[0021] This utility model provides a front mounting structure for a push rod motor, including a front cross tube 101 of the seat cushion and a mounting assembly 102. The mounting assembly 102 includes a seat cushion side plate 103, a rear cross tube 104 of the seat cushion, a rear connecting rod 105 of the seat cushion, a front connecting rod 106 of the seat cushion, a mounting component 108, a connecting component 108, a motor lead screw 114, a front mounting hole 115 of the motor, a first step 116, and a second step 117. The mounting component 108 includes a front mounting bracket 109 of the seat cushion, a rear mounting bracket 110 of the seat cushion, and a push rod motor 118. The connecting component 108 includes a step bolt 112 and a step nut 113. The aforementioned solution tightens the inner width of the mounting bracket 119 by using the step bolt 112 and the step nut 113, reducing the amount of noise generated when the motor starts or reverses due to the installation gap, thereby achieving the effect of reducing abnormal noise.

[0022] In this specific embodiment, the seat cushion side plate 103 is fixedly connected to the front cross tube 101 of the seat cushion and is located on one side of the front cross tube 101. The rear cross tube 104 of the seat cushion is disposed on one side of the seat cushion side plate 103. The rear connecting rod 105 of the seat cushion is fixedly connected to the seat cushion side plate 103 and is located on one side of the seat cushion side plate 103. The front connecting rod 106 of the seat cushion is disposed on one side of the front cross tube 101. The mounting member 108 is disposed on one side of the seat cushion side plate 103. The connecting member 108 is disposed on the side of the seat cushion side plate 103. The seat cushion side plate 103 has a front motor mounting hole 115, which is located on one side of the seat cushion side plate 103. The front horizontal tube 101 is welded to the seat cushion side plate 103, and the rear horizontal tube 104 is riveted to the seat cushion side plate 103. The front horizontal tube 101 passes through the through hole of the front connecting rod 106. These connections are reinforced by the connecting member 108. The large diameter optical shaft of the bolt is tightly fitted with the inner hole of the stepped nut 113, and the small diameter thread of the bolt is tightened with the stepped nut 113. This adapts to the radial force requirement at the front bolt mounting point when the motor 120 moves the lead screw 114 to rotate, and the axial force requirement is small. Subsequently, the inner width of the mounting bracket is tightened by the bolts and nuts, and the amount of noise generated when the motor 120 starts or reverses due to the installation gap is reduced, thus reducing abnormal noise.

[0023] The front mounting bracket 109 of the seat cushion is threadedly connected to the front connecting rod 106 of the seat cushion and is located on one side of the front connecting rod 106. The rear mounting bracket 110 of the seat cushion is bolted to the rear connecting rod 105 of the seat cushion and is located on one side of the rear connecting rod 105. The push rod motor 118 is located on one side of the rear mounting bracket 110. The mounting bracket 119 is welded to the front horizontal tube 101 of the seat cushion. The connecting member 108 is welded to the mounting bracket 119. The axial and radial clearances at the front mounting position of the motor are eliminated by the clamping fit of the connecting member 108, thereby reducing abnormal noise.

[0024] Secondly, the stepped bolt 112 is threadedly connected to the front mounting hole 115 of the motor and is located on one side of the front mounting hole 115. The stepped nut 113 is fixedly connected to the stepped bolt 112 and is located on one side of the stepped bolt 112. The stepped bolt 112 and the stepped nut 113 are tightly fitted together to eliminate axial clearance. The optical axis of the stepped bolt 112 passes through the mounting bracket 119 and the inner hole of the stepped nut 113 and is tightly fitted together to eliminate radial clearance. The stepped bolt 112 and the stepped nut 113 tighten the inner width of the mounting bracket 119, reducing the amount of ore generated when the motor 120 starts or reverses due to installation clearance, thereby reducing abnormal noise. The large diameter optical axis of the stepped bolt 112 is tightly fitted with the inner hole of the stepped nut 113, and the small diameter thread of the stepped bolt 112 is tightened with the stepped nut 113, which is suitable for the working conditions where the radial force requirement at the installation location of the stepped bolt 112 is large and the axial force requirement is small.

[0025] Meanwhile, the motor 120 is fixedly connected to the rear bracket 111 of the push rod motor and is located on one side of the rear bracket 111 of the push rod motor. The lead screw 114 is fixedly connected to the output end of the motor 120 and is located on one side of the motor 120. The large diameter optical axis of the stepped bolt 112 is tightly fitted with the inner hole of the stepped nut 113, and the small diameter thread of the stepped bolt 112 is tightened with the stepped nut 113. This allows the output end of the motor 120 to drive the lead screw 114 to rotate. When the lead screw 114 rotates, because the radial force requirement at the front bolt mounting point is large and the axial force requirement is small, the effect of reducing abnormal noise is achieved.

[0026] In addition, the first step 116 is fixedly connected to the step bolt 112 and is located on one side of the step bolt 112. The second step 117 is fixedly connected to the step nut 113 and is located on one side of the step nut 113. The step bolt 112 is installed by cooperating with the motor front mounting hole 115 and the step nut 113. The first step 116 of the step bolt 112 and the second step 117 of the step nut 113 are tightly fitted to eliminate the axial and radial clearance of the motor front mounting and reduce abnormal noise.

[0027] In using this utility model, the front horizontal tube 101 of the seat cushion and the side plate 103 of the seat cushion are welded together, the rear horizontal tube 104 of the seat cushion and the side plate 103 of the seat cushion are riveted together, the front horizontal tube 101 of the seat cushion passes through the through hole of the front connecting rod 106 of the seat cushion, the front connecting rod 106 of the seat cushion and the front mounting bracket 109 of the seat cushion are connected by the stepped bolt 112, the rear connecting rod 105 of the seat cushion is welded to the rear horizontal tube of the seat cushion, the rear connecting rod 105 of the seat cushion and the rear mounting bracket 110 of the seat cushion are connected by the stepped bolt 112, and the rear bracket 111 of the push rod motor and the rear connecting rod 104 of the seat cushion are connected together. 5. The push rod motor rear bracket 111 and the motor lead screw 114 are connected by the stepped bolt 112. The mounting bracket 119 is welded to the front cross tube 101 of the seat cushion.
