Technical Field

[0001] This utility model relates to the field of steering gear housing technology, specifically to an automotive aluminum alloy steering gear housing structure. Background Technology

[0002] As a core actuator of the automotive chassis system, the steering gear plays a crucial role in translating the driver's steering inputs into wheel steering motions. The steering gear housing, as the fundamental load-bearing structure of the steering gear, directly determines the stability, reliability, and steering precision of the steering system, exerting an irreplaceable influence on overall vehicle safety and handling comfort. Throughout the century-long history of the automotive industry, the design and manufacturing technology of steering gear housings has continuously evolved in response to the upgrading of vehicle performance requirements, advancements in materials science, and innovations in processing techniques.

[0003] In the existing technology, the aluminum alloy steering gear housing structure of automobiles is installed at the bottom of the vehicle floor. If it encounters a protrusion, it is easy to cause damage to the aluminum alloy steering gear housing structure. Furthermore, since such impacts often do not have good force dissipation, it may further damage the aluminum alloy steering gear.

[0004] A search revealed a steering gear housing disclosed in Chinese patent literature (Publication No.: CN212738260U). This application relates to a steering gear housing, which includes a main body in the shape of a cylinder. A first mounting portion and a second mounting portion are respectively provided at both ends of the main body. Multiple reinforcing ribs are provided on the main body, with the length direction of the reinforcing ribs aligned with the axial direction of the main body. The multiple reinforcing ribs are evenly distributed circumferentially along the main body. This application improves the structural strength of the steering gear housing and extends its service life, but it still has the following drawbacks: While the aforementioned steering gear housing achieves the effect of improving the structural strength of the steering gear housing and extending its service life, it still has the problem that, because it is installed at the bottom of the vehicle floor, it is prone to damage to the structure of the automotive aluminum alloy steering gear housing if it encounters a protrusion. Furthermore, since such impacts often do not have good force dissipation, it may further damage the automotive aluminum alloy steering gear. Utility Model Content

[0005] The purpose of this utility model is to provide an automotive aluminum alloy steering gear housing structure to solve the problems mentioned in the background art, which are that the automotive aluminum alloy steering gear housing structure is easily damaged by protrusions when it is installed at the bottom of the vehicle floor, and that such impacts often do not have good force dissipation, which may further damage the automotive aluminum alloy steering gear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive aluminum alloy steering gear housing structure, comprising an automotive aluminum alloy steering gear casting housing, an installation port provided at the top of the automotive aluminum alloy steering gear casting housing, sealing components installed on both sides of the installation port, a connecting plate installed on the bottom outer wall of the automotive aluminum alloy steering gear casting housing, limit blocks installed at equal intervals at the bottom of the connecting plate, installation cavities symmetrically opened at the bottom of each limit block, guide sleeves installed inside each installation cavity, connecting springs installed at the top of each guide sleeve, guide rods installed at the bottom of each connecting spring, the bottom of the guide rods connected to the top of the protective plate, and second balloons installed at equal intervals at the bottom of the connecting plate.

[0007] Preferably, the outer wall of the aluminum alloy steering gear casting housing is provided with first reinforcing ribs at equal intervals, and second reinforcing ribs are provided at equal intervals between the first reinforcing ribs.

[0008] Preferably, a first mounting tube is provided at one end of the cast housing of the automotive aluminum alloy steering gear, and a second mounting tube is provided at the other end of the cast housing of the automotive aluminum alloy steering gear.

[0009] Preferably, a third mounting tube is provided at the top end of the automotive aluminum alloy steering gear casting housing near the second mounting tube, and a fourth mounting tube is provided at the front end of the automotive aluminum alloy steering gear casting housing near the second mounting tube.

[0010] Preferably, the installation ports are installed at the top of the corresponding first and second installation tubes.

[0011] Preferably, the sealing assembly includes at least a connecting cover, a mounting ring, and a first balloon. The connecting cover is installed on both outer walls of the mounting port, the mounting ring is installed on one end of the connecting cover, the first balloon is installed on the inner wall of the mounting ring, and the silicone anti-slip pad is installed on the inner wall of the first balloon.

[0012] Preferably, a flexible cover is mounted on the end of the mounting ring away from the connecting cover via a connecting piece, and an elastic band is mounted on the end of the flexible cover away from the connecting piece.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a first reinforcing rib, a second reinforcing rib, and other structures, effectively improves the overall structural strength of the shell, enhances the load-bearing capacity and stability of the steering gear shell, and extends the service life of the steering gear shell. At the same time, the selection of aluminum alloy material not only ensures structural strength but also takes into account the need for lightweighting, which is in line with the development trend of the automotive industry to upgrade the performance of components.

[0014] 2. This utility model addresses the problem of the housing being easily impacted by protrusions. The protective plate at the bottom of the structure can directly absorb external impacts. Through the movable compression of the connecting spring within the guide sleeve, the initial force relief and buffering are achieved. The protective plate then compresses the second balloon of the inflatable structure to form a secondary force relief. This dual buffering design can effectively absorb impact energy and prevent damage to the housing and internal steering gear due to impact. This multi-level protection layout significantly improves the impact resistance of the housing, ensuring the stability of the steering system and the driving safety of the entire vehicle.

[0015] 3. This utility model effectively enhances the fixing effect of the installation components through the first balloon and silicone anti-slip pad. The flexible cover and elastic band can reduce the intrusion of air and liquid, avoid corrosion of the connection end, and further ensure the installation stability and overall service life. This improves the practicality and the service life of the structure. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example 1 Please see Figure 1-4This utility model provides a structure for an aluminum alloy steering gear housing, including an aluminum alloy steering gear casting housing 1. The outer side wall of the aluminum alloy steering gear casting housing 1 is welded with first reinforcing ribs 2 at equal intervals, while the bottom outer wall of the aluminum alloy steering gear casting housing 1 is not equipped with first reinforcing ribs 2. Second reinforcing ribs 3 are welded at equal intervals between the first reinforcing ribs 2. A first mounting tube 4 is provided at one end of the aluminum alloy steering gear casting housing 1, and a second mounting tube 5 is provided at the other end of the aluminum alloy steering gear casting housing 1. A third mounting tube 6 is provided at the top end of the aluminum alloy steering gear casting housing 1 near the second mounting tube 5, and a fourth mounting tube 7 is provided at the front end of the aluminum alloy steering gear casting housing 1 near the second mounting tube 5.

[0020] During use, the first reinforcing rib 2 and the second reinforcing rib 3 are welded to the outside of the automotive aluminum alloy steering gear casting housing 1, thereby effectively improving the strength of the automotive aluminum alloy steering gear casting housing 1. The first mounting tube 4, the second mounting tube 5, the third mounting tube 6 and the fourth mounting tube 7 together with the automotive aluminum alloy steering gear casting housing 1 form the main body and are used to install the steering gear.

[0021] The top ends of the first mounting tube 4 and the second mounting tube 5 are both welded with mounting ports 8. The outer walls of both ends of the mounting ports 8 are threaded, and sealing components are threadedly connected to the outer walls of both ends of the mounting ports 8. The sealing components include a connecting cover 9, a mounting ring 10, and a first balloon 11. The outer walls of both ends of the mounting ports 8 are threadedly connected with the connecting cover 9. The inner side wall of the connecting cover 9 is threaded, and a mounting ring 10 is fixedly connected to one end of the connecting cover 9. The inner side wall of the mounting ring 10 is fixedly connected with a first balloon 11 with a circular structure. The first balloon 11 is an inflatable structure. A silicone anti-slip pad 12 is fixedly connected to the inner side wall of the first balloon 11. A connecting piece 13 is fixedly connected to the outer wall of the mounting ring 10 away from the connecting cover 9. A flexible cover 14 is installed on the mounting ring 10 through the connecting piece 13. An elastic band 15 is installed on the end of the flexible cover 14 away from the connecting piece 13.

[0022] During use, the entire device and steering gear are installed in the designated area through the installation port 8 as the installation medium. During installation, the mounting component passes through the installation ring 10. After the mounting component is connected and fixed to the installation port 8, the inner wall of the installation ring 10 is threaded to the outer wall of the installation port 8, so that the first balloon 11 and the silicone anti-slip pad 12 wrap around the outer wall of the mounting component. This seals the port of the installation port 8 that is inserted into the mounting component and improves the stability of the mounting component by using the first balloon 11 and the silicone anti-slip pad 12. At the same time, the elastic band 15 fits against the outer wall of the mounting component, and the flexible cover 14 is also placed on the outer wall of the mounting component to reduce the entry of air and liquid, which can lead to corrosion of the connection end. This improves practicality and stability.

[0023] A connecting plate 16 is welded and fixedly connected to the bottom outer wall of the aluminum alloy steering gear casting housing 1. Limiting blocks 17 are fixedly connected at equal intervals at the bottom of the connecting plate 16. A protective plate 18 is provided below the limiting block 17. Guide sleeve rods 19 are fixedly connected at equal intervals symmetrically to the top of the protective plate 18. The top of the guide sleeve rod 19 is vertically and movably connected to the bottom of the guide sleeve 21. A connecting spring 20 is fixedly connected to the top of the guide sleeve 21. The bottom of the connecting spring 20 is fixedly connected to the top of the guide sleeve rod 19. The guide sleeve 21 is fixedly connected to the inside of the mounting cavity, and the mounting cavity is opened at the bottom of the limiting block 17. A second balloon 22 is fixedly connected to the bottom of the connecting plate 16 between the limiting blocks 17. The second balloon 22 is an inflatable structure.

[0024] During use, the protective plate 18 is positioned at the bottom of the structure, allowing it to directly contact the impact. When the protective plate 18 is impacted, it moves vertically upward in conjunction with the guide sleeve 19, compressing the connecting spring 20 for initial stress relief. Additionally, the top of the protective plate 18 compresses the second balloon 22, which, being an inflatable structure, provides secondary stress relief. This method effectively reduces external impacts, improving the device's practicality and extending the service life of the automotive aluminum alloy steering gear casting housing 1.

[0025] The specific usage process in this embodiment is as follows: First, the first reinforcing rib 2 and the second reinforcing rib 3 are welded to the outside of the automotive aluminum alloy steering gear casting housing 1, thereby effectively improving the service strength of the automotive aluminum alloy steering gear casting housing 1. Secondly, the main body is formed by the first mounting tube 4, the second mounting tube 5, the third mounting tube 6 and the fourth mounting tube 7 and the automotive aluminum alloy steering gear casting housing 1, and is used to install the steering gear; Subsequently, using the installation port 8 as the installation medium, the entire device and the steering gear are installed to the designated area, and the inner wall of the installation ring 10 is threadedly connected to the outer wall of the installation port 8, so that the first balloon 11 and the silicone anti-slip pad 12 are wrapped around the outer wall of the mounting component. This seals the port of the installation port 8 that is inserted into the mounting component, and improves the stability of the mounting component by the first balloon 11 and the silicone anti-slip pad 12. At the same time, the elastic band 15 fits against the outer wall of the mounting component, and the flexible cover 14 is also placed on the outer wall of the mounting component to reduce the entry of air and liquid. Finally, the protective plate 18 is brought into direct contact with the impact. When the protective plate 18 is impacted, it moves vertically upward in conjunction with the guide sleeve 19, causing the guide sleeve 19 to compress the connecting spring 20, thereby initially releasing the force. Additionally, the top of the protective plate 18 squeezes the second balloon 22. Since the second balloon 22 is an inflatable structure, it releases the force a second time. This completes the use of an automotive aluminum alloy steering gear housing structure.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
