Abstract
Description
Technical Field

[0002] Verifying a model car means building a simplified, small-scale vehicle model and conducting various tests and trials to evaluate the feasibility and performance of the vehicle design. This method can effectively reduce development costs and time, and detect potential problems and defects before actual production. Among them, the seats in the model car are verified to ensure that the design, manufacture and installation of the seat rotation mechanism meet the relevant requirements and standards. The main purpose of this verification is to ensure the safety, reliability and applicability of the seat rotation mechanism.
[0003] The existing method of verifying the seat of a model car is usually to fix the seat on the seat mounting panel, and the seat is tested in all directions by rotating the mounting panel. The rotation of the seat mounting panel is usually driven by a motor to drive the driving gear in the transmission mechanism, and the driving gear drives the driven gear to rotate, so that the seat mounting panel connected to the driven gear rotates. However, in this rotation method, the driving gear and the driven gear are meshed transmission. After long-term use, the teeth on the gears are worn due to repeated meshing, resulting in gaps between the teeth when meshing, which easily causes the installed seat to shake when rotating, thereby affecting the verification results.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-Figure 2 , Figure 4 As shown, the utility model provides an embodiment of a seat rotation mechanism for verifying a model car, comprising: a fixed base 1 and a seat support plate 3, the seat support plate 3 is provided with a rotating shaft 31, the rotating shaft 31 is fixed to the bottom of the seat support plate 3, the rotating shaft 31 is fixedly installed with a rotating bearing 4, the outer wall of the rotating bearing 4 is fixedly installed on the fixed base 1, and the fixed base 1 is rotatably connected to the seat support plate 3.
[0025] like Figure 1-Figure 2 As shown, the fixed base 1 is connected to the driving assembly 2, and the driving assembly 2 includes a bracket 21, and the bracket 21 is fixedly installed on the fixed base 1. The bracket 21 is fixedly installed with a motor 22, and the motor 22 is used to drive the rotating shaft 31 to rotate.
[0026] Specifically, Figure 2 , Figure 4-Figure 5 As shown, a transmission shaft 23 is provided at the output end of the motor 22, a slot 32 is provided on the rotating shaft 31, the transmission shaft 23 is provided in the slot 32, a key slot is provided on one side of the slot 32 facing outward, and a key slot is provided on one side of the transmission shaft 23 facing inward, a flat key pin 24 is stuck between the two key slots, and the transmission shaft 23 is connected to the rotating shaft 31 through the flat key pin 24. The flat key pin 24 serves as a fixing part for fixing the relative position of the transmission shaft 23 and the rotating shaft 31, so that the transmission shaft 23 can drive the rotating shaft 31 to rotate when it rotates.
[0027] like Figure 1-Figure 4As shown, the fixed base 1 is connected to the stop assembly 5, and the stop assembly 5 includes a first limit block 51 and a second limit block 52, which are both fixedly installed on the fixed base 1, and the first limit block 51 and the second limit block 52 are symmetrically arranged relative to the rotating bearing 4, and the seat support plate 3 is fixed with a limit block 53 by bolts, and the limit block 53 can contact the first limit block 51 or the second limit block 52 when rotating, and the fixed base 1 is also fixedly installed with a first photoelectric limit sensor 54 and a second photoelectric limit sensor 55, and the first photoelectric limit sensor 54 and the second photoelectric limit sensor 55 are both electrically connected to the motor 22, so that the motor 22 can be started and stopped according to the sensing conditions of the photoelectric limit sensor, and the seat support plate 3 is fixedly installed with a first baffle 56 and a second baffle 57, wherein the first photoelectric limit sensor 54 and the first baffle 56 are symmetrically arranged relative to the rotating bearing 4, and the second photoelectric limit sensor 55 and the second baffle 57 are symmetrically arranged relative to the rotating bearing 4.
[0028] In this embodiment, the seat of the model car is first fixed on the seat support plate 3, and the motor 22 is turned on. The motor 22 drives the transmission shaft 23 to rotate, and the transmission shaft 23 drives the rotating shaft 31 to rotate through the flat key pin 24, so that the seat support plate 3 and the seat rotate. When the seat needs to rotate 180° clockwise, the motor 22 drives the seat support plate 3 to rotate clockwise. When it rotates clockwise to 180°, the limit block 53 contacts the second limit block 52, and the second baffle 57 contacts the second photoelectric limit sensor 55, and the motor 22 stops working; when the seat needs to rotate 180° counterclockwise, the bolts connecting the limit block 53 and the seat support plate 3 are removed, and the limit block 53 is rotated 180° and then fixed in place by bolts.

[0029] It is understandable that when the motor 22 stops driving, the seat support plate 3 stops rotating. The rotation of the seat support plate 3 is adjusted by the motor 22, so that the seat installed on the seat support plate 3 can rotate more stably and is less likely to shake, thereby improving the accuracy of the seat verification result.
[0030] In addition, the gears in the prior art have high requirements on meshing accuracy during processing, which increases processing costs and makes assembly between gears more difficult. Compared with the prior art, the present application greatly reduces processing costs and assembly difficulty.
[0031] Working principle: fix the seat of the model car on the seat support plate 3, turn on the motor 22, the motor 22 drives the transmission shaft 23 to rotate, and the transmission shaft 23 drives the rotating shaft 31 to rotate through the flat key pin 24, so that the seat support plate 3 and the seat rotate. When the seat needs to rotate 180° clockwise, the motor 22 drives the seat support plate 3 to rotate clockwise. When it rotates clockwise to 180°, the limit block 53 contacts the second limit block 52, and the second baffle 57 contacts the second photoelectric limit sensor 55, and the motor 22 stops working; when the seat needs to rotate 180° counterclockwise, remove the bolts connecting the limit block 53 and the seat support plate 3, rotate the limit block 53 180° and then fix it in place with bolts, the motor 22 drives the seat support plate 3 to rotate counterclockwise. When it rotates counterclockwise to 180°, the limit block 53 contacts the first limit block 51, and the first baffle 56 contacts the first photoelectric limit sensor 54, and the motor 22 stops working.
[0032] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
