[0034] 4. Steering seat; Detailed Implementation

[0035] The present invention will be further described below with reference to specific embodiments:

[0036] An anti-rotation table is used in a vehicle, which includes a frame 1, a fixed seat 2, a table 3, and a steering seat 4. The frame 1 has a chassis 11, the fixed seat 2 is mounted on the chassis 11 for a user to sit on, the table 3 is mounted on the chassis 11 and located on one side of the fixed seat 2, and the steering seat 4 is located on one side of the table 3. The steering seat 4 has a reversing component for adjusting the orientation of the steering seat 4 so that the steering seat 4 faces the table 3.

[0037] like Figure 1 As shown, the vehicle in this patent is a sightseeing vehicle. The frame 1 is equipped with a front suspension assembly 13, with an instrument panel and steering wheel mounted above the front suspension assembly 13, and a front wheel 131 mounted below the front suspension assembly 13. A rear suspension assembly 14 is located at the rear of the frame 1, with a rear wheel 141 mounted below the rear suspension assembly 14. The chassis 11 is located between the front suspension assembly 13 and the rear suspension assembly 14, and the fixed seat 2, table 3, and steering seat 4 are mounted on the chassis 11.

[0038] The table 3 in this patent is used for placing items, and specifically includes a base 31, a tabletop 32, and a table rod 33. The base 31 is directly fixed to the chassis 11. The tabletop 32 has a storage slot and several cup slots or ashtrays for placing items such as water cups and ashtrays. One end of the table rod 33 is connected to the tabletop 32, and the other end is rotatably connected to the base 31. An anti-rotation component is provided between the table rod 33 and the base 31, which includes an anti-rotation protrusion 35 and an anti-rotation recess 34 disposed on the end face of the table rod 33 between it and the base. The anti-rotation protrusion 35 is positioned within the anti-rotation recess 34 to restrict the rotation of the table rod 33.

[0039] refer to Figure 2 , 3 The base 31 is circular, with several fixing holes along its outer edge. Screws are installed in these holes, allowing it to be directly fixed to the chassis 11. It should be noted that the base 31 is directly fixed to the chassis 11 during vehicle manufacturing and will not be disassembled during actual vehicle use. The base 31 has a disc-shaped structure and a low height, so removing the table arm 33 will not significantly affect the user's activities within the vehicle. The table arm 33 is cylindrical and fixed to the center of the base 31. It includes a hollow rod portion 331, with a flange 331 fitted onto the top of the rod portion 331, which is fixedly connected to the bottom of the tabletop 32. A connector 39 is located at the bottom of the rod portion 331, inserting into one end of the hollow rod portion 331 and connecting to the base 31.

[0040] like Figure 4-6 As shown, a screw 36 and a threaded hole 37 are provided between the table rod 33 and the base 31 for rotational locking. Specifically, a screw 36 is fixed to the center of the connector 39 by welding or glue, and a threaded hole 37 is provided in the center of the base 31. During installation, the table rod 33 is fixed to the base 31 by rotating it after aligning the screw 36 with the threaded hole 37. Since the screw 36 is fixed to the connector 39, when the table rod 33 is disassembled, there will be no protruding screw 36 on the base 31, thus not affecting the user's movement in the vehicle.

[0041] The anti-rotation recess 34 is integrally formed on the end face of the connector 39. In this embodiment, the anti-rotation recess 34 includes a plurality of anti-rotation grooves 343 or anti-rotation holes disposed on the end face of the table rod 33. In this embodiment, it is an anti-rotation groove 343. The anti-rotation groove 343 is disposed around the outer edge of the screw 36. A plurality of anti-rotation grooves 343 are arranged sequentially, and a first anti-rotation protrusion 34A is formed between adjacent anti-rotation grooves 343. The anti-rotation protrusion 35 is disposed in the base 31, such as Figure 5As shown, the base 31 has a mounting cavity 311, and two operating holes 313 connected to the mounting cavity 311 are provided on the base 31. The anti-rotation protrusion 35 is connected to a reset member, preferably a spring, to give the anti-rotation protrusion 35 a tendency to move towards the anti-rotation recess 34. One end of the anti-rotation protrusion 35 is connected to an operating part 351, which controls the anti-rotation protrusion 35 to move against the reset force of the reset member. In fact, the mounting cavity 311 has a support strip 352 connecting the anti-rotation protrusion 35 and the operating part 351. The support strip 352 is strip-shaped, and both ends of the support strip 352 are opposite to the operating holes 313, so that the anti-rotation protrusion 35 and the operating part 351 on both ends of the support strip 352 are exposed outside the base 31 through the corresponding operating holes 313.

[0042] like Figure 6 As shown, several anti-rotation protrusions 35 are arranged in a fan shape, engaging with the first anti-rotation protrusion 34A in the connector 39 within the base 31. Simultaneously, a reset member is provided within the mounting cavity 311, abutting against the support bar 352 to ensure tight engagement between the anti-rotation protrusions 35 and the anti-rotation grooves 343. Since the first anti-rotation protrusion 34A abuts against the side of the anti-rotation protrusion 35, the anti-rotation protrusion 35 is positioned within the anti-rotation groove 34, preventing the table rod 33, rotatably connected to the base 31, from moving in the direction of loosening. This prevents the connection between the table rod 33 and the base 31 from loosening, ensuring stable installation of the fixed table 3. Only one anti-rotation groove 34 may be provided; providing multiple anti-rotation grooves 34 increases the anti-rotation effect.

[0043] Furthermore, the first anti-rotation protrusion 34A has a guide surface 341 and a stop surface 342 on both sides. The guide surface 341 is used to allow the anti-rotation protrusion 35 to slide along the guide surface 341 when the table rod 33 is rotated and locked onto the base 31; the stop surface 342 is used to allow the anti-rotation protrusion 35 to abut against the stop surface 342 to restrict the rotation of the table rod 33 when the table rod 33 is rotated and unlocked from the base 31. Figure 6As shown, the first anti-rotation protrusion 34A has a right-angled triangle cross-section, making the guide surface 341 an inclined plane and the stop surface 342 a vertical plane. When the table rod 33 rotates clockwise, the anti-rotation protrusion 35 slides along the inclined guide surface 341 and moves into the mounting cavity 311 against the reset force of the reset member. At this time, the table rod 33 can be selected to fix it more tightly to the base 31. When the table rod 33 rotates counterclockwise, the anti-rotation protrusion 35 abuts against the vertical stop surface 342. Since there is no inclined plane to guide the movement of the anti-rotation protrusion 35, the counterclockwise movement of the table rod 33 can be restricted by the anti-rotation protrusion 35, thereby preventing the rotational connection between the table rod 33 and the base 31 from loosening. If the user needs to disassemble the table rod 33, he / she only needs to press the operating part 351 so that the anti-rotation protrusion 35 is no longer abutting against the vertical stop surface 342, and the user can then rotate the table rod 33 counterclockwise to disassemble it. In summary, this patent achieves the anti-rotation and anti-loosening of the table rod 33 without affecting its normal rotation and fixation by using the guide surface 341 and the stop surface 342, thus reducing the difficulty of its use.

[0044] Furthermore, a washer 38 is provided between the table rod 33 and the base 31. In this embodiment, the washer 38 is fitted outside the screw 36 by screws and is located in the surrounding anti-rotation groove 343. The washer 38 is used to install between the table rod 33 and the base 31, making the connection between the two more stable, ensuring the installation stability of the fixed tabletop, and preventing the vibration generated during the use of the fixed table 3 from causing friction between the precision contact anti-rotation groove 34 and anti-rotation protrusion 35, thus effectively increasing their service life.
