Example 1

As shown in fig. 1 and 2, the present embodiment provides a pole setting expansion control mechanism 30, which may include a box structure 100, and a key structure 200 and an expansion pin structure 300 disposed on the box structure 100, wherein the key structure 200 and the expansion pin structure 300 interact, and the expansion pin structure 300 can be contracted or extended by pressing the key structure 200, so that the expansion pin structure 300 unlocks or locks other structures.

Specifically, the box structure 100 may include a box bottom plate 110, and a box cover plate 120 covering the box bottom plate 110, where the box bottom plate 110 and the box cover plate 120 enclose a locking cavity 104 and an unlocking cavity 102 that are mutually communicated. By setting the box body structure 100 to be a structure that the box body bottom plate 110 and the box body cover plate 120 are mutually covered, the locking cavity 104 and the unlocking cavity 102 are conveniently arranged between the box body bottom plate 110 and the box body cover plate 120, so that the telescopic pin structure 300 and the key structure 200 are conveniently and correspondingly arranged in the locking cavity 104 and the unlocking cavity 102 respectively.

The locking cavity 104 may be formed by forming a groove in the bottom plate 110, by forming a groove in the cover plate 120, or by forming corresponding grooves in both the bottom plate 110 and the cover plate 120. Similarly, the unlocking cavity 102 may be formed by forming a groove on the bottom plate 110 of the case, or by forming a groove on the cover plate 120 of the case, or by forming corresponding grooves on both the bottom plate 110 of the case and the cover plate 120 of the case.

In this embodiment, as shown in fig. 3 to 6, the locking cavity 104 may include a bottom locking groove 114 formed on the bottom plate 110 of the case, and a cover locking groove 124 formed on the cover 120 of the case, where the cover locking groove 124 and the bottom locking groove 114 are vertically and correspondingly communicated for accommodating and limiting the key structure 200. Similarly, the unlocking cavity 102 may include a bottom unlocking slot 112 formed on the bottom plate 110 of the box body, and a cover unlocking slot 122 formed on the cover plate 120 of the box body, where the cover unlocking slot 122 and the bottom unlocking slot 112 are correspondingly connected up and down for accommodating and limiting the telescopic pin structure 300. Moreover, the bottom plate locking groove 114 is arranged in communication with the bottom plate unlocking groove 112, and the cover plate locking groove 124 is arranged in communication with the cover plate unlocking groove 122, so that the unlocking cavity 102 is communicated with the locking cavity 104, and the key structure 200 in the unlocking cavity 102 is conveniently abutted with the telescopic pin structure 300 in the locking cavity 104.

In addition, the key structure 200 may be elastically installed in the unlocking cavity 102, and partially protrudes out of the box structure 100 and is in tight fit with the telescopic pin structure 300. Furthermore, the telescopic pin structure 300 may be elastically installed in the locking cavity 104 and partially protrude from the box structure 100. Also, when the key structure 200 is pressed, the key structure 200 may reduce the pressing action on the telescopic pin structure 300 to place the telescopic pin structure 300 in a contracted state. By arranging the key structure 200 in the unlocking cavity 102 elastically, when the part of the key structure 200 protruding out of the box body structure 100 is pressed, the elastic acting force of the key structure 200 in the unlocking cavity 102 can be overcome, so that the key structure 200 is contracted, the key structure 200 can act on the telescopic pin structure 300 which is in tight fit with the key structure 200 in the contraction process, the extrusion force on the telescopic pin structure 300 is reduced, the telescopic pin structure 300 can automatically contract under the action of self elasticity, and the part protruding out of the box body structure 100 is contracted towards the inside of the box body structure 100; when the pressing of the part of the key structure 200 protruding out of the box body structure 100 is released, the key structure 200 can reset under the action of self elasticity and protrudes out of the box body structure 100 again, the pressing force of the key structure 200 to the telescopic pin structure 300 abutted against the key structure is increased in the resetting process, and the elastic acting force of the telescopic pin structure 300 can be overcome to enable the key structure 200 to protrude out of the box body structure 100 again.

By arranging the telescopic pin structure 300 and the key structure 200 in the box body structure 100, when the key structure 200 is pressed, the extrusion action of the telescopic pin structure 300 arranged in the box body structure 100 can be reduced to shrink the telescopic pin structure, so that the telescopic pin structure 300 can unlock other structures (such as vertical rods) and can stretch and deform the other structures (such as the vertical rods); when the key structure 200 is not pressed any more, the key structure 200 will automatically reset under the action of its own elastic force to push the telescopic pin structure 300 to automatically extend, so that the telescopic pin structure 300 can fix other structures (such as the upright posts), and the shapes of the other structures (such as the upright posts) remain unchanged. Through using this kind of pole setting telescopic control mechanism on the scooter, the accessible presses and loosens button structure 200, carries out telescopic control to the structure of scooter voluntarily, can change the size of scooter simply, can make it more conveniently carry.

Further, as shown in fig. 2 and 7, the key structure 200 may include a key block structure 210 and a key reset elastic member 220 disposed in the unlocking cavity 102, the key reset elastic member 220 abuts against the bottom of the key block structure 210, the top of the key block structure 210 protrudes out of the box structure 100, and the telescopic pin structure 300 abuts against the side edge of the key block structure 210. The key reset elastic member 220 can use its own elasticity to tightly press the key block structure 210 and tightly press the telescopic pin structure 300 contacting with the key block structure 210. When the portion of the key block structure 210 protruding out of the box body structure 100 is pressed, the key block structure 210 applies pressure to the key reset elastic member 220, so that the key reset elastic member 220 overcomes the self elastic force to shrink, the elastic acting force of the key reset elastic member 220 on the key block structure 210 is reduced, the extrusion force of the key block structure 210 on the telescopic pin structure 300 is reduced, the telescopic pin structure 300 shrinks inwards towards the box body structure 100 under the action of the self elastic force, and the portion of the telescopic pin structure 300 protruding out of the box body structure 100 shrinks inwards towards the box body structure 100.

Moreover, the key block structure 210 may include a key main block 216 movably clamped in the unlocking cavity 102, and a key cap 212 disposed on top of the key main block 216, where the key cap 212 is located outside the box structure 100, the bottom of the key main block 216 abuts against the key reset elastic member 220, and the side of the key main block 216 abuts against the telescopic pin structure 300. The shape of the unlocking cavity 102 correspondingly matches the shape of the key main block 216, so that the unlocking cavity 102 can perform proper limiting and guiding on the key main block 216. In addition, the key block structure 210 may further include a key link 214 connecting the key cap 212 and the key main block 216, which facilitates the protrusion of the key cap 212 from the case structure 100 and also makes it inconvenient to transmit the force acting on the key cap 212 to the key main block 216.

The key main block 216 can be elastically abutted and limited in the unlocking cavity 102 from the bottom by the key reset elastic piece 220 arranged in the unlocking cavity 102, so that the key block structure 210 cannot be separated from the box body structure 100, and meanwhile, the key main block 216 is abutted with the telescopic pin structure 300. Moreover, the key cap 212 is disposed on top of the key main block 216 and protrudes out of the case structure 100, so that the key link 214 and the key main block 216 of the key block structure 210 can be conveniently pressed by the key cap 212. Moreover, by abutting the side edge of the key main block 216 against the telescopic pin structure 300, the telescopic pin structure 300 is located at the side edge of the key block structure 210, and the layout is more reasonable. In addition, the telescopic pin structure 300 may be provided on the same side as the key block structure 210.

As shown in fig. 3 to 6, the bottom plate unlocking groove 112 provided in the case bottom plate 110 includes a bottom plate unlocking main groove 1124 corresponding to the key main block 216, and a bottom plate unlocking through groove 1122 corresponding to the key link 214, the bottom plate unlocking through groove 1122 communicates the bottom plate unlocking main groove 1124 with the outside, the shape of the bottom plate unlocking main groove 1124 corresponds to the shape of the key main block 216, and the shape of the bottom plate unlocking through groove 1122 corresponds to the shape of the key link 214. Correspondingly, the cover unlocking groove 122 formed on the cover 120 of the box body comprises a cover unlocking main groove 1224 corresponding to the key main block 216 and a cover unlocking through groove 1222 corresponding to the key connecting rod 214, wherein the cover unlocking through groove 1222 is communicated with the cover unlocking main groove 1224 and the outside, the shape of the cover unlocking main groove 1224 corresponds to the shape of the key main block 216, and the shape of the cover unlocking through groove 1222 corresponds to the shape of the key connecting rod 214. In addition, the cross-sectional dimension of the key cap 212 and the cross-sectional dimension of the key main block 216 are both larger than the cross-sectional dimension of the key connecting rod 214 and also larger than the cross-sectional dimensions of the cover plate unlocking through groove 1222 and the bottom plate unlocking through groove 1122, so that the key main block 216 and the key cap 212 are conveniently limited, and the key cap 212 cannot enter the unlocking cavity 102, and the key main block 216 cannot be separated from the unlocking cavity 102.

In addition, as shown in fig. 7, a guide block 116/126 is protruded on one of the surface of the key main block 216 (including the upper surface and the lower surface of the key main block 216, which respectively correspond to the bottom surface of the bottom plate unlocking main groove 1124 of the case bottom plate and the bottom surface of the cover plate unlocking main groove 1224 of the case cover plate 120) and the inner wall surface of the unlocking chamber 102, a guide chute 2162/2164 is concavely provided on the other of the two, and the guide block 116/126 is slidably engaged in the guide chute 2162/2164.

In addition, at least one elastic limiting groove is formed between the bottom side surface of the key main block 216 and the inner wall surface of the unlocking cavity 102, and a key reset elastic piece 220 is arranged in each elastic limiting groove. By arranging the elastic limit groove between the bottom side surface of the key main block 216 and the inner wall surface of the unlocking cavity 102, the key reset elastic piece 220 arranged at the bottom of the key main block 216 can be limited in the elastic limit groove, so that the key reset elastic piece 220 is prevented from being deviated in the telescopic process to influence the telescopic action effect on the key main block 216. In addition, the elastic limit groove can be arranged in one or a plurality of the elastic limit grooves. In this embodiment, two elastic limiting grooves may be disposed side by side, and two key reset elastic members 220 may be disposed in the two elastic limiting grooves in a one-to-one correspondence.
