Description

Technical Field

[0001] This utility model relates to the field of vehicle interior structure technology, specifically to a bright strip assembly structure and a toggle switch. Background Technology

[0002] All existing vehicles are equipped with air conditioning systems. To facilitate adjusting the airflow direction and volume from the air vents, an adjustment mechanism is typically located at the vent. A common adjustment mechanism is a toggle switch. Manually turning the switch horizontally adjusts the tilt angle of the air deflectors within the vent. When multiple deflectors rotate simultaneously, changing their angles alters the airflow volume and direction. To enhance the comfort and aesthetics of the toggle switch, a decorative rubber strip is installed at the end of the switch closest to the driver's compartment. This strip protrudes beyond the switch's end, ensuring contact with the strip during manual operation and improving comfort.

[0003] The current decorative trim strip is U-shaped, with a U-shaped mounting groove at the end of the toggle switch body to mate with it. The trim strip is then fixed in the groove via adhesive or other methods. While this method secures the trim strip, in practice, it presents several challenges. First, the rubber trim strip is more prone to damage than the plastic toggle switch body and other components. Furthermore, the trim strip is frequently moved and compressed during use, resulting in a shorter lifespan compared to other parts of the toggle switch. Damage to the trim strip necessitates replacing the entire toggle switch, leading to significant repair costs. Second, different customers have varying preferences for the trim strip's color and other features. Replacing the entire toggle switch requires replacement, which is laborious and complex, typically requiring technical assistance, making replacement inconvenient and costly. Utility Model Content

[0004] The present invention aims to provide a bright strip assembly structure and a toggle switch to solve the problem in the prior art that when the bright strip of a vehicle toggle switch is damaged and the entire assembly needs to be replaced, the disassembly and assembly operation is inconvenient and the replacement cost is high.

[0005] To solve the above problems, the present invention adopts the following technical solution: a decorative strip assembly structure, including a toggle body, one end of which has a U-shaped mounting groove, and a decorative strip is detachably connected in the mounting groove. The decorative strip is composed of a horizontal straight section and curved sections at both ends of the horizontal straight section, forming a U-shaped structure. Each of the two curved sections of the decorative strip is provided with an end insertion part, and both ends of the mounting groove are provided with end locking parts that engage with the end insertion parts. The horizontal straight section of the decorative strip is provided with a middle insertion part, and the toggle body is provided with a middle locking part that engages with the middle insertion part.

[0006] The principle of this solution is as follows: the horizontal and vertical sections of the decorative bright strip and the curved sections at both ends of the horizontal and vertical sections form a U-shaped structure. A U-shaped mounting groove is set on the toggle body. The U-shape of the mounting groove matches the U-shaped structure of the decorative bright strip. During installation, the decorative bright strip can be simply inserted into the mounting groove to achieve a certain degree of snap-fit ​​fixation. At the same time, this application provides end plug-in parts on the curved sections at both ends of the decorative bright strip, and end snap-fit ​​parts that engage with the end plug-in parts are set at both ends of the mounting groove. After the decorative bright strip is installed into the mounting groove, the end plug-in parts on the curved sections at both ends can be snapped into the end snap-fit ​​parts, so that the two ends of the decorative bright strip and the toggle body form a snap-fit ​​fixation relationship, further improving the connection stability between the decorative bright strip and the toggle body.

[0007] Furthermore, this application features a central insertion portion on the horizontal section and a central locking portion on the toggle body that engages with the central insertion portion. When the decorative trim is installed into the mounting groove, the engagement between the central insertion portion and the central locking portion ensures that not only the horizontal section in the middle of the decorative trim connects to the toggle body, but also that both ends and the middle of the decorative trim connect to the toggle body. This effectively guarantees the stability of the connection between the decorative trim and the toggle body, reducing the risk of the decorative trim slipping off the toggle body during use. More importantly, because this application… The design incorporates a central insertion part on the horizontal section. This central insertion part engages with the central locking part on the toggle switch body. When the horizontal section is subjected to a force along its length, the lateral resistance from the central insertion part prevents it from moving laterally. This prevents the decorative strip from easily detaching from the toggle switch body under lateral force. The force exerted on the decorative strip during use is along the length of the horizontal section (when manually adjusting the airflow direction and volume of the air conditioner vents, the force applied to the toggle switch is primarily along the length of the horizontal section). Therefore, the central insertion part not only secures the decorative strip in the middle but also provides a stabilizing effect along the length of the horizontal section, preventing it from easily detaching from the mounting groove under stress and improving the stability of the decorative strip during use.

[0008] The beneficial effects of this plan are:

[0009] 1. The decorative trim strip can be easily installed and removed: Compared to existing technologies where the decorative trim strip is completely fixed to the toggle switch body, requiring the entire toggle switch to be replaced if the trim strip is damaged, which is not only cumbersome to install and remove but also increases replacement costs, in this application, since the decorative trim strip is made of rubber, the curved sections at both ends of the trim strip are engaged with the end locking parts at both ends of the mounting groove through end plugs, and the horizontal and vertical sections are engaged with the middle plug and middle locking parts. When the trim strip is damaged, the locking parts can be easily pried off the toggle switch body by external force, and then a new trim strip can be easily installed into the mounting groove. This allows for convenient and quick installation of the trim strip, eliminating the need to replace the entire toggle switch as in existing technologies, effectively reducing replacement costs, and making replacement more convenient and efficient.

[0010] 2. The decorative bright strip can be stably connected to the toggle body: In this application, since the end plugs on the two curved sections play a snap-fit ​​and fixing role on both ends of the decorative bright strip, and the middle plugs on the horizontal section play a snap-fit ​​and fixing role on the middle position of the decorative bright strip, the entire decorative bright strip is stably installed on the toggle body, and is very stable in use.

[0011] 3. The decorative strip is not easily deformed or slipped during use: In this application, since a middle insertion part is set on the horizontal section, and the middle insertion part and the middle snap-fit ​​part are engaged, the force exerted on the decorative strip by the user during the use of the toggle is mainly along the length of the horizontal section. Therefore, relying on the middle insertion part set on the horizontal section in this application, the stability of the connection between the horizontal section and the toggle body can be effectively improved, and slippage during use can be effectively avoided.

[0012] 4. Car owners can change the decorative trim according to their preferences: In this application, since the decorative trim can be easily replaced individually and the replacement cost is low, car owners can change the decorative trim to different colors according to their preferences at a low cost, which makes the toggle switch more widely accepted in the market.

[0013] Preferably, as an improvement, the end plug portion includes an end plug protrusion that protrudes into the U-shaped structure of the decorative bright strip, and the end snap portion includes an end snap groove, wherein the side of the end plug protrusion facing the horizontal section contacts the inner wall of the end snap groove.

[0014] In this design, the end-mounted protrusion is designed to protrude into the U-shaped structure of the decorative strip. When the end-mounted protrusion is inserted into the end-mounted slot, the side of the end-mounted protrusion facing the horizontal section contacts the inner wall of the end-mounted slot. The entire end-mounted protrusion is hooked into the end-mounted slot like a hook, and both ends of the decorative strip are locked in place, so that the decorative strip is pressed tightly into the mounting groove, and the connection is stable.

[0015] Preferably, as an improvement, the inner wall of the end engaging groove that contacts the side of the end insertion protrusion facing the horizontal section is inclined outward from the toggle body.

[0016] In this design, the inner wall of the end-fitting groove that contacts the side of the end-fitting protrusion facing the horizontal section is inclined outward from the toggle body. When the decorative bright strip needs to be removed, the end-fitting protrusion needs to be pried outward from the end-fitting groove. At this time, since the contact surface that mates with the end-fitting protrusion is inclined outward from the toggle body, the force when prying the end-fitting protrusion outward can be effectively reduced, making the removal of the decorative bright strip easier.

[0017] Preferably, as an improvement, the intermediate insertion part includes an intermediate insertion protrusion fixedly connected to the horizontal section, the intermediate insertion protrusion being disposed on the side of the horizontal section facing the U-shaped structure; the intermediate snap-fit ​​part includes an intermediate snap-fit ​​groove disposed on the toggle body and communicating with the mounting groove.

[0018] In this design, the middle insertion protrusion is positioned on the side of the horizontal section facing the U-shaped structure. This facilitates the fixing of the middle insertion protrusion with the middle locking slot and prevents the middle insertion protrusion from protruding beyond the horizontal section facing away from the U-shaped structure, thus affecting the aesthetic appearance of the decorative strip.

[0019] Preferably, as an improvement, the number of intermediate insertion protrusions is one or more. When the number of intermediate insertion protrusions is more than one, the intermediate insertion protrusions are spaced apart along the length of the horizontal segment, and the thickness of the intermediate insertion protrusions is less than or equal to the thickness of the horizontal segment.

[0020] In this solution, one or more intermediate insertion protrusions can be reasonably set according to the length of the horizontal and vertical sections to effectively ensure the snap-fit ​​fixing effect of the horizontal and vertical sections; in addition, the thickness of the intermediate insertion protrusions in this solution is less than or equal to the thickness of the horizontal and vertical sections to avoid the intermediate insertion protrusions from protruding on both sides of the horizontal and vertical sections due to excessive thickness, which would affect the connection and fit between the horizontal and vertical sections and the mounting groove and affect the appearance of the decorative bright strip.

[0021] Preferably, as an improvement, the sidewall of the intermediate insertion protrusion is provided with an intermediate protruding rib that protrudes beyond the sidewall of the intermediate insertion protrusion, and the intermediate protruding rib contacts the inner wall of the intermediate snap-fit ​​groove.

[0022] In this design, a central protruding rib is provided on the side wall of the central insertion protrusion. During actual installation and use, the central protruding rib contacts the inner wall of the central locking groove. Compared to the central insertion protrusion directly contacting the inner wall of the central locking groove, the central protruding rib effectively reduces the contact area, thereby reducing abnormal noise during use. In addition, the central protruding rib is relatively narrow, making it easier to deform under compressive force. Therefore, when the central insertion protrusion is installed into the central locking groove, the central protruding rib can be compressed to form a good fit with the central locking groove, effectively improving the stability of the central insertion protrusion after installation.

[0023] Preferably, as an improvement, there are multiple intermediate protruding ribs, which are evenly distributed on both sides of the intermediate insertion protrusion, and all intermediate protruding ribs on the same side of the intermediate insertion protrusion are arranged along the length of the horizontal segment.

[0024] In this design, a central protruding rib is provided on both sides of the central insertion protrusion. After the central insertion protrusion is installed into the central snap-fit ​​groove, the force on both sides is more even. In addition, there is a gap between adjacent central protruding ribs. The central protruding ribs can be squeezed and deformed during the installation process without affecting the installation stability of the central insertion protrusion.

[0025] Preferably, as an improvement, the two ends of the intermediate insertion protrusion are provided with end chamfers, and the intermediate protruding rib is provided with an intermediate chamfer that cooperates with the intermediate snap-fit ​​groove.

[0026] In this solution, by setting end chamfers and middle chamfers, the end chamfers and middle chamfers provide guidance when the middle insertion protrusion is installed into the middle snap-fit ​​groove, making the installation process of the middle insertion protrusion more precise and efficient.

[0027] Preferably, as an improvement, an installation gap is provided between the inner side of the U-shaped structure of the decorative bright strip and the bottom wall of the mounting groove, and multiple contact ribs are provided on the side wall of the inner side of the U-shaped structure of the decorative bright strip, with the contact ribs spaced apart along the curve of the U-shaped structure of the decorative bright strip.

[0028] Similar to the function of setting a central protruding rib structure, this solution effectively reduces the contact area between the decorative bright strip and the inner wall of the mounting groove after installation by setting an installation gap and a contact rib structure. This reduces abnormal noise during the use of the decorative bright strip and improves the user experience. Therefore, to ensure the stability of the installation contact between the decorative bright strip and the inner wall of the mounting groove, at least one contact rib needs to be set on the horizontal section and the curved sections at both ends.

[0029] A toggle switch, including the aforementioned bright strip assembly structure.

[0030] In this solution, a bright strip assembly structure is provided in the toggle switch, which allows for easy disassembly and replacement of the decorative bright strip. When the decorative bright strip is damaged, it can be replaced quickly and at low cost. Attached Figure Description

[0038] The following detailed description illustrates the specific implementation method:

[0039] The reference numerals in the accompanying drawings include: toggle body 1, mounting groove 101, end snap-fit ​​groove 102, middle snap-fit ​​groove 103, decorative bright strip 2, horizontal section 201, curved section 202, end insertion protrusion 3, middle insertion protrusion 4, end chamfer 401, installation gap 5, contact rib 6, middle protruding rib 7, and middle chamfer 701.

[0040] Example 1

[0041] This embodiment is as shown in the appendix. Figure 1 As shown: A bright strip assembly structure includes a toggle body 1, combined with... Figure 2 Figure 3The top of the toggle body 1 has a U-shaped mounting groove 101. A decorative bright strip 2 is detachably connected inside the mounting groove 101. The decorative bright strip 2 consists of a horizontal straight section 201 and curved sections 202 integrally formed at both ends of the horizontal straight section 201. The thickness of the horizontal straight section 201 and the curved sections 202 are equal to ensure the stability of quality during the integral forming process. The horizontal straight section 201 and the curved sections 202 at both ends form a U-shaped structure. The U-shaped structure of the decorative bright strip 2 is adapted to the U-shape of the mounting groove 101 so that the decorative bright strip 2 can be accurately connected.

[0042] like Figure 2 As shown, both curved sections 202 of the decorative bright strip 2 are provided with end plugs, which are combined with Figure 3 Both ends of the mounting groove 101 are provided with end-engaging portions that engage with the end-engaging portions. Specifically, in this embodiment, the end-engaging portion includes an end-engaging protrusion 3 integrally formed on the curved section 202, and the end-engaging protrusion 3 protrudes into the U-shaped structure of the decorative bright strip 2; the end-engaging portion includes an end-engaging groove 102 formed on the side wall of the toggle body 1, wherein the end-engaging protrusion 3 contacts the inner wall of the side end-engaging groove 102 of the horizontal section 201, and is installed to... Figure 4 In the current state, the end insertion protrusions 3 on the two curved sections 202 are connected to the end locking grooves 102 like two hooks, so that the entire decorative bright strip 2 is limited and fixed in the mounting groove 101.

[0043] In addition, combined Figure 2 and Figure 4 To further improve the stability of the decorative bright strip 2 installed in the mounting groove 101, this embodiment provides an intermediate insertion part on the horizontal section 201, and an intermediate snap-fit ​​part on the toggle body 1 that engages with the intermediate insertion part. Specifically, the intermediate insertion part includes an intermediate insertion protrusion 4 fixed to the horizontal section 201 by integral molding, and the intermediate insertion protrusion 4 is located on the side of the horizontal section 201 facing the U-shaped structure, so as to form a snap-fit ​​fixed relationship with the toggle body 1. In this embodiment, the intermediate snap-fit ​​part includes an intermediate snap-fit ​​groove 103 integrally molded on the toggle body 1 and communicating with the mounting groove 101. When installing the intermediate insertion protrusion 4, simply insert the intermediate insertion protrusion 4 into the intermediate snap-fit ​​groove 103 to quickly complete the installation of the intermediate insertion protrusion 4. In practical applications, one or more intermediate insertion protrusions 4 can be provided according to the length of the horizontal segment 201. When there are multiple intermediate insertion protrusions 4, they are spaced apart along the length of the horizontal segment 201, and the thickness of the intermediate insertion protrusions 4 is less than or equal to the thickness of the horizontal segment 201. In this embodiment, there is one intermediate insertion protrusion 4, and the thickness of the intermediate insertion protrusion 4 is equal to the thickness of the horizontal segment 201.

[0044] In addition, combined Figure 1 , Figure 2 and Figure 4 In this embodiment, an installation gap 5 is provided between the inner side of the U-shaped structure of the decorative bright strip 2 and the bottom wall of the mounting groove 101. Multiple contact ribs 6 are provided on the side wall of the inner side of the U-shaped structure of the decorative bright strip 2. The contact ribs 6 are arranged at intervals along the curve of the U-shaped structure of the decorative bright strip 2. Specifically, the contact ribs 6 are integrally formed on the inner wall of the U-shaped structure of the decorative bright strip 2. The width of the contact ribs 6 is equal to the thickness of the horizontal section 201 and the curved section 202. At least one contact rib 6 is provided on the curved section 202 and at least two contact ribs 6 are provided on the horizontal section 201. By relying on the contact ribs 6, the contact area between the decorative bright strip 2 and the toggle body 1 is reduced, so as to reduce the abnormal noise generated during the use of the decorative bright strip 2.

[0045] In practical application, this embodiment features end-connecting protrusions 3 on the curved sections 202 at both ends of the decorative bright strip 2. During installation, these protrusions engage with the end-locking grooves 102 on the toggle body 1, securing both ends of the decorative bright strip 2. Simultaneously, the middle protrusion 4 on the horizontal section 201 engages with the middle locking groove 103, connecting the middle portion of the decorative bright strip 2 to the toggle body 1. This effectively ensures the stability of the connection between the decorative bright strip 2 and the toggle body 1, preventing the decorative bright strip 2 from detaching from the mounting groove 101 during use. When the decorative bright strip 2 is damaged, a prying tool can be inserted into the end-locking groove 102 to pry the end of the decorative bright strip 2 out of the end-locking groove 102, and then the middle protrusion 4 can be pulled out of the middle locking groove 103 to quickly remove the damaged decorative bright strip 2. A new decorative bright strip 2 can then be installed onto the toggle body 1.

[0046] A toggle switch includes the aforementioned decorative strip assembly structure, which allows the decorative strip 2 inside the toggle switch to be easily disassembled and replaced. When the decorative strip 2 is damaged, the replacement operation can be completed quickly and at low cost.

[0047] Example 2

[0048] The difference between Example 2 and Example 1 is as follows: Figure 5As shown, in this example, a central protruding rib 7 is integrally formed on the side wall of the central insertion protrusion 4, protruding beyond the side wall of the central insertion protrusion 4. There are multiple central protruding ribs 7, evenly distributed on both sides of the central insertion protrusion 4. All central protruding ribs 7 on the same side of the central insertion protrusion 4 are arranged along the length of the horizontal section 201. Both ends of the central insertion protrusion 4 are provided with end chamfers 401. The central protruding rib 7 is provided with a central chamfer 701 that mates with the central locking groove 103. When the central insertion protrusion 4 is inserted into… When the middle locking groove 103 is engaged, both the end chamfer 401 and the middle chamfer 701 can guide the middle insertion protrusion 4, allowing the middle insertion protrusion 4 to be inserted into the middle locking groove 103 more accurately and quickly to complete the installation. At the same time, after the middle insertion protrusion 4 is engaged and installed in the middle locking groove 103, the middle protruding rib 7 contacts the inner wall of the middle locking groove 103, reducing the contact area between the middle insertion protrusion 4 and the inner wall of the middle locking groove 103. This can also reduce abnormal noise during the use of the decorative bright strip 2.

[0049] Example 3

[0050] The difference between Example 3 and Example 2 is as follows: Figure 6 and Figure 7 As shown, in this embodiment, the inner wall of the end-engaging groove 102, which contacts the side of the end-engaging protrusion 3 facing the horizontal section 201, is inclined outward from the toggle body 1. Correspondingly, the side of the end-engaging protrusion 3 facing the horizontal section 201 is also inclined. When it is necessary to remove the decorative bright strip 2, since a prying tool is needed to pry the end-engaging protrusion 3 outward from the toggle body 1, this embodiment, by inclining the inner wall of the end-engaging groove 102 outward from the toggle body 1, can effectively reduce the force required to pry the end-engaging protrusion 3 outward, making it easier to remove the decorative bright strip 2.
