And a damping force is formed between the pin shaft 31 and the core shaft 32, so that the relative displacement between the pin shaft 31 and the core shaft is limited, the stability of the locking pin is improved, and the locking pin does not lose efficacy. Meanwhile, the core shaft 32 is provided with an ejection inclined surface, so that the locking structure 33 is more stable in locking and is not easy to lose efficacy.

When the motor quick-change structures at the motor end and the driven end are locked and connected by using the locking pin, the first magnetic coupling 11 at the motor end is aligned with the second magnetic coupling 21 at the driven end, and meanwhile, the first positioning structure 121 (positioning convex ring), the second positioning structure 221 (positioning hole), the locking pin 14 (spring locking pin) and the butt mark 28 are aligned, and are rotated to the position after being fastened in place, and then the core shaft 32 is controlled to move in the axial direction to enable the locking structure 33 of the spring locking pin to be in an unlocked state, so that the locking end 141 of the locking pin extends into the locking positioning hole 223 (the structure of the shifting piece 142 can be used, and the locking can also be realized by using the elastic piece between the locking pin body 140 and the inner wall of the pin hole); then the mandrel 32 is released, the restoring force of the damping structure 34 resets the mandrel 32, the locking structure 33 moves out of the accommodating groove 321 and is ejected into the locking port 312, the locking state is switched to be the locking state, the locking structure 33 is locked, part of the locking structure protrudes out of the outer side wall of the pin shaft 31, the protruding part of the locking structure 33 is clamped on a clamping table structure in the locking positioning hole 223 of the locking sleeve, and therefore butt joint and locking of the motor quick-change structures of the motor end and the driven end can be achieved. When unlocking is needed, the control mandrel 32 moves in the axial direction to enable the locking structure 33 of the spring locking pin to be in an unlocking state, the locking end of the spring locking pin is controlled to exit from the locking positioning hole 223, and meanwhile, when the spring locking pin rotates reversely until the spring locking pin is aligned with the butt joint mark 28, the motor quick-change structure of the motor end and the driven end is disengaged, namely, the motor 10 is quickly disassembled. Therefore, the spring locking pin of the embodiment of the disclosure has the advantages of simple structure, simple operation, high efficiency, high stability, no failure and strong universality. Can be suitable for the glove box, and has no influence on other operation activities in the glove box.

In the spring locking pin of the embodiment of the present disclosure, when the locking structure 33 is in the locking state, a part of the locking structure protrudes from the outer sidewall of the pin 31. The locking action of the protruding portion is utilized to connect the two members to be locked. Therefore, optionally, a catch structure 224 is provided on the inner wall of the locking positioning hole 223, and cooperates with the locking structure 33 of the spring locking pin to realize locking.

In the spring locking pin of the embodiment of the present disclosure, optionally, when the damping structure 34 is not deformed, the locking structure 33 is in a locked state; the locking structure 33 can be switched to the unlocked state when the operating spindle 32 is moved in the axial direction to bring about a certain deformation of the damping structure 34. Namely, when the locking pin locks the motor end and the driven end, the damping structure 34 has no deformation, so that the instability of the mandrel 32 caused by the elastic restoring force of the damping structure 34 is avoided, the locking stability is ensured, and the connection effectiveness is improved.

In this embodiment, when the locking structure 33 is switched from the locked state to the unlocked state, the core shaft 32 may be pressed inward, so that the accommodating groove 321 moves inward along the axial direction to coincide with the locking opening 312, and the locking structure 33 is unlocked, which defines the spring locking pin as a press-type locking pin (see fig. 7 to 9). The mandrel 32 may also be pulled outward, so that the receiving groove 321 moves outward along the axial direction to coincide with the locking opening 312, and the locking structure 33 is unlocked, thereby defining the spring locking pin as a pull-type locking pin (see fig. 10 to 15). The pulling or pushing can be selected according to the position of the receiving groove 321.

Here, the second axial end 314 of the pin 31 refers to an end of the pin 31 on the same side as the end 323 of the core shaft 32. At this point, the deformation of the damping structure 34 is a stretching when the mandrel 32 is pulled; the deformation of the damping structure 34 is compression when the mandrel 32 is pressed.

The unlocking of the spring locking pin is realized by stretching the core shaft 32 or pressing the core shaft 32, which is determined according to the relative positions of the accommodating groove 321 on the core shaft 32 and the locking opening 312 on the pin shaft 31, and the arrangement mode of the damping structure 34 between the pin shaft 31 and the core shaft 32.

When the mandrel 32 is pulled out, the damping structure 34 is compressed, the receiving groove 321 moves toward the first axial end 313 to approach the locking opening 312, and when the damping groove coincides with the locking opening 312, the damping structure is unlocked.

In some embodiments, as shown in fig. 7 and 8, and fig. 14 and 15, when the locking structure 33 is in the locked state, the side wall portion of the mandrel 20 that interferes with the locking structure 33 is sloped to serve as the ejection slope 3210. The arrangement of the ejection inclined surface 3210 facilitates ejection of the locking structure 33, does not retard movement of the core shaft 32, and can buffer the extrusion force of the radial external force on the locking pin to a certain extent, thereby reducing the damage probability. In this embodiment, the shape of the second sidewall of the receiving groove 321 away from the locking structure 33 is not limited, as long as the locking structure 33 is received in the receiving groove and does not fall out of the receiving groove 321.

In some embodiments, as shown in fig. 7 to 9, and fig. 13 and 14, the receiving groove 321 is a receiving ring groove disposed along the peripheral wall of the core shaft 32.

Such a stepped ramp can assist in locking the locking structure 33, even if a greater pressure is applied to the second axial end 314 of the pin 31, to cushion the pressure and reduce the chance of damage to the spindle 20.

In some embodiments, the included angle between each step surface of the inclined ejecting surface 3210 and the axial direction decreases along the direction from the bottom of the receiving groove 321 (receiving groove) to the groove edge. The locking effect and the buffering effect are better.

As shown in fig. 13, the inclined ejection surface 3210 includes two steps, and an included angle between a step surface close to the groove edge (i.e., the outer sidewall of the mandrel) and the axial direction is smaller than an included angle between a step surface close to the groove bottom and the axial direction.
