[0019] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0020] like Figures 1 to 3As shown, the four-wheel drive transmission shaft combined bracket device includes a base plate 2, a fixed plate 3 is connected to one end of the bracket 1, a support block 4 is provided on the bracket 1, bearing seats 5 are provided on both sides of the base plate 2, the fixed plate 3 is located between the bearing seats 5, and a rotating shaft 6 is connected to the bearing seat 5 and the fixed plate 3.

[0021] This device makes low-cost and short-cycle modifications to traditional single-lift RGV equipment. The fixed base plate 2 of the four-wheel drive shaft bracket 1 is installed on the floating plate of the lifting platform of the single-lift RGV. The base plate 2 and the bracket 1 are fixed in a quick-plug and unplug manner. At the same time, a contoured support block is installed on the bracket 1 to steadily lift the four-wheel drive shaft, allowing the drive shaft and the powertrain to be lifted and assembled synchronously, thereby realizing the ability to quickly switch between two-wheel drive and four-wheel drive vehicles in co-production.

[0022] The base plate 2 of the drive shaft bracket 1 is designed as a rotating shaft 6. After the bracket 1 is plugged in and fixed and locked with the locating pin 8, the bracket 1 is fixed to the fixed plate 3, and the fixed plate 3 is rotatably connected to the bearing seat 5. The fixed plate 3 is mounted on the base plate 2, and a certain gap is set between the two to meet the rotation of the fixed plate 3 and the bracket 1. After the assembly is completed, if an object or a person touches the bracket 1, the bracket 1 will convert its vertical movement with the descent of the single-lift RGV into a rotation around the hinge point of the bearing seat 5, that is, the posture of the bracket 1 changes from horizontal to inclined, thereby avoiding extrusion damage or injury to objects or personnel, and improving the safety of the drive shaft dynamic assembly.

[0023] like Figure 2-1 and Figure 2-2 As shown, a mounting groove 7 is provided in the fixing plate 3, and the end of the bracket 1 is inserted into the mounting groove 7. A positioning pin 8 is provided at the upper end of the fixing plate 3, which passes through the fixing plate 3 and is connected to the bracket 1. The above structure realizes the plug-in installation of the bracket 1, and the positioning pin 8 is used to fix it to the fixing plate 3 to prevent relative displacement, facilitating the rapid insertion and removal of the bracket 1, so that the bracket 1 can be quickly assembled and disassembled according to the four-wheel drive or two-wheel drive transmission shaft assembly.

[0024] like Figure 1 As shown, the bracket 1 is provided with a fixing groove 9, which is the same length as the bracket 1. The support bracket 4 includes a bracket 10, and the bracket 10 is provided with a connecting groove 11. Bolts are provided on the connecting groove 11 to connect with the fixing groove 9 to achieve the fixation of the support bracket 4. The support bracket 4 can move freely with the fixing groove 9 to ensure that it is supported at the appropriate position of the transmission shaft. There are three support brackets 4, and the arc-shaped grooves of the three support brackets 4 are at different heights with the bracket 10, which can meet the support requirements of parts of the transmission shaft with different diameters.

[0025] like Figure 1As shown, the upper end of the support block 4 is an arc-shaped structure, and the bracket 10 is a T-shaped structure. The support block 4 forms an arc-shaped groove structure, which is adapted to the shape of the transmission shaft, which is conducive to improving the support stability of the transmission shaft. The bracket 10 is designed to be T-shaped to ensure that the support block 4 is more stable on the bracket 1.

[0026] like Figure 2-1 and Figure 2-2 As shown, sleeves 12 are provided on both sides of the fixing plate 3, and one end of the rotating shaft 6 is located in the sleeve 12. The sleeve 12 is provided to help keep the rotating shaft 6 horizontal, and also to prevent the rotating shaft 6 from being exposed and damaged or rusted, thereby ensuring its reliable rotation function.

[0027] like Figure 1 As shown, a pad 13 is provided at the end of the bracket 1. The pad 13 can prevent the sharp part of the bracket 1 from causing damage to personnel, and at the same time cushion the impact of the bracket 1 during the lifting or lowering process.

[0028] The bracket 1 is made of aluminum alloy. The bracket 1 is made of aluminum alloy and weighs less than 15KG, which is convenient for employees to install or store the bracket 1.

[0029] A base plate 2 is fixed to the floating plate of the single-lift RGV by bolts, and a bearing seat 5 is fixed to the base plate 2 by bolts. According to the size of the four-wheel drive shaft, a bracket 1 with three contoured support blocks 4 is made to support the four-wheel drive shaft. The support blocks 4 are fixed to the bracket 1 by bolts and can be moved on the bracket 1 to ensure that the four-wheel drive shaft will not fall; the bracket 1 is installed with the fixed plate 3 by a combination of plug-in and locating pins 8, which is convenient for quick installation and disassembly. The bearing seat 5 is connected to the fixed plate 3 by a rotating shaft 6 to realize the rotation of the bracket 1 to avoid the risk of squeezing and injury to the operator.

[0030] A bracket storage fixture 14 is placed at the installation station for storing the bracket 1; when producing a four-wheel drive vehicle, the operator takes a bracket 1 from the bracket storage fixture 14, inserts it into the base plate 2, and inserts the positioning pin 8 to assemble the four-wheel drive vehicle; when producing a two-wheel drive vehicle, the operator can unplug the positioning pin 8, pull out the bracket 1 and store it on the bracket storage fixture 14, and the single-lift RGV can normally lift the drive shaft part of the two-wheel drive vehicle assembly.

[0031] The four-wheel drive shaft combined bracket device is a modification of the existing single-lift RGV structure. By adding a bracket 1 that can be easily disassembled, it meets the demand for rapid switching between two-wheel drive and four-wheel drive vehicles in the same production line, reducing the modification cost. At the same time, the bearing seat 5 and the rotating shaft 6 structure are provided to realize the rotatable function of the bracket 1, avoiding the squeeze injury to personnel caused by the drive shaft bracket 1 during the descent of the single-lift RGV. The support block 4 has a reasonable structural design and can provide reliable support for the drive shaft. The various components in the device are reliably connected, easy to disassemble, and easy to operate.

[0032] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
