Description

Technical Field

[0001] The invention relates to the field of single-person functional chairs, in particular to a single-person functional chair with forward and backward reciprocating linear motion. Background Art

[0002] With the continuous development of seats, users have higher and higher requirements for the functions of seats. They not only need to meet the requirements of sitting comfort but also be able to adjust and move to conform to human mechanics. Therefore, adjustable seats came into being.

[0003] However, the existing adjustable seats often require manual operation, and the adjustment process is not labor-saving enough. Therefore, there is a need for an electric seat that can do reciprocating linear motion forward and backward to be suitable for vehicles such as cars, cabins, and ships, so as to adjust the front and rear distance of the seat and make people sit comfortably.

[0004] At the same time, there is a lack of electric seats that can move back and forth in simulation tests. For example, in the detection of seat belts, the existing seat belt detection often only places the seat belts on a stretching table for stretching tests to judge the quality of the seat belts, but lacks simulation tests of actual collision scenarios. Therefore, it is necessary to fasten the seat belts to the electric seat and tie the dummy to it, and then accelerate the electric seat to make a linear motion to simulate the collision scene, and then test the reliability of the seat belts.

[0005] The existing electric seats cannot move back and forth according to the rhythm, so as to achieve the user's perception of harmonious, structural and flowing music. The functional chair of the present invention has rhythmic and repetitive mechanical movement, and the operation is smoother, achieving visual enhancement and dynamic attraction. The cheerful rhythm and musical shaking bring comfort and entertainment to the passengers. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 14 , the present invention provides a technical solution: like Figure 1-Figure 14 As shown, a single-person functional chair with forward and backward reciprocating linear motion comprises a seat 1, a placement plate 2, and a base 4. The base 4 is provided with an adjustment mechanism and a driving trolley 3. The adjustment mechanism drives the driving trolley 3 to perform rhythmic reciprocating linear motion. The seat 1 cooperates with the placement plate 2, and the placement plate 2 is connected and fixed to the driving trolley 3. The seat 1 realizes rhythmic forward and backward reciprocating linear motion through the driving trolley 3 and the adjustment mechanism. The rhythmic forward and backward reciprocating linear motion is a forward and backward reciprocating linear motion according to a specific rhythm and change pattern. The adjustment mechanism includes an upper frame 401, a lower frame 402, a side frame 403, an active synchronous pulley assembly 404, and a driven synchronous pulley assembly 405; a control system 408 is provided in the upper frame 401, and a U-shaped photoelectric switch 4071 is provided on the upper beam 407; the active synchronous pulley assembly 404 includes a motor, a reducer, and an active synchronous pulley; The control system 408 also includes a rhythmic rotation program, which controls the motor speed or direction to change under a set regularity, creating a specific rhythm through regular changes to form a rhythmic motion effect; The rhythmic rotation program is specifically to write a two-dimensional coordinate point in a two-dimensional plane coordinate system composed of an x-axis and a y-axis. The value on the x-axis corresponding to the coordinate point represents the actual time corresponding to the driving car 3 when performing a rhythmic reciprocating linear motion. The value on the y-axis corresponding to the coordinate point represents the actual frequency of the pulse emitted by the control system 408 at the actual time corresponding to the rhythmic reciprocating linear motion. The multiple coordinate points (x, y) rise and fall continuously in sequence to form a smooth and smooth two-dimensional curve. The control system 408 generates smooth, continuous and rhythmic pulses to control the motor to rotate under the pulse drive. When the reciprocating linear motion is forward, it is forward, and vice versa. The reciprocating linear motion is fed back to the control system 408 through the U-shaped photoelectric switch 4071 to control the corresponding forward and reverse rotation of the motor. The control system 408 can be remotely controlled through an external control device, thereby controlling the seat 1 to stop and start the rhythmic forward and backward reciprocating linear motion.

[0023] Through the above technical solution: the rhythmic rotation program calls the driver program through the signal received by the U-shaped photoelectric switch 4071, and the control system thereby sends out a pulse of actual frequency, and uses the specific value of the actual frequency of the pulse as the value of the y-axis of the two-dimensional coordinate point, and uses the time of sending the pulse of actual frequency, that is, the actual time when the control system controls the driving car 3 to perform rhythmic reciprocating linear motion as the x-axis value of the coordinate point. As the actual time of the reciprocating linear motion goes by, multiple coordinate points (x, y) are connected in sequence to form a continuous and smooth undulating curve.

[0024] The driving trolley 3 follows the two-dimensional curve to make rhythmic reciprocating linear motion. The seat 1 is placed on the placement plate 2, and the placement plate 2 is connected to the driving trolley 3 in the base 4, so that when the driving trolley 3 makes rhythmic reciprocating linear motion through the adjustment mechanism, it drives the seat 1 above to move together, thereby realizing the rhythmic forward and backward adjustment function of the seat 1. The control system is turned on or off by the button of the external control device. When the control system is turned off, it no longer sends out pulses of the actual frequency, and the driving trolley 3 stops moving, thereby driving the seat 1 to stop moving. The entire structure is simple and easy to operate.
