Detailed description of the invention
Existing magnetic bar toy dolly is during advancing, and the magnetic bar model built on cart base plate is susceptible to
Cave in, and child is also easily damaged by the connection bearing 3 that metal is made.To this, the utility model proposes a kind of magnetic
Power stick toy cart base plate assembly.
Below in conjunction with embodiment and figure, the utility model is described in further detail, but embodiment party of the present utility model
Formula is not limited only to this.
Embodiment one: as shown in Figures 1 to 3, a kind of magnetic bar toy cart base plate assembly, including base plate body 1 and car
Wheel 2, wheel 2 is rotationally connected with base plate body 1 by connecting bearing 3, connects bearing 3 and includes: many and base plate body 1 company of fixing
The supporting section 4 connect, the both ends of supporting section 4 axially offering inserting groove 6 and being formed slotting at the end face of supporting section 4 along himself
Interface；Damping section 5, is coaxially disposed with wheel 2, and the wherein one end of damping section 5 is rotationally connected with wheel 2, and the other end extend into
With supporting section 4 grafting in inserting groove 6；It is provided with on the sidewall of inserting groove 6 for locking damping section 5 to prevent it from skidding off inserting groove
The fixture block 8 of 6, circumferentially disposed preferably in annular and around inserting groove 6 of above-mentioned fixture block 8.It is provided with and card on the sidewall of damping section 5
The draw-in groove 9 that block 8 is corresponding, accordingly, draw-in groove 9 is also in circular.Formed between sidewall and the sidewall of inserting groove 6 of damping section 5
Have cushion chamber 10, the sidewall of damping section 5 and/or the sidewall of inserting groove 6 are provided with for bumper and absorbing shock section 5 and supporting section 4 it
Between the resilient snubber of relative motion.
Technique scheme, the wheel 2 of toy car is rotationally connected with base plate body 1 by connecting bearing 3.Owing to connecting

When wheel 2 crosses rugged ground, the vibrations of wheel 2 are delivered in damping section 5, due to the effect of elastic buffer, wheel 2
Amplitude and the dynamics of vibrations are significantly reduced, and improve cart base plate stationarity in the process of moving, it is to avoid build with little
Magnetic bar toy model on car bottom plate caves in.
Describe in detail, as it is shown on figure 3, damping section 5 rotates even with wheel 2 more than it near one end diameter of inserting groove 6 diapire
Connecing the diameter of one end, damping section 5 abuts against with the sidewall of inserting groove 6 near the sidewall of one end of inserting groove 6 diapire.Above-mentioned technology
Scheme, the only sidewall of part damping section 5 abut against with inserting groove 6, also allow for toy car in the case of smooth-ride,
Damping section 5 can be coaxial with supporting section 4, it is to avoid toy car is sent out due to the effect of resilient snubber self during advancing
Raw vibrations.Only when toy car drives to irregular ground, resilient snubber just works.As it is shown on figure 3, damping section
5 are divided into 2 joints, and wherein the joint diameter near inserting groove 6 diapire is suitable with the internal diameter of inserting groove 6, and another connected with wheel 2
Save then diameter less, between the outer wall and the sidewall of inserting groove 6 of this joint, form described cushion chamber 10.
For the selection of above-mentioned resilient snubber, including multiple shell fragments or elastic projection 11, multiple shell fragments or elastic projection
11 are uniformly distributed setting along the circumference of inserting groove 6.In the present embodiment, preferred resilient snubber is elastic projection 11, elastic
Projection 11 and inserting groove 6 inwall or the one-body molded setting in lateral wall of damping section 5.Above-mentioned setting, can bumper and absorbing shock effectively
Relative motion between section 5 and supporting section 4, reduces toy car and advances to the vibration amplitude of base plate during out-of-flatness ground.
In order to avoid the wheel 2 of toy car is by landing in damping section 5, further, as it is shown in figure 1, damping section 5 and car
The one end that connect of wheel 2 reach the wheel 2 side away from base plate body 1 through wheel 2 core wheel, and threaded have one for
Prevent the nut 12 of wheel 2 landing from damping section 5.
In order to avoid the wheel 2 of toy car produces friction with the edge of base plate body 1, hinder toy car motion, subtract
It is provided with the limiting plate 13 for limiting wheel 2 position on the shake section 5 sidewall between wheel 2 and base plate body 1.Limiting plate
13 in annular and fixed cover is located on the sidewall of damping section 5.
Optimize, damping section 5 and being circumferentially provided with for placing along damping section 5 sidewall on the sidewall of wheel 2 joint
The placing trough 14 of wheel 2.By arranging placing trough 14, can further wheel 2 be carried out spacing, prevent it along damping section
The axially-movable of 5, promotes the stability of wheel 2 motion.
As it is shown in figure 1, offer the fixing groove (7) for placing magnetic bar, supporting section 4 on the whole on base plate body (1)
Quantity be two and setting direction perpendicular with the length direction of base plate body 1, supporting section 4 is positioned at the bottom of base plate body 1
And the center line along base plate body 1 length direction is symmetricly set in the two ends of base plate body 1.Supporting section 4, damping section 5, base plate are originally
Body 1 is all made of plastics, and supporting section 4 and base plate body 1 all use integrated injection molding so that cart base plate processing is more square
Just, structure is the compactest.
Embodiment two: as shown in Figure 1, Figure 2 and Figure 4, a kind of magnetic bar toy cart base plate assembly, with the district of embodiment one
It is not: be additionally provided with for bumper and absorbing shock section 5 along himself axially-movable between the diapire and damping section 5 of inserting groove 6
Elastic blob of viscose 15.Having the beneficial effects that of this setting: can bumper and absorbing shock section 5 along himself axial movement, when wheel 2 clashes into
During to horizontal barrier, can avoid or reduce the amplitude of toy car transverse vibration.For embodiment two, optimization, for
Strengthening the damping effect that dolly is horizontal, the material of fixture block 8 is also chosen by Elastic plastic-rubber and makes or stay between fixture block 8 and draw-in groove 9
Deposit suitable buffer distance.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
