DETAILED DESCRIPTION
[0021] In order to better understand the present invention, the technical scheme of the present invention will be clearly and completely described below through embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] like Figures 1 to 5 As shown, a car driving simulation steering wheel return positioning device includes a transmission shaft 1, a limiting body 2 and a shell 3. The end of the transmission shaft 1 is connected to the steering wheel 4, the transmission shaft 1 rotates with the steering wheel 4, the transmission shaft 1 passes through the limiting body 2, the transmission shaft 1 is connected to the limiting body 2 through a clamping plate 5, the limiting body 2 rotates with the transmission shaft 1, a spiral groove 6 is arranged on the limiting body 2, a limiting pin 7 fixed to the shell 3 is inserted into the spiral groove 6, the number of thread turns of the spiral groove 6 is 1.5 turns, and after the limiting body 2 rotates 540° (1.5*360°) with the steering wheel 4, the limiting pin 7 cooperates with the spiral groove 6 to achieve the positioning of the rotation angle of the steering wheel 4.
[0023] The end of the position-limiting body 2 is provided with a slot 8, which is spiral-shaped, and the number of spiral turns of the spiral slot 8 is 1.5 turns. The card plate 5 is clamped at the end of the slot 8, and the position-limiting body 2 is driven to rotate along with the transmission shaft 1 through the card plate 5. The slots 8 are respectively arranged at both ends of the position-limiting body 2, and the slots 8 are divided into an upper slot 81 and a lower slot 82. The upper slot 81 is in a counterclockwise spiral direction, and the lower slot 82 is in a clockwise spiral direction. The card plate 5 is clamped at the ends of the upper slot 81 and the lower slot 82. The card plate 5 is divided into an upper card plate 51 and a lower card plate 52. The upper card plate 51 and the lower card plate 52 are clamped at the ends of the upper slot 81 and the lower slot 82, respectively. The card plate 5 is elastic, and when the position-limiting body 2 rotates, the card plate 5 moves along the slot 8.
[0024] The limiter 2 is divided into an upper limiter 21 and a lower limiter 22. The upper limiter 21 is connected to the transmission shaft 1 through an upper clamping plate 51, and the lower limiter 22 is connected to the transmission shaft 1 through a lower clamping plate 52. The upper limiter 21 and the lower limiter 22 are respectively provided with spiral grooves 6 with opposite spirals. The limiter pins 7 fixed to the housing 1 are respectively inserted into the spiral grooves 6. The positioning of the steering wheel 4 is achieved through the action of the limiter pins 7 and the spiral grooves 6. A spring 9 is connected between the upper limiter 21 and the lower limiter 22. One end of the spring 9 is connected to the upper limiter 21, and the other end of the spring 9 is connected to the lower limiter 22. The upper limiter 21 and the lower limiter 22 are automatically returned by the spring 9. The spring 9 is stretched as the steering wheel 4 rotates. When the steering wheel 4 rotates a certain angle, the steering wheel 4 is released, and the stretched spring 9 releases the elastic potential energy, and the upper limiter 21 or the lower limiter 22 is automatically reset. The upper limit body 21 is inserted into the lower limit body 22, and the upper limit body 21 is rotatably connected to the lower limit body 22. The outer walls of the upper limit body 21 and the lower limit body 22 are provided with a shell 3, the upper limit body 21 and the lower limit body 22 are located in the shell 3, the limit pin 7 is fixedly connected to the shell 3, and the shell 3 is connected to the limit body 2 through the limit pin 7.
[0025] Working principle: when the steering wheel 4 is rotated clockwise, the transmission shaft 1 rotates clockwise with the steering wheel 4, and the upper clamping plate 51 connected to the transmission shaft 1 is clamped at the end of the upper clamping groove 81. The upper clamping groove 81 is counterclockwise in thread direction. The upper clamping plate 51 drives the upper limit block 21 to rotate clockwise. The upper limit block 21 is acted upon by the limiting pin 7. The upper limit block 21 moves upward relative to the transmission shaft 1. The number of thread turns of the spiral groove 6 is 1.5 turns. When the limiting pin 7 moves relatively to the tail end of the spiral groove 6, the limiting pin 7 is clamped on the spiral groove 6, and the steering wheel 4 rotates clockwise to the maximum limit. The steering wheel 4 rotates clockwise to 540 degrees, thereby realizing the positioning of the steering wheel 4. In this process, the lower clamping plate 52 connected to the transmission shaft 1 is clamped at the end of the lower clamping groove 82, and the lower clamping groove 82 is in a clockwise thread direction. The lower clamping plate 52 moves along the lower clamping groove 82. Since the lower clamping plate 52 does not squeeze the lower clamping groove 82 to act on the lower limit body 22, the lower clamping plate 52 cannot drive the lower limit body 22 to move, and the lower limit body 22 remains stationary. Therefore, as the upper limit block 21 moves upward along the transmission shaft 1, the spring 9 connected between the upper limit block 21 and the lower limit body 22 is continuously stretched, and when the steering wheel 4 is released, the spring 9 releases the elastic potential energy, and the upper limit block 21 automatically returns to its position.
[0026] On the contrary, when the steering wheel 4 is turned counterclockwise, the transmission shaft 1 rotates counterclockwise with the steering wheel 4, and the transmission shaft 1 drives the lower limit body 22 to rotate counterclockwise. The lower limit body 22 moves downward relative to the transmission shaft 1 under the action of the limit pin 7, and the upper limit body 21 is not squeezed by the upper clamping plate 51, so the upper limit body 21 always remains stationary until the limit pin 7 moves relatively to the end of the spiral groove 6, and the steering wheel 4 rotates counterclockwise to the maximum limit. At this time, the steering wheel 4 rotates counterclockwise by 540 degrees. Similarly, in this process, as the lower limit body 22 moves downward along the transmission shaft 1, the spring 9 connected between the upper limit block 21 and the lower limit body 22 is continuously stretched, and when the steering wheel 4 is released, the spring 9 releases the elastic potential energy, and the lower limit block 22 automatically resets.
[0027] 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 principle of the present invention should be included in the protection scope of the present invention.
