Description

Technical Field

[0002] In the field of automotive engineering, suspension refers to the elastic connection components used to connect the powertrain such as the engine and gearbox to the vehicle frame. The automotive motor suspension is an important component of electric vehicles. Its main function is to reduce the vibration and noise generated by the powertrain during operation, improve riding comfort and safety, and protect the vehicle body and powertrain from damage.

[0003] When manufacturing cars, workers use special EC wrenches with mechanical arms to fix the suspension body. EC wrenches with mechanical arms can automatically detect the torque and automatically determine whether the suspension is fixed on the body beam. After the car suspension is inspected and repaired, the suspension body is reinstalled on the body beam. Since EC wrenches with mechanical arms are expensive, the inspection workers can only judge whether the suspension body is fixed based on experience.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Embodiment 1

[0035] See also Figure 1 and Figure 2A new energy vehicle motor suspension assembly includes a suspension body 1, a wheel cover mounting frame 2, a buffer structure 3 and a connecting structure 4. The wheel cover mounting frame 2 is fixedly connected to the top of one side of the suspension body 1 and at the middle position of the top. A mounting hole is opened at the bottom of the suspension body 1, and the buffer structure 3 is fixedly installed in the mounting hole. The connecting structure 4 is fixedly connected to one side of the buffer structure 3, and the connecting structure 4 passes through and extends out of the side wall of the other side of the suspension body 1. Fixing holes 101 for passing hexagonal flange bolts 5 are opened at both ends of the suspension body 1.

[0036] See also Figure 2 and Figure 3 , extrusion grooves 102 are provided on the suspension body 1 on both sides of the fixing hole 101, the connection line of the two extrusion grooves 102 is perpendicular to the center line of the wheel cover mounting frame 2, and an extrusion slider 103 is installed in the extrusion groove 102 in a sliding seal, and the upper end surface of the extrusion slider 103 is higher than the end surface of the top of the fixing hole 101; please refer to Figure 6 and Figure 7 A transversely arranged detection hole 104 is provided on the side wall at the bottom end of one of the extrusion grooves 102, and a detection slider 105 is slidably and sealedly installed in the detection hole 104. The detection slider 105 is located in the middle position of the detection hole 104, and an observation hole 106 is provided on the suspension body 1 at the middle position of the top end of the detection hole 104. An observation rod 107 is slidably installed in the observation hole 106, and the bottom end of the observation rod 107 is fixedly connected to the detection slider 105. The observation rod 107 can slide horizontally or vertically in the observation hole 106, and when the observation rod 107 slides, the detection slider 105 always seals the bottom end of the observation hole 106, and the extrusion groove 102 and the detection hole 104 at the bottom end of the extrusion slider 103 are filled with high-pressure gas, and the observation rod 107 is located at one end of the observation hole 106 close to the extrusion slider 103.

[0037] Scale bars are fixedly embedded on both sides of the top of the observation hole 106, and a pointing slot is provided at the top of the observation rod 107, and the top of the observation rod 107 is lower than the end surface of the top of the observation hole 106. When the hexagonal flange bolt 5 is fixed to the suspension body 1, the hexagonal flange bolt 5 is prevented from squeezing the observation rod 107, causing the observation rod 107 to bend, resulting in subsequent deviation of the pointing slot on the observation rod 107.

[0038] The working principle of the first embodiment of the present invention is as follows:

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7When the suspension body 1 is installed on the vehicle body beam, the hexagonal flange bolt 5 is passed through the fixing hole 101 of the suspension body 1. When the hexagonal flange bolt 5 is rotated, the flange of the hexagonal flange bolt 5 squeezes the extrusion slider 103, so that the extrusion slider 103 slides into the extrusion groove 102. In the process of the extrusion slider 103 sliding into the extrusion groove 102, the high-pressure gas in the extrusion groove 102 is squeezed again. Since the air pressure in the extrusion groove 102 increases, the air pressure of the high-pressure gas in the detection hole 104 is less than the air pressure in the extrusion groove 102. The air pressure in the extrusion groove 102 will push the detection slider 105 to move into the detection hole 104, thereby balancing the air pressure on both sides of the detection slider 105. When the detection slider 105 moves to the detection hole 104, the detection slider 105 moves to the detection hole 104. During the movement in the detection hole 104, the detection slider 105 drives the observation rod 107 to slide in the observation hole 106. When the extrusion slider 103 pushes the high-pressure gas in the extrusion groove 102 to reach the rated value, it means that the extrusion pressure between the extrusion slider 103 and the flange of the hexagonal flange bolt 5 reaches the limit value, and the hexagonal flange bolt 5 has fixed the suspended suspension body 1 on the vehicle body beam. At this time, the detection slider 105 drives the observation rod 107 to move to a limited position. The worker can observe the position of the observation rod 107 with the naked eye, thereby judging that the hexagonal flange bolt 5 has fixed the suspended suspension body 1 on the vehicle body beam, thereby preventing the worker from judging whether it is fixed based on his own experience, resulting in poor fixing effect.

[0040] Embodiment 2

[0041] When the hexagonal flange bolt 5 is used to fix the suspension body 1 on the vehicle body beam, since the diameter of the fixing hole 101 of the suspension body 1 is larger than the diameter of the hexagonal flange bolt 5, after the suspension body 1 is fixed with the hexagonal flange bolt 5, a movable gap will be generated between the hexagonal flange bolt 5 and the inner wall of the fixing hole 101, and vibration will be generated during the driving of the vehicle. The vibration will cause the suspension body 1 and the fixing hole 101 to shake toward the hexagonal flange bolt 5, thereby causing abnormal noise to be generated in the suspension and the motor installed on the suspension. Embodiment 2 is a further improvement on Embodiment 1.

[0042] The difference from the first embodiment is that, please refer to Figure 2-Figure 5A connecting groove 108 is provided in the middle of the two extrusion grooves 102 and at the outer circle of the fixing hole 101. The two ends of the connecting groove 108 are connected to the top of the extrusion groove 102. The depth of the connecting groove 108 is less than the depth of the extrusion groove 102 to prevent the connecting groove 108 from being connected to the extrusion groove 102 at the bottom of the extrusion slider 103. A connecting arc plate 109 is installed in the connecting groove 108 for sliding sealing. The two ends of the connecting arc plate 109 are fixedly connected to the extrusion slider 103. A limiting groove 110 is provided in the middle of the bottom of the connecting groove 108. The limiting groove 110 is connected to the fixing hole 101. The limiting groove 110 slides in the limiting groove 110. A power block 111 is installed, and the power block 111 can slide toward the axis direction of the fixing hole 101. The limiting block is fixedly installed at the position where the limiting groove 110 is connected to the fixing hole 101. An elastic block 113 is fixedly installed at the position of the power block 111 facing the limiting block. The other end of the elastic block 113 is against the limiting block. When the elastic block 113 is squeezed by the outside, it will be deformed. When the external squeezing force disappears, the elastic block 113 returns to its original state. A limiting rubber block 112 is fixedly installed on the power block 111 facing the side of the fixing hole 101 and located between the two limiting blocks. The limiting rubber block 112 can be deformed.

[0043] The top of the connecting arc plate 109 is not higher than the top of the extrusion slider 103, and the height of the connecting arc plate 109 is less than the depth of the connecting groove 108. When the hexagonal flange bolt 5 pushes the extrusion slider 103, the upper end surface of the connecting arc plate 109 is prevented from being too high, which affects the extrusion of the extrusion slider 103 by the hexagonal flange bolt 5, resulting in abnormal extrusion of the high-pressure gas in the extrusion groove 102, affecting the judgment of whether the hexagonal flange bolt 5 has completed the fixation of the suspension body 1; and the connecting groove 108 is prevented from being too deep so that the connecting groove 108 is connected with the extrusion groove 102 at the bottom of the extrusion slider 103.

[0044] The end surface of the limiting rubber block 112 facing the fixing hole 101 is flush with the inner wall of the fixing hole 101 , so as to prevent the limiting rubber block 112 from penetrating into the fixing hole 101 , thereby preventing the hexagonal flange bolt 5 from being blocked by the limiting rubber block 112 when being inserted into the fixing hole 101 .

[0045] The working principle of the second embodiment of the present invention is as follows:

[0046] See also Figure 1-Figure 7When the suspension body 1 is installed on the vehicle body beam, the hexagonal flange bolt 5 is passed through the fixing hole 101 of the suspension body 1. When the hexagonal flange bolt 5 is rotated, the flange of the hexagonal flange bolt 5 squeezes the extrusion slider 103, so that the extrusion slider 103 slides into the extrusion groove 102. During the movement of the extrusion slider 103, the extrusion slider 103 drives the connecting arc plate 109 to move into the connecting groove 108. At this time, the connecting arc plate 109 moving into the connecting groove 108 squeezes the power block 111, so that the power block 111 moves toward the fixing hole 102. 1, and during the movement of the power block 111, the power block 111 drives the limiting rubber block 112 to move, so that the limiting rubber blocks 112 on both sides are close to the hexagonal flange bolt 5, so that the hexagonal flange bolt 5 is in the middle position of the fixing hole 101, and the limiting rubber block 112 fills the gap between the hexagonal flange bolt 5 and the fixing hole 101, so that the hexagonal flange bolt 5 is in a fixed position, thereby preventing the suspension body 1 from shaking due to the gap between the hexagonal flange bolt 5 and the fixing hole 101.

[0047] Embodiment 3

[0048] After the suspension body 1 is fixed to the vehicle body beam using the hexagonal flange bolts 5, various vibrations are generated when the vehicle is running, and the vibration of the vehicle may cause the hexagonal flange bolts 5 to loosen, thereby weakening the fixation of the hexagonal flange bolts 5 to the suspension body 1, causing the suspension and the motor fixed on the suspension to move abnormally. Embodiment 3 is a further improvement on Embodiment 2.

[0049] The difference from the second embodiment is that please refer to Figure 8-Figure 10 A mounting groove 115 is provided in the suspension body 1 and on the side of the observation hole 106. The bottom end of the mounting groove 115 is connected to the detection hole 104. A tooth groove 114 is provided on the side of the detection slider 105 facing the mounting groove 115. A gear 117 is movably provided at the bottom end of the mounting groove 115. The gear 117 can move in the axial direction of the mounting groove 115. The gear 117 is meshed with the tooth groove 114 of the detection slider 105. A fixing groove 116 is provided on the suspension body 1 at the top of the mounting groove 115. The top of the fixing groove 116 is in the same plane as the top of the fixing hole 101, and the straight line where the fixing groove 116 is located passes through the center line of the fixing hole 101. A fixing rod 118 is installed in the mounting groove 115 in a sliding seal. The fixing rod 118 is divided into a cylindrical section and a fixed section. The cylindrical section of the fixing rod 118 is fixedly connected to the upper end surface of the gear 117, and a tension spring 119 is fixedly connected to the top of the cylindrical section of the fixing rod 118. The top of the tension spring 119 is fixedly connected to the top of the mounting groove 115.

[0050] See also Fig.11The hexagonal flange bolt 5 is an existing bolt for fixing the suspension body 1 , and a limiting groove 501 is provided at the bottom end of the flange surface of the hexagonal flange bolt 5 .

[0051] The top of the fixing section of the fixing rod 118 is an inclined surface. When the top of the fixing section of the fixing rod 118 is an inclined surface, a sharp point will be generated at the top of the fixing section of the fixing rod 118. When the top of the fixing section of the fixing rod 118 is inserted into the limiting groove 501 of the hexagonal flange bolt 5, the top of the fixing section of the fixing rod 118 can be inserted into the most concave position of the limiting groove 501, which is convenient for fixing the hexagonal flange bolt 5.

[0052] See also Fig.10 , the tension spring 119 is always in a tensioned state. The tension spring 119 in the tensioned state always generates a tension force, so that the tension spring 119 generates an upward tension force on the fixing rod 118. When the top end of the fixing rod 118 is no longer limited by the bottom end of the fixing groove 116, the tension spring 119 can pull the top end of the fixing rod 118 through the fixing groove 116, so that the top end of the fixing rod 118 is limited by the hexagonal flange bolt 5.

[0053] The cylindrical section of the fixing rod 118 is a permanent magnet. When disassembling, the fixing rod 118 is squeezed with a magnet that repels the magnetic poles of the cylindrical section of the fixing rod 118, so that the fixing rod 118 moves downward, and the limiting of the fixing rod 118 to the hexagonal flange bolt 5 is released.

[0054] The working principle of the third embodiment of the present invention is as follows:

[0055] See also Figure 1-Figure 11When the suspension body 1 is installed on the vehicle body beam, the hexagonal flange bolt 5 is passed through the fixing hole 101 of the suspension body 1. When the hexagonal flange bolt 5 is rotated, the flange of the hexagonal flange bolt 5 squeezes the extrusion slider 103, so that the extrusion slider 103 slides into the extrusion groove 102. During the sliding process of the extrusion slider 103 into the extrusion groove 102, the high-pressure gas in the extrusion groove 102 is squeezed again. Since the air pressure in the extrusion groove 102 increases, the air pressure of the high-pressure gas in the detection hole 104 is less than the air pressure in the extrusion groove 102. The air pressure in the extrusion groove 102 will push the detection slider 105 to move into the detection hole 104, thereby balancing the air pressure on both sides of the detection slider 105. During the movement of the detection slider 105 into the detection hole 104, due to the tooth groove 114 of the detection slider 105 and the gear 11 7 is meshed, the tooth groove 114 pushes the gear 117 to rotate, so that the gear 117 drives the fixing rod 118 to rotate. When the hexagonal flange bolt 5 pushes the extrusion slider 103 to fix the suspended suspension body 1, the detection slider 105 moves to the limited position in the detection hole 104. At this time, the tooth groove 114 of the detection slider 105 also drives the gear 117 to rotate to a certain angle, so that the fixing section of the fixing rod 118 can extend through the fixing groove 116. Under the tension of the tension spring 119, the fixing section of the fixing rod 118 extends out of the fixing groove 116, and the top end of the fixing end of the fixing rod 118 is inserted into the limiting groove 501 of the hexagonal flange bolt 5, thereby limiting the hexagonal flange bolt 5 to prevent the hexagonal flange bolt 5 from rotating, thereby preventing the hexagonal flange bolt 5 from rotating and causing the fixing to loosen during the vibration of the car.
