Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
see the disassembly and assembly structure of the motor vehicle wheels of children shown in Fig. 1 to 9, this disassembly and assembly structure removing and installing on children's electric motor vehicle between wheel 1 and wheel shaft 2.This detaching structure comprises and being fixedly arranged on permanent seat 3 in the middle part of wheel 1, being located on permanent seat 3 for permanent seat 3 being connected to the locking piece on wheel shaft 2.
wheel 1 comprises wheel hub and tire 101, wherein the wheel hub wheel cap 104 that comprises inner wheel hub 102, outer wheel hub 103 and be fixedly mounted on inner wheel hub 102, and the center position of inner wheel hub 102 is located at regularly by permanent seat 3, and permanent seat 3 and wheel 1 concentric are arranged.
shown in Figure 2, permanent seat 3 offers the mounting hole 31 that can pass axially through for wheel shaft 2, the end of wheel shaft 2 offers circular groove 21.Locking piece can be located on permanent seat 3 along wheel shaft 2 with radially sliding, and permanent seat 3 offers the mounting groove 32 for installing locking piece, locking piece is plugged in mounting groove 32 slidably along the radial direction of wheel shaft 2.
this locking piece comprises locking plate 5, for providing locking plate 5 along the elastic component 6 of its direction of slip elastic-restoring force.Locking piece 5 comprises locking part 51 in the form of sheets, and this locking part 51 offers lock slots 52, and the groove footpath of this lock slots 52 is greater than the diameter of wheel shaft 2, thus can pass along axial sliding movement for wheel shaft 2.What elastic component 6 adopted is spring, and one end locking plate 5 being positioned at locking part 51 is provided with connecting portion 53, and one end of spring to be set on connecting portion 53 and to be pressed on locking part 51, and the other end of spring is pressed on the cell wall of mounting groove 32.
when wheel 1 is arranged on wheel shaft 2, wheel shaft 2 passes axially through the mounting hole 31 on permanent seat 3 and the lock slots 52 on locking plate 5, and now locking piece has lock-out state and released state.When locking piece is in the lock state, see shown in Fig. 4 to Fig. 6, under the elastic acting force of spring 6, locking plate 5 is compressed, lock slots 52 have at least part edge be fastened in the circular groove 21 of wheel shaft 2 end, and lock slots 52 is pressed on the cell wall of circular groove 21 near the cell wall of spring 6 side along the radial direction of wheel shaft 2, like this, wheel shaft 2 is under locked sheet 5 is limited to this position vertically, wheel 1 and wheel shaft 2 is made to realize axial limit mounting, due to the effect of spring 6 elastic-restoring force, under locking piece is stably in above-mentioned lock-out state.
when locking piece unlocks, then need the elastic acting force overcoming spring 6, locking plate 5 is slided away from wheel shaft 2 along the radial direction of wheel shaft 2, thus the circumferential edge of lock slots 52 is all separated with circular groove 21.
shown in each accompanying drawing, this disassembly and assembly structure also comprises the unlock piece 4 for unlocking locking piece, and herein, what this unlock piece adopted is unlock button 4, this unlock button 4 is located at the outer end of permanent seat 3, and unlock button 4 is arranged slidably along the direction of axis line being parallel to wheel shaft 2 on permanent seat 3.
locking plate 5 is also provided with and separates lock section 54, this solution lock section 54 has two, is located at the both sides being positioned at locking part 51 respectively, and each solution lock section 54 all has guiding surface a.Unlock button 4 has the unblock inclined-plane b matched with guiding surface a, see shown in Fig. 7 to Fig. 9, when there being external force to order about unlock button 4 along axially the sliding towards locking plate 5 of wheel shaft 2, unlock inclined-plane b to match with guiding surface a, and then order about locking plate 5 and overcome the elastic force of spring 6 and the radial direction along wheel shaft 2 is slided away from wheel shaft 2, like this, the lock slots 52 on locking plate 5 just can be made to depart from circular groove 21, and then locking piece is unlocked, wheel 1 can be disassembled from wheel shaft 2 by user.
to sum up, after adopting above-mentioned disassembly and assembly structure, when wheel 1 is mounted on wheel shaft 2 by needs, user only needs wheel 1 to penetrate on wheel shaft 2 through axle hole, wheel shaft 2 passes axially through the mounting hole 31 of permanent seat 3, the end of wheel shaft 2 is in the process penetrating lock slots 52, time initial, spring 6 is extruded and locking plate 5 is slided away from wheel shaft 2, when circular groove 21 position on wheel shaft 2 arrives lock slots 52 place, spring 6 promotes locking plate 5 and slides towards wheel shaft 2, thus make at least part of edge of lock slots 52 snap in circular groove 21, make the side cell wall of lock slots 52 be pressed on the cell wall of circular groove 21 simultaneously, so just, achieve the locking of locking piece, and then wheel 1 is mounted on wheel shaft 2.When wheel 1 disassembles by needs, user only needs being unlocked by pressing button 4, unlock button 4 slides towards locking plate 5 vertically, unblock inclined-plane b on unlock button 4 matches with the guiding surface a on locking plate 5 and orders about locking plate 5 along the direction away from wheel shaft 2 and slides, and then locking piece is unlocked.Above-mentioned disassembly and assembly structure is simple, and the operation of the installation and removal of wheel is all very simple and convenient, saves the set-up time of wheel during children's electric motor vehicle assembling.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
