[0002] In vehicle body stiffness testing, displacement sensors are key measurement tools, mainly used to quantify the degree of deformation of the vehicle body under stress, thereby indirectly assessing stiffness.

[0003] Patent application number 202121395383.9 discloses a passenger vehicle body torsional stiffness testing device, comprising a displacement measuring mechanism including a magnetic base, a first positioning block, a first displacement sensor, a magnetic base connecting rod clamp, an adjusting rod, and a magnetic base connecting rod; the magnetic base is connected to the floor; the magnetic base connecting rod is connected to the magnetic base, and the magnetic base connecting rod is fixedly connected to both the middle and top ends of the magnetic base connecting rod; the adjusting rod is connected to the magnetic base connecting rod clamp; the first positioning block is connected to the top end of the adjusting rod, and the first displacement sensor is connected to the first positioning block.

[0004] The disadvantages of the displacement measuring mechanism in the patent application number 202121395383.9 are as follows: 1. The displacement sensor is connected to the adjusting rod, and the magnetic base connecting rod and adjusting rod are relatively thin and long, resulting in poor stability. It is easy to fall over due to accidental contact, causing personal injury or damage to the displacement sensor; 2. The magnetic base is connected to the floor, and the magnetic base connecting rod and adjusting rod are relatively long, providing a large force for the magnetic base to tip over; the contact area between the magnetic base and the floor is small, and the floor is not clean; making the magnetic base easy to tip over when subjected to external forces. Utility Model Content

[0005] The main purpose of this utility model is to provide a vehicle body and frame stiffness measuring device to solve the problems of poor stability of the magnetic seat connecting rod and adjusting rod in the prior art, which are prone to falling over when accidentally bumped, and the magnetic seat is prone to tipping over when subjected to external force.

[0006] To achieve the above objectives, this utility model provides a vehicle body and frame stiffness measuring device, including a T-slot platform, a lifting rod fixedly connected to the T-slot platform by T-bolts and nuts; a magnetic base fixedly connected to the top of the lifting rod, an adjusting rod connected to the magnetic base, and a displacement sensor fixedly connected to the adjusting rod.

[0007] Furthermore, the lifting rod includes a base plate with bolt holes for engaging with T-bolts; a slide cylinder is fixedly connected to the top of the base plate, and a slide rod is slidably connected inside the slide cylinder; a locking bolt is threadedly connected to the side of the slide cylinder, and a support plate is fixedly connected to the top of the slide rod.

[0008] Furthermore, the bolt holes are located at the center of the base plate, and the center line of the slide rod passes through the center of the base plate; the base plate is fixedly connected to the slide cylinder through a portal frame.

[0009] Furthermore, the magnetic base is connected to the adjusting rod via a connecting clip; the connecting clip includes a rotating shaft fixedly connected to the magnetic base, a connecting block movably connected to the rotating shaft, and a locking knob threadedly connected to the rotating shaft for locking the connecting block; the adjusting rod is fixedly connected to the connecting block.

[0011] Furthermore, the lengths of the first and second poles are 15-20cm.

[0012] This invention uses a small magnetic base and adjusting rod in conjunction with a relatively long lifting rod. The magnetic base and adjusting rod are located above the lifting rod, making them less prone to accidental contact. The adjusting rod is also shorter, resulting in greater stability. The magnetic base is fixed to the top of the adjusting rod, which allows for greater cleanliness of the top of the adjusting rod. The shorter length of the adjusting rod also minimizes the lateral force exerted on the magnetic base, further enhancing the stability of the magnetic base connection and reducing the risk of equipment damage and personal injury.

[0021] The lifting rod 1 includes a base plate 101, which has bolt holes 106 that mate with T-bolts 2; a slide cylinder 102 is fixedly connected to the top of the base plate 101, and a slide rod 103 is slidably connected inside the slide cylinder 102; a locking bolt 104 for locking the slide rod 103 is threadedly connected to the side of the slide cylinder 102, and a support plate 105 is fixedly connected to the top of the slide rod 103.

[0022] Bolt hole 106 is located at the center of base plate 101, and center line of slide rod 103 passes through the center of base plate 101; base plate 101 is fixedly connected to slide cylinder 102 through portal frame 107; bolt hole 106 is located at the center of base plate 101, making the connection to base plate 101 more stable; by setting portal frame 107, space is left for wrench to tighten nut 4.

[0023] The magnetic base 5 is connected to the adjusting rod 6 via a connecting clip 8. The connecting clip 8 includes a rotating shaft 801 fixedly connected to the magnetic base 5, a connecting block 802 movably connected to the rotating shaft 801, and a locking knob 803 threadedly connected to the rotating shaft 801 for locking the connecting block 802. The adjusting rod 6 is fixedly connected to the connecting block 802. Loosening the locking knob 803 allows the adjusting rod 6 to rotate around the rotating shaft 801. Tightening the locking knob 803 fixes the adjusting rod 6 in place.

[0024] The adjusting rod 6 includes a first rod 601 fixedly connected to a connecting block 802, and a second rod 602 connected to the first rod 601 via a connecting clip 603.

Tightening the knob 603d fixes the second rod 602 in place.

[0025] The lengths of the first rod 601 and the second rod 602 are 15-20cm.

[0026] When using the vehicle body and frame stiffness measuring device, first adjust the height of the lifting rod 1; then adjust the angle of the first rod 601 in the front-rear direction and the angle of the second rod 602 in the left-right direction by connecting clamp 1 8 and connecting clamp 2 603 to fine-tune the position of the displacement sensor 7; finally, use the displacement sensor 7 to perform the measurement.

[0027] This embodiment uses a small magnetic base and adjusting rod in conjunction with a relatively long lifting rod.
