Description

Technical Field

[0001] The utility model relates to the technical field of virtual reality equipment, in particular to a VR swing mechanism and a VR somatosensory device. Background Art

[0002] The mechanically driven lifting device of the existing virtual reality equipment usually sets cylinders on both sides of the play seat as the lifting drive device, so the lifting height is equal to the telescopic stroke of the push rod. Therefore, the lifting stroke will be limited by the cylinder push stroke and cannot be lifted significantly. In a limited space, it only supports 0mm-400mm lifting stroke, which makes the user's immersive experience not very strong. In addition, the symmetrically arranged lifting structure not only reduces the utilization rate of the maintenance and repair space, but also increases the production cost of the device. Moreover, due to the high center of gravity of the lifting mechanism, when the seat is raised, the stability and safety of the equipment operation will be reduced.

[0003] Therefore, a swing mechanism is needed which can realize large lifting and swinging by utilizing a small space. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a VR swing mechanism, which can be used to enhance the user's swinging experience in the vertical direction.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A VR swing mechanism comprises a support seat, a swing arm and a lifting assembly, wherein one end of the lifting assembly is rotatably connected to the support seat, and an output end thereof is rotatably connected to the swing arm. One end of the swing arm is rotatably connected to the support seat, and the lifting assembly is actuated to cause the swing arm to swing up and down away from one end of the support seat.

[0007] In one embodiment, the lifting assembly includes one or more lifting cylinders, the bottom end of the lifting cylinder is hingedly arranged on the support seat, and the output end of the lifting cylinder is connected between the two ends of the swing arm.

[0008] In one embodiment, the lifting assembly is connected to the swing arm near the support seat.

[0009] In one embodiment, it further includes one or more traction members and a mounting portion for mounting a seat, wherein the mounting portion is rotatably disposed at one end of the swing arm, and the traction member is respectively connected to the support seat and the mounting portion.

[0010] In one embodiment, the traction member is configured as one of an elastic member, a flexible member, and a rigid connecting arm.

[0011] In one embodiment, the traction member is a rigid connecting arm, and further includes a plurality of support members respectively connected to the traction member, one end of the support member is hingedly disposed on the support seat, and the other end is hingedly connected to the middle portion of the rigid connecting arm.

[0012] In one embodiment, the support member includes one of a gas spring support rod and a hydraulic support rod.

[0013] In one embodiment, the traction member is a rigid connecting arm, and the swing arm and the traction member have the same length.

[0014] In one embodiment, the height difference between the traction member and the swing arm is greater than 0.

[0015] The second aspect of the utility model further proposes a VR somatosensory device, comprising a VR swing mechanism and a play seat as described in any one of the above items, wherein the play seat is suspended at one end of the swing arm away from the support seat.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The utility model arranges a lifting assembly and a swing arm on a support seat, and the lifting assembly is connected to the swing arm. Since the fulcrum of the lifting assembly on the swing arm is located in the middle of the swing arm and the swing arm is rotatably connected to the support seat, the swing arm and the lifting assembly form a force-consuming lever. When the lifting assembly is actuated, the swing arm can be lifted and swung to a greater extent away from the end of the support seat, thereby achieving a large swing effect in a smaller space.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example 1

[0029] See also Figures 1 to 5The utility model discloses a VR swing mechanism, including a support seat, a swing arm and a lifting assembly, one end of the lifting assembly is rotatably connected to the support seat, and its output end is rotatably connected to the swing arm, one end of the swing arm is rotatably connected to the support seat, and the lifting assembly is actuated to make the swing arm swing up and down away from one end of the support seat. A rotatable mounting portion 5 is provided at one end of the swing arm, and the mounting portion 5 is used to fix the play seat. In this embodiment, preferably, the mounting portion 5 is an integrally formed mounting plate. The support seat 1 includes a base plate and a steel frame, and the swing arm 2, the traction member 3, the lifting assembly 4, and the mounting portion 5 are all arranged on the steel frame, ensuring that the mounting portion 5 and one side of the steel frame remain balanced and are not easy to tip over. At the same time, the lifting assembly 4 is hidden in the steel frame, which can also effectively improve the appearance of the product. The lifting assembly 4 includes one or more lifting cylinders, the bottom end of the lifting cylinder is hingedly arranged on the support seat 1, and the output end of the lifting cylinder is hingedly connected to the swing arm 2.

[0030] In this embodiment, the lifting assembly 4 is hingedly connected to the lower end of the swing arm 2. One end of the swing arm 2 is hingedly connected to the support seat 1, and the other end is hingedly connected to the mounting portion 5. The rotational connection between the swing arm 2 and the support seat 1 is a fulcrum, and the swing arm 2 forms a laborious lever. When the lifting assembly 4 is pushed upward, the output end of the lifting cylinder pushes out to lift the swing arm 2, and the mounting portion 5 at the end of the swing arm 2 moves upward more significantly. In this process, the traction member 3 continuously applies a pulling force to the mounting portion 5, so that the posture of the hinged mounting portion 5 remains unchanged to prevent it from turning downward. When the lifting assembly 4 descends, the swing arm 2 is simultaneously downward, and the mounting portion 5 descends accordingly. The rising and falling of the lifting assembly 4 increases the lifting and lowering range of the mounting portion 5. At the same time, since the mounting portion 5 is rotatably connected to the swing arm 2, during the lifting process, the mounting portion 5 will swing around the hinge axis, providing users with a more exciting play experience.

[0031] In this embodiment, the lifting assembly 4 is preferably hinged to the side of the swing arm 2 close to the support seat 1. Specifically, the distance between the fulcrum of the lifting assembly 4 on the swing arm 2 and the support seat 1 is smaller than the distance between the fulcrum and the mounting portion 5, ensuring that the structure forms a laborious lever, and the lifting cylinder performs a relatively small movement to enable the mounting portion 5 to achieve a relatively large up and down swing.

[0032] This embodiment preferably further includes one or more traction members 3, which are connected to the support seat 1 and the mounting portion 5 respectively. The traction member 3 is configured as one of an elastic member, a flexible member, and a rigid connecting arm. It can be understood that since the swing arm 2 and the mounting portion 5 are hinged, the traction member 3 is connected to the mounting portion 5 and applies tension, and multiple connection points ensure that the mounting portion 5 cannot rotate freely, ensuring that the posture of the mounting portion 5 during the lifting process remains relatively stable, thereby improving the experience of the playing user. Therefore, the elastic member, flexible member, and rigid connecting arm that can apply tension to the mounting portion 5 are all within the protection scope of the present utility model. The elastic member can be a spring, and the flexible member can be a metal chain, a soft rope, or other connector with easy-to-deform characteristics. The rigid connecting arm is a structure such as a connecting rod and a connecting plate with difficult-to-deform characteristics. The height difference at the connection between the traction member 3, the swing arm 2, and the mounting portion 5 is greater than 0. By staggering the heights of the traction member 3 and the swing arm 2 on the mounting portion 5, when the traction member 3 and the swing arm 2 are connected to the mounting portion 5, the mounting portion 5 can be locked by pulling forces in at least two directions to prevent the mounting portion 5 from flipping over, so that the posture of the mounting portion 5 remains unchanged during the up and down swinging process. In another embodiment, the position of the traction member 3 can also be set on the lower side of the swing arm 2.

[0033] Furthermore, the traction member 3 is a rigid connecting arm, and further comprises a plurality of support members 6, the bottom ends of the support members 6 are hingedly arranged on the support seat 1, and the output ends of the support members 6 are hingedly connected to the traction member 3. The support members 6 can reduce the pressure on the lifting cylinder, provide support force for the traction member 3, and thus more efficiently lift the swing arm 2 and the mounting portion 5. Figure 2 As shown, a support member 6 is provided at the bottom of each traction member 3. When the support member 6 is in motion, the traction member 3 is lifted up, so that the mounting portion 5 swings up and down.

[0034] Specifically, the support member can be one of a gas spring support rod, a hydraulic support rod, and an elastic member. The gas spring support rod, the hydraulic support rod, and the elastic member can provide support force while making the movement process of the traction member 3 softer and smoother, so as to improve the user experience. When a gas spring or hydraulic support rod structure is used, the support member 6 is located at the lower side of the traction member 3 to provide thrust for the traction member 3; when an elastic member is used as the support member 6, the support member 6 is located at the upper side of the traction member 3 to provide tension for the traction member, thereby achieving the effect of balancing the weight of the traction member 3. The above selection is only the preferred support rod in this embodiment, and other support rods that can achieve the support effect are also within the protection scope of this application.

[0035] In one embodiment, when the lifting assembly 4 is not working, the swing arm 2 is horizontally arranged. It is understandable that the traction member 3 is also kept horizontally arranged, so that when the lifting assembly 4 starts to work, it starts to push upward from a horizontal posture, and the process of pushing the swing arm 2 is smoother.

[0036] In one embodiment, the traction member 3 is a rigid connecting arm, and the swing arm 2 and the traction member 3 have the same length.

[0037] The utility model arranges a lifting component 4 and a swing arm 2 on a support seat 1, and the lifting component 4 is connected to the swing arm 2. Since the fulcrum of the lifting component 4 on the swing arm 2 is located in the middle of the swing arm 2, a force-consuming lever is formed. When the lifting component 4 is in motion, the mounting portion 5 located at the end can swing up and down with a greater amplitude, thereby achieving a large-amplitude swing effect in a smaller space; secondly, the swing arm 2 and the traction member 3 are hinged to the mounting portion 5, so that when the mounting portion 5 swings with the swing arm 2, its attitude angle relative to the ground remains unchanged, and the mounting portion 5 moves up and down as a whole.

[0038] Example 2

[0039] like Figure 5 As shown, the second aspect of the utility model also proposes a VR somatosensory device, including a VR swing mechanism as described in Example 1 and a play seat 7, wherein the play seat 7 is fixedly arranged at one end of the swing arm away from the support seat. In this embodiment, the play seat 7 is preferably installed in a hanging manner. The play seat 7 with a hanging arrangement can ensure that the user's posture always remains the same, thereby improving the user experience. It can be understood that the hanging arrangement is only the preferred installation method in this embodiment, and other installation methods are also within the protection scope of this application.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
