Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of seat adjustment switches, and in particular to a seat adjustment button mounting structure and switch assembly to prevent functional failure. Background Technology
[0002] Seat adjustment switches are control devices used to adjust the position, angle, and function of car seats. They are usually found in models equipped with electric seats. With the development of automotive technology, more and more seats are equipped with car seat adjustment switches, and they have great application prospects in the future.
[0003] Typically, a car seat adjustment switch mainly consists of three components: a switch module, a housing, and a button. The switch module is fixedly installed on the housing, while the button is movably mounted on the housing. The button is connected to the port of the switch module. By toggling the button, the port of the switch module can be triggered, thereby realizing the command control function.
[0004] As consumers' demands for car seat adjustment switches become more diverse, some buttons undergo full electroplating to enhance their overall quality; however, common buttons are usually made of plastic and have a U-shaped elastic buckle structure. The U-shaped elastic buckle is deformed by compression and then springs back to achieve the purpose of fixing it to the outer shell.
[0005] However, during the electroplating process of the button, the U-shaped elastic latch function is prone to failure due to local stress concentration, high-temperature softening, and differences in thermal expansion and contraction. Therefore, there is still a lack of a solution in the existing technology that can avoid the failure of the latch function caused by electroplating, so improvement is needed.
[0006] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content
[0007] This utility model provides a seat adjustment button mounting structure and switch assembly to prevent functional failure, thereby solving the problem of button snap-fit failure caused by electroplating in the prior art.
[0008] To achieve the above objectives, in a first aspect, this utility model provides a seat adjustment button mounting structure to prevent functional failure, employing the following technical solution:
[0009] A seat adjustment button mounting structure to prevent functional failure includes:
[0010] Button body;
[0011] The buckle includes a column portion and a snap-fit portion. One end of the column portion is connected to the button body, and the snap-fit portion is located at the other end of the column portion. The outer periphery of the snap-fit portion protrudes from the column portion.
[0012] The housing is provided with a plug-in channel that engages with the snap-fit, and the opening edge of the plug-in channel has an elastic fastening element that engages with the snap-fit portion.
[0013] Preferably, the outer edge contour of the latching portion is circular or polygonal, and the opening contour of the insertion channel is adapted to the outer edge contour of the latching portion.
[0014] Preferably, the front end of the snap-fit portion has a chamfer.
[0015] Preferably, the column portion includes a first segment, a second segment, and a third segment that are connected sequentially from the root to the end and whose outer diameters decrease sequentially. The surfaces of the first segment and the third segment are flat surfaces, and the surface of the second segment is an inclined surface.
[0016] Preferably, the inner wall of the elastic fastener is inclined and forms an inlet angle.
[0017] Preferably, the inclination angle is 2°-15°.
[0018] Preferably, the outer shell is provided with a hollow column, the interior of which forms the insertion and removal channel, and the protrusion height of the hollow column is 8mm-15mm.
[0019] Preferably, there are multiple elastic fasteners, which are arranged at intervals along the circumferential opening of the insertion / removal channel.
[0020] Preferably, there are two elastic fasteners, which are arranged opposite to each other.
[0021] Secondly, this utility model provides a switch assembly with the following technical solution:
[0022] A switch assembly including the seat adjustment button mounting structure for preventing functional failure as described above.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] This utility model provides a seat adjustment button mounting structure to prevent functional failure. To avoid the problem of the buckle becoming brittle and cracking due to electroplating, which would lead to buckle malfunction, this solution adopts a buckle structure composed of a column and a snap-fit part. By inserting the buckle into the insertion channel and fastening the snap-fit part with the elastic fastener on the outer shell, the button body is assembled. The process is convenient and quick. Since the buckle structure composed of the column and the snap-fit part does not require slotting, the buckle can avoid forming a conventional U-shaped structure. During electroplating, a relatively uniform electroplating layer can be obtained, reducing stress concentration and meeting normal installation requirements. The problem of buckle malfunction caused by electroplating is thus solved.

[0041] 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.
[0042] 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.
[0043] 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.
[0044] The following is in conjunction with the appendix Figure 1-6 The technical solution of this utility model will be further illustrated through specific implementation methods.
[0045] Example 1:
[0046] Please refer to Figure 1 This utility model provides a seat adjustment button mounting structure to prevent functional failure, which solves the problem that conventional U-shaped buckles 2 are prone to functional failure during electroplating. The button mounting structure specifically includes: button body 1, buckle 2 and outer shell 3.
[0047] The button body 1 is usually made of plastic, with a smooth arc-shaped surface on one side and an inwardly recessed surface on the other side to form a shell structure. Depending on the actual needs, it can be a long strip or a circular outline. In this embodiment, a long strip outline is used as an example. It is understood that the specific outline and shape of the button body 1 are not limited here. Regardless of the structure it adopts, it should be included in the interpretation of the button body 1.
[0048] Meanwhile, the clip 2 is located at the button body 1. Typically, the clip 2 and the button body 1 are made of the same material, such as plastic. During manufacturing, they are integrally molded to ensure good connection stability. However, during electroplating, the button body 1 and the clip 2 need to be electroplated together to ensure the consistency of the plating layer. In this process, the button body 1 and the clip 2 undergo a series of operations such as applying electroplating solution, heating, and electrophoresis. This can easily lead to the clip 2 being affected by factors such as localized stress concentration, high-temperature softening, differences in expansion coefficients, chemical reactions, and additives, resulting in embrittlement or cracking, and ultimately, clip 2 failure.
[0049] Based on this, refer to Figure 1 and combined Figure 2 In the solution provided in this embodiment, the buckle 2 includes a column part 21 and a snap-fit part 22. One end of the column part 21 is connected to the button body 1, and the snap-fit part 22 is provided at the other end of the column part 21. The outer periphery of the snap-fit part 22 protrudes from the column part 21, which is equivalent to forming a buckle 2 structure similar to a mushroom head. This structure has a continuous and tight surface. Compared with the conventional buckle 2, it does not have a slotted feature. This makes it consistent in its expansion and contraction under heating and cooling conditions during the electroplating process, and it is not easy to generate local stress. Moreover, it can form an electroplating layer of uniform thickness on its surface, which greatly reduces the adverse effects it suffers during the electroplating process and reduces the embrittlement of the buckle 2.
[0050] At the same time, refer to Figure 3 The aforementioned buckle 2 is mainly assembled with the outer shell 3. The outer shell 3 is provided with a plug-in channel 31 that engages with the buckle 2. The opening edge of the plug-in channel 31 has an elastic fastening member 4 that is movably engaged with the snap-fit part 22. In this embodiment, the elastic fastening member 4 is integrally connected with the outer shell 3. Under the action of the elastic snap-fit, the button body 1 can be quickly installed. It can be understood that since the outer shell 3 does not need to be electroplated, the elastic fastening member 4 is not affected by embrittlement when placed on the outer shell 3, and the assembly stability between the buckle 2 and the outer shell 3 is significantly improved.
[0051] Optionally, the elastic fastener 4 can be a spring sheet structure or an elastic arm structure. Any shape that can achieve elastic fastening can be used. No specific structure of the elastic fastener 4 is limited here. Regardless of the specific structure of the elastic fastener 4, it should be included in the scope of this interpretation of the elastic fastener 4.
[0052] Therefore, by adopting the above solution, it is possible to effectively prevent the buckle 2 from deforming during assembly, reduce the impact of the electroplating process on the buckle 2, reduce the possibility of buckle 2 failure, and thus improve production efficiency and product quality.
[0053] Furthermore, referring to Figure 4 The column portion 21 includes a first segment 211, a second segment 212, and a third segment 213 that are connected sequentially from the root to the end and whose outer diameters are successively reduced. The surfaces of the first segment 211 and the third segment 213 are flat surfaces, while the surface of the second segment 212 is an inclined surface.
[0054] By adopting the above method, the first segment 211, the second segment 212 and the third segment 213 are equivalent to forming a stepped mating surface on the outside of the column part 21. The first segment 211 and 213, which are flat, can achieve multi-point mating with the insertion channel 31 in both the upper and lower directions, so that the assembly is tight and not easy to shake. In addition, the inclined second segment 212 can form a certain draft angle, so that the buckle 2 is easy to demold during the injection molding process.
[0055] Optionally, the outer edge contour of the latching part 22 is circular or polygonal, and the opening contour of the insertion channel 31 is adapted to the outer edge contour of the latching part 22. Based on this arrangement, when the latching part 22 is circular, the opening of the insertion channel is also set to be circular, which makes it easier to insert the buckle 2 into the insertion channel from multiple directions, making assembly more convenient.
[0056] When the latching part 22 is set as a polygon, such as a triangle, rectangle or hexagon, it can play a certain foolproof role between the buckle 2 and the outer shell 3, thereby improving the assembly accuracy of the button body 1. It is understood that the specific outline of the latching part 22 can be adjusted according to actual needs. Here, the specific outline of the latching part 22 is not limited. In this embodiment, the latching part 22 adopts a circular outer edge outline as an example. Correspondingly, the opening outline of the insertion channel 31 is also circular.
[0057] Furthermore, the front end of the snap-fit part 22 is provided with a chamfer 221. It is understood that the chamfer 221 can be a rounded corner or a beveled corner. By setting the chamfer structure, the snap-fit 2 can be guided when it is inserted into the insertion channel, and the convenience of assembly is improved. The specific shape of the chamfer 221 is not limited here. As long as a chamfer structure is used, it should be included in the scope of this solution.
[0058] Furthermore, continue to refer to Figure 3 To make the buckle 2 more smoothly engage with the elastic fastener 4, the inner wall of the elastic fastener 4 is inclined and forms an introductory angle. At this time, the inclined introductory angle can guide the buckle 2, so that the buckle 2 can be accurately engaged with the elastic fastener 4. In addition, by setting the interior of the insertion channel 31 to an inclined structure, a certain draft angle can also be formed to facilitate the smooth demolding of the outer shell 3 during production. Furthermore, the introductory angle can also abut against the outer surface of the buckle 2. When the buckle 2 is engaged with the end face of the elastic fastener 4, it forms an inverted triangular structure, generating tension and making the engagement more secure.
[0059] Optionally, the inlet angle tilt degree is 2°-15°. Here, the inlet angle is defined as α, such as... Figure 3 As shown, when the inclination angle of the inlet is less than 2°, it may cause difficulty in demolding the housing 3 and the buckle 2 may not be smooth when inserted. When the inclination angle of the inlet is greater than 15°, the overall size of the housing 3 will become larger, which does not meet the requirements of the compact design of the structure. Therefore, by controlling the inclination angle of the inlet between 2° and 15°, the buckle 2 can be smoothly inserted into the insertion channel, and the housing 3 can be made easier to manufacture.
[0060] For example, the specific degree of the lead-in angle can be: 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°. In another embodiment, the value range of the lead-in angle can be selected between any two of the above parameter values. Here, no restrictions are placed on the specific parameters of the lead-in angle.
[0061] Furthermore, the outer casing 3 is provided with a hollow column 32, which is integrally connected to the outer casing 3 and is disposed through the inner and outer sides of the outer casing 3. The hollow column 32 is hollow inside and open at both ends, forming an insertion and removal channel 31 inside the hollow column 32.
[0062] Based on the above solution, by setting the hollow column 32, a plug-in channel 31 with a larger length can be obtained, which is beneficial to improving the connection stability of the buckle 2; in addition, the hollow column 32 can also lift the button body 1 to form a certain assembly height, so that the user can touch the button body 1 and improve the user experience.
[0063] Optionally, the protrusion height of the hollow column 32 is 8mm-15mm. It is understood that the protrusion height is defined here as D1, referring to... Figure 3 The protrusion height of the hollow column 32 can be understood as the protrusion height of the hollow column 32 on the outer side of the outer shell 3, which is directly related to the assembly height of the button body 1. It can be understood that when the protrusion height of the hollow column 32 is less than 8mm, the installation height of the button body 1 may be too low. Since the adjustment switch is usually located on the side of the seat, it is inconvenient to observe, and the button body 1 is not easy for the user to touch. On the other hand, when the protrusion height of the hollow column 32 is greater than 15mm, the assembly height of the button body 1 will be too high, which may affect the structural compactness of the assembly and may cause expansion interference with other components. Therefore, when the protrusion height of the hollow column 32 is 8mm-15mm, its installation height is more moderate and meets the actual use requirements.
[0064] For example, the protrusion height of the hollow column 32 can be 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm. There is no limitation on its specific protrusion height. In another embodiment, the value range of the protrusion height can be selected between any two of the above parameter values.
[0065] Furthermore, referring to Figure 3 and combined Figure 5 There are multiple elastic fasteners 4, such as two, four or six. It is understood that the specific number of elastic fasteners 4 can be adjusted according to actual needs, and no specific limit is made here. Based on this, multiple elastic fasteners 4 are arranged circumferentially along the opening of the insertion channel 31, and multiple elastic fasteners 4 form a bayonet in their natural state. The outline of the bayonet is smaller than the size outline of the snap-fit part 22. By applying external force, the snap-fit part 22 passes through the bayonet and is fastened to the end of the elastic fastener 4 to realize the snap-fit process.
[0066] In the above-described embodiments, the multiple elastic fasteners 4 form an integral structure that can fasten and fix the snap-fit part 22 in multiple directions, making the snap-fit 2 more stable and less prone to loosening during assembly.
[0067] In this embodiment, combined with Figure 5 There are two elastic fasteners 4, which are arranged opposite to each other. The two elastic fasteners 4 can meet the most basic snap-fit stability, and they have the advantages of convenient molding, easy demolding and low molding cost, which is conducive to promotion and application.
[0068] Example 2:
[0069] Based on Embodiment 1, features not explained in this embodiment are explained using the methods described in Embodiment 1, and will not be repeated here. This embodiment provides a switch assembly using the following technical solution:
[0070] Reference Figure 6 A switch assembly includes the seat adjustment button mounting structure for preventing functional failure shown in Embodiment 1, and also includes a switch module 5. The switch module 5 includes components such as a circuit board, a slider, and a rocker switch. The switch module 5 is disposed in the housing 3 and connected to the button body 1. By moving the button body 1, the rocker switch can be triggered, thereby realizing the control function. The specific structure of the switch module 5 is prior art and will not be described in detail here.
[0071] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
