Abstract
Description
Technical Field
[0001] This utility model specifically relates to a one-button start switch for engineering vehicles. Background Technology
[0002] Traditional vehicle starting methods are gradually being replaced by one-button start methods, especially in engineering vehicles, where a combination of rotary knob and button is often used to achieve one-button start.
[0003] For example, the Chinese utility model patent document with publication number "CN211980452U" discloses a one-button start switch, which mainly consists of a base, a ring rotary switch, a button, a decorative ring, and a controller, and is suitable for engineering vehicle start systems.
[0004] According to paragraph 0025 of the publicly available document, to start the vehicle, the rotary switch needs to be rotated to shift gears before the start button is pressed. However, the positioning of the rotary switch before and after shifting gears relies on the interaction of a spring and a steel ball. The spring's elasticity causes the steel ball to press against the inner end face of the rotary switch, thus positioning it. With prolonged use, the spring is prone to fatigue, resulting in decreased restoring force and reduced contact force between the steel ball and the inner end face of the rotary switch. This drastically reduces the positioning effectiveness. Vehicle vibrations or accidental contact with the rotary switch can cause it to rotate back, directly rendering the one-button start switch ineffective. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a one-button start switch for engineering vehicles, which effectively prevents the rotary switch from rotating by setting an arc-shaped limit block and a positioning groove on the rotary switch.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-button start switch for engineering vehicles, including a base, a rotatable rotary switch connected to the top of the base, a button movably inserted into the center of the rotary switch through an annular hole, a guide connection hole corresponding to the button and fitting with the button clearance, a reset component linked to the button, and several sets of mounting holes on the end face of the base facing the rotary switch, each set of mounting holes containing a first spring and a steel ball, characterized in that: the rotary switch has a set of arc-shaped limiting blocks corresponding to each set of mounting holes, and positioning grooves are symmetrically arranged on both sides of each set of arc-shaped limiting blocks.
[0007] By incorporating an arc-shaped limiting block and a positioning groove on the rotary switch, the steel ball can be more stably engaged in the positioning groove under the action of the spring. Even if the vehicle vibrates or the rotary switch is accidentally touched, the cooperation of the arc-shaped limiting block and the positioning groove can effectively prevent the rotary switch from rotating back, thereby improving the reliability of positioning.
[0008] This application can be further configured such that: the end face of the base facing the rotary switch is provided with a plurality of guide posts, the mounting holes are distributed in the guide posts, and the end of the guide post facing the rotary switch is provided with an arc-shaped sliding groove, the two ends of the arc-shaped sliding groove respectively penetrating the two sides of the guide post.
[0009] Steel balls and springs are installed in the mounting holes of the guide post to improve the stability of the steel balls' movement. When the rotary switch rotates, the mounting holes and arc-shaped sliding grooves in the guide post guide the movement of the arc-shaped limit block, ensuring that it slides along a predetermined path. This ensures the rotary switch remains stable during rotation, reduces deviation caused by vibration or external forces, and minimizes jamming caused by vibration or external forces. This ensures the rotary switch moves smoothly during rotation, further enhancing the user experience.
[0010] This application can be further configured as follows: the base has a plurality of first hooks on the end face facing the rotary switch, the rotary switch has a set of fan-shaped holes corresponding to each set of first hooks, the hook body of the first hook passes through the fan-shaped holes and locks the rotary switch, the inner circumferential surface of the rotary switch has a first annular abutment surface, the outer circumference of the base has a limiting flange ring, the limiting flange ring is distributed below the first annular abutment surface and the two are partially stacked.
[0011] The first hook engages with the sector-shaped hole, and the first annular abutment surface engages with the limiting flange ring, limiting the rotary switch along the axial direction of the base to prevent it from floating up and down. Furthermore, the structural characteristics of the sector-shaped hole allow the rotary switch to rotate relative to the base, while limiting its maximum rotation angle to prevent excessive deflection.
[0012] This application can be further configured such that: the outer periphery of the limiting flange ring is provided with an annular groove, the inner circumferential surface of the rotary switch is provided with a first annular protrusion adapted to the annular groove, a first inclined surface is provided below the first annular protrusion, and a second inclined surface parallel to the first inclined surface is provided below the annular groove.
[0013] The first annular protrusion and annular groove cooperate to further limit the rotary switch along the axial direction of the base, preventing the rotary switch from floating up and down. The first inclined surface cooperates with the second inclined surface to facilitate the assembly of the rotary switch and the base without jamming.
[0014] This application can be further configured as follows: a decorative component is provided between the button and the rotary switch, the decorative component includes a first decorative ring sleeved on the outer periphery of the button, a second decorative ring sleeved on the outer periphery of the first decorative ring, a plurality of sets of second hooks provided on the lower end face of the first decorative ring, the rotary switch is provided with a matching insertion hole corresponding to each set of second hooks, the hook body part of the second hook passes through the insertion hole and locks the rotary switch, a first connecting ring is provided above the rotary switch, the second decorative ring is provided with a second connecting ring that fits against the inner peripheral surface of the first connecting ring, a second annular protrusion is provided on the inner peripheral surface of the second decorative ring, the first decorative ring is provided with a second annular abutment surface, the second annular abutment surface is distributed above the second annular protrusion surface and the two are partially overlapped.
[0015] Adding two decorative rings (a first decorative ring and a second decorative ring) enhances the product's visual appeal and adds depth. The first and second decorative rings can be made of different materials, colors, or textures; their combined design improves the overall visual effect. A second hook mates with the insertion hole, securing the first decorative ring to the rotary switch without it rotating. A first connecting ring mates with the second connecting ring, and a second annular protrusion mates with a second annular abutment surface, thus securing the second decorative ring between the first decorative ring and the rotary switch.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 6 The one-button start switch for the engineering vehicle shown includes a base 1. A rotatable rotary switch 2 is connected to the top of the base 1. A button 3 is movably inserted into the center of the rotary switch 2 through an annular hole 2a. The base 1 has a guide connection hole 1a corresponding to the button 3, which is clearance-fitted with the button 3. The button 3 is linked to a reset component (this reset component is a spring, which is common knowledge in the art and is therefore not shown in the attached figure). The end face of the base 1 facing the rotary switch 2 has several sets of mounting holes 1c. Each set of mounting holes 1c contains a first spring 4 and a steel ball 5. The rotary switch 2 has a set of arc-shaped limiting blocks 2b corresponding to each set of mounting holes 1c. Each set of arc-shaped limiting blocks 2b has symmetrically arranged positioning grooves 2c on both sides. By setting the arc-shaped limiting blocks 2b and positioning grooves 2c on the rotary switch 2, the steel ball 5 can be more stably locked into the positioning groove 2c under the action of the spring. Even if the vehicle vibrates or the rotary switch 2 is accidentally touched, the cooperation between the arc-shaped limit block 2b and the positioning groove 2c can effectively prevent the rotary switch 2 from rotating, thereby improving the reliability of positioning.
[0025] The base 1 has several sets of guide posts 1b on its end face facing the rotary switch 2. Mounting holes 1c are distributed within the guide posts 1b. An arc-shaped sliding groove 1d is provided at the end of the guide post 1b facing the rotary switch 2, with both ends of the arc-shaped sliding groove 1d penetrating both sides of the guide post 1b. A steel ball 5 and a spring are installed within the mounting holes 1c of the guide post 1b, improving the stability of the steel ball 5's movement. When the rotary switch 2 rotates, the mounting holes 1c and the arc-shaped sliding groove 1d within the guide post 1b guide the movement of the arc-shaped limiting block 2b, ensuring it slides along a predetermined path. This ensures the rotary switch 2 remains stable during rotation, reducing deviations caused by vibration or external forces, minimizing jamming caused by vibration or external forces, and ensuring smooth movement of the rotary switch 2 during rotation, further enhancing the user experience.
[0026] The base 1 has several sets of first hooks 1e on its end face facing the rotary switch 2. The rotary switch 2 has a set of fan-shaped holes 2d corresponding to each set of first hooks 1e. The hook body of the first hook 1e passes through the fan-shaped hole 2d and engages the rotary switch 2. The inner circumferential surface of the rotary switch 2 has a first annular abutment surface 2e. The outer circumference of the base 1 has a limiting flange ring 1f, which is distributed below the first annular abutment surface 2e and partially overlaps with it. The first hooks 1e engage with the fan-shaped holes 2d, and the first annular abutment surface 2e engages with the limiting flange ring 1f, limiting the rotary switch 2 along the axial direction of the base 1 to prevent the rotary switch 2 from floating up and down. Furthermore, utilizing the structural characteristics of the fan-shaped holes 2d, the rotary switch 2 can rotate relative to the base 1, while limiting the maximum rotation angle of the rotary switch 2 to prevent excessive deflection.
[0027] The outer circumference of the limiting flange ring 1f is provided with an annular groove 1g, and the inner circumferential surface of the rotary switch 2 is provided with a first annular protrusion 2f that matches the annular groove 1g. Below the first annular protrusion 2f is a first inclined surface 2g, and below the annular groove 1g is a second inclined surface parallel to the first inclined surface 2g. The first annular protrusion 2f and the annular groove 1g cooperate with each other to further limit the rotary switch 2 along the axial direction of the base 1, preventing the rotary switch 2 from floating up and down. The first inclined surface 2g cooperates with the second inclined surface to facilitate the assembly of the rotary switch 2 and the base 1 without jamming.
[0028] A decorative component is provided between the button and the rotary switch 2. The decorative component includes a first decorative ring 6 fitted around the outer periphery of the button, and a second decorative ring 7 fitted around the outer periphery of the first decorative ring 6. The lower end face of the first decorative ring 6 has several sets of second hooks 6a. The rotary switch 2 has a matching insertion hole 2h corresponding to each set of second hooks 6a. The hook body of the second hook 6a passes through the insertion hole 2h and engages with the rotary switch 2. A first connecting ring 2i is provided above the rotary switch 2. The second decorative ring 7 has a second connecting ring 7a that fits against the inner periphery of the first connecting ring 2i. The inner periphery of the second decorative ring 7 has a second annular protrusion 7b. The first decorative ring 6 has a second annular abutment surface 6b, which is distributed above the second annular protrusion 7b and partially overlaps with it. The use of two decorative rings (the first decorative ring 6 and the second decorative ring 7) increases the product's sense of layering and aesthetics. The first decorative ring 6 and the second decorative ring 7 can use different materials, colors, or textures; through combined design, the overall visual effect of the product can be enhanced. The second hook 6a is adapted to the insertion hole 2h, so that the first decorative ring 6 is fixedly installed on the rotary switch 2 and the first decorative ring 6 will not rotate. The first connecting ring 2i cooperates with the second connecting ring 7a, and the second annular protrusion 7b cooperates with the second annular abutment surface 6b, so that the second decorative ring 7 is fixedly installed between the first decorative ring 6 and the rotary switch 2.
