Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of battery cell automotive suspensions, and specifically to a battery cell automotive suspension capable of resisting torsion. Background Art
[0002] An automotive suspension is the general term for all force transmission connecting devices between the frame (or load-bearing body) of an electric vehicle and the axle (or wheel). Its function is to transmit the force and torque acting between the wheel and the frame, and buffer the impact force transmitted from the uneven road surface to the frame or body, and reduce the resulting vibration to ensure that the vehicle can drive smoothly.
[0003] When a conventional automotive suspension is fixed to the chassis, it is relatively single, fixed by bolts and nuts, and the bolts are exposed, which will accelerate the aging of the bolts over a long time, reduce the strength of the bolts. When the bolts age and become loose or break, the fixing effect between the suspension and the chassis becomes poor, the torque balance is broken, and it is easy to damage the battery cells. Summary of the Invention
[0004] In view of the deficiencies of the prior art, the present invention provides a battery cell automotive suspension capable of resisting torsion, which solves the problems raised in the above background art.
[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A battery cell automotive suspension capable of resisting torsion, including a multi-link suspension, a shielding device is provided on the multi-link suspension, an alarm device is provided on the multi-link suspension, and a pressing device is provided on the multi-link suspension;
[0006] Among them, the shielding device includes: a short sliding rod, a first spring, a backing plate, a long sliding rod, a second spring, a limiting rod, a transmission slider, a transmission spring, a shielding cover plate and a shielding plate. The short sliding rod slides in the notch on the multi-link suspension. A backing plate is fixed above the short sliding rod. A first spring slides on the short sliding rod, and the first spring slides in the notch on the first spring, and the end point of the first spring is fixed below the backing plate.
[0007] According to the above technical solution, a long sliding rod is fixed below the backing plate. The long sliding rod slides in the notch on the multi-link suspension. A second spring slides on the long sliding rod, and the second spring slides in the notch on the multi-link suspension. The end point of the second spring is fixed below the backing plate, and a limiting rod is fixed below the long sliding rod.
[0008] According to the above technical solution, the transmission slider slides in the notch on the multi-link suspension. A transmission spring is fixed on the transmission slider, and the transmission spring slides in the notch on the multi-link suspension.
[0009] According to the above technical solution, a shielding cover plate is fixed below the transmission slider, and a shielding plate is fixed below the multi-link suspension. The limiting rod slides in the notch on the shielding cover plate. When the nut rotates and clamps on the bolt, the first spring and the second spring give an upward supporting force to the backing plate, making the nut clamp more tightly on the bolt and reducing sliding. While the nut rotates and clamps on the bolt, the long sliding rod drives the limiting rod to move downward, causing the limiting rod to slide downward in the notch on the shielding cover plate, releasing the limit on the shielding cover plate. Under the action of the transmission spring, the transmission spring presses the transmission slider, causing the transmission slider to approach the shielding plate. The movement of the transmission slider towards the shielding plate drives the shielding cover plate to approach the shielding plate, making the shielding cover plate and the shielding plate fit together, preventing rainwater from directly contacting the bolt, slowing down the aging of the bolt, and avoiding accidents caused by the change of the torque of the battery cell due to the fracture of the bolt. When maintenance is required, the nut is loosened and separated from the bolt, and the shielding cover plate is pulled to slide away from the shielding plate on the limiting rod and then reset. The first spring and the second spring no longer receive the downward pressure from the backing plate. Under the elastic force of the first spring and the second spring, the backing plate moves upward. The upward movement of the backing plate drives the long sliding rod to move upward, resetting the long sliding rod. The reset of the long sliding rod drives the limiting rod to slide upward and reset. The limiting rod restricts the position of the shielding cover plate, facilitating maintenance.
[0010] According to the above technical solution, the alarm device includes a control module, a pressure sensor, a support spring, a support rod, a pressing plate, a pressing block, and an alarm. The control module is fixed in the notch of the shielding cover plate, and the pressure sensor is fixed on the control module.
[0011] According to the above technical solution, the support spring slides in the notch of the shielding cover plate. One end of the support spring is fixed below the inner wall of the notch of the shielding cover plate, and the other end of the support spring is fixed with a support rod. The support rod slides in the notch of the shielding cover plate. The end point of the support rod is fixed with a pressing plate, and a pressing block is fixed below the pressing plate. An alarm is fixed below the shielding cover plate. When the bolt becomes loose and moves downward, the downward displacement of the bolt presses the pressing plate, causing the pressing plate to drive the pressing block to press the pressure sensor downward. When the pressure data of the pressure sensor changes due to the extrusion, the control module controls the alarm to give an alarm. When maintenance is required, the shielding cover plate is reset so that the pressing plate no longer contacts the bolt. The pressing plate no longer receives the pressure from the bolt. Under the action of the support spring, the support rod is reset. The support rod drives the pressing plate and the pressing block to reset, and the value of the pressure sensor is restored. The control module controls the alarm to turn off the alarm.
[0012] According to the above technical solution, the tightening device includes a fixed shaft, a rotating rod, a C-shaped plate, a pressure spring, a limiting block, a sliding spring, a sliding block, and a pressing block. The fixed shaft is fixed on the shielding plate, the rotating rod penetrates and rotates on the fixed shaft, and the C-shaped plate is hinged on the rotating rod.
[0013] According to the above technical solution, a pressure spring slides in the notch on the C-shaped plate. A limit block is fixed below the pressure spring. The limit block slides in the notch on the C-shaped plate. The sliding spring slides in the notch of the multi-link suspension. One end of the sliding spring is fixed with a sliding block. The sliding block slides in the notch on the multi-link suspension. A pressing block is fixed above the sliding block. The limit block slides in the notch on the pressing block. When the pressing plate moves downward, the pressing plate squeezes the C-shaped plate, causing the C-shaped plate to rotate on the rotating rod on the fixed shaft, causing the limit block to squeeze the pressing block, causing the limit block to contract into the notch on the C-shaped plate under the action of the pressure spring, so that the limit block no longer contacts the pressing block. The pressing block and the sliding block move toward the bolt under the action of the sliding spring, causing the pressing block to press the bolt tightly, preventing the bolt from loosening further. When maintenance is required, the pressing plate resets and no longer squeezes the C-shaped plate. The C-shaped plate is squeezed and reset, pulling the pressing block closer to the shielding plate, causing the limit block on the C-shaped plate to slide into the notch on the pressing block, limiting the pressing block.
[0014] The present invention provides a multi-link suspension for an electric vehicle that can resist torsion. It has the following beneficial effects:
[0015] (1) The present invention is provided with a shielding device. When the nut rotates and tightens, the first spring and the second spring give an upward supporting force to the backing plate, making the nut clamp tighter. At the same time as the nut rotates and tightens, the limit rod releases the limit, and the shielding cover plate fits with the shielding plate, preventing rainwater from directly contacting the bolt in rainy and foggy weather, slowing down the aging speed of the bolt, maintaining the strength of the bolt, preventing the suspension from breaking due to bolt aging and causing torque changes in the electric core during vehicle driving, ensuring the safety of the electric core, and reducing potential safety hazards.
[0016] (2) The present invention is provided with an alarm device. When the nut loosens and the bolt moves downward, the bolt squeezes the pressing plate, causing a data change in the pressure sensor. The control module controls the alarm to sound, enabling the vehicle driver to quickly detect the bolt loosening during driving and send it for repair in time, preventing the bolt from loosening and causing torque changes in the electric core, and reducing potential safety hazards.
[0017] (3) The present invention is provided with a tightening device. When the bolt loosens and squeezes the pressing plate, the pressing plate causes the C-shaped plate to rotate, releasing the limit on the pressing block. The pressing block moves toward the bolt under the action of the sliding spring and squeezes the bolt, preventing the bolt from loosening further, reducing the torque change in the electric core caused by bolt loosening, and making the vehicle safer during driving.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer to Figures 1 - 8, an embodiment of the present invention is: a battery cell vehicle suspension that can resist torsion. It includes a multi-link suspension 1, and a shielding device 2 is arranged on the multi-link suspension 1; wherein the shielding device 2 includes: a short sliding rod 201, a first spring 202, a backing plate 203, a long sliding rod 204, a second spring 205, a limiting rod 206, a transmission slider 207, a transmission spring 208, a shielding cover plate 209 and a shielding plate 210. The short sliding rod 201 slides in the notch on the multi-link suspension 1. A backing plate 203 is fixed above the short sliding rod 201. A first spring 202 slides on the short sliding rod 201, and the first spring 202 slides in the notch on the first spring 202. The end point of the first spring 202 is fixed below the backing plate 203. A long sliding rod 204 is fixed below the backing plate 203. The long sliding rod 204 slides in the notch on the multi-link suspension 1. A second spring 205 slides on the long sliding rod 204, and the second spring 205 slides in the notch on the multi-link suspension 1. The end point of the second spring 205 is fixed below the backing plate 203. A limiting rod 206 is fixed below the long sliding rod 204. The transmission slider 207 slides in the notch on the multi-link suspension 1. A transmission spring 208 is fixed on the transmission slider 207, and the transmission spring 208 slides in the notch on the multi-link suspension 1. A shielding cover plate 209 is fixed below the transmission slider 207. A shielding plate 210 is fixed below the multi-link suspension 1. The limiting rod 206 slides in the notch on the shielding cover plate 209. When the nut rotates and tightens, the first spring 202 and the second spring 205 give an upward supporting force to the backing plate 203, making the nut clamp tighter. At the same time when the nut rotates and tightens, the limiting rod 206 releases the limit, and the shielding cover plate 209 fits with the shielding plate 210, preventing rainwater from directly contacting the bolt in rainy and foggy weather, slowing down the aging speed of the bolt, keeping the strength of the bolt, and preventing the suspension from breaking due to bolt aging, which may cause changes in the torque of the battery cell during vehicle driving, ensuring the safety of the battery cell and reducing potential safety hazards.
[0029] During the operation of this embodiment: When the nut rotates and clamps on the bolt, the first spring 202 and the second spring 205 provide an upward supporting force to the backing plate 203, making the nut clamp more tightly on the bolt, reducing slippage. While the nut rotates and clamps on the bolt, the long sliding rod 204 drives the limiting rod 206 to move downward, causing the limiting rod 206 to slide downward in the notch on the shielding cover plate 209, releasing the limit on the shielding cover plate 209. Under the action of the transmission spring 208, the transmission spring 208 squeezes the transmission slider 207, causing the transmission slider 207 to approach the baffle plate 210. The transmission slider 207 moves towards the baffle plate 210, driving the shielding cover plate 209 to approach the baffle plate 210, making the shielding cover plate 209 and the baffle plate 210 fit together, preventing rainwater from directly contacting the bolt, slowing down the aging of the bolt, and avoiding accidents caused by the change of the torque of the battery cell due to the fracture of the bolt. When maintenance is required, the nut loosens and separates from the bolt. Pull the shielding cover plate 209 to make it slide away from the baffle plate 210 on the limiting rod 206 and then reset. The first spring 202 and the second spring 205 no longer receive the downward pressure of the backing plate 203. Under the elastic force of the first spring 202 and the second spring 205, the backing plate 203 moves upward. The upward movement of the backing plate 203 drives the long sliding rod 204 to move upward, resetting the long sliding rod 204. The reset of the long sliding rod 204 drives the limiting rod 206 to slide upward and reset. The limiting rod 206 limits the position of the shielding cover plate 209, facilitating maintenance.
[0030] Please refer to Figures 1 - 8 , based on the above embodiment, in another embodiment of the present invention, an alarm device 3 is provided on the multi-link suspension 1, and a pressing device 4 is arranged on the multi-link suspension 1. The alarm device 3 includes a control module 301, a pressure sensor 302, a support spring 303, a support rod 304, a pressing plate 305, a pressing block 306, and an alarm 307. The control module 301 is fixed in the notch of the shielding cover plate 209. The pressure sensor 302 is fixed on the control module 301, and the control module 301 is electrically connected to the pressure sensor 302. The support spring 303 slides in the notch on the shielding cover plate 209. One end of the support spring 303 is fixed below the inner wall of the notch of the shielding cover plate 209, and the other end of the support spring 303 is fixed with a support rod 304. The support rod 304 slides in the notch on the shielding cover plate 209. The end point of the support rod 304 is fixed with a pressing plate 305, and a pressing block 306 is fixed below the pressing plate 305. The alarm 307 is fixed below the shielding cover plate 209, and the alarm 307 is electrically connected to the control module 310. When the nut loosens and the bolt moves downward, the bolt presses the pressing plate 305, causing the pressure sensor 302 to generate a data change. The control module 301 controls the alarm 307 to alarm, enabling the vehicle driver to quickly detect the loosening of the bolt during driving and send it for repair in time, avoiding the change of the torque of the battery cell due to the loosening of the bolt and reducing potential safety hazards.
[0031] The tightening device 4 includes a fixed shaft 401, a rotating rod 402, a C-shaped plate 403, a pressure spring 404, a limit block 405, a sliding spring 406, a sliding block 407 and a pressing block 408. The fixed shaft 401 is fixed on the shielding plate 210. The rotating rod 402 penetrates and rotates on the fixed shaft 401. The C-shaped plate 403 is hinged on the rotating rod 402. The pressure spring 404 slides in the notch on the C-shaped plate 403. The limit block 405 is fixed below the pressure spring 404. The limit block 405 slides in the notch on the C-shaped plate 403. The sliding spring 406 slides in the notch of the multi-link suspension 1. The end point of the sliding spring 406 is fixed with the sliding block 407. The sliding block 407 slides in the notch on the multi-link suspension 1. The pressing block 408 is fixed above the sliding block 407. The limit block 405 slides in the notch on the pressing block 408. When the bolt loosens and the bolt presses the pressing plate 305, the pressing plate 305 presses the C-shaped plate 403 to make the C-shaped plate 403 rotate, so that the pressing block 408 is released from the limit. The pressing block 408 moves close to the bolt under the action of the sliding spring 406, presses the bolt, avoids further loosening of the bolt, reduces the change of the torque of the battery cell caused by the loosening of the bolt, and makes the vehicle safer during driving.
[0032] When this embodiment works: when the bolt loosens and the bolt moves downward, the bolt moves downward and presses the pressing plate 305, so that the pressing plate 305 drives the pressing block 306 to press the pressure sensor 302 downward. When the pressure data of the pressure sensor 302 changes due to being pressed, the control module 301 controls the alarm 307 to give an alarm. When maintenance is required, the shielding cover plate 209 is reset so that the pressing plate 305 no longer contacts the bolt, and the pressing plate 305 no longer receives the bolt pressure. Under the action of the supporting spring 303, the supporting rod 304 is reset, and the supporting rod 304 drives the pressing plate 305 and the pressing block 306 to reset, the value of the pressure sensor 302 is restored, and the control module 301 controls the alarm 307 to turn off the alarm.
[0033] When the pressing plate 305 moves downward, the pressing plate 305 presses the C-shaped plate 403, so that the C-shaped plate 403 rotates on the rotating rod 402 on the fixed shaft 401, so that the limit block 405 presses the pressing block 408, so that the limit block 405 contracts into the notch on the C-shaped plate 403 under the action of the pressure spring 404, so that the limit block 405 no longer contacts the pressing block 408. The pressing block 408 and the sliding block 407 move close to the bolt under the action of the sliding spring 406, so that the pressing block 408 presses the bolt tightly to avoid further loosening of the bolt. When maintenance is required, the pressing plate 305 is reset and no longer presses the C-shaped plate 403, the C-shaped plate 403 is reset by extrusion, pulling the pressing block 408 close to the shielding plate 210, so that the limit block 405 on the C-shaped plate 403 slides into the notch on the pressing block 408, and the pressing block 408 is limited.
[0034] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
