[0004] At present, as different countries and regions adopt different standards and use environments for complete vehicles according to the global market demand, and because the same model, the same seat, different rows and diversified functions need to meet customer delivery requirements, and with the rise of intelligent car manufacturing and the gradual increase in car manufacturers' requirements for suppliers, the complete vehicle loading requirements have also brought about major changes in the seat delivery mode and transportation requirements, from the delivery of a set of trolleys (such as the comparative document publication number CN205973077U mentioned below) to the supply of complete vehicle installation needs by a single carrier, that is, the complete vehicle assembly requires the front and rear left seats to be loaded on the left side, and the right seats to be loaded on the right side. This can improve the JPH efficiency of the car factory assembly, reduce the use of seat trolleys, and avoid logistics chaos caused by too many trolleys; this requirement leads to the need to share seat shipping carriers, which poses an extremely difficult challenge to how seat suppliers can ensure delivery.

The first transmission shaft is rotated by a chain sprocket driven by the output end of the motor. Sprockets are respectively provided on the two ends of the first transmission shaft and the second transmission shaft. A lifting chain is wound around the sprockets. The chain that bypasses the sprocket of the second transmission shaft also bypasses the sprocket on the first transmission shaft to realize the rotation of the second transmission shaft when the first transmission shaft rotates. The first end of each lifting chain is connected to the counterweight.

Specific implementation method:

[0028] In order to make the above features and advantages of the present invention more obvious and easy to understand, the following embodiments are specifically described in detail with reference to the accompanying drawings;

[0030] Pulley mechanisms are fixedly provided on all four sides of the lifting platform 129, and the free ends of the chains of the chain mechanisms are connected to the pulley mechanisms.

[0031] The pulley mechanism 137 includes two parallel fixed plates 158 arranged at intervals, four guide columns are evenly distributed and connected between the two fixed plates 158, and a compressed spring group 159 is sleeved on the four guide columns and located between the two fixed plates 158.

[0032] The second fixed plate is provided with two rollers (roller 161, roller 162) and a built-in roller 160, and a T-shaped track 157 is provided on the column 156. The groove of the built-in roller 160 is limited to roll in the T-shaped track 157, and the two rollers abut against the side of the T-shaped track 157 and roll.

[0033] The built-in roller 160 is mainly used for the longitudinal fitting movement of the T-shaped track 157 on the equipment column 156. The four guide columns are inserted into the spring group 159 to absorb the excess stress during the movement and ensure the smooth operation of each pulley mechanism. The rollers 161 and 162 are used to increase the running friction on the side of the T-shaped track 157 on the equipment column 156. The fixed block 165 is connected to the fixed plate 158 and is used to fix one end of the chain (such as chain A145).

[0034] The chain mechanism that drives the lifting platform 129 to rise and fall includes two parallel transmission shafts located on the upper surface of the frame, namely the first transmission shaft 149 and the second transmission shaft 153. The first transmission shaft 149 is rotated by a chain sprocket driven by the output end of the motor 147. Sprockets are respectively provided on the two ends of the first transmission shaft 149 and the second transmission shaft 153, and a lifting chain is wound around the sprockets. The chain that bypasses the sprocket of the second transmission shaft 153 also bypasses the sprocket on the first transmission shaft 149, so that the second transmission shaft 153 can be driven to rotate when the first transmission shaft 149 rotates.

[0035] The first end of each lifting chain is connected to the counterweight block 141, and the second end of the lifting chain is fixedly connected to the first fixed plate. There are 5 groups of sprockets on the first transmission shaft 149, one group of which is used to connect with the chain driven by the output end of the motor 147, two groups of which are used to wind the chains of the two fixed plates of the lifting platform 129 on one side, and two groups of which are used to wind the chains of the two fixed plates of the lifting platform 129 on the other side (that is, the chains 145 and 146 also wound around the sprockets on the second transmission shaft 153).

[0036] A first lifting transmission mechanism 132 and a second lifting transmission mechanism 171 are respectively provided in the first speed line 130 and the second speed line 131, an auxiliary wheel 133 and a first blocking device 134 and a second blocking device 135 which can be raised and lowered are provided between the first speed line 130 and the second speed line 131, and a blocking block 140 is provided on the outer side of the second speed line 131.

[0037] The first speed line 130 and the second speed line 131 are used to transport the finished seats to the seat docking line 4; the loaded seat carrier flows into the first lifting transmission mechanism 132, and transitions to the second lifting transmission mechanism 171 through the auxiliary wheel 133. The ends of the second lifting transmission mechanism 171 are limited by the blocking blocks 140 on both sides to prevent the loaded seat carrier from rolling out of the second lifting transmission mechanism 171. When there is a seat in the second lifting transmission mechanism 171, the first blocking device 134 and the second blocking device 135 (which can be a baffle driven by a cylinder to rise and fall) located between the first lifting transmission mechanism 132 and the second lifting transmission mechanism 171 rise to block the next loaded seat carrier to prevent it from flowing into the second lifting transmission mechanism 171 and the second speed line 131. After the first lifting transmission mechanism 132 and the second lifting transmission mechanism 171 are lowered, the loaded seat carriers at the two places fall on the first speed line 130 and the second speed line 131 to wait for an opportunity to be transported to the seat docking line 4.

[0038] The pulley mechanism 136 is connected to the counterweight block 141 through the chain B146, and the chain B146 is driven by the first transmission shaft 149 and the second transmission shaft 153. The pulley mechanism 137 is connected to the counterweight block 141 through the chain A145, and the chain A145 is driven by the first transmission shaft 149 and the second transmission shaft 153. The pulley mechanism 138 is connected to the counterweight block 141 through the chain D155 and is driven by the first transmission shaft 149, and is linked through the outer sprocket 151. The pulley mechanism 139 is connected to the counterweight block 141 through the chain A145. The chain A145 is driven by the first transmission shaft 149 and the second transmission shaft 153. It is connected through chain C154 and driven by the first transmission shaft 149, and is linked to the outer sprocket group 150. The sprocket group 150 and the sprocket 152 are coaxially connected to the sprocket 151 through the first transmission shaft 149. The motor 147 is linked to the sprocket 152 in the sprocket group 150 through the chain through its front end sprocket group, thereby driving the first transmission shaft 149 and the second transmission shaft 153 to rotate, and drives the lifting mechanism 129 to lift and lower with the help of chains 145, 146, 154, and 155.

[0039] The pulley mechanism 137 has two fixed plates 158, and the built-in roller 160 is mainly used for the longitudinal fitting movement of the T-track 157 on the equipment column 156. The four guide columns are inserted into the spring group 159 to absorb the excess stress during the movement to ensure the smooth operation of each pulley mechanism. The rollers 161 and 162 are used to increase the running friction on the side of the T-track 157 on the equipment column 156. The tensioners 163 and 164 are used to keep the rollers 161 and 162 with appropriate tension during the transmission process to avoid derailment and reduce wear. The fixed block 165 is connected to the fixed plate 158 and is used to fix one end of the chain (such as chain A145); the pulley mechanisms 137 and 139 are symmetrical with the pulley mechanisms 136 and 138.

[0040] The lifting mechanism 129 is positioned by contacting the sensor of the equipment column 156 through the metal sheet at the rear end of the pulley mechanism 137. Sensors 166 and 167 are used for the lifting mechanism 12 to connect with the seat connecting line 4 on the second floor (double-layer mechanism). Sensors 168 and 169 are used for the lifting mechanism 12 to connect with the seat connecting line 4 on the first floor. Sensor 170 is the origin for stopping the lifting mechanism 129.

[0041] The above description is only an embodiment of the present invention. Any equivalent changes or modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
