Due to its convenience, it has become a standard feature of most car seat adjustment switches, and with the development of the automotive industry, it will have a great prospect of application in the future.

[0003] Currently, the car seat adjustment switch mainly consists of a housing, a horizontal button, and a switch module. The horizontal button is movably mounted on the housing. Specifically, a slider is slidably mounted on the housing, and the horizontal button is mounted on the slider and thus movably mounted on the housing via the slider. The switch module is fixedly mounted on the housing and connected to the horizontal button. By pushing or toggling the horizontal button, the switch module can be triggered, thereby realizing the interactive control function.

[0004] However, the current horizontal buttons have tactile defects when pressed. For example, the slider is prone to jamming during long-term use, which affects the adjustment operation. There is still a lack of a solution that can effectively improve the smoothness of operation in the existing technology, so it needs to be improved.

[0044] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0046] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0047] The following is in conjunction with the appendix Figure 1-5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0048] Example 1:

[0049] Please refer to Figure 1 and Figure 2 This utility model provides a slider-plate mounting structure, including a housing 1, a slider 2, and a pressure plate 3.

[0050] The outer shell 1 has a through-hole 11, and the slider 2 passes through the through-hole 11. The slider 2 is used for mounting the horizontal button 4. Specifically, the horizontal button 4 is mounted on the end of the slider 2 that passes through the outer shell 1, and the size of the slider 2 is smaller than the opening size of the through-hole 11. This allows the slider 2 to move within the through-hole 11 to avoid collision interference between the outer shell 1 and the slider 2.

[0051] In addition, the pressure plate 3 is fixedly installed inside the outer shell 1. When the pressure plate 3 is fixed to the outer shell 1, an assembly space is formed between the pressure plate 3 and the outer shell 1. At this time, the slider 2 is located in the assembly space. Furthermore, the pressure plate 3 has a first smooth plane 31 facing the location of the slider 2. The inner side of the outer shell 1 has a second smooth plane 12, which is opposite to the slider 2. The first smooth plane 31 and the second smooth plane 12 are opposite to each other and parallel to each other. The opposite sides of the slider 2 slide and abut against the first smooth plane 31 and the second smooth plane 12 respectively.

[0052] By adopting the above-mentioned configuration, on the one hand, the pressure plate 3 can limit the slider 2, allowing it to slide smoothly within the assembly space and preventing it from easily coming loose. On the other hand, the parallel first smooth plane 31 and the second smooth plane 12 form a flat assembly space. When the slider 2 slides within the assembly space, it can be guided by the first smooth plane 31 and the second smooth plane 12, making it less prone to shaking or vertical floating, thus improving the flatness of the structure. Furthermore, the first smooth plane 31 and the second smooth plane 12 can further provide smooth guidance for the slider 2, making the slider 2 move more smoothly and silkily, and the operation of the horizontal button 4 is less prone to jamming or stopping.

[0053] Optionally, the surface roughness Ra of the first smooth plane 31 is ≤ 0.3 μm. It is understood that when the surface roughness Ra is less than or equal to 0.3 μm, the first smooth plane 31 can achieve a smoothness that ensures the slider 2 is smoothly guided when it comes into contact with the first smooth plane 31.

[0054] For example, the surface roughness Ra of the first smooth plane 31 can specifically be 0.01μm, 0.02μm, 0.03μm, 0.04μm, 0.05μm, 0.06μm, 0.07μm, 0.08μm, 0.09μm, 0.10μm, 0.11μm, 0.12μm, 0.13μm, 0.14μm, 0.15μm, 0.16μm, 0.17μm, 0.18μm, 0.19μm, 0.20μm, etc. The surface roughness values ​​of the first smooth plane 31 can be selected from 0.21μm, 0.22μm, 0.23μm, 0.24μm, 0.25μm, 0.26μm, 0.27μm, 0.28μm, 0.29μm, or 0.30μm. The specific roughness value of the first smooth plane 31 can be adjusted according to actual needs or production costs, and no specific limitation is made here. In another embodiment, the surface roughness Ra of the first smooth plane 31 can be selected between any two of the above parameter values.

[0055] Optionally, the surface roughness Ra of the second smooth plane 12 is ≤ 0.3 μm. It is understood that when the surface roughness Ra is less than or equal to 0.3 μm, the second smooth plane 12 can achieve a smoothness that ensures smooth guidance when the slider 2 comes into contact with the second smooth plane 12.

[0056] For example, the surface roughness Ra of the second smooth plane 12 can specifically be 0.01μm, 0.02μm, 0.03μm, 0.04μm, 0.05μm, 0.06μm, 0.07μm, 0.08μm, 0.09μm, 0.10μm, 0.11μm, 0.12μm, 0.13μm, 0.14μm, 0.15μm, 0.16μm, 0.17μm, 0.18μm, 0.19μm, 0.20μm, etc. The surface roughness values ​​of the second smooth plane 12 can be selected from 0.21μm, 0.22μm, 0.23μm, 0.24μm, 0.25μm, 0.26μm, 0.27μm, 0.28μm, 0.29μm, or 0.30μm. The specific roughness value of the second smooth plane 12 can be adjusted according to actual needs or production costs, and no specific limitation is made here. In another embodiment, the surface roughness Ra of the second smooth plane 12 can be selected between any two of the above parameter values.

[0057] Furthermore, continue to refer to Figure 1 and Figure 2In order to enable the pressure plate 3 to be fixedly connected to the outer shell 1, in one embodiment of the present application, the edge of the pressure plate 3 is provided with a lug 32, and the lug 32 is provided with a mounting hole 321 that passes through both sides. A threaded fastener 33 is provided through the mounting hole 321. Usually, the threaded fastener 33 is a screw or bolt. At the same time, the outer shell 1 has a threaded hole that is threadedly connected to the threaded fastener 33. The threaded hole and the mounting hole 321 are coaxially arranged. In this case, by installing the threaded fastener 33 in the threaded hole, the pressure plate 3 and the outer shell 1 can be fixedly connected. The assembly process is convenient, quick and firm.

[0058] In another embodiment, the pressure plate 3 and the outer shell 1 can also be fixed to each other by setting a snap-fit ​​structure. In this case, no matter what specific connection method is used between the pressure plate 3 and the outer shell 1, it should be included in the explanation of the equivalent alternative means in this solution.

[0059] Furthermore, there are multiple sets of mutually cooperating lugs 32 and threaded fasteners 33, with multiple lugs 32 evenly arranged along the circumference of the pressure plate 3. Correspondingly, the number and distribution of threaded holes on the outer shell 1 are adapted to the arrangement of lugs 32 and threaded fasteners 33.

[0060] Here, by setting multiple sets of lugs 32 and threaded fasteners 33, the pressure plate 3 can be reinforced in multiple directions in the circumferential direction, the pressure plate 3 is not easy to shift, and it is beneficial to further improve the structural flatness of the pressure plate 3.

[0061] For example, the specific number of lugs 32 and threaded fasteners 33 can be two, three, four, five, six, seven, eight, etc. The specific number and arrangement can be adjusted according to actual needs, and are not limited here. In this embodiment, seven groups are selected as an example.

[0062] Furthermore, referring to Figure 3 In the embodiments of this application, the slider 2 includes a base plate 21 and a button assembly part 22. The base plate 21 has a flat plate structure and has two opposing and parallel abutting surfaces 211. The base plate 21 is located in the assembly space. The two abutting surfaces 211 of the base plate 21 slide and abut against the first smooth surface 31 and the second smooth surface 12, respectively. At this time, the two abutting surfaces 211 can form a flat sliding mating surface to ensure that the slider 2 can slide stably.

[0063] Meanwhile, the button assembly part 22 is located on one of the abutting planes 211. Specifically, the button assembly part 22 is protruding and integrally connected with the base plate 21. The button assembly part 22 is located on the abutting plane 211 facing away from the pressure plate 3. At this time, the button assembly part 22 passes through the mounting port 11 for the horizontal button 4 to be assembled.

[0064] Based on the above settings, the button assembly 22 can support the horizontal button 4 and raise the horizontal button 4 to a certain height relative to the outer shell 1. On the one hand, it prevents the horizontal button 4 from touching the outer shell 1 and maintains smooth operation. On the other hand, it makes it easier for users to touch the horizontal button 4, thus optimizing and improving the user experience.

[0065] Furthermore, referring to Figure 3 and Figure 4 The slider pressure plate mounting structure provided in this application also includes a horizontal button 4, which is detachably connected to the button assembly part 22. By detachably connecting the horizontal button 4 to the button assembly part 22, the assembly convenience of the switch assembly can be improved and the assembly difficulty of the switch assembly can be reduced.

[0066] In the embodiments of this application, in order to achieve a detachable connection between the horizontal button 4 and the button assembly part 22, the horizontal button 4 is provided with a first fastening position 6, and at the same time, the button assembly part 22 is provided with a second fastening position 5 that is movably fastened to the first fastening position 6.

[0067] By fastening the second fastener 5 into the first fastener 6, a detachable connection can be achieved between the horizontal button 4 and the button assembly part 22. The assembly process is convenient and quick, which can effectively reduce labor costs and improve assembly efficiency.

[0068] It is understood that in one embodiment, the first snap-fit ​​position 6 is a snap-fit ​​recess and the second snap-fit ​​position 5 is a snap-fit ​​protrusion. With the cooperation of the snap-fit ​​recess and the snap-fit ​​protrusion, a quick snap-fit ​​effect can be achieved. Correspondingly, in another embodiment, the first snap-fit ​​position 6 is a snap-fit ​​protrusion and the second snap-fit ​​position 5 is a snap-fit ​​recess, which can also achieve a quick snap-fit ​​effect. Regardless of the specific snap-fit ​​structure adopted by the first snap-fit ​​position 6 and the second snap-fit ​​position 5, they are all included in the scope of this solution and are not specifically limited here.

[0069] Furthermore, to improve the assembly stability of the horizontal button 4 and reduce shaking, the horizontal button 4 is provided with a first positioning rib 7, which is usually integrally connected with the horizontal button 4, and the first positioning rib 7 is provided with a positioning notch 71. At the same time, the button assembly part 22 is provided with a second positioning rib 8, which corresponds to the positioning notch 71. The second positioning rib 8 can be inserted and engaged with the positioning notch 71. When the horizontal button 4 is assembled into the button assembly part 22, the first positioning rib 7 is inserted into the positioning notch 71, which strengthens the positioning of the horizontal button 4, making the assembly of the horizontal button 4 more stable and less prone to shaking, thus improving the operating feel.

[0070] The slider pressure plate mounting structure provided in this embodiment has the following beneficial effects:

[0071] 1. Under the guidance of the first smooth plane 31 and the second smooth plane 12, the displacement flatness of the slider 2 is optimized and improved, the movement is smooth and not easy to jam, and the operation feel of the switch is significantly improved.

[0072] 2. The pressure plate 3 is assembled stably and flat, which can provide a good sliding guide effect for the slider 2;

[0073] 3. The horizontal button 4 and the slider 2 are easy to assemble, and the assembly is efficient and simple.

The switch module includes components such as a circuit board and a rocker switch. The specific structure of the switch module is prior art and will not be described in detail here.

[0077] The switch module is located in the housing 1 and connected to the slider 2. By toggling the horizontal button 4, the rocker switch can be triggered, thereby realizing the control function.

[0078] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
