Description

Technical Field

[0001] The present invention relates to the technical field of motor vehicle inspection and maintenance, and more specifically, to a motor vehicle inspection and maintenance device and a use system thereof. Background Art

[0002] In the process of motor vehicle maintenance and inspection, the motor vehicle chassis dynamometer, a precision indoor device also known as the "drum test bench", plays an indispensable role. It can comprehensively and deeply measure the performance indicators of motor vehicles, accurately evaluate their technical conditions, and effectively diagnose potential faults by subtly simulating the various resistances encountered by motor vehicles when driving on real roads. What is particularly critical is that the equipment focuses on capturing core data such as the output power, torque and speed of the drive wheels, while quickly and accurately revealing the working efficiency of various systems and components of the motor vehicle, providing a solid basis for maintenance decisions.

[0003] It is worth noting that the chassis dynamometer of motor vehicles is usually cleverly embedded underground. The vehicle only needs to drive over it easily to activate the detection mechanism through the close interaction between the tire and the drum, thereby achieving non-contact detection of the entire vehicle. This design not only simplifies the operation process, but also greatly improves the detection efficiency. As the primary link in the maintenance and inspection process, the comprehensive scanning of the chassis dynamometer can quickly identify the technical status of the vehicle and the source of the fault, and point out the direction for subsequent maintenance work.

[0004] However, the traditional detection method requires the front wheel or rear wheel of the vehicle to be accurately placed on the chassis dynamometer, and the other wheel to be manually fixed with a block. This is not only cumbersome to operate, but also prone to errors due to human factors. In addition, the risk of lateral movement of the unfixed wheel and the inconvenience of setting the block restrict the detection efficiency and accuracy to a certain extent. In view of this, we propose a motor vehicle detection and maintenance device and its use system. Summary of the invention

[0022] A system for using a motor vehicle inspection and maintenance device comprises the following steps:

[0023] The control system can operate after the vehicle is above the detection device, and adjust the height of the lifter to make the tire contact with the detection device. When the lifter is running, it will squeeze the gas in the pressure component into the pressure sensor, causing the internal pressure of the pressure sensor to increase. At this time, the pressure sensor will trigger the electric push rod to push the anti-skid component up, and then the detection device is started through the control system to detect the vehicle. After the detection is completed, the detection device is closed by the control system and the height of the push component is adjusted to drive the vehicle out.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention designs a pressure component, an electric push rod and an anti-skid mechanism. When the push block descends and pushes the push rod downward, the push rod will squeeze the gas in the sealing cylinder along the docking port into the conduit and the docking tube by squeezing the piston plate downward. When the gas enters the docking tube, the docking tube will discharge the gas into a plurality of pressure sensors, causing the air pressure in the pressure sensors to change. At this time, the pressure sensor will send a signal and start the electric push rod, and the anti-slip block will be pushed out by moving the electric push rod upward, so that the anti-skid groove on the surface of the anti-slip block contacts the wheel that has not been detected by the detection device, thereby completing the fixation of the wheel. When the device detects the vehicle, it only needs to start the lifter to move the push block downward to synchronously complete the fixation of the undetected tire, so that the device does not need to move the anti-slip block manually, thereby improving the automation degree of the device and reducing the difficulty of using the device.

[0026] 2. The present invention also designs a detection mechanism. When the push block moves downward due to the adjustment of the lifter, the lifter will push the first tooth plate to move downward. Since the first tooth plate is meshed with the gear, when the first tooth plate moves downward, the gear will rotate and drive the second tooth plate meshed with it to move. Since the second tooth plate is connected to the limit slider through the positioning rod and the support frame, the limit sliders on both sides will synchronously drive the fixed block and the pulley to move toward each other when moving, so that the fixed blocks and the pulleys on both sides are clamped on both sides of the wheel, ensuring that the device can limit the position of the vehicle during the process of detecting the vehicle, avoiding the situation where the vehicle moves laterally during detection and separates from the detection device. On the one hand, it ensures the accuracy of the detection data, and on the other hand, it improves the safety of the device during detection.

[0027] 3. The present invention also designs a lifter and a pressure sensor. After the detection is completed, the lifter is used to push the push block upward to disengage the wheel from the detection device. At this time, the fixed blocks and pulleys on both sides will be reset synchronously due to the reset of the first tooth plate. At the same time, the piston plate will also extract the gas in the pressure sensor through the conduit and the connecting pipe, thereby closing the signal transmitting the electric push rod, and then restoring the electric push rod. The device only needs to control the detection device and the lifter to complete the detection of the vehicle and the restoration of the device, thereby reducing the difficulty of using the device.

By designing the detection mechanism 2, when the push block 205-1 is adjusted by the lifter 208 and moves downward, the lifter 208 moves upward. The descender 208 will push the first tooth plate 207-4 to move downward. Since the first tooth plate 207-4 is meshed with the gear 207-3, when the first tooth plate 207-4 moves downward, the gear 207-3 will rotate and drive the second tooth plate 207-5 meshed with it to move. Since the second tooth plate 207-5 is connected to the limit slider 204-1 through the positioning rod 207-6 and the support frame 207-7, the limit sliders 204-1 on both sides will synchronously drive the fixed blocks 204-2 and the pulley 204-3 to move toward each other when moving, so that the fixed blocks 204-2 and the pulley 204-3 on both sides are clamped on both sides of the wheel, ensuring that the device can limit the position of the vehicle during the process of detecting the vehicle, avoiding the situation where the vehicle moves laterally during the detection and separates from the detection device 202. On the one hand, it ensures the accuracy of the detection data, and on the other hand, it improves the safety of the device during detection.

The pressure sensor 303 is electrically connected to the electric push rod 304 through a wire, the lower part of the plurality of anti-skid components 305 is fixedly connected to the top of the electric push rod 304, the lower end of the electric push rod 304 is fixedly connected to the lower part of the inner wall of the anti-skid shell 301, the other end of the butt pipe 302 is connected to the conduit 209, the control system 1 is electrically connected to the detection device 202 through a wire, and the lifter 208 and the pressure sensor 303 are designed. After the detection is completed, the lifter 208 is used to push the push block 205-1 upward to disengage the wheel. When the detection device 202 is separated, the fixed blocks 204-2 and the pulley 204-3 on both sides will be reset synchronously due to the reset of the first tooth plate 207-4. At the same time, the piston plate 206-3 will also extract the gas in the pressure sensor 303 through the conduit 209 and the connecting pipe, thereby closing the signal transmitting the electric push rod 304, and then restoring the electric push rod 304, so that the device only needs to control the detection device 202 and the lifter 208 to complete the detection of the vehicle and the restoration of the device, thereby reducing the difficulty of using the device.

[0048] In an embodiment of the present invention, the positioning component 204 includes a limit slider 204-1, the upper part of the limit slider 204-1 is fixedly connected to the lower part of the fixed block 204-2, one side of the fixed block 204-2 is fixedly connected to a plurality of pulleys 204-3, the fixed block 204-2 is arc-shaped, one side of the limit slider 204-1 is fixedly connected to two slide cylinders 204-4, and the two slide cylinders 204-4 are slidably connected with slide rods 204-5, the two ends of the slide rod 204-5 are respectively fixedly connected to the two sides of the inner wall of the mounting frame 204-6, the mounting frame 204-6 is fixedly connected to the upper part of the body shell 201, the limit slider 204-1 is slidably connected in the limit slide groove 203, the lower part of the limit slider 204-1 is tightly welded to the power component 207, and the push component 205 includes a push block 205-1, and a plurality of reinforcing ribs 205-2 are arranged inside the push block 205-1. The lower part of the push block 205-1 is tightly welded to the upper part of the two power components 207, and the lower part of the push block 205-1 is fixedly connected to the upper part of the pressure component 206. The lower part of the push block 205-1 is fixedly connected to the top of the lifter 208. When the first tooth plate 207-4 moves downward, the second tooth plate 207-5 slides with the rotation of the gear 207-3, and the second tooth plate 207-5 will enter between the two first tooth plates 207-4. Since the gap between the two first tooth plates 207-4 is greater than the width of the second tooth plate 207-5, the first tooth plate 207-4 will not affect the movement of the second tooth plate 207-5, thereby ensuring the stability of the device when in use.

[0049] As another embodiment of the present invention, the pressure assembly 206 includes a sealing cylinder 206-1, a push rod 206-2 is slidably connected inside the sealing cylinder 206-1, a piston plate 206-3 is fixedly connected to the bottom end of the push rod 206-2, the diameter of the piston plate 206-3 is matched with the diameter of the inner wall of the sealing cylinder 206-1, two docking ports 206-4 are opened outside the sealing cylinder 206-1, the sealing cylinder 206-1 is connected to the conduit 209 through the two docking ports 206-4, the bottom of the sealing cylinder 206-1 is tightly welded to the bottom of the inner wall of the body shell 201, the top of the push rod 206-2 is fixedly connected to the bottom of the push block 205-1, and the power assembly 207 includes a bearing 207-1, the number of the bearings 207-1 is two, and the same rotating shaft 207 is sleeved in the two bearings 207-1 -2, a gear 207-3 is fixedly connected to the outside of the rotating shaft 207-2, the gear 207-3 is meshed with the two first tooth plates 207-4, the gear 207-3 is meshed with the second tooth plate 207-5, the two first tooth plates 207-4 and the second tooth plate 207-5 are arranged at 90 degrees, the gap between the two first tooth plates 207-4 is larger than the width of the second tooth plate 207-5, one side of the second tooth plate 207-5 is fixedly connected to the positioning rod 207-6, the other end of the positioning rod 207-6 is fixedly connected to the support frame 207-7, by setting a fixed block 204-2, and the shape of the fixed block 204-2 is arc-shaped, so that when the device is in use, the arc-shaped setting of the fixed block 204-2 can better fit the two sides of the wheel, thereby avoiding the misalignment and lateral shift of the wheel when rotating;

[0050] By arranging a plurality of pulleys 204-3 outside the fixed block 204-2, when the fixed block 204-2 is in contact with the wheel, the pulley 204-3 will be in contact with the wheel, so that when the wheel rotates, the pulley 204-3 will rotate synchronously therewith, thereby converting the hard friction between the wheel and the fixed block 204-2 into rolling friction, thereby reducing the wear of the wheel and ensuring the accuracy of the detection data of the device.

[0051] As another embodiment of the present invention, the top of the support frame 207-7 is fixedly connected to the bottom of the limit slider 204-1, the tops of the two first tooth plates 207-4 are fixedly connected to the bottom of the same push block 205-1, and the two bearings 207-1 are respectively clamped on the front and back of the inner wall of the body shell 201. The anti-slip component 305 includes an anti-slip block 305-1, which is in the shape of a long strip, and an anti-slip block 305-1 is provided on the top. The slide groove 305-2 and the anti-sliding block 305-1 are fixedly connected with a pin shaft 305-3 below. The anti-sliding block 305-1 is arranged in the anti-sliding housing 301. The anti-sliding block 305-1 is hinged to the top of the electric push rod 304 through the pin shaft 305-3. By designing the pressure assembly 206, the electric push rod 304 and the anti-sliding mechanism 3, when the push block 205-1 descends and pushes the push rod 206-2 downward, the push rod 206-2 will squeeze the piston plate 206 -3 moves downward to squeeze the gas in the sealing cylinder 206-1 along the docking port 206-4 into the conduit 209 and the docking tube 302.

At this time, the pressure sensor 303 will send a signal and start the electric push rod 304, and the anti-slip block 305-1 will be pushed out by the upward movement of the electric push rod 304, so that the anti-skid groove 305-2 on the surface of the anti-slip block 305-1 contacts the wheel that is not detected by the detection device 202, thereby completing the fixation of the wheel, so that when the device detects the vehicle, it only needs to start the lifter 208 to move the push block 205-1 downward to synchronously complete the fixation of the undetected tire, so that the device does not need to manually move the anti-slip block 305-1, thereby improving the degree of automation of the device and reducing the difficulty of using the device.

[0052] A system for using a motor vehicle inspection and maintenance device comprises the following steps:

[0053] The control system 1 can be operated after the vehicle is above the detection device 202, and the height of the lifter 208 can be adjusted to make the tire contact with the detection device 202. When the lifter 208 is in operation, the gas in the pressure component 206 will be squeezed into the pressure sensor 303, so that the internal pressure of the pressure sensor 303 increases. At this time, the pressure sensor 303 will trigger the electric push rod 304 to push the anti-skid component 305 up, and then the detection device 202 is started through the control system 1 to detect the vehicle. After the detection is completed, the detection device 202 is closed by the control system 1 and the height of the pushing component 205 is adjusted to drive the vehicle out.

[0054] Working principle: This embodiment provides a motor vehicle inspection and maintenance device and its use system. When in use, the vehicle needs to be driven above the inspection device 202, and the lifter 208 is started by the control system 1, so that the lifter 208 drives the push block 205-1 to descend, and the wheel loses the support of the push block 205-1 and falls into the inspection device 202. At this time, the inspection device 202 can be started to inspect the vehicle;

[0055] When the push block 205-1 descends and pushes the push rod 206-2 downward, the push rod 206-2 will squeeze the gas in the sealing cylinder 206-1 along the docking port 206-4 into the conduit 209 and the docking tube 302 by squeezing the piston plate 206-3 downward. After the gas enters the docking tube 302, the docking tube 302 will discharge the gas into a plurality of pressure sensors 303, so that the air pressure in the pressure sensor 303 changes. At this time, the pressure sensor 303 will send a signal and start the electric push rod 304. The anti-slip block 305-1 is pushed out by the upward movement of the electric push rod 304, so that the anti-skid groove 305-2 on the surface of the anti-slip block 305-1 contacts the wheel that has not been detected by the detection device 202, thereby completing the fixation of the wheel.

[0056] When the push block 205-1 is adjusted and moves downward by the lifter 208, the lifter 208 will push the first tooth plate 207-4 to move downward. Since the first tooth plate 207-4 is meshed with the gear 207-3, when the first tooth plate 207-4 moves downward, the gear 207-3 will rotate and drive the second tooth plate 207-5 meshed therewith to move. Since the second tooth plate 207-5 is connected to the limit slider 204-1 through the positioning rod 207-6 and the support frame 207-7, the limit sliders 204-1 on both sides will synchronously drive the fixed block 204-2 and the pulley 204-3 to move toward each other when moving, so that the fixed blocks 204-2 and the pulley 204-3 on both sides are clamped on both sides of the wheel;

[0057] After the detection is completed, it is necessary to push the push block 205-1 upward through the lifter 208 to disengage the wheel from the detection device 202. At this time, the fixed blocks 204-2 and the pulley 204-3 on both sides will be reset synchronously due to the reset of the first tooth plate 207-4. At the same time, the piston plate 206-3 will also extract the gas in the pressure sensor 303 through the conduit 209 and the connecting pipe, thereby closing the signal transmitting the electric push rod 304, and then restoring the electric push rod 304.

[0058] In the present application, the circuit operation is an existing conventional circuit, and the circuits and controls involved in the present invention are all existing technologies, which will not be described in detail here.

[0059] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
