Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive technology, and specifically relates to a jack bracket for vehicles and a vehicle. Background Technology
[0002] A jack is one of the most important tools in a vehicle. Users will use a jack when changing a tire or in other situations where the vehicle needs to be lifted. During the use of a jack, the jack support structure, as an important component of the lower part of the vehicle body, needs to have sufficient strength to withstand a certain load, ensuring that the body panels do not suffer serious deformation or damage during jacking operations, thus affecting the vehicle's appearance and lifespan.
[0003] Existing vehicle jack support structures often use a single sheet welded to the vehicle beam, or a pad to connect the vehicle beam and the hydraulic rod of the jack. This method results in a small force-bearing area and the pad is prone to slippage, which can cause damage to the vehicle beam from the hydraulic rod (because the hydraulic rod is relatively thin, the force-bearing area on the vehicle beam is small, thus causing damage to the vehicle beam).
[0004] Therefore, there is a need to provide a reasonably designed jack support structure for off-road vehicles to ensure the integrity of the vehicle's functionality in harsh environments such as off-road and desert conditions. This would prevent serious deformation or even damage to the vehicle body or frame when using the jack to support or lift the entire vehicle, thus affecting the product's appearance and vehicle safety. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a vehicle jack bracket, comprising a jack bracket and a rear longitudinal beam. The jack bracket is a truncated cone, and its first end face is fixedly connected to the lower surface of the rear longitudinal beam. The second end face of the jack bracket is provided with a jack support hole, and the area of the first end face is larger than the area of the second end face.
[0006] Furthermore, the jack support is frustum-shaped.
[0007] Furthermore, the jack support is formed by bending a piece of sheet metal.
[0008] Furthermore, the jack support includes side plates, and adjacent side plates are fixedly connected.
[0009] Furthermore, the outer surface of the side plate is provided with reinforcing ribs.
[0010] Furthermore, the jack support is frustum-shaped.
[0011] Furthermore, the jack support is formed by bending a piece of sheet metal.
[0012] Furthermore, the outer surface of the jack support is provided with reinforcing ribs.
[0013] An automobile includes a body and the aforementioned vehicle jack bracket, the body including a rear longitudinal beam, the first end face of the jack bracket being fixedly mounted on the lower surface of the rear longitudinal beam.
[0014] Furthermore, the rear longitudinal beam includes a bottom surface, and the bottom surface of the rear longitudinal beam is welded to the jack support.
[0015] The beneficial effects of this utility model are:
[0016] 1. The jack support of this utility model has a simple structure and is easy to install. The jack support is installed on the lower surface of the rear longitudinal beam by four-sided welding to form a closed cavity, which improves the strength of the jack support.
