Abstract

L'invention concerne un dispositif de détection de couple (1) sur un essieu arrière et un vélo électrique. Le dispositif de détection (1) comprend un siège de fixation de détecteur (10) pour un détecteur (20) et un manchon de fixation (50) pour une pièce magnétique (30). Le siège fixe de détecteur (10) peut être relié d'une seule pièce à la fourche (2) du vélo électrique. Le manchon de fixation (50) peut être relié d'une seule pièce à l'essieu arrière (3) du vélo électrique. En raison de la liaison par glissement entre le siège fixe de détecteur (10) et le manchon de fixation (50), le manchon de fixation (50) peut se déplacer avec l'essieu arrière (3) par poussée du pied, alors que le siège fixe de détecteur (10) et la fourche (2) restent fixes. Par conséquent, l'état du manchon de fixation (50) et de l'essieu arrière (3) est détecté par le détecteur (20) afin de démarrer le moteur électrique pour assister la conduite manuelle. De la même manière, lorsque la poussée du pied prend fin, le manchon de fixation (50) et l'essieu arrière (3) retournent dans leur position initiale et l'état de déplacement disparaît, ce qui entraîne l'arrêt du fonctionnement du moteur électrique.
