Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical operating devices. Specifically, the present invention relates to a manipulation device. Background Art

[0002] A game controller is a common component of an electronic game device. By manipulating the joystick or buttons of the game controller, etc., the control of the game virtual character can be achieved. In the early days, the game controller mainly used the cross direction keys for direction control and sent action instructions through function buttons.

[0003] With the upgrading of game device hardware, modern game controllers have added analog joysticks (which can control both direction and perspective at the same time). The analog joystick can input control signals through the shaking of the joystick, and the output signal can achieve 360° controllability. Especially in AR or VR games, the analog joystick can provide users with a convenient manipulation experience.

[0004] However, there are also various problems with existing joysticks. For example, when the joystick is shaken, the control of the shaking force of the joystick is mainly completed through the force area brought by the user's arm. Due to the uncontrollability of the user's arm force and the shaking resistance of the joystick itself, it will bring a poor user experience to the user. Summary of the Invention

[0031] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present invention or its application or use.

[0033] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0034] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] Referring to Figure 1 , the present invention discloses a control device, comprising:

[0037] A rocker 1, a support part 2, a magnetic component 3 and a coil component 4, wherein the rocker 1 can rotate along the support part 2; the coil component 4 is arranged in an arc shape, the inner surface of the arc faces the rocker 1, and the magnetic component 3 is arranged at one end of the rocker 1 close to the coil component 4;

[0038] The coil component 4 is configured to be able to conduct an electrical signal, and a mutual force is generated between the coil component 4 and the magnetic component 3.

[0039] The support part 2 can be a rotating shaft, and the rocker 1 rotates along the axis of the support part 2; the support part 2 can also be a universal shaft, and the rocker 1 rotates in any direction along the center of the universal shaft of the support part 2.

[0040] Generally, the rocker 1 is manipulated by a user to rotate along the support part 2. However, due to the relatively large weight of the rocker 1 or the relatively large rotational resistance between the rocker 1 and the support part 2, it may cause inconvenience to the user. In the present invention, the magnetic component 3 is arranged at one end of the rocker 1 close to the coil component 4, and the mutual force between the magnetic component 3 and the coil component 4 is used to increase the driving force for the rotation of the rocker 1. Moreover, by adjusting the magnitude of the current in the coil component 4, the force between the magnetic component 3 and the coil component 4 can be further adjusted, improving the user's manipulation experience.

[0041] In addition, sometimes when the user manipulates the support part 2 to rotate, a certain sense of damping is required to bring a more realistic manipulation experience. By adjusting the direction of the current in the coil component 4 to generate a mutual force between the magnetic component 3 and the coil component 4, the sense of damping during the rotation of the support part 2 can be increased. Further, the force between the magnetic component 3 and the coil component 4 can be further adjusted by adjusting the magnitude of the current in the coil component 4, improving the user's manipulation experience.

[0042] Furthermore, the coil component 4 is arranged in an arc shape, and the inner surface of the arc faces the rocker 1. In this way, during the rotation of the rocker 1 driving the magnetic component 3, a relatively close distance can always be maintained between the magnetic component 3 and the coil component 4, so that a strong mutual force can always be maintained between the magnetic component 3 and the coil component 4, bringing a long-term continuous good experience to the user.

[0043] Optionally, the center of the arc of the coil assembly 4 coincides with the center of rotation of the rocker 1. The center of rotation of the rocker 1 can be the center of the support portion 2. When the center of the arc of the coil assembly 4 coincides with the center of rotation of the rocker 1, it can be ensured that during the process of the rocker 1 driving the magnetic assembly 3 to rotate, the distance between the magnetic assembly 3 and the coil assembly 4 can always be the same. See Figure 2 , that is to say, during the rotation of the magnetic assembly 3, the distance a between the magnetic assembly 3 and the coil assembly 4 can always remain unchanged. In this way, the magnetic field B generated by the magnetic assembly 3 will always be perpendicular to the coil assembly 4, providing a strong and stable acting force between the magnetic assembly 3 and the coil assembly 4.

[0044] Optionally, see Figure 1 , the coil assembly 4 is symmetrically arranged along the A-A plane. The A-A plane is arranged along the arc axis of the coil assembly 4 and passes through the center of rotation of the rocker 1 and the center of the coil assembly 4. In this way, during the process of the rocker 1 driving the magnetic assembly 3 to rotate, the same swing amplitude can be achieved on both sides of the A-A plane, and it can be ensured that the acting forces of the coil assembly 4 on the magnetic assembly 3 at symmetrical positions on both sides of the A-A plane are the same, ensuring the symmetrical operation amplitude of the operating device.

[0045] Optionally, the magnetic assembly 3 includes a central magnet 31 and at least one side magnet 32. The magnetization directions of the central magnet 31 and the side magnet 32 can intersect or be perpendicular to form a Halbach magnetic assembly, which greatly increases the magnetic field strength of the magnetic assembly 3, brings a stronger interaction force between the coil assembly 4 and the magnetic assembly 3, and improves the operating efficiency and operating experience of the operating device.

[0046] Optionally, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , the central magnet 31 can be columnar. One end of the columnar central magnet 31 is fixedly connected to the rocker 1, and the other end of the columnar central magnet 31 is frustum-shaped.

[0047] Specifically, the central magnet 31 can be cylindrical or prismatic. The prismatic shape can be a triangular prism, a quadrangular prism, a pentagonal prism or a hexagonal prism. The present invention does not limit this.

[0048] When the central magnet 31 is cylindrical, the connection between the cylindrical central magnet 31 and the rocker 1 can be welding or bonding. Both welding and bonding can ensure the firm connection between the central magnet 31 and the rocker 1. Setting the other end of the cylindrical central magnet 31 as a frustum shape can not only play a good role in magnetic focusing but also improve the smoothness of the other end of the cylindrical central magnet 31.

[0049] In addition, the other end of the cylindrical central magnet 31 can also be set as an arc surface, which can also play a good role in magnetic focusing and improve the smoothness of the cylindrical central magnet 31 at the same time.

[0050] Optionally, referring to Figure 6 and Figure 7 , Figure 6 the magnetization direction of the central magnet 31 in a is parallel to the axial direction of the cylindrical central magnet 31, Figure 6 and the magnetization direction of the side magnet 32 in b is perpendicular to the axial direction of the cylindrical central magnet 31. In this way, the magnetic field line direction as shown in Figure 7 can be formed. The magnetic field lines of the side magnet 32 facing the central magnet 31 are connected to the downward magnetic field lines of the central magnet 31, forming a strong magnetic field towards the coil assembly 4, which provides a guarantee for the strong interaction force between the coil assembly 4 and the magnetic component 3.

[0051] Optionally, the connection method between the central magnet 31 and the side magnet 32 can be welding or bonding. When the central magnet 31 and the side magnet 32 are connected by welding, it can not only ensure the connection stability between the two but also form a continuous and stable magnetic circuit, ensuring the continuity and stability of the magnetic circuit of the magnetic component 3. When the central magnet 31 and the side magnet 32 are connected by bonding, it can also ensure the connection stability between the two, and the operation is convenient and the cost is low.

[0052] Optionally, the number of the side magnets 32 can be one, two, three, four, five or six. When the number of the side magnets 32 is one, it can be a circular ring magnet. Referring to Figure 3 and Figure 4 , in a specific implementation manner, the number of the side magnets 32 is four, and the size of each side magnet 32 is the same, all of which are structures similar to a quarter ring. The four side magnets 32 surround the central magnet 31 and are connected to each other, and can be welded or bonded in pairs. The central magnet 31 and the multiple side magnets 32 around it form a compact structure of the magnetic component 3, and jointly generate a strong magnetic field, ensuring the magnetic field strength and stability of the operating device.

[0053] Optionally, referring to Figure 5 , chamfers may be provided at the edges of the side magnet 32. The chamfers may be arc chamfers, or may be chamfers formed by one or more inclined surfaces to approximate an arc shape. The setting of the chamfer structure not only facilitates the arrangement and extension of the magnetic force lines of the side magnet 32, but also avoids stress concentration at the edges of the side magnet 32, thereby improving the service life of the side magnet 32.

[0054] Optionally, it further includes a housing (not shown in the figure), and both the support portion 2 and the coil assembly 4 are fixedly connected to the housing.

[0055] The fixed connection between the support portion 2 and the housing can ensure the stability of the support portion 2 and provide stable support for the rotation of the rocker 1; while the fixed connection between the coil assembly 4 and the housing can provide stable structural support for the coil assembly 4, and can form a relatively fixed structure with the support portion 2 to ensure the relative position between the magnetic assembly 3 and the coil assembly 4 and the strong interaction force therebetween.

[0056] Optionally, referring to Figure 1 and Figure 2 , the operating device further includes a mating portion 5. The mating portion 5 may be an iron core or a magnet, and the mating portion 5 is located in the middle of the coil assembly 4.

[0057] The coil assembly 4 may be a toroidal coil with a hollow structure. The mating portion 5 is disposed in the hollow structure of the coil assembly 4 and is connected to the inner side of the coil assembly 4; alternatively, the mating portion 5 may also be fixedly connected to the housing.

[0058] When the mating portion 5 is an iron core, the mating portion 5 can generate a strong attractive force F on the magnetic assembly 3. Whether the coil assembly 4 is energized or not, the rocker 1 and the magnetic assembly 3 can automatically return to the equilibrium position under the gravitational action of the mating portion 5. Moreover, when the coil assembly 4 is energized, the iron core can also enhance the magnetic field generated by the coil assembly 4; when the mating portion 5 is a magnet, the polarities of the sides of the mating portion 5 and the magnetic assembly 3 close to each other may be opposite. In this way, after the rocker 1 and the magnetic assembly 3 rotate by a certain angle, the mating portion 5 can generate a strong attractive force F on the magnetic assembly 3. Whether the coil assembly 4 is energized or not, the rocker 1 and the magnetic assembly 3 can automatically return to the equilibrium position under the gravitational action of the mating portion 5, and the operation is flexible and simple, and the control is precise.

[0059] The present invention also discloses a game terminal, and the game terminal includes the operating device described above.

[0060] The control device of the present invention can be used as an interaction terminal for AR or VR games, such as a high-quality handle with vibration feedback function, which can bring a better control experience to users.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
