Description
Technical field
The utility model relates to automobile door handles, and in particular to capacitor door handle.
Background technique
With the development of automobile industry, automotive electronics is many kinds of, and capacitor door handle is gradually taken with its durable reliability
For mechanical switch.PCBA mainly based on encapsulating, is exactly initially charged with outside one by the technique of the PCBA of capacitor door handle encapsulation at present
In shell, liquid glue is then poured into thereto and is solidified, the interference and destruction for preventing external environment are played, to protect electronics first
Part.
But there is many drawbacks, disadvantages the most apparent in actual use for capacitor door handle system so
End is exactly that its waterproof performance is not superior, is unable to satisfy the requirement of existing design.
Furthermore existing capacitor door handle system overall structure volume is excessive, and occupied space is big, influences the late design of product
Exploitation.
Utility model content
For the problems of existing capacitor door handle system, a kind of new capacitor door handle scheme is needed.
For this purpose, the problem to be solved by the utility model is to provide a kind of low-pressure injection molding capacitor door handle systems, to overcome
The problems of prior art.
To solve the above-mentioned problems, low-pressure injection molding capacitor door handle system provided by the invention, the door handle system packet
It includes connector, harness, sensor chip, low-frequency antenna and locking induction electrode, the connector and sensor is connected to by harness
Chip, the sensor chip are connected to locking induction electrode by harness, and the low-frequency antenna is arranged in sensor core on piece
Constitute sensing main body；It is enclosed with low-pressure injection molding protective layer in the sensing main body, is enclosed with low pressure on the locking induction electrode
Injection molding protection.
Further, the harness includes two power supply lines, two signal wires, two low-frequency antenna connecting lines.
Further, the middle of sensor chip is arranged in the low-frequency antenna.
System structure provided by the utility model is provided with low-pressure injection molding protective layer on essential core chip, wraps up close
Envelope effect is good, and waterproof performance is superior, can effectively solve the problems of prior art.
Furthermore low-frequency antenna by being arranged in the middle position of sensor chip by this programme, in cooperation low-pressure injection molding
Protective layer, so that the sensing main structure constituted is compact, volume is more small.
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1 which shows the composed structure schematic diagram for the low-pressure injection molding capacitor door handle system that this example provides.
As seen from the figure, entire door handle system 10 mainly includes connector 11, harness 12, sensor chip 13, low-frequency antenna
14 and locking electrode 15 cooperation constitute.
Wherein, connector 11 is used as connecting component, and connector structure is used in this example, is easy to use in this way.The connector is logical
It crosses harness and is connected to sensor chip 13 and the connection of low-frequency antenna 14.The harness 12 is specifically made of the six roots of sensation, respectively two electricity
Source line, two signal wires, two low-frequency antenna connecting lines.Two power supply lines are connected to the power end of sensor chip 13, and two
Signal wire is connected to the signal output end of chip, and two low-frequency antenna connecting lines are connected to low-frequency antenna 14.
Low-frequency antenna 14 is integrally provided on sensor chip 13 in the present system, is specifically located at sensor chip 13
Thus middle position constitutes sensing main body.By the way that low-frequency antenna 1 to be arranged in the middle position of sensor chip 13, make
It is more compact to obtain entirely sensing main structure.
On this basis, this example is arranged in the outside for the sensing main body being made of low-frequency antenna 14 and sensor chip 13
There is one layer of low-pressure injection molding protective layer, which wraps entire sensing main body, by low-frequency antenna 14 and sensor
Chip 13 is sealed in it, and protection is formed to it.
Sensor chip 13 in this system also passes through harness and is attached with locking electrode 15.In this example, should
The outside of locking electrode 15 is again provided with one layer of low-pressure injection molding protective layer, which wraps entire locking electricity
Locking electrode 15 is sealed locking electrode module 16 formed therein that, so as to which more flexible is installed on handle shell by pole 15
In.
In addition, the low-pressure injection molding protective layer in this example is mainly made of polyamide-based hot melt glue-line, specific thickness
Depending on according to actual needs, even thick structure such as can be used or according to structure position difference, different thickness is set, non-even thickness is formed
Low-pressure injection molding protective layer.
Thus the entire capacitor door handle system constituted is by capacitance sensor, signal output, the 3 part group such as low-frequency antenna
At.In specific application, signal is acquired by corresponding CapSense acquisition module by corresponding MCU, can passed through
CapSense2 acquires external Lock signal, acquires external Unlock signal by CapSense1, MCU believes the external of acquisition
Number, PEPS is sent to by Unlock and Lock delivery outlet respectively.PEPS is by judging Unlock, Lock signal, by processing
After make corresponding movement.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
