Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a switch assembly and a vehicle using the switch assembly. Background Technology
[0002] Vehicles typically have pull-type or lever-type mechanical switches to adjust the windows and air conditioning direction.
[0003] In related technologies, both of the aforementioned mechanical switches include a housing and a push rod, with the housing having a sliding hole through which the push rod passes. After the switch button is pressed, the push rod moves downwards, causing the contacts on the conductive rubber trigger circuit board located below the push rod to convert into an electrical signal output, thus achieving the corresponding function. When the button is released, the elastic force of the conductive rubber causes the push rod to return to its original position.
[0004] However, in the aforementioned mechanical switches, particles such as sand can enter the gap between the push rod and the sliding hole. If the accumulation of particles is excessive, it can cause blockage. Consequently, jamming can occur during the push rod's reset process, affecting the normal operation of the mechanical switch and consequently impacting the realization of its functions, thus reducing the overall performance of the vehicle. Utility Model Content
[0005] This application provides a switch assembly and a vehicle that can, to a certain extent, avoid jamming during the push rod reset process, thereby improving the performance of the switch assembly and facilitating the realization of the corresponding functions. This also results in better performance of the vehicle provided in this application.
[0006] On one hand, this application provides a switch assembly, including a push rod, a housing, and a stop structure; the push rod includes a rod body; the housing has a sliding hole through which the rod body passes, and a gap is formed between the side wall of the rod body and the wall of the sliding hole; the stop structure is disposed within the gap.
[0007] As an optional implementation, the stop structure includes a stop protrusion disposed on the wall of the sliding hole; the stop protrusion protrudes toward the rod body and abuts against the rod body.
[0008] As an optional implementation, the sliding hole has multiple stop protrusions on its wall; the multiple stop protrusions are evenly distributed along the circumference of the sliding hole, and a hollow portion is formed between two adjacent stop protrusions.
[0009] As an optional implementation, the dimension of the cutout portion in the radial direction of the sliding hole is 0.5 mm.
[0010] As an optional implementation, the top rod also includes a cover portion connected to the rod body and located above the gap; the cover portion has a cover surface facing the gap, and the orthographic projection area of the gap on the cover surface falls within the cover surface.
[0011] As an optional implementation, the outer shell includes a shell body and a protrusion connected to the upper end of the shell body; the sliding hole includes a first hole segment and a second hole segment that communicate with each other, the first hole segment being formed on the protrusion and the second hole segment being formed on the shell body; the covering part includes a covering plate and a flange, the covering plate being connected to the rod body, and the bottom surface of the covering plate forming a covering surface; the flange being connected to the outer edge of the covering plate and extending downward, and the flange slidingly engaging with the protrusion.
[0012] As an optional implementation, the rod body includes a first rod segment, a second rod segment, and a third rod segment connected together; the first rod segment is located above the cover plate, the second rod segment is connected to the cover plate, the third rod segment is located below the cover plate, and the third rod segment is slidably engaged with the sliding hole.
[0013] As an alternative implementation, the push rod is a one-piece molded part.
[0014] As an optional implementation, the switch assembly provided in this application further includes an elastic conductive module, with the bottom end of the rod body pressing against the elastic conductive module.
[0015] On the other hand, this application provides a vehicle including the aforementioned switch assembly.
[0016] In the switch assembly and vehicle provided in this application, a stop structure is provided in the gap formed between the rod body of the push rod and the sliding hole of the housing.
[0017] Thus, by setting up a stop structure, external particles, such as sand, may be blocked when they move to the gap, thereby reducing the number of particles entering the gap.
[0018] Thus, compared to mechanical switches in related technologies, particles such as sand are less likely to accumulate in the gap of the switch assembly provided in this application embodiment. This, to a certain extent, prevents the push rod from getting stuck during the reset process, allowing the switch assembly provided in this application embodiment to maintain better performance.

[0035] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0037] Vehicles typically have pull-type or lever-type mechanical switches to adjust the windows and air conditioning direction.
[0038] In related technologies, both of the aforementioned mechanical switches include a housing and a push rod, with a sliding hole on the housing for the push rod to pass through. After the switch button is pressed, the push rod moves downwards, causing the contacts on the conductive rubber trigger circuit board located below the push rod to convert into an electrical signal output, thus achieving the corresponding function. When the button is released, the elastic force of the conductive rubber causes the push rod to return to its original position.
[0039] However, in the aforementioned mechanical switches, particles such as sand can enter the gap between the push rod and the sliding hole. If the accumulation of particles is excessive, it can cause blockage. Consequently, jamming can occur during the push rod's reset process, affecting the normal operation of the mechanical switch and consequently impacting the realization of its functions, thus reducing the overall performance of the vehicle.
[0040] Therefore, this application provides a switch assembly and a vehicle. By providing a stop structure within the gap, the amount of particles entering the gap can be reduced, thereby preventing the accumulation of particles, such as sand, within the gap to a certain extent. This also helps prevent the push rod from jamming during reset, ensuring the normal operation of the switch assembly provided in this application. Furthermore, it improves the performance of the vehicle provided in this application.
[0041] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.
[0042] Please see Figures 1 to 2 , Figure 1 This is a three-dimensional structural diagram of the switch assembly provided in an embodiment of this application. Figure 2This is an exploded view of a switch assembly provided in an embodiment of this application. As shown in the figure, this embodiment provides a switch assembly 100, including a housing 1 and a push rod 2. The push rod 2 and the housing 1 are slidably engaged in the vertical direction (the height direction of the housing 1). The push rod 2 includes a rod body 21. The housing 1 has a sliding hole 11 through which the rod body 21 passes. A gap 9 is formed between the side wall of the rod body 21 and the wall of the sliding hole 11.
[0043] The top of the outer casing 1 is connected to a panel 3 and a decorative strip 4 surrounding the panel 3. At least one button 5 is connected to the panel 3, and the button 5 is connected to a mating hole 31 on the panel 3. The bottom of the outer casing 1 is sequentially connected to an elastic conductive module, a printed circuit board (PCB) 7, and a base 8. The elastic conductive module can be conductive rubber 6, and the bottom end of the rod body 21 presses against the conductive rubber 6.
[0044] When the switch assembly 100 is used, button 5 presses down on the push rod 2, pushing the conductive rubber 6 to the contact point on the PCB board 7, making the contact conductive and realizing the operation response of button 5. When button 5 is released, the self-rebound force of the conductive rubber 6 pushes the push rod 2 back to the initial position, and the contact is broken.
[0045] It should be noted that the above-mentioned up and down directions are different from, for example... Figure 1 The top and bottom directions are consistent.
[0046] In certain driving environments, such as in the desert, when the driver opens the doors and windows or opens the door after parking, sand often blows into the driver's cabin and into the door and window switches and the sub-panel switches. The sand can also enter the switches through gaps.
[0047] Specifically, in the switch assembly 100, since the button 5 is a moving part, the matching gap 9 at the mating hole 31 causes sand to enter the interior of the switch assembly 100 from the outside.
[0048] In the desert, sand is often fine sand with a diameter of 0.0625 mm or more and less than 2 mm or less. The gap 9 is often set to 0.05 mm on one side. Since the matching area between the top rod 2 and the outer shell 1 is large, fine sand with a diameter of 0.1 mm or more and less than 0.2 mm or less can accumulate at the gap 9.
[0049] At this time, when the button 5 is operated, the push rod 2 moves downward and fills the gap 9 with the sand that was originally piled up, and causes the outer shell 1 to deform. The resistance experienced by the push rod 2 will be greater than the rebound force of the conductive rubber 6, thus causing the push rod 2 to get stuck.
[0050] Therefore, please combine Figures 3 to 5 , Figure 3 This is a schematic diagram of the planar structure of the switching assembly provided in an embodiment of this application. Figure 4 for Figure 3 Cross-sectional view along the AA direction. Figure 5 for Figure 4 A magnified view of the partial structure at point B. To avoid the aforementioned jamming phenomenon to a certain extent, the switch assembly 100 provided in this embodiment also includes a stop structure 10, which is disposed within the gap 9.
[0051] Thus, by setting the stop structure 10, external particles, such as sand, may be blocked when they move to the gap 9, thereby reducing the number of particles entering the gap 9. Therefore, compared with mechanical switches in related technologies, particles such as sand are less likely to accumulate in the gap 9 in the switch assembly provided in this embodiment. This, to a certain extent, prevents the push rod 2 from jamming during the reset process, allowing the switch assembly 100 provided in this embodiment to maintain good performance.
[0052] Please continue to combine Figure 6 and Figure 7 , Figure 6 This is a three-dimensional structural diagram of the housing in the switch assembly provided in the embodiments of this application. Figure 7 for Figure 6 A magnified view of the partial structure at point C. In some specific embodiments, the stop structure 10 includes a stop protrusion 101, which is disposed on the wall of the sliding hole 11; the stop protrusion 101 protrudes toward the rod body 21 and abuts against the rod body 21.
[0053] Thus, by having the stop protrusion 101 abut against the rod body 21, there is no gap between the stop protrusion 101 and the side of the rod body 21. On the one hand, by having the stop protrusion 101 occupy part of the gap 9, it prevents particles from entering. On the other hand, by limiting the position between the stop protrusion 101 and the outer side of the rod body 21, it is difficult for particles to enter between the stop protrusion 101 and the rod body 21. In this way, the number of particles entering the gap 9 can be further reduced, thereby preventing the push rod 2 from getting stuck during the reset process to a certain extent.
[0054] Understandably, the more stop protrusions 101 there are, the better the stopping effect of the stop structure 10 will be.
[0055] Therefore, in this specific embodiment, a plurality of stop protrusions 101 are provided on the wall of the sliding hole 11. The plurality of stop protrusions 101 are evenly distributed circumferentially along the sliding hole 11, and a hollow portion 20 is formed between two adjacent stop protrusions 101. In this way, by providing a plurality of stop protrusions 101, the stopping effect of the stop structure 10 on particles can be improved, thereby further reducing the number of particles entering the gap 9.
[0056] The shape of the stop protrusion 101 can be such that, in the axial direction of the sliding hole 11, the size of the stop protrusion 101 is the same as the axial dimension of the sliding hole 11. The cross-sectional shape of the stop protrusion 101 can be semi-circular. Of course, in some other embodiments, the size of the stop protrusion 101 in the axial direction of the sliding hole 11 can be smaller than the axial dimension of the sliding hole 11. The cross-sectional shape of the stop protrusion 101 can also be other shapes. Here, no specific limitations are placed on the size and shape of the stop protrusion 101.
[0057] If the size of the perforated portion 20 in the radial direction of the sliding hole 11 is too large or too small, more particles will enter the perforated portion 20, easily causing blockage. Therefore, in the specific implementation of this embodiment, the radial dimension of the perforated portion 20 is limited. Specifically, the radial dimension of the perforated portion 20 in the sliding hole 11 is 0.5 mm.
[0058] In this way, when the diameter of the particles is less than 0.5 mm, they will flow downwards after entering the hollow section 20. When the diameter of the particles is greater than 0.5 mm, they will not flow into the hollow section 20. Thus, by limiting the size of the hollow section 20, the number of particles entering the hollow section 20 is reduced, further reducing the risk of jamming of the push rod 2 during the reset process.
[0059] Please continue to combine Figures 8 to 10 , Figure 8 for Figure 3 A schematic diagram of the planar structure from another perspective. Figure 9 for Figure 8 Cross-sectional view along the DD direction. Figure 10 for Figure 9 A magnified view of the partial structure at point E. As for the structure of the outer shell 1, it can be that the outer shell 1 includes a shell body 12 and a protrusion 13 connected to the upper end of the shell body 12; the sliding hole 11 includes a first hole segment 111 and a second hole segment 112 that are connected, the first hole segment 111 is formed on the protrusion 13, and the second hole segment 112 is formed on the shell body 12.
[0060] Please continue to combine Figure 11 and Figure 12 , Figure 11This is a three-dimensional structural diagram of the push rod in the switch assembly provided in the embodiments of this application. Figure 12 for Figure 11 A three-dimensional structural diagram from another perspective. Of course, if the entry of particles can be directly blocked above gap 9, the risk of jamming of push rod 2 during the reset process will be further reduced.
[0061] Thus, in some optional embodiments, the top rod 2 further includes a covering portion 22, which is connected to the rod body 21 and is located above the gap 9. The covering portion 22 has a covering surface 221 facing the gap 9, and the orthographic projection area of the gap 9 on the covering surface 221 falls within the covering surface 221. In this way, particles located above the gap 9 are less likely to enter the gap 9, thereby further reducing the number of particles entering the gap 9.
[0062] Of course, if particles can be prevented from entering the gap 9 from the side of the covering part 22, the number of particles entering the gap 9 can be greatly reduced. In this way, the stick 2 can be prevented from getting stuck during the reset process to a large extent.
[0063] Based on this, in some embodiments, the covering portion 22 includes a covering plate 222 and a flange 223. The covering plate 222 is connected to the rod body 21, and the bottom surface of the covering plate 222 forms a covering surface 221. The flange 223 is connected to the outer edge of the covering plate 222 and extends downward, and the flange 223 slides in engagement with the protrusion 13. In this way, by providing the flange 223, particles located on the side of the protrusion 13 can be prevented from entering the gap 9, thereby largely avoiding jamming of the push rod 2 during the reset process.
[0064] Regarding the specific shape of the rod body 21, it can be that the rod body 21 includes a first rod segment 211, a second rod segment 212, and a third rod segment 213 connected together. The first rod segment 211 is located above the cover plate 222, the second rod segment 212 is connected to the cover plate 222, and the third rod segment 213 is located below the cover plate 222, and the third rod segment 213 is slidably engaged with the sliding hole 11. In this way, the first rod segment 211 is protruding, which makes it easy for the top of the rod body 21 to be connected with the button 5, so that the switch assembly 100 provided in this embodiment has high stability in use.
[0065] In some embodiments, the ejector pin 2 is a plastic part, and the ejector pin 2 is a one-piece molded part. This can improve the manufacturing efficiency of the ejector pin 2. Here, there are no specific limitations on the molding method of the ejector pin 2.
[0066] When assembling the lifting rod 2 in this embodiment, a pressing method from top to bottom is adopted. When the bottom end of the lifting rod 2, that is, the bottom end of the third rod segment 213, presses against the pressure head 30 located at the top of the conductive rubber 6, it indicates that the assembly of the lifting rod 2 is complete.
[0067] This embodiment also provides a vehicle, including a body and the aforementioned switch assembly 100, the switch assembly 100 being fixed to the vehicle body. The structure of the switch assembly 100 has been described in detail in the above embodiments and will not be repeated here.
[0068] It should be noted that the vehicle provided in this embodiment should also include other modules or components that enable the vehicle to operate normally. Here, the other modules or components included in the vehicle provided in this embodiment will not be described one by one.
[0069] The vehicle provided in this embodiment has better performance by adopting the switch assembly 100 of the above-described embodiment.
[0070] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
