Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to an intake air pressure sensor for automobiles. Background Art

[0002] The intake air pressure sensor is referred to as MAP. It is connected to the intake manifold with a vacuum tube. With different engine speed loads, it senses the vacuum changes in the intake manifold, and then converts the changes in the internal resistance of the sensor into a voltage signal for the ECU to correct the injection amount and ignition timing angle. During the use of the automobile intake air pressure sensor, the automobile intake air pressure sensor needs to be electrically connected to the ECU interface to detect the oil and gas pressure of the intake manifold, and for the ECU to correct the injection amount and ignition timing angle.

[0003] An automotive intake pressure sensor disclosed in publication number CN219798596U, by setting one end of the mounting bolt as a plum blossom socket, does not need to be replaced with a torque wrench, so that the owner can disassemble and maintain it by himself, and reduces the maintenance cost of the automotive intake pressure sensor. The mounting bolt axially stretches the connection between the sensor mounting seat and the vehicle body through a gasket and a sensor mounting clamping mechanism, thereby improving the screwing strength between the mounting bolt and the vehicle body, so that the non-torque wrench installation can ensure the fixing strength of the sensor and the vehicle body, and makes the sensor not easy to shake or fall off.

[0004] However, this automotive intake pressure sensor has the following disadvantages:

[0005] When installing the pressure sensor, the pressure sensor is prone to positional displacement due to inaccurate positioning, and after the pressure sensor is installed, the pressure sensor is prone to fall off due to vibration of the car. Utility Model Content

[0006] The technical problem solved by the utility model is to provide an automobile intake pressure sensor which is highly practical, can be simply operated and has a relatively simple structure. It solves the problem raised in the above background technology that when the pressure sensor is installed, the pressure sensor is easily displaced due to inaccurate positioning, and after the pressure sensor is installed, the pressure sensor is easily fallen off due to vibration of the automobile.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: an intake pressure sensor for automobiles, comprising a protective cover, a pressure sensor is arranged inside the protective cover, a limit frame is arranged at the input end of the pressure sensor, a clamping assembly is arranged inside the limit frame, mounting plates are fixedly installed on both sides of the protective cover, through grooves are opened on both sides of the surface of the mounting plate, and an anti-falling assembly is arranged inside the through groove.

[0008] Optionally, the clamping assembly includes a plurality of damping rods fixedly mounted inside the protective cover, a spring is sleeved on the surface of the damping rod, and a positioning block is fixedly mounted on the top of the damping rod.

[0009] Optionally, a connecting rod is fixedly installed at the bottom of the protective cover, and a transmission line is provided at the bottom of the connecting rod.

[0010] Optionally, the anti-falling component includes a threaded bolt with threads passing through the inside of the through groove, the surface of the threaded bolt is provided with an anti-skid plate, the bottom of the anti-skid plate is provided with a friction plate, and the bottom of the friction plate is provided with a rubber pad.

[0011] Optionally, a plurality of clamping plates are provided at the bottom of the anti-slip plate, and limiting plates are provided at the four corners of the surface of the friction plate.

[0012] Optionally, the surfaces of the clamping plate and the limiting plate are in contact, and the clamping plate can resist and clamp the limiting plate.

[0013] The utility model provides an intake air pressure sensor for an automobile, which has the following beneficial effects:

[0014] 1. The automobile intake pressure sensor is provided with a limit frame and a clamping assembly. During use, a person inserts the plug connector into the limit frame, and then the positioning block inside the limit frame clamps the plug connector, thereby improving the efficiency of connecting the limit frame and the automobile.

[0015] 2. The automotive intake pressure sensor is equipped with a mounting plate and an anti-fall-off component. In the process of more than ten steps, personnel will thread the threaded bolt and the mounting plate. Subsequently, the anti-slip plate and the friction plate will rub against each other. After the friction, the rubber pad will contact the mounting plate, thereby improving the anti-slip property of the pressure sensor and reducing the possibility of the pressure sensor falling off due to vibration during installation.
