Description

Technical Field

[0001] This utility model belongs to the field of vehicle engineering technology, specifically a tool-free disassembly injection-molded automotive steering column maintenance structure. Background Technology

[0002] The steering column is an important component of the car steering system. Its function is to transmit the force of the driver turning the steering wheel to the steering gear, thereby realizing the vehicle's steering operation.

[0003] During the use of a car, the steering column may malfunction or require regular maintenance, which necessitates the disassembly and replacement of the steering column.

[0004] Traditional steering columns are typically secured to the vehicle body with numerous bolts. When maintenance is required, these bolts must be removed one by one using appropriate tools. However, in confined spaces such as under the passenger compartment, the limited space for tool operation increases the difficulty of disassembly. Furthermore, repeated bolt removal can lead to thread wear, making subsequent disassembly even more challenging.

[0005] Therefore, this utility model provides a tool-free disassembly injection-molded automotive steering column maintenance structure. Utility Model Content

[0006] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a tool-free disassembly injection-molded automotive steering column maintenance structure is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A tool-free disassembly injection-molded automotive steering column maintenance structure includes a steering column body; a quick-release assembly is installed in the middle of the steering column body; a steering shaft is detachably connected to the top of the quick-release assembly; a first placement groove is opened on the top of the steering shaft; a retaining groove is fixedly connected to the middle of the first placement groove; multiple equally spaced rubber limiting plates are fixedly connected to the middle of the retaining groove; a slot is opened near the middle of the rubber limiting plates in the retaining groove; a fixing bolt is threadedly connected to the middle of the slot; a cable outlet is opened near the middle of the steering column body near the steering shaft. Through the above structure, the combined use of the slot and the fixing bolt allows the clamping force of the rubber limiting plates to be evenly distributed on the outer circumference of the bottom connecting rod of the steering wheel. Simultaneously, the rubber limiting plates, made of rubber material, can fill the tiny gap between the bottom of the steering wheel and the rubber limiting plates, thus enhancing connection stability and buffering vibrations during steering operations.

[0008] Preferably, the quick-release assembly includes a base; the steering column body is fixedly connected to the base at the center away from the first placement slot; a first limiting block is fixedly connected to the top of the base; a second connecting block is fixedly connected to the bottom of the steering shaft near the first limiting block; a first connecting block is fixedly connected to the bottom of the second connecting block; two symmetrically arranged spring clips are slidably connected to the center of the first connecting block; a slider is slidably connected to the center of the first limiting block near the base; through the above structure, the continuous preload force generated by the cooperation of the spring clips and the first limiting block can offset the gap caused by vehicle vibration, ensuring that the steering shaft and the steering column body always remain connected, and the elastic potential energy of the spring clips can reduce rigid impact between components and problems such as abnormal noise caused by vibration loosening.

[0009] Preferably, a fixing seat is fixedly connected to the bottom of the steering column body; a second placement groove is provided in the middle of the fixing seat; a spring bolt is detachably connected to the middle of the second placement groove; a second limiting block is rotatably connected to the middle of the spring bolt; a universal bolt is fixedly connected to the bottom of the second limiting block; through the above structure, the cooperation of the spring bolt and the second limiting block can effectively provide a stable and lasting preload, increase the tightness of the connection between the steering column body and other parts, and reduce the difficulties in installation and maintenance of traditional connection methods.

[0010] Preferably, a third placement groove is provided in the middle of the steering column body near the steering shaft; a sealing cap is hinged to the middle of the steering column body near the third placement groove; a sponge sheet is detachably connected to the middle of the third placement groove; through the above structure, the sponge sheet can stably and evenly apply the absorbed lubricating oil to the surface of the steering shaft, ensuring that the entire circumference and the entire stroke of the column are in a stable lubrication state.

[0011] Preferably, two symmetrically arranged third limiting blocks are fixedly connected to the middle of the steering column body near the cable outlet; a third connecting block is detachably connected to the middle of the third limiting block; the above structure can effectively reduce problems such as poor contact and open circuit caused by loose wiring due to steering wobbling when the car is in motion.

[0012] Preferably, the steering column body is made of high-strength plastic; the steering shaft is made of aluminum alloy. Through the above structure, not only can the driver's injury be reduced, but the overall weight of the vehicle can also be reduced, and fuel efficiency and handling can be improved.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The tool-free disassembly injection-molded automotive steering column maintenance structure of this utility model, through the cooperation of the groove and the fixing bolt, can make the clamping force of the rubber limiting plate evenly distributed on the outer circumference of the bottom connecting rod of the steering wheel. At the same time, the rubber limiting plate made of rubber material can fill the tiny gap between the bottom of the steering wheel and the rubber limiting plate, which not only enhances the connection stability, but also buffers the vibration during steering operation.

[0015] 2. The tool-free disassembly injection-molded automotive steering column maintenance structure of this utility model can offset the gaps caused by vehicle vibration through the continuous pre-tightening force brought about by the cooperation of the spring clip and the first limiting block, ensuring that the steering shaft and the steering column body always remain connected. The elastic potential energy of the spring clip can reduce rigid impact between components and problems such as abnormal noise caused by vibration and loosening. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5 As shown in the embodiment of this utility model, a tool-free disassembly injection-molded automotive steering column maintenance structure includes a steering column body 1; a quick-release assembly 13 is installed in the middle of the steering column body 1; a steering shaft 12 is detachably connected to the top of the quick-release assembly 13; a first placement groove 14 is provided on the top of the steering shaft 12; a retaining groove 15 is fixedly connected to the middle of the first placement groove 14; a plurality of equally spaced rubber limiting plates 16 are fixedly connected to the middle of the retaining groove 15; a slot 17 is provided in the middle of the retaining groove 15 near the rubber limiting plates 16; a fixing bolt 18 is threadedly connected to the middle of the slot 17; a cable outlet 19 is provided in the middle of the steering column body 1 near the steering shaft 12; during operation, the quick-release assembly 13 is used to connect the steering column body 1 and the steering shaft 12. After fixing, place the connecting rod at the bottom of the steering wheel in the middle of the rubber limiting plate 16, and then turn the fixing bolt 18 clockwise. Since the slot 17 and the fixing bolt 18 are threaded, the fixing bolt 18 will continuously descend. As it descends, the bottom of the fixing bolt 18 will contact the rubber limiting plate 16, causing the rubber limiting plate 16 to converge towards the center. This connects and fixes the steering wheel to the steering shaft 12. Through the above structure, the cooperation of the slot 17 and the fixing bolt 18 can make the clamping force of the rubber limiting plate 16 evenly distributed on the outer circumference of the connecting rod at the bottom of the steering wheel. At the same time, the rubber limiting plate 16 can fill the small gap between the bottom of the steering wheel and the rubber limiting plate 16, which not only enhances the connection stability but also buffers the vibration during steering operation.

[0027] like Figures 1 to 3As shown, the quick-release assembly 13 includes a base 2; the base 2 is fixedly connected to the center of the steering column body 1 away from the first placement groove 14; a first limiting block 24 is fixedly connected to the top of the base 2; a second connecting block 25 is fixedly connected to the bottom of the steering shaft 12 near the first limiting block 24; a first connecting block 21 is fixedly connected to the bottom of the second connecting block 25; two symmetrically arranged spring clips 22 are slidably connected to the center of the first connecting block 21; a slider 23 is slidably connected to the center of the first limiting block 24 near the base 2; during operation, the steering shaft 12 is placed in the center of the steering column body 1 and slid downwards. The second connecting block 25 and the first connecting block 21 at the bottom of the steering shaft 12 will also move downwards synchronously. When the spring clips 22 contact the top of the first limiting block 24, the quick-release assembly 13 will release the steering shaft 12 due to the contact with the first limiting block 24. The resistance of contact pushes the spring clip 22 outward. When it slides to the middle of the first limiting block 24, the elastic element of the spring clip 22 releases some potential energy, pushing the spring clip 22 into the locking position, thus completing the fixation of the two. When disassembly is required, the first connecting block 21 continues to slide downward, so that the first limiting block 24 contacts the slider 23, which can drive the spring clip 22 out of the locking position of the first limiting block 24, completing the disassembly operation. Through the above structure, the continuous pre-tightening force brought about by the cooperation of the spring clip 22 and the first limiting block 24 can offset the gap caused by the vibration of the car, ensuring that the steering shaft 12 and the steering column body 1 always remain connected. The elastic potential energy of the spring clip 22 can reduce the rigid impact between components and the problem of abnormal noise caused by vibration and loosening.

[0028] like Figures 1 to 4 As shown, a fixing seat 3 is fixedly connected to the bottom of the steering column body 1; a second placement groove 31 is provided in the middle of the fixing seat 3; a spring bolt 32 is detachably connected to the middle of the second placement groove 31; a second limiting block 33 is rotatably connected to the middle of the spring bolt 32; a universal bolt 34 is fixedly connected to the bottom of the second limiting block 33; during operation, after the universal bolt 34 is fixed to the parts at the bottom of the car, the two are initially connected by the spring bolt 32, and then the second limiting block 33 is rotated. The second limiting block 33 can be used to precisely adjust the screw-in depth and tightening force of the spring bolt 32 to ensure that the steering column body 1 can fit tightly with the bottom parts and the connection is stable. Through the above structure, the cooperation of the spring bolt 32 and the second limiting block 33 can effectively provide a stable and lasting preload, increase the tightness of the connection between the steering column body 1 and other parts, and reduce the difficulties in installation and maintenance of traditional connection methods.

[0029] like Figures 4 to 5As shown, a third placement groove 41 is provided in the middle of the steering column body 1 near the steering shaft 12; a sealing cover 4 is hinged to the middle of the steering column body 1 near the third placement groove 41; a sponge sheet 42 is detachably connected to the middle of the third placement groove 41; during operation, the sponge sheet 42 can be placed in the middle of the third placement groove 41, and then the sealing cover 4 can be opened to inject oil into the sponge sheet 42, increasing the lubrication between the steering column body 1 and the steering shaft 12 and reducing the resistance during rotation. Through the above structure, the sponge sheet 42 can stably and evenly apply the absorbed lubricating oil to the surface of the steering shaft 12, ensuring that the entire circumference and the entire stroke of the column are in a stable lubrication state.

[0030] like Figures 4 to 5 As shown, two symmetrically arranged third limiting blocks 5 are fixedly connected to the middle of the steering column body 1 near the cable outlet 19; a third connecting block 51 is detachably connected to the middle of the third limiting block 5; during operation, the connecting wire is first placed in the middle of the third connecting block 51, and then the third limiting block 5 is placed in the middle of the third connecting block 51 to tighten the connecting wire, ensuring that it is always in the set position and maintaining a stable electrical connection. Through the above structure, problems such as poor contact and open circuit caused by loose wiring due to steering wobbling when the car is in motion can be effectively reduced.

[0031] like Figure 1 As shown in the figure, the steering column body 1 is made of high-strength plastic; the steering shaft 12 is made of aluminum alloy. During operation, the steering column body 1 can absorb collision energy through the deformation of the material itself, playing a buffering role. The steering shaft 12 can improve its thermal conductivity through the material, which helps to dissipate heat. Through the above structure, not only can the driver's injury be reduced, but the overall weight of the vehicle can also be reduced, and fuel efficiency and handling can be improved.

[0032] like Figure 3 As shown, the middle part of the steering column body 1 is coated with polytetrafluoroethylene. During operation, this material can greatly reduce the friction between the steering column body 1 and the base 2, making the steering operation smoother. Through the above structure, the mechanical resistance of the steering system can be significantly reduced and the steering efficiency can be improved.

[0033] During operation, after fixing the universal bolt 34 to the parts on the bottom of the car, the two are initially connected using the spring bolt 32. Then, the second limiting block 33 is rotated. The second limiting block 33 can be used to precisely adjust the screw-in depth and tightening force of the spring bolt 32, ensuring that the steering column body 1 can fit tightly and securely with the bottom parts. The steering shaft 12 is placed in the middle of the steering column body 1 and slid downwards. The second connecting block 25 and the first connecting block 21 at the bottom of the steering shaft 12 will also move downwards synchronously. When the spring clip 22 contacts the top of the first limiting block 24, the contact resistance will push the spring clip 22 outwards. When it slides to the middle of the first limiting block 24, the elastic element of the spring clip 22 releases some potential energy, pushing the spring clip 22 into the locking position, completing the fixation of the two. When disassembly is required, the first connecting block 21 is slid downwards to make the first limiting block 24 contact the slider 23, which will drive the spring clip 22 out of the locking position of the first limiting block 24, completing the disassembly operation. The universal bolt 34 is then removed. 4. After fixing the parts to the bottom of the car, use the spring bolt 32 to initially connect the two. Then rotate the second limit block 33. The second limit block 33 can be used to precisely adjust the screw depth and tightening force of the spring bolt 32 to ensure that the steering column body 1 can fit tightly with the bottom parts and be firmly connected. The sponge 42 can be placed in the middle of the third placement groove 41. Then open the sealing cover 4 and inject oil into the sponge 42 to increase the lubrication between the steering column body 1 and the steering shaft 12 and reduce the resistance during rotation. First, place the connecting wire in the middle of the third connecting block 51, and then place the third limit block 5 in the middle of the third connecting block 51 to tighten the connecting wire and ensure that it is always in the set position to maintain a stable electrical connection. The steering column body 1 can absorb the collision energy through the deformation of this material itself, which plays a buffer role. The steering shaft 12 can improve its thermal conductivity through this material, which helps to dissipate heat. This material can greatly reduce the friction between the steering column body 1 and the base 2, making the steering operation smoother.
