DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] Please refer to Figures 1 to 6 A new energy automobile aluminum alloy hollow control arm, comprising a control arm body 1, two groups of connecting parts 2 are fixedly installed on the top of the control arm body 1,

[0031] Further comprising:

[0032] The protection assembly comprises two groups of protection frames 3 arranged above the control arm body 1, the two groups of protection frames 3 are arranged at the outer sides of the adjacent connecting parts 2 respectively, the outer sides of the two groups of connecting parts 2 are sleeved with rubber sleeves 4, the two groups of rubber sleeves 4 are fixedly installed in the inner cavities of the adjacent protection frames 3, the inner cavity walls of the two groups of protection frames 3 are uniformly provided with grooves 5, the inner cavities of each group of grooves 5 are slidingly installed with fixing blocks 6, the fixing blocks 6 are fixedly installed between the inner cavity walls of the adjacent grooves 5, the outer walls of the two groups of rubber sleeves 4 are uniformly provided with extrusion grooves 8 matched with the adjacent fixing blocks 6, one end of each group of fixing blocks 6 away from the adjacent extension springs 7 is in contact with the inner cavities of the adjacent extrusion grooves 8, and the outer sides of the two groups of protection frames 3 are provided with protection assemblies.

[0033] The protection assembly comprises two groups of protection frames 3 arranged above the control arm body 1, the two groups of protection frames 3 are arranged at the outer sides of the adjacent connecting parts 2 respectively, the outer sides of the two groups of connecting parts 2 are sleeved with rubber sleeves 4, the two groups of rubber sleeves 4 are fixedly installed in the inner cavities of the adjacent protection frames 3, the inner cavity walls of the two groups of protection frames 3 are uniformly provided with grooves 5, the inner cavities of each group of grooves 5 are slidingly installed with fixing blocks 6, the fixing blocks 6 are fixedly installed between the inner cavity walls of the adjacent grooves 5, the outer walls of the two groups of rubber sleeves 4 are uniformly provided with extrusion grooves 8 matched with the adjacent fixing blocks 6, one end of each group of fixing blocks 6 away from the adjacent extension springs 7 is in contact with the inner cavities of the adjacent extrusion grooves 8, and the outer sides of the two groups of protection frames 3 are provided with protection assemblies.

[0034] First, before the control arm body 1 is transported, the rubber sleeve 4 is sleeved on the side wall of the connecting part 2, and the initial state of the extension spring 7 is restored to push the fixed block 6 to move inwards by extruding the inner cavity of the extrusion groove 8 and extruding the side wall of the rubber sleeve 4. At this time, the position of the inner cavity wall of the rubber sleeve 4 extruded by the fixed block 6 will be smaller than the size of the bottom circumference of the connecting part 2. When the rubber sleeve 4 is sleeved on the outside of the connecting part 2, the position of the rubber sleeve 4 extruded by the fixed block 6 will contact the inclined wall of the connecting part 2. By pushing the protective frame 3 downwards by the elastic air bag sleeve 12, the position of the rubber sleeve 4 extruded by the fixed block 6 will move downwards along the inclined wall of the connecting part 2 to the vertical side wall. At this time, the connecting part 2 will slide outward in the inner cavity of the slot 5 by extruding the fixed block 6 and extruding the extension spring 7 through the rubber sleeve 4. The rubber sleeve 4 can be completely sleeved on the outside of the connecting part 2. By the elastic force of the extension spring 7, the fixed block 6 can extrude and fix the outer wall of the connecting part 2 through the rubber sleeve 4. The rubber sleeve 4 can be easily sleeved on the outside of the connecting part 2, which improves the stability of the rubber sleeve 4 and prevents it from falling off, effectively improving the work efficiency. During transportation, the impact force on the side wall can be buffered by the elastic air bag sleeve 12. When there is an impact force above, the impact force above will push the top seat 10 downwards and extrude the return spring 11. The buffering of the top seat 10 is realized by the setting of the return spring 11, which plays a role in multiple protection, effectively improves the protection effect of the connecting part 2, and avoids the simple wrapping in the past, which causes the connecting part 2 to be easily deformed or damaged during road bumps. It can effectively reduce the excessive impact force on the connecting part 2, effectively protect the rubber material and the threads on the connecting part 2, and avoid unnecessary losses.

[0035] The elastic air bag sleeve 12 is provided with a one-way valve at the outlet end and the inlet end, and each group of exhaust pipes 19 is provided with a one-way valve, which realizes one-way air inlet and outlet. When the elastic air bag sleeve 12 is extruded by external force, the gas in the inner cavity of the elastic air bag sleeve 12 will be extruded and discharged into the through hole 16 through the outlet end, the gas in the through hole 16 will be discharged into the gas storage cavity 15, and the gas in the inner cavity of the gas storage cavity 15 will be discharged into the elastic ring 14 through the exhaust pipe 19. When the pressure applied to the elastic air bag sleeve 12 is removed, the elastic air bag sleeve 12 will suck the gas outside through the inlet end to restore the initial state. At this time, the elastic air bag sleeve 12 will supply gas to the inner cavity of the elastic ring 14 when it is extruded, which can increase the pressure in the inner cavity of the elastic ring 14. The increase of the pressure in the inner cavity of the elastic ring 14 will cause the elastic ring 14 to expand. Through the setting of the circular frame 13, the expansion of the elastic ring 14 in the circular frame 13 will extrude the connecting part 2 through the elastic ring 14, which can fix the rubber sleeve 4 on the connecting part 2, further realizing the fixing and protection effect, avoiding the movement of the connecting part 2 during transportation and causing friction with other objects, thereby avoiding wear and damage, and effectively improving the quality of the connecting part 2.

[0036] As Figure 2 , Figure 3 and Figure 5 shown, the two groups of top seats 10 and the adjacent protective frames 3 are provided with cavities 25, the top of the two groups of protective frames 3 is provided with air inlet holes 17, the top of the two groups of air inlet holes 17 is in communication with the inner cavity of the adjacent cavity 25, the other end of the two groups of air inlet holes 17 is in communication with the inner cavity of the adjacent through hole 16, the two groups of top seats 10 are provided with air suction holes 18 in communication with the inner cavity of the adjacent cavity 25, and the other end of the two groups of air suction holes 18 is in communication with the outside.

[0037] The inner cavity of the air suction hole 18 is provided with a one-way valve, when the top of the top seat 10 is pressed, the top seat 10 will be pressed downward and extrude the reset spring 11, the downward movement of the top seat 10 will extrude the gas in the cavity 25 into the air inlet hole 17, the gas in the air inlet hole 17 will be discharged into the inner cavity of the gas storage cavity 15 through the through hole 16, and the gas in the inner cavity of the gas storage cavity 15 will be discharged into the inner cavity of the elastic ring 14 through the exhaust pipe 19, when there is no pressure on the top seat 10, under the action of the reset spring 11, the reset spring 11 returns to the initial state and pushes the top seat 10 upward to the initial position, so that the cavity 25 can suck the gas outside, at this time, when the top seat 10 is pressed, it will supply gas to the inner cavity of the elastic ring 14, which can further supply gas and effectively improve the stability of clamping, thereby effectively improving the protection effect of the connecting part 2, avoiding damage to the threads on the connecting part 2 and improving the stability of the connecting part 2 in transportation.

[0038] As Figure 2 , Figure 3 and Figure 5 shown, the two groups of rubber sleeves 4 and the protective frames 3 are provided with through holes 20, the inner cavities of the two groups of through holes 20 are slidably installed with pull rods 21, the two groups of pull rods 21 are slidably installed with the adjacent top seats 10, the rod walls of the two groups of pull rods 21 are fixedly installed with limit plates 22, and the two groups of limit plates 22 are in contact with the top of the adjacent protective frame 3.

[0039] The two groups of protective frames 3 and the adjacent circular frames 13 are provided with air outlet holes 23, the top of the two groups of air outlet holes 23 is in communication with the inner cavity of the adjacent through hole 20, and the side of each group of elastic ring 14 close to the adjacent air outlet hole 23 is fixedly installed with an air outlet pipe 24, and the other end of each group of air outlet pipe 24 is in communication with the inner cavity of the adjacent circular frame 13 and the air outlet hole 23.

[0040] When the pressure in the elastic ring 14 increases, the gas in the inner cavity of the elastic ring 14 will be discharged into the air outlet hole 23 through the air outlet pipe 24. In the initial state, the pull rod 21 is slidingly installed in the inner cavity of the through hole 20 and seals the inner cavity of the through hole 20, so that the gas in the air outlet hole 23 cannot be discharged into the through hole 20. When it is necessary to remove the rubber sleeve 4 from the connecting part 2, the pull rod 21 is pulled upward to move upward, and the pull rod 21 moves upward in the inner cavity of the through hole 20. When the limiting plate 22 driven by the pull rod 21 moves upward and contacts the bottom of the top seat 10, the bottom end of the through hole 20 moves to the upper side of the top end of the air outlet hole 23, and the pull rod 21 does not move out of the through hole 20, and the upper half of the inner cavity of the through hole 20 is sealed. The limiting plate 22 can limit the movement of the pull rod 21. At this time, the air outlet hole 23 is in communication with the inner cavity of the through hole 20. Under the action of the elastic ring 14, the elastic ring 14 returns to the initial state and expands to contract, so that the gas in the inner cavity of the elastic ring 14 is discharged into the air outlet hole 23 through the air outlet pipe 24. The gas in the air outlet hole 23 is discharged into the space between the rubber sleeve 4 and the connecting part 2 through the through hole 20, and then the protective frame 3 is pulled upward by the elastic air bag sleeve 12, so that the rubber sleeve 4 is removed from the side wall of the connecting part 2. At the same time, under the cooperation of the air blowing into the inner cavity of the rubber sleeve 4 through the through hole 20, the efficiency of removing the rubber sleeve 4 can be effectively improved, which is convenient to disassemble, can effectively reduce the manpower, and can effectively improve the work efficiency.

[0041] As shown in Figure 5 and Figure 6 , two groups of elastic air bag sleeves 12 are fixedly installed on one side close to the adjacent slot 5, and the other end of each group of connecting pipes 26 is in communication with the inner cavity of the adjacent protective frame 3 and the slot 5.

[0042] The connecting pipe 26 is provided with a one-way valve. When the elastic air bag sleeve 12 is extruded by external force, the gas in the inner cavity of the elastic air bag sleeve 12 is also discharged into the inner cavity of the slot 5 through the connecting pipe 26, so that the pressure in the inner cavity of the slot 5 is increased, and a pushing force is applied to the fixed block 6, further improving the extrusion force of the fixed block 6 on the rubber sleeve 4 through the extrusion slot 8, effectively improving the clamping and fixing effect of the rubber sleeve 4 on the outer wall of the connecting part 2, effectively improving the stability of the rubber sleeve 4, and improving the protection of the connecting part 2 while avoiding the movement of the rubber sleeve 4 and the friction therebetween, thereby effectively improving the quality of the connecting part 2.

[0043] As shown in Figures 3 to 6 , the bottom of each of the two groups of protective frames 3 is fixedly installed with a sealing ring 28, and the inner cavity bottom wall of each group of slots 5 is provided with an air outlet hole 27, and the other end of each group of air outlet holes 27 is in communication with the inner cavity of the adjacent sealing ring 28, and the two groups of sealing rings 28 are in contact with the top of the control arm body 1.

[0044] The anti-skid lines 9 are arranged on the side of each group of fixing blocks 6 away from the adjacent telescopic springs 7, and are also arranged on the inner cavity wall of the adjacent rubber sleeves 4 and in contact with the adjacent connecting parts 2.

[0045] The initial state of each group of telescopic springs 7 is compressed.

[0046] Each group of pull rods 21 is sealingly and slidably installed in the inner cavity of the adjacent through opening 20.

[0047] When the elastic air bag sleeve 12 is subjected to external force to extrude the gas in it through the connecting pipe 26 into the inner cavity of the slot 5, the gas in the inner cavity of the slot 5 will be discharged into the inner cavity of the sealing ring 28 through the exhaust hole 27, so as to increase the pressure in the inner cavity of the sealing ring 28 and improve the sealing between the protective frame 3 and the control arm body 1, which can avoid the entry of dust and impurities into the space between the rubber sleeve 4 and the connecting part 2 during transportation and prevent the friction between the rubber sleeve 4 and the connecting part 2, thereby effectively improving the quality and service life of the connecting part 2. Through the arrangement of the anti-skid lines 9, when the fixing blocks 6 extrude the rubber sleeves 4 through the inner cavities of the extrusion grooves 8, the positions of the anti-skid lines 9 on the rubber sleeves 4 will be pressed against the outer wall of the connecting part 2, which can effectively increase the friction between the rubber sleeve 4 and the connecting part 2 and prevent the rubber sleeve 4 from moving on the outer wall of the connecting part 2, thereby effectively improving the protection effect on the connecting part 2.

[0048] Working principle: first, before transporting the control arm body 1, the worker sets the rubber sleeve 4 on the connecting part 2, pushes the protective frame 3 downward through the elastic air bag sleeve 12, and through the cooperation of the fixing blocks 6 and the telescopic springs 7, the rubber sleeve 4 can be extruded to clamp and fix the outer wall of the connecting part 2 through the anti-skid lines 9. The arrangement of the elastic air bag sleeve 12 can achieve the protection of the outer side of the connecting part 2, and the cooperation of the top seat 10 and the return spring 11 can achieve the buffering of the impact force on the upper side. When the elastic air bag sleeve 12 and the top seat 10 are extruded by the impact force, the inner cavity of the elastic ring 14 will be supplied with gas through the through hole 16 and the air inlet hole 17, respectively, to increase the pressure in the inner cavity of the elastic ring 14, further clamp and fix the connecting part 2 through the rubber sleeve 4. When the elastic air bag sleeve 12 is extruded, the inner cavity of the slot 5 will be supplied with gas through the connecting pipe 26, to increase the pressure in the inner cavity of the slot 5, further increase the clamping force of the fixing blocks 6, and the gas in the inner cavity of the slot 5 will be supplied into the inner cavity of the sealing ring 28 through the exhaust hole 27, to increase the pressure in the inner cavity of the sealing ring 28 and improve the sealing between the protective frame 3 and the control arm body 1. When the rubber sleeve 4 needs to be removed, pull the pull rod 21 upward, the gas in the inner cavity of the elastic ring 14 will be discharged into the space between the rubber sleeve 4 and the connecting part 2, and at the same time, the protective frame 3 is pulled upward by the elastic air bag sleeve 12 to move the rubber sleeve 4 out of the side wall of the connecting part 2. With the cooperation of the through opening 20 blowing gas between the rubber sleeve 4 and the connecting part 2, the rubber sleeve 4 can be easily removed.

[0049] The above description is only the preferred embodiment of the present application; the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the improvement concept of the present application within the technical scope disclosed by the present application, which should be covered in the protection scope of the present application.
