Description

Technical Field

[0001] This application relates to the technical field of control switches, and in particular, to a control switch. Background Art

[0002] With the continuous improvement of people's living standards and the continuous development of vehicle technology, people have more and more demands for the functions on vehicles. In order to meet the continuous improvement of people's driving needs, various multifunctional control switches are provided in the vehicle cockpit. However, most of the existing vehicle switches only have a single function. The higher the vehicle configuration, the more switches there are in the vehicle. A large number of switches make the operation panel messy, which is not convenient for the driver to operate and reduces driving safety. Among these switches, the roller switch is one of the common control switches in the vehicle cockpit, and it realizes the adjustment of different gears through its own rotation.

[0003] The existing roller switches on the market usually adopt a magnetic field sensor solution. The roller is rotatably arranged above the magnetic field sensor, and a magnetic ring is provided inside the roller. The rotation of the roller drives the magnetic ring to rotate synchronously, so that the magnetic field changes. The magnetic field sensor senses the change of the magnetic field and thus outputs a signal to realize the adjustment of different gears. However, in this solution using a magnetic ring, the change of the magnetic field during rotation is relatively small, and the magnetic field sensor is likely to fail to sense the change of the magnetic field, resulting in signal loss or no signal output, making the gear adjustment function ineffective, causing a poor user experience, and reducing the competitiveness of the vehicle in the market.

The magnetic member 130 can be a permanent magnet, and the magnetic field sensor 140 can be a Hall sensor.

[0046] In this embodiment, by rotatably connecting the rotating member 150 to the shielding bracket 110, the rotating member 150 can rotate relative to the shielding bracket 110, and by fixedly connecting the rolling member 120 to the rotating member 150, the rolling member 120 can synchronously rotate relative to the shielding bracket 110 following the rotating member 150, thereby driving a plurality of magnetic members 130 inside it to rotate synchronously, so that the magnetic field changes greatly and is sensed by the magnetic field sensor 140.

[0048] Such as Figure 1 and Figure 2 shown, in the above embodiment of the present application, optionally, the shielding bracket 110 is provided with a first mounting hole 111 and a second mounting hole 112, one end of the rotating member 150 is disposed in the first mounting hole 111 and is rotatably connected to the hole wall of the first mounting hole 111, and the end of the rotating member 150 away from the first mounting hole 111 is disposed in the second mounting hole 112 and is rotatably connected to the hole wall of the second mounting hole 112.

[0049] In this embodiment, by respectively providing the first mounting hole 111 and the second mounting hole 112 on the shielding bracket 110, one end of the rotating member 150 is disposed in the first mounting hole 111 and is rotatably connected to the hole wall of the first mounting hole 111, and the end of the rotating member 150 away from the first mounting hole 111 is disposed in the second mounting hole 112 and is rotatably connected to the hole wall of the second mounting hole 112, so as to realize the function of rotatably connecting the rotating member 150 to the shielding bracket 110, thereby enabling the rolling member 120 fixedly connected to the rotating member 150 to rotate relative to the shielding bracket 110.

[0050] Exemplarily, the two ends of the rotating member 150 may be rotatably connected to the first mounting hole 111 and the second mounting hole 112 respectively by a clearance fit.

[0052] In this embodiment, a third mounting hole 113 is opened on the shielding bracket 110 along an axial direction perpendicular to the rotating member 150, one end of the movable component 160 is movably set in the third mounting hole 113, and the end of the movable component 160 away from the third mounting hole 113 is movably abutted against the rotating member 150, so that the rotation of the rotating member 150 is damped under the action of the movable abutment between the movable component 160 and the rotating member 150, thereby effectively improving the user's operational feel when moving the rolling member 120.

[0053] like Figure 1 and Figure 3 As shown, in the above-mentioned embodiment of the present application, optionally, the movable component 160 includes a movable part 161 and an elastic part 162, one end of the movable part 161 is movably arranged in the third mounting hole 113, and the end of the movable part 161 away from the third mounting hole 113 is movably abutted against the rotating part 150, and the elastic part 162 is arranged in the third mounting hole 113, and respectively abuts against the bottom wall of the third mounting hole 113 and the end of the movable part 161 away from the rotating part 150.

[0054] In this embodiment, one end of the movable part 161 is movably set in the third mounting hole 113, and the end of the movable part 161 away from the third mounting hole 113 is movably abutted against the rotating part 150, so that the rotation of the rotating part 150 is damped under the movably abutting action of the movable part 161 and the rotating part 150, thereby effectively improving the user's operational feel for moving the rolling part 120.

[0055] At the same time, by setting the elastic member 162 in the third mounting hole 113, and respectively abutting against the bottom wall of the third mounting hole 113 and the end of the movable member 161 away from the rotating member 150, the movable member 161 and the rotating member 150 are always kept in abutment under the elastic force of the elastic member 162, so as to ensure the stability of the damping effect.

[0056] Exemplarily, the movable member 161 may be a movable column, and the elastic member 162 may be a cylindrical spring or a spring.

[0058] In this embodiment, a mounting post 114 is provided in the third mounting hole 113, and the elastic member 162 is movably sleeved on the mounting post 114, and respectively abuts against the bottom wall of the third mounting hole 113 and one end of the movable member 161 away from the rotating member 150. This can effectively improve the installation stability of the elastic member 162, so that under the elastic force of the elastic member 162, the movable member 161 and the rotating member 150 always maintain stable abutment, thereby further ensuring the stability of the damping effect.

When the user turns the rolling part 120 to drive the rotating part 150 to rotate synchronously by a preset angle, the movable part 161 changes from abutting with one of the arc-shaped matching parts 151 to abutting with another adjacent arc-shaped matching part 151. The damping feeling generated during the change process can be fed back to the user's finger to prompt the user whether the gear adjustment is in place, which effectively improves the accuracy of the gear adjustment and the user's experience.

[0063] Meanwhile, by providing an avoidance hole 171 on the shielding cover 170 for avoiding the rolling member 120, and the end of the rolling member 120 away from the shielding bracket 110 is disposed outside the shielding cover 170 through the avoidance hole 171, an operation position for the user is provided, facilitating the user to toggle the rolling member 120 with a finger.
