Description

Technical Field

[0001] This utility model relates to the field of compression elastic elements, and in particular to a composite compression elastic element. Background Technology

[0002] Automotive compression springs generally refer to automotive parts that possess both compressibility and elasticity, and they are widely used in the automotive industry. These components typically require good mechanical properties, resistance to chemical substances, and processing performance. Composite springs are elastomers that combine metal coil springs and rubber into one unit, combining the advantages of both metal and rubber springs.

[0003] Elastic components in a vehicle primarily function in the suspension system. Damage to elastic components in the suspension system is usually caused by repeated, prolonged, large-angle deflections at the connection point between the elastic component and the structural components in the suspension system when the elastic component undergoes torsional deformation. This leads to breakage and damage at the connection point between the elastic component and the structural components in the suspension system, rendering the elastic component unusable. Utility Model Content

[0004] The purpose of this invention is to solve the problem that damage to the elastic components in the suspension system is usually caused by repeated large-angle deflections at the connection between the elastic component and the structural components in the suspension system when the elastic component undergoes torsional deformation, resulting in breakage and damage at the connection between the elastic component and the structural components in the suspension system, thus rendering the elastic component unusable. A composite compression elastic component for automobiles is proposed to address this issue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite automotive compression elastic component, comprising an elastic component body, wherein the elastic component body is an elastic body composed of a metal helical spring and rubber, and an auxiliary device is provided at the bottom end of the elastic component body for protecting the elastic component body when a large torque is generated on the elastic component body, wherein the auxiliary device includes a base, and a circular block is rotatably connected to the inner wall of the base, and the top end of the circular block is fixedly connected to the bottom end of the elastic component body.

[0006] The effect achieved by the above components is that when connecting the composite compression elastic element to the vehicle's suspension system, the elastic element body is installed by welding the base to the structural components of the suspension system.

[0007] Preferably, slot blocks are installed on both sides of the base using convenient components. A slider is slidably connected to one end of the inner wall of the slot block, and a stop block is fixedly connected to the top of the slider. The stop block is located above the circular block, and a circular rod is fixedly connected to one side of the stop block. The end of the circular rod away from the stop block is slidably connected to the inner wall of the slot block, and a stop rod is fixedly connected to the top of the inner wall of the slot block. The stop rod is made of the same material as the elastic element, and both ends of the stop rod are connected to the inner wall of the slot block by welding.

[0008] The effect achieved by the above components is as follows: when the elastic element is working, when it is subjected to a large lateral force, it will cause the round block inside the base to deflect in one direction. The top of the round block will abut against the bottom of the stop block on one side of the base. When the force exceeds a certain limit, the round block will rotate upward and push the stop block to make the slider slide on the inner wall of the groove block. This will cause the round rod on one side of the stop block to push the stop rod to bend and break away from the stop block. Then the round block continues to rotate upward and the torque on the elastic element will disappear.

[0009] Preferably, the bottom edge of the stop is arc-shaped, and the bottom edge of the stop has a smooth outer surface.

[0010] The effect achieved by the above components is that by setting the bottom edge of the stop to be arc-shaped and smooth, when the round block rotates upward and contacts the bottom surface of the stop, it can smoothly push the stop through the slider to push the rectangular rod.

[0011] Preferably, the convenient component includes a bolt, the base has slots on both sides, the base has threaded holes on both sides, the outer surface of the bolt is threaded to the inner wall of the threaded hole, and the outer surface of the slot block has a through hole.

[0012] The effect achieved by the above components is as follows: insert one end of the slot into the slot on both sides of the base so that half of the slot is completely inside the slot. Then, insert the bolt into the threaded hole and rotate the bolt to connect with the threaded hole. The bolt passes through the through hole on the outer surface of the slot, so that the slot can be installed on the outer surface of the base. After the auxiliary device operates and the rectangular rod on the outer surface of the base breaks, the bolt can be rotated to disengage the bolt from the threaded hole. Then, the slot can be pulled out from the slot to facilitate the re-welding of the rectangular rod.

[0013] Preferably, an elastic rope is fixedly connected to one side of the top of the base, and one end of the elastic rope is fixedly connected to one end of a bolt.

[0014] The effect achieved by the above components is that by setting elastic ropes, the bolts can always be fixed on the outer surface of the base, making them easy to pick up and use when installing the slot blocks and preventing the bolts from falling off or being lost.

[0015] Preferably, the outer surface of the groove block is provided with a protective device, the protective device including a rectangular plate, two inserts are fixedly connected to the bottom end of the rectangular plate, elastic metal sheets are fixedly connected to both sides of the inserts, and two slots are opened at the top end of the groove block, the internal shape of the slots being an inverted T shape.

[0016] The effect achieved by the above components is as follows: after the slot blocks are installed on the outer surface of the base, the two inserts at the bottom of the rectangular plate can be inserted into the two slots at the top of the slot blocks. When the inserts are inserted into the slots, the two metal pieces will bend inward at a certain angle. As the inserts continue to go deeper, the two elastic metal pieces will spring outward and lock into the slots, fixing the position of the inserts inside the slots and fixing the rectangular plate to the top of the slot blocks. When the auxiliary device is in operation, the rectangular plate can block the broken rectangular rod inside the slot blocks to prevent the rectangular rod fragments from leaking into the vehicle suspension system.

[0017] Preferably, the top of the rectangular plate has two auxiliary grooves, which are mirror images of each other on the top of the rectangular plate.

[0018] The effect achieved by the above components is as follows: when removing the rectangular plate, you can pinch the two auxiliary slots at the top of the rectangular plate and pull the rectangular plate outward to deform the elastic metal sheets on the outer surface of the two inserts, and then pull the inserts out of the slots.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by setting an auxiliary device, the bottom end of the elastic element is connected to the circular block, and the base is connected to the structural components of the vehicle suspension system to connect the elastic element to the suspension system. When the elastic element is subjected to a large torque, the circular block rotates, pushing the stop block and the circular rod to move and push the rectangular rod out, so that the circular block can drive the elastic element to rotate, thus eliminating the torque on the elastic element. This avoids directly connecting the elastic element to the structural components of the suspension system and improves the service life of the elastic element. Attached Figure Description

Detailed Implementation

[0027] Example 1, such as Figure 1 and Figure 2 As shown, a composite automotive compression elastic component includes an elastic component body 1, which is an elastic body composed of a metal coil spring and rubber. The bottom end of the elastic component body 1 is provided with an auxiliary device 2 for protecting the elastic component body 1 when a large torque is generated. The auxiliary device 2 includes a base 21, and a circular block 22 is rotatably connected to the inner wall of the base 21. The top end of the circular block 22 is fixedly connected to the bottom end of the elastic component body 1. When the composite compression elastic component is connected to the vehicle's suspension system, the elastic component body 1 is welded to the structural components of the suspension system through the base 21.

[0028] Reference Figure 2-4 As shown in this embodiment: Slot blocks 24 are installed on both sides of the base 21 via convenient components 23. A slider 25 is slidably connected to one end of the inner wall of the slot block 24. A stop block 26 is fixedly connected to the top of the slider 25, and the stop block 26 is located above the circular block 22. A circular rod 27 is fixedly connected to one side of the stop block 26. The end of the circular rod 27 away from the stop block 26 is slidably connected to the inner wall of the slot block 24. A stop rod 28 is fixedly connected to the top of the inner wall of the slot block 24. The stop rod 28 is made of the same material as the elastic element 1. Both ends of the stop rod 28 are connected to the inner wall of the slot block 24 by welding. When the elastic element 1 is working, when subjected to a large lateral force, it will cause the circular block 22 inside the base 21 to deflect in one direction. The top of the circular block 22 will abut against the bottom of the stop block 26 on one side of the base 21. When the force exceeds a certain limit... The circular block 22 rotates upwards, pushing the stop block 26 to make the slider 25 slide on the inner wall of the groove block 24. This causes the circular rod 27 on one side of the stop block 26 to push the stop rod 28 away from the stop block 26, causing it to bend and break. Then, the circular block 22 continues to rotate upwards, causing the torque on the elastic element 1 to disappear. By setting the auxiliary device 2, the bottom end of the elastic element 1 is connected to the circular block 22, and the base 21 is connected to the structural components of the vehicle suspension system, thus connecting the elastic element 1 to the suspension system. When the elastic element 1 is subjected to a large torque, the circular block 22 rotates, pushing the stop block 26 and the circular rod 27 to move and push the rectangular rod out. This allows the circular block 22 to drive the elastic element 1 to rotate, causing the torque on the elastic element 1 to disappear. This avoids directly connecting the elastic element 1 to the structural components of the suspension system, thus improving the service life of the elastic element.

[0029] Reference Figure 2-4 As shown in this embodiment: the bottom edge of the stop 26 is arc-shaped and the bottom edge of the stop 26 is a smooth outer surface. By setting the bottom edge of the stop 26 to be arc-shaped and a smooth outer surface, when the circular block 22 rotates upward and contacts the bottom surface of the stop 26, it can smoothly push the stop 26 to move through the slider 25 to push the rectangular rod.

[0030] Reference Figure 2-4 As shown in this embodiment: The base 21 has convenient components 23 on both sides for easy assembly and disassembly of the slot block 24. The convenient components 23 include bolts 233. The base 21 has slots 231 on both sides and threaded holes 232 on both sides. The outer surface of the bolts 233 is threaded to the inner wall of the threaded holes 232. The outer surface of the slot block 24 has through holes 234. One end of the slot block 24 is inserted into the slots 231 on both sides of the base 21, so that half of the slot block 24 is completely inside the slots 231. Then, the bolts 233 are inserted into the threaded holes 232 and rotated to connect with the inner wall of the threaded holes 232, thus ensuring the bolts 233 are properly threaded. By passing through the through hole 234 on the outer surface of the slot 24, the slot 24 can be installed on the outer surface of the base 21. After the rectangular rod on the outer surface of the base 21 breaks due to the operation of the auxiliary device 2, the bolt 233 can be rotated to disengage from the threaded hole 232. Then, the slot 24 can be pulled out from the slot 231 to facilitate the re-welding of the rectangular rod. An elastic rope 235 is fixedly connected to one side of the top of the base 21. One end of the elastic rope 235 is fixedly connected to one end of the bolt 233. By setting the elastic rope 235, the bolt 233 can always be fixed on the outer surface of the base 21, which is convenient for picking up and using when installing the slot 24 and prevents the bolt 233 from falling off and being lost.

[0031] Reference Figure 1 , Figure 4 and Figure 5As shown in this embodiment: a protective device 3 is provided on the outer surface of the slot block 24. The protective device 3 includes a rectangular plate 32. Two inserts 33 are fixedly connected to the bottom end of the rectangular plate 32. Elastic metal sheets 34 are fixedly connected to both sides of the inserts 33. Two slots 31 are opened at the top end of the slot block 24. The internal shape of the slots 31 is inverted T-shaped. After the slot block 24 is installed on the outer surface of the base 21, the two inserts 33 at the bottom end of the rectangular plate 32 can be inserted into the two slots 31 at the top end of the slot block 24. When the inserts 33 are inserted into the slots 31, the two metal sheets 34 will bend inward at a certain angle. As the inserts 33 continue to penetrate, the two elastic metal sheets 34 will bend outward. The outer spring is locked inside the slot 31 to fix the position of the insert 33 inside the slot 31, and fixes the rectangular plate 32 to the top of the slot block 24. When the auxiliary device 2 is in operation, the rectangular plate 32 can block the broken rectangular rod inside the slot block 24 to prevent the rectangular rod fragments from leaking into the vehicle suspension system. The top of the rectangular plate 32 has two auxiliary slots 35, which are mirrored on the top of the rectangular plate 32. When the rectangular plate 32 is removed, the rectangular plate 32 can be pulled outward by pinching the two auxiliary slots 35 at the top of the rectangular plate 32, so that the elastic metal sheet 34 on the outer surface of the two inserts 33 will deform, and the inserts 33 can be pulled out from the inside of the slot 31.

[0032] Working principle: When connecting the compression elastic element to the vehicle suspension system, first insert one end of the slot 24 into the slot 231 on both sides of the base 21, so that half of the slot 24 is completely inside the slot 231. Then, insert the bolt 233 into the threaded hole 232 and rotate the bolt 233 to connect with the threaded hole 232. The bolt 233 passes through the through hole 234 on the outer surface of the slot 24, and the slot 24 is installed on the outer surface of the base 21. Then, insert the two inserts 33 at the bottom of the rectangular plate 32 into the two slots 31 at the top of the slot 24. When the inserts 33 are inserted into the slots 31, the two metal pieces 34 will bend inward at a certain angle. As the inserts 33 continue to go deeper, the two elastic metal pieces 34 will spring out and lock into the slots 31, fixing the position of the inserts 33 in the slots 31. The rectangular plate 32 is fixed to the top of the slot 24. The base 21 connects to the structural components of the suspension system. When the elastic component 1 is welded and installed, it will cause the round block 22 inside the base 21 to deflect in one direction when it is subjected to a large lateral force. The top of the round block 22 will abut against the bottom of the stop block 26 on one side of the base 21. When the force exceeds a certain limit, the round block 22 will rotate upward and push the stop block 26 to make the slider 25 slide on the inner wall of the groove block 24. This will cause the round rod 27 on one side of the stop block 26 to push the stop rod 28 to bend and break away from the stop block 26. Then the round block 22 will continue to rotate upward and the torque on the elastic component 1 will disappear. After the auxiliary device 2 is working, the rectangular plate 32 is pulled outward by pinching the two auxiliary grooves 35 at the top of the rectangular plate 32. This will cause the elastic metal sheet 34 on the outer surface of the two insert blocks 33 to deform and pull the insert blocks 33 out of the slot 31. The bolt 233 will be rotated to disengage the bolt 233 from the threaded hole 232. Then the groove block 24 will be pulled out of the slot 231 and removed to facilitate the re-welding of the rectangular rod.
