Description

Technical Field

[0001] This application relates to the field of automotive structures, and in particular to the structure of suspension adjustment devices for electric vehicles. Background Technology

[0002] The electric vehicle suspension system is an important component of the electric vehicle chassis. Its main function is to connect the wheels to the vehicle body or frame, transmit the forces and torques between them, buffer the impact forces transmitted from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure the smoothness of the vehicle's ride, reduce the impact of vibrations on other structures such as the electric vehicle battery, and improve handling stability and ride comfort.

[0003] The basic structure of existing electric vehicle suspension includes a support axle disc connected to the wheel, with a fork arm hinged to the support axle disc and connected to the subframe or body. The support spring acts between the fork arm or a special suspension rod, and the vehicle height is changed by changing the pre-compression of the support spring or the position of the support point.

[0004] However, existing adjustable support springs typically use manual knobs or adjusting bolts to change the position of the support springs, which usually requires manual operation. This process is cumbersome, and drivers or maintenance personnel must operate the adjustment points manually with tools while the vehicle is stationary, resulting in low efficiency. Utility Model Content

[0005] The purpose of this application is to address the problem that existing adjustable support springs, as mentioned in the background art, typically use manual knobs or adjusting bolts to change the position of the support spring. This usually requires manual operation, which is cumbersome and inefficient. Drivers or maintenance personnel must operate the adjustment point manually with tools while the vehicle is stationary. This application provides a structure for an electric vehicle suspension adjustment device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An electric vehicle suspension adjustment device structure includes a support shaft disc, a fork arm rotatably connected to the support shaft disc, a fork arm rotatably connected to the support shaft disc, a suspension rod rotatably connected to the fork arm, a suspension rod slidably connected to the suspension rod, a fixed disc 2 fixed to the suspension rod 2, a fixed disc 1 slidably sleeved on the suspension rod 1, a support spring provided between the fixed disc 1 and the fixed disc 2, both ends of the support spring being fixedly connected to the fixed disc 1 and the fixed disc 2, an adjustment mechanism provided between the fixed disc 1 and the suspension rod 1, and an auxiliary fixing mechanism provided between the fixed disc 1 and the suspension rod 1.

[0008] By adopting the above technical solution, the adjusting mechanism drives the fixed plate one to move on the suspension rod one, changing the position of the support spring one, so that the distance between the suspension rod one and the suspension rod two changes, thereby making it convenient to adjust the position of the support point of the support spring, and convenient to adjust the height of the frame supported by the suspension rod two, reducing the trouble of manual adjustment.

[0009] Furthermore, the adjustment mechanism includes a support base fixed to one end of suspension rod one away from suspension rod two, a plurality of circumferentially distributed adjustment rods fixed on the support base, a support rod slidably connected to the adjustment rods, an abutment head fixed to one end of the support rod away from the adjustment rod, a drive assembly provided on the support base, and a synchronous connection assembly provided between the three adjustment rods.

[0010] By adopting the above technical solution, the drive assembly injects hydraulic oil into the adjusting rod using the synchronous connection component, allowing the support rod to move on the adjusting rod. The support rod then drives the fixed plate one to move, thereby facilitating the adjustment of the position of the fixed plate one. This allows the fixed plate one to change its support position on the support spring, and conveniently adjusts the height of the suspension rod two supporting the chassis frame.

[0011] Furthermore, the drive assembly includes a support tube fixed on a support base, a hydraulic rod fixed inside the support tube, an extrusion disc fixed to the telescopic end of the hydraulic rod, and the extrusion disc being slidably connected to the support tube.

[0012] By adopting the above technical solution, hydraulic oil is injected into the support tube, and the hydraulic rod drives the extrusion plate to squeeze the hydraulic oil, allowing the hydraulic oil to enter the adjusting rod, thereby facilitating the movement of the support rod within the adjusting rod.

[0013] Furthermore, the synchronous connection assembly includes a connecting four-way fixed on the support tube, the connecting four-way being connected to the support tube, and a plurality of connecting tubes fixed on the connecting four-way, the connecting tubes corresponding to the adjusting rod.

[0014] By adopting the above technical solution, the hydraulic oil in the support pipe enters the connecting pipe from the connecting four-way valve, and then enters the adjusting rod from the connecting pipe, thus facilitating the simultaneous entry of the hydraulic oil in the support pipe into the adjusting rod.

[0015] Furthermore, a solenoid valve is fixed to the end of the connecting pipe away from the connecting four-way valve, and the solenoid valve is fixedly connected to the adjusting rod.

[0016] By adopting the above technical solution, after the hydraulic oil enters the adjusting rod, the connection between the connecting pipe and the adjusting rod is blocked by a solenoid valve, thereby reducing the possibility of the hydraulic oil in the adjusting rod flowing back into the adjusting rod.

[0017] Furthermore, a support ring is slidably connected to the first suspension rod, the support ring has a groove, the first fixing plate is located in the groove of the support ring, and the contact head is fixedly connected to the support ring.

[0018] By adopting the above technical solution, the contact head on the support rod pushes the support ring, and the support ring drives the fixed plate to move, thereby reducing the possibility of uneven force on the fixed plate, which could lead to the twisting of the fixed plate.

[0019] Furthermore, the auxiliary fixing mechanism includes several support buckles fixed to the bottom of the support ring, a fixing rod slidably connected to the support buckle, a fixing block fixed on the fixing rod, several evenly distributed annular fixing grooves on the suspension rod, the fixing block corresponding to the fixing groove, and a pushing component provided between the fixing rod and the support ring.

[0020] By adopting the above technical solution, the fixing rod on the support buckle drives the fixing block to be inserted into the fixing groove on the suspension rod, thereby using the fixing block to further limit the support ring and improve the stability of the support ring support.

[0021] Furthermore, the pushing component includes a fixing buckle fixed on the support ring, and an electric telescopic rod is fixed on the fixing buckle. The telescopic end of the electric telescopic rod is fixedly connected to the fixing rod.

[0022] By adopting the above technical solution, the electric telescopic rod on the fixing buckle is used to drive the fixing rod to move, thereby making it convenient for the fixing rod to drive the fixing block to move.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application utilizes a hydraulic rod controlled by the tram control center. The hydraulic rod drives a compression plate, which in turn compresses hydraulic oil in the support pipe. The hydraulic oil enters the connecting pipe through the connecting four-way connector. Simultaneously, the solenoid valve on the connecting pipe opens, allowing hydraulic oil to enter the adjusting rod. The hydraulic oil lifts the support rod in the adjusting rod, which in turn lifts the contact head. The contact head lifts the support ring, which in turn lifts the fixed plate one. The fixed plate one compresses the support spring, which in turn pushes the fixed plate one, causing the fixed plate one to move the suspension rod two. This changes the height of the suspension rod two on the suspension rod one, thus changing the height of the suspension rod two supporting the chassis. Finally, the solenoid valve closes, keeping the hydraulic oil stable in the adjusting rod. This achieves the goal of easily adjusting the position of the fixed plate one, changing the support position of the fixed plate one on the support spring, and facilitating the adjustment of the height of the suspension rod two supporting the chassis, reducing the inconvenience of manual adjustment.

[0025] 2. In this application, when the solenoid valve is closed, the electric telescopic rod is controlled by the tram control center to drive the fixed rod, which in turn drives the fixed block. The fixed block is then inserted into the fixed groove on the suspension rod. The fixed block further supports and limits the support ring. When the support rod on the adjusting rod lifts the support ring, the position of the support ring is adjusted so that the fixed block aligns with the fixed groove, facilitating the insertion of the fixed block into the fixed groove. This achieves the purpose of further limiting the support ring using the fixed block, thereby improving the stability of the support ring. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses the structure of an electric vehicle suspension adjustment device.

[0034] Reference Figure 1 , Figure 2 and Figure 3The structure of the electric vehicle suspension adjustment device includes a support shaft disk 3, a fork arm 1 rotatably connected to the support shaft disk 3, a fork arm 2 rotatably connected to the support shaft disk 3, a suspension rod 4 rotatably connected to the fork arm 1, a suspension rod 5 slidably connected to the suspension rod 4, a fixing disk 10 fixed to the suspension rod 5, a fixing disk 9 slidably sleeved on the suspension rod 4, a support spring 6 provided between the fixing disk 9 and the fixing disk 2 10, both ends of the support spring 6 being fixedly connected to the fixing disk 9 and the fixing disk 2 10, an adjustment mechanism 7 provided between the fixing disk 9 and the suspension rod 4, and an auxiliary fixing mechanism 8 provided between the fixing disk 9 and the suspension rod 4.

[0035] During the installation of the electric vehicle suspension, the corresponding wishbone 1 and wishbone 2 are installed to their respective chassis positions. The end of suspension rod 2 5 furthest from suspension rod 4 is also installed onto the frame. The corresponding tire is installed on the support axle disc 3. The adjustment mechanism 7 and the auxiliary fixing mechanism 8 are connected to the electric vehicle's control center. The adjustment mechanism 7 on suspension rod 1 4 supports the fixing disc 9. The support spring 6 between the fixing disc 1 9 and the fixing disc 2 10 supports suspension rod 2 5. When it is necessary to adjust the support position of the upper support spring 6, the electric vehicle control center directly controls the adjustment mechanism 7 to move the fixing disc 9, allowing the fixing disc... The first plate 9 moves on the first suspension rod 4, and the fixed plate 9 changes the support position of the support spring 6. The support spring 6 presses against the fixed plate 10, causing the second suspension rod 5 to slide within the second suspension rod 5, thus changing the support height of the second suspension rod 5. Finally, the auxiliary mechanism is used to further fix the adjustment mechanism 7, completing the adjustment. By using the adjustment mechanism 7 to drive the fixed plate 9 to move on the first suspension rod 4, the support position of the first support spring 6 is changed, causing the distance between the first suspension rod 4 and the second suspension rod 5 to change. This allows for convenient adjustment of the support point position of the support spring 6, and convenient adjustment of the height of the frame supported by the second suspension rod 5, reducing the trouble of manual adjustment.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 7 includes a support seat 77 fixed to one end of the suspension rod 4 away from the suspension rod 5. Several circumferentially distributed adjustment rods 71 ​​are fixed on the support seat 77. Support rods 72 are slidably connected to the adjustment rods 71. An abutment head 73 is fixed to one end of the support rod 72 away from the adjustment rod 71. A drive assembly 74 is provided on the support seat 77. A synchronous connection assembly 75 is provided between the three adjustment rods 71.

[0037] In addition, the drive assembly 74 includes a support tube 741 fixed on the support base 77, a hydraulic rod 742 fixed inside the support tube 741, and a pressing disc 743 fixed to the telescopic end of the hydraulic rod 742. The pressing disc 743 is slidably connected to the support tube 741.

[0038] Furthermore, the synchronous connection assembly 75 includes a connecting four-way connector 751 fixed on the support tube 741. The connecting four-way connector 751 is connected to the support tube 741. Several connecting tubes 752 are fixed on the connecting four-way connector 751, and the connecting tubes 752 correspond to the adjusting rod 71.

[0039] Furthermore, a solenoid valve 753 is fixed at the end of the connecting pipe 752 away from the connecting four-way valve 751, and the solenoid valve 753 is fixedly connected to the adjusting rod 71.

[0040] Furthermore, a support ring 76 is slidably connected to the suspension rod 4. The support ring 76 has a groove, and the fixing plate 9 is located in the groove of the support ring 76. The contact head 73 is fixedly connected to the support ring 76.

[0041] Hydraulic oil is filled in the support tube 741. The space inside the support tube 741 is connected to the space inside the adjusting rod 71 via the connecting tube 752 and the connecting four-way connector 751. When adjusting the position of the fixed plate 9, the tram control center controls the hydraulic rod 742, which drives the extrusion plate 743. The extrusion plate 743 extrudes the hydraulic oil in the support tube 741. The hydraulic oil enters the connecting tube 752 through the connecting four-way connector 751. At the same time, the solenoid valve 753 on the connecting tube 752 opens, allowing hydraulic oil to enter the adjusting rod 71. The hydraulic oil lifts the support rod 72 in the adjusting rod 71. The support rod 72 lifts the contact head 73, and the contact head 73 lifts the support ring 76. The support ring 76 then secures the fixed plate 9. When the first plate 9 is lifted, the fixed plate 9 compresses the support spring 6, causing the support spring 6 to push the fixed plate 9, which in turn drives the second suspension rod 5, changing the height of the second suspension rod 5 on the first suspension rod 4. This changes the height of the second suspension rod 5 supporting the chassis. Finally, the solenoid valve 753 closes, keeping the hydraulic oil stable in the adjusting rod 71. By injecting hydraulic oil from the support pipe 741 into the adjusting rod 71, the hydraulic oil lifts the support rod 72 in the adjusting rod 71, causing the support rod 72 to lift the fixed plate 9 on the support ring 76. This allows for easy adjustment of the position of the fixed plate 9, changing its support position on the support spring 6, and facilitating the adjustment of the height of the second suspension rod 5 supporting the chassis.

[0042] Reference Figure 1 , Figure 2 and Figure 4 The auxiliary fixing mechanism 8 includes several support buckles 84 fixed to the bottom of the support ring 76. A fixing rod 81 is slidably connected to the support buckle 84. A fixing block 82 is fixed on the fixing rod 81. Several evenly distributed annular fixing grooves 83 are opened on the suspension rod 4. The fixing block 82 corresponds to the fixing groove 83. A pushing component 85 is provided between the fixing rod 81 and the support ring 76.

[0043] In addition, the pushing component 85 includes a fixing buckle 852 fixed on the support ring 76, and an electric telescopic rod 851 fixed on the fixing buckle 852. The telescopic end of the electric telescopic rod 851 is fixedly connected to the fixing rod 81.

[0044] When the solenoid valve 753 is closed, the electric telescopic rod 851 is controlled by the tram control center, causing the electric telescopic rod 851 to drive the fixed rod 81, which in turn drives the fixed block 82. The fixed block 82 is then inserted into the fixed groove 83 on the suspension rod 4. The fixed block 82 further supports and limits the support ring 76. When the support rod 72 on the adjusting rod 71 lifts the support ring 76, the position of the support ring 76 is adjusted so that the fixed block 82 aligns with the fixed groove 83, facilitating the insertion of the fixed block 82 into the fixed groove 83. After the support ring 76 drives the fixed disc 9 to move, the fixed block 82 on the support ring 76 is inserted into the fixed groove 83 on the suspension rod 4, thereby further limiting the support ring and improving the stability of the support ring.

[0045] Working principle: During the installation of the electric vehicle suspension, the corresponding wishbone 1 and wishbone 2 are installed to their respective chassis positions. The end of suspension rod 2 5 furthest from suspension rod 4 is also installed on the frame. The corresponding hub and tire are installed on the support axle plate 3. When adjusting the position of the fixing plate 9, the electric vehicle control center controls the hydraulic rod 742, which drives the compression plate 743. The compression plate 743 compresses the hydraulic oil in the support tube 741. The hydraulic oil enters the connecting pipe 752 through the connecting four-way connector 751. At the same time, the solenoid valve 753 on the connecting pipe 752 opens, allowing hydraulic oil to enter the adjusting rod 71. The hydraulic oil lifts the support rod 72 in the adjusting rod 71, which in turn lifts the contact head 73. The contact head 73 then lifts the support bracket. Ring 76, the support ring 76 lifts the fixed plate 9, the fixed plate 9 compresses the support spring 6, the support spring 6 pushes the fixed plate 9, the fixed plate 9 drives the suspension rod 5, changing the height of the suspension rod 5 on the suspension rod 4, changing the height of the suspension rod 5 supporting the chassis. Finally, the solenoid valve 753 closes, keeping the hydraulic oil stable in the adjusting rod 71. When the solenoid valve 753 is closed, the electric telescopic rod 851 is controlled by the tram control center, causing the electric telescopic rod 851 to drive the fixed rod 81, causing the fixed rod 81 to drive the fixed block 82, causing the fixed block 82 to insert into the fixing groove 83 on the suspension rod 4. The fixed block 82 further supports and limits the support ring 76, completing the adjustment of the support height of the suspension rod 4 and the suspension rod 5.
