the signal light is set in the middle of the control circuit board 2, the first light guide hole 34 is set in the middle of the housing 1, and the second light guide hole 46 is set in the middle of the cover 4.

[0051] For housing 1 mentioned above, please refer to... Figure 1 and Figure 4 The housing 1 includes an upper cover 15, a lower housing assembly 16, and a sealing ring 17. A button hole 12 and a positioning hole 13 are both located on the upper cover 15. The upper cover 15 and the lower housing assembly 16 together form a receiving cavity 11. The sealing ring 17 is placed at the mating point between the upper cover 15 and the lower housing assembly 16. The upper cover 15 and the lower housing assembly 16 constitute a detachable switch assembly 1000, facilitating the installation and removal of the control circuit board 2 and the button pad 3 inside the switch assembly 1000. The sealing ring 17 fills the gap between the upper cover 15 and the lower housing assembly 16, improving the waterproofness of the housing 1.

[0052] Understandably, the connection methods of the detachable connection structure between the upper cover 15 and the lower shell assembly 16 include, but are not limited to, screw connection, snap connection, etc.

[0053] In some embodiments, please refer to Figure 4 The upper cover 15 is provided with a slot 151, and a portion of the lower shell assembly 16 is inserted into the slot 151 to connect the upper cover 15 and the lower shell assembly 16. A sealing ring 17 is disposed at the bottom of the slot 151, and the lower shell assembly 16 abuts against the sealing ring 17. The slot 151 guides the connection between the upper cover 15 and the lower shell assembly 16 and extends the path for external dust, water, and other foreign objects to enter the receiving cavity 11, thereby improving the waterproof and dustproof performance of the switch assembly 1000.

[0054] It should be noted that the power source for the control circuit board 2 of the aforementioned switch assembly 1000 can be an external power supply or a removable and replaceable battery.

[0055] In some embodiments, for example, the power source for the control circuit board 2 of the switch assembly 1000 is a removable and replaceable battery 6, therefore a corresponding receiving mechanism is required in the switch assembly 1000 to receive the battery 6. For details, please refer to... Figure 4 The lower housing assembly 16 includes a lower housing body 161, a battery cover 162, and a seal 163. Along the third direction Z, the surface of the lower housing body 161 away from the upper cover 15 is provided with a battery slot (not shown). The battery slot is used to accommodate the battery 6. The battery cover 162 is removably closed to cover the battery slot, and the battery cover 162 and the lower housing body 161 together clamp the seal 163 to seal the battery slot.

[0056] Understandably, the bottom of the battery slot that houses the battery 6 can be directly connected to the control circuit board 2, and the battery 6 can be directly and detachably fixed to the control circuit board 2, thus eliminating the need for a separate connecting wire to connect the battery 6 and the control circuit board 2.

[0057] In this embodiment, the switch assembly 1000 includes: a housing 1, a control circuit board 2, a button pad 3, a cover 4, and a lighting assembly 5. The housing 1 has a receiving cavity 11 and several button holes 12, all of which communicate with the receiving cavity 11. The control circuit board 2 is housed within the receiving cavity 11 and has several switch portions 21. The control circuit board 2 is used to implement signal transmission, command execution, and on / off functions of the switch button. The button pad 3 has a first surface 31 and a second surface 32 disposed opposite to each other. The first surface 31 has several protrusions 311, and the second surface 32 has several pillars 321, with one pillar 321 aligned with one protrusion 311. The button pad 3 is disposed in the receiving cavity 11, with one protrusion 311 extending from one button hole 12 and one pillar 321 abutting against one switch portion 21. Specifically, the first surface of the button pad 3... The second surface 32 of the button pad 3 abuts against the surface of the housing 1 away from the control circuit board 2, so that the button pad 3 is clamped by the control circuit board 2 and the housing 1, thereby sealing the button hole 12 and providing dust and water protection for the switch assembly 1000, reducing the possibility of external dust and water entering the receiving cavity 11 through the button hole 12; the cover 4 is provided on the outer surface of the housing 1 and covers several protrusions 311. The surface of the cover 4 away from the housing 1 is provided with several partition areas 41, and each partition area 41 corresponds to a protrusion 311. Specifically, the cover 4 is used to decorate and distinguish the functions of different button areas, so that users can intuitively judge the area of ​​the corresponding function to be used; the light assembly 5 is connected to the control circuit board 2 and is used to display the working status, power information, etc. of the switch assembly 1000. The above structure makes the faceplate 4 an integrated design, which is convenient for processing and manufacturing, reduces the production cost of the switch assembly 1000, and the integrated faceplate 4 further enhances the waterproof and dustproof properties of the switch assembly 1000, preventing external dust or water and other foreign objects from entering the receiving cavity 11 through the gaps between the existing individual buttons.
