In the embodiment of the present disclosure, specific structures of the spring locking pin that can be adopted in the quick-change structure of the motor in the embodiment of the present disclosure are described with reference to fig. 5 to 14. The spring locking pin comprises a pin shaft 31, a mandrel 32, a locking structure 33 and a damping structure 34. The pin shaft 31 is axially provided with a shaft hole 311, and the side wall of the pin shaft 31 is provided with a locking port 312; the mandrel 32 is movably arranged in the shaft hole 311 of the pin shaft 31, and the side wall of the mandrel 32 is provided with an accommodating groove 321; the locking structure 33 is arranged in the locking port 312, and the mandrel 32 can move in the axial direction, so that the locking structure 33 is switched between an unlocking state and a locking state; the damping structure 34 is disposed between the pin 31 and the spindle 32, and defines a relative displacement between the pin 31 and the spindle 32. When the accommodating groove 321 of the core shaft 32 coincides with the locking port 312 of the pin shaft 31, the locking structure 33 is in an unlocked state; when the side wall of the core shaft 32 is opposite to the locking opening 312 of the pin 31, the locking structure 33 is in a locking state and partially protrudes from the outer side wall of the pin 31. And when the locking structure 33 is in the locked state, the side wall portion of the locking structure 33 contacting the core shaft 32 is inclined as the ejection inclined surface 320. The pin 31 is fixedly arranged on the bottom plate 11, and the locking end protrudes out of the side surface of the bottom plate 11 connected with the driven assembly 20.

The spring locking pin of the embodiment of the present disclosure splits the locking pin structure into two parts, the core shaft 32 and the pin shaft 31 having the shaft hole 311 enable the core shaft 32 and the pin shaft 31 to move axially relative to each other, and further, the receiving groove 321 is designed on the core shaft 32 to release the locking state of the locking structure 33, so that the locking structure 33 can return into the receiving groove 321 to unlock, and the locking pin can be conveniently inserted into or withdrawn from the second locking structure 23 (locking sleeve) of the motor quick-change structure at the driven end. 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 locking pin is used for locking and connecting the motor quick-change structures at the motor end and the driven end, the output structure 123 at the motor end is aligned with the input structure 21 at the driven end, the first positioning structure 13 (positioning convex ring) and the second positioning structure 22 (positioning hole), the first locking structure 14 (spring locking pin) and the second locking structure 23 (locking sleeve) are aligned, the mandrel 32 is controlled to move axially to enable the locking structure 33 of the spring locking pin to be in an unlocked state, after the two are fastened and in place, the mandrel 32 is released, the mandrel 32 is reset by the restoring force of the damping structure 34, the locking structure 33 is moved out of the accommodating groove 321 and ejected into the locking port 312 to be switched into a locked state, the locking structure 33 is locked and partially protrudes out of the outer side wall of the pin shaft 31, and the protruding part of the locking structure 33 is clamped on a clamping table structure in the second locking structure 23 of the locking sleeve, the butt joint and the locking of the motor quick-change structures at the motor end and the driven end can be realized. When unlocking is needed, the control core shaft 32 moves in the axial direction to enable the locking structure 33 of the spring locking pin to be in an unlocking state, the motor quick-change structure at the motor end and the motor quick-change structure at the driven end are disengaged, and therefore the quick disassembly of the motor 10 is completed. 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, 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. 5 to 7). 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-out locking pin (see fig. 8 to 13). The pulling or pushing can be selected according to the position of the receiving groove 321. Further, depending on the arrangement of the damping structure 34 between the pin 31 and the mandrel 32, the damping structure 34 may be compressed or stretched when the mandrel 32 is pulled or pressed, but is not limited thereto.

In some embodiments, as shown in connection with fig. 9, the connection location of the damping structure 34 to the mandrel 32 is located at the end 323 side of the mandrel 32 and the connection location to the pin 31 is located at the first axial end 313 of the pin 31. Here, the end 323 of the mandrel 32 is the other end opposite to the operating end 322 of the mandrel 32, while the operating end 322 of the mandrel 32 refers to one end for operating (drawing or pressing) the mandrel 32 to move in the axial direction, and the first shaft end 313 of the pin shaft 31 refers to one end of the pin shaft 31 on the same side as the operating end 322 of the mandrel 32. At this point, the deformation of the damping structure 34 is compression when the mandrel 32 is pulled; the deformation of the damping structure 34 when pressing the mandrel 32 is a stretching.

In some embodiments, as shown in connection with fig. 5, the connection location of the damping structure 34 to the mandrel 32 is located on the operating end 322 side of the mandrel 32, and the connection location to the pin 31 is located at the second axial end 314 of the pin 31. 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.

As shown in fig. 5 to 7, the connection position of the damping structure 34 and the mandrel 32 is located at the operation end 322 side of the mandrel 32, and the connection position of the damping structure 34 and the pin 31 is located at the second axial end 314 of the pin 31. When the spring locking pin is in the locked state, the receiving groove 321 is located on the side of the locking opening 312 close to the first axial end 313. When the mandrel 32 is pressed, the damping structure 34 is compressed, and the receiving groove 321 moves toward the second axial end 314 side and approaches the locking notch 312, and when the damping groove coincides with the locking notch 312, the damping structure is unlocked. The spring locking pin of the present embodiment is defined as a push-type locking pin (e.g., a push-button type locking pin).

As shown in fig. 8 to 13, the connection position of the damping structure 34 and the mandrel 32 is located at the end 323 side of the mandrel 32, and the connection position with the pin 31 is located at the first axial end 313 of the pin 31. When the spring locking pin is in the locked state, the receiving groove 321 is located at the second axial end 314 side of the locking opening 312. 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. The spring locking pin of this embodiment is defined as a pull type locking pin.

In some embodiments, the damping structure 34 comprises a spring; one end of the spring is connected to the pin 31 and the other end is connected to the spindle 32. A damping force is created between the pin 31 and the spindle 32, defining a relative displacement therebetween.

In some embodiments, as shown in fig. 5 and 6, and fig. 12 and 13, 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.

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. 11, 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.
