Description

Technical Field

[0001] This utility model is applicable to the field of automobile manufacturing, and in particular relates to an automobile lifting device. Background Technology

[0002] Automotive lifting devices typically consist of a support base, a column, and a lifting drive mechanism (such as a hydraulic cylinder or electric lead screw). Driven by a power source, they lift the car to a suitable height for maintenance, assembly, and other operations. Some models are also equipped with safety locks and limit switches.

[0003] Existing automotive machining lifting devices typically support the vehicle directly at the center of the underside, resulting in poor force uniformity and reduced vehicle stability during lifting, which is detrimental to precise machining. Furthermore, because this support method places the force directly on the underside of the vehicle, it can sometimes damage the underbody structure. In addition, existing automotive machining lifting devices have limited application scenarios and functions, failing to meet diverse lifting needs such as unilateral lifting.

[0004] In summary, the problems existing in the relevant technologies urgently need to be solved. Utility Model Content

[0028] in, Figure 1 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 1 The embodiments of this utility model will be described in the directions shown.

[0029] See Figure 1 , Figure 2 , Figure 3 This utility model provides a car lifting device, including a first lifting mechanism 100 and a second lifting mechanism 200. The output end of the first lifting mechanism 100 is provided with a first car carrier plate 300, and the output end of the second lifting mechanism 200 is provided with a second car carrier plate 400. The first lifting mechanism 100 and the second lifting mechanism 200 can perform driving actions synchronously, asynchronously, or only one of them can perform driving actions. The first car carrier plate 300 and the second car carrier plate 400 both extend a certain length in the front-rear direction and are spaced apart from each other. The first car carrier plate 300 and the second car carrier plate 400 are provided with front wheel positioning slots 301 and 401 at corresponding positions, and the first car carrier plate 300 and the second car carrier plate 400 are provided with rear wheel positioning slots 302 and 402 at corresponding positions. The first vehicle-carrying plate 300 and the second vehicle-carrying plate 400 can position the car that has driven to the top of the vehicle-carrying plate through four positioning slots, thereby further lifting the car through the first lifting mechanism 100 and the second lifting mechanism 200. In other words, this car lifting device achieves the lifting of the vehicle by directly supporting the wheels.

[0030] Combination Figures 1-3In this invention, a vehicle carrier plate is installed at the output end of the lifting mechanism. The vehicle carrier plate has front wheel positioning slots 301 and 401 and rear wheel positioning slots 302 and 402. During use, the car can drive directly onto the vehicle carrier plate, allowing the wheels to enter the corresponding positioning slots, thus positioning the tires and preventing displacement during lifting. The lifting mechanism then lifts the car. This invention directly supports the wheels via the vehicle carrier plate, better bearing the car's weight, improving stability, reducing the risk of uneven load, and facilitating precise machining. Furthermore, because the force is applied directly to the wheels, damage to the car's underbody structure is effectively avoided. In addition, this invention allows for unilateral lifting, making its application scenarios and functions more diverse.

[0031] The front wheel positioning slots 301 and 401 and the rear wheel positioning slots 302 and 402 of the first vehicle carrier plate 300 and the second vehicle carrier plate 400 can be formed by creating grooves, pits or through holes on the vehicle carrier plate. When the tires of the car drive into the positioning slots, the tires will sink into the corresponding positioning slots to achieve the positioning function, so that the car is stopped in a suitable position, so that the lifting device can accurately lift the car.

[0032] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The top surface of the first vehicle carrier plate 300 is provided with a first anti-slip structure 303. The first anti-slip structure 303 can be formed by means of rubber pads or grooves to ensure that the car can drive into or out of the positioning slot normally and smoothly.

[0033] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The top surface of the second vehicle carrier plate 400 is provided with a second anti-slip structure 403. The second anti-slip structure 403 can be formed by means of rubber pads or grooves to ensure that the car can drive into or out of the positioning slot normally and smoothly.

[0034] In some embodiments, see Figure 1 , Figure 2 , Figure 3 Both the first vehicle platform 300 and the second vehicle platform 400 are equipped with vehicle entry ramps 304 and 404 at their front entrances, through which vehicles drive onto the vehicle platforms.

[0035] In some embodiments, see Figure 1 , Figure 2 , Figure 3The rear ends of the first vehicle platform 300 and the second vehicle platform 400 are each provided with blocking members 305 and 405. The blocking members 305 and 405 can limit the vehicle and prevent the vehicle from driving out from the rear ends of the first vehicle platform 300 and the second vehicle platform 400, so that the vehicle stops in a suitable position.

[0036] In some embodiments, see Figure 4 Both the first lifting mechanism 100 and the second lifting mechanism 200 include a driving member 101, a lifting guide structure, and a lifting component 102. The lifting guide structure extends along the height direction, and the lifting component 102 is movably mounted on the lifting guide structure. The lifting component 102 is connected to the output end of the driving member 101. The lifting component 102 of the first lifting mechanism 100 has a first lifting arm extending to the bottom of the first vehicle platform 300, and the lifting component 102 of the second lifting mechanism 200 has a second lifting arm extending to the bottom of the second vehicle platform 400. The lifting guide structure cooperates with the lifting component 102 to achieve lifting guidance while also preventing the transmission of the overturning moment of the vehicle platform to the driving member 101, thereby extending the service life of the entire device.

[0037] Further, see Figure 1 , Figure 2 , Figure 4 Both the first lifting arm and the second lifting arm include a first support arm 103 and a second support arm 104. The first support arm 103 and the second support arm 104 of the first lifting arm are V-shaped and support the bottom of the first vehicle platform 300. The first support arm 103 and the second support arm 104 of the second lifting arm are V-shaped and support the bottom of the second vehicle platform 400. In this embodiment, the first lifting arm and the second lifting arm adopt a V-shaped design, forming multi-point support along the length of the vehicle platform, thereby improving the stability of the entire device.

[0038] The lifting guide structure can adopt guide rails, guide grooves, etc., as shown in some embodiments. Figure 4 The lifting guide structure includes a guide rod 105, and the lifting component 102 is provided with a guide hole fitted onto the guide rod 105. The driving component 101 includes a hydraulic cylinder, which is connected to a hydraulic pump 106. The output end of the hydraulic cylinder is connected to the lifting component 102 via a connecting rod. During operation, the hydraulic pump 106 serves as the power source. When the hydraulic pump 106 is started, it delivers hydraulic oil to the hydraulic cylinder. The hydraulic oil transmits pressure in the closed hydraulic system, causing the hydraulic cylinder to perform lifting and lowering movements. When the hydraulic cylinder rises, it drives the connecting rod to rise, and the connecting rod drives the lifting arm to rise, thereby realizing the lifting function of the car. During the lifting and lowering process of the lifting arm, the lifting component 102 is always in contact with the guide rod 105, restricting the lifting component 102 to move only in a predetermined vertical direction.

[0039] In some embodiments, the first lifting mechanism 100 and the second lifting mechanism 200 are provided with a protective shell 501 and a diagonal brace 502 on their outer sides, and a control panel 503 is fixedly connected to the middle of the front end of the protective shell 501. The first lifting mechanism 100 and the second lifting mechanism 200 are reinforced by the diagonal braces 502 on both sides, and this symmetrical structure makes the lifting process more stable.

[0040] In some embodiments, the first lifting mechanism 100 and the second lifting mechanism 200 are disposed on the base 600, and the distance between the first lifting mechanism 100 and the second lifting mechanism 200 on the base is adjustable. This allows for adaptive adjustment according to different vehicle widths.
