Problems solved by technology

Automotive sensors generally use silica gel to bond the sensor back cover and the housing. The back cover and the housing are directly bonded on a plane, and the back cover is prone to warping. After the silicone between the back cover and the housing is cured, there are overflows and holes. , lack of glue and other defects, and even the back cover falls off after the product has been used for a period of time

Embodiment Construction

[0018] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0019] Such as figure 1 and figure 2 As shown, a sensor back cover and housing assembly structure, including the sensor back cover and the housing, is provided with a raised back cover wall 5 on the edge of the back cover assembly surface, and the assembly surface of the housing is a groove structure. A positioning protrusion 2 is arranged in the groove structure of the housing, and the inner surface of the back cover wall 5 is adapted to the outer surface of the positioning protrusion 2, and the positioning protrusion of the housing and the convex wall of the housing edge are used for filling Glue the grooves3.

[0020] Wherein, the inner side of the back cover wall 5 is provided with a clamping strip 4, and the positioning protrusion 2 is provided with a clamping groove 1 matching with the...

Abstract

The invention discloses a sensor rear cover-housing assembling structure and an assembling method thereof. The sensor rear cover-housing assembling structure comprises a sensor rear cover and a housing. An edge of the sensor rear cover is provided with a raised rear cover arm. The housing is provided with a positioning raised part fitting to a wall of the sensor rear cover. A groove for glue filling is arranged between the positioning raised part and a raised wall of a housing edge. The sensor rear cover gets stuck on the housing and does not move freely so that rear cover fixing position stability consistency is good; an after-glue filling technology is used so that glue is arranged only between an outer wall of the groove of the housing and an outer side of a wall of the sensor rear cover and the bottom of the wall of the sensor rear cover is not coated with glue and thus in glue curing, rear cover cocking is avoided; a sectional type vacuum-pumping technology is adopted so that air in glue is discharged completely and glue splashing and overflow are reduced in glue pumping and appearance consistency of a cured glue product is good; and a vacuum-pumping process is carried out before curing so that air in glue is discharged completely and adhesion of the glue to the housing and the sensor rear cover is improved.

Description

technical field [0001] The invention relates to the technical field of automobile sensors, in particular to an assembly structure and assembly method of a sensor back cover and a housing. Background technique [0002] Automotive sensors are generally small in size and used in harsh environments, and the assembly requirements for the rear cover of the sensor are relatively strict. Automotive sensors generally use silica gel to bond the sensor back cover and the housing. The back cover and the housing are directly bonded on a plane, and the back cover is prone to warping. After the silicone between the back cover and the housing is cured, there are overflows and holes. , lack of glue and other defects, and even the back cover falls off after the product has been used for a period of time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an assembly structure between the sensor back cover and the housing, so as to a...
