[0032] Electronic products need to interact with users, and the ease of operation and comfort of input devices have a particularly significant impact on the user's experience. At present, for electronic devices such as computers and tablets, keyboards, mice, or handwriting tablets are generally used as input devices. When users need to zoom in or out on the interface or drag the progress bar, they often use the mouse to drag or the mouse wheel to scroll. However, after long-term use, the wrist holding the mouse will become sore, and in the long run it will also cause tendonitis and other pains.
[0033] In this regard, there are some vertically set joystick handles on the market. Users control the movement of the cursor by operating the joystick. Moreover, due to its vertical setting, the user's wrist does not touch the desktop and is not subjected to force. Even if used for a long time, it will not cause excessive strain on the user's hand. In order to meet the user's operating needs, the joystick also needs to be equipped with a roller. According to the survey, different users have different preferences for the location of the roller. Some users prefer to set the roller at the end of the joystick, while other users prefer to set the roller at the base of the joystick. No matter how the roller is set, it cannot take into account the preferences of different users.
[0034] In this regard, the present application proposes a dual-roller rocker device, by setting a first roller 310 on the base 100 and a second roller 410 at the end of the operating rod base 200. The user can use the first roller 310 located at the base 100 for operation, or use the second roller 410 located at the end of the operating rod base 200 for operation, thereby integrating the two operating modes to take into account users with different usage preferences.
[0035] Reference Figure 1The dual roller rocker device in the embodiment of the present application includes a base 100, an operating rod base 200, a first roller assembly 300 and a second roller assembly 400. The base 100 is the main structure of the dual roller rocker device, which is used to provide support for other components of the dual roller rocker device. The first end of the operating rod base 200 is hinged to the base 100, specifically using a ball-type hinge, so that the operating rod base 200 can swing at multiple angles. The user can control the electronic device by operating the operating rod base 200 to swing, such as controlling the movement of the cursor or viewing angle in the electronic device. The first roller assembly 300 is arranged on the base 100, and is provided with a first roller 310. The second roller assembly 400 is arranged on the operating rod base 200, and is provided with a second roller 410. The user can control by rotating the first roller 310 or the second roller 410, thereby meeting the use needs of users with different use preferences.
[0036] Specifically, refer to Figure 2 and Figure 3 The first roller assembly 300 includes a first roller 310, a first magnetic ring 320 and a functional mainboard 330. The first roller 310 is in a ring shape and is rotatably connected to the base 100. The operating rod base 200 extends from the center of the first roller 310, and the first roller 310 rotates around the operating rod base 200. The first magnetic ring 320 is connected to the first roller 310, and when the first roller 310 rotates, it can drive the first magnetic ring 320 to rotate together. The functional mainboard 330 is fixedly installed in the base 100 and can be magnetically induced by the first magnetic ring 320. When the first magnetic ring 320 rotates with the first roller 310, the Hall switch on the functional mainboard 330 can be triggered by the first magnetic ring 320, thereby converting the mechanical energy of the rotation of the first magnetic ring 320 into an electrical signal, and inputting the electrical signal into an external electronic device to complete the signal input.
[0037] Furthermore, the outer diameter of the middle portion of the operating rod base 200 is reduced, thereby reducing the interference between the outer wall of the operating rod base 200 and the base 100 when the operating rod base 200 swings, and facilitating the free swinging of the operating rod base 200 .
[0038] Furthermore, the base 100 is in the shape of a truncated cone or a prism, and its side surface is an inclined surface to obtain a better appearance, and additional buttons and knobs are provided on the side of the base 100 for easy operation by the user. A socket for connecting a data cable is provided on the back of the base 100, so as to form a wired connection with an external electronic device. It is easy to understand that a Bluetooth module can also be provided in the base 100, and the dual roller rocker device is wirelessly connected to an external electronic device through the Bluetooth module.
[0039] Furthermore, the base 100 is provided with a receiving cavity 110, which is cylindrical, and the first roller 310 and the first magnetic ring 320 both rotate in the receiving cavity. Thus, the receiving cavity serves to limit the first roller 310 and the first magnetic ring 320, preventing them from escaping from the receiving cavity, and reducing interference with the rotation of the first roller 310 and the first magnetic ring 320.
[0040] Furthermore, an extension portion 311 is provided on the top of the first roller 310, and the extension portion 311 extends laterally to cover the gap between the first roller 310 and the accommodating cavity, preventing external dust from entering the gap and increasing the friction resistance between the first roller 310 and the inner wall of the accommodating cavity, thereby improving the rotation smoothness of the first roller 310.
[0041] Furthermore, the surface of the extension 311 is provided with anti-skid stripes 3111, which can increase the friction between the extension 311 and the user's fingers, so that the user can more easily drive the first roller 310 to rotate. In this embodiment, the anti-skid stripes 3111 are a plurality of straight grooves distributed in a circular array around the rotation axis of the first roller 310. It is easy to understand that other shapes of anti-skid stripes 3111 can also be used to meet the anti-skid requirements, which will not be repeated here.
[0042] Furthermore, the first roller assembly 300 also includes a first bearing 340, which is arranged between the first roller 310 and the base 100, and can convert the sliding friction between the outer wall of the first roller 310 and the inner wall of the base 100 into rolling friction, thereby reducing the friction resistance between the two, so that the first roller 310 can rotate more smoothly, thereby improving the user's experience.
[0043] Specifically, a buckle is provided in the receiving cavity of the base 100, which is buckled with the outer wall of the first bearing 340 through the buckle; the outer wall of the first roller 310 is also provided with a buckle, which is buckled with the inner wall of the first bearing 340 through the buckle. Therefore, both the inner and outer sides of the first bearing 340 are limited and fixed by the buckle, preventing the connection between the first bearing 340 and the base 100 or the first roller 310 from being loosened.
[0044] Reference Figure 4 and Figure 5, the second roller assembly 400 includes a second roller 410, a second magnetic ring 420 and a button main board 430. The second roller 410 is in a ring shape and is rotatably connected to the second end of the operating rod base 200. The button main board 430 is fixedly connected to the operating rod base 200 and extends out from the center of the second roller 410. The second magnetic ring 420 is connected to the second roller 410, and when the second roller 410 rotates, it can drive the second magnetic ring 420 to rotate together. The button main board 430 and the second magnetic ring 420 are inductively coupled. When the first magnetic ring 320 rotates with the first roller 310, the Hall switch on the functional main board 330 can be triggered by the first magnetic ring 320, thereby converting the mechanical energy of the rotation of the first magnetic ring 320 into an electrical signal, and inputting the electrical signal into an external electronic device to complete the signal input.
[0045] Furthermore, the outer side of the second roller 410 may be provided with anti-skid stripes, which can increase the friction between the second roller 410 and the user's finger, so that the user can more easily drive the second roller 410 to rotate. The anti-skid stripes can be in the form of a plurality of equidistantly arranged straight grooves, or other anti-skid stripe patterns that can meet the anti-skid requirements, which will not be described in detail here.
[0046] Furthermore, the second roller assembly 400 also includes a second bearing 440, which is arranged between the second roller 410 and the operating rod base 200, and can convert the sliding friction between the outer wall of the second roller 410 and the inner wall of the operating rod 200 into rolling friction, thereby reducing the friction resistance between the two, so that the second roller 410 can rotate more smoothly, thereby improving the user's experience.
[0047] Specifically, the inner wall of the operating rod base 200 is provided with a buckle, which is buckled with the outer wall of the second bearing 440 through the buckle; the outer wall of the second roller 410 is also provided with a buckle, which is buckled with the inner wall of the second bearing 440 through the buckle. Therefore, both the inner and outer sides of the second bearing 440 are limited and fixed by the buckle, preventing the connection between the second bearing 440 and the operating rod base 200 or the second roller 410 from being loosened.
[0048] Furthermore, the second roller assembly 400 further includes a support frame 450 , through which the button main board 430 is connected to the operating rod base 200 , and the support frame 450 also serves to lift the button main board 430 to extend from the center of the second roller 410 .
[0049] Furthermore, a key 431 is provided on the top of the key main board 430 for user operation. In this embodiment, five keys 431 are provided and are distributed in a circular array around the center of the key main board 430. It is easy to understand that the number and location of the keys 431 can be selected according to actual needs. The user can input an electrical signal by pressing the key 431, thereby increasing the diversity of input methods.
[0050] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments.
