Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a magnetic knob controller. Background Art

[0002] A magnetic knob controller is an input device that combines rotation and pressing functions. Rotating the knob adjusts settings, while pressing it activates or locks the knob. A built-in magnetic sensor senses the knob's rotation angle and position, enabling precise control. This type of controller is widely used in consumer electronics, industrial equipment, and automotive applications to improve operational safety and precision.

[0003] The design feature of the magnetic knob controller lies in the protruding structure of its knob part. Although this design is convenient for holding in daily operation, it is also prone to accidental touches. False touches may inadvertently change the device settings, thereby affecting the user experience and the accuracy of the device functions. Utility Model Content

[0004] The utility model aims to provide a magnetic knob controller which can prevent accidental touch.

[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0006] A magnetic knob controller includes a controller body, the upper surface of which is provided with a groove, a knob shaft rotatably mounted within the groove, a knob cap sleeved on the outer surface of the knob shaft, an outer spline formed on the outer surface of the knob shaft, an inner spline formed on the inner wall of the knob cap, and the inner spline mating with the outer spline. A pressure plate is provided within the groove, a shoulder is provided at the bottom of the knob cap, a spring is provided within the groove, and the spring sleeved on the outer surface of the knob shaft, a plurality of sockets are provided on the lower surface of the pressure plate, and a plurality of rods are mounted on the upper surface of the shoulder, and the rods mating with the sockets.

[0007] It can be seen that through the setting of the external spline and the internal spline, when the knob cap is rotated, the knob shaft can be driven to rotate to achieve the purpose of control and adjustment. When the knob cap is rotated, it is necessary to press downward to drive the insertion rod to be pulled out from the inside of the socket before it can be rotated. When the rotation is completed and the knob cap is released, the knob cap can be pushed up under the elastic force of the spring, and the insertion rod can be reinserted into the socket, thereby achieving the purpose of locking the knob cap to prevent accidental touch.

[0008] Furthermore, a partition plate is provided inside the groove, and the partition plate is sleeved on the outer surface of the knob shaft, and the spring abuts against the lower surface of the partition plate. A limiting groove is provided on the inner wall of the groove, and a limiting slider is installed on the outer surface of the partition plate, and the limiting slider is provided in the limiting groove.

[0009] The partition plate prevents the bottom of the knob cap from directly contacting the spring, and through the setting of the limiting groove and the limiting slider, the partition plate can be limited so that it cannot rotate and can only be raised and lowered. Therefore, when the knob cap rotates, the torsion generated at its bottom will not act on the spring, causing its deformation and damage, thereby improving the service life of the spring.

[0010] Furthermore, the pressing plate is connected to the inner wall of the groove by screws.

[0011] Since the pressure plate is a detachable structure, it is convenient to replace accessories such as the knob cap, spring and separator when they are damaged.

[0012] Furthermore, a rubber pad is provided on the outer surface of the knob cap, and an anti-slip pattern is provided on the outer surface of the rubber pad.

[0013] The setting of rubber pads and anti-slip patterns can increase the friction between the hand and the knob cap, reduce the occurrence of hand slippage, and improve the user experience.

[0014] Furthermore, the number of jacks is greater than ten, and the multiple jacks are distributed in a coaxial array.

[0015] The number of jacks is related to the adjustment angle range of the knob shaft. The more jacks there are, the smaller the angle between two adjacent jacks is, and the higher the adjustment accuracy of the knob shaft is.

[0016] Furthermore, the outer surface of the spring is coated with anti-rust paint.

[0017] By applying anti-rust paint, the spring can be effectively isolated from contact with moisture in the air, thereby preventing oxidation and rust and increasing its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a magnetic knob controller includes a controller body 100. The upper surface of the controller body 100 is provided with a groove 101. A knob shaft 102 is rotatably mounted within the groove 101. A knob cap 103 is sleeved on the outer surface of the knob shaft 102. The outer surface of the knob shaft 102 is provided with an external spline 104. The inner wall of the knob cap 103 is provided with an internal spline 105, which is adapted to fit within the external spline 104. A pressure plate 106 is provided within the groove 101. A shoulder 107 is provided at the bottom of the knob cap 103. A spring 108 is provided within the groove 101 and sleeved on the outer surface of the knob shaft 102. A plurality of insertion holes 109 are provided on the lower surface of the pressure plate 106. A plurality of insertion rods 110 are mounted on the upper surface of the shoulder 107, which are adapted to fit within the insertion holes 109.

[0026] When in use, first press the knob cap 103 downward so that the shoulder 107 compresses the spring 108 and drives the insertion rod 110 to be pulled out of the hole 109. At this time, the knob cap 103 is released and can be rotated. Due to the limiting effect of the external spline 104 and the internal spline 105, the knob shaft 102 can be synchronously driven to rotate when the knob cap 103 rotates, thereby achieving the purpose of control and adjustment. When the rotation is completed and the knob cap 103 is released, the elastic force of the spring 108 can push the knob cap 103 up and reinsert the insertion rod 110 into the hole 109, thereby achieving the purpose of locking the knob cap 103 and preventing accidental touch from affecting the user experience and the accuracy of the device function. It is worth noting that the controller body 100 in this application is a common existing technology, so it will not be elaborated here.

[0027] Specifically, a partition plate 200 is provided inside the groove 101, and the partition plate 200 is sleeved on the outer surface of the knob shaft 102, and the spring 108 abuts against the lower surface of the partition plate 200. A limiting groove 201 is provided on the inner wall of the groove 101, and a limiting slider 202 is installed on the outer surface of the partition plate 200, and the limiting slider 202 is set in the limiting groove 201. The partition plate 200 prevents the bottom of the knob cap 103 from directly contacting the spring 108, and through the setting of the limiting groove 201 and the limiting slider 202, the partition plate 200 can be limited so that it cannot rotate and can only be raised and lowered. Therefore, when the knob cap 103 rotates, the torsion generated at its bottom will not act on the spring 108, causing it to deform and damage, thereby improving the service life of the spring 108.

[0028] Specifically, the pressure plate 106 is connected to the inner wall of the groove 101 through the screw 300. Since the pressure plate 106 is a detachable structure, it is convenient to replace accessories such as the knob cap 103, the spring 108 and the partition plate 200 when they are damaged.

[0029] Specifically, the outer surface of the knob cap 103 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip grooves. The setting of the rubber pad and the anti-slip grooves can increase the friction between the hand and the knob cap 103, reduce the occurrence of hand slippage, and improve the user experience.

[0030] Specifically, the number of jacks 109 is greater than ten, and multiple jacks 109 are distributed in a coaxial array. The number of jacks 109 is related to the adjustment angle range of the knob shaft 102. The more jacks 109 there are, the smaller the angle between two adjacent jacks 109, and the higher the adjustment accuracy of the knob shaft 102.

[0031] Specifically, the outer surface of the spring 108 is coated with anti-rust paint. The anti-rust paint can effectively isolate the spring 108 from contact with moisture in the air, thereby preventing oxidation and rusting and increasing its service life.

[0032] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
