Description

Technical Field

[0001] This utility model relates to a backrest for an earthquake simulation device, belonging to the technical field of backrests for simulation devices. Background Technology

[0002] Earthquakes are dangerous natural disasters, and experiencing an actual earthquake can pose a significant risk to people's lives. With the development of VR technology, immersive experience devices based on VR technology have emerged. Some of these devices can simulate the dangers and effects of earthquakes. Users can personally experience the process of violent shaking from weak vibrations. Furthermore, guided by the VR scenario, they can learn the correct measures to take during an earthquake. When users wear VR glasses, the platform of the experience device shakes in accordance with the content played within the VR device. When the shaking reaches a certain intensity, users may experience injury or other accidents due to loss of balance.

[0003] Therefore, a device is needed to protect users' safety while using the experience equipment. Simultaneously, the safety of all users should be guaranteed when multiple users are using the same device, and the experience should not be negatively affected by the protective device. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1. As... Figures 1-4 As shown, a backrest for an earthquake simulation device includes a mounting device 1, a support device 2, and a protective device 3.

[0021] Mounting device 1 is fixed to the demonstration platform of the earthquake simulation device. Mounting device 1 consists of a mounting frame 101, an isolation plate 102, and a fixing flange 103. The mounting frame 101 is a single unit, with a cuboid structure at its center. Mounting columns extend downwards from both ends of one long side of the cuboid, and another mounting column extends downwards from the midpoint of the other long side. The downward extension distance of the mounting columns is uniform. A fixing flange 103 is installed at a distance from the bottom of each mounting column. The connection between the mounting column and the demonstration platform forms a triangle, effectively maintaining the stability of the backrest when subjected to forces from various directions.

[0022] A partition plate 102 is provided on one side of the long side of the mounting bracket 101 extending from the two columns. The partition plate 102 can be a flat plate or a shell installed on the outside of the mounting bracket 101. The partition plate 102 can improve the appearance of the mounting bracket 101, and when the partition plate 102 is a shell installed on the outside of the mounting bracket 101, it can reduce dust accumulation on the mounting bracket 101, thus reducing cleaning time.

[0023] The mounting bracket 101 above the mounting point of the isolation plate 102 is connected to the mounting bracket 101 on the other side at a certain tilt angle. The tilt angle is 40°-45°, and 45° is used in this embodiment. This also reduces material consumption and costs while strengthening the overall structure of the mounting bracket 101.

[0024] The three mounting columns below the mounting bracket 101 connect to the demonstration platform of the earthquake simulation device. A fixing flange 103 is provided at the connection point. The fixing flange 103 has fixing bolt holes on its inner side, and four reinforcing ribs connect the fixing flange to the mounting bracket 101. The mounting bracket 101 is bolted to the demonstration platform via the bolt holes on the fixing flange 103. The fixing flange 103 increases the mounting bracket 101's ability to withstand loads in all directions.

[0025] In this embodiment, the demonstration platform of the earthquake simulation device is provided with fixing holes corresponding to the positions of the mounting columns, and screw holes corresponding to the fixing flange 103 are provided around the top of the fixing holes. The bottom of the mounting column extends a certain distance below the fixing flange 103. The bottom of the mounting column can be placed inside the fixing holes. The screw holes around the fixing holes can cooperate with the fixing flange 103 to fix the mounting bracket 101 to the demonstration platform of the earthquake simulation device.

[0026] The support frame extends downwards from the midpoint of the mounting bracket 101, with the long side of the mounting column extending outwards by a distance. The support frame can be used to fix the backrest 201 by welding. There are six welding positions: the four ends of the rectangular mounting bracket 101 and the midpoints of two long sides. The support device 2 includes the backrest 201 and sponge pads 202. The backrest 201 has three backrest areas. The backrest 201 is distinguished by recesses and the sponge pads 202 installed in the backrest areas; the backrest 201 is a single unit. Three sponge pads 202 are provided on the front of the backrest 201, and the back of the backrest 201 is welded to the mounting bracket 101. The vertical welding position of the backrest 201 is at the midpoint of the backrest area.

[0027] The sponge pad 201 does not completely cover the backrest area. The backrest 201 has three pairs of mounting holes 302 on both sides of the backrest area, with one pair at each of the top, middle, and bottom ends of the backrest 201. There are a total of 18 mounting holes 302 on the backrest 201.

[0028] Mounting bracket 101 has mounting plates 301 connected to its two vertical welding ends. The top of mounting plate 301 is welded to mounting bracket 301 and one side of mounting plate 301 is welded to the back of backrest 201.

[0029] The protective device 3 consists of a mounting bracket 101, mounting holes 302, and safety belts. The safety belts are bolted to the mounting bracket 101, positioned between a pair of mounting holes 302. A total of nine safety belts are installed on the backrest 201. The safety belts can pass through the mounting holes 302 to reach the front of the backrest 201.

[0030] When participants enter the earthquake simulation device's demonstration platform, they must first go to the designated location to put on their safety belts and wait for instructions from staff before putting on the VR devices. Once all participants are ready, the earthquake simulation device is activated. During operation, the demonstration platform will shake in various directions according to the images played on the VR devices. The backrests provide support for the participants, offering directional support through the backrests and safety belts as the platform shakes. This protects participants from falls and injuries caused by platform shaking, as well as from poor viewing experiences.

[0031] The seat belts can be worn in three ways: all three seat belts are set horizontally, or the two upper seat belts are connected in a cross manner and the lower seat belt is set horizontally.

[0032] When the demonstration platform tilts backward, the safety belt only restricts the user's sliding to the left and right. The main support for the user is the backrest of the earthquake simulation device, and the force exerted on the backrest is backward. When the demonstration platform tilts to the left or right, the safety belt serves as the user's main support point. The user can maintain their balance using the safety belt. In this case, the force exerted on the backrest is to the left or right. When the demonstration platform tilts forward, the safety belt serves as the user's main support point, and the force exerted on the backrest is forward.

[0033] In this embodiment, the earthquake demonstration uses a head-mounted VR device to simulate earthquake visuals, and the demonstration platform of the earthquake simulation device shakes to create a complete demonstration. This can, to a certain extent, recreate the movement and sensations of people during an earthquake.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
