Description

Technical Field

[0001] The utility model relates to the technical field of steering columns, in particular to a waterproof steering column. Background Art

[0002] The steering column is an important component in the steering system. It connects the steering wheel and the steering gear. Through the steering column, the driver can transfer torque to the steering gear, thereby realizing the steering function of the vehicle. The main types of steering columns include hydraulic power steering columns, electronically controlled hydraulic power steering columns and electric power steering columns. The vehicle will experience bumps during movement. For some vehicles with low chassis or large vehicles, the steering column is prone to rusting due to contact with water, so a protective structure for the steering column is required.

The utility model discloses a steering column sealing structure. During the adjustment of the steering column and the flipping of the vehicle body, the rubber sealing sleeve, the fixing plate and the front fender become a whole without relative movement between them, and the rubber sealing sleeve itself does not deform too much. This can improve the service life of the sealing structure, ensure the sealing performance of the vehicle body, and is beneficial to the sound insulation, noise reduction, dustproof and waterproof performance of the entire vehicle, thereby ensuring the safe use performance of the entire vehicle.

[0032] It can be understood that the provision of the anti-rust component 5 is conducive to rust-proofing the steering column, which is conducive to the stable use of the steering column, thereby facilitating the improvement of the overall service life.

[0033] It can also be understood that a universal joint 6 is fixed to the right side of the movable rod 4 , a connecting block 7 is movably connected to the inner side of the universal joint 6 , and a mounting component 8 is fixed to the right side of the connecting block 7 .

[0034] It should be noted that the provision of the universal joint 6 is conducive to achieving the steering function of the column and is conducive to overall stable use.

[0035] See also Figure 2In order to achieve waterproof treatment of the pipe column, the anti-rust component 5 in this embodiment includes a protective cylinder 501, a fixed block 502, a movable plate 503, an action block 504 and an oil supply component. The protective cylinder 501 is fixed to the outer side of the fixed cylinder 3, and the fixed block 502 is fixed to the top of the movable rod 4. A sliding opening is opened on the right side of the protective cylinder 501, and the movable rod 4 is slidably connected to the protective cylinder 501 through the sliding opening.

[0036] It should be noted that the provision of the sliding opening is conducive to the sliding of the movable rod 4, thereby facilitating the stable use of the entire structure, thereby facilitating the improvement of the stability of the use of the entire pipe string.

[0037] It should also be noted that the movable plate 503 is fixed to the top of the fixed block 502, and the movable plate 503 extends to the inner cavity of the protective tube 501. A sliding channel is provided on the inner cavity wall at the top of the protective tube 501. Sliding plates are fixed on the front and back sides of the movable plate 503. The sliding plates are slidably connected to the protective tube 501 through the sliding channels, and the action block 504 is fixed to the bottom of the movable plate 503.

[0038] The setting of the sliding channel and the sliding plate is conducive to the stable sliding of the movable plate 503 and the protective tube 501, thereby improving the stability of the movable plate 503, and further promoting the stable use of the action block 504 and the storage box 506, thereby improving the overall stability of use.

[0039] It can be seen that the oil supply assembly includes a grease box 505, a storage box 506 and a disassembly assembly 507. The grease box 505 is fixed to the right side of the fixed cylinder 3, the movable rod 4 is movably connected to the grease box 505, the top of the grease box 505 is fixed to the storage box 506, the storage box 506 extends to the outside of the protective cylinder 501, and the disassembly assembly 507 is fixed to the top of the protective cylinder 501.

[0040] In this embodiment, the movable connection setting between the movable rod 4 and the grease box 505 is conducive to the stable extension and retraction of the movable rod 4, and at the same time is conducive to the full contact between the movable rod 4 and the grease box 505, thereby facilitating the anti-wear treatment of the movable rod 4, and improving the anti-wear effect of the movable rod 4 and the fixed tube 3, and facilitating the overall stable use.

[0041] See also Figure 3 In order to achieve waterproof and rust-proof treatment of the pipe column, the storage box 506 in this embodiment includes a box body 5061, a connecting cover 5062, a movable bar 5063, a supporting spring 5064 and a cover plate 5065.

An oil outlet is provided at the bottom of the box body 5061, and an oil inlet connected to the oil outlet is provided at the top of the grease box 505.

[0042] It can also be seen that the connection between the oil outlet and the oil inlet facilitates the outflow of grease in the box 5061, thereby facilitating the lubrication of the movable rod 4. At the same time, the characteristics of the lubricating grease achieve a waterproof effect on the movable rod 4, thereby facilitating the improvement of the rust resistance of the movable rod 4, thereby extending the overall service life.

[0043] It needs to be explained that the connecting cover 5062 is threadedly connected to the top of the box body 5061, the movable bar 5063 is slidingly connected to the left side of the box body 5061, the left and right sides of the support spring 5064 are respectively fixed to the movable bar 5063 and the box body 5061, and a clamping block is fixed on the left side of the cover plate 5065. The cover plate 5065 is clamped to the box body 5061 through the clamping block, and the cover plate 5065 is fixed to the bottom of the movable bar 5063.

[0044] In this embodiment, the sliding connection between the movable bar 5063 and the box body 5061 is conducive to the movement of the movable bar 5063, thereby driving the cover plate 5065 to slide, thereby facilitating the stable sliding of the cover plate 5065 and improving the overall stability of use. The setting of the support spring 5064 is conducive to the resetting of the cover plate 5065, thereby facilitating the stability of the lubricating grease in the box body 5061 and further improving the overall stability of use.

[0045] See also Figure 4 In order to improve the overall convenience of use, the disassembly assembly 507 in this embodiment includes a fixed seat 5071, a rotating column 5072, an adjusting rod 5073, a threaded column 5074, a locking cover 5075 and a connecting block 5076. The fixed seat 5071 is fixed to the top of the protective tube 501, and the rotating column 5072 is rotatably connected to the inner side of the fixed seat 5071.

[0046] The rotation connection setting is beneficial for limiting the connection block 5076 by rotating the rotating column 5072, thereby preliminarily locking the connection block 5076, thereby improving the stability of the connection block 5076, and further facilitating the stable use of the entire assembly.

[0047] It should also be explained that the adjustment rod 5073 is fixed to the outer side of the rotating column 5072, the threaded column 5074 is fixed to the front side of the adjustment rod 5073, and the locking cover 5075 is threadedly connected to the outer side of the threaded column 5074.

[0048] The threaded connection arrangement facilitates the connection between the locking cover 5075 and the threaded column 5074 , thereby facilitating the stability of the connecting block 5076 and further facilitating the stable use of the entire assembly.

[0049] The front and rear sides of the connecting block 5076 are respectively fitted with the fixing seat 5071 and the locking cover 5075. The inner side of the connecting block 5076 is fixed to the box body 5061. The left and right sides of the connecting block 5076 are provided with movable openings, and the adjusting rod 5073 is movably connected to the connecting block 5076 through the movable openings.

[0050] In this embodiment, the setting of the movable opening facilitates the placement of the adjustment rod 5073, thereby facilitating the squeezing of the connecting block 5076 through the locking cover 5075. The threaded connection setting enables the locking and disassembly of the connecting block 5076, thereby facilitating the disassembly and assembly of the storage box 506, and the addition and replenishment of lubricating grease, thereby facilitating the improvement of the overall convenience of use.

[0051] The working principle of the above embodiment is:

[0052] When the steering column is in use, the fixed cylinder 3 and the movable rod 4 will be extended and retracted. When the movable rod 4 extends to the right, the fixed block 502 is driven to move to the right, thereby driving the movable plate 503 to slide to the right along the protective cylinder 501. When the movable rod 4 moves to the outer side, the anti-rust component 5 starts the lubrication work, and the action block 504 hits the movable bar 5063, driving the cover plate 5065 to move out of the box body 5061, thereby driving the cover plate 5065 to slide to the right through the fixing action, so that the lubricating grease in the box body 5061 flows out from the oil outlet and enters the grease box 505. Through the displacement of the movable rod 4, the outer side of the movable rod 4 and the lubricating oil in the grease box 505 are aligned. The grease is in full contact, thereby achieving full lubrication of the movable rod 4, thereby preventing the steering column from rusting. The overall fixed cylinder 3 is covered by the protective cylinder 501, which reduces the degree of rust on the steering column caused by external water. When the storage box 506 needs to be replenished, the locking cover 5075 that presses the connecting block 5076 is rotated and removed through the threaded action, and then the adjusting rod 5073 is rotated to both sides through the rotating connection action, so that the storage box 506 and the connecting block 5076 are removed together, and the connecting cover 5062 is rotated to replenish it. The overall structure is simple, and the steering column can be treated to prevent wear and waterproof, which is beneficial to improving the service life.
