Description
Technical field
The utility model relates to automobile combination meter bonnet technical field, is specifically a kind of combination instrument rear cover structure device.
Background technology
Along with the development of injection moulding and forming technique, the application of plastics is also more and more wider, and the vital parts bonnet in automobile combination meter is also Plastic Parts.It is mainly used for protecting PCB parts, and can prevent dust from entering.
Current rear cover structure is designed with two kinds, and one adopts thread-forming screw, bonnet, PCB, lamp-box frame is fixed together, this structure mature and reliable, but cost is higher, installs inconvenient.Another adopts buckle structure, and be connected to by bonnet on lamp-box frame, clip between simultaneously by PCB, this infrastructure cost is lower, but due to Plastic Parts yielding, cause buckle scale error comparatively large, cause and difficulty is installed and buckle lost efficacy.
The design relation of bonnet is to the cost of combination instrument and protection, protection against dust, and in the market competition of fierceness, cost factor has become more and more important.Based on above situation, in the urgent need to providing a kind of novel combination instrument rear cover structure device.
In order to solve the problem, this case is life therefrom.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of with low cost, easy for installation, combination instrument rear cover structure device that clamping is firm.
To achieve these goals, the technical solution of the utility model is as follows: a kind of combination instrument rear cover structure device, comprise lamp-box frame, pcb board and bonnet, described bonnet is made up of the sheet type PP sheet material of 0.25 ~ 0.35mm thickness, lamp-box frame is provided with some buckles and registration mast, pcb board offers the hole passed for registration mast, the side of bonnet offers some draw-in grooves matched with buckle, the end face of bonnet is provided with some knock holees matched with registration mast.
As preferably, the thickness of described bonnet is 0.3mm.
As preferably, described registration mast and knock hole are interference fit.
As improvement, position corresponding with components and parts on described bonnet offers the hole of the first device empty avoiding of some confessions.
After adopting technique scheme, the utility model compared with prior art, has the following advantages: the utility model combination instrument rear cover structure device, and bonnet adopts sheet type PP sheet material to make, and whole bonnet is not only thin but also light, with low cost; Patching to coordinate and fix lamp-box frame, pcb board and bonnet three and replace traditional thread-forming screw fixed form by registration mast and knock hole, structure is simple, easy for installation; Meanwhile, coordinate the snap-fit engagement with buckle and draw-in groove, guarantee that lamp-box frame, pcb board and bonnet three clamping are firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of bonnet in the utility model combination instrument rear cover structure device.
Fig. 2 is the structural representation after the utility model combination instrument rear cover structure device has assembled.
Fig. 3 is the structural representation of the utility model combination instrument rear cover structure device lamp-box frame, pcb board and bonnet three snap-fit engagement.
Shown in figure: 1, lamp-box frame 2, pcb board 3, bonnet 4, buckle 5, registration mast 6, hole 7, draw-in groove 8, knock hole.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1 to Figure 3: a kind of combination instrument bonnet 3 constructional device, comprises lamp-box frame 1, pcb board 2 and bonnet 3.It is more than prior art, primary object of the present utility model is: bonnet 3 is made up of the sheet type PP sheet material of 0.25 ~ 0.35mm thickness, lamp-box frame 1 is provided with some buckles 4 and registration mast 5, pcb board 2 offers the hole (not marking in figure) passed for registration mast 5, the side of bonnet 3 offers some draw-in grooves 7 matched with buckle 4, the end face of bonnet 3 is provided with some knock holees 8 matched with registration mast 5.
The thickness of bonnet 3 is 0.3mm.The Thickness Design of bonnet 3 is become 0.3mm, under the prerequisite ensureing bonnet 3 intensity, sheet material can be saved to greatest extent, thus reduce costs further.Certainly, the utility model does not do concrete restriction to the thickness of bonnet 3, and in other embodiment, the thickness of bonnet 3 can be the arbitrary value between 0.25 ~ 0.35mm.
Registration mast 5 and knock hole 8 are interference fit.So, can guarantee that knock hole 8 is stuck on registration mast 5 firmly, thus guarantee fixation between lamp-box frame 1, pcb board 2 and bonnet 3 three.
In addition, on bonnet 3, the position corresponding with components and parts offers the hole 6 of the first device empty avoiding of some confessions.So guarantee dust-proof effect, the shape of hole 6, size and components and parts match.
During installation, first pcb board 2 is shelved on lamp-box frame 1, and guarantee that registration mast 5 is through the hole on pcb board 2, then the knock hole 8 on bonnet 3 is aimed at the registration mast 5 on lamp-box frame 1, and along registration mast 5, bonnet 3 is fastened on pcb board 2 with special tool, finally the draw-in groove 7 on bonnet 3 side is connected on the corresponding buckle 4 of lamp-box frame 1, so far, installs.
The utility model combination instrument bonnet 3 constructional device, bonnet 3 adopts sheet type PP sheet material to make, and whole bonnet 3 is not only thin but also light, with low cost; Patching to coordinate and fix lamp-box frame 1, pcb board 2 and bonnet 3 three and replace traditional thread-forming screw fixed form by registration mast 5 and knock hole 8, structure is simple, easy for installation; Meanwhile, coordinate with the snap-fit engagement of buckle 4 with draw-in groove 7, guarantee that lamp-box frame 1, pcb board 2 and bonnet 3 three clamping are firm.
Upper described foundation embodiment is enlightenment, and by above-mentioned description, relevant staff in the scope not departing from this utility model thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its scope protected according to right.
