The present invention provides a lifting device for an automobile, as shown in fig. 1, the lifting device 100 includes a lifting body 110 and a supporting block 120. The supporting blocks 120 are disposed on the top of the lifting body 110, and the supporting blocks 120 are disposed on both sides of the lifting body 110 along a first direction, the first direction is a left-right direction shown in fig. 1 and corresponds to a left-right direction of the automobile, the supporting blocks 120 on the left and right sides of the lifting body 110 are respectively used for supporting the left and right sides of the automobile, and the bottom of the lifting body 110 is used for connecting a lifting driving member (e.g., a jack), so that the lifting driving member drives the lifting body 110 to lift the automobile upwards. The utility model discloses supporting shoe 120 has all been set up in the left and right sides of lifting the main part 110, and the left and right sides of car can be supported respectively to the supporting shoe 120 of the left and right sides for the left and right sides of car can be in step by jack-up, especially when maintaining and maintaining traditional independent suspension cross country vehicle's suspension, use the utility model discloses a lifting device 100 can lift the lower control arm of the car left and right sides in step, just so can make traditional independent suspension cross country vehicle's frame front end place on the technology supports, be convenient for maintenance and maintenance.

In addition, the utility model discloses in, with supporting shoe 120 with lift the adjustable connection of main part 110, make supporting shoe 120 the position on lifting main part 110 adjustable like this, just also can make lifting device 100 be applicable to the motorcycle type of different sizes.

Use the utility model discloses a during lifting device 100, use a jack can lift the left and right sides of car, guaranteed the synchronism that the left and right sides lifted, when lifting, the jack was at the intermediate position of lifting device 100 bottom to make the even supporting shoe 120 of distribution of lifting force ability both sides, simultaneously, guarantee the stationarity that lifting device 100 lifted. In one embodiment, as shown in fig. 2, the lifting body 110 is an inverted isosceles triangle, and includes two obliquely disposed side beams 111 and a top support plate 112 disposed on top of the two side beams 111, two ends of the top support plate 112 are respectively connected to the tops of the two side beams 111, the top support plate 112 and the two side beams 111 together form an isosceles triangle, and the two side beams 111 are respectively two waists of the isosceles triangle. The lifting main body 110 is configured as an isosceles triangle to ensure the stability of the lifting main body 110. The lifting body 110 includes two side beams 111 and a top support plate 112, so that the lifting body 110 is similar to a bracket structure, rather than forming the lifting body 110 by a solid block of material, which can reduce the weight of the lifting body 110 and save material. The side beam 111 can be a section which is of a hollow structure, so that the weight is light, and the weight can be further reduced. The top support plate 112 is made of a hot-rolled thick steel plate, the side members 111 are welded to the top support plate 112, and the hot-rolled thick steel plate is good in rigidity and capable of bearing and resisting deformation.

Referring to fig. 2, in one embodiment, a bottom support plate 113 is disposed at the bottom of the lifting body 110, and a jack is disposed on the bottom support plate 113 during lifting, and since the side beams 111 are formed of a section bar, it is not easy to directly contact with the jack to receive the lifting force, so that a bottom support plate 113 is disposed at the bottom of the lifting body 110 to abut against the jack. The bottom support plate 113 is arranged to improve the strength of the joint between the lifting device 100 and the jack, and the jack is arranged on the bottom support plate 113 to protect the lifting device 100 from being damaged. As shown in fig. 2, the bottom supporting plate 113 is disposed at the top corner of the isosceles triangle, so that the jack can be positioned at the middle position of the bottom of the lifting body 110, and the lifting force can be uniformly distributed to the two lifted sides of the automobile, so that the lifting device 100 is more stable during the lifting process. The bottom support plate 113 may be a hot-rolled thick steel plate, which has high support strength and high deformation resistance.

In order to facilitate the positioning of the jack on the bottom support plate 113 during lifting, as shown in fig. 3 and 4, a limiting retaining ring 1131 may be disposed at the bottom of the bottom support plate 113, the limiting retaining ring 1131 is used for limiting the jack, the limiting retaining ring 1131 is circular ring-shaped, and has an inner diameter substantially the same as the diameter of the top of the jack, so that the jack is limited in the limiting retaining ring 1131 during lifting and cannot move, thereby ensuring the safety during lifting.

In one embodiment, as shown in fig. 2, the support block 120 is adjustably connected to the top support plate 112 by bolts, and the support block 120 can be adjusted to the mounting position by providing a plurality of screw holes 1121 at different positions on the top support plate 112.

Referring to fig. 2, a plurality of screw holes 1121 are formed in the top support plate 112 at intervals in the left-right direction, so that the support block 120 can be adjusted in position on the top support plate 112 in the left-right direction, and the lifting device 100 can be applied to automobiles with different sizes.

Referring to fig. 2, an elastic pad 130 is disposed on the contact surface of the supporting block 120 and the vehicle to protect the paint surface of the vehicle. Resilient pad 130 protects the paint surface of the lower control arm of a conventional independent suspension all terrain vehicle when supported by support block 120. The elastic pad 130 may be vulcanized rubber.

In order to prevent the elastic pad 130 from interfering with the installation of the supporting block 120, as shown in fig. 2, an avoiding hole 131 may be formed in the elastic pad 130 to avoid the bolt, as shown in fig. 1, the bolt head of the bolt may be hidden in the avoiding hole 131, so that the installation of the supporting block 120 may not be interfered, and the coverage of the elastic pad 130 may be wider.

In one embodiment, as shown in fig. 2, a limit stop 121 is disposed on the supporting block 120, and the limit stop 121 is disposed vertically for positioning the lifting device 100 with the vehicle. When the lower control arm of traditional independent suspension cross country vehicle supported on supporting shoe 120, limit baffle 121 can the butt in the outside of control arm down, prevents to take place to sideslip, guarantees the security of lifting.

Limiting baffle 121's the outside is provided with reinforcing plate 122, and reinforcing plate 122 is right triangle, and one of them right-angle side is connected with limiting baffle 121, and another right-angle side is connected with supporting shoe 120, and reinforcing plate 122 can promote limiting baffle 121's intensity, prevents that limiting baffle 121 from warping. Limiting baffle 121, reinforcing plate 122 and supporting shoe 120 can integrated into one piece, can promote the wholeness like this, reduce the quantity of scattered part, simplify the structure, promote assembly efficiency.

As shown in fig. 1 and 2, the supporting block 120 is bolted to the top supporting plate 112 by 6M 8 bolts, and the 6 bolts are grouped two by two into three groups, and the three groups of bolts are spaced apart in the left-right direction. The limit stop 121 is disposed between the rightmost set of bolts and the middle set of bolts, and the reinforcement plate 122 is disposed between two bolts of the rightmost set of bolts.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments.
