During the actual installation of the front wheel 2 on the front fork assembly 3 through the first quick release assembly 1, a loose state is formed between the lock nut 104 and the shaft 106 of the first quick release assembly 1, so that the shaft 106 of the first quick release assembly 1 can be arranged on the front fork, wherein a part of the front fork assembly 3 can be accommodated between one adjacent shaft sleeve 105 and one connecting plate 101, and the clamping convex part 102 of any one connecting plate 101 is larger than a preset distance relative to the clamping distance between one clamping groove part 301 on the front fork assembly 3; at this time, the handle 107 and/or the lock nut 104 may be rotated, wherein the handle 107 may drive the shaft 106 to rotate, so that the connecting sheet 101 located at the handle 107 gradually approaches the front fork assembly 3, and finally the connecting sheet 101 can be attached to the front fork assembly 3, and the locking protrusion 102 of the connecting sheet 101 may be locked into one of the locking groove portions 301 of the front fork assembly 3; and gradually approaching the connecting piece 101 at the locking nut 104 to the front fork assembly 3, and finally enabling the connecting piece 101 to be attached to the front fork assembly 3, wherein the clamping convex part 102 of the connecting piece 101 can be clamped into another clamping groove of the front fork assembly 3. When the two connection pieces 101 are respectively engaged in one of the slot portions 301, a engagement pitch of the engagement projection 102 of any one of the connection pieces 101 with respect to the engaged slot portion 301 is smaller than a preset pitch. Thereafter, continuing to rotate the handle 107 and/or the lock nut 104, when the lock nut 104 is locked relative to the shaft 106, the handle 107 may be flipped over such that the handle 107 is locked relative to the shaft 106 (see fig. 2 and 3). It should be understood that the handle 107 and the shaft 106 are hinged in an eccentric manner, that is, a distance is left between the hinge on the handle 107 and the center of the handle 107; when the handle 107 and the shaft 106 are in the unlocked state, the distance between the handle 107 and the connecting piece 101 is relatively large, whereas when the handle 107 and the shaft 106 are in the locked state, the distance between the handle 107 and the connecting piece 101 is relatively small. When the lock nut 104 is locked with respect to the shaft 106, the lock nut 104 may contact one of the coupling pieces 101 in the axial direction of the wheel, so that the coupling piece 101 is clamped by the lock nut 104 and the front fork member; similarly, when the handle 107 is locked with respect to the shaft 106, the handle 107 can contact the other connecting piece 101 in the axial direction of the wheel, so that the connecting piece 101 is clamped by the handle 107 and the front fork member.

Preferably, in the locking process of the locking nut 104 and the shaft 106, in order to avoid the locking nut 104 from damaging the connecting sheet 101, a gasket or a cushion block can be additionally arranged between the locking nut 104 and the connecting sheet 101; and, in the locking process of handle 107 and axle 106, in order to avoid handle 107 to cause the injury to connecting piece 101, can add the gasket or the cushion between handle 107 and connecting piece 101. The washer and the spacer should have a through hole for the shaft 106 to penetrate through, respectively, and the end surface of the washer or spacer should be slightly larger than the end surface of the lock nut 104, or the contact surface of the handle 107 contacting the washer or spacer should be located within the maximum profile of the end surface of the washer or spacer when the handle 107 contacts the washer or spacer.

During the actual detachment of the front wheel 2 relative to the front fork assembly 3 by means of the first preferred quick release assembly 1, the user can hold the lock nut 104 with one hand and flip the handle 107 relative to the shaft 106 with the other hand (see fig. 2 and 3) so that the handle 107 is turned from the locked state to the loose state relative to the shaft 106; the user's one hand grips the lock nut 104 while the user's other hand turns the handle 107 so that the lock nut 104 is turned from the locked state to the loosened state with respect to the shaft 106; the user continuously turns the knob 107 or the lock nut 104 so that the lock nut 104 and one of the connection pieces 101 are changed from the contact state to the non-contact state in which the one of the connection pieces 101 is brought into a movable state relative to the front fork assembly 3 in the axial direction of the wheel, and the knob 107 and the other of the connection pieces 101 are changed from the contact state to the non-contact state in which the other of the connection pieces 101 is brought into a movable state relative to the front fork assembly 3 in the axial direction of the wheel; during the process of continuously rotating the lock nut 104 and/or the handle 107, the user can pull the two connecting plates 101 along the axial direction of the wheel respectively with both hands, when the clamping distance between the clamping protrusion 102 of any one connecting plate 101 relative to one clamping groove 301 of the front fork assembly 3 is larger than the preset distance, the quick release assembly 1 is in a separable state relative to the front fork assembly 3, and at this time, the user can detach the combination of the wheel and the quick release assembly 1 relative to the front fork assembly 3 along the radial direction of the front wheel 2.

In the first preferred quick release assembly 1, the connecting piece 101 can be configured as follows:

in a first structure, referring to fig. 11, the coupling through-hole 103 of the coupling piece 101 is provided as a circular through-hole so that the shaft 106 and the coupling piece 101 form a rotatable coupling relationship when the shaft 106 penetrates the circular through-hole of the coupling piece 101.

In a second structure, referring to fig. 10, the connection through-hole 103 of the connection piece 101 is provided as a kidney hole. The kidney holes are to be understood as: the device comprises two straight line profiles which are parallel to each other and two arc profiles, wherein the arc profiles are minor arcs; or a straight line profile and an arc profile, wherein the arc profile is a major arc. Planes are respectively processed at two ends of the shaft 106 corresponding to the connecting piece 101 with the waist hole, wherein if the waist hole has two straight line profiles, two planes are respectively arranged at two ends of the corresponding shaft 106, and if the waist hole only has one straight line profile, at least one plane is respectively arranged at two ends of the corresponding shaft 106, so that one plane is attached to one straight line profile of the waist hole, and the connecting piece 101 can form a connection relation for preventing rotation relative to the shaft 106 in such a way. When the connecting piece 101 with the waist hole and the corresponding shaft 106 with the plane are simultaneously arranged in the quick release assembly 1 and the wheel is arranged on the front fork assembly 3 through the quick release assembly 1, the clamping protrusion 102 is clamped into the clamping groove 301, so that the shaft 106 forms a rotation stopping function relative to the front fork assembly 3 through the connecting piece 101 with the waist hole and the clamping protrusion 102.

In the first preferred quick release assembly 1, the connecting plate 101 lacks a positioning structure relative to the front fork assembly 3, so that the user needs to adjust the position of the connecting plate 101 relative to the front fork assembly several times to allow the locking protrusion 102 of the connecting plate 101 to be locked into the locking groove 301 of the front fork assembly 3. To solve this problem, a positioning groove 303 (see fig. 5) may be provided at the notch portion 301 of the front fork assembly 3, wherein the contour of the positioning groove 303 should match the contour of the connecting piece 101, when the connecting piece 101 is disposed in the positioning groove 303, the catching portion 102 on the connecting piece 101 may be caught in the notch portion 301 on the front fork assembly 3, and the maximum contour of the connecting piece 101 and the contour of the positioning groove 303 form a gap connection state. It should be understood that the connecting piece 101 may be provided in a variety of shapes, so as to obtain a variety of different connecting piece 101 profiles, for example: square profiles, circular profiles, hexagonal profiles, etc. Correspondingly, the contour of the positioning groove 303 should match the contour of the connecting lug 101. It should be understood that the positioning contour and the card slot portion 301 may be the same or different, i.e., the contour of the card slot portion 301 on the surface of the front fork assembly 3 is actually a portion of the contour of the positioning groove 303, or the contour of the card slot portion 301 on the surface of the front fork assembly 3 and the contour of the positioning groove 303 are isolated from each other.

It should be appreciated that the first preferred quick release assembly of this embodiment may be used in its entirety as a stand alone accessory for the assembly of a wheel and fork in the scooter art.

It should be appreciated that the first preferred quick release assembly and the front wheel of the present embodiment may comprise a wheel assembly, and the wheel assembly may be used as a single component for mounting on a front fork in the field of scooters.

In this embodiment, a second preferred quick release assembly 1 is provided, which specifically includes:

referring to fig. 8, 9, 11-14, the quick release assembly 1 includes a first connecting member 11 and a second connecting member 12;

the first connecting part 11 and the second connecting part 12 respectively comprise connecting pieces 101, wherein the connecting piece 101 in the first connecting part 11 is a first connecting piece, and the connecting piece 101 in the second connecting part 12 is a second connecting piece;

the first coupling part 11 and the second coupling part 12 are detachably coupled, in which the two catching projections 102 are disposed to face each other.

The first preferred quick release assembly 1 comprises a shaft 106, two shaft sleeves 105, two connecting pieces 101, a lock nut 104, a handle 107, a gasket or a cushion block and the like, when the user removes the combination of the front wheel 2 and the first preferred quick release assembly 1, the user can loosen the lock nut 104 relative to the shaft 106 by screwing the lock nut 104 and/or the handle 107, and the loosening distance of the lock nut 104 is larger than the preset distance between the locking protrusion 102 of the connecting piece 101 and the locking groove 301 of the front fork, however, the connection piece 101 is not always separable from the front fork assembly 3 due to the frictional force between the catching portion 102 and the catching portion 301, and generally, the user needs to manually separate the connection piece 101 from the front fork assembly 3, which results in a low efficiency of detachment of the first preferred quick release assembly 1.

The second preferred quick release assembly 1 of the present embodiment is improved on the basis of the first preferred quick release assembly 1, wherein the first connecting part 11 and the second connecting part 12 are made by taking two connecting pieces 101 as cores, but all parts of the first connecting part (including the first connecting piece thereof) are inseparable, and all parts of the second connecting part 12 (including the second connecting piece thereof) are also inseparable; the catching protrusion 102 of the first connecting piece is disposed to face the catching protrusion 102 of the second connecting piece when the first and second connecting

parts

11 and 12 are assembled together, however, as the first and second connecting

parts

11 and 12 are gradually separated during disassembly, the distance between the first and second connecting pieces may be increased. When the front wheel 2 is arranged on the front fork assembly 3 through the second preferred quick release assembly 1, along with the gradual reduction of the distance between the first connecting part 11 and the second connecting part 12, the clamping convex part 102 of the first connecting piece and the clamping convex part 102 of the second connecting piece can be respectively clamped into the two clamping groove parts 301 of the front fork assembly 3, and when the first connecting part 11 and the second connecting part 12 are locked with each other, the first connecting piece and the second connecting piece are respectively tightly attached to the front fork assembly 3 (if the front fork assembly 3 is provided with the positioning groove 303, the first connecting piece and the second connecting piece are respectively clamped and tightly attached to the positioning groove 303); conversely, when the first connecting part 11 and the second connecting part 12 are disassembled, as the distance between the first connecting part 11 and the second connecting part 12 gradually increases, the distance between the first connecting piece and the second connecting piece gradually increases until the catching protrusion 102 of the first connecting piece and the catching protrusion 102 of the second connecting piece respectively disengage from the two catching groove portions 301 on the front fork assembly 3.

As can be seen from the above, with the second preferred quick release assembly 1, in the actual assembling and disassembling process, the distance between the locking protrusion 102 of the first connecting piece and the locking protrusion 102 of the second connecting piece can be changed along with the change of the distance between the first connecting part 11 and the second connecting part 12, so that the situation that a user separates the two connecting pieces 101 from the front fork assembly 3 by a manual method can be avoided, and the disassembling efficiency of the combination of disassembling the front wheel 2 and the quick release assembly 1 from the front fork assembly 3 is at least improved.

Conversely, during the process of disassembling the front wheel 2, the second preferred quick release assembly 1 and the front fork assembly 3, as the distance between the first connecting part 11 and the second connecting part 12 increases, the first connecting piece still tightly fits on the front fork assembly 3 under the action of the first coil spring 110; continuing to increase the spacing between the first and

second connection parts

11 and 12 such that the first helical spring 110 transitions from the compressed state to the natural state, at which time the first connecting piece remains attached to the front fork assembly 3; and then, the distance between the first connecting part 11 and the second connecting part 12 is increased, the first connecting piece is gradually separated from the front fork assembly 3 under the pulling of the lock nut 104, the first sleeve 111 and the first coil spring 110, in the process, the clamping distance of the clamping projection 102 of the first connecting piece relative to one of the clamping groove parts 301 of the front fork assembly 3 is changed, and when the clamping distance is larger than the preset distance, the clamping projection 102 of the first connecting piece and one of the clamping groove parts 301 of the front fork assembly 3 are separated.

It will be appreciated that the first connecting member of this embodiment may be used alone as an accessory which may be used in a scooter to engage a front fork having a bayonet portion so that the wheel is secured to the front fork by the accessory.
