The specific embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with specific embodiment, technical scheme of the present invention is further introduced.
As shown in Figure 2 and Figure 9, the running part on automotive spare tire hoist provided by the invention top and the structure of existing spare tyre lifter are basic identical, comprise driving wheel 3 and flower wheel (not shown), driving chain 4 is connected in the draw-in groove of described flower wheel, by eccentric shaft (not shown), described driving wheel 3 and flower wheel are fixed on support housing 1, the both sides of described support housing 1 are fixed with crossbeam 2, rocking bar 5 is connected with described eccentric shaft, for handling the motion of described spare tyre lifter; In order to meet the spare tyre of same car different model, fix, the embodiment of the present invention is improved the fixed part of described automotive spare tire hoist bottom, be provided with and place the pallet 8 of spare tyre and be placed on the spacing ring 6 on described pallet 8, a side of described pallet 8 is provided with for connecting the hook 10 of described driving chain 4; Described spacing ring 6 comprise interconnect, unequal the first annulus 61 of diameter and the second annulus 62, and the wheel rim centre hole free-running fit of described the first annulus 61 and the first spare tyre a to be installed, the wheel rim centre hole free-running fit of described the second annulus 62 and the second spare tyre b to be installed.
As shown in Figure 3-Figure 5, when standby wheel is installed, first described pallet 8 is placed on spare tyre lifter under on ground, described the first spare tyre a is placed on described pallet 8, the convex surface of wheel rim upward, then described the first annulus 61 is placed in the wheel rim centre hole of described the first spare tyre a, again described the second spare tyre b is enclosed within on described the second annulus 62, wheel rim convex surface down, finally described driving chain 4 is hung on described hook 10, rotating rocker 5, buttress spare tyre, make spare tyre level increase, arrive after end of travel, utilize bearing pin that spare tyre lifter is fixed on car load.In uphill process, notice that chain naturally droops, after spare tyre contact vehicle body crossbeam, rotate again approximately one circle, rely on the pressure locking between spare tyre tyre surface and vehicle body crossbeam spacing, prevent rocking of spare tyre.
This automotive spare tire hoist adopts pallet to add the design of spacing ring, and the spare tyre of different model can be installed simultaneously, guarantees that two spare tyres can not move or relative motion, fixed, and spare tyre lifter is simple in structure, is easy to realize.
For convenient, install, described the first annulus 61 and described the second annulus 62 be the donut of arranging up and down, after described the first spare tyre a and described the second spare tyre b are installed, can guarantee good right alignment, avoid rocking waiting and fix illusive phenomenon generation.
Understandably, described the first annulus 61 and described the second annulus 62 can be also the donut structure of inside and outside layout.
Or, described the first annulus 61 and described the second annulus 62 are not concentric ring structure yet, during use, two annulus are all placed on described pallet 8, and connect with a connecting panel, described connecting panel is provided with the through hole that described hook 10 passes through, and this structure also can complete the lifting of different model spare tyre and fix.
In the present embodiment specific implementation process, between the wheel rim of the wheel rim of described the first spare tyre a and described the second spare tyre b, also can place rubber pad 7, be illustrated in figure 6 the structural representation of described rubber pad 7, and described rubber pad 7 is identical with the rim contour of spare tyre that is positioned at below, thereby can reduce vibration, and can prevent that described rubber pad 7 from scurrying out from wheel rim.
In another preferred embodiment, the junction of described the first annulus 61 and described the second annulus 63 is provided with stay bearing plate 63, and described stay bearing plate 63 is at least two groups, and when stay bearing plate 63 is only set described in two groups, described in two groups, stay bearing plate 63 is arranged on the two ends of the same diameter of the annulus that in described spacing ring 6, diameter is larger, as shown in Figure 7.When a spare tyre is only installed, described stay bearing plate 63 can play to spare tyre to be installed the effect of support, while guaranteeing that described spacing ring 6 is placed on described pallet 8, above the annulus coordinating with spare tyre to be installed is positioned at, so that after spare tyre rises, its tyre surface can with vehicle body crossbeam force fit, and rely on pressure locking between the two spacing.So, described automotive spare tire hoist just can be easily for the installation of the spare tyre of one or two different model.
Further, the annulus that in described spacing ring 6, diameter is larger can be provided with breach at described stay bearing plate 63 places, and described stay bearing plate 63 is arranged on to the inward flange that described the first annulus 61 is connected with described the second annulus 2, reliable to guarantee described stay bearing plate 63 intensity.
As shown in Figure 8, a side relative with described hook 10 is set on described pallet 8 also can arrange base 9, the height of described base 9 is more than or equal to the wheel rim centre hole of the spare tyre that is positioned at below apart from the height on ground, make described hook 10 highly exceed wheel rim centre hole, with the close together of described driving chain 4, convenient connection.
Between described pallet 8 and described hook 10, also can be provided with boss 81, weld with described pallet 8 and described hook 10 respectively at the two ends of described boss 81, described boss 81 both can further increase the height of described hook 10, also can strengthen the intensity of described hook 10 and described pallet 8 junctions.
Further, described boss 81 can be cylinder boss, and with described spacing ring 6 be positioned at below ring gap coordinate, thereby spacing ring 6 is played to certain position-limiting action, further prevent rocking of spare tyre.
As shown in Figure 9, on the basis of the above-mentioned technical solutions of this embodiment, described automotive spare tire hoist also comprises pull back spring 11, one end of described pull back spring 11 is connected with described driving wheel 3, the other end is connected with a side of described driving wheel 3 laminatings with described support housing 1, makes the lifting process of spare tyre more steadily smooth.
As shown in figure 10, described automotive spare tire hoist also comprises spare tyre lifter lock 12, particularly, at the end face of described rocking bar 5 along rocker shaft to inwardly having blind hole, the inwall of described blind hole has cannelure, the lock core of described spare tyre lifter lock 12 coordinates and locks with described groove, prevents that spare tyre lifter is stolen.
Embodiment shown in above foundation is graphic describes structure of the present invention, feature and action effect in detail; the foregoing is only preferred embodiment of the present invention; but the present invention does not limit practical range with shown in drawing; every change of doing according to conception of the present invention; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet specification sheets and illustrating contain spiritual, all should be in protection scope of the present invention.
