Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water temperature sensor equipment, in particular to a device for detecting the shell strength of an NTC automobile water temperature sensor. Background Art
[0002] Automotive sensors are input devices for automotive computer systems. They convert various operating information during vehicle operation, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmit them to the computer so that the engine is in the best working condition. There are many automotive sensors. When judging a sensor failure, one should not only consider the sensor itself, but the entire circuit where the failure occurs. Therefore, when looking for a fault, in addition to checking the sensor, one should also check the wiring harness, connectors, and related circuits between the sensor and the electronic control unit.
[0003] Application number CN202223435175.4 discloses an electrical inspection device for automotive sensor housing PIN pins, relating to the technical field of PIN pin electrical inspection devices. The device comprises a test platform, a fixing frame, and a sensor housing PIN pin. The device utilizes a test chamber, a test pin assembly, a contact sensor, and an indicator light. When testing a sensor housing PIN pin, the sensor housing PIN pin can be positioned on top of the test chamber. Upon activation, the cylinder assembly drives the sensor housing PIN pin downward through its pressing end. The bottom end of the sensor housing PIN pin contacts the top end of the test pin assembly, which in turn pushes the bottom end of the test pin assembly downward. If the product passes inspection, the bottom end of the test pin assembly contacts the contact sensor, and the corresponding indicator lights illuminate. If the product fails inspection, the indicator lights corresponding to the failed PIN pin remain off.
[0004] The above-mentioned document discloses an electrical inspection device for the PIN needle of an automobile sensor housing, which has the following defects: when inspecting the sensor housing, the device needs to fix the sensor to the inspection needle assembly for easy inspection. However, when the sensor size is different, the force required to press the cylinder will also be different, otherwise the sensor PIN needle may be damaged. This structure cannot adapt to sensors of different sizes for electrical inspection and testing.
[0005] It can be seen from this that the existing electrical detection device does not have the function of adapting to sensors of different sizes for electrical detection testing. It is necessary to improve the existing deficiencies and provide a device that can adapt to sensors of different sizes for electrical detection testing. Utility Model Content
[0006] The purpose of the utility model is to provide a device for detecting the strength of the housing of an NTC automobile water temperature sensor, so as to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0008] The utility model is a device for detecting the shell strength of an NTC automobile water temperature sensor, comprising a device body, a detection component and a discharge component, wherein the detection component and the discharge component are mounted on the upper surface of the device body, and the discharge component is located below the detection component.

The purpose of this arrangement is that during the use of the detection device, the display screen is maintained in operation by the host, the detection range of the sensor to the detector is controlled by the display screen, the device is lifted up by the handle, the detector performs an electrical test on the sensor, the fixing rod is vertically fixed to the host by the positioning block, the sensor is placed in the mounting groove of the sliding plate for limit, the handle is pressed down by the hand, the handle drives the hinge blocks on both sides to rotate together, the bottom end of the hinge block is affected by the top end and moves downward together, the hinge block generates a force on the slide bar, the slide bar is driven by the hinge block to slide downward in the mounting frame, and the slide bar drives the pressure plate downward when it moves downward, and the pressure plate is fixed by two support rods so that the pressure plate is vertical. When the pressure plate is pressed downward, it pushes the sensor on the mounting groove downward, and the pressure is transmitted downward to the sliding plate through the sensor. The sliding plate slides downward outside the fixed rod. When the sliding plate slides to fit the upper surface of the detector, the ejector pin of the detector passes through the sliding plate and extends to the lower surface of the sensor, thereby electrically detecting the PIN pin of the sensor. When the pressure on the handle disappears, the first compression spring squeezed by the pressure plate rebounds upward to drive the pressure plate and the sliding rod to reset. The second compression spring squeezed and contracted by the sliding plate rebounds upward to drive the sliding plate to reset. This structure expands the activity space of the sensor, so that sensors of different sizes can be installed on the sliding plate for detection by the detector, thereby improving the flexibility of the device.
[0009] Furthermore, positioning blocks are provided on the outer walls of the main unit near the detector, and the four positioning blocks are respectively sleeved on the outer walls of the bottom ends of the four fixing rods. The purpose of this arrangement is to fix the fixing rods vertically on the main unit through the positioning blocks during use of the detection device.
[0010] Furthermore, the main unit is equipped with control keys on the front, a display screen is mounted on one side of the main unit's top outer wall, and handles are rotatably connected to the main unit's outer walls on both sides. This arrangement allows the main unit to maintain the display screen in operation during use, control the detector's sensor detection range through the display screen, and lift the device with the handles.
[0011] Furthermore, a fixing base is mounted on the upper surface of the main unit near the display screen, and two support rods are provided on the side of the fixing base where the main unit is close to the fixing base, with the two support rods located on either side of the fixing base. This arrangement is intended to ensure that when the detection device is in use, the downward movement of the sliding rod drives the pressure plate downward with it, and the pressure plate is fixed by the two support rods, allowing the pressure plate to move vertically downward and horizontally.
[0012] Furthermore, a mounting bracket is mounted on the front of the fixing seat, a slide bar is slidably connected to the inner wall of the mounting bracket, hinge blocks are hingedly connected to the outer walls on both sides of the top of the slide bar, and a handle bar is hingedly connected to the outer wall on the top side where the two hinge blocks are close to each other. The purpose of this arrangement is that when the detection device is in use, the handle bar is held and pressed downward, and the handle bar drives the hinge blocks on both sides to rotate together. The bottom ends of the hinge blocks are affected by the top ends and move downward together, and the hinge blocks exert a force on the slide bar, and the slide bar is driven by the hinge blocks to slide downward in the mounting bracket, and the downward movement of the slide bar drives the pressure plate downward together.
[0013] Furthermore, a pressure plate is mounted at the bottom end of the slide rod, one side of which is slidably connected to the outer walls of the two support rods, and a compression spring is mounted on the surface where the pressure plate and the support rods are in contact. This arrangement is intended to ensure that when the pressure on the handlebar is released during use of the detection device, the compression spring, squeezed by the pressure plate, rebounds upward, driving the pressure plate and slide rod to reset.
[0014] The utility model has the following beneficial effects:
[0015] (1) The utility model is provided with a compression spring 2 and a sliding plate. The compression plate presses the sensor on the mounting groove downward, and the pressure is transmitted downward to the compression spring 2 through the sensor. When the sliding plate slides to fit the upper surface of the detector, the top pin of the detector passes through the sliding plate and extends to the lower surface of the sensor, thereby electrically detecting the PIN pin of the sensor. When the pressure disappears, the compression spring 2 squeezed and contracted by the sliding plate rebounds upward to drive the sliding plate to reset. This structure expands the activity space of the sensor, so that sensors of different sizes can be installed on the sliding plate for detection by the detector, thereby improving the flexibility of the device.

When the sliding plate 302 slides to fit the upper surface of the detector 105, the ejector pin of the detector 105 passes through the sliding plate 302 and extends to the lower surface of the sensor, thereby electrically detecting the PIN pin of the sensor. When the pressure on the handle 205 disappears, the compression spring 1 208 squeezed by the pressure plate 206 rebounds upward, driving the pressure plate 206 and the sliding rod 203 to reset.

[0026] Positioning blocks 106 are provided on the outer walls of the main unit 101 near the detector 105.

[0028] A fixing base 201 is mounted on the upper surface of the main unit 101, near the display screen 103. Two support rods 207 are located on the side of the fixing base 201 where the main unit 101 is in contact. The two support rods 207 are located on either side of the fixing base 201.

A compression spring 208 is mounted on the side where the pressure plate 206 and the support bars 207 meet.
