[0045] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is a reference appendix. Figures 1 to 12 This invention describes a button assembly, a switch assembly, and a mobility scooter according to embodiments of the present invention.

[0047] like Figures 1 to 8 As shown, the button assembly of this utility model embodiment includes: a base 1, a button cover 2, a circuit board 3, and a conductive element 4. The button cover 2 has a button cap 21, and the circuit board 3 has a button sensing area 31. The circuit board 3 is located between the button cover 2 and the base 1. The button cap 21 and the button sensing area 31 form a trigger cavity 22. The conductive element 4 is located in the trigger cavity 22 and connected to the button cap 21. Under the action of external force, the button cap 21 can elastically deform towards the button sensing area 31 to push the conductive element 4 into contact with the button sensing area 31.

[0048] According to the embodiment of the present invention, when the button sensing area 31 needs to be triggered, the operator can press the button cap 21 under external force, so that the button cap 21 pushes the conductive element 4 toward the button sensing area 31. When the conductive element 4 contacts the button sensing area 31, the circuit inside the button sensing area 31 can be made conductive, thereby triggering the button sensing area 31. Since the conductive element 4 is connected to the button cover 2, before assembling the button assembly, the conductive element 4 and the button cover 2 can be integrated together first, and then the button cover 2, the base 1, and the circuit board 3 can be assembled. Compared with the assembly process of "button switch and circuit board welding", the design structure and assembly process of the button assembly can be simplified, which is conducive to improving the assembly efficiency of the button assembly.

[0049] It is understandable that the button structure design of traditional technical solutions with built-in switches and switch welding assembly processes is complex, and each switch button is independent of each other, resulting in a large number of components to be assembled. However, the button assembly of the present invention achieves button control by setting a button cap 21 on the button cover 2 and pressing the button cap 21 to trigger the button sensing area 31 on the circuit board 3. This simplifies the structure of the button assembly, improves the assembly efficiency of the button assembly, and meets the requirements of automated assembly.

[0050] For example, the button cover 2 can be an elastic silicone cover, and the button cap 21 can be elastically reset after the external force is released, so that the button switch 7 can be triggered again.

[0051] Optionally, such as Figure 3 As shown, there are multiple button sensing areas 31, which are spaced apart on the circuit board 3. There are also multiple button caps 21 and conductive elements 4. Each button cap 21 corresponds to one of the multiple button sensing areas 31, and each conductive element 4 is installed in one of the multiple trigger cavities 22. It can be understood that the circuit board 3 integrates multiple button sensing areas 31, and each button cap 21 can control the triggering of different button sensing areas 31. This allows for a high degree of integration in the button assembly, further simplifying its structure and enabling modular assembly.

[0052] Optionally, such as Figure 4 As shown, the conductive element 4 and the keycap 21 can be connected by adhesive bonding or heat pressing, which prevents the conductive element 4 from falling off the keycap 21, improves the firmness of the connection between the conductive element 4 and the keycap 21, and helps extend the service life of the key assembly. The structure of the conductive element 4 can be designed according to the power load of the key sensing area 31; that is, different key sensing areas 31 can correspond to different types of conductive elements 4.

[0053] Optionally, such as Figure 6 As shown, the button sensing area 31 includes a first button sensing area 311, and the button cap 21 includes a first button cap 211. The first button cap 211 and the first button sensing area 311 form a first trigger cavity 221. The conductive element 4 includes flexible conductive particles 41, which are disposed in the first trigger cavity 221 and connected to the first button cap 211. When the first button cap 211 moves toward the first button sensing area 311, the flexible conductive particles 41 can move synchronously toward the first button sensing area 311. When the flexible conductive particles 41 come into contact with the first button sensing area 311, they can be deformed under pressure, thereby making the circuit in the first button sensing area 311 conductive and triggering the first button sensing area 311. The button assembly of this embodiment of the present invention designs the conductive element 4 with the above-described structure, which can reduce the manufacturing cost of the conductive element 4 and is suitable for scenarios with low power load.

[0054] For example, the flexible conductive particle 41 is a silicone conductive particle. The silicone conductive particle can be connected to the first button cap 211 by a hot pressing molding process, thereby improving the firmness of the connection between the silicone conductive particle and the first button cap 211.

[0055] Optionally, such as Figure 8 As shown, the button sensing area 31 includes a second button sensing area 312, and the button cap 21 includes a second button cap 212. The second button cap 212 and the second button sensing area 312 form a second trigger cavity 222. The conductive element 4 includes a dome switch 42, which is disposed in the second trigger cavity 222 and connected to the second button cap 212. The arc-shaped surface of the dome switch 42 protrudes towards the side away from the second button sensing area 312. When the second button cap 212 moves toward the second button sensing area 312, the dome switch 42 can move toward the second button sensing area 312 simultaneously. The outer edge of the dome switch 42 contacts the second button sensing area 312 first, and then the middle position of the dome switch 42 deforms under the action of extrusion force and contacts the middle part of the first button sensing area 311, so that the circuit in the second button sensing area 312 is turned on, thereby triggering the second button sensing area 312.

[0056] The button assembly of this utility model has the conductive element 4 designed with the above structure, which makes the conductive element 4 have better resilience and longer service life, and the power load that the dome 42 can withstand is greater than that of the flexible conductive particles 41.

[0057] For example, the dome switch 42 and the second button cap 212 can be glued together, or they can be injection molded together with the button cover 2.

[0058] In other examples, the dome switch 42 can also be soldered or bonded to the circuit board 3.

[0059] Optionally, such as Figure 7 As shown, the button sensing area 31 includes a third button sensing area 313, the button cap 21 includes a third button cap 213, the third button cap 213 and the third button sensing area 313 form a third trigger cavity 223, the conductive component 4 includes a metal conductive block 43, the metal conductive block 43 is provided with a metal protrusion 431, the metal conductive block 43 is disposed in the third trigger cavity 223 and connected to the third button cap 213, and the metal protrusion 431 protrudes towards one side of the third button sensing area 313.

[0060] When the third button cap 213 moves toward the third button sensing area 313, the metal conductive block 43 can move synchronously toward the third button sensing area 313. When the metal protrusion 431 of the metal conductive block 43 contacts the third button sensing area 313, the metal conductive block 43 can make the circuit in the first button sensing area 311 conductive, thereby triggering the third button sensing area 313. The button assembly of this embodiment of the utility model designs the conductive element 4 with the above-described structure, which can be applied to scenarios with high power loads, and has stable electrical contact and good reliability.

[0061] For example, the metal conductive block 43 can be bonded to the third button cap 213 with glue, or it can be injection molded to the button cover 2.

[0062] Optionally, such as Figure 9 As shown, the button sensing area 31 includes a first button sensing area 311, which includes a first conductive part 3111 and a second conductive part 3112. The first conductive part 3111 has multiple first branches 31111, and the second conductive part 3112 has multiple second branches 31121. The first branches 31111 and the second branches 31121 are arranged alternately and at intervals along a preset direction. For example, the first conductive part 3111 and the second conductive part 3112 are both "E" shaped. Because the multiple first branches 31111 and the multiple second branches 31121 are arranged alternately and at intervals along a preset direction, when the conductive element 4 comes into contact with the first button sensing area 311, it can be ensured that the conductive element 4 can conduct normally with the first conductive part 3111 and the second conductive part 3112. This can improve the reliability of the first button sensing area 311 when triggered and reduce the risk of the first button sensing area 311 failing to trigger.

[0063] For example, the conductive element 4 can be a flexible conductive particle 41, which is adapted to the first button sensing area 311.

[0064] In another example, such as Figure 10As shown, the button sensing area 31 includes a second button sensing area 312, which includes a third conductive part 3121 and a fourth conductive part 3122. The third conductive part 3121 surrounds the outside of the fourth conductive part 3122 and is spaced apart from it. For example, the conductive element 4 can be a dome switch 42, which is adapted to the second button sensing area 312. When the dome switch 42 moves toward the second button sensing area 312, it can first contact the third conductive part 3121. Then, under the action of the compressive force, the dome switch 42 undergoes elastic deformation, and the middle position of the dome switch 42 contacts the fourth conductive part 3122, thereby realizing the conduction between the third conductive part 3121 and the fourth conductive part 3122.

[0065] In another example, such as Figure 10 As shown, the button sensing area 31 includes a third button sensing area 313, which includes a fifth conductive part 3131 and a sixth conductive part 3132. The outer periphery of both the fifth conductive part 3131 and the sixth conductive part 3132 is semi-circular and they are arranged at intervals along a preset direction. For example, the conductive element 4 can be a metal conductive block 43, which is adapted to the third button sensing area 313. Since the outer periphery of both the fifth conductive part 3131 and the sixth conductive part 3132 is semi-circular, the reliability of the contact between the metal conductive block 43 and the third button sensing area 313 can be improved, and the risk of trigger failure of the third button sensing area 313 can be reduced.

[0066] Optionally, such as Figures 6 to 8 As shown, the keycap 21 includes a flared portion 2101 and a pressing portion 2102. The inner diameter of the flared portion 2101 gradually increases in the direction toward the key sensing area 31. The pressing portion 2102 is located on the side of the flared portion 2101 away from the key sensing area 31, and the wall thickness of the pressing portion 2102 is greater than the wall thickness of the flared portion 2101. Because the inner diameter of the flared portion 2101 gradually increases in the direction toward the key sensing area 31, the overall shape of the keycap 21 is generally conical, which is beneficial for the compression deformation of the keycap 21. In addition, because the wall thickness of the pressing portion 2102 is greater than the wall thickness of the flared portion 2101, it helps to reduce the probability of the pressing portion 2102 breaking after prolonged pressing, thereby extending the service life of the keycap 21.

[0067] like Figure 4 As shown, the button cover 2 includes a cover body 23 and a button cap 21. The cover body 23 and the button cap 21 are integrally formed. The cover body 23 and the base 1 form a sealed cavity 25, and the circuit board 3 is disposed within the sealed cavity 25. Since the cover body 23 and the button cap 21 are integrally formed, the manufacturing process of the button cover 2 is facilitated, and the sealing effect of the button cover 2 itself is improved. Since the cover body 23 and the base 1 form a sealed cavity 25, water ingress into the circuit board 3 can be prevented.

[0068] For example, a sealing layer is provided at the joint between the cover 23 and the base 1 to further improve the waterproof effect of the button assembly.

[0069] Optionally, such as Figure 3 , Figures 6 to 8 As shown, circuit board 3 is a flexible circuit board, and the button assembly also includes a reinforcing piece 5, which is located on the side of the flexible circuit board 3 facing away from the button cover 2. Because circuit board 3 is flexible, it can be bent into any shape as needed, thus facilitating the planning and arrangement of different button switches 7. Furthermore, since the reinforcing piece 5 is located on the side of the flexible circuit board 3 facing away from the button cover 2, it can support the flexible circuit board 3, improving its compressive strength and extending its service life.

[0070] Optionally, such as Figure 7 As shown, the outer edge of the button cover 2 has a hook portion 24, which engages with the outer edge of the circuit board 3. This improves the stability of the button cover 2 and the circuit board 3 after installation and reduces the probability of the circuit board 3 wobbling relative to the button cover 2.

[0071] like Figure 7 As shown, a slot 241 is formed between the hook portion 24 and the cover 23, and the outer edge of the circuit board 3 and the outer edge of the reinforcing piece 5 are both located in the slot 241.

[0072] like Figure 4 As shown, there are multiple hook parts 24, which are arranged at intervals along the outer edge of the cover 23 to further improve the firmness of the button cover 2 and the circuit board 3 after installation.

[0073] like Figure 11 and Figure 12 As shown, another embodiment of the switch assembly of the present invention includes: a button assembly, a panel 6 and a button switch 7. The button assembly is the button assembly of the present invention. The panel 6 is connected to the base 1. The button switch 7 is movably mounted on the panel 6. The button switch 7 cooperates with the button cap 21. The button switch 7 can squeeze the button cap 21 to trigger the button sensing area 31.

[0074] According to the switch assembly of this utility model, when the button sensing area 31 needs to be triggered, the operator can push the button switch 7 to press the button cap 21. The button cap 21 can push the conductive element 4 towards the button sensing area 31. When the conductive element 4 contacts the button sensing area 31, the circuit inside the button sensing area 31 can be made conductive, thereby triggering the button sensing area 31. Since the conductive element 4 is connected to the button cover 2, before assembling the switch assembly, the conductive element 4 and the button cover 2 can be integrated together first, and then the button cover 2, the base 1, and the circuit board 3 can be assembled. Compared with the assembly process of "soldering the button switch to the circuit board", the design structure and assembly process of the switch assembly can be simplified, which is conducive to improving the assembly efficiency of the switch assembly.

[0075] Another embodiment of the mobility scooter of this utility model includes a button assembly or switch assembly of the present utility model. For example, the mobility scooter can be an electric two-wheeler or a motorcycle.
