Description
Technical field
The present invention relates to vehicular spare parts field, especially, relate to a kind of bearing circle indicating device.
Background technology
Be 201320820240.7 at application number, patent name is in the patent application of spiral wall type bearing circle indicating device, propose a kind of structure of direction indication disc spins angle state, roughly as shown in Figure 1, namely in a circular base shell 1, one continuous print spiral wall 2 is arranged, this spiral wall 2 from close to base shell 1 circle centre position to external irradiation, end terminates in the circular side wall 11 of base shell 1; Be limited in by a ball 3 in helical duct 20 that this spiral wall 2 formed, like this, no matter bearing circle turns over how many angles, and ball 3 all under gravity, remains on vertical direction by Free-rolling.If, ball 3 is shown in Fig. 1 during position, base shell 1 turns over one week with bearing circle cw, then ball 3 is by under the constraint of Action of Gravity Field and spiral wall 2, sinks down into the position of below one deck of helical duct 20, that is position b; On the contrary, when base shell 1 turns over one week with bearing circle conter clockwise, then ball 3 will rise to position c; As can be seen here, this spiral wall type bearing circle indicating device in theory completely can the direction indication dish angle condition that turns over.
But, in actual manufacture and process on probation, but found some very typical practical problemss.First, for the indicating device shown in Fig. 1, ball 3 can only in the radius straight down that indicating device presents to the circular arc interface of user lifting moving, therefore the attention of user is only confined on this radius straight down; Because the space that bearing circle can be arranged indicating device is very limited, therefore the radius of described base shell is also very limited, and will judge the distance of ball lifting moving on this very limited radius, its degree of difficulty is very high; When bearing circle turns over half-turn, ball is only elevated a small distance, is difficult to distinguish under light state, and when bearing circle turns over 1/4th circles, is difficult to especially distinguish.
In view of this kind of situation, application number is it is also proposed a kind of affiliate program in the patent application of 201320820240.7, that is, at the front capping one piece transparent panel 4 as shown in Figure 2 of described base shell 1; On this panel 4, make a marked circle 40, the position of this marked circle corresponds to steering wheel return timing, and ball 3 place is position; Described panel 4 is labeled circle and is divided into two parts 41,42, and these two parts two kinds of different color dyes, like this, when ball 3 is in regions of different colours, turn over different clockwises corresponding to bearing circle.For this kind of scheme, clearly indicate the position residing for steering wheel return timing ball 3, but, as turn over for further direction indication dish other arbitrarily angled time, mark corresponding to ball, just must continue to make marked circle on panel 4, N number of angle position be indicated, just need to make N number of concentric marked circle; Like this, after a large amount of concentric marked circle and the spiral wall of indicating device inside visually overlap, will the display effect of whole indicating device be made to become in disorder, nobody be ready to use at all; Further, even if not in disorder, same, for this tagging scheme, still make the attention of user only be confined to the moving state of ball 3 on radius straight down, observe difficulty still very greatly, cause unmanned gladly use.
In addition, be the patent application of 201320820240.7 for application number, the problem that also existence one is difficult.Its difficulty is: need between ball 3 and helical duct 20 to keep a kind of very delicate friction effect.
When friction force between ball 3 and helical duct 20 is larger, ball 3 is very likely under friction force traction, and transfer, in indicating device, cause indicating device to turn over a circle, and ball 3 keeps original position in helical duct; To this situation, wish that the friction force of helical duct 20 is the smaller the better.
But, radius of curvature due to spiral wall 2 is continually varying, therefore, in the process that ball 3 is close to the indicating device center of circle, that is in the direction moving process that radius of curvature reduces gradually, spiral wall 2 is by the elastic deformation of self, by the thrust of giving 3 one, ball between tangential and radial direction, under the effect of this thrust, the moment that bearing circle suspends, a circle is flown in the direction that ball 3 very likely increases gradually to radius of curvature, causes misdirection; Jolting, urgency on road surface beats bearing circle, and e.g., when bearing circle is suddenly beaten in the parking stall being covered with ornamental slab for paving the floor, this kind of phenomenon is extremely obvious; For this situation, wish that again the friction force of helical duct 20 is comparatively large, with the thrust be made up of the elastic deformation of spiral wall 2 of contending with.
For this problem, relate to the gap size between helical duct and ball, the roughness of helical duct, the roughness of ball, that is the radius of curvature of spiral wall is with many-sided factor such as rate of change of angle, this many-sided composite factor is needed to keep delicate balance, consider from the angle of machining accuracy, there is great difficulty, almost cannot solve.
For two subject matters existing for above-mentioned patent application, below will propose solution, applicant with comparatively simple technological means, will overcome an above-mentioned difficult problem; It should be noted that, at this, petition for examination person, with rich experience and wide visual field, conceives solution in advance, obtains following solution to understand the need of paying creative work, and simply and directly vetos the creativeness of the application with scheme by mistake.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 3, this mechanical type bearing circle indicating device comprises the transparent panel (can be one block of clear glass or resin disk, not shown) of base shell 1 described in the base shell 1 of a lid and a capping; In the oblate cylindrical cavity of described base shell 1 inside, be shaped with one continuous print spiral wall 2; Two side planes of described spiral wall 2 are sandwiched by the bottom surface of described cavity and described panel.
The spiral path of described spiral wall 2 is with the center shaft of described cavity for rotary shaft, and outmost turns end ends at the sidewall 11 of described cavity.
In the helical duct 20 formed between the bottom surface of described cavity, described spiral wall 2, described panel, Feng Youyi the ball 3 that can roll in helical duct 20; On the bottom surface of described cavity, along the path of described helical duct 20, form a helix scale, the place-centric when initial point of this scale is in steering wheel return positive status residing for described ball 3, that is the position at roller 3 place in Fig. 1.
With described initial point for starting point, along helical duct 20 clockwise direction, often turn over N angle, mark the mark of an instruction angle, until mark the extreme angles that can turn in the counterclockwise direction to bearing circle; And with described initial point for starting point, along helical duct anticlockwise direction, often turn over N angle, mark the mark of an instruction angle, until mark the extreme angles that can turn over along clockwise direction to bearing circle.For this reason, the number of turns that rotates of described helical duct 20, only need to ensure in this helical duct 20 can mark extreme angles described in two by aforementioned claim; In the case, the number of turns of helical duct 20 is too much unsuitable, in order to avoid increase the redundant area of whole indicating device; Generally, from returning positive position, bearing circle all can only turn over 1.5 weeks to cw or conter clockwise, and therefore, described helical duct 20, from described origin position, rotates 1.5 weeks to external irradiation, and the radiation that inwardly rotates was slightly larger than 1.5 weeks; Here, inwardly rotate slightly larger than 1.5 weeks, mainly in order to the end of the most inner lane making spiral wall 2 is formed hook-shaped, just catch on the ball 3 being in end position.
In Fig. 3 embodiment, the mark of described instruction angle, often turns over 90 scale notes once, and in units of the number of turns, with realistic demand; As shown in Figure 3, be demarcation line with initial point, the mark opposite number each other that the mark of the instruction angle on clockwise direction is corresponding with on anticlockwise direction.
Further, on described helix scale, be demarcation line with initial point, the scale color on clockwise direction is different from the scale color on anticlockwise direction; As, clockwise direction can make redness, anticlockwise direction can make green.
Above-mentioned mechanical type bearing circle indicating device, bearing circle forwards to the process of end position from returning positive position cw, and the initial point from described helix scale is rolled to the conter clockwise maximum value of scale by ball 3, is namely rolled to the position of 1.5 shown in Fig. 3; And when bearing circle is inverted to end position, ball 3 can be rolled to again the cw maximum value of helix scale, i.e. the position of-1.5 in Fig. 3; Like this, make the tolerance for ball 3 shift position, from the very short distance vertical direction, be extended to the very long distance on helix line; Thus the angle making indicating device turn over can carry out marking more closely-spacedly; And make the visual attention of user no longer be confined on the radius straight down of panel, then stake is on the helix scale on whole helical duct; When ball is in certain semiaxis of scale, namely knows that bearing circle is in certain clockwise, and turned over N degree; When ball is in another semiaxis of scale, namely knows that bearing circle is in another clockwise, and turned over M degree; This makes the acquisition of the ease of user's reading angular data improve hugely, significantly improves the life practicality of indicating device; And, in the case, the panel that indicating device presents very neat and tidy again, helix scale is full of whole helical duct, make the attention of user be full of whole panel, comparatively speaking, the visual symmetry that indicating device is presented obtains expansion more than one times, the visual effect brought of technical characteristic, improves the acceptable degree of user extremely effectively thus.
In addition, preferably, described ball 3 can adopt steel ball, and described helical duct 20 inner sealing has water body.Because ball surfaces is extremely smooth, therefore, between the spiral wall of steel ball and helical duct upper and lower sides, there is minimum friction force, this ensured steel ball can not because being subject to the traction of friction force that spiral wall surface produces transfer in indicating device; And when the elastic deformation of spiral wall produces thrust to steel ball, because the drag size of water body and steel ball are in the positive correlation of water body medium velocity, therefore, steel ball can only be pushed with less speed, causes the direction that cannot increase gradually to helical duct radius of curvature to leap rapidly a circle; Based on this principle, together constituted the comprehensive friction force of helical duct described in background technology by water body resistance, spiral wall friction force; Through test, this comprehensive friction force can reach the delicate friction effect described in background technology just, makes bearing circle under different road conditions and different rotating speeds, and indicating device all can carry out work like clockwork.
And if steel ball abandoned by described ball 3, then mercury liquid can be adopted to form; In the case, the size of described helical duct 20, the processing request of roughness aspect reduce with obtaining essence, and the cost of described base shell 1 is declined to a great extent.Because mercury droplet relies on self huge tension force, full ball-type can be condensed in its natural state, and can not cave in as water droplet, therefore, after mercury droplet is injected into described helical duct 20, its appearance presented is extremely similar in appearance to spherical ball; But, it is compared with steel ball, has possessed multiple advantage: the geomery of one, mercury droplet can be adapted to the width of helical duct 20 automatically, when disposable instillation amount of mercury is less, it will present spheroidal, and inject amount of mercury larger time, its by restrained in elliposoidal, in any case, because mercury has the ability with thing figuration, therefore, it when moving along helical duct, and does not almost have friction force between spiral wall; And when the elastic deformation that mercury droplet bears spiral wall is impacted, because mercury has good inner elastomeric, this kind of damping of shocks can be disintegrated completely, thus avoid the outside one deck flying to helical duct; Two, the density of mercury is apparently higher than iron and steel, and therefore, its effect by gravity is more obvious, makes it more stably to remain on vertical direction.
In addition, it should be noted that, for the second technical scheme in summary of the invention, only Fig. 3 need be revolved turnback and form a newly figure, then in new figure, the position at ball 3 place is under steering wheel return positive status, the position residing for bubble; Due to the program and the first scheme extremely symmetrical, therefore, after detailing the first technical scheme, namely there is no need again to the second technical scheme mapping has repeated.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
