Description

Technical Field

[0001] This invention relates to the field of automotive combination switch technology, and more particularly to an automotive combination switch structure for dimming and steering conduction. Background Technology

[0002] Currently, the signal conduction structures for the turn signals and dimmer switches in automotive combination switches are mainly divided into traditional contact-type structures and 3D Hall effect structures. Contact-type structures primarily output hard-wired signals, and can also be used with PCBA boards to output bus signals. However, contact-type structures generate friction during mechanical sliding, which is transmitted to the switch operating handle, causing a scraping sensation when the user operates the handle. This is particularly noticeable in new energy vehicles where a quiet environment is required, making it difficult for customers to accept. 3D Hall effect structures primarily output bus-type signals. Their conduction structure uses a magnet and Hall effect sensor (non-contact) triggering, resulting in almost no scraping sensation during mechanical sliding. Users have high acceptance of the tactile feedback. However, this type of structure cannot directly output hard-wired signals, failing to meet diverse customer needs. Both of these conduction structures have limitations in application. To meet different customer requirements for signal types and tactile feedback, different structures need to be redesigned, increasing design and development costs and time. Therefore, designing a switch structure that can satisfy both hard-wired and bus signal output while also eliminating the scraping sensation during operation has become a technical problem that industry engineers need to solve.

[0040] A longitudinal slide groove 33 is provided on the base 3 above the first Hall sensor group 41. A light-changing magnet slider 31 is slidably connected in the longitudinal slide groove 33.

[0041] A transverse slide groove 34 is provided on the base 3 above the second Hall sensor group 42, and a steering magnet slider 32 is slidably connected in the transverse slide groove 34; the longitudinal slide groove 33 is perpendicular to the transverse slide groove 34; when the handle is moved up and down, the second slide post 61 at the lower end of the fork 6 drives the steering magnet slider 32 to slide laterally in the second slide groove 321.

[0042] The upper end of the light-changing magnet slider 31 is provided with a first slide groove 311, which is an arc groove; when the handle is moved up and down, the first slide post 51 at the lower end of the lever 5 moves along the arc path of the first slide groove 311; the upper end of the steering magnet slider 32 is provided with a second slide groove 321, which is parallel to the longitudinal slide groove 33; when the handle is moved back and forth, the second slide post 61 at the lower end of the fork 6 moves linearly along the second slide groove 321.

[0043] A fork 6 is sleeved and rotatably connected to the handle rod 11 of the handle 1. A lever 5 is rotatably connected to the fork 6. A first sliding post 51 is fixedly provided at the lower end of the lever 5, and the first sliding post 51 is slidably connected to the first sliding groove 311. To reduce friction, the lower end of the first sliding post 51 is designed with a spherical structure.

The second rotating shaft 54 ​​and the rotating groove 13 are rotatably and slidably connected, and the rotating groove 13 is arranged along the length direction of the handle 11.

[0048] In order to achieve the rotatable connection between the shift fork 6 and the handle rod 11, the two sides of the rear of the shift fork 6 are symmetrically provided with second pivot holes 62, and the two sides of the rear of the handle rod 11 are fixedly provided with third pivots 12, which are rotatably connected to the second pivot holes 62.

The fifth rotating shaft 66 and the fourth rotating shaft hole 35 are rotatably connected.

[0051] To avoid obstructing the lower end of the first sliding post 51 of the toggle block 5, and to facilitate the sliding of the first sliding post 51 within the first sliding groove 311 at the upper end of the light-changing magnet slider 31, such as... Figure 6 As shown, a clearance groove 67 is provided at the lower middle part of the shift fork 6, and the first sliding column 51 passes through the clearance groove 67.

[0052] To achieve a good gear shift feel, the handle rod 11 of the handle 1 is provided with a gear shift pin hole 14, and a spring 8 and a gear shift pin 9 are provided in the gear shift pin hole 14. A gear shift block 7 is provided on the base 3 at a position relative to the gear shift pin hole 14, and the gear shift block 7 is provided with a gear shift trajectory surface 71 adapted to the gear shift pin 9. Figure 11 As shown, the gear track surface 71 is provided with crisscrossing gear track grooves to accommodate the forward and backward movement and up and down movement of the gear pin 9.

[0053] To facilitate the installation and fixing of the gear block 7, such as Figure 2 As shown, the outer casing 2 is provided with a limiting groove 22, and the stop block 7 is fixedly connected in the limiting groove 22.

[0054] Working principle of the invention:

[0055] High / low beam headlight switching function:

[0056] By moving the handle 1 back and forth, the handle rod 11 rotates around the third rotating shaft 12 and pushes the shift fork 6 and the shift block 5 to slide along the longitudinal slide groove 33. As a result, the second sliding post 61 of the shift fork 6 slides longitudinally along the second slide groove 321, and the first sliding post 51 of the shift block 5 abuts against the side wall of the first slide groove 311, causing the light-changing magnet slider 31 to slide along the longitudinal slide groove 33.

[0057] At the same time, the lever 5 rotates around the first rotating shaft 53, causing the first sliding column 51 to rotate in the first sliding groove 311. Meanwhile, the second rotating shaft 54 ​​of the lever 5 rotates and slides in the rotating sliding groove 13 of the handle 11.

[0058] When the dimming magnet slider 31 slides along the longitudinal groove 33, the magnetic poles of the two sensors corresponding to the first Hall sensor group 41 will change, thereby triggering the first Hall sensor group 41 to switch between high and low levels to realize the dimming function of high and low beam lights.

[0059] like Figure 15 As shown, the three positions of the dimmer switch are OFF, overtaking, and high beam, with low level defined as 0 and high level as 1; when the S pole of the magnet contacts the Hall sensor, the high level changes to low level. The two Hall elements of the first Hall sensor group 41 can be numbered, and as the dimmer magnet slider 31 (e.g.) changes position... Figure 13 As shown, the movement of the N-pole (arranged in a Z-shape and the S-pole of two rectangular structures on the left and right) causes the two Hall elements to come into contact with different magnetic poles and identify their voltage changes, forming a gear signal list to determine the current dimming gear that the handle is in.

[0060] Turn signal function:

[0061] By moving the handle 1 up and down, the handle rod 11 drives the shift fork 6 to rotate around the fourth rotating shaft 21 and the fifth rotating shaft 66. At the same time, it drives the first sliding column 51 of the shift block 5 to slide along the first sliding groove 311. Meanwhile, the second sliding column 61 of the shift fork 6 drives the steering magnet slider 32 to slide along the transverse sliding groove 34. The magnetic poles of the four sensors of the second Hall sensor group 42 corresponding to the steering magnet slider 32 will change, thereby triggering the second Hall sensor group 42 to output a high-low level switch to realize the turn signal function.

[0062] like Figure 16 As shown, the five positions of the turn signal switch are OFF, left lane change, left turn, right lane change, and right turn. The four Hall elements of the second Hall sensor group 42 can be numbered, and the position is adjusted according to the turn signal slider 32 (e.g., ...). Figure 14As shown, the movement of the S-pole (arranged in a Z-shape and the N-pole of two L-shaped structures on the left and right) involves four Hall elements contacting different magnetic poles and identifying their voltage changes to form a gear signal list, thereby determining the steering gear currently engaged by the handle.
