Description

Technical Field

[0001] This utility model relates to the field of die casting technology, specifically to a thin-walled, multi-ribbed, integrated lightweight automotive steering gear die casting. Background Technology

[0002] The function of a car steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly by reducing speed and increasing torque) and then output them to the steering tie rod mechanism, thereby turning the car. Therefore, the steering gear is essentially a speed reduction transmission device. Existing steering gear die castings are mostly smooth sleeves, which have insufficient structural strength, are prone to deformation, and are relatively bulky, which can increase the overall weight of the car. In addition, they are mostly fixed to the car body with screws, which makes disassembly inconvenient. In order to improve the above problems, a thin-walled, multi-ribbed, integrated, lightweight automotive steering gear die casting is proposed.

[0003] For example, the new energy vehicle steering gear die casting part disclosed in the authorization announcement number CN219447107U includes a die casting tube and a protective component disposed outside the die casting tube. The protective component has two components, which are evenly installed on the outer surface of the die casting tube. The protective component includes a rubber pad disposed on the outer surface of the die casting tube. Several shock absorbers are fixedly connected to the outer surface of the rubber pad. One end of the shock absorber is fixedly connected to a shell.

[0004] Although it achieves the ability to block part of the impact force through the outer shell, the shock absorber absorbs the vibration force generated by the impact, and prevents the die-cast tube from being vibrated, the rubber pad further reduces the impact force on the die-cast tube, thereby greatly reducing or even eliminating the impact force transmitted to the die-cast tube, thus preventing damage to the fragile parts of the die-cast tube, avoiding deformation of the die-cast tube, and reducing cost losses.

[0005] However, this does not solve the problem that existing die-cast parts are not conducive to quick plug-in installation during use, nor to the heat dissipation of the steering gear, which affects the convenience of disassembly and assembly and the heat dissipation effect. Utility Model Content

[0006] The purpose of this invention is to provide a thin-walled, multi-ribbed, integrated lightweight automotive steering gear die-casting part to solve the problems mentioned in the background art, such as the difficulty in quick insertion and installation of die-casting parts, the disadvantage in heat conduction and dissipation of the steering gear, and the impact on the convenience of disassembly and assembly and the heat dissipation effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a thin-walled, multi-ribbed, integrated lightweight automotive steering gear die-casting part, comprising an integrated frame and connecting pipes. Connecting pipes are provided on both sides of the integrated frame. Three sets of equally spaced external limiting grooves are provided on the outer surface of each connecting pipe. Connecting blocks are provided on the side walls of each connecting pipe. Insertion seats are provided on the outer surfaces of each connecting block. Mounting brackets are symmetrically arranged on the outer walls of each insertion seat. Insertion posts are provided on the side walls of each connecting block. Limiting rings are provided on the side walls of each insertion seat. Limiting posts are slidably arranged inside each limiting ring. Springs are provided on the surfaces of each limiting post, with both ends of the springs connected to the limiting post and the limiting ring, respectively. Insertion grooves are provided on the surfaces of each insertion post.

[0008] Preferably, the integrated frame has a transmission column inside, and transmission rods are provided at both ends of the transmission column. A gear is provided inside the integrated frame on one side of the transmission column, and the gear meshes with a rack. A transmission shaft is provided at the top of the gear.

[0009] Preferably, a rack is provided on one side of the transmission column, and a first inner limiting strip is provided on the other side of the transmission column.

[0010] Preferably, the inner wall of the connecting pipe is provided with multiple sets of reinforcing ribs at equal intervals, and the reinforcing ribs are fixedly connected to the connecting pipe.

[0011] Preferably, an inner limiting groove is provided on the inner wall of the connecting pipe on one side of the first inner limiting strip, and the first inner limiting strip is slidably connected to the inner limiting groove.

[0012] Preferably, each of the connecting pipes is provided with an outer protective shell, and the inner wall of the outer protective shell is provided with multiple sets of heat dissipation fins at equal intervals.

[0013] Preferably, a second inner limiting strip is provided on the inner wall of the outer protective shell on one side of the outer limiting groove, and the second inner limiting strip is slidably connected to the outer limiting groove.

[0014] Preferably, the outer wall of the outer protective shell is provided with heat dissipation threads, and the heat dissipation threads are fixedly connected to the outer protective shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the die-cast part not only realizes quick plug-in installation, which facilitates the heat conduction and dissipation of the steering gear, but also improves the convenience of disassembly and assembly and the heat dissipation effect.

[0016] (1) Install the plug-in socket on the vehicle body using the mounting bracket. Take the integrated frame and move the connecting pipe. Move the connecting block using the connecting pipe. Move the plug-in post using the connecting block and insert it into the plug-in socket. Move the limiting post inside the limiting ring using the plug-in post. Under the limiting engagement of the limiting ring, the limiting post squeezes the spring and causes the spring to deform. When the plug-in slot moves to the position of the limiting post, under the elastic engagement of the spring, the spring drives the limiting post to reset and insert it into the plug-in slot to fix the plug-in post inside the plug-in socket. This allows the integrated frame and connecting pipe to be installed in the vehicle body. Connect the transmission rod to the steering column and the transmission shaft to the steering wheel connecting shaft. Rotate the steering wheel. The steering wheel drives the transmission shaft and gear to rotate through the connecting shaft. The gear drives the transmission column to move through the rack and the transmission column drives the steering column to rotate through the transmission rod to achieve the function of adjusting the direction. This achieves quick plug-in installation and improves the convenience of disassembly and assembly.

[0017] (2) By taking out the outer protective shell, align the second inner limit strip with the outer limit groove, move the outer protective shell, and let the outer protective shell drive the second inner limit strip to slide inside the outer limit groove. Install the outer protective shell onto the outer wall of the connecting pipe, so that the heat dissipation fins are tightly attached to the outer wall of the connecting pipe. When the transmission rod is working, it will generate heat. After the heat is dissipated, it will be transferred to the surface of the connecting pipe. Under the heat exchange effect of the heat dissipation fins, the heat is conducted to the surface of the outer protective shell through the heat dissipation fins, and the heat is dissipated by the heat dissipation thread. Because the heat dissipation thread has a large contact area with the outside, it can dissipate the heat well, thereby cooling the inside of the steering gear, thus ensuring its working stability, extending its service life, achieving good heat conduction and heat dissipation inside the steering gear, and improving the heat dissipation effect.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-5 An embodiment of this utility model provides a thin-walled, multi-ribbed, integrated lightweight automotive steering gear die-casting part, including an integrated frame 1 and a connecting pipe 2. The integrated frame 1 is provided with connecting pipes 2 on both sides. The outer surface of the connecting pipe 2 is provided with three sets of equally spaced external limiting grooves 7. The side wall of the connecting pipe 2 is provided with connecting blocks 5. The outside of the connecting blocks 5 is provided with plug seats 4. The outer wall of the plug seats 4 is symmetrically provided with mounting brackets 6. The side wall of the connecting blocks 5 is provided with plug posts 17. The side wall of the plug seats 4 is provided with limiting rings 20. The inside of the limiting rings 20 is slidably provided with limiting posts 19. The surface of the limiting posts 19 is provided with springs 21, and the two ends of the springs 21 are respectively connected to the limiting posts 19 and the limiting rings 20. The surface of the plug posts 17 is provided with plug grooves 18.

[0026] The integrated frame 1 has a transmission column 8 inside, and transmission rods 9 are provided at both ends of the transmission column 8. A gear 11 is provided inside the integrated frame 1 on one side of the transmission column 8, and the gear 11 meshes with the rack 10. A transmission shaft 12 is provided at the top of the gear 11. A rack 10 is provided on one side of the transmission column 8, and a first inner limit bar 15 is provided on the other side of the transmission column 8.

[0027] Multiple sets of reinforcing ribs 14 with equal spacing are provided on the inner wall of the connecting pipe 2, and the reinforcing ribs 14 are fixedly connected to the connecting pipe 2;

[0028] An inner limiting groove 16 is provided on the inner wall of the connecting pipe 2 on one side of the first inner limiting strip 15, and the first inner limiting strip 15 is slidably connected to the inner limiting groove 16.

[0029] The connector 4 is mounted on the vehicle body via the mounting bracket 6. The integrated frame 1 is removed, and the integrated frame 1 moves the connecting pipe 2, which in turn moves the connecting block 5. The connecting block 5 then moves the connector pin 17, which is inserted into the connector 4. The connector pin 17 moves the limiting pin 19 outward within the limiting ring 20. Under the limiting action of the limiting ring 20, the limiting pin 19 compresses the spring 21, causing it to deform. When the connector slot 18 moves to the position of the limiting pin 19, the spring 21, under its elastic action, causes the limiting pin 19 to reset and insert into the connector slot 18, thus connecting the connector. The column 17 is fixed inside the plug-in seat 4, thereby installing the integrated frame 1 and the connecting pipe 2 in the vehicle body, connecting the transmission rod 9 to the steering column, and connecting the transmission shaft 12 to the steering wheel connecting shaft. When the steering wheel is rotated, the steering wheel drives the transmission shaft 12 and the gear 11 to rotate through the connecting shaft. Under the mutual meshing of the gear 11 and the rack 10, and the sliding cooperation between the first inner limit strip 15 and the inner limit groove 16, the gear 11 drives the transmission column 8 to move through the rack 10, and the transmission column 8 drives the steering column to rotate through the transmission rod 9, thereby realizing the function of adjusting the direction. This achieves quick plug-in installation and improves the convenience of disassembly and assembly.

[0030] All connecting pipes 2 are provided with an outer protective shell 13, and the inner wall of the outer protective shell 13 is provided with multiple sets of heat dissipation fins 22 at equal intervals.

[0031] A second inner limit strip 23 is provided on the inner wall of the outer protective shell 13 on one side of the outer limit groove 7, and the second inner limit strip 23 is slidably connected to the outer limit groove 7.

[0032] The outer wall of the outer protective shell 13 is provided with heat dissipation threads 3, and the heat dissipation threads 3 are fixedly connected to the outer protective shell 13.

[0033] Take out the outer protective shell 13, align the second inner limiting strip 23 with the outer limiting groove 7, move the outer protective shell 13 so that the second inner limiting strip 23 slides inside the outer limiting groove 7, install the outer protective shell 13 onto the outer wall of the connecting pipe 2 so that the heat dissipation fins 22 are tightly attached to the outer wall of the connecting pipe 2. When the transmission rod 9 is working, it will generate heat. After the heat is dissipated, it will be transferred to the surface of the connecting pipe 2. Under the heat exchange effect of the heat dissipation fins 22, the heat will be conducted to the surface of the outer protective shell 13 through the heat dissipation fins 22, and the heat will be dissipated by the heat dissipation thread 3. Because the heat dissipation thread 3 has a large contact area with the outside, it can dissipate the heat well, thereby cooling the inside of the steering gear, ensuring its working stability, extending its service life, achieving good heat conduction and heat dissipation inside the steering gear, and improving the heat dissipation effect.

[0034] Working principle: The connector 4 is installed on the vehicle body via the mounting bracket 6. The integrated frame 1 is removed, and the integrated frame 1 drives the connecting pipe 2 to move. The connecting pipe 2 drives the connecting block 5 to move, and the connecting block 5 drives the connector pin 17 to move and insert it into the connector 4. The connector pin 17 drives the limiting pin 19 to move outward inside the limiting ring 20. Under the limiting cooperation of the limiting ring 20, the limiting pin 19 compresses the spring 21 and causes the spring 21 to deform. When the connector slot 18 moves to the limiting pin... At position 19, under the elastic cooperation of spring 21, spring 21 drives the limiting post 19 to reset and insert into the inside of the insertion slot 18, thereby fixing the insertion post 17 inside the insertion seat 4. This allows the integrated frame 1 and connecting pipe 2 to be installed in the vehicle body, connecting the transmission rod 9 to the steering column, and connecting the transmission shaft 12 to the steering wheel connecting shaft. Rotating the steering wheel drives the transmission shaft 12 and gear 11 to rotate via the connecting shaft. Under the mutual meshing of gear 11 and rack 10... With the sliding engagement of the first inner limiting strip 15 and the inner limiting groove 16, the gear 11 drives the transmission column 8 to move through the rack 10, and the transmission column 8 drives the steering column to rotate through the transmission rod 9 to achieve the function of adjusting the direction. At the same time, the outer protective shell 13 is removed, the second inner limiting strip 23 is aligned with the outer limiting groove 7, and the outer protective shell 13 is moved. The outer protective shell 13 drives the second inner limiting strip 23 to slide inside the outer limiting groove 7, and the outer protective shell 13 is installed on the outer wall of the connecting pipe 2, so that the heat dissipation fins 22 are tightly attached to the outer wall of the connecting pipe 2. When the transmission rod 9 is working, it will generate heat. After the heat is dissipated, it is transferred to the surface of the connecting pipe 2. Under the heat exchange effect of the heat dissipation fins 22, the heat is conducted to the surface of the outer protective shell 13 through the heat dissipation fins 22, and the heat is dissipated by the heat dissipation thread 3. Because the heat dissipation thread 3 has a large contact area with the outside, it can dissipate the heat well, thereby cooling the inside of the steering gear and ensuring its working stability.
