Technical field
The utility model relates to mechanical field, particularly a kind of sensor.
Background technology
On home market, the elements such as chip, magnet, wire harness, mounting bracket are normally passed through once injection molded type by the manufacture for the sensor (such as speed pickup) of vehicle.But, the shape of chip do not considered by the existing sensor for vehicle in injection molding process, the bending angle of such as chip, thus the stream skewness of injection molding process chips both sides is weighed, and the Material shrinkage deformed region of the sensor of injection mo(u)lding is large, deformed region internal stress is large and drawdown deformation trend is obvious.
Utility model content
In order to solve the problem, the sensor that the utility model provides comprises injection-moulded housing and is positioned at the chip of described injection-moulded housing inside, and the shape of described injection-moulded housing is corresponding with the shape of described chip.
Compared with prior art, sensor of the present utility model at least has the following advantages: in sensor of the present utility model, the shape of the injection-moulded housing of sensor is corresponding with the shape of chip, the stream flow of chip both sides can be made in injection molding process balanced, and can make that the Material shrinkage deformed region of the product sensor of injection mo(u)lding reduces, deformed region internal stress reduces and the reduction of drawdown deformation trend.
Accompanying drawing explanation
Figure 1A-Fig. 1 F respectively illustrates stereographic map, front elevation, rear view, right view, the top and bottom perspective views of the sensor according to an embodiment of the present utility model.
Embodiment
Sensor according to embodiment of the present utility model is described with reference to the accompanying drawings.In the following description, many details have been set forth to make person of ordinary skill in the field more fully understand the utility model.But be apparent that for the technician in art, realization of the present utility model can not have some in these details.In addition, should be understood that, the utility model is not limited to introduced specific embodiment.On the contrary, can consider to implement the utility model by the combination in any of characteristic sum key element below, and no matter whether they relate to different embodiments.Therefore, aspect below, feature, embodiment and advantage use for illustrative purposes only and should not be counted as key element or the restriction of claim, unless clearly proposed in the claims.
Sensor (such as the speed pickup of vehicle) in state of the art at least has following shortcoming: the shape of chip do not considered by the sensor for vehicle of the prior art in injection molding process, such as do not consider the bending angle of chip, thus the stream skewness of injection molding process chips both sides is weighed, and the Material shrinkage deformed region of the sensor of injection mo(u)lding is large, deformed region internal stress is large and drawdown deformation trend is obvious.
Figure 1A-Fig. 1 F respectively illustrates stereographic map, front elevation, rear view, right view, the top and bottom perspective views of the sensor according to an embodiment of the present utility model.As shown in Figure 1A-Fig. 1 F, this sensor comprises outer field injection-moulded housing and is positioned at the sensing element (not shown) of injection-moulded housing inside, and sensing element such as comprises the element for realizing sensing function such as chip, magnet, wire harness.This sensor is formed by an injection moulding by means of mould.Wherein, the shape of the injection-moulded housing of sensor of the present utility model is corresponding with the shape of the chip of sensor, thus make the stream flow of chip both sides balanced, and can make that the Material shrinkage deformed region of the product sensor of injection mo(u)lding reduces, deformed region internal stress reduces and the reduction of drawdown deformation trend.
Continue as shown in Figure 1A-Fig. 1 F, the injection-moulded housing of sensor comprises groove structure, and this groove structure that injection-moulded housing is arranged may be used for alleviating the weight of injection-moulded housing and sensor.Concrete, this injection-moulded housing can comprise two or more groove structures, can obtain the identical groove structure of multiple shape by removing the material of same thickness on injection-moulded housing.Those of ordinary skill in the art can arrange the quantity of groove structure, size and position according to actual needs, and these modification do not depart from protection domain of the present utility model.Such as, as shown in Figure 1A-Fig. 1 F, injection-moulded housing can comprise two groove structures 11,12, to alleviate the weight of injection-moulded housing and sensor.
Continue as shown in Figure 1A-Fig. 1 F, the groove structure of the injection-moulded housing of sensor comprises the V-arrangement surface of the recess forming described groove structure, angle of inclination between two surfaces 21,22 on this V-arrangement surface is corresponding with the bending angle of described chip, thus make can to make the stream flow of chip both sides balanced in injection molding process, and can make that the Material shrinkage deformed region of the product sensor of injection mo(u)lding reduces, deformed region internal stress reduces, the reduction of drawdown deformation trend.In one preferred embodiment; angle of inclination between two surfaces forming this V-arrangement surface can be equal with the bending angle of chip; thus realize the technique effect of good stream equilibrium; but; it will be appreciated by those skilled in the art that; angle of inclination between two surfaces forming this V-arrangement surface can be similar to the bending angle of chip; such as can be bigger or be slightly less than the bending angle of chip and still can reach the technique effect of stream equilibrium, these modification do not depart from protection domain of the present utility model.In addition, as shown in Figure 1A-Fig. 1 F, the transition between two surfaces 21,22 forming this V-arrangement surface for seamlessly transitting, thus can reach good stream portfolio effect.
Continue as shown in Figure 1A-Fig. 1 F, the injection-moulded housing of sensor also comprises reinforcement, and this reinforcement can be arranged on injection-moulded housing along the axial direction of injection-moulded housing, thus plays the effect of the intensity improving sensor.In addition, the reinforcement on injection-moulded housing can also on other parts sensor being installed to vehicle time play guide effect, thus facilitate the installation of sensor.Those skilled in the art can arrange the quantity of reinforcement, size, shape and position according to actual needs, and do not depart from protection domain of the present utility model, preferably, can be provided with the reinforcement of multiple strip.Such as, as shown in Figure 1A-Fig. 1 F, the reinforcement 31 of 4 strips can be provided with, 32, 33 and 34, wherein, reinforcement 31 can be arranged on two groove structures 11 along the axial direction of injection-moulded housing, between 12, thus strengthening groove structure 11, the intensity at 12 places, reinforcement 32, 33 and 34 can be arranged on groove structure 11 along the axial direction of injection-moulded housing, other position of injection-moulded housing outside 12, preferably, reinforcement 31, 32, spaced apart with the even angle of 90 degree ground between 33 and 34, thus in a plurality of directions reinforcement is played to injection-moulded housing and guide effect is installed.
Sensor of the present utility model can be applied to multiple environment, and such as, sensor of the present utility model can be used as the speed pickup of vehicle.
In the technical solution of the utility model, because the shape of the injection-moulded housing of sensor is corresponding with the shape of the chip of sensor, the stream flow of chip both sides can be made in injection molding process balanced, and can make that the Material shrinkage deformed region of the product sensor of injection mo(u)lding reduces, deformed region internal stress reduces, the reduction of drawdown deformation trend.
Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, not departing from the various change and amendment done in spirit and scope of the present utility model, all should include in protection domain of the present utility model, therefore protection domain of the present utility model should be as the criterion with claim limited range.
