Pivot mechanism arranged between power-receiving member and main body of vehicular electric appliance

A vehicular electric appliance, comprising:

• a power-receiving member for being incorporated with a DC power source and having on one end thereof a ring member with a first teeth set on the peripheral surface thereof and a passage in a center portion thereof;
• a main body having a humpback bridge over a surface thereof for supporting said ring member, said humpback bridge having a second teeth set engageable with said first teeth set on a face thereof opposite to said surface of said main body, spaced from said surface of said main body to leave a vacancy therebetween, and being resilient and flexible;
• a positioning base coupled with said main body and having a positioning hole;
• and
• a shaft penetrating through said passage and said positioning hole for incorporating said power-receiving member with said positioning base, and serving as a pivoting axis for a pivoting operation of said power-receiving member relative to said main body,
• wherein said resilient and flexible humpback bridge is temporarily pushed toward said vacancy to have said second teeth set disengage from said first teeth set by pivoting said power-receiving member, and recovers to have said second teeth set re-engage with said first teeth set when said power-receiving member reaches to a position at a specific angle with said main body.

An angle-adjustable apparatus for adjusting an angle between a power-receiving member and a main body of a vehicular electric appliance, comprising:

• a first curved member connected to one of said power-receiving member and said main body, and having a first engaging element thereon;
• a second curved and hollow member connected to the other of said power-receiving member and said main body, made of a resilient and flexible material, and having a second engaging element of a configuration complying with said first engaging element on a face thereof opposite to the hollow vacancy;
• and
• a coupling member connecting said first curved member with said second curved and hollow member by allowing said first engaging element to engage with said second engaging element, and including a shaft penetrating through said first curved member for allowing said first curved member to pivot about said shaft and move relative to said second curved and hollow member, thereby adjusting an angle between said power-receiving member and said main body;
• wherein said first engaging element disengages from said second engaging element in response to an external force, deforms said second curved and hollow member when said external force conducts the movement of said first curved member relative to said second curved and hollow member, and then engages with said second engaging element to fix said angle between said power-receiving member and said main body.
