Description

Technical Field

[0001] This utility model relates to the field of automotive electronic switch technology, specifically a novel 360-degree roller switch. Background Technology

[0002] With the continuous improvement of people's living standards and the continuous development of automotive technology, people's demands for car functions are also increasing. To meet the ever-increasing driving needs, various multi-functional control switches are installed in the car cockpit, such as push-button switches, toggle switches, and scroll wheel switches. Among them, the scroll wheel switch is one of the most common control switches in the car cockpit. Its rotation allows for adjustment of different gears, making the operation of the entertainment system's volume control or up / down selection functions more convenient and smooth. However, existing scroll wheel switches have the problem of unclear gear shifting operation, easily leading to over-shifting or under-shifting. Summary of the Invention

[0003] To address the problem of unclear shifting operation in existing roller switches, this invention provides a novel 360-degree roller switch.

[0004] This utility model is achieved using the following technical solution: A novel 360-degree roller switch includes a switch cover, a roller assembly, a bracket cover, and a PCB device. The bracket cover is fixed on the PCB device, and a fixed bracket is fixed above the bracket cover. The roller assembly is assembled on the fixed bracket. The switch cover is installed on the bracket cover to cover the roller assembly, with the roller protruding from the upper part of the switch cover. The roller assembly includes a roller, a roller bracket, a grating shielding fan blade, and a slotted photoelectric sensor. The roller bracket includes a frame with roller shaft holes, one side of which is a round hole and the other side is a square hole. The roller includes a roller body, a spring, a ball, a square shaft, and a round shaft. A ring of corrugated teeth is provided on the inner circumference of the roller body, with alternating peaks and troughs. One end of the round shaft is connected to a gear mechanism. The other end of the shaft is inside the roller body. The middle part of the round shaft is connected to the roller body. After the round shaft is assembled in the round hole on the roller bracket, the roller body is installed on the roller bracket. One end of the square shaft is provided with a hollow platform. The top of the hollow platform is provided with a ball hole. The hollow platform is located inside the roller body. After the square shaft is fixed in the square hole on the roller bracket, the hollow platform is suspended in the roller body. The spring is located inside the hollow platform and is in a compressed state inside the hollow platform. The ball is located at the top of the spring, and the ball partially protrudes from the cylindrical hole of the hollow platform. The protruding part of the ball is located in the trough of the corrugated teeth. The gear mechanism is connected to the grating blocking fan blade drive. The slotted photoelectric sensor is fixed on the roller bracket. The grating blocking fan blade is located in the slot of the slotted photoelectric sensor. The slotted photoelectric sensor is connected to the PCB board in the PCB device.

[0005] This utility model relates to a roller switch installed on a car steering wheel. During operation, the finger rolls the roller, changing the contact position between the inner corrugated teeth and the ball. When the contact position reaches the next trough, a gear adjustment is completed. Simultaneously, the roller drives the grating blocking fan blades to rotate via a gear mechanism. After rotation, the grating blocking fan blades block the signal of the slotted photoelectric sensor, which then transmits the signal to the PCB board. The redesigned roller structure of this utility model achieves gear adjustment through the cooperation of the ball and corrugated teeth. When the ball reaches a new trough of the corrugated teeth, the driver can clearly feel the gear change, resulting in precise gear selection. The roller can rotate 360 ​​degrees smoothly, achieving stepless gear adjustment.

[0006] The aforementioned novel 360-degree roller switch includes a gear mechanism comprising a first moving gear, a second moving gear, and a third moving gear. One end of a circular shaft is connected to the first moving gear. The second moving gear is mounted on a second moving gear shaft on a roller bracket. The third moving gear is connected to one end of a concentric shaft on the roller bracket. A grating is installed at the other end of the concentric shaft to block the fan blades. The first moving gear meshes with the second moving gear, and the second moving gear meshes with the third moving gear. This invention employs a three-stage gear mechanism, which can precisely control the rotation of the grating-blocked fan blades, thereby enabling the slotted photoelectric sensor to provide a precise gear position signal.

[0007] The aforementioned novel 360-degree roller switch has a roller body divided into a large roller and a small roller, with the small roller inside the large roller and connected to it.

[0008] The aforementioned novel 360-degree roller switch includes a roller cover, which is connected to one end face of the small roller, and the middle part of the round shaft is connected to the roller cover.

[0009] The aforementioned novel 360-degree roller switch has a groove on the outer circumference of the small roller and a convex strip on the inner circumference of the large roller. The small roller and the large roller are connected by the cooperation of the convex strip and the groove.

[0010] The aforementioned novel 360-degree roller switch has a notch on one side of the small roller and a protrusion on one side of the roller cover. The small roller and the roller cover are connected through the cooperation of the notch and the protrusion.

[0011] The aforementioned novel 360-degree roller switch has a PCB device comprising a PCB board, a PCB top cover, and a PCB bottom cover, with the PCB board located within the cover body composed of the PCB top cover and the PCB bottom cover.

[0012] The aforementioned novel 360-degree roller switch features a fixed bracket with a vertical groove and a slide rail on the frame. The frame and fixed bracket are connected via the slide rail and groove, allowing the roller assembly to be assembled on the fixed bracket. A button is also connected to the PCB board, protruding from the bracket cover. A boss is located at the bottom of the frame, contacting the button. When the roller is pressed down, the roller and roller bracket move downwards together, and the boss at the bottom of the roller bracket presses the button, generating a switch signal.

[0013] The aforementioned new type of 360-degree roller switch also has a limit post at the bottom of the frame.

[0014] The redesigned roller structure of this utility model achieves gear adjustment through the cooperation of balls and corrugated teeth, providing a good feel and gear perception, applicable to multiple projects, with good versatility and high stability. Attached Figure Description
