[0001] This utility model relates to the field of cinema equipment technology, and in particular to a rocking chair motor swing angle mechanical limit device. Background Technology
[0002] Compared to traditional cinemas, 4D cinemas use specific technologies to allow viewers not only to see and hear the film content, but also to experience various physical effects that match the film's plot, such as swaying, vibration, spray, and wind. The 4D cinema rocking chair is an advanced cinema seat that combines visual, auditory, and kinematic experiences, aiming to provide a more immersive viewing experience.
[0003] Existing rocking chairs typically use a motor drive to rock the chair. During the rocking process, the swing angle of the motor is controlled by turning the motor on and off. Since there is no limit to the swing angle, if the user is not fully attached to the rocking chair, the swing amplitude is too large, causing the user to fall off the rocking chair, resulting in poor safety. In view of this, this solution proposes a mechanical limit device for the swing angle of the rocking chair motor to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] This utility model provides, for example Figure 1-5 As shown: Example
[0037] A rocking chair motor swing angle mechanical limiting device includes:
[0038] The rocking chair body 1 has a second fixing frame 7 fixedly installed at its bottom.
[0039] The base 2 is located below the rocking chair body 1. A first fixing frame 3 is fixedly installed on the side of the base 2 near the rocking chair body 1. The base 2 is used to support the rocking chair body 1.
[0040] The transmission mechanism is located between the rocking chair body 1 and the base 2. The transmission mechanism includes a moving part and a driving part. The moving part is used to connect the rocking chair body 1 and the base 2, and the driving part is located on the surface of the base 2 and is used to drive the moving part.
[0041] It should be noted that the base 2 is located on the bottom surface of the rocking chair body 1, and the transmission mechanism is located between the rocking chair body 1 and the base 2. The moving part connects the base 2 and the rocking chair body 1, and the moving part is driven by the drive part to move, and the moving part pushes the rocking chair body 1, causing the rocking chair body 1 to shake.
[0042] The mobile unit includes:

[0044] The swing rod 6 has one end hinged to the end of the hinge rod 4 away from the first fixed frame 3, and the end of the swing rod 6 away from the hinge rod 4 is hinged to the second fixed frame 7.
[0045] The pusher is located inside the hinge rod 4 and is used to drive the transmission of the drive unit.
[0046] It should be noted that the swing rod 6 is located above the hinge rod 4, and the swing rod 6 is rotatably connected to the hinge rod 4. The hinge rod 4 is pushed by the pushing part, causing the hinge rod 4 to move. The movement of the hinge rod 4 drives the swing rod 6 to move. The swing rod 6 is rotatably connected to the second fixed frame 7, which is located on the bottom surface of the rocking chair body 1, thereby causing the rocking chair body 1 to shake.
[0047] The surface of the rocking chair body 1 is fixedly fitted with sponge, and armrests 15 are fixedly fitted on both sides of the rocking chair body 1.
[0048] It should be noted that the surface of the rocking chair body 1 is covered with sponge.

Both sides of the rocking chair body 1 are equipped with armrests 15, which can support the user when the rocking chair body 1 is rocking, so as to prevent the user from falling.
[0049] An anti-slip pad 16 is fixedly installed on the bottom surface of the base 2, and the bottom surface of the anti-slip pad 16 is provided with anti-slip texture;
[0050] It should be noted that the bottom surface of the base 2 is equipped with an anti-slip pad 16. The anti-slip pad 16 is used to increase the friction between the base 2 and the ground, so as to prevent the base 2 from becoming unstable when the rocking chair body 1 shakes, which would cause the rocking chair body 1 to tip over.
[0051] Example 2: This utility model provides a pushing part, applied to a rocking chair motor swing angle mechanical limiting device in Example 1. The pushing part includes:
[0052] Fixed rod 5 is fixedly installed inside the push groove;
[0053] Push rod 8, one end of push rod 8 is hinged to fixed rod 5;
[0054] The transmission rod 9 has one end hinged to the end of the push rod 8 away from the fixed rod 5, and the end of the transmission rod 9 away from the push rod 8 is fixedly connected to the drive unit. The transmission rod 9 is used for transmission of the drive unit.
[0055] It should be noted that the fixed rod 5 is fixedly installed in the push groove, the push rod 8 is located inside the base 2, one end of the push rod 8 is rotatably connected to the fixed rod 5, the end of the push rod 8 away from the fixed rod 5 is rotatably connected to the transmission rod 9, and the end of the transmission rod 9 away from the push rod 8 is fixedly connected to the drive unit. The drive unit drives the transmission rod 9 to move, the transmission rod 9 drives the push rod 8 to move, the push rod 8 pushes and pulls the fixed rod 5, drives the hinge rod 4 to move, and thus drives the rocking chair body 1 to shake.
[0056] Specifically, the drive unit includes:
[0057] Fixing plate 11 is fixedly installed on the surface of base 2;
[0058] Drive motor 10 is fixedly mounted on the surface of fixed plate 11;
[0059] Rotating rod 14, one end of rotating rod 14 is fixedly connected to the output shaft of drive motor 10, and the end of rotating rod 14 away from drive motor 10 is fixedly connected to transmission rod 9;
[0060] A limiting mechanism is provided on the surface of the fixed plate 11 and is used to limit the swing angle of the motor.
[0061] It should be noted that the fixing plate 11 is fixedly installed on the surface of the base 2, and the drive motor 10 is fixedly installed on the side of the fixing plate 11 away from the base 2. The output shaft of the drive motor 10 is fixedly connected to one end of the rotating rod 14, and the end of the rotating rod 14 away from the drive motor 10 is fixedly connected to the transmission rod 9. When the drive motor 10 is started, the output shaft of the drive motor 10 drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the transmission rod 9 to swing, which in turn drives the rocking chair body 1 to shake through the transmission belt. The rotation angle of the rotating rod 14 is limited by the limiting mechanism to prevent the rotation angle from being too large.
[0062] Furthermore, the limiting mechanism includes:
[0063] Limiting plate 12 is fixedly installed on the surface of fixing plate 11, and a limiting groove is formed on the surface of limiting plate 12;
[0064] Limiting member 13 is fixedly sleeved on the end of rotating rod 14 away from drive motor 10, and limiting member 13 is slidably connected to limiting groove;
[0065] It should be noted that the limiting plate 12 is located at the front end of the output shaft of the drive motor 10. A limiting groove is formed on the limiting plate 12, and the limiting member 13 is slidably connected in the limiting groove. The limiting member 13 is fixedly sleeved with the end of the rotating rod 14 away from the drive motor 10. When the drive motor 10 is started, the output shaft of the drive motor 10 drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the limiting member 13 to rotate, so that the limiting member 13 rotates in the limiting groove. Due to the space limitation of the limiting groove, the rotation amplitude of the limiting member 13 is controlled, thereby limiting the swing angle of the motor. This can effectively control the rocking chair's swaying amplitude and prevent the rocking chair from swaying too much and causing a fall when the user is not fully in contact with the rocking chair, thus improving safety.
