Description

Technical Field

[0001] This utility model relates to the field of engine mount testing technology, specifically to an automotive engine mount testing device. Background Technology

[0002] Engine mounts are support and vibration damping components that connect the engine to the vehicle body. They isolate engine vibrations and noise from being transmitted into the passenger compartment, significantly improving overall vehicle comfort. Engine mounts are primarily used in passenger cars for engine support.

[0003] However, the existing technology for testing suspension brackets still has the following drawbacks:

[0004] In existing technologies, when testing suspension brackets, it is mostly necessary to install the suspension brackets on the car, then install the engine on the suspension brackets, and start the car to test the suspension brackets. However, this operation is cumbersome and greatly increases the difficulty of the work.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide an automotive engine mounting bracket testing device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automotive engine mount testing device, comprising:

[0009] The base plate has fixing components connected to both sides of the middle of the upper end face of the base plate;

[0010] Vibration reinforcement components: all four vibration reinforcement components are connected to the four corners of the lower end face of the base plate;

[0011] The vibration assembly comprises two vibration assemblies connected to both sides of the upper end face of the base plate. Each vibration assembly includes a dual-axis motor fixedly connected to the upper end face of the base plate. The front and rear drive ends of the dual-axis motor are both fixedly connected to rotating shafts, and the ends of the two rotating shafts away from the dual-axis motors are both fixedly connected to eccentric discs.

[0012] Furthermore, the fixing component includes:

[0013] Guide rod, the guide rod is fixedly connected to the upper end face of the base plate;

[0014] The T-shaped groove is opened in the guide rod;

[0015] Fixing holes: Several fixing holes are opened on the inside of the guide rod.

[0016] Furthermore, two sliding seats are slidably connected in the T-shaped groove, and suspension brackets are connected to the two sliding seats.

[0017] Furthermore, the vibration enhancement component includes:

[0018] Telescopic rod, which is fixedly connected to the lower end face of the base plate;

[0019] A spring, which is sleeved on the telescopic rod;

[0020] A support plate is fixedly connected to the lower end of the telescopic rod.

[0021] Furthermore, a demonstration engine is connected between the two suspension brackets.

[0022] The advantages of this invention compared to existing technologies are as follows:

[0023] 1. The detection device of this utility model is set as a separate component. By setting up a vibration component and a vibration enhancement component, the dual-axis motor drives the eccentric disk to rotate, which drives the base plate to vibrate. At the same time as the vibration, the base plate transfers kinetic energy to the telescopic rod and spring. The spring continuously compresses and rebounds, simulating the vibration scenario of a car. Compared with the detection on the car, the cumbersomeness of the detection is greatly reduced and the detection efficiency is improved. Attached Figure Description

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0030] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0031] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the technical solution of this utility model is as follows: a car engine mount testing device, comprising: a fixing assembly 2 connected to both sides of the middle of the upper end face of a base plate 1; four vibration strengthening assemblies 7 connected to the four corners of the lower end face of the base plate 1; and two vibration assemblies 6 connected to both sides of the upper end face of the base plate 1. Each vibration assembly 6 includes a dual-axis motor 601 fixedly connected to the upper end face of the base plate 1. The front and rear drive ends of the dual-axis motor 601 are fixedly connected to rotating shafts 602. The ends of the two rotating shafts 602 away from the dual-axis motor 601 are fixedly connected to eccentric disks 603. The dual-axis motor 601 provides power for the rotation of the eccentric disks 603. The two eccentric disks 603 form a group. At the same time, the two dual-axis motors 601 do not rotate synchronously, so that the eccentric wheels on the vibration assemblies 6 on both sides also do not rotate synchronously, thereby strengthening the vibration frequency of the device.

[0033] like Figure 2 and Figure 3 As shown, the fixing component 2 includes a guide rod 201 fixedly connected to the upper end face of the base plate 1, a T-shaped slide groove 202 opened in the guide rod 201, which facilitates the installation of the sliding seat 3 onto the guide rod 201, several fixing holes 203 are opened on the inner side of the guide rod 201, two sliding seats 3 are slidably connected in the T-shaped slide groove 202, and the fixing holes 203 facilitate the fixing of the sliding seats 3, and a suspension bracket 4 is connected to the two sliding seats 3, which facilitates the installation of the demonstration engine 4.

[0034] like Figure 4As shown, the vibration enhancement component 7 includes a telescopic rod 701 fixedly connected to the lower end face of the base plate 1, a spring 702 sleeved on the telescopic rod 701, a support plate 703 fixedly connected to the lower end of the telescopic rod 701, and a demonstration engine 5 connected between the two suspension brackets 4. The telescopic rod 701 and the spring 702 cooperate to guide and repeatedly rebound the spring 702.

[0035] In practical use, the device is placed in a suitable position, and then the sliding seat 3 is slid to the suitable position. Then, the sliding seat 3 is limited and fixed by bolts and other parts passing through the fixing hole 203. Then, the suspension bracket 4 is installed on the sliding seat 3 by bolts and other parts. The demonstration engine 5 is placed on the suspension bracket 4 and fixed by bolts and other parts. Then, the demonstration engine 5 is started to test the suspension bracket 4. At the same time, the dual-axis motor 601 is started to drive the eccentric disk 603 to rotate, causing the base plate 1 to vibrate, which drives the spring 702 to continuously compress and rebound, simulating the vibration environment of a car.

[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure.
