Description

Technical Field

[0001] The utility model belongs to the field of sensors, and particularly relates to a 14PIN sensor. Background Art

[0002] With the rapid development of the automobile industry, radar probes have become an indispensable component in automobiles. Currently, there are various types of radar probe products on the market, and the number of bits of data transmission ranges from 2PIN to 6PIN, with most of them being 3PIN. This type of radar probe occupies the main market and is distributed in various types of vehicles to perform radar sensing and transmission work to meet the realization of vehicle assisted driving functions.

[0003] The 2PIN, 3PIN, 4PIN, and 6PIN radar probes currently on the market can meet the current functional requirements of radar sensing. However, due to the limitation of installation space, the current product appearance is designed to be relatively small, so the number of PIN positions is relatively small, the signal source that can be transmitted is limited, and its sensing function is relatively weak. Therefore, more probes need to be installed in the radar sensing system on each vehicle to meet the functional requirements and remedy its weakness with quantity. Obviously, this method is not the most ideal method. Increasing the number of probes will increase the complexity of the process, increase the cost of components, increase the probability of failure, and increase the difficulty of maintenance. Therefore, in order to comply with the current development trend of the automotive industry, the current radar probes still have a lot of room for improvement. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a 14PIN ultrasonic radar sensor body, which is designed with a 14PIN signal transmission channel, increases the number of transmission interfaces, and enhances the radar sensing transmission function; thereby reducing the number of probes installed in the radar system, thereby simplifying the system process, reducing costs, failure probability and maintenance difficulty.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A 14-pin ultrasonic radar sensor body, characterized in that the sensor body is provided with a receiving cavity for placing a PCB integrated circuit and a plug-in cavity for mating and connecting with an external wiring harness end connector, and fourteen groups of PIN needle assemblies are fixedly arranged on the sensor body, the head ends of the fourteen groups of PIN needle assemblies are arranged in the receiving cavity, and the tail ends of the fourteen groups of PIN needle assemblies are arranged in the plug-in cavity.

[0007] In the radar sensor body, based on the setting of fourteen groups of PIN needle components, it has 14 PIN signal transmission channels, increases the number of transmission interfaces, and enhances the radar sensing transmission function. This reduces the number of probes installed in the radar system, thereby simplifying the system process, reducing costs, failure probability, and maintenance difficulty.

[0008] Furthermore, the sensor body and the fourteen PIN needle assemblies are integrally formed. The integral forming means that the sensor body is injection molded on the fourteen PIN needle assemblies, which can make the PIN needle assemblies unnecessary to be welded and assembled, and can effectively reduce assembly costs.

[0009] Furthermore, the accommodating cavity is located at the lower side of the front end of the sensor body, and the connecting and plugging cavity is located at the rear side of the rear end of the sensor body.

[0010] Furthermore, a mounting groove for mounting an external detector is provided on the upper side of the sensor body, a connecting through hole for mounting a probe core is provided on the mounting groove, and the mounting groove is connected with the accommodating cavity via the connecting through hole.

[0011] Furthermore, a plurality of PCB installation positioning posts for positioning the PCB during installation are arranged in the accommodating cavity.

[0012] Furthermore, a first mounting buckle position is fixedly provided on the sensor body for ensuring that the radar sensor body and the external connector wire end are firmly mounted, and the first mounting buckle position is located at the lower side of the rear end of the sensor body.

[0013] Furthermore, a positioning rib is provided at the rear end of the sensor body for positioning and preventing errors when the sensor body is connected to an external wiring harness end connector.

[0014] Furthermore, a second installation buckle position is provided at the front end of the sensor body to cooperate with the installation position in the vehicle.

[0015] Furthermore, the sensor body is made of PA66-GF30 material, and the PIN needle assembly is made of C5191 material.

[0016] Furthermore, the PIN needle assembly includes a first PIN needle and a second PIN needle, the first PIN needle and the second PIN needle are fixedly arranged in the sensor body, and the first PIN needle head end and the second PIN head end are arranged in the accommodating cavity, and the first PIN needle tail end and the second PIN tail end are arranged in the plug-in cavity. Based on the PIN needle assembly being a double PIN needle arrangement, the spacing when arranging the PIN needles can be reduced to realize the arrangement design of the 14PIN signal transmission channel.

[0017] In the utility model, the beneficial effect is that based on the setting of fourteen groups of PIN needle components, it has 14 PIN signal transmission channels, increases the number of transmission interfaces, and enhances the radar sensing transmission function. In turn, the number of probes installed in the radar system is reduced, thereby simplifying the system process, reducing costs, failure probability and maintenance difficulty.
