[0043] Further, the transmission mechanism comprises a clamping arm 5, the clamping arm 5 is in a bent shape, the clamping arm 5 is rotationally connected with the top end of the base 1 through a rotating shaft 3, the rotating shaft 3 is provided with a first torsion spring 4, one end of the clamping arm 5 is fixedly connected with a pushing block 6, the pushing block 6 corresponds to the receiving end of the executing mechanism, the other end of the clamping arm 5 is fixedly connected with a ratchet wheel 7, one end of the ratchet wheel 7 away from the clamping arm 5 is fixedly connected with a pin 2 on the side wall, and the ratchet wheel 7 is matched with the triggering mechanism.

[0044] Further, the triggering mechanism comprises a push-pull electromagnet 8, the push-pull electromagnet 8 is fixedly connected with the bottom of the base 1, one end of a sliding rod 11 fixedly connected with the push-pull electromagnet 8, the other end of the sliding rod 11 is fixedly connected with a boss 12 on the top, the boss 12 abuts against a triggering part rotationally connected on the base 1, the triggering part is matched with the ratchet wheel 7, and the sliding rod 11 is slidingly matched with the base 1 through a limiting rod 10 arranged on the base 1.

[0045] Further, the triggering part comprises a ratchet switch 13, the ratchet switch 13 is rotationally connected with the base 1, the ratchet switch 13 abuts against the boss 12, one side of the ratchet switch 13 is fixedly connected with a second torsion spring 14, the other end of the ratchet switch 13 is fixedly connected with a ratchet 15, the ratchet 15 is matched with the ratchet wheel 7, and the pin 2 is in contact with the ratchet switch 13.

[0046] When the automobile is normally driven, the clamping arm 5 has a tendency to rotate clockwise under the action of the first torsion spring 4, but the pin 2 on the clamping arm 5 is blocked by the ratchet switch 13, the lower end of the ratchet switch 13 is blocked by the boss 12 of the sliding rod 11, and the clamping arm 5 cannot rotate clockwise.

[0047] When the automobile is punctured, the push-pull electromagnet 8 obtains an electric signal and pushes the sliding rod 11 forward, the lower end of the ratchet switch 13 loses the support of the boss 12 and rotates counterclockwise under the joint action of the second torsion spring 14 and the pin 2 on the clamping arm 5, so that the clamping arm 5 can also rotate clockwise, and finally the clamping arm 5 moves to a posture parallel to the base 1.

[0048] During the clockwise rotation of the clamping arm 5, even if the upper end hook of the pawl 15 contacts the ratchet wheel 7 part of the clamping arm 5, it will not prevent the clockwise movement of the clamping arm 5, but the upper end hook of the pawl 15 is in close contact with the ratchet wheel 7 part of the clamping arm 5 under the action of the second torsion spring 14, preventing the clamping arm 5 from reversing. When used again, the push-pull electromagnet 8 pulls the sliding rod 11 back, the boss 12 on the sliding rod 11 lifts the pawl switch 13, the pawl 15 leaves the ratchet wheel 7, and the clamping arm 5 is manually pulled up. When the pin 2 lifts the pawl switch 13, the clamping arm 5 can be lowered.

[0049] When the car has a flat tire, the clamping arm 5 moves to a horizontal position, and the rear end of the clamping arm 5 is slightly higher than the front end of the starting swing arm 21. The starting swing arm 21 rotates with the wheel and extends into the brake side through the gap between the spokes. When the clamping arm 5 is lifted, the front end of the starting swing arm 21 only rotates with the wheel and does not interfere with the rear end of the clamping arm 5. When the clamping arm 5 is lowered to a horizontal position, the front end of the starting swing arm 21 will encounter the rear end of the clamping arm 5 fixed with the brake, and be lifted by the block 6 on the rear end of the clamping arm 5.

[0050] The starting swing arm 21 rotates and drives the rotation switch 24 to rotate. With the rotation of the rotation switch 24, the rotation switch 24 releases the restriction on the locking table 25, and the guide block 9 moves upward under the action of the starting spring 20. At the same time, the rotation amplitude of the rotation switch 24 makes the limiting swing arm 33 rotate beyond the balance position and rotate to the other extreme position, but this rotation action is temporarily stopped due to the interference between the rotation switch 24 and the locking table 25.

[0051] When the guide block 9 moves upward to the limit position, the rotation switch 24 no longer interferes with the locking table 25, and the rotation switch 24 locks the other end of the locking table 25 through the limiting swing arm 33 under the action of the limiting spring 34, and at the same time, the limiting swing arm 33 reaches the other extreme position. At this time, the two replacement wheels 29 move to the same circular surface.

[0052] Because the distance between the guide block 9 and the hinge of the two replacement wheels 29 is smaller than the distance between the rotating shaft 28 on the shell 16, as the guide block 9 moves upward, the two replacement wheels 29 will fan each other, the blocking strip 30 and the blocking block 31 form interlocking, and at the same time, the blocking strip 30 supports the blocking block 31 in the radial direction, finally stops the fanning motion, and together forms a fan surface.

[0053] In the description of the present application, it needs to be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0054] The above-described embodiments are only to describe the preferred modes of the present application, and not to limit the scope of the present application, and various modifications and improvements to the technical solutions of the present application made by those skilled in the art without departing from the design spirit of the present application shall fall within the protection scope of the present application.
