Description

Technical Field

[0001] This utility model belongs to the field of automotive parts, specifically relating to a convenient toggle switch mounting structure and an automobile. Background Technology

[0002] In the control panels of home appliances such as air conditioners and refrigerators, toggle switches are a common user operation component, widely used for functions such as mode switching, fan speed adjustment, and temperature setting. As consumers' requirements for the ease of operation, aesthetics, and durability of home appliances continue to increase, the traditional toggle switch structure is revealing more and more technical bottlenecks in practical applications.

[0003] Traditional toggle switch installation methods often use screw fastening or single snap-fit ​​connection, which not only involves complex and time-consuming assembly processes, increasing labor costs and error risks on the production line, but also makes them prone to loosening, abnormal noise, or even falling off due to vibration or repeated pressing during long-term use. As a result, toggle switches are prone to deformation and occasional failures during long-term use, making it impossible for the transmission rod to accurately move the required air conditioning button, ultimately affecting normal use due to functional failure and seriously impacting the user experience. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a convenient toggle switch mounting structure and automobile that is simple in structure, easy to assemble, highly stable, and prevents contact loss.

[0005] The purpose of this utility model can be achieved by addressing the following technical problem: proposing a convenient toggle switch mounting structure for assembling the toggle switch onto the mounting frame.

[0006] The mounting frame is provided with a positioning block and a transmission rod. The side wall of the positioning block forms a limiting part, which is used to limit the movement of the knob relative to the mounting frame. The transmission rod is connected to the air conditioning button inside the mounting frame.

[0007] The dial is provided with an assembly block and a guide block. The assembly block has a guide slope, which guides the assembly block into the limiting part, so that the dial is movably connected to the mounting frame. The end of the guide block moves against the transmission rod to drive the transmission rod to turn the air conditioning button. The guide block is symmetrically provided with reinforcing ribs to prevent the guide block from deforming and breaking contact with the transmission rod.

[0008] In the aforementioned convenient toggle switch installation structure, a positioning inclined surface is also formed on the limiting part, and the guiding inclined surface moves against the positioning inclined surface.

[0009] In the above-mentioned convenient toggle switch installation structure, a cavity is formed inside the toggle switch, the reinforcing rib is connected to the inner wall of the cavity, and a plurality of reinforcing blocks are provided at the inner wall of the opening of the cavity.

[0010] In the above-mentioned convenient toggle switch installation structure, the assembly block is provided with an installation hole, and the limiting part is formed with an arc surface and a clearance plane. The arc surface is movably close to the installation hole, and the clearance plane reduces the contact area between the two when they rotate relative to each other.

[0011] In the above-mentioned convenient toggle switch installation structure, the end of the guide block is formed with a concave arc groove, the end of the transmission rod is formed with a guide arc surface, and the concave arc groove is movably pressed against the guide arc surface.

[0012] In the aforementioned convenient toggle switch installation structure, the outer wall of the toggle switch is further provided with several equally spaced friction strips.

[0013] In the above-mentioned convenient toggle switch installation structure, the toggle switch is arranged in a trapezoidal shape, and the larger end cross-sectional area of ​​the trapezoid is the opening position of the cavity.

[0014] In the above-described convenient toggle switch mounting structure, an extension rib is formed at the end of the guide block away from the reinforcing rib, and the extension rib is connected to the opening of the cavity.

[0015] In the aforementioned convenient toggle switch mounting structure, a limiting hole is also provided on the mounting frame, and the transmission rod is movably inserted into the limiting hole and is clearance-fitted with the limiting hole.

[0016] The technical solution adopted by this utility model to solve its technical problem is to also propose an automobile, including one of the above-mentioned convenient toggle switch mounting structures.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This utility model provides a convenient toggle switch installation structure and a car. By cooperating with the limiting part on the mounting frame through the guide slope, the toggle switch is automatically guided and positioned during the installation process, which simplifies the assembly process and improves assembly efficiency and consistency. The end of the guide block on the toggle switch directly abuts against the transmission rod, which can accurately transmit the user's operating force to the air conditioning button to realize function control. At the same time, the guide block is symmetrically set with reinforcing ribs, which significantly enhances the structural strength of the guide block, effectively prevents plastic deformation caused by long-term pressing or external force, avoids the problem of broken contact or poor contact between the guide block and the transmission rod, and ensures the stable transmission of control signals.

[0019] (2) The arc surface can fit tightly with the mounting hole, providing a stable rotation fulcrum and ensuring smooth rotation of the dial; while the design of the avoidance plane reduces the contact area between the limiting part and the mounting hole when they rotate relative to each other, effectively reducing frictional resistance, avoiding jamming, and making the dial operation smoother.

[0020] (3) The concave arc groove and the guide arc surface at the end of the transmission rod form an arc-to-arc mating structure, which can achieve automatic alignment during relative movement, reduce stress concentration caused by assembly deviation, and effectively prevent failure caused by local wear or point contact.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] like Figure 1As shown, this solution mainly describes a convenient toggle switch 1 mounting structure for use in automobiles. However, this convenient toggle switch 1 mounting structure is not limited to use in automobiles, but can also be applied to other devices that require the toggle switch 1 structure.

[0031] like Figures 1 to 5 As shown, a convenient mounting structure for a dial 1 is provided for assembling the dial 1 onto a mounting frame 2. The mounting frame 2 is provided with a positioning block 20 and a transmission rod 21. The side wall of the positioning block 20 forms a limiting portion 200, which restricts the movement of the dial 1 relative to the mounting frame 2. The transmission rod 21 is connected to an air conditioning button within the mounting frame 2. The dial 1 is provided with an assembly block 10 and a guide block 11. The assembly block 10 has a guide slope 100, which guides the assembly block 10 into the limiting portion 200, allowing the dial 1 to be movably connected to the mounting frame 2. The end of the guide block 11 movably abuts against the transmission rod 21 to drive the transmission rod 21 to move the air conditioning button. Reinforcing ribs 110 are symmetrically provided on the guide block 11 to prevent deformation of the guide block 11 and loss of contact with the transmission rod 21.

[0032] like Figures 1 to 5 As shown, during the assembly process, the operator can pre-assemble the transfer rod 21 onto the mounting frame 2, and then perform the assembly operation after aligning the dial 1 with the mounting frame 2. Specifically, since the assembly block 10 is provided with a guide slope 100, when the dial 1 is pressed towards the mounting frame 2, the guide slope 100 first contacts the limiting part 200. At this time, the guide slope 100 plays a guiding role. Even if there is a slight assembly deviation, the position can be automatically corrected by sliding the guide slope 100 to guide the dial 1, so that the assembly block 10 gradually connects to the limiting part 200 and moves against the side wall of the positioning block 20, which significantly improves the assembly efficiency and convenience. At the same time, the end of the guide block 11 abuts against the transfer rod 21, which can effectively transmit the operating force of the dial 1 to the air conditioning button (not shown in the figure) to realize the function control. In particular, the symmetrically arranged reinforcing ribs 110 on the guide block 11 effectively enhance its structural strength, preventing plastic deformation or fracture under long-term frequent operation, and avoiding poor contact or even breakage with the transmission rod 21 due to deformation of the guide block 11, thereby ensuring the reliability and durability of operation. The overall structure realizes the quick installation, stable connection and reliable transmission of the dial 1, and has the advantages of simple structure, convenient assembly and stable operation.

[0033] like Figure 1 , Figure 2 as well as Figure 5As shown, in this embodiment, a positioning inclined surface 200a is provided on the limiting part 200, which moves and abuts against the guide inclined surface 100 on the assembly block 10. This allows the dial button 1 to form a surface contact fit during installation, improving the structural stability after assembly. Therefore, this inclined surface fit structure not only helps guide the alignment and sliding during assembly, but also provides a certain preload after assembly, reducing the shaking and abnormal noise of the dial button 1 during use, and improving the feel and operating accuracy. At the same time, the inclined surface fit is conducive to the uniform distribution of stress, reducing local stress concentration and extending service life.

[0034] A cavity 12 is formed inside the knob 1, and a reinforcing rib 110 is connected to the inner wall of the cavity 12. Several reinforcing blocks 120 are provided at the inner wall of the opening of the cavity 12.

[0035] like Figure 2 As shown, this embodiment includes a cavity 12 inside the toggle switch 1. This cavity 12 provides sufficient space for the design of other components and helps reduce the overall weight of the toggle switch 1, achieving a lightweight structural design. The reinforcing block 120 effectively improves the overall structural rigidity and torsional resistance of the toggle switch 1, preventing overall deformation due to external forces. This avoids cracking or deformation of the toggle switch 1 due to concentrated stress during assembly or use, significantly improving the mechanical strength and durability of the toggle switch 1, making it suitable for frequently operated automotive control components.

[0036] The assembly block 10 has a mounting hole 101, and the limiting part 200 has an arc surface 200b and a clearance surface 200c. The arc surface 200b is movably attached to the mounting hole 101, and the clearance surface 200c reduces the contact area between the two when they rotate relative to each other.

[0037] like Figure 1 , Figure 2 as well as Figure 5 As shown, this embodiment provides a mounting hole 101 on the assembly block 10 and an arc surface 200b and a clearance surface 200c on the limiting part 200. This allows the arc surface 200b to fit tightly against the mounting hole 101, providing a stable rotation fulcrum and ensuring smooth rotation of the dial 1. The clearance surface 200c reduces the contact area between the limiting part 200 and the mounting hole 101 during relative rotation, effectively reducing frictional resistance and preventing jamming, thus making the dial 1 operate more smoothly. This structure balances connection stability and operational flexibility, improving the user experience.

[0038] The end of the guide block 11 has a concave arc groove 111, and the end of the transmission rod 21 has a guide arc surface 210. The concave arc groove 111 is movably pressed against the guide arc surface 210.

[0039] like Figure 4As shown, in this embodiment, a concave arc-shaped groove 111 is provided at the end of the guide block 11, forming an arc-to-arc mating structure with the guide arc surface 210 at the end of the transmission rod 21. This enables automatic alignment during relative movement, reducing stress concentration caused by assembly deviations. Simultaneously, the arc-shaped contact has a large contact area and good stress distribution characteristics, effectively dispersing contact stress during transmission and preventing failures caused by localized wear or point contact. This design improves the reliability and stability of force transmission, reduces wear and noise during movement, and extends the service life of the transmission structure.

[0040] Preferably, such as Figure 3 As shown, in this embodiment, several equally spaced friction strips 13 are provided on the outer wall of the dial 1, which can significantly increase the friction between the user's fingers and the dial 1, prevent slippage during operation, and enable precise operation, especially in wet conditions or when wearing gloves. In addition, the regular distribution of the friction strips 13 also enhances the aesthetics of the product and the ergonomic experience, making operation more comfortable and intuitive.

[0041] More preferably, such as Figure 3 As shown, in this embodiment, the toggle switch 1 is designed as a trapezoidal structure, with the opening of the cavity 12 located at the larger end of the trapezoid. This allows stress to diffuse towards the larger end when the toggle switch 1 is subjected to force, improving the structure's load-bearing capacity and bending resistance. The larger end, as a load-bearing support surface, facilitates the uniform transmission of force, reducing the risk of localized deformation. Furthermore, this ergonomic design facilitates finger pinching operation, enhancing grip and ease of use. In addition, the trapezoidal structure also facilitates mold demolding, reducing manufacturing difficulty and cost.

[0042] An extension rib 112 is formed at the end of the guide block 11 away from the reinforcing rib 110, and the extension rib 112 is connected to the opening of the cavity 12. Figure 2 As shown, this structure can further enhance the connection strength between the guide block 11 and the main body of the toggle switch 1, forming a multi-point support structure, effectively preventing the guide block 11 from cantilever bending or breaking under stress. The extension rib 112 and the reinforcing rib 110 work together to form a stable support frame, significantly improving the structural reliability of the guide block 11 in long-term reciprocating motion and avoiding functional failure due to fatigue fracture.

[0043] like Figure 5 As shown, in this embodiment, a limiting hole 22 is provided on the mounting frame 2, and the transmission rod 21 is movably inserted into it with a clearance fit. This allows for precise guidance of the movement direction of the transmission rod 21, ensuring that it moves linearly along a predetermined trajectory and avoiding deviation or jamming. The clearance fit design allows the transmission rod 21 to have a certain tolerance space during movement, preventing the movement from being obstructed or the wear from being aggravated due to excessive tightness, which would affect the precise control of the air conditioning button. This improves the transmission accuracy and operational stability, ensuring that the air conditioning button is accurately triggered.
