Detailed Description

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses a steering locking mechanism of an aged scooter. Referring to fig. 1, the steering lock mechanism of the scooter for the aged comprises a vehicle body 1, a steering rod 2 rotatably arranged on the vehicle body 1, and a lock mechanism for interlocking between the vehicle body 1 and the steering rod 2. The locking mechanism comprises a lock rod 3 which is arranged on the vehicle body 1 in a sliding manner, a lock plate 4 which is inserted into the lock rod 3 is fixedly welded on the steering rod 2, a positioning groove 8 is formed in the lock plate 4 and used for allowing the lock rod 3 to be inserted into the lock plate 4 and locked, namely, after the lock rod 3 is driven to be inserted into the positioning groove 8 by the locking piece, the steering rod 2 is driven to rotate so as to drive the lock plate 4 to rotate, and the lock rod 3 is limited, so that the steering rod 2 is prevented from rotating, the effect of locking a steering mechanism and a front wheel is achieved, and further shaking of the steering mechanism in the transportation process is prevented.

The locking piece includes driving lever 5, and driving lever 3 tip is provided with screw thread post 31, and driving lever 5 tip is provided with the screw thread groove, and then makes driving lever 3 spiro union fixed on driving lever 5, and this kind of detachable connection is convenient for install on the one hand, but on the other hand alone is changed when the part damages. The handle 6 is arranged on the side wall of the deflector rod 5, the L-shaped locking groove 11 for the deflector rod 5 to move is arranged on the vehicle body 1, and then when the deflector rod 5 rotates, the deflector rod 5 cannot move up and down when the horizontal part of the L-shaped locking groove 11 is rotated, so that the deflector rod 5 and the lock rod 3 are locked, and when the L-shaped locking groove 11 rotates in the vertical direction, the deflector rod 5 can move up and down, so that the lock rod 3 can be pulled out from the positioning groove 8, and the unlocking effect is achieved. And the deflector rod 5 inclines towards the direction far away from the locking plate 4, so that the stability of the clamping connection of the deflector rod in the L-shaped locking groove 11 is ensured. After unlocking, in order to prevent the lock rod 3 from entering the positioning groove 8 by mistake under the action of self gravity, the spring 7 is sleeved on the deflector rod 5, two ends of the spring 7 are respectively abutted with the handle 6 and the vehicle body 1, and then the deflector rod 5 is far away from the locking plate 4 under the action of the spring 7, so that the effect that the lock rod 3 is far away from the locking plate 4 is driven.

In order to meet the special situations, for example, the space position of the interior of the transport vehicle is limited, when the front wheel needs to rotate for a certain angle to be locked, a plurality of positioning grooves 8 are arranged at equal intervals along the axial direction of the steering rod 2, so that when the steering rod 2 drives the locking plate 4 to rotate, the locking rod 3 can still be inserted into the corresponding positioning grooves 8.

The implementation principle of the steering locking mechanism of the scooter for the aged is as follows: after the locking piece drives the lock rod 3 to be inserted into the positioning groove 8, the steering rod 2 rotates to drive the locking plate 4 to rotate and is subjected to the limiting action of the lock rod 3, so that the steering rod 2 is prevented from rotating, the effect of locking the steering mechanism and the front wheel is achieved, and further shaking of the steering mechanism and the front wheel in the transportation process is prevented.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
