Description

Technical Field

[0001] This utility model relates to the field of controller detection technology, and more specifically, to a vibration detection device for controllers. Background Technology

[0002] As vehicle smart cockpit technology continues to develop, the smart cockpit domain controller, as a core control component, must undergo rigorous testing to ensure reliability. Vibration detection can simulate the vibration environment of a vehicle in motion, making the detection results more accurate.

[0003] When performing vibration testing on a controller, it is necessary to fix the controller in the vibrating equipment and make the necessary wiring connections to test its performance in the vibration environment. Typical vibration testing equipment only has vibration functionality; connecting the controller to the wiring before testing is inconvenient and results in low testing efficiency. Utility Model Content

[0004] To overcome the problem of inconvenient connection lines between vibration testing equipment and controller in the prior art, this utility model provides a vibration detection device for controller, which can effectively improve detection efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vibration detection device for a controller, the vibration detection device including a vibration table and a clamp assembly, the clamp assembly being connected to the vibration table, the clamp assembly including a clamp base, a clamping mechanism, a linear drive mechanism, and a test connector, one end of the clamping mechanism being fixedly connected to the clamp base, the other end of the clamping mechanism being used to abut against the controller to press the controller onto the clamp base, the fixed end of the linear drive mechanism being fixedly connected to the clamp base, and the moving end of the linear drive mechanism being fixedly connected to the test connector for driving the test connector to insert or disengage from the controller.

[0006] In this invention, the controller is placed on a fixture base and clamped by a clamping mechanism. The test connector is then plugged into the controller's interface. A vibration table drives the fixture assembly to vibrate, thereby performing vibration testing on the controller after the wiring is connected. The linear drive mechanism, which moves the test connector, improves testing efficiency. Furthermore, when the controller is placed on the fixture base, the linear drive mechanism can move the test connector away, avoiding structural interference. After the controller is placed on the fixture base, the linear drive mechanism can drive the test connector for connection. This significantly improves testing efficiency, especially when multiple test connectors need to be connected.

[0007] Furthermore, the clamp assembly also includes a first guide and a second guide, the first guide being fixedly connected to the clamp base, the second guide being fixedly connected to the moving end of the linear drive mechanism, and the first guide and the second guide being slidably connected along the moving direction of the linear drive mechanism.

[0008] In this design, the sliding connection between the first guide member and the second guide member guides the movement of the linear drive mechanism.

[0009] Furthermore, the fixture base is provided with a plurality of guide posts, and a fixed space for accommodating the controller is formed between the guide posts.

[0010] In this solution, a fixed space is formed by guide columns to position the controller.

[0011] Furthermore, the upper end of the guide post facing the fixed space is provided with a guide slope.

[0012] In this solution, the controller is guided into the positioning slot by a guide ramp, which improves positioning accuracy and testing efficiency.

[0013] Furthermore, the controller has a fixing part extending from its side, and the fixing part has a positioning hole in the vertical direction. The fixture base is provided with a positioning pin that is inserted into the positioning hole.

[0014] In this solution, a positioning hole is made in the fixing part to be inserted into the positioning pin on the base so as to fix the controller on the base.

[0015] Furthermore, the clamping mechanism is a rotary pressing cylinder, the fixed end of the rotary pressing cylinder is fixedly connected to the clamp base, and the moving end of the rotary pressing cylinder abuts against the fixed part to clamp the fixed part.

[0016] In this solution, the extension and rotation functions can be achieved by rotating the downward pressing cylinder, which can tighten the controller while avoiding structural interference.

[0017] Furthermore, the clamp assembly is detachably connected to the vibration table.

[0018] In this solution, the fixture components can be disassembled and replaced to suit different controller detection requirements.

[0019] Furthermore, the vibration detection device also includes a communication box, and the test connector includes a communication plug, which is electrically connected to the communication box.

[0020] In this solution, the controller is connected via a communication box and a communication plug.

[0021] Furthermore, the test connector also includes a power plug for electrical connection to an external power supply line.

[0022] In this solution, the controller is powered via a power plug.

[0023] Furthermore, the vibration detection equipment also includes an industrial control computer, which is electrically connected to the vibration table, the linear drive mechanism, and the communication box.

[0024] In this solution, the vibration table, linear drive mechanism, and communication box are controlled collaboratively by an industrial control computer, thereby improving the automation level and efficiency of the test.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] I. The vibration testing equipment of this utility model places the controller on a fixture base and clamps it with a clamping mechanism. The test connector is then plugged into the controller's interface. A vibration table drives the fixture assembly to vibrate, thereby performing vibration testing on the controller after the wiring is connected. Because a linear drive mechanism moves the test connector, the testing efficiency is improved compared to manual plugging.

[0027] II. In the vibration testing equipment of this utility model, when the controller is placed on the fixture base, the linear drive mechanism can remove the test connector, thereby avoiding structural interference between the controller and the test connector. After the controller is placed on the fixture base, the linear drive mechanism can drive the test connector to connect, which can improve testing efficiency. Attached Figure Description

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0039] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0040] Example 1

[0041] refer to Figures 1 to 7This embodiment discloses a vibration detection device for a controller, including a vibration table 1 and a fixture assembly 2. The fixture assembly 2 is connected to the vibration table 1 and includes a fixture base 21, a clamping mechanism 22, a linear drive mechanism 23, and a test connector 24. One end of the clamping mechanism 22 is fixedly connected to the fixture base 21, and the other end of the clamping mechanism 22 is used to abut against the controller 100 to press the controller 100 onto the fixture base 21. The fixed end of the linear drive mechanism 23 is fixedly connected to the fixture base 21, and the moving end of the linear drive mechanism 23 is fixedly connected to the test connector 24 to drive the test connector 24 to insert or disengage from the controller 100. The controller 100 has a plug-in interface on its side, and the test connector 24 is plugged into the plug-in interface of the controller 100.

[0042] In this embodiment, the controller 100 is placed on the fixture base 21 and clamped by the clamping mechanism 22. Then, the test connector 24 is plugged into the interface of the controller 100. The vibration table 1 drives the fixture assembly 2 to vibrate, thereby performing vibration detection on the controller 100 after the wiring is connected. Because a linear drive mechanism 23 moves the test connector 24, it can be moved away when the controller 100 is placed on the fixture base 21, thus avoiding structural interference when placing the controller 100. Placing the controller 100 on the fixture base 21 allows the test connector 24 to be driven for connection. This significantly improves testing efficiency, especially when multiple test connectors 24 need to be connected.

[0043] The connector of the controller 100 is the interface for connecting the controller 100 to external devices during operation, and is used to connect wiring during vibration detection. The test connector 24 is a connector used to connect external wiring for testing, and is used to connect to the connector of the controller 100. There can be multiple test connectors 24, each serving a different function, such as communication or power supply.

[0044] In some existing vibration testing equipment, the operator usually plugs the test connector 24 into the interface of the controller 100 one by one, and then unplugs the connector after the test is completed, so the testing efficiency is low.

[0045] In some other vibration testing equipment, the test connector 24 may be directly fixed to the fixture base 21, and the connection is completed at the same time as fixing the controller 100. However, the connector of many controllers 100 is usually not located at the bottom, but on the sides. If the position of the test connector 24 is fixed in advance, it may cause structural interference with the controller 100. That is, the test connector 24 will prevent the controller 100 from being placed into the fixture assembly 2 from top to bottom.

[0046] refer to Figures 1 to 3As shown, for example in this embodiment, the controller 100 has multiple connectors located on its four sides. When testing the controller 100, the connectors need to be connected to the test connectors 24. When the controller 100 is placed onto the fixture base 21 from above, the protruding test connectors 24 cause structural interference with the controller 100 in the vertical direction, preventing the controller 100 from being placed into the fixture base 21. In this embodiment, a linear drive mechanism 23 drives the test connectors 24 to move horizontally, thereby avoiding structural interference in the vertical direction and facilitating the connection of the test connectors 24 to the connectors of the controller 100, thus improving testing efficiency.

[0047] refer to Figures 5 to 7 In this embodiment, the clamp assembly 2 further includes a first guide member 25 and a second guide member 26. The first guide member 25 is fixedly connected to the clamp base 21, and the second guide member 26 is fixedly connected to the moving end of the linear drive mechanism 23. The first guide member 25 and the second guide member 26 are slidably connected along the moving direction of the linear drive mechanism 23. The sliding connection between the first guide member 25 and the second guide member 26 guides the movement of the linear drive mechanism 23.

[0048] Specifically, the first guide member 25 can be a guide rail, which extends along the moving direction of the linear drive mechanism 23 and is fixedly connected to the clamp base 21. The second guide member 26 can be a slider, with one end slidably connected to the guide rail and the other end fixedly connected to the moving end of the linear drive mechanism 23. In other embodiments, the first guide member 25 can be a slider and the second guide member 26 can be a guide rail, with their connection relationship adjusted accordingly. The linear drive mechanism 23 can be a cylinder, hydraulic cylinder, or electric cylinder, etc.

[0049] refer to Figures 1 to 3 as well as Figure 8 In this embodiment, the fixture assembly 2 is detachably connected to the vibration table 1. The fixture assembly 2 can be disassembled and replaced to suit different controller 100 detection requirements.

[0050] Specifically, a threaded hole is provided on the vibration table 1, and a through hole is provided on the bottom side of the fixture base 21. The fixture base 21 is connected to the vibration table 1 by screws, knobs or bolts, which facilitates the disassembly and replacement of the fixture assembly 2.

[0051] refer to Figure 1 and Figure 5In this embodiment, the vibration detection device further includes a communication box (not shown in the figure). The test connector 24 includes a communication plug 241, which is electrically connected to the communication box. The communication plug 241 may include CAN or LIN communication plugs, and the controller 100 is communicated through the communication box and the communication plug 241. The test connector 24 also includes a power plug 242, which is used to electrically connect to an external power supply line to supply power to the controller 100.

[0052] In this embodiment, the vibration testing equipment also includes an industrial control computer, which is electrically connected to the vibration table 1, the linear drive mechanism 23, and the communication box. The industrial control computer coordinates the control of the vibration table 1, the linear drive mechanism 23, and the communication box, thereby improving the automation and efficiency of the test.

[0053] refer to Figure 8 In this embodiment, the vibration detection equipment also includes a frame 5, with a vibration zone inside the frame 5 for placing the vibration table 1, which is located within the vibration zone of the frame 5. Optical grating sensors 7 are installed on both sides of the frame 5 along the vibration zone. These sensors can detect whether an operator is located within the vibration zone, providing protection. Indicator lights and control buttons 9 are also installed on the frame 5, both connected to an industrial control computer for easy operation and to display the equipment's operating status. A printer 6 is also installed inside the frame 5, connected to the industrial control computer, enabling the printing of test results into paper documents.

[0054] refer to Figure 1 In some embodiments, the vibration testing equipment may simultaneously include multiple clamping assemblies 2, each connected to the vibration table 1, enabling simultaneous testing of multiple controllers 100 and improving testing efficiency. For example, in this embodiment, two clamping assemblies 2 are fixedly connected to the vibration table 1, allowing simultaneous testing of two controllers 100. The two clamping assemblies 2 can also be integrated, forming a one-to-two testing structure.

[0055] Example 2

[0056] refer to Figure 4 This embodiment is similar to Embodiment 1, except that in this embodiment, the fixture base 21 is provided with multiple guide posts 3, and a fixed space 31 for accommodating the controller 100 is formed between the guide posts 3. The fixed space 31 refers to the space formed by the guide posts 3 to restrict the position of the controller 100. For example, in this embodiment, referring to... Figure 2A controller 100 has five guide posts 3, four of which are arranged in pairs on both sides of the controller 100, and the other guide post 3 is located at one end of the controller 100. Each guide post 3 is in contact with the controller 100, thereby restricting the position of the controller 100.

[0057] refer to Figure 1 In this embodiment, the upper side of the guide post 3 facing the fixed space 31 is provided with a guide slope 32. The guide slope 32 is generally inclined from top to bottom towards the controller 100. The slope can guide the controller 100 into the fixed space 31, thereby improving positioning accuracy and testing efficiency.

[0058] Specifically, the guide post can be approximately L-shaped, comprising a horizontal section and a vertical section. The horizontal section is fixedly connected to the fixture base 21 by bolts, and the vertical section is arranged along the vertical direction. The side of the vertical section facing the controller 100 is the guide surface, and the top of the guide surface has an inclined surface. When the controller 100 is placed in the positioning groove, the side of the controller 100 moves downward in contact with the guide surface, thereby performing guided positioning.

[0059] Example 3

[0060] refer to Figure 1 and Figure 4 This embodiment is similar to Embodiment 1 or Embodiment 2, except that in this embodiment, a fixing part 101 extends from the side of the controller 100. The fixing part 101 has a positioning hole 102 in the vertical direction, and a positioning pin 4 is provided on the clamp base 21 to be inserted into the positioning hole 102. By opening the positioning hole 102 in the fixing part 101 and inserting it into the positioning pin 4 on the base, the controller 100 can be fixed on the base.

[0061] Specifically, the controller 100 has a generally rectangular shape, and each of its four corners is provided with a fixing part 101. The fixing part 101 extends horizontally and has a vertical positioning hole 102. A positioning pin 4 is provided on the base at a position corresponding to the positioning hole 102. When the controller 100 is placed vertically on the clamp base 21, the positioning pin 4 can be inserted into the positioning hole 102.

[0062] refer to Figure 4 In this embodiment, the clamping mechanism 22 is a rotary pressing cylinder. The fixed end of the rotary pressing cylinder is fixedly connected to the clamp base 21, and the moving end of the rotary pressing cylinder abuts against the fixed part 101 to clamp the fixed part 101. The rotary pressing cylinder can realize the telescopic and rotation functions, and can avoid structural interference while clamping the controller 100.

[0063] A rotary pressing cylinder is a type of cylinder capable of reciprocating within a certain angle range. It is a pneumatic actuator that uses compressed air to drive an output shaft to reciprocate within a certain angle range. Specifically, in this embodiment, when the rotary pressing cylinder rises, it rotates to a side away from the controller 100, thus not obstructing the insertion of the controller 100. When the rotary pressing cylinder falls, it rotates to the top of the fixing part 101, thereby pressing the fixing part 101.

[0064] The vibration testing device based on at least one of the above embodiments includes the following steps in its operation: initializing the device, starting the software and loading the barcode information of the product to be tested; placing the product to be tested into the fixture for fixation and powering it on, and detecting whether the current and voltage, CAN communication and LIN communication of the product to be tested are normal; sending a signal through the host computer to make the vibration table vibrate according to the set frequency, amplitude, time and mode, and detecting whether the current and voltage, CAN communication and LIN communication of the product are normal during the vibration process; and finally printing the test results of the product through a printer.

[0065] If an error occurs during the above process when starting the software or loading the barcode information of the product to be tested, clear the error and repeat the step. If the product has not passed the current, voltage, CAN communication, and LIN communication tests before starting the vibration table, the test results will be output directly.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
