The multidirectional input device is widely applied in the field of VR devices, UAV controlling, etc. The multidirectional input device generally includes a housing, a rocker arm, a stick, an elastic member, and other members. The rocker arm is driven to rotate by the rotation of the stick, to realize the output of rotation. An unsymmetrical pressure is loaded on the elastic member and the energy is stored when the stick rotates, the elastic member suffers an unsymmetrical pressure and deflects, and the end part of the side that suffers the unsymmetrical pressure abuts against the rocker arm as a support point. During the rotation of the stick, the support point switches among each of the rocker arms. Since there are large gaps between rocker arms, the elastic member will throb during the deflection process, and transmit the throbbing to the stick, affecting the operating feeling.

In technical solutions of the present application, the multidirectional input device includes a housing 100, an operating body 200, a rocker arm member 300, a reset member 400 and a first pressing part 500. A chamber is provided inside the housing 100, and the housing 100 is provided with an opening communicating with the chamber. The operating body 200 is rotatably mounted in the chamber for an inclination operation, an end of the operating body 200 extends out of the chamber from the opening, an operating part 700 is provided at a lower end of the operating body 200, and a lower end face of the operating part 700 is circular. The rocker arm member 300 is provided in the chamber and can rotate in the chamber, the operating body 200 is drivingly connected to the rocker arm member 300. The inclination operation of the operating body 200 can drive the rotation of the rocker arm member 300. By connecting the rocker arm member 300 with devices such as potentiometers, the position of the rocker arm can be detected, and the signal can be input by tilting the operating body 200. The reset member 400 is also provided in the chamber, and is elastically connected to the operating body 200. When at an initial position, an upper end face of the reset member 400 that faces towards the opening abuts against the lower end face of the operating part 700. When the operating body 200 inclines, the operating part 700 can apply an elastic force to the reset member 400 to store energy. When the external force is unloaded, the reset member 400 can propel the operating part 700 to move, realizing the reset movement of the operating body 200. The first pressing part 500 is provided at the rocker arm member 300, and extends towards the reset member 400. Thus, when the operating body 200 inclines, the reset member 400 deflects, the edge of the operating part 700 abuts against the upper end face of the reset member 400, and the edge of the upper end face of the reset member 400 will abut against the first pressing part 500 as a support. Since the lower end face of the operating part 700 is circular, the edge of the lower end face will always touch the reset member 400 during the rotation of the operating part 700, and the edge of the upper end face of the reset member 400 is always supported by the first pressing part 500, in other words, the reset member 400 is always in contact with the operating body 200 and the first pressing part 500 during the movement of the reset member 400, thereby preventing the throbbing, improving the operating feeling of the multidirectional input device.

Specifically, as shown in FIG. 1 to FIG. 5, in order to realize a multidirectional input function, the multidirectional input device mainly includes a housing 100, an operating body 200, a rocker arm member 300, and a reset member 400. The housing 100 is a component that have a chamber inside, and the housing 100 is provided with an opening. In order to facilitate the manufacture, as shown in FIG. 2, the housing 100 could be separated into an upper housing and a lower housing. The upper housing has a top wall and a side wall disposed around the top wall, the top wall is provided with an opening, the top wall and the side wall enclose and form a chamber to contain other functional components. The lower part of the upper housing is open to facilitate the installation of other functional components. The lower housing is a platelike structure, the lower housing could be buckled to the position of the opening below the upper housing to enclose the chamber. Besides, in practical use, the lower housing can be used as a support for other components. Moreover, an operating body 200 is provided inside the housing 100. The operating body 200 may be a sticklike structure, the operating body 200 is rotatably accommodated in the chamber, and an end of the operating body 200 passes through the opening of the housing 100. Besides, an operating part 700 may be disposed on the lower end face of the operating body 200. The operating part 700 may be a cylinder or a frustum of a cone structure, the lower end face of the operating part 700 is a circular plane. A rocker arm member 300 is further provided inside the housing 100. The rocker arm member 300 is rotatably connected to the housing 100, the rocker arm member 300 may be drivingly connected to the operating body 200 by a transmission structure. The rotation of the rocker arm member 300 is driven by the swing of the operating body 200. A rotational potentiometer can be mounted to a rotating shaft of the rocker arm member 300. The movement of the operating body 200 drives the rocker arm member 300 to rotate, and then drives the rotational potentiometer to rotate, thereby triggering a signal change of a position sensor, and realizing the function of signal input. In this embodiment, two ends of the rocker arm member 300 extend downward to have a driving part, a contact plate spring is rotatably connected to the driving part, and a lower end of the contact plate spring abuts against a metal contact point which is provided on a bottom wall of the chamber. When the operating body 200 drives the rocker arm member 300 to rotate, the rocker arm member 300 drives the contact plate spring to slide on the metal contact point by the driving part. By measuring the potential difference between the metal contact point and the contact plate spring, the position determination of the contact plate spring can be realized, and then the binding of the position of operating body 200 and the potential signal is realized. Moreover, in order to support the operating body 200, a reset member 400 is further provided to the multidirectional input device. The reset member 400 is disposed in the chamber. The reset member 400 may be spring 420 or other elastic members. The reset member 400 may be disposed on the bottom wall of the chamber of the housing 100. The upper end face of the reset member 400 towards the opening abuts against the lower end face of the operating part 700. Thereby, when the operating body 200 is in a balanced position, that is, a middle position, the contact between the operating part 700 and the reset member 400 is a surface contact. When the operating body 200 inclines, the operating part 700 inclines, the edge of the lower end face of the operating part 700 abuts against the reset member 400. As the edge of the lower end face of the operating part 700 is continuous, the edge of the lower end face of the operating part 700 always abuts against the reset member 400 during the rotation of the operating body 200, that is, there is always a contact between the operating body 200 and the reset member 400. When the operating body 200 inclines, the operating body 200 presses against the reset member 400 downwards, the reset member 400 has an elastic deformation and stores energy. When the external force is unloaded from the operating body 200, the reset member 400 releases the elastic potential energy, propelling the operating body 200 to restore to a balanced state, realizing the reset of the operating body 200. When the operating body 200 inclines, then it is in an inclination position, and applies an unsymmetric pressure to the reset member 400. That is, the reset member 400 suffers an unsymmetric pressure, and the reset member 400 deflects. In the present embodiment, the first pressing part 500 is disposed on the rocker arm member 300, the first pressing part 500 may be disposed on an end face of the rocker arm member 300 towards the reset member 400. When the reset member 400 suffers an unsymmetric pressure and deflects, the edge of the upper end face of the reset member 400 may abut against the first pressing part 500 as a pivot. In the present embodiment, four first pressing parts 500 in total surrounding the reset member 400 are disposed on the rocker arm member 300. The first pressing part 500 is a supporting surface that extends along a peripheral surface of the reset member 400. In this way, when the operating body 200 rotates, the upper end face of the reset member 400 will always be in touch with the edge of the lower end face of the operating part 700, and the edge of the upper end face of the reset member 400 abuts against each of the first pressing parts 500 circularly. That is, the reset member 400 always touches the operating body 200 and the first pressing parts 500 during the rotating process, the throbbing of the reset member 400 is eliminated, thereby improving the operating feeling of the multidirectional input device.

Further, a lower surface of the first pressing part 500 is an arc-shaped surface or a plane surface, the lower surface extends along a circumference of the upper end face of the reset member 400. In order to further improve the operating feeling, the lower surface of the first pressing part 500 may be designed into an arc-shaped surface or a plane surface, and the lower surface extends along the circumference of the upper end face of the reset member 400 and towards the neighboring first pressing parts 500 on the two sides of the lower surface. By this design, the contact between the reset member 400 and the first pressing part 500 is a rolling contact during the deflecting process of the reset member 400, which prevents the relatively sliding between the reset member 400 and the first pressing part 500, and helps to reduce the friction when operating, thereby improving the operating feeling. In the present embodiment, the lower surface is an arc-shaped surface, in this way, the reset member 400 can switch between two neighboring first pressing parts 500 more fluently by adjusting the radian of the arc-shaped surface, operating feeling and user experience are improved thereby.

Further, the multidirectional input device includes a second pressing part 600, the second pressing part 600 is provided on the side wall of the chamber, and extends in a direction close to the reset member 400.

At least one of the first pressing part 500 and the second pressing part 600 abuts against a side surface of the reset member 400 that faces towards the opening during the movement process of the operating body 200.

The rocker arm member 300 includes an upper rocker arm 310 and a lower rocker arm 320 orthogonal to the upper rocker arm 310. The second pressing part 600 is disposed on two opposite ends of the upper rocker arm 310 and two opposite ends of the lower rocker arm 320, the first pressing part 500 is disposed between two neighboring second pressing parts 600.

As shown in FIG. 6, in order to further improve the operating feeling, the second pressing part 600 is provided to the multidirectional input device. The second pressing part 600 is disposed on the inner wall of the chamber of the housing 100, the second pressing part 600 may be a single independent part or a whole structure integrated to the housing 100, there is no limitation in specific here. The second pressing part 600 extends towards the reset member 400. In this way, when the operating body 200 inclines, the reset member 400 deflects, at least one of the first pressing part 500 and the second pressing part 600 abuts against the end face of the reset member 400 that faces towards the opening to support reset member 400. When the operating body 200 rotates, the reset member 400 moves synchronously, the first pressing part 500 and the second pressing part 600 abut against the reset member 400 circularly. In the present embodiment, the second pressing part 600 is provided in the housing 100. In other words, the supporting position of the reset member 400 during the deflecting process is added, and the distance between two neighboring supporting positions is shortened, the fluency of the reset member 400 switching between the supporting positions is improved thereby, the operating feeling is further improved.

As shown in FIG. 4 and FIG. 6, in the present embodiment, the rocker arm member 300 may be the combination of the upper rocker arm 310 and the lower rocker arm 320. The upper rocker arm 310 and the lower rocker arm 320 are orthogonally disposed with each other and are rotatably connected to the housing 100. The first pressing part 500 may be disposed on two ends of the upper rocker arm 310 and two ends of the lower rocker arm 320. This is to say, the first pressing part 500 forms four supporting positions on the rocker arm member 300, the second pressing part 600 may be disposed between two neighboring first pressing parts 500. This is to say that the second pressing part 600 also forms four supporting positions. Eight touching positions in total are formed on the housing 100 and the rocker arm member 300, the touching positions are disposed surrounding the reset member 400, the reset member 400 switches from these touching positions when rotates. By setting like this, the distance between two neighboring pressing parts is shortened. Besides, by adjusting the relative height difference between each of neighboring pressing parts according to the structure and the shape of the reset member 400, the fluency of the reset member 400 switching between each of the pressing parts can be improved, and then the operating feeling is further improved.

Further, there is an arc transition connecting a bottom surface and a peripheral surface of the operating part 700. As shown in FIG. 6, the arc transition is formed between the bottom surface of the operating part and the peripheral surface of the operating part. In this way, the stress concentration at the edge of the operating part 700 will be greatly reduced, which helps to improve the service life. Besides, the size of the arc transition can be designed according to the track of the inclination of the operating body 200, which changes the sliding between the operating body 200 and the reset member 400 into rolling, helps to reduce the abrasion.

Further, a stopping part 800 is provided on the operating body 200. The stopping part 800 is disposed on a side surface of the operating part 700 away from the opening, and the stopping part 800 extends in a direction away from the operating part 700. Specifically, as shown in FIG. 6, the stopping part 800 is disposed on the side surface of the operating body 200 that faces towards the bottom wall of the chamber, and extends downwards. Thus, when pressing the operating body 200, the stopping part 800 can restrict the pressing stroke of the operating body 200 effectively, prevent the failure of the reset member 400 caused by an excessive pressing stroke. Besides, a pressing switch may be provided on the bottom wall of the chamber. By pressing the operating body 200, the operation to the pressing switch by the stopping part 800 can be realized, the functional diversity of the multidirectional input device can be increased.

Further, the reset member 400 includes a spring 420 and a pressing plate 410. The spring 420 is provided in the chamber, and extends in a direction close to the opening. The pressing plate 410 is provided on an end of the spring 420 towards the opening, the spring 420 presses the pressing plate 410 against the operating body 200. During the movement process of the operating body 200, the first pressing part 500 abuts against a side surface of the pressing plate 410 towards the opening.

As shown in FIG. 3 and FIG. 7, the reset member 400 includes a pressing plate 410 and a spring 420. The spring 420 is disposed on the bottom wall of the chamber, and extends towards the opening. The pressing plate 410 is disposed on the upper end face of the spring 420, the pressing plate 410 is pressed against the operating body 200 by the elasticity of the spring 420. During the rotating process of the operating body 200, the lower end face of the operating body 200 abuts against the upper end face of the pressing plate 410, the pressing plate 410 suffers an unsymmetrical pressure from the operating body 200 and inclines, then the spring 420 compresses downwards. The edge of the pressing plate 410, which is relative to the position of the operating body 200 that suffers the unsymmetrical pressure, will abut against the first pressing part 500. When the external force is unloaded, the deformation of the spring 420 is eliminated, the spring 420 propels the pressing plate 410 to adjust the operating part 700 to a balanced state. The resultant force of each of the force brought by the spring 420 to the pressing plate 410 points straight upwards, the operating body 200 is kept at this position thereby. In order to improve the operating feeling, the pressing plate 410 may be set as a round structure part. In this way, when the pressing plate 410 swings, the distance between the supporting position of the edge of the pressing plate 410 and the position of the operating body 200 that suffers an unsymmetrical pressure is constant, and the constancy of the compression amount of the spring 420 is ensured, the consistency of the elastic force of the spring 420 is ensured while operating, thereby the operating feeling is improved.

Further, a rib is provided on a lower end face of the pressing plate 410, the rib extends along a circumference of the lower end face of the pressing plate 410 to restrict the spring 420 to an inner side of the rib. In order to improve the stability of the movement of the reset member 400, a rib may be disposed on the lower end face of the pressing plate 410. The rib may be disposed on the edge of the lower end face of the pressing plate 410 and may extend along the circumference of the pressing plate 410. The upper end face of the spring 420 abuts against the inner side of the rib. By setting the rib, the restriction for the lateral displacement of the spring 420 is realized, thus preventing a happening of the relative displacement between the pressing plate 410 and the spring 420 when the reset member 400 moves, thereby the stability of the movement of the reset member 400 is ensured.

Further, the spring 420 is a conical spring, an outer diameter of the spring 420 increases gradually from a bottom wall of the chamber to the pressing plate 410. Compared to an ordinary spring, the height of the conical spring is reduced when the spring compresses in the precondition of the same performance, which helps to reduce the overall height of the multidirectional input device. Besides, since the conical spring can provide more lateral stability, so it has less bending tendency when deflects, thus the relative horizontal of the upper end face of the spring 420 is ensured, which helps to improve the operating feeling.

The present application further provides a controller. The controller includes a main frame and the multidirectional input device, the multidirectional input device may be provided on the main frame for signal input, the specific structure of the multidirectional input device refers to the embodiments above.
