Embodiment
Below will combine accompanying drawing and embodiment that the present invention is explained in further detail for the ease of it will be appreciated by those skilled in the art that.
Shown in accompanying drawing 1～5, a kind of instrument comprises driving mechanism 1, pcb board 2, support backlight 3, index dial 4 and the pointer 5 be located at successively in the instrument housing; Driving mechanism 1 is fixed on the pcb board 2; On index dial 4, be provided with numerical value and indication alert icon, numerical value such as the speed of a motor vehicle, rotating speed, fuel oil or water temperature for example, indication such as long-and-short distant light, securing band or braking alert icon; Index dial 4 is installed on the support 3 backlight, and numerical value is provided with light hole with indication alert icon corresponding position on support 3 backlight; LED lamp 6 is installed on pcb board 2, and LED lamp 6 light pass light hole and shine on the index dial 4, thereby for index dial 4 back light are provided; Index dial 4 is passed in the bottom of pointer 5, support backlight 3 is connected with driving mechanism 1.
Wherein, Be provided with the dish 7 that is in the light at support 3 inner bottom parts backlight, this dish that is in the light 7 can adopt the light transmissive material polymethylmethacrylate to process, and the dish 7 that is in the light is provided with high photic zone 71 and low light transmission district 72; High photic zone 71 is positioned at the below of pointer 5, and 72 surfaces, low light transmission district can be handled through frosted and realized; This dish 7 that is in the light also is connected with driving mechanism 1, and driving mechanism 1 drives dish 7 rotation synchronously in the same way of being in the light when driving pointer 5 rotations.Driving mechanism 1 drives pointer 5 and rotates; Pointer 5 certain reading of indication; Simultaneously, driving mechanism 1 also drives the dish 7 that is in the light and and then rotates synchronously, because high photic zone 71 is positioned at the below of pointer 5 all the time; The light of LED lamp 6 emissions arrives index dial 4 through the high photic zone on the dish 7 that is in the light 71, makes near the high bright demonstration pointer 5 indication reading zones on the index dial 4; The light of LED lamp 6 emissions arrives index dial 4 through the low light transmission district on the dish 7 that is in the light 72, makes to show slinkingly outside the pointer 5 indication reading zones on the index dial 4 to show; The driver sees that the left and right sides, pointer 5 indication readings zone backlight illumination is regional high than other like this, causes driver's attention easily, makes things convenient for the instantaneous information that reads on the index dial of driver, for the driver safety operation provides guarantee.Dish 7 rotates with pointer 5 all the time in the same way synchronously owing to be in the light, and when pointer 5 pointed to certain reading on the index dial 4 like this, near the zone this reading was with regard to high bright demonstration, and pointer 5 not stalls are moving, and the highlight regions on the index dial 4 is also being followed dynamic transfer.
In order to make pointer 5 indication reading regional luminances the highest, high photic zone 71 horizontal center lines overlap with pointer 5 horizontal center lines, and when pointer 5 was in original state and promptly indicates 0 scale, the center line of dish 7 highlight regions that are in the light overlapped with pointer 5 and 0 scale mark; When driving mechanism 1 drives pointer 5 rotations and drives the dish 7 that is in the light and rotate synchronously in the same way; When pointer 5 points to certain reading on the index dial 4; The center line of dish 7 highlight regions that are in the light overlaps with pointer 5 and this scale mark, and this scale mark regional luminance is the brightest, causes driver's attention easily; Make things convenient for the instantaneous information that reads on the index dial of driver, for the driver safety operation provides guarantee.
In the present embodiment; Driving mechanism 1 is the dual-axle motor of axle 11 in having and outer shaft 12; In axle 11 can independent operation with outer shaft 12, axle 11 interference are installed and are cooperated in pointer 5 and the motor, are in the light to coil 7 and cooperate with motor outer shaft 12 interference installation; The reading that axle 11 drives on the pointer 5 indicating graduation dishes 4 in the motor, motor outer shaft 12 drive the dish 7 that is in the light and rotate.Distinguish independent operation owing to dual-axle motor drives interior axle 11 in the same way synchronously with outer shaft 12, realize the brightest demonstration of pointer 5 indication index dials, 4 regional luminances of its top through 71 rotations of the high photic zone on the dish 7 that is in the light.
Structural design of the present invention is unique, novel, and cost is low, through be provided with at support 3 inner bottom parts backlight one be connected with driving mechanism 1 be in the light and coil 7; Driving mechanism 1 drives dish 7 rotation synchronously in the same way of being in the light when driving pointer 5 rotations, guaranteed that pointer 5 indication reading near zones are positioned at high photic zone 71 all the time, when gauge pointer 5 is indicated to certain reading on the index dial 4; This reading can high bright giving prominence to show; The driver sees that this left and right sides, reading zone backlight illumination is regional high than other like this, and is high more the closer to pointer brightness, causes driver's attention easily; Make things convenient for the instantaneous information that reads on the index dial of driver, for the driver safety operation provides guarantee.
The foregoing description is merely preferred implementation of the present invention, and in addition, the present invention can also have other implementations; For example do not use pointer 5; The high photic zone 71 of dependence index dial 7 substitutes the function of pointer 5, indicates current meter information, and this structure can reach designing requirement of the present invention equally.That is to say that under the prerequisite that does not break away from inventive concept of the present invention, any conspicuous replacement all should fall within protection scope of the present invention.
