The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a novel LED meter display structure 10 according to the present application includes: a display window 11, a PCB board 12, and an instrument housing 13. The meter case 13 is rotatably connected with a rotation connection case 18, and the display window 11 is connected above the rotation connection case 18 to be rotatably connected to the meter case 13 through the rotation connection case 18. Thus, the speed can be adjusted by pressing the speed adjusting button when the display window 11 is rotated by pressing the display window 11.
As a specific structure, the meter housing 13, the rotating link housing 18, and the display window 11 together constitute an installation space into which the PCB 12 is installed. The PCB board 12 is connected to a lower side of the display window 11. A plurality of LED lamp beads 14 are provided on the PCB 12. The display window 11 is provided with a plurality of windows 112. The windows 112 correspond to the LED beads 14 one to one. The plurality of windows 112 are provided with a sealant 113 for sealing the windows 112, and the sealant 113 is potted in the windows 112 by potting. The production process is simple, the cost of the product is low, and the light of the LED lamp beads 14 inside can be seen through the window 112.
Foretell novel LED instrument shows structure 10 is through design window 112 on showing window 11 in order to carry out the printing opacity to LED lamp pearl 14 to it is sealed to glue filling in window 112, has reduced the cost of product like this, and has reduced the degree of difficulty of production technology and assembly, and the surface that can avoid the seal structure of window 112 department through glue filling is sealed in window 112 simultaneously receives the fish tail, guarantees the aesthetic property in the product use.
In a specific embodiment, the sealant 113 is an AB sealant composed of a combination of two kinds of glues. The composition of the sealant 113 includes: epoxy resin and curing agent.
Further, the sealant 113 includes an epoxy resin, a curing agent, and a diffusing agent. The AB glue is transparent, can see inside lamp pearl, influences the display effect of product, and shows under the highlight clear inadequately. And the added diffusant can ensure that the light transmission of the AB glue of the epoxy resin and the curing agent is more uniform, the whole body is black and gray, the display effect is improved, and the light indication can be clearly seen in the sun.
Specifically, the ratio of the epoxy resin, the curing agent, and the diffusing agent in the sealant 113 is 100:100: 10.
As a specific implementation mode, the display window 11 is made of ABS material and is formed by injection molding once, and is uniform in color and not easy to scratch.
As a specific embodiment, a frosted layer is disposed on the surface of the display window 11 to further improve the wear resistance of the surface layer of the display window 11.
As a specific embodiment, the PCB 12 is detachably coupled to the lower side of the display window 11 to facilitate the detachment or installation of the PCB 12. LED lamp pearl 14 demountable installation is in PCB board 12 to dismantle or install LED lamp pearl 14. Each LED lamp bead 14 is at least partially located in the window 112 corresponding thereto, which can ensure the effectiveness of the light transmission of the LED lamp beads 14.
In one embodiment, the plurality of windows 112 are arranged in a line parallel to the rotational axis of the knurled shaft. When the display window 11 is pressed, the light emitted from the windows 112 has a uniform change, and the visual effect is improved.
As a specific structure, two speed adjusting buttons are electrically connected below the PCB 12, and the speed adjusting buttons are below the PCB 12 and cannot be seen in the figure. The two ends of the display window 11 are respectively positioned above the two speed regulating buttons. The display window 11 is rotatably connected to the instrument housing 13 by means of a knurled shaft, i.e. the display window 11 is fixed to a rotary connection housing 18, and the rotary connection housing 18 is rotatably connected to the instrument housing 13 by means of a knurled shaft. Therefore, the speed regulating button is hidden below the display window 11, the whole appearance is atmosphere, the area of the button is large, the rocker structure is formed by the rotary connection of the knurling shafts, and the feedback of the hand feeling of the button is good.
Further, a sealed space 15 is formed below the display window 11, that is, the rotary connecting housing 18 and the display window 11 together form the sealed space 15. The sealed space 15 is sealed by a silicone gasket 16. The silicone gasket 16 is formed with two mounting grooves 161. The through column 17 is inserted into the mounting groove 161. Two speed regulating buttons are respectively inserted into through holes formed in the two through posts 17, and the end portions of the speed regulating buttons contact the bottoms of the mounting grooves 161. The waterproof structure of speed governing button department adopts the cartridge structure of straight-through post 17 plus silica gel circle pad, and assembly efficiency is high and the uniformity is good, guarantees that product batch waterproof performance is stable, very big reduction the assembly degree of difficulty, and manufacturing cost easily can descend. Simultaneously, can also give certain protection to the speed regulating button through straight-through post 17, avoid the speed regulating button to receive the impact.
Further, the groove bottom of the mounting groove 161 is formed with a stopper groove. The spacing groove is used for supplying straight-through post 17 to insert, and the one end of straight-through post 17 not only can install straight-through post 17 after inserting the spacing groove, can also compress tightly the silica gel circle pad of spacing tank bottom portion in order to guarantee the planarization of the tank bottom of mounting groove 161 through the one end of straight-through post 17. This ensures the effectiveness of pressing the throttle button.
In a specific embodiment, a locking groove 181 is formed above the rotation coupling housing 18, and a flange for engaging the locking groove 181 is formed at the lower side of the display window 11. The display window 11 is fixed to the upper side of the rotary connection housing 18 by the flange snap-in groove 181.
As a specific embodiment, the side surface of the meter case 13 is formed with a through hole. The through holes are used for electrically connecting the circuit to the PCB 12 so as to realize speed regulation control.
In a specific embodiment, the display window 11 has a curved surface structure. The design of the curved screen is obviously different from that of the traditional instrument, and the appearance diversification of the product is realized.
In a specific embodiment, the display window 11 has marks 111 formed at both ends of the upper surface thereof. The flag 111 is used to indicate whether to adjust the increase speed or to adjust the decrease speed. Two marks 111 are located directly above the two throttle buttons, respectively.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation modes fall within the protection scope of the present invention.
