Description

Technical Field

[0001] This utility model relates to the field of sensor housing testing, specifically to a device for testing the strength of a vehicle-mounted acceleration sensor housing. Background Technology

[0002] As a core component of vehicle safety control systems (such as ABS and ESP), the reliability of vehicle-mounted acceleration sensors is directly related to driving safety. The structural strength of the vehicle-mounted acceleration sensor housing is a key factor in ensuring its normal operation under complex conditions, especially in harsh environments such as mechanical shocks and vibrations that vehicles may encounter during driving. Currently, strength testing devices are usually used to test the housing of vehicle-mounted acceleration sensors.

[0003] Currently, some strength testing devices test the strength of vehicle-mounted accelerometer sensor housings by placing the housing on a testing platform, applying a preset pressure to the housing using hydraulic equipment, and then checking for deformation or damage. However, this method has the following drawbacks:

[0004] The detection efficiency is relatively low, making it inconvenient to conduct large-scale strength testing of vehicle-mounted acceleration sensor housings. Furthermore, when non-conforming products are detected, they cannot be effectively separated from qualified products, requiring secondary manual screening, which increases labor costs.

[0005] The testing process lacks simulation of environmental factors such as temperature, resulting in a discrepancy with real-world working conditions, and the reliability of the test results needs further improvement.

[0006] To address this, we propose a device for testing the strength of the housing of an on-board acceleration sensor. Utility Model Content

[0007] The purpose of this utility model is to provide a vehicle-mounted acceleration sensor housing strength testing device, which solves the technical problems of existing strength testing devices having low testing efficiency, being inconvenient for large-scale strength testing of vehicle-mounted acceleration sensor housings, and being unable to effectively separate unqualified products from qualified products when they are detected, requiring secondary manual screening and increasing labor costs.

[0008] This utility model achieves the above objectives through the following technical solutions:

[0009] A vehicle-mounted acceleration sensor housing strength testing device includes a testing device and a conveyor belt mechanism for conveying the vehicle-mounted acceleration sensor housing. It also includes a stamping mechanism mounted on the conveyor belt mechanism for stamping the vehicle-mounted acceleration sensor housing. Two sets of side baffles are symmetrically arranged on both sides of the stamping mechanism, respectively abutting the two sides of the conveyor belt. The testing device is located on one side baffle of the stamping mechanism and is used to test the stamped vehicle-mounted acceleration sensor housing. A push plate, driven by a telescopic device, is also embedded in this side baffle. A corresponding movable opening is provided on the other side baffle. When the testing device detects a defective vehicle-mounted acceleration sensor housing, it controls the telescopic device to drive the push plate to push the defective housing out of the movable opening.

[0010] A further improvement is that the stamping mechanism includes a mounting housing sleeved on the outside of the conveyor belt, a cavity is formed inside the mounting housing, an inlet and an outlet are respectively formed on both sides of the mounting housing for the upper section of the conveyor belt to pass through and communicate with the cavity, an movable opening is also formed through the mounting housing for the lower section of the conveyor belt to pass through, a hydraulic device is provided on the mounting housing, the output end of the hydraulic device extends into the cavity and is connected to a pressure head, a mounting plate is provided in the cavity, and a number of pressure sensors electrically connected to the hydraulic device are provided on the mounting plate, the detection end of the pressure sensor is connected to a contact plate for contacting the bottom wall of the upper section of the conveyor belt, and the contact plate corresponds to the pressure head.

[0011] A further improvement is that a detector is provided on the inner wall of the cavity. When the detector detects that the housing of the vehicle acceleration sensor has moved to a preset position above the contact plate, the hydraulic equipment is controlled to drive the pressure head to perform a stamping operation while the conveyor belt mechanism is stopped.

[0012] A further improvement is that the outer walls on both sides of the mounting housing are slidably provided with sealing plates for closing the inlet or outlet, and the sealing plates are driven to rise and fall by a telescopic device provided on the mounting housing.

[0013] A further improvement is that the side wall of the mounting housing is also provided with an air outlet that communicates with the cavity, and the air outlet is connected to an external heating device or an external cooling device through a pipe.

[0014] A further improvement is that a number of sets of ball bearings are embedded on the side of the contact plate away from the pressure sensor.

[0015] A further improvement is that the conveyor belt mechanism, the stamping mechanism, and the side baffle are all located on the workbench, and a collection box is provided on the side of the workbench located at the opening to receive defective vehicle acceleration sensor housings pushed out from the opening.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model can transport vehicle-mounted acceleration sensor housings via a conveyor belt mechanism. During the transport process, the vehicle-mounted acceleration sensor housings are stamped and tested sequentially by a stamping mechanism and a testing device, which improves testing efficiency and facilitates the strength testing of large batches of vehicle-mounted acceleration sensor housings. Furthermore, when the testing device detects unqualified vehicle-mounted acceleration sensor housings, it controls the telescopic device to push the push plate to push the unqualified vehicle-mounted acceleration sensor housings out of the movable port, thereby achieving automatic separation and screening and reducing the labor intensity of manual post-processing.

[0018] This utility model's impact mechanism can seal the inlet and outlet of the vehicle-mounted acceleration sensor housing after it enters the installation housing cavity via a conveyor belt mechanism. At the same time, the temperature inside the cavity can be adjusted by using an air outlet in conjunction with external heating or cooling equipment to simulate the temperature environment under real working conditions. This allows the housing to undergo impact testing under preset temperature conditions, thereby improving the reliability of the test results. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] Please see the appendix Figure 1-3A vehicle-mounted acceleration sensor housing strength testing device includes a testing device 3 and a conveyor belt mechanism 1 for conveying the vehicle-mounted acceleration sensor housing;

[0027] The aforementioned testing equipment 3 and conveyor belt mechanism 1 are both conventional equipment in this field. Specifically, the testing equipment 3 includes an image acquisition module (such as a camera), a comparison module, and a database storing qualified vehicle accelerometer housing image data. The image acquisition module acquires vehicle accelerometer housing image data and transmits it to the comparison module. The comparison module compares the acquired vehicle accelerometer housing image data with the qualified vehicle accelerometer housing image data in the database to make a judgment.

[0028] The conveyor belt mechanism 1 includes a conveyor belt, a drive roller, a driven roller, a support frame, and a rotary motor, among other structures.

[0029] Of course, the aforementioned testing equipment 3 and conveyor belt mechanism 1 are not limited to the two types mentioned above;

[0030] It also includes a stamping mechanism 2 mounted on the conveyor belt mechanism 1 for stamping the housing of the vehicle-mounted acceleration sensor. Two sets of side baffles 4 are symmetrically arranged on both sides of the stamping mechanism 2, and the two sets of side baffles 4 are respectively attached to both sides of the conveyor belt of the conveyor belt mechanism 1, as shown in the attached figure. Figure 1 As shown, there are four sets of side baffles 4. The side baffles 4 are used to restrict the vehicle-mounted acceleration sensor housing conveyed on the conveyor belt mechanism 1 so that it will not fall off the side of the conveyor belt.

[0031] The testing device 3 is located on a side baffle 4 on one side of the stamping mechanism 2. It is used to test the vehicle acceleration sensor housing after stamping. The vehicle acceleration sensor housing is conveyed by the conveyor belt mechanism 1, stamped by the stamping mechanism 2, and then conveyed by the conveyor belt mechanism 1 to the testing device 3 for testing.

[0032] The side baffle 4 is also fitted with a push plate 5 that is driven to move by the telescopic device 2 8. The telescopic device 2 8 can be installed on the side wall of the side baffle 4. The other side baffle 4 is provided with a movable opening 6 corresponding to the push plate 5. The movable opening 6 allows the vehicle-mounted acceleration sensor housing to pass through. Preferably, both the movable opening 6 and the push plate 5 correspond to the detection device 3.

[0033] Specifically, the testing device 3, the telescopic device 2 8, and the conveyor belt mechanism 1 are all electrically connected to an external controller. The conveyor belt mechanism 1 transports the vehicle acceleration sensor housing, which has been stamped by the stamping mechanism 2, to the testing device 3 and then stops transporting it. The testing device 3 performs testing. When the testing device 3 detects a defective vehicle acceleration sensor housing, it sends a signal to the external controller. The external controller controls the telescopic device 2 8 to drive the push plate 5 to push the defective vehicle acceleration sensor housing out of the movable port 6. Similarly, if the vehicle acceleration sensor housing is qualified, it sends a signal to the external controller, which then controls the conveyor belt mechanism 1 to continue transporting it.

[0034] Preferably, in this embodiment, the conveyor belt mechanism 1, the stamping mechanism 2, and the side baffle 4 are all located on the workbench. A collection box 7 is provided on one side of the workbench located at the movable opening 6 to receive the defective vehicle acceleration sensor housing pushed out from the movable opening 6. An elastic pad (such as one made of rubber material) can be placed inside the collection box 7 to prevent further damage to the vehicle acceleration sensor housing that enters the collection box 7.

[0035] Example 2

[0036] Please see the appendix Figure 1 Appendix Figure 3 -Appendix Figure 4Based on Embodiment 1, the stamping mechanism 2 of this embodiment includes a mounting housing 21 sleeved on the outside of the conveyor belt. A cavity is formed inside the mounting housing 21. An inlet and an outlet are respectively formed on both sides of the mounting housing 21, allowing the upper section of the conveyor belt to pass through and communicate with the cavity. The inlet and outlet facilitate the conveyor belt driving the onboard acceleration sensor housing into or out of the cavity. An movable opening 6 is also formed through the mounting housing 21, allowing the lower section of the conveyor belt to pass through. A hydraulic device 24 (such as a hydraulic cylinder) is provided on the mounting housing 21. The output end of the hydraulic device 24 extends into the cavity and is connected to a pressure head 25. A mounting plate 29 is provided inside the cavity. Several sets of pressure sensors 210 electrically connected to the hydraulic device 24 are provided on the mounting plate 29. The pressure sensors 210 are conventional structures in the art and will not be described in detail here. The detection end of the pressure sensor 210... A contact plate 27 is connected to the bottom wall of the upper section of the conveyor belt. The contact plate 27 corresponds to the pressure head 25. Several sets of balls are embedded on the side of the contact plate 27 away from the pressure sensor 210. The balls reduce the contact wear between the contact plate 27 and the conveyor belt. Specifically, the pressure sensor 210 and the hydraulic device 24 are electrically connected to an external controller. When the vehicle acceleration sensor housing moves above the contact plate 27 through the conveyor belt mechanism 1, the conveyor belt mechanism 1 stops conveying. At this time, the hydraulic device 24 drives the pressure head 25 to press the vehicle acceleration sensor housing. The pressure is transmitted to the pressure sensor 210 through the conveyor belt and the contact plate 27. When the pressure sensor 210 detects that the pressure has reached a preset threshold, the pressure sensor 210 sends a signal to the external controller. The external controller controls the hydraulic device 24 to reset and also controls the conveyor belt mechanism 1 to continue conveying.

[0037] Preferably, the inner wall of the cavity in this embodiment is provided with a detector 26 (such as an infrared sensor, a photoelectric sensor, etc.), and the detector 26 is connected to an external controller.

[0038] When the detector 26 detects that the housing of the vehicle-mounted acceleration sensor has moved to a preset position above the contact plate 27, it sends a signal to the external controller. The external controller controls the hydraulic equipment 24 to drive the pressure head 25 to perform the stamping operation and at the same time controls the conveyor belt mechanism 1 to stop.

[0039] Preferably, in this embodiment, sealing plates 22 for sealing the inlet or outlet are slidably provided on both outer walls of the mounting housing 21. The sealing plates 22 are driven to rise and fall by telescopic devices 23 (such as electric telescopic rods) provided on the mounting housing 21. After the vehicle-mounted acceleration sensor housing enters the mounting housing 21 with the conveyor belt mechanism 1, the sealing plates 22 can be driven downward to fit against the conveyor belt by the telescopic devices 23, thereby sealing the cavity. Preferably, a rubber sealing strip is embedded in the bottom wall of the sealing plate 22 to ensure the sealing of the contact position between the sealing plate 22 and the conveyor belt.

[0040] The side wall of the mounting housing 21 is also provided with an air outlet 28 that communicates with the cavity. The air outlet 28 is connected to an external heating device or an external cooling device through a pipe. The external heating device is used to supply hot air into the cavity through the air outlet 28 to heat the vehicle accelerometer housing inside the cavity. The external cooling device is used to supply cold air into the cavity through the air outlet 28 to reduce the temperature of the vehicle accelerometer housing inside the cavity. Of course, the heating device or cooling device mentioned above is not limited to this gas supply device. If the temperature is adjusted by supplying gas, the side wall of the mounting housing 21 should also be provided with a pressure relief valve or the like that that communicates with the cavity to regulate the internal air pressure. Preferably, a temperature sensor is also provided inside the cavity to control the temperature of the vehicle accelerometer housing inside the mounting housing 21, simulate the temperature environment under real working conditions, and improve the reliability of the test results by controlling the vehicle accelerometer housing to be stamped at different temperatures.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
