[0001] This utility model belongs to the field of automotive grille production technology, and in particular relates to an automotive grille assembly testing device. Background Technology

[0002] The radiator grille is a structure at the front of a car used for air intake and heat dissipation. After the radiator grille is manufactured, the installation dimensions of the radiator grille mounting plate assembly need to be inspected. The radiator grille mounting plate assembly inspection device usually consists of a simulated seat and an inspection structure for the position of the mounting holes.

[0003] Existing automotive grille assembly testing equipment mostly relies on workers visually observing the correspondence between the grille mounting holes and the testing device, resulting in low testing efficiency.

[0004] To address this issue, we propose a vehicle grille assembly testing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low detection efficiency in the existing technology, and to propose an automotive grille assembly detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle grille assembly testing device includes a base plate. A hollow mounting base is fixedly connected to the top surface of the base plate. A groove for placing the grille assembly is provided in the center of the top surface of the mounting base. An annular movable plate is slidably mounted inside the mounting base. A drive assembly for moving the movable plate up and down is provided below the mounting base. Multiple movable blocks are slidably mounted inside the mounting base above the movable plate. A detection column that matches the grille assembly is provided on the top surface of each movable block. A slot is provided on the top surface of the mounting base for the detection column to extend out. Multiple annular wires are provided on the top surface of the movable plate, and the multiple wires are connected in parallel. A power supply is connected to both ends of each wire. An automatic rebound contact switch assembly is connected in series on each wire. The multiple contact switch assemblies correspond one-to-one with the multiple movable blocks, and the contact switch assembly is located directly below the corresponding movable block. Multiple indicator lights with corresponding slots are fixedly mounted on the top surface of the mounting base, and the multiple indicator lights are connected in series with the multiple contact switch assemblies. The force required to trigger the contact switch assembly is greater than the sum of the weights of the movable blocks and the detection columns.

[0008] Preferably, the contact switch assembly includes a mounting box fixedly installed on the top surface of the movable plate. The mounting box has a conductive seat that is disconnected in the middle. Both ends of the conductive seat are electrically connected to the wire. A rubber cup is provided at the disconnection point of the conductive seat, and a conductive block that matches the conductive seat is fixedly connected to the top of the inner side of the rubber cup. A pressing block that moves up and down is fixedly connected to the upper part of the mounting box. The top of the pressing block extends to the top of the mounting box, and the bottom of the pressing block fits against the top of the outer side of the rubber cup.

[0009] Preferably, a movable block is provided below the movable block and slides up and down, and a compression spring is fixedly connected between the movable block and the movable block, with the bottom end of the movable block cooperating to press the pressing block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 A vehicle grille assembly testing device includes a base plate 1, a hollow mounting base 2 fixedly connected to the top surface of the base plate 1, and a groove for placing the grille assembly 3 in the center of the top surface of the mounting base 2. (Refer to...) Figure 2-4 The mounting base 2 has an annular movable plate 4 that slides up and down inside. Below the mounting base 2 is a drive assembly that drives the movable plate 4 to move up and down. Above the movable plate 4, the mounting base 2 has multiple movable blocks 5 that slide up and down inside. The top surface of each movable block 5 has a detection column 6 that cooperates with the overall grid body 3. The top surface of the mounting base 2 has a slot 7 for the detection column 6 to extend out. (Refer to...) Figure 2-4 The top surface of the movable plate 4 is provided with multiple ring-shaped wires 8, which are connected in parallel. The two ends of the wires 8 are connected to a power supply 9. Each wire 8 is connected in series with an automatic rebound contact switch assembly. The multiple contact switch assemblies correspond one-to-one with the multiple movable blocks 5, and the contact switch assembly is located directly below the corresponding movable block 5. The top surface of the mounting base 2 is fixedly installed with multiple indicator lights 10 with corresponding slots 7, and the multiple indicator lights 10 are connected in series with the multiple contact switch assemblies. The force required to trigger the contact switch assembly is greater than the sum of the weights of the movable block 5 and the detection column 6.

[0022] Reference Figure 2-4 In use, the automotive grille assembly testing device simply requires placing the grille assembly 3 in the mounting base 2, then driving the moving plate 4 upward via the drive assembly. The contact switch assembly moves upward accordingly, causing the moving block 5 to move upward until the top of the detection column 6 engages with the misaligned mounting hole on the grille assembly 3. This triggers the contact switch assembly, illuminating the indicator light 10. Figure 5 As shown, this can conveniently indicate the misalignment of the grille's total structure 3.

[0023] Reference Figure 3-4The contact switch assembly includes a mounting box 11 fixedly mounted on the top surface of the movable plate 4. The mounting box 11 has a conductive seat 12 that is broken in the middle. Both ends of the conductive seat 12 are electrically connected to the wires 8. A rubber cup 13 is provided at the break point of the conductive seat 12, and a conductive block 14 that matches the conductive seat 12 is fixedly connected to the top of the inner side of the rubber cup 13. A pressing block 15 that moves up and down is fixedly connected to the upper part of the inside of the mounting box 11. The top of the pressing block 15 extends to the top of the mounting box 11, and the bottom of the pressing block 15 fits against the top of the outer side of the rubber cup 13.

[0024] The electric contact switch assembly deforms the rubber cup 13 by pressing down the pressing block 15 with external force. The conductive block 14 on the top inner side of the rubber cup 13 moves down until it contacts the disconnection point of the conductive base 12, thereby making the circuit conductive. When the external force disappears, the rubber cup 13 rebounds and resets the pressing block 15.

[0025] Reference Figure 3-4 A movable block 16 is provided below the movable block 5, sliding up and down. A compression spring 17 is fixedly connected between the movable block 16 and the movable block 5. The bottom end of the movable block 16 engages with the pressing block 15. The movable block 16, in conjunction with the compression spring 17, ensures that after the contact switch assembly is turned on, the compression spring 17, in conjunction with the movable block 16, provides travel for the movable plate 4 to continue moving upwards. This prevents the movable plate 4 from being limited after one contact switch assembly is triggered, thus avoiding the problem of the movable plate 4 being unable to continue detecting the remaining mounting holes.

[0026] It is important to note that the sliding motion of the movable block 16 should have a lower limit. When the movable block 16 is at the lower limit, the downward force applied by the compression spring 17 to the movable block 16 is greater than the force required for the deformation of the rubber cup 13, thus avoiding insufficient sensitivity in the trigger detection. The aforementioned lower limit can be achieved by setting a limit block at the bottom of the moving stroke of the movable block 16, which is quite common and will not be elaborated further.

[0027] Reference Figure 1 , Figure 3 Although the weight of the grating assembly 3 is generally much greater than the force required for the deformation of the rubber cup 13 and the compression spring 17, the grating assembly 3 is easily affected by interference during testing in actual use, and it is difficult to achieve stable testing relying solely on its own weight. To solve this problem, a threaded hole 18 is provided through the top surface of the mounting base 2. A threaded post 19 is threaded into the threaded hole 18, and a handle 20 is fixedly connected to the top of the threaded post 19. A pressure plate 21 that mates with the grating assembly 3 is fixedly connected to the middle of the threaded post 19. The operator screws the threaded post 19 into the threaded hole 18 through the handle 20 until the bottom surface of the pressure plate 21 presses tightly against the top surface of the grating assembly 3, thereby achieving auxiliary fixation of the grating assembly 3 and avoiding the problem of unstable testing relying solely on the grating assembly 3.

[0028] The drive assembly includes two electric actuators 22 fixedly mounted on the bottom surface of the base plate 1. The top ends of the telescopic sections of the electric actuators 22 extend into the mounting base 2 and are fixedly connected to the bottom surface of the movable plate 4. The two electric actuators 22 are located on opposite sides of the bottom surface of the movable plate 4. This drive assembly, through the two symmetrically arranged electric actuators 22, provides a stable driving force for the up-and-down movement of the movable plate 4, avoiding the problem of unstable movement caused by uneven force during the movement of the movable plate 4, thus improving stability and service life.

[0029] A reminder sticker 23 is affixed to the top side of the detection column 6. Through the reminder sticker 23, it is possible to clearly observe whether the detection column 6 passes through the mounting hole of the grid body 3, realizing a secondary confirmation step and improving the detection accuracy.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
