The top of butt fusion muscle 210 imbeds and welds in the face of weld and makes preceding shell 200 and face guard 100 fixed connection under ultrasonic bonding's effect, and the butt fusion is firm, simple structure, and the machine-shaping of being convenient for once only drops into lowly, connects the mode of preventing the pad is pasted to abnormal sound for traditional buckle, has reduced production processes, has reduced manufacturing cost, has prolonged life simultaneously.
Further, referring to fig. 3, the cross-sectional shape of the welding rib 210 is triangular.
The triangular cross-sectional shape makes the welding rib 210 have stability after being embedded and welded on the welding surface under the effect of ultrasonic welding, and the welding between the front shell 200 and the face guard 100 is firm, and is difficult to produce deformation and generate abnormal sound.
In an alternative to this embodiment, it is preferable that,
a positioning structure is further disposed between the mask 100 and the front case 200, and the positioning structure is used for positioning the mask 100 and the front case 200.
Specifically, referring to fig. 2 and 3, the positioning structure includes a positioning rib 110 disposed on the bottom surface of the mask 100 and a positioning groove 220 disposed in the groove of the front shell 200, and the positioning rib 110 is inserted into the positioning groove 220 to position the mask 100 and the front shell 200.
The structure of the positioning rib 110 arranged on the face mask 100 is matched with the structure of the positioning groove 220 arranged on the front shell 200, so that the face mask 100 and the front shell 200 are positioned accurately, and dislocation is not generated before welding.
Preferably, the positioning ribs 110 arranged on the mask 100 are five in total and are uniformly distributed on the peripheral edge of the mask 100; correspondingly, the number of the positioning grooves 220 formed on the front case 200 is five, and the positioning grooves are uniformly distributed in the groove of the front case 200.
Further, referring to fig. 3, the positioning rib 110 perpendicularly intersects the welding rib 210.
In an alternative to this embodiment, it is preferable that,
the mask 100 is made of PMMA material.
The PMMA material has high transparency, the light transmittance can reach 92%, the surface hardness is high after hardening, the PMMA material has good fatigue strength, environmental resistance and organic solvent resistance, and the PMMA material can be widely applied to various use scenes.
In an alternative to this embodiment, it is preferable that,
the front case 200 is made of a PC and ABS composite material.
The front shell 200 is made of a composite material of PC and ABS, integrates the functional characteristics of PC and ABS, has the advantages of easy processing and good thermal stability, increases the heat-resistant dimensional stability of ABS, improves the low-temperature property of PC and has good forming effect.
It should be further noted that the welding rib 210 on the front shell 200 is disposed in the groove to effectively prevent the plastic from overflowing during the welding process, and the plastic is accumulated in the groove to make the welding more firm.
Example two
The embodiment of the utility model provides an automobile, including the on-vehicle instrument housing mentioned in embodiment one.
