Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, specifically to a switch assembly and a mobility scooter. Background Technology

[0002] Personal mobility vehicles such as electric bikes and motorcycles have become one of the main modes of transportation due to their ease of operation and parking. The various functions of these vehicles are generally achieved through different push-button switches on a switch assembly. However, in related technologies, the switch assembly uses multiple push-button switches, leading to accidental activation by users and reducing the user experience. Furthermore, the switch assembly has a complex internal structure and high manufacturing and assembly costs. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a switch assembly with a reasonable structural arrangement, which can reduce the probability of accidental switch activation during use and improve the user experience.

[0005] An embodiment of this utility model also proposes a mobility scooter.

[0006] The switch assembly of this utility model includes: a roller module, the roller module including a roller, a swing bracket and a fixed base, the roller being connected to the swing bracket and the swing bracket being connected to the fixed base, the swing bracket having a first rotation axis and the roller having a second rotation axis, the first rotation axis and the second rotation axis having an angle; a circuit board, the circuit board being provided with a sensing element and a plurality of switching elements, the sensing element being used to sense the rotation of the roller, at least two of the switching elements being respectively arranged on both sides of the first rotation axis, and the swing bracket being able to trigger the corresponding switching element when swinging around the second rotation axis.

[0007] According to the switch assembly of the present invention, the rotation of the roller can be sensed by the sensing element to control the relevant functions of the mobility scooter. Since at least two switching elements are respectively arranged on both sides of the first rotation axis, when the swing bracket swings around the second rotation axis, the corresponding switching element can be triggered. Compared with the scheme of "two switching elements are arranged on the same side of the first rotation axis", the problem of accidental touch of different switching elements can be reduced. Therefore, the switch assembly of the present invention has a reasonable structural arrangement, which can reduce the probability of accidental switch touch during use and improve the user experience.

[0008] In some embodiments, the switching element includes a first switch, a second switch, and a third switch. The first switch and the second switch are respectively arranged on both sides of the first rotation axis, and the third switch is disposed between the first switch and the second switch. When the swing bracket is subjected to pressure near the region of the first rotation axis, the swing bracket can trigger the third switch; when the swing bracket is subjected to pressure away from the region of the first rotation axis, the swing bracket can trigger one of the first switch and the second switch.

[0009] In some embodiments, the swing bracket has a limiting block disposed between the first switch and the second switch, and the fixed base has a limiting groove. When the swing bracket is subjected to pressure near the first rotation axis region, the limiting block can cooperate with the limiting groove to restrict the swing bracket from rotating around the first rotation axis. When the swing bracket is subjected to pressure away from the first rotation axis region, the limiting block is spaced apart from the limiting groove so that the swing bracket can rotate around the first rotation axis.

[0010] In some embodiments, the fixed base is provided with a movable groove, and the movable groove is provided with a first stop surface and a second stop surface on both radial sides along the first rotation axis. The limiting groove is provided at the bottom of the movable groove and is located between the first stop surface and the second stop surface. When the swing bracket is subjected to pressure deviating from the first rotation axis region, the limiting block can stop against one of the first stop surface and the second stop surface.

[0011] In some embodiments, the switch assembly further includes a base and a protective cover, the protective cover and the base forming a sealed cavity, the circuit board being disposed within the sealed cavity, the protective cover being disposed between the fixing seat and the circuit board, and the protective cover being elastic, and the fixing seat being connected to the base.

[0012] In some embodiments, the inner peripheral wall of the protective cover is provided with an annular groove, and the outer peripheral edge of the circuit board fits into the annular groove.

[0013] In some embodiments, the base has a first protrusion on the side facing the protective cover, the first protrusion is arranged circumferentially around the base, and the first protrusion elastically abuts against the protective cover.

[0014] In some embodiments, the outer periphery of the protective cover has an annular flange that abuts against the base.

[0015] In some embodiments, one of the fixing base and the base is provided with a latching protrusion, and the other is provided with a buckle, wherein the latching protrusion and the buckle engage in a latching engagement.

[0016] In some embodiments, the roller module further includes a cover plate, the cover plate and the swing bracket forming a mounting cavity, at least a portion of the roller being located within the mounting cavity, and a stop portion being provided within the mounting cavity, the stop portion abutting against the roller along the radial direction of the second rotation axis and the axial direction of the second rotation axis.

[0017] In some embodiments, the roller includes a connected roller body and a support shaft, and the stop includes a first stop disposed on the cover plate. The first stop abuts against at least one of the roller body and the support shaft along the radial direction of the second rotation axis and the axial direction of the second rotation axis.

[0018] In some embodiments, the roller includes a connected roller body and a support shaft, and the stop includes a second stop disposed on the swing bracket. The second stop abuts against at least one of the roller body and the support shaft along the radial direction of the second rotation axis and the axial direction of the second rotation axis.

[0019] In some embodiments, the roller includes a roller body and a support shaft. The support shaft includes a connected shaft body and a fixed disk. The fixed disk is provided with a positioning post. The positioning post and the shaft body are radially spaced apart along the second rotation axis. Both the shaft body and the positioning post pass through the roller body along the second rotation axis.

[0020] In some embodiments, the roller includes a roller body and a support shaft. The support shaft includes a connected shaft body and a fixed disk. The shaft body passes through the roller body along the second rotation axis, and the fixed disk is thermally riveted to one axial end of the roller body.

[0021] In some embodiments, the roller has a plurality of receiving slots arranged at intervals along the circumference of the roller. The roller module also includes a plurality of magnetic components, which are installed one-to-one in the plurality of receiving slots. The wall of the receiving slot has a second protrusion, which is interference-fitted with the magnetic component.

[0022] Another example of the present invention is a mobility scooter that includes the switch assembly described in any one of the embodiments of the present invention.

[0023] According to the embodiments of the present invention, the mobility scooter can sense the rotation of the rollers through a sensing element to control the relevant functions of the mobility scooter. Since at least two switching elements are respectively arranged on both sides of the first rotation axis, when the swing bracket swings around the second rotation axis, the corresponding switching element can be triggered. Compared with the scheme of "two switching elements are arranged on the same side of the first rotation axis", the problem of accidental touch of different switching elements can be reduced.

[0048] 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.

[0049] The following is a reference appendix. Figures 1 to 16 This invention describes a switch assembly and a mobility scooter according to embodiments of the present invention.

[0050] like Figures 1 to 10As shown, the switch assembly of this utility model embodiment includes: a roller module 1 and a circuit board 2. The roller module 1 includes a roller 11, a swing bracket 12 and a fixed base 13. The roller 11 is connected to the swing bracket 12, and the swing bracket 12 is connected to the fixed base 13. The swing bracket 12 has a first rotation axis, and the roller 11 has a second rotation axis. The first rotation axis and the second rotation axis have an angle.

[0051] It is understandable that the swing bracket 12 can swing left and right relative to the fixed seat 13 around the first rotation axis, and the roller 11 can rotate clockwise and counterclockwise relative to the swing bracket 12 around the second rotation axis.

[0052] like Figure 2 and Figure 9 As shown, the circuit board 2 is provided with a sensing element 21 and multiple switching elements 22. The sensing element 21 is used to sense the rotation of the roller 11. When the roller 11 rotates clockwise or counterclockwise, the sensing element 21 can sense the rotation of the roller 11 and generate different sensing signals. At least two switching elements 22 are respectively arranged on both sides of the first rotation axis. When the swing bracket 12 swings around the second rotation axis, it can trigger the corresponding switching element 22.

[0053] According to the switch assembly of the present invention, the rotation of the roller 11 can be sensed by the sensing element 21 to control the relevant functions of the mobility scooter. Since at least two switching elements 22 are respectively arranged on both sides of the first rotation axis, when the swing bracket 12 swings around the second rotation axis, the corresponding switching element 22 can be triggered. Compared with the scheme of "two switching elements 22 are arranged on the same side of the first rotation axis", the problem of accidental touch of different switching elements 22 can be reduced. Therefore, the structural arrangement of the switch assembly of the present invention is reasonable, which can reduce the probability of accidental touch of the switch during use, which is beneficial to the user experience. In addition, the internal structure of the switch assembly is simple and easy to manufacture and assemble.

[0054] For example, the first rotation axis is arranged orthogonally to the second rotation axis. Figure 4 As shown, the first axis of rotation extends in the front-to-back direction, and the second axis of rotation extends in the left-to-right direction.

[0055] Optionally, such as Figure 2 , Figure 5 and Figure 9As shown, the switching element 22 includes a first switch 221, a second switch 222, and a third switch 223. The first switch 221 and the second switch 222 are respectively arranged on both sides of the first rotation axis, and the third switch 223 is disposed between the first switch 221 and the second switch 222. When the swing bracket 12 is subjected to pressure in the region close to the first rotation axis, the swing bracket 12 can trigger the third switch 223. When the swing bracket 12 is subjected to pressure in the region away from the first rotation axis, the swing bracket 12 can trigger one of the first switch 221 and the second switch 222.

[0056] Understandably, when the swing bracket 12 is subjected to pressure near the first rotation axis region, the swing bracket 12 can pitch in the front-to-back direction. When the pressure on the swing bracket 12 is large enough, the swing bracket 12 can trigger the third switch 223. When the swing bracket 12 is subjected to pressure deviating from the first rotation axis region, the swing bracket 12 can swing in the left-to-right direction.

[0057] like Figure 5 As shown, when the swing bracket 12 is subjected to pressure deviating to the left from the first rotation axis region, the first switch 221 can be triggered by the swing bracket 12. When the swing bracket 12 is subjected to pressure deviating to the right from the first rotation axis region, the second switch 222 can be triggered by the swing bracket 12. This allows the multiple switching elements 22 to be arranged compactly, and the problem of accidental activation between the multiple switching elements 22 is not easily encountered.

[0058] Optionally, such as Figure 5 and Figure 6 As shown, the swing bracket 12 has a limiting block 121, which is positioned between the first switch 221 and the second switch 222 in the left-right direction. The fixed base 13 has a limiting groove 131. When the swing bracket 12 is subjected to pressure near the first rotation axis, the limiting block 121 can cooperate with the limiting groove 131 to restrict the swing bracket 12 from rotating around the first rotation axis. This avoids the problem of the swing bracket 12 accidentally triggering the first switch 221 or the second switch 222 when it triggers the third switch 223. When the swing bracket 12 is subjected to pressure deviating from the first rotation axis, the limiting block 121 and the limiting groove 131 are separated, thereby releasing the restriction on the rotation of the swing bracket 12 so that the swing bracket 12 can rotate around the first rotation axis.

[0059] like Figure 6 and Figure 7As shown, the fixed base 13 is provided with a movable groove 132. A first stop surface 1321 and a second stop surface 1322 are respectively provided on both radial sides of the movable groove 132 along the first rotation axis. A limiting groove 131 is located at the bottom of the movable groove 132 and is situated between the first stop surface 1321 and the second stop surface 1322. When the swing bracket 12 is subjected to pressure deviating from the first rotation axis region, the limiting block 121 can abut against one of the first stop surface 1321 and the second stop surface 1322. Under the constraint of the first stop surface 1321 and the second stop surface 1322, the problem of accidental activation of the third switch 223 when the swing bracket 12 is pressed with its left or right offset can be avoided, further improving the anti-accidental activation effect of the switch assembly.

[0060] Optionally, such as Figures 9 to 11 As shown, the switch assembly also includes a base 31 and a protective cover 32. The protective cover 32 and the base 31 form a sealed cavity 33. The circuit board 2 is disposed within the sealed cavity 33. The protective cover 32 is located between the fixed base 13 and the circuit board 2, and the protective cover 32 is elastic. The fixed base 13 is connected to the base 31. It can be understood that, due to the elasticity of the protective cover 32, the swing bracket 12 can trigger the switching element 22 by squeezing the protective cover 32. Since the circuit board 2 is disposed within the sealed cavity 33 formed by the protective cover 32 and the base 31, the circuit board 2 is prevented from being exposed to the outside environment, thereby improving the waterproof sealing effect of the circuit board 2.

[0061] For example, such as Figure 10 and Figure 11 As shown, the inner peripheral wall of the protective cover 32 is provided with an annular groove 321, and the outer peripheral edge of the circuit board 2 fits into the annular groove 321. The annular groove 321 limits the circuit board 2, thereby increasing the contact area between the outer edge of the protective cover 32 and the circuit board 2, so as to improve the waterproof sealing effect of the sealing cavity 33.

[0062] like Figure 10 and Figure 11 As shown, the base 31 has a first protrusion 311 on the side facing the protective cover 32. The first protrusion 311 is arranged circumferentially around the base 31 and elastically abuts against the protective cover 32. It can be understood that, since the protective cover 32 is elastic, when the base 31 and the protective cover 32 are assembled, the first protrusion 311 can be inserted into the protective cover 32 by interference fit, thereby increasing the contact area between the base 31 and the protective cover 32 and improving the waterproof sealing effect of the sealing cavity 33.

[0063] For example, the first protrusion 311 can be a toothed structure.

[0064] like Figure 10 and Figure 11As shown, the outer periphery of the protective cover 32 has an annular flange 322, which abuts against the base 31, thereby increasing the contact area between the base 31 and the protective cover 32 and further improving the waterproof sealing effect of the sealing cavity 33.

[0065] Optionally, such as Figure 9 As shown, one of the fixing base 13 and the base 31 is provided with a locking protrusion 312, and the other is provided with a buckle 133. The locking protrusion 312 and the buckle 133 engage with each other, thereby eliminating the need for threaded fasteners and improving the ease of assembly and disassembly of the fixing base 13 and the base 31.

[0066] For example, such as Figure 9 As shown, the fixing base 13 is provided with a buckle 133, and the base 31 is provided with a buckle protrusion 312. There are multiple buckles 133, and multiple buckles 312 are arranged at intervals along the circumference of the fixing base 13. There are multiple buckles 312, and multiple buckles 312 are arranged at intervals along the circumference of the base 31.

[0067] In some embodiments, such as Figure 12 As shown, the roller module 1 also includes a cover plate 14, which, together with the swing bracket 12, forms a mounting cavity 15. At least a portion of the roller 11 is located within the mounting cavity 15. A stop portion 16 is provided within the mounting cavity 15, and the stop portion 16 abuts against the roller 11 radially along and axially along the second rotation axis. Under the constraint of the stop portion 16, the roller 11 can be restricted from moving axially or radially, which helps to improve the stability of the roller 11 after installation.

[0068] For example, the cover plate 14, the swing bracket 12 and the fixed base 13 are all made of plastic, which can reduce the production cost of the switch assembly.

[0069] Specifically, such as Figure 12 As shown, the roller 11 includes a connected roller body 111 and a support shaft 112. The stop part 16 includes a first stop part 161, which is disposed on the cover plate 14. The first stop part 161 abuts against at least one of the roller body 111 and the support shaft 112 along the radial direction of the second rotation axis and the axial direction of the second rotation axis, thereby further improving the stability of the roller 11 after installation.

[0070] For example, such as Figure 12 As shown, the first stop portion 161 can be a ring-shaped boss structure. The first stop portion 161 abuts against the support shaft 112 radially along the second rotation axis, and the first stop portion 161 abuts against the support shaft 112 axially along the second rotation axis.

[0071] like Figure 12As shown, the stop portion 16 includes a second stop portion 162, which is disposed on the swing bracket 12. The second stop portion 162 abuts against at least one of the roller body 111 and the support shaft 112 along the radial direction of the second rotation axis and the axial direction of the second rotation axis.

[0072] For example, such as Figure 12 As shown, the second stop portion 162 can be a ring-shaped boss structure. The second stop portion 162 abuts against the support shaft 112 along the axial direction of the second rotation axis, and the second stop portion 162 abuts against the support shaft 112 along the radial direction of the second rotation axis.

[0073] Optionally, such as Figures 13 to 15 As shown, the support shaft 112 includes a connected shaft body 1121 and a fixed disk 1122. A positioning post 1123 is provided on the fixed disk 1122. The positioning post 1123 and the shaft body 1121 are radially spaced along the second rotation axis. Both the shaft body 1121 and the positioning post 1123 pass through the roller body 111 along the second rotation axis. Thus, the positioning post 1123 can restrict the rotation of the support shaft 112 relative to the roller body 111, which helps improve the stability of the roller body 111 and the support shaft 112 after installation.

[0074] For example, there may be two or more positioning posts 1123, with at least two positioning posts 1123 arranged radially along the shaft 1121 on both sides of the fixed disk 1122.

[0075] Optionally, such as Figure 2 and Figure 12 As shown, the switch assembly also includes an elastic component 6, which includes an elastic element 61 and a connecting post 62. One end of the elastic element 61 is connected to the connecting post 62, and the elastic element 61 presses the connecting post 62 in the direction of the support shaft 112 so that the connecting post 62 elastically abuts against the side wall of the support shaft 112.

[0076] For example, such as Figure 2 and Figure 12 As shown, one end of the shaft 1121 is provided with a gear wheel 1124. The outer wall of the gear wheel 1124 is provided with multiple circumferentially arranged grooves. The connecting column 62 abuts against the grooves, thereby providing a certain damping force for the rotation of the roller 11.

[0077] Optionally, such as Figure 15 and Figure 16As shown, the roller 11 has multiple receiving slots 1111, which are arranged at intervals along the circumference of the roller 11. The roller module 1 also includes multiple magnetic components 5, which are installed one-to-one in the multiple receiving slots 1111. The wall surface of the receiving slot 1111 has a second protrusion 1112, which is interference-fitted with the magnetic component 5. Because the second protrusion 1112 is interference-fitted with the magnetic component 5, the firmness of the magnetic component 5 after assembly can be improved, thus preventing the probability of the magnetic component 5 shaking relative to the receiving slot 1111 and improving the sensing accuracy of the sensing element 21.

[0078] like Figure 13 and Figure 15 As shown, the fixed disk 1122 is thermally riveted to one end of the roller body 111 in the axial direction to cover the receiving groove 1111, thereby preventing the magnetic component 5 from falling out of the receiving groove 1111. In addition, the thermal riveting connection between the fixed disk 1122 and the roller body 111 can improve the firmness of the assembly of the fixed disk 1122, the roller body 111 and the magnetic component 5.

[0079] For example, such as Figure 16 As shown, there can be multiple second protrusions 1112, which are spaced apart within the receiving groove 1111. For example, the second protrusions 1112 can be toothed structures.

[0080] For example, the sensing element 21 can be a Hall element, and the magnetic element 5 can be a magnet.

[0081] like Figure 1 As shown, the switch assembly also includes a housing 7, and components such as the roller module 1 and the circuit board 2 are all located on the housing 7. For example, other types of push-button switches 4 can be arranged on the housing 7 to facilitate the control of the mobility scooter.

[0082] Another embodiment of this utility model is a mobility scooter, which includes the switch assembly of this utility model. Exemplarily, the mobility scooter can be an electric vehicle or a motorcycle.

[0083] According to the embodiments of the present invention, the mobility scooter can sense the rotation of the roller 11 through the sensing element 21 to control the relevant functions of the mobility scooter. Since at least two switching elements 22 are respectively arranged on both sides of the first rotation axis, when the swing bracket 12 swings around the second rotation axis, the corresponding switching element 22 can be triggered. Compared with the solution of "two switching elements 22 are arranged on the same side of the first rotation axis", the problem of accidental activation of different switching elements 22 can be reduced. Therefore, the switch assembly structure of the mobility scooter of the present invention is reasonably arranged, which can reduce the probability of accidental activation of switches during use and improve the user experience.
