Abstract
Description
Technical Field
[0001] This utility model relates to automobile lift technology, and in particular to an automobile lift pad block. Background Technology
[0002] A car lift typically consists of two vertically fixed columns, each extending two lifting arms in a V-shape. A lifting tray is attached to the end of each lifting arm. The lifting arms are extendable, retractable, and rotatable around the columns, and the height of the lifting tray is also adjustable (see appendix). Figure 1 In the diagram, a is the lifting arm and b is the lifting tray.
[0003] The standard operating procedure for lifting a car is as follows:
[0004] 1. Crouch down to lower the height of the lift tray. This will prevent it from damaging the door sill trim when entering under the vehicle.
[0005] 2. Move the lifting arm under the car and raise the height of the lifting tray. This is to prevent the lifting arm from damaging the door sill trim during lifting if the upper surface of the lifting tray is too low.
[0006] 3. Turn to the side and look down to observe the relative position between the lifting tray and the vehicle's lifting point. Manually adjust the lifting arm multiple times to align the geometric center of the lifting tray with the vehicle's lifting point.
[0007] 4. Repeat the above steps to move the four lifting arms under the car and align them. Briefly start the lift, pausing just before the lifting arms lift the car and the tires are off the ground; turn sideways and look down to observe whether the four lifting trays are accurately and stably positioned at the lifting points, and whether the lifting arms are pressing on the exterior trim panels. Fully raise the lift and begin the operation.
[0008] Clearly, aligning the geometric center of the lift tray with the door sill lifting point is crucial, as it affects the stability of the car's center of gravity after lifting and prevents damage to the door sill trim and other underbody protection. Because of the poor lighting under the car, ensuring this alignment requires the operator to repeatedly bend over and observe, making the process complex and physically demanding.
[0009] It is evident that existing methods for aligning the lifting tray of a car lift have problems such as difficulty in aligning the geometric center of the lifting tray with the lifting point of the car door sill, resulting in high labor intensity and wasted time and effort. Summary of the Invention
[0010] To address the problems of difficulty in aligning the geometric center of the lifting tray with the car door sill in existing car lift alignment methods, which result in high labor intensity and time-consuming processes, this utility model proposes a car lift pad.
[0011] This utility model relates to a car lift pad, comprising: a body, a lighting lamp, a permanent magnet, a dot laser spotlight, a power switch, and a cover plate; the body is a rigid cubic structure, and there are four of them, each placed at the lifting point of the car sill; a groove is provided at the center line of the upper surface of the body to restrain the lateral movement of the pad and to avoid the longitudinal beam of the car sill, and cavities for accommodating the permanent magnet are provided on both sides of the groove, and a lighting lamp is provided at the bottom of the groove; a concave step is provided in the middle of the bottom surface of the body, and a red dot laser spotlight is provided at the geometric center of the concave step, a power switch is provided in front of the dot laser spotlight, and a battery compartment is provided behind the dot laser spotlight; the surface of the permanent magnet cavity is covered with a non-magnetic stainless steel cover plate; the surface of the battery compartment is covered with a cover plate.
[0012] Furthermore, the body is a high-strength aluminum alloy rigid cube.
[0013] Furthermore, the surface of the non-magnetic stainless steel cover plate is mirror-finished.
[0014] Furthermore, rubber pads are fixedly provided on the surfaces of the protrusions on both sides of the concave step at the bottom, or the surfaces are machined into a knurled surface structure.
[0015] The beneficial technical effect of this utility model of car lift pad is that it can accurately and conveniently align the geometric center of the lift tray with the car door sill lifting point, which is simple to operate and also reduces labor intensity. Attached Figure Description

[0017] Appendix Figure 2 This is a three-dimensional schematic diagram of the car lift pad block of this utility model; in the figure, 1 is the body, 2 is the slot, 3 is the lighting lamp, 4 is the permanent magnet, and 5 is the non-magnetic stainless steel cover plate.
[0018] Appendix Figure 3 This is a three-dimensional schematic diagram of the car lift pad block of this utility model from another angle; in the figure, 6 is a dot laser spotlight, 7 is a power switch, and 8 is a cover plate.
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation
[0020] See appendix Figure 2 , 3This utility model relates to a car lift pad, comprising: a body 1, a lighting lamp 3, a permanent magnet 4, a dot laser spotlight 6, a power switch 7, and a cover plate 8; the body is a rigid cubic structure and consists of four pieces, each placed at the lifting point of the car sill; a groove 2 is provided at the center line of the upper surface of the body to constrain the lateral movement of the pad and to avoid the longitudinal beam of the car sill, and cavities for accommodating the permanent magnet 4 are provided on both sides of the groove, with the lighting lamp 3 provided at the bottom of the groove; a concave step is provided in the middle of the bottom surface of the body, and a red dot laser spotlight 6 is provided at the geometric center of the concave step, with the power switch 7 provided in front of the dot laser spotlight and a battery compartment provided behind the dot laser spotlight; the surface of the permanent magnet cavity is covered with a non-magnetic stainless steel cover plate 5; and the surface of the battery compartment is covered with a cover plate 8.
[0021] The specific operating steps are as follows:
[0022] 1. Turn on the power supply to the car lift pad block of this utility model and observe whether the lighting and dot laser spotlight are normal;
[0023] 2. Crouch down and place the pad with the light facing upwards at the car door sill lift point. The light will increase the brightness of the bottom of the car body, and the reflective surface will allow for a clear view of the bottom of the car. Align the slot with the lift point of the door sill beam, so that the door sill beam is placed in the slot. Due to the attraction of the permanent magnet to the car body, the pad will be attracted to the lift point of the car door sill.
[0024] 3. Move the lifting arm under the vehicle and adjust it so that the dot-matrix laser spotlights on the bottom surface of the pad are positioned at the geometric center of the lifting tray. This aligns the geometric center of the lifting tray with the vehicle's lifting point. Since the height of the adapter block does not need to be lowered before raising the lifting tray, the lifting arm will not touch the door sill trim.
[0025] 4. Repeat the above steps until all four lifting arms are moved to the vehicle's lifting position. Turn on the car lift to raise the vehicle to the set height and begin work. After the work is completed, lower the vehicle, remove the lifting arms, and take out all the padding blocks.
[0026] As can be seen, with this utility model of car lift pad, the operator only needs to squat down to place the pad once and does not need to turn to the side and bend down to check the bottom of the car multiple times to align the geometric center of the lifting tray with the lifting point of the car door sill. The operation is simple and reduces labor intensity.
[0027] To minimize the weight of the pad body and reduce the operator's workload, as a preferred technical solution, the body is a high-strength aluminum alloy rigid cube. This allows for a reduction in the weight of the pad body while maintaining its rigidity and strength.
[0028] To facilitate observation of the car door sill lift point's position, as a preferred technical solution, the surface of the non-magnetic stainless steel cover is mirror-like. This allows the operator to observe the car door sill lift point through the mirror-like surface of the stainless steel cover, reducing the degree of bending and strenuous work for the operator.
[0029] To increase the friction between the surface of the lifting tray and the bottom surface of the pad body, as a preferred technical solution, rubber pads are fixedly installed on the surfaces of the protrusions on both sides of the concave step on the bottom surface, or the surface is machined into a knurled structure. This ensures that the car will not slip when lifted, preventing accidents. At the same time, the concave steps prevent the lifting tray from damaging lower switches, spotlights, and other accessories.
[0030] Obviously, the beneficial technical effect of this utility model of car lift pad is that it can accurately and conveniently align the geometric center of the lift tray with the car door sill lifting point, simplifying operation and reducing labor intensity.
