DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0028] Embodiment 1: In order to solve the problem that the prior art is only applicable to some small-sized automobile chassis, the following technical solution is disclosed. Figure 1-Figure 2 As shown, the support mechanism is arranged on the support frame 1 and is moved up and down by a transmission mechanism; the support mechanism includes a support plate 2 slidably connected to the support frame 1 and a limit rod 13 fixed on the connecting plate 7, and the lower end of the limit rod 13 is located below the support plate 2.

[0029] A hydraulic cylinder 12 is installed on the right side of the support frame 1 , and the output end of the hydraulic cylinder 12 is fixed to the right side mounting plate 4 . A fixing rod 3 is installed on the lower end of the mounting plate 4 , and the fixing rod 3 passes through the support plate 2 .

[0030] A spring is arranged between the left connecting plate 7 and the mounting plate 4, and magnets 5 are installed at the lower end of the mounting plate 4 and the upper end of the supporting plate 2, and the upper and lower magnets 5 attract each other.

[0031] The transmission mechanism includes a mounting gear row 8 fixed on the left connecting plate 7, a transmission gear 9 rotated on the support frame 1 through an axle rod, and a fixed gear row 10 fixed on the support plate 2, and both the fixed gear row 10 and the mounting gear row 8 are meshed with the transmission gear 9.

[0032] The automobile chassis is placed on the supporting plate 2, and then the hydraulic cylinder 12 makes the right mounting plate 4 move to the left. When the right mounting plate 4 moves to contact with the right side of the automobile chassis, the right mounting plate 4 pushes the automobile chassis, thereby making the automobile chassis move to the left. When the automobile chassis moves to the left and contacts with the fixing plate 6, the automobile chassis makes the left fixing plate 6 move to the left. During the movement of the fixing plate 6 to the left, the limiting rod 13 and the mounting gear row 8 move downward synchronously. The limiting rod 13 moves to the left and separates from the supporting plate 2. After that, when the mounting gear row 8 moves to engage with the transmission gear 9, the mounting gear row 8 makes the transmission gear 9 rotate counterclockwise. The rotation of the transmission gear 9 makes the fixed gear row 10 and the supporting plate 2 move downward synchronously. The downward movement of the supporting plate 2 will not affect the normal flipping of the automobile chassis in the later stage.

[0033] Embodiment 2: This embodiment can make the automobile chassis turn over stably, see Figure 2-Figure 7 As shown, a vehicle chassis turning mechanism includes a fixing plate 6, which is rotatably connected to a connecting plate 7 through a shaft;

[0034] The limiting plate 16 is sleeved on the shaft rod of the right fixing plate 6; the limiting mechanism is arranged on the right side of the support frame 1, and the automobile chassis is limited by moving the limiting plate 16, and the limiting plate 16 is fixed to the left side of the fixing plate 6; a servo motor 11 is installed on the right side of the support frame 1, and a fan gear 14 is fixed to the output end of the servo motor 11, a reciprocating screw rod 17 is rotatably connected to the mounting plate 4 on the right side, and a full gear 15 is installed on the right end of the reciprocating screw rod 17 and the shaft rod of the right fixing plate 6, and a ratchet assembly is installed inside the full gear 15, the fan gear 14 and the full gear 15 are meshed with each other, the left end of the reciprocating screw rod 17 is threadedly connected to a mounting column 18, and the mounting column 18 slides on the right side of the limiting plate 16, and a plug rod is installed on the left end of the limiting plate 16, and the plug rod can be inserted into the automobile chassis through the fixing plate 6;

[0035] Before flipping, the servo motor 11 runs to make the fan gear 14 rotate synchronously, and the fan gear 14 rotates counterclockwise. When the fan gear 14 rotates to engage with the full gear 15, the full gear 15 rotates clockwise. The upper full gear 15 will not rotate due to the setting of the ratchet assembly fixed plate 6. The lower full gear 15 rotates to drive the reciprocating screw rod 17 to rotate synchronously. The reciprocating screw rod 17 rotates to make the mounting column 18 move to the left side. The mounting column 18 moves to the left side and drives the limit plate 16 to move to the left side synchronously. The limit plate 16 moves to the left side and drives the insertion rod to move to the left side synchronously. The insertion rod is inserted into the automobile chassis through the fixed plate 6 to limit the automobile chassis to prevent the automobile chassis from being unstable during the flipping process. Then the servo motor 11 runs in the opposite direction. According to the above principle, the upper full gear 15 rotates to rotate the fixed plate 6, and the reciprocating screw rod 17 below will not rotate. The fixed plate 6 rotates to drive the automobile chassis to rotate synchronously, thereby realizing the flipping of the automobile chassis.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
