[0040] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0041] The switching device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0042] like Figures 1-7 As shown, the switch device 1 according to an embodiment of the present utility model includes a fixed base 100, a keycap 200 and a first sealing ring 300.

[0043] The fixed base 100 has a receiving cavity 110, and a micro switch assembly 700 is provided in the receiving cavity 110. The keycap 200 is slidably connected to the fixed base 100, and when the keycap 200 slides toward the micro switch assembly 700, it presses the micro switch assembly 700. The first sealing ring 300 is sleeved on the keycap 200 and supported by the fixed base 100. The first sealing ring 300 includes a radial sealing part 310 and an axial sealing part 320. The radial sealing part 310 is connected to the radial inner side of the axial sealing part 320. The radial sealing part 310 abuts and seals with the outer peripheral surface of the keycap 200, and the axial side of the axial sealing part 320 is adapted to abut and seal with the charging port cover plate 600.

[0044] The radial sealing portion 310 is axially deformable along the first sealing ring 300 to provide an elastic force for the keycap 200 to slide away from the micro switch assembly 700.

[0045] The height of the mounting base 100 can be adjusted according to the model of the vehicle's charging port cover plate 600 so that the switch device 1 can be better assembled with the charging port cover plate 600. Specifically, the charging port cover plate 600 can be sleeved on the outside of the switch device 1.

[0046] In addition, the micro switch assembly 700 can be installed on the lower side of the receiving cavity 110, the keycap 200 can be located on the upper side of the receiving cavity 110, and the keycap 200 can be exposed from the upper side of the receiving cavity 110. The lower end of the keycap 200 can abut against the micro switch 720 so that the user can press the micro switch 720 by squeezing the keycap 200.

[0047] Furthermore, a protrusion 330 may be constructed on the axial lower side of the first sealing ring 300. The protrusion 330 protrudes from the lower side of the first sealing ring 300 and can extend into the receiving cavity 110 and abut against the inner wall of the receiving cavity 110. This can radially limit the first sealing ring 300 and the fixing seat 100, which is beneficial to improving the fixing stability of the first sealing ring 300 in the radial direction of the fixing seat 100.

[0048] Furthermore, by constructing a protrusion 330 on the axially lower side of the first sealing ring 300, the structural features of the upper and lower sides of the first sealing ring 300 can be significantly different. This allows the protrusion 330 to distinguish the upper and lower sides of the first sealing ring 300; for example, the side of the first sealing ring 300 with the protrusion 330 is the lower side, and vice versa. Moreover, the inner wall of the receiving cavity 110 also needs to be provided with a corresponding groove to accommodate the protrusion 330. Therefore, when assembling the first sealing ring 300 with the fixing seat 100, the reverse installation of the first sealing ring 300 can be effectively avoided, thus preventing assembly errors. The assembly of the first sealing ring 300 can be more accurate, convenient, and efficient.

[0049] Furthermore, after the protrusion 330 fits into the groove on the inner wall of the receiving cavity 100, the side wall of the groove can abut against the outer peripheral wall of the protrusion 330, thereby restricting the rotation of the first sealing ring 300 and making the assembly and positioning of the first sealing ring 300 more stable and reliable.

[0050] According to the switch device 1 of this utility model embodiment, by sleeved a first sealing ring 300 on the keycap 200 and supported on the fixed base 100, one axial side of the axial sealing part 320 is adapted to abut and seal against the charging port cover plate 600. For example, the lower side of the first sealing ring 300 can be supported on the fixed base 100, and the upper side of the axial sealing part 320 can abut and seal against the charging port cover plate 600. In this way, not only can the first sealing ring 300 be sealed with the fixed base 100 along the axial direction, but the fixed base 100 and the charging port cover plate 600 can also limit the first sealing ring 300 along the axial direction, thereby preventing the first sealing ring 300 from moving along the axial direction of the charging port cover plate 600. Therefore, when the keycap 200 is pressed, that is, when the keycap 200 moves along the axial direction of the charging port cover plate 600, the first sealing ring 300 can be prevented from moving relative to the charging port cover plate 600. This can significantly reduce the wear caused by friction between the first sealing ring 300 and the charging port cover plate 600, which is beneficial to extending the service life of the first sealing ring 300. The first sealing ring 300 is less likely to fail to seal, thereby improving the sealing performance of the switch device 1.

[0051] Furthermore, the radial sealing portion 310 is connected to the radially inner side of the axial sealing portion 320, and the radial sealing portion 310 abuts against and seals the outer peripheral surface of the keycap 200. That is, the radial sealing portion 310 can be fitted onto the outer periphery of the keycap 200; for example, the radial sealing portion 310 can be press-fitted with the outer peripheral surface of the keycap 200 to seal against it. In this way, the first sealing ring 300 can achieve a combination of radial sealing (between the radial sealing portion 310 and the outer peripheral surface of the keycap 200) and axial sealing (between the axial sealing portion 320 and the charging port cover plate 600), resulting in a better sealing effect and more effectively avoiding the sealing failure problems that easily occur with single radial or single axial sealing, thus significantly improving the sealing performance of the switching device 1.

[0052] Furthermore, the radial sealing portion 310 can deform along the axial direction of the first sealing ring 300 to provide an elastic force for the keycap 200 to slide away from the microswitch assembly 700. Specifically, when the keycap 200 is pressed downward along the axial direction, the radial sealing portion 310 can move with the keycap 200. At this time, the radial sealing portion 310 can be compressed and deformed, so that the first sealing ring 300 will not prevent the keycap 200 from moving downward, so that the microswitch assembly 700 can be pressed by the downward movement of the keycap 200. At the same time, the radial sealing portion 310 can generate an elastic force. When the user releases the keycap 200, the elastic force of the radial sealing portion 310 can drive the keycap 200 to move upward and reset. That is, the radial sealing portion 310 can assist the keycap 200 to rebound upward, thereby avoiding the phenomenon that the keycap 200 cannot rebound. The keycap 200 can perform more cycles of reciprocating pressing movements, and the service life of the switch device 1 is longer.

[0053] Thus, the switch device 1 according to the present utility model embodiment can not only improve the sealing effect between the keycap 200 and the fixing seat 100 and the charging port cover plate 600, but also ensure that the keycap 200 can reliably rebound, which is beneficial to improving the service life of the switch device 1.

[0054] In some specific embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the radial sealing portion 310 extends inward along the radial direction of the first sealing ring 300, and extends obliquely away from the micro switch assembly 700.

[0055] In other words, the radial sealing portion 310 gradually tilts upward along the radial inward of the first sealing ring 300. Thus, when the keycap 200 presses down on the micro switch assembly 700 along the axial direction of the fixing base 100, the radial sealing portion 310 deforms under the downward pressing force of the keycap 200. At this time, the radial sealing portion 310 can better generate an upward reset elastic force. In turn, the elastic force of the radial sealing portion 310 can be used to drive the keycap 200 to move away from the micro switch assembly 700. That is, the keycap 200 can be reset upward under the drive of the radial sealing portion 310, thereby avoiding the problem of the keycap 200 not being able to spring back.

[0056] In some specific embodiments of this utility model, such as Figure 4 As shown, along the axial direction of the first sealing ring 300, the thickness of the radial sealing portion 310 is less than the thickness of the axial sealing portion 320. This makes the radial sealing portion 310 more prone to deformation, allowing it to elastically deform when compressed by the keycap 200. This generates an elastic force that drives the keycap 200 to rebound reliably.

[0057] Furthermore, it is understood that after the upper side of the axial sealing part 320 abuts and seals with the charging port cover plate 600, the lower side of the axial sealing part 320 can abut with the fixed seat 100. That is, the fixed seat 100 and the charging port cover plate 600 can limit the axial sealing part 320 along the axial direction of the fixed seat 100. By setting a larger thickness for the axial sealing part 320, the structural strength of the axial sealing part 320 can be ensured, so that the axial sealing part 320 can be more stably abutted and fixed between the fixed seat 100 and the charging port cover plate 600. This can prevent the first sealing ring 300 from moving along the axial direction of the fixed seat 100 as a whole, effectively preventing excessive wear of the first sealing ring 300, thus preventing sealing failure of the first sealing ring 300 and extending the service life of the first sealing ring 300.

[0058] Furthermore, the radial sealing part 310 is connected to one end of the axial sealing part 320 near the micro switch assembly 700. In this way, when the upper side of the axial sealing part 320 abuts against the charging port cover plate 600 for sealing, the radial sealing part 310 is less likely to interfere with the position of the charging port cover plate 600. The structure is more reasonable and the assembly is more convenient.

[0059] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the radial sealing portion 310 extends in an annular shape along the circumference of the first sealing ring 300; and / or, the axial sealing portion 320 extends in an annular shape along the circumference of the first sealing ring 300.

[0060] For example, the radial sealing portion 310 may extend into an annular shape along the circumference of the first sealing ring 300, or the axial sealing portion 320 may extend into an annular shape along the circumference of the first sealing ring 300, or the radial sealing portion 310 may extend into an annular shape along the circumference of the first sealing ring 300, and the axial sealing portion 320 may extend into an annular shape along the circumference of the first sealing ring 300.

[0061] By configuring both the radial sealing portion 310 and the axial sealing portion 320 into a ring-shaped structure extending circumferentially along the first sealing ring 300, the sealing effect of the radial sealing portion 310 and the axial sealing portion 320 is improved. The radial sealing portion 310 can completely seal the circumference of the keycap 200, and the axial sealing portion 320 can completely seal the circumference of the charging port cover plate 600, further improving the overall sealing effect of the switching device 1.

[0062] In some specific embodiments of this utility model, the fixing seat 100 can be made of PC (Polycarbonate) and / or ABS (Acrylonitrile Butadiene Styrene Plastic) material, and the first sealing ring 300 can be made of TPE (Thermoplastic Elastomer). Specifically, the fixing seat 100 and the first sealing ring 300 can be processed and formed separately, and then the first sealing ring 300 is fitted onto the keycap 200. After the switch device 1 is assembled, the axial side of the first sealing ring 300 can be supported on the fixing seat 100. In this way, the first sealing ring 300 is not easy to move as a whole, and the axial sealing effect of the first sealing ring 300 can be better.

[0063] In some specific embodiments of this utility model, such as Figure 4 As shown, the outer peripheral surface of the keycap 200 is provided with a first sealing groove 210, which extends circumferentially along the keycap 200. At least a portion of the radial sealing portion 310 extends into the first sealing groove 210 and abuts against the bottom wall of the first sealing groove 210 for sealing. In this way, the sealing structure of the radial sealing portion 310 and the keycap 200 can form a clamp-type radial seal.

[0064] The radial sealing portion 310 can be interference-fitted with the bottom wall of the first sealing groove 210, and the opposite sides of the radial sealing portion 310 in the thickness direction can respectively stop against the upper and lower side walls of the first sealing groove 210. In this way, not only can the bottom wall of the first sealing groove 210 seal with the radial sealing portion 310, but the upper and lower side walls of the first sealing groove 210 can also hold the radial sealing portion 310, so that the radial sealing portion 310 can move with the keycap 200. This avoids friction and wear on the radial sealing portion 310 caused by the mutual movement between the radial sealing portion 310 and the keycap 200, and more effectively avoids the problem of sealing failure of the first sealing ring 300.

[0065] In some specific embodiments of this utility model, such as Figure 3 As shown, the switching device 1 also includes a second sealing ring 400.

[0066] The second sealing ring 400 is sleeved outside the fixed seat 100 and located between the charging port cover plate 600 and the fixed seat 100. The charging port cover plate 600 is provided with a sealing step 610, and the sealing step 610 abuts against one axial side of the second sealing ring 400 for sealing.

[0067] The second sealing ring 400 can be located near the side of the fixed seat 100 away from the keycap 200, that is, the second sealing ring 400 can be located near the lower side of the fixed seat 100, and the second sealing ring 400 extends in a ring along the circumference of the fixed seat 100. When the switch device 1 is installed on the charging port cover plate 600, the two axial sides of the second sealing ring 400 can respectively abut and seal with the fixed seat 100 and the sealing step 610. In this way, the second sealing ring 400 can seal the lower side of the fixed seat 100 and the charging port cover plate 600 along the axial direction to prevent water, dust and other impurities from entering the receiving cavity 110.

[0068] Furthermore, the second sealing ring 400 is located between the charging port cover plate 600 and the fixed seat 100, which can prevent the fixed seat 100 from directly contacting the charging port cover plate 600. The second sealing ring 400 can provide vibration damping and buffering, and can also prevent mutual wear between the fixed seat 100 and the charging port cover plate 600.

[0069] In some specific embodiments of this utility model, such as Figure 6 As shown, the outer peripheral surface of the fixed base 100 is provided with a second sealing groove 120. The second sealing groove 120 extends along the circumference of the fixed base 100. The second sealing ring 400 is disposed in the second sealing groove 120 and abuts against the bottom wall of the second sealing groove 120 for sealing.

[0070] The inner radial side of the second sealing ring 400 can extend into the second sealing groove 120, and the outer radial side of the second sealing ring 400 can be located outside the second sealing groove 120, so that the second sealing ring 400 can abut and seal with the sealing step 610.

[0071] By setting the second sealing groove 120, the upper and lower side walls of the second sealing groove 120 can abut against the second sealing ring 400, thereby preventing the second sealing ring 400 from moving axially along the fixed seat 100, which is beneficial to improving the sealing effect of the second sealing ring 400 on the lower side of the fixed seat 100 and the charging port cover plate 600.

[0072] In some specific embodiments of this utility model, such as Figure 3 and Figure 6 As shown, a sealing soft rubber layer 500 is provided in the receiving cavity 110, and the sealing soft rubber layer 500 is disposed between the micro switch assembly 700 and the keycap 200.

[0073] The sealing soft rubber layer 500 can be injection molded and filled within the receiving cavity 110, resulting in better consistency in product dimensions and performance. By setting the sealing soft rubber layer 500 between the micro switch assembly 700 and the keycap 200, the sealing soft rubber layer 500 can form a seal on the outside of the micro switch assembly 700 to protect it. Furthermore, the sealing soft rubber layer 500 can elastically deform, so when the user presses the keycap 200, the sealing soft rubber layer 500 will not prevent the keycap 200 from pressing the micro switch assembly 700, thus facilitating control of the micro switch assembly 700.

[0074] In addition, the sealing soft rubber layer 500 can also generate an elastic force to drive the keycap 200 to recover along the axial direction. That is, the sealing soft rubber layer 500 can be used to further increase the elastic force of the keycap 200 after it is pressed, so that the keycap 200 can reciprocate more smoothly along the axial direction, thereby ensuring the normal operation of the switch device 1.

[0075] Furthermore, the sealing soft rubber layer 500 can also buffer and dampen vibration, which can prevent the keycap 200 from having too much impact on the micro switch assembly 700, thereby preventing damage to the keycap 200 and the micro switch assembly 700 after repeated impacts, which is beneficial to improving the service life of the micro switch assembly 700, and thus extending the service life of the switching device 1.

[0076] In some specific embodiments of this utility model, such as Figure 3 As shown, the micro switch assembly 700 includes a circuit board 710, a micro switch 720, a plug 730, and a potting compound layer 740.

[0077] The circuit board 710 is disposed in the receiving cavity 110, the micro switch 720 is connected to the side of the circuit board 710 facing the keycap 200, the plug 730 is supported on the side of the circuit board 710 facing away from the micro switch 720, and the potting compound layer 740 is disposed on the side of the plug 730 facing away from the micro switch 720 to seal the bottom of the receiving cavity 110.
