DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0029] according to Figure 1 and Figure 2 As shown, the utility model provides an inner handle with a spring buckle structure for increasing the sense of resistance when triggering a micro switch, comprising a base 1, a side plate 2 and a pull handle 3. The base 1 is provided with a side plate 2 and a pull handle 3, and the side plate 2 is provided with a bracket assembly 4, which includes a first bracket 10 and a second bracket 11. The first bracket 10 is provided with a first through hole 12, and the second bracket 11 is provided with a second through hole 13, and a first shaft pin 5 is inserted through the first through hole 12 and the second through hole 13. The pull handle 3 is rotatably connected to the bracket assembly 4 through the first shaft pin 5. The first shaft pin 5 is sleeved with a handle torsion spring 14, one end of which contacts the side plate 2, and the other end contacts the second bracket 11. The function of this structure is to increase the sense of resistance when triggering the micro switch assembly 15, so that the inner handle is more stable during operation, and at the same time has a certain elasticity, improves the comfort of user operation, and helps to extend the service life of the inner handle.
[0030] according to Figure 3 As shown, a blocking plate 7 is provided at the bottom of the pull handle 3, and a spring sheet 9 for blocking the pull handle 3 is provided on the blocking plate 7. A deformable spring buckle 8 is provided on the base 1, and the spring buckle 8 abuts against the spring sheet 9. When the pull handle 3 is operated, the spring sheet 9 can remind the passenger that the micro switch has been triggered and does not need to be opened. At the same time, a deformation groove 29 is provided on the outer side of the spring buckle 8 to provide elasticity so that the spring buckle 8 can be deformed to a certain extent. If the passenger continues to apply force to the pull handle 3, the contact surface between the pull handle 3 and the spring buckle 8 slides relative to each other, and the spring buckle 8 is deformed to achieve mechanical unlocking.
[0031] according to Figure 5 As shown, a micro switch assembly 15 is provided at one end of the base 1, and a contact piece 16 is provided on the micro switch assembly 15. In addition, a driving block 17 is provided on the pull handle 3, and the driving block 17 abuts against the contact piece 16 on the micro switch assembly 15. When the user operates the pull handle 3, the driving block 17 contacts with the contact piece 16, presses the micro switch, and sends a signal to the control system, thereby realizing the electronic door opening function.
[0032] according to Figure 4 As shown, a self-locking assembly 18 is provided at one end of the base 1 away from the micro switch assembly 15, and the self-locking assembly 18 includes a second shaft pin 6 and a self-locking arm 19 provided on the second shaft pin 6, a lock catch 20 is provided on the self-locking arm 19, and a corresponding lock groove 21 is provided on the blocking plate 7. A self-locking torsion spring 22 is sleeved on the second shaft pin 6, and a stopper 23 is provided on the self-locking arm 19. One end of the self-locking torsion spring 22 abuts against the stopper 23, and the other end abuts against the side plate 2. The lock catch 20 on the self-locking arm 19 can cooperate with the lock groove 21 on the blocking plate 7 to achieve automatic locking. The self-locking torsion spring 22 provides elasticity, so that the self-locking arm 19 can be automatically lifted and cooperate with the lock groove 21 when the door is closed, thereby ensuring the safe closing of the door.

When the door is closed, the limit block 24 will contact the buffer pad 25, which can provide a certain buffering effect, reduce the impact force generated when closing, protect the inner handle structure, and extend its service life.
[0034] When the utility model is used, in a static state, the spring catch 8 does not contact the pull handle 3. When the pull handle 3 is opened at a small angle, the handle torsion spring 14 is deformed, the drive block 17 squeezes the contact piece 16, triggers the micro switch assembly 15, and feeds back a signal to the driving computer, which executes the door opening to achieve electronic unlocking. At the same time, the spring piece 9 of the blocking plate 7 on the pull handle 3 contacts the spring catch 8. Due to the existence of the deformation groove 29, the pull handle 3 is continued to be opened at this time, and the opening force value increases suddenly. The contact surface of the pull handle 3 and the spring catch 8 slides relative to each other, the spring catch 8 deforms, the pull handle 3 is opened at a large angle, the door lock is pulled open, and mechanical unlocking is achieved. After the pull handle 3 is released, the handle torsion spring 14 resets the pull handle 3, and the limit block 24 falls on the buffer pad 25 to prevent it from being damaged due to inertia.
