[0026] Such as figure 1 and figure 2 As shown, the vehicle-mounted electric elevator of the present embodiment includes a frame 10, and the frame 10 includes a first platform 11 and a second platform 12, and the first platform 11 and the second platform 12 are arranged in parallel, and the first platform 11 and the second platform 12 pass through the column The body 13 is connected, and the column body 13 can be a common mechanical connection part to fix the first platform 11 and the second platform 12 . Optionally, the frame 10 is made of high strength aluminum material.

[0027] A first motor 20 is arranged on the first platform 11, and the motor 20 can rotate in two directions. spinning speed. The rotating shaft on the first motor 20 drives the first bevel gear 30 to rotate, and the first bevel gear 30 meshes with the second bevel gear 31 , and when the first bevel gear 30 rotates, it drives the second bevel gear 31 to rotate.

[0034] This embodiment is another vehicle-mounted electric lift, and the same parts of the lift in this embodiment and the lift in the first embodiment will not be repeated here.

[0035] Such as Figure 4 and Figure 5 As shown, the vehicle-mounted electric lift in this embodiment has a frame 100, and the frame 100 includes a first platform 110 and a second platform 120, each platform can be connected by a column, and the second platform 120 is connected with a third platform 130. In addition, a fourth platform 140 is also provided on the frame 100, and three second driven wheels 400 are arranged on the fourth platform 140, and the second driven wheels 400 are supported on the fourth platform 140 through bearings, and the second driven wheels 400 can rotate to rotate. The center of the second driven wheel 400 is provided with a second opening, and the second opening is provided with internal threads along the axial direction. A second screw rod 500 is disposed through the ...

[0040] For cars whose chassis height is less than 15 centimeters, such as Figure 6 As shown, on the basis of the second embodiment, this embodiment needs to be used in conjunction with an auxiliary mechanism. The auxiliary mechanism is a trapezoidal structure 600 , and the trapezoidal structure 600 includes an upper bottom surface 601 and a side surface 602 . When the car needs to change tires, the driver controls the car to run slowly, and moves a vehicle-mounted tire to the upper bottom surface 601 along the side 602. At this time, the height of the vehicle-mounted chassis from the ground increases. Through the vehicle-mounted electric lift of the first embodiment or the second embodiment, the vehicle-mounted chassis can be lifted, and such an embodiment significantly expands the application range of the vehicle-mounted electric lift of this embodiment.

Abstract

The invention provides a vehicle-mounted electric hoist which comprises a framework. The framework comprises a first platform, a second platform, a first power part, a first driven wheel and a first screw. The first platform and the second platform are parallel to each other and connected through columns. The first power part is arranged on the first platform. The first driven wheel is connected with the first power part and supported on the second platform through a bearing. A first opening is formed at the center of the first driven wheel, and inner threads are formed on the first opening in the circumferential direction. The first screw penetrates through the first opening of the first driven wheel, and outer threads of the first screw are meshed with the inner threads. A driving head of a first motor transmits power to the first driven wheel, the first driven wheel drives the first screw to ascend or descend in the vertical direction, and therefore a vehicle-mounted chassis is lifted. The vehicle-mounted electric hoist is simple in structure and convenient to operate and saves physical power.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted lifting mechanisms, and in particular relates to an electric lifting mechanism for an automobile chassis. Background technique [0002] This year, China's auto industry has developed vigorously. According to 2013 data, the total number of motor vehicles has exceeded 250 million. Among them, family cars account for a large proportion, and their ownership is still in the stage of rapid growth. When the car is running, if the tire is damaged and affects the normal driving, the driver needs to replace the spare tire in time. As a necessary maintenance tool for changing the tire, the car jack has always played an important role. However, traditional manual hydraulic jacks must be operated manually, which has a low safety factor and is time-consuming and labor-intensive, resulting in a greater psychological burden for users. Especially for some female operators, this kind of jack cannot be used normally a...
