Description

Technical Field

[0001] This utility model relates to the field of anti-tipping technology for van centers of gravity, specifically an anti-tipping device for van centers of gravity. Background Technology

[0002] Box trucks, also known as vans, are mainly used for fully enclosed transportation of various goods. Special types of box trucks can also transport hazardous chemicals. Due to their high body and high center of gravity, box trucks are easily affected by lateral forces during driving, especially when turning or making emergency obstacle avoidance, which can easily lead to rollover accidents. Anti-rollover devices can effectively prevent and reduce this risk.

[0003] Current anti-rollover devices for vans have poor adjustability during use, resulting in poor anti-rollover performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a center of gravity anti-tipping device for vans, thereby solving the problem mentioned in the background art that current center of gravity anti-tipping devices for vans have poor adjustability during use, resulting in poor anti-tipping effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a center of gravity anti-tipping device for a van, comprising a base, a support frame fixedly installed on the outer surface of the base, a displacement sensor embedded in the outer surface of the base, two servo motors embedded in the outer surface of the base away from the displacement sensor, worm gears fixedly installed at the output ends of the two servo motors, a support fixedly installed on the outer surface of the base, several worm wheels meshing with the outer surfaces of the two worm gears, several worm wheels rotatably connected to the support, screws fixedly installed on the outer surfaces of the several worm wheels, several limiting grooves formed on the outer surface of the base, and counterweights slidably connected to the outer surfaces of the several screws through the limiting grooves.

[0006] Preferably, four electrically telescopic support columns are embedded and connected to the outer surface of the base. Each of the four electrically telescopic support columns has a fixed base at its output end. A connector is fixedly installed on the outer surface of the fixed base, and a mounting seat is provided on the outer surface of the connector.

[0007] Preferably, the screws are arranged at a 90-degree angle to the worm gear, and the screws are evenly arranged on both sides of the base.

[0008] Preferably, the displacement sensor is electrically connected to the servo motor and the electric telescopic support, and the outer surface of the base is fixedly equipped with wind-resistant and anti-slip components.

[0009] Preferably, the base is rectangular, and the four electrically telescopic support columns are located at the chamfered corners of the base, and each of the four electrically telescopic support columns is equipped with a self-locking valve.

[0010] Preferably, the output end of the displacement sensor is provided with a safety threshold model, and the outer surface of the support frame is in close contact with the outer surface of the mounting base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This anti-tipping device for vans uses a support frame to protect the counterweight block on the outer surface of the base, preventing the counterweight block from being difficult to move. A position sensor detects the horizontal center of gravity of the van during operation. When the van tilts, the servo motor drives the worm gear and worm wheel to mesh and rotate, causing the screw to rotate. This causes the counterweight block to slide horizontally along the outer surface of the screw under the restriction of the limit groove, thereby reducing the poor adjustability of the anti-tipping device and the resulting poor anti-tipping effect.

[0013] 2. The anti-tipping device for this van automatically adjusts the support strength of four electric telescopic pillars according to the vehicle's tilt angle, and the connecting parts self-adjust the support angle to disperse the lateral tilting torque. This adjusts the tilt angle between the mounting base and the ground, thereby improving the adjustment accuracy and making the vehicle more stable during operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please refer to Figures 1-4.

[0022] A center of gravity anti-tipping device for a van includes a base 1, a support frame 4 fixedly installed on the outer surface of the base 1, a displacement sensor 5 embedded in the outer surface of the base 1, two servo motors embedded in the outer surface of the base 1 away from the displacement sensor 5, worm gears 6 fixedly installed at the output ends of the two servo motors, a support 7 fixedly installed on the outer surface of the base 1, several worm wheels 8 meshing with the outer surfaces of the two worm gears 6, several worm wheels 8 rotatably connected to the support 7, screws 9 fixedly installed on the outer surfaces of the several worm wheels 8, several limiting grooves 10 formed on the outer surface of the base 1, and counterweights 11 slidably connected to the outer surfaces of the several screws 9 through the limiting grooves 10.

[0023] Specifically, the counterweight 11 on the outer surface of the base 1 is protected by the support frame 4 to prevent the counterweight 11 from being difficult to move. The position sensor detects the center of gravity level of the van in operation. When the van tilts, the servo motor drives the worm gear 6 to mesh with the worm wheel 8, causing the screw 9 to rotate. This causes the counterweight 11 to slide horizontally along the outer surface of the screw 9 under the restriction of the limit groove 10, thereby reducing the center of gravity. The poor adjustability of the anti-tipping device leads to a poor anti-tipping effect.

[0024] In the embodiment: several screws 9 are all set at an angle of 90 degrees to the worm gear 6, and several screws 9 are evenly arranged on both sides of the base 1.

[0025] Specifically, because several screws 9 are set at a 90-degree angle to the worm gear 6, and several screws 9 are evenly arranged on both sides of the base 1, the counterweight position is adjusted in real time through horizontal displacement to ensure the stability of the vehicle's center of gravity under different load conditions. This, combined with the displacement sensor 5, achieves closed-loop control and improves adjustment accuracy.

[0026] In this embodiment: the output end of the displacement sensor 5 is provided with a safety threshold model, and the outer surface of the support frame 4 is in close contact with the outer surface of the mounting base 3.

[0027] Specifically, a safety threshold model is set at the output end of the displacement sensor 5. When the vehicle body tilt angle exceeds the preset range or the tire load is abnormal, an early warning is triggered. At the same time, the outer surface of the support frame 4 is attached to the outer surface of the mounting seat 3 to make it more firmly supported.

[0028] Working principle: A support frame 4 is fixedly installed on the outer surface of the base 1. A displacement sensor 5 is embedded in the outer surface of the base 1. Simultaneously, two servo motors are embedded in the outer surface of the base 1 away from the displacement sensor 5. Worm gears 6 are fixedly installed at the output ends of both servo motors. A support 7 is fixedly installed on the outer surface of the base 1. Several worm wheels 8 are meshed with the outer surfaces of the two worm gears 6, and these worm wheels 8 are rotatably connected to the support 7. Screws 9 are fixedly installed on the outer surfaces of the worm wheels 8. Furthermore, several limiting grooves 10 are formed on the outer surface of the base 1, and the outer surfaces of the screws 9 are slidably connected through these limiting grooves 10. The counterweight 11 and the support frame 4 protect the counterweight 11 set on the outer surface of the base 1 to prevent the counterweight 11 from being difficult to move. The position sensor detects the center of gravity level of the van in operation. When the van tilts, the servo motor drives the worm gear 6 to mesh and rotate with the worm wheel 8, so that the screw 9 rotates and drives the counterweight 11 to slide horizontally along the outer surface of the screw 9 under the restriction of the limit groove 10. Compared with related technologies, the anti-tipping device for the center of gravity of the van provided by this utility model has the following beneficial effects: it reduces the poor adjustability of the anti-tipping device, which leads to poor anti-tipping effect.

[0029] Example 2:

[0030] Please refer to Figures 1-4.

[0031] Four electric telescopic support columns 12 are embedded and connected to the outer surface of the base 1. The output ends of the four electric telescopic support columns 12 are all fixedly installed with a fixed seat 13. A connector 2 is fixedly installed on the outer surface of the fixed seat 13. A mounting seat 3 is provided on the outer surface of the connector 2.

[0032] Specifically, by controlling the four electric telescopic struts 12 to automatically adjust the support force according to the vehicle's tilt angle, the connector 2 self-adjusts the support angle, disperses the lateral tilting torque, and drives the mounting base 3 to adjust the tilt angle with the ground, thereby improving the adjustment accuracy and making it more stable during operation.

[0033] In this embodiment: the displacement sensor 5 is electrically connected to the servo motor and the electric telescopic support column 12, and the outer surface of the base 1 is fixedly equipped with wind-resistant and anti-slip components.

[0034] Specifically, since the displacement sensor 5 is electrically connected to the servo motor and the electric telescopic support 12, it collects the vehicle's center of gravity offset and tire load data in real time, and adjusts the electric telescopic support 12 to support and stabilize the vehicle's center of gravity. Wind-resistant and anti-slip components are fixedly installed on the outer surface of the base 1, and an integrated electromagnetic rail clamp can be set on the chassis. In strong wind environments, it can adhere to specific tracks or ground anchor points to improve lateral stability.

[0035] In the embodiment: the base 1 is rectangular, and four electric telescopic support columns 12 are arranged at the chamfer of the base 1, and each of the four electric telescopic support columns 12 is equipped with a self-locking valve.

[0036] Specifically, because the base 1 is rectangular and the four electric telescopic pillars 12 are located at the chamfer of the base 1, the support force is automatically adjusted according to the vehicle tilt angle to form a rigid auxiliary support. In addition, each of the four electric telescopic pillars 12 is equipped with a self-locking valve, so that the electric telescopic pillars 12 automatically maintain the current support state when the power is cut off or the hydraulic system fails.

[0037] Working principle: Four electric telescopic support columns 12 are embedded and connected to the outer surface of the base 1. At the same time, the output ends of the four electric telescopic support columns 12 are fixedly installed with fixed seats 13. Connecting parts 2 are fixedly installed on the outer surface of the fixed seats 13. Mounting seats 3 are provided on the outer surface of the connecting parts 2. The four electric telescopic support columns 12 are controlled to automatically adjust the support force according to the vehicle tilt angle. The connecting parts 2 self-adjust the support angle, disperse the lateral tilting torque, and drive the mounting seats 3 to adjust the tilt angle with the ground. Compared with related technologies, the anti-tipping device for the center of gravity of a van provided by this utility model has the following beneficial effects: thereby improving the adjustment accuracy and making it more stable during operation.
