The working principle of the automatic power-off speed-changing safety handle of the electric vehicle is as follows:
in an initial state, the positioning block 8 is not positioned in a gap between the first conducting strip 4 and the second conducting strip 5, at this time, the first conducting strip 4 and the second conducting strip 5 are disconnected, that is, the electric vehicle transmission 11 and the electric vehicle power supply are disconnected, the electric vehicle is in a power-off state and cannot advance, when the electric vehicle needs to advance, the electric vehicle handle shell 6 is held by a hand, the modification push rod sheath 20 outside the translation push rod 1 moves the translation push rod 1 and the modification push rod sheath 20 along the dovetail groove 7 on the shell 6 towards the directions of the first conducting strip 4 and the second conducting strip 5, when a conducting component at the end part of the translation push rod 1 smoothly moves into the gap between the first conducting strip 4 and the second conducting strip 5 under the guiding of the arc-shaped guide block 10 at the end part of the positioning block 8, two sides of the conducting clamping piece 9 on the positioning block 8 just effectively contact with the first conducting strip 4 and the second, the first conducting plate 4 and the second conducting plate 5 are communicated, namely the electric vehicle transmission 11 is communicated with an electric vehicle power supply, the electric vehicle is electrified, and then the rotating sleeve 21 of the transmission 11 can be rotated by rotating the handle shell 6 within one second, so that the electric vehicle is accelerated to advance through the transmission.
In the process, when the translational push rod 1 pushes towards the gap between the first conducting strip 4 and the second conducting strip 5, because the width of the positioning block 8 is greater than the preset distance between the gaps between the first conducting strip 4 and the second conducting strip 5, when the positioning block 8 enters between the first conducting strip 4 and the second conducting strip 5 under the action of the arc-shaped guide block 10, the first conducting strip 4 and the second conducting strip 5 are respectively extruded towards two sides, so that the first spring 12 and the second spring 13 are compressed, and under the action of the resilience force of the first spring 12 and the second spring 13, the first conducting strip 4 and the second conducting strip 5 are in close effective contact with two sides of the conducting clamping piece 9 on the positioning block 8; the effective contact between the first conducting strip 4 and the first conducting support 16 is realized by extruding the first pressing block 18 to effectively contact with the first conducting strip 4 through the third spring 14, so that the first conducting strip 4 is effectively contacted with the first conducting support 16, and the first conducting strip 4 can be effectively connected with the output end of the power supply through the first conducting support 16; similarly, the effective contact between the second conducting strip 5 and the second conducting support 17 is realized by the fourth spring 15 extruding the second pressing block 19 to effectively contact the second conducting strip 5 with the second conducting support 17, so that the second conducting strip 5 can be effectively connected with the input end of the electric vehicle transmission 11 through the second conducting support 17.

When user's hand leaves handle shell 6, under the reverse thrust effect of reverse thrust spring 2, translation pushing ram 1 can reset along dovetail 7 reverse translation in a second together with decorating pushing ram sheath 20, the conductive component who drives translation pushing ram 1 tip shifts out the clearance between first conducting strip 4 and the second conducting strip 5, thereby conductive clamping piece 9 on the locating piece 8 separates with first conducting strip 4 and second conducting strip 5, first conductive 4 and the disconnection of second conducting strip 5, break off between electric motor car derailleur 11 and the electric motor car power promptly, the electric motor car outage, only rotatory handle shell 6 can't order about the electric motor car acceleration forward this moment.
The design adds the translation push rod 1, the power line separation mechanism and the reverse push spring 2 on the basis of not changing any function of the electric vehicle rotating speed handle, so that the electric vehicle handle can be automatically connected with a power supply within one second to accelerate to advance; and the power can be cut off in one second after nobody holds, and no matter how the handle of the electric vehicle is rotated by a child after the power is cut off, the electric vehicle can never advance, so that the occurrence of an injury event caused by misoperation of the handle by the child is effectively avoided.
The above embodiments are merely illustrative of the technical concepts and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
