Description
Technical field：
The present invention relates to physical field more particularly to automobile instrument, especially a kind of concave needle body automobile meter pointer.
Background technique:
In automobile meter pointer design, in order to make narrow head pointer needle body whole guide-lighting uniform, needs to be arranged on needle shaft seat and lead
Body of light, light guide are the stereochemical structure of one fixed width and height, in the prior art, in order to consider practical set, before pointer cap
The narrow header structure at end limits the height and width of light guide on needle shaft seat, reduces needle body incidence surface, reduces the biography of light
Efficiency is led, since light guide is unable to reach certain high width requirement, causes gauge pointer backlight illumination and uniformity poor, simultaneously
The incidence surface of needle body can also be blocked by pointer cap, occur further increasing the damage of effective luminous energy without incidence surface under extreme case
Consumption, reduces the backlight effect of pointer.
Summary of the invention：
The purpose of the present invention is to provide a kind of concave needle body automobile meter pointer, this automobile meter pointer passes through
Groove is set on needle body bottom cover, with meet light guide to height and width space requirement, solve in the prior art due to
The narrow header structure of pointer cap makes the light guide on needle shaft seat be unable to reach certain high width, causes needle body incidence surface small, light conduction
Low efficiency, the problem of backlight effect difference.
This concave needle body automobile meter pointer of the invention, including pointer cap, balance weight, needle body, needle pivot, needle shaft seat
And light emitting diode, the needle body tail end be equipped with needle body bottom cover, the pointer cap cover on the needle body bottom cover and needle shaft seat with
The needle shaft seat riveting, the balance weight are set in the mounting groove of needle shaft seat lower surface tail portion and rivet with the needle shaft seat,
The needle pivot is vertically set on needle shaft seat lower surface, and the light emitting diode is arranged below the needle pivot, described
Needle shaft seat, needle pivot, needle body and needle body bottom cover are all made of translucent material, wherein are equipped among the bottom of the needle body bottom cover recessed
Slot, the slot opening are arranged down along needle body axial direction, and the groove location is corresponded on the needle shaft seat equipped with inclined-plane phase
To the first right-angled trapezium light guide and the second right-angled trapezium light guide of setting, the first right-angled trapezium light guide and the second right angle ladder
The width of shape light guide is respectively less than the recess width, the first right-angled trapezium light guide and the second right-angled trapezium light guide
Top is higher by needle shaft seat upper surface and is located in the groove.
Further, the inclined-plane on the first right-angled trapezium light guide and the second right-angled trapezium light guide is in 45 degree of angles
Reflective inclined-plane.
Further, the pointer cap is made of black light-proof material.
Further, the needle shaft seat and the needle pivot are integrally formed, the needle body and needle body bottom cover one at
Type.
Further, thermoprint is printed on the bottom portion of groove groove face, the needle body upper surface and the needle body lower surface
Film.
The working principle of the invention is：After the light emitting diode of gauge pointer bottom is lighted, light is by needle pivot along straight
Line conducts upwards, when reflective oblique on light conduction to needle shaft seat the first right-angled trapezium light guide and the second right-angled trapezium light guide
When on face, reflective inclined-plane by refraction and reflect by light toward two side directions conduction enter needle body, another part light continue to
Bottom portion of groove groove face is travelled over to, and needle body is reflected by the blocking film on groove face, completes to shine the backlight of entire needle body
It is bright.
The present invention compares with prior art, and effect is positive and apparent.The present invention passes through the needle with groove structure
Body design, increases the height and width of needle shaft seat light guide, improves optical energy utilization efficiency, while the needle body increased enters light
Face keeps light conduction high-efficient, and backlighting effect is good.
Detailed description of the invention：
Fig. 1 is configuration schematic diagram of the invention.
Fig. 2 is needle structure schematic diagram of the invention.
Fig. 3 is needle shaft holder structure schematic diagram of the invention.
Fig. 4 is the schematic diagram of the section structure of the invention.
