Embodiment Construction

[0020] Examples such as Figures 1 to 5 As shown, a fixing device for a spare tire of an automobile comprises a spare tire fixing bracket 2 fixed in a spare tire groove 1, a spare tire fixing pressure plate 3 compatible with the spare tire, and the spare tire fixing bracket 2 is fixed with the spare tire At least three connecting bolts 4 are arranged between the pressing plates 3, preferably three connecting bolts. A group of welding nuts 5 matching the connecting bolts 4 are arranged below the spare tire fixing bracket 2 . The connecting bolts 4 are arranged on the same circumference and are adapted to the mounting holes of the spare tire. A group of fixing holes 10 matched with the connecting bolts 4 are arranged on the fixing pressure plate 3 of the spare tire, and the fixing holes 10 are waist-shaped holes arranged along the diameter direction.

[0021] In order to improve the assembly efficiency and the consistency of the pre-tightening force of the connecting bolts, a ...

Abstract

The invention discloses a vehicle spare tire fixing device, comprising a spare tire fixing support fixed in a spare tire groove, and a spare tire fixing pressing plate. At least three connecting bolts are arranged between the spare tire fixing support and the spare tire fixing pressing plate. A group of welding nuts which are adaptive to the connecting bolts are arranged under the spare tire fixing support. Compared with a conventional spare tire fixing device, the device can preferably fix a spare tire, and prevents displacement of the spare tire. The device has better fatigue resistance and endurance performance. The device is simple in operation, and is more convenient to install than installation of a conventional spare tire fixing device, and the device saves efforts. In addition, the device gives full consideration on an aluminum ring installation hole structure of an actual vehicle, and has very good versatility. The device can be widely used in the field of vehicle spare tire installation and fixation.

Description

technical field [0001] The invention relates to the field of fixing an automobile spare tire, in particular to a spare tire fixing device capable of limiting the horizontal movement and up and down jump of the automobile spare tire. Background technique [0002] When the car is running, it will be excited by random loads from the ground. Different road surface characteristics will cause different degrees of deformation and vibration of the vehicle. There are many additional parts on the vehicle, including seats, dashboards, air conditioners, etc. Interior parts, the loads on these interior parts vary according to the mass, the greater the mass of the part, the greater the inertial force. Therefore, for parts with high mass such as seats and instrument panel assemblies, more installation points will be arranged on the vehicle body, so that they can be placed more stably during the driving process of the car, and the quality of the spare tire of the car is relatively low. Lar...
