Vehicle-mounted easily lockable support legs

Abstract

This invention provides a vehicle support leg assembly with convenient locking, including a fixed base, a leg post, a first spring-loaded unit, a second spring-loaded unit, a first sensing unit, a second sensing unit, and a locking unit. The leg post is pivotally connected to the fixed base. The first spring-loaded unit positions the leg post at the parking angle. The second spring-loaded unit resists movement of the leg post from the parking angle to the sensing angle and returns it to its original position. When the leg post moves to the sensing angle, the first sensing unit enters the sensing range of the second sensing unit, transmitting a signal to the locking unit. A locking pin cyclically inserts into or disengages from the leg post's locking pin slot, automatically locking or unlocking. This design improves operational convenience and safety, allowing for keyless operation. Components such as springs, top blocks, and through-holes ensure stable and reliable operation of the leg post in both the parking and retracted positions. The operation is intuitive, and the structure is simplified and durable.

Claims

1. A vehicle-mounted, lockable support leg assembly, disposed in a vehicle, comprising: a fixed base disposed in the vehicle and having a first pivot; a leg post having a second pivot pivotally connected to the first pivot and a locking groove; a first spring-loaded unit disposed between the fixed base and the leg post, positioning the leg post relative to the fixed base at a parking angle position; a second spring-loaded unit disposed between the fixed base and the leg post, resisting movement of the leg post from the parking angle position to a sensing angle position, and returning the leg post to the parking angle position; a first sensing unit disposed in the second spring-loaded unit and capable of vertical displacement; and a second sensing unit disposed in the fixed base and capable of sensing the first sensing unit when the first sensing unit rises, and transmitting a sensing signal. A locking unit receives the sensing signal and has a locking pin that locks with the locking pin slot, and a driving member that drives the locking pin to move. When the locking unit receives the sensing signal, it drives the locking pin to cycle to lock and disengage from the locking pin slot of the foot post.

2. The vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The mounting base has a through hole for the pin to pass through and move.

3. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The first spring abutting unit has a first spring that abuts against the fixed base, and abutting block that abuts against the first spring and the foot post.

4. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The second spring-loaded unit has a connecting bolt, and the first sensing unit is disposed on the connecting bolt.

5. A vehicle support leg assembly that can be easily locked as described in claim 4, wherein, The second spring abutment unit has a second spring that abuts against the fixing seat and the connecting bolt.

6. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The first sensing element of the first sensing unit is a sensing magnet, and the second sensing element of the second sensing unit is a Hall sensor.

7. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The locking unit also has a third spring that pushes the locking pin to move into the locking pin slot.

8. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The foot post has a parking lower stop that abuts against the first spring stop unit.

9. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The foot post has a sensing lower abutment portion that abuts against the second spring abutment unit.

10. A vehicle support leg assembly that can be easily locked as described in claim 1, wherein, The foot post has a retractable lower abutment that abuts against the first spring abutment unit.
