Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a sealed combination switch assembly for automobiles and an automobile. Background Technology

[0002] With the rapid popularization of automobiles in people's lives, combination switches, as an essential component of automobiles, are favored by the public for their convenient and quick operation. Automotive sealed combination switch assemblies are installed on the steering column and are devices that control left or right turns, lights, washer fluid, or windshield wipers via a switch handle. These are components that require continuous operation during driving. Current automotive sealed combination switch assemblies integrate a ring-shaped structure near the base of the handle on the switch body to mate with surrounding interior plastic parts. However, this design makes the gap between the switch body and the surrounding plastic parts uncontrollable, easily leading to partial transparency issues, affecting the aesthetics, and potentially allowing foreign objects to enter the switch body, affecting its normal operation.

[0003] Therefore, there is an urgent need to develop a sealed combination switch assembly and automobile. Compared with existing technologies, the combination switch can completely cover the gap between the combination switch and the surrounding interior plastic parts during assembly, avoiding the problem of partial visibility and preventing foreign objects from entering the combination switch.

[0028] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a schematic diagram of the sealing seat. Figure 3 This is a schematic diagram of the seal. Figure 4 for Figure 3 Another structural diagram, such as Figure 1-4 As shown: The automotive sealed combination switch assembly of this embodiment includes a combination switch 1 and a drive lever assembly. The combination switch assembly is at least partially enclosed within the steering lock housing, and the drive lever assembly extends out of the steering lock housing. It also includes:

[0029] The sealing assembly includes a first sealing sub-assembly and a second sealing sub-assembly that are connected in a mating manner; most of the combination switch assembly is enclosed in the steering lock housing, and the combination switch 1 is provided with a drive rod assembly that extends out of the steering lock housing. The provision of a first sealing sub-assembly and a second sealing sub-assembly that mate with the first sealing sub-assembly can further improve the sealing effect.

[0030] The first sealing sub-assembly is used to seal the gap between the drive rod assembly and the steering lock housing, and the second sealing sub-assembly is used to seal the gap between the drive rod assembly and the combination switch 1. The steering lock housing (not shown in the figure) is an automotive interior trim piece near the combination switch 1. During assembly and installation, the drive rod assembly on the combination switch 1 extends out of the steering lock housing and forms a gap with the steering lock housing. By setting the sealing assembly, the gaps between the drive rod assembly and the steering lock housing and between the drive rod assembly and the combination switch 1 can be sealed. The sealing assembly can be a structure such as a sealing ring that can be inserted into the gap. The gap is sealed by the inner ring surface of the sealing ring being attached to the outer surface of the steering lock housing. Alternatively, it can be an elastically deformable element set on the steering lock housing and surrounding the gap. The gap is sealed by the deformation of the elastic element (such as rubber). At the same time, the drive rod assembly can also extend into the steering lock housing. By setting the sealing assembly to block the gap, foreign objects can be prevented from entering the combination switch 1, and the appearance can be made more refined.

[0031] In the existing technology, current automotive sealed combination switch assemblies integrate a ring structure near the base of the handle on the switch body for mating with surrounding interior plastic parts. However, this method makes the gap between the switch body and the surrounding interior plastic parts uncontrollable, easily leading to partial transparency issues, affecting the appearance's refinement. It may also allow foreign objects to enter the switch body, affecting the normal use of the combination switch 1. The automotive sealed combination switch assembly and automobile of this utility model, after the combination switch 1 is assembled, can seal the gap between the combination switch 1 and the steering lock housing by setting a sealing component, which can avoid the occurrence of partial transparency issues, prevent foreign objects from entering the combination switch 1, and improve the appearance's refinement.

[0032] In this embodiment, the drive rod assembly includes a drive rod 3 and a spherical component 2 that can be driven by the drive rod 3; the driving engagement method of the drive rod 3 and the spherical component 2 is an application of existing technology, and will not be described in detail here.

[0033] The first sealing sub-assembly is a sealing element 5, and the second sealing sub-assembly is a sealing seat 4. The sealing seat 4 is sleeved on the spherical part 2 and fixedly connected to the combination switch 1. The sealing element 5 is sealed and connected to the sealing seat 4, and its inner edge is tightly fitted with the spherical part 2. The drive rod 3 is connected to the combination switch 1 through a spherical part 2, which can prevent the formation of a hole between the drive rod 3 and the combination switch 1 during the rotation of the drive rod 3, thereby ensuring the safety of operation. Both the sealing element 5 and the sealing seat 4 are sleeved on the spherical part 2. The sealing seat 4 is fixedly connected to the combination switch 1. At the same time, the sealing element 5 is sealed and connected to the sealing seat 4, and its inner edge is tightly fitted with the spherical part 2, which facilitates the sealing of the gap between the drive rod assembly and the steering lock housing. The sealing seat 4 and the sealing element 5 can form a double sealing structure, which can improve the sealing effect and prevent dust and other debris from entering the steering lock housing and causing the combination switch 1 to malfunction.

[0034] In this embodiment, the sealing seat 4 has a ring-like structure. Two connecting rings 402 are provided on one side of the ring-like structure, spaced apart. The combination switch 1 has a connecting protrusion I 102 that matches the connecting rings 402, and the connecting rings 402 can engage with the connecting protrusion I 102. A connecting groove 405 is provided on the other side of the ring-like structure. The combination switch 1 has a connecting protrusion II that matches the connecting groove 405, and the connecting protrusion II can engage with the connecting groove 405. The sealing seat 4 has two connecting rings 402 on one side. Through the cooperation of the connecting rings 402 with the connecting protrusion I 102 on the combination switch 1 and the connecting protrusion II with the connecting groove 405, the connecting protrusion II (not shown in the figure) can be directly inserted into the connecting groove 405 during installation, thus achieving a fixed installation of the sealing seat 4. The overall installation structure is simple and easy to assemble.

[0035] In this embodiment, the sealing element 5 is an annular structure. The inner edge of the annular structure extends inward to form a sealing element annular protrusion 507, and the inner edge of the sealing seat 4 extends outward to form a sealing seat annular protrusion 403. The sealing element annular protrusion 507 is fixedly connected to the sealing seat annular protrusion 403, and the port of the sealing seat annular protrusion 403 is in close contact with the inner annular surface of the annular structure. "Inward" refers to the direction closer to the combination switch 1, and "outward" refers to the direction farther from the combination switch 1. The inner edge of the annular structure extends inward (i.e., the end of the inner wall of the annular structure closest to the combination switch 1 extends inward) to form the sealing element annular protrusion 507. 7. The inner edge of the sealing seat 4 extends outward (i.e., the end of the inner wall surface of the sealing seat 4 away from the combination switch 1 extends outward) to form the sealing seat annular protrusion 403. During assembly, the sealing element 5 is connected to the sealing seat annular protrusion 403 through the sealing element annular protrusion 507, thereby realizing the installation of the sealing element 5. At the same time, after the assembly is completed, the port of the sealing seat annular protrusion 403 (i.e. the end of the sealing seat annular protrusion 403 away from the combination switch) is tightly attached to the inner annular surface of the sealing element 5 (the inner annular surface is a ring structure and the surface near the combination switch), thereby realizing the sealing connection between the sealing element 5 and the sealing seat 4.

[0036] In this embodiment, a connecting ring groove 404 is formed on the sealing seat annular protrusion 403, and the sealing element annular protrusion 507 is inserted into the connecting ring groove 404 and fixedly connected to the sealing seat annular protrusion 403; the sealing seat annular protrusion 403 includes an inner annular protrusion and an outer annular protrusion, and a gap is formed between the inner annular protrusion and the outer annular protrusion, which is the connecting ring groove 404. The sealing element annular protrusion 507 is inserted into the connecting ring groove 404 and fixedly connected to the sealing seat annular protrusion 403, which facilitates assembly.

[0037] In this embodiment, the groove wall of the connecting ring groove 404 is provided with an internal thread, and the sealing ring protrusion 507 is provided with an external thread that matches the internal thread. The sealing ring protrusion 507 is threadedly connected to the sealing seat ring protrusion 403. The internal thread on the groove wall of the connecting ring groove 404 (i.e., the internal thread on the outer ring protrusion) and the external thread on the sealing ring protrusion 507 that matches the internal thread, along with the threaded connection of the sealing ring protrusion 507 to the sealing seat ring protrusion 403, can form a labyrinth seal at the connection point, thereby improving the sealing effect at the connection point.

[0038] In this embodiment, a positioning groove 401 is also included, which is disposed on one side of the sealing seat 4 and located between the two connecting rings 402. The combination switch 1 is provided with a positioning rib 101 that is adapted to the positioning groove 401. The positioning groove 401 can be engaged with the positioning rib 101. The positioning groove 401 is provided so that it can be engaged with the positioning rib 101, which facilitates the assembly and positioning of the sealing seat 4 and improves the assembly efficiency.

[0039] In this embodiment, the sealing element 5 includes a sealing half-ring I 504 and a sealing half-ring II 501 that are inserted into each other; the sealing half-ring I 504 and the sealing half-ring II 501 are inserted into each other, which facilitates the installation of the sealing element.

[0040] The sealing half-ring I 504 has insertion grooves 503 at both ends, and the sealing half-ring II 501 has insertion parts 502 at both ends that are adapted to the insertion grooves 503; or, the sealing half-ring I 504 has insertion grooves and insertion parts at both ends, and the sealing half-ring II 501 has insertion parts and insertion grooves corresponding to the sealing half-ring I at both ends; the sealing element 5 is a split structure, including sealing half-ring I 504 and sealing half-ring II 501, which are connected by insertion (i.e., insertion parts 502 are inserted into insertion grooves 503), so that it can adapt to drive rod assemblies of different sizes and can be adapted to various vehicle models;

[0041] The insertion part 502 is provided with insertion holes; during installation, the installation tool can be inserted into the two insertion holes to drive the sealing half ring I 504 and sealing half ring II 501 to be screwed into the sealing seat 4, thereby improving the installation efficiency.

[0042] In this embodiment, the inner edge of the sealing member 5 is provided with a brush 505, and the inner ring surface of the sealing member 5 is provided with a soft material 506. The inner edge of the sealing member 5 is provided with a brush 505 (that is, the end of the inner wall surface of the annular structure away from the combination switch 1 is provided with a brush 505). After installation, the brush 505 is in close contact with the spherical part 2. When in use, when the drive rod assembly drives the spherical part 2 to rotate, the brush 505 can clean the surface of the spherical part 2 and sweep away the dust on the outside of the spherical part 2, thereby further increasing the dustproof effect. The soft material 506 is provided on the inner ring surface of the sealing member 5. The soft material 506 can be rubber or the like. After installation, it can be in close contact with the outer surface of the turn lock housing, further improving the blocking effect of gaps, and at the same time having a certain waterproof effect, thus improving the service life of the combination switch 1.

[0043] The automobile of this embodiment includes the aforementioned sealed combination switch assembly. During assembly, the sealing seat 4 is first fixedly installed on the combination switch 1 (the drive rod assembly and the combination switch are a single unit), then the steering lock housing is installed, and finally the sealing element 5 is installed. This allows the sealing element 5 to further block the gap between the drive rod assembly and the steering lock housing, based on the sealing effect formed by the sealing seat 4. This prevents dust and other foreign objects from entering the combination switch 1, extends the service life of the combination switch 1, and improves the overall appearance of the vehicle. It also effectively solves the problem of partial transparency at this gap in the prior art.
