Description

Technical Field

[0001] This utility model relates to the field of automotive steering column technology, and more specifically, to a modular unlocking combined automotive steering column device. Background Technology

[0002] According to the existing automotive steering column design, a single-function fixed structure is usually adopted. While achieving basic steering functions, it faces problems such as insufficient flexibility, inadequate safety assurance, and limited user convenience.

[0003] Existing steering columns lack sufficient protective measures to mitigate the impact of vehicle shock on the human body during sudden collisions or accidents, especially inadequate protection of the driver's chest area. Furthermore, steering columns face high maintenance costs and significant material wear in practical use, particularly under high-intensity use and significant environmental changes, leading to frequent repairs and replacements, thus increasing the financial burden on users. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a modular unlocking combined automotive steering column device, which has the advantages of easy replacement and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular unlocking combined automotive steering column device, comprising an upper tube body and a lower tube body. The bottom of the upper tube body is provided with an installation groove, and the inner surface of the installation groove is provided with multiple moving grooves. The moving grooves are slidably connected to moving blocks. The moving blocks are disposed on the outer surface of the lower tube body. A buffer cylinder is provided at the top of the installation groove. The bottom of the buffer cylinder is an open structure. A buffer piston is movably connected inside the buffer cylinder. A buffer solution is installed inside the buffer cylinder above the buffer piston. A liquid outlet is provided on the side of the buffer cylinder. The liquid outlet is connected to a storage cylinder through a liquid outlet pipe. The storage cylinder is installed on the side of the buffer cylinder. A buffer rod is installed at the top of the upper tube body. Limiting holes are provided on the inner surfaces between the moving grooves. Limiting holes are threadedly connected to limiting shafts. Limiting blocks are provided on the outer surface of the lower tube body between the moving blocks.

[0006] As a preferred embodiment of this utility model, the number of liquid outlets is the same as the number of liquid storage cylinders, and there are multiple liquid outlets, with multiple liquid storage cylinders distributed circumferentially on the outer surface of the buffer cylinder.

[0007] As a preferred technical solution of this utility model, the top of the interior of the upper tube is provided with a fixing groove, and the fixing groove is threadedly connected to the upper end of the outer surface of the buffer cylinder.

[0008] As a preferred embodiment of this utility model, a protective box is fitted onto the outer surface of the upper tube, and a protective pad made of rubber is bonded to the inner surface of the protective box.

[0009] As a preferred embodiment of this utility model, a limiting ring is provided on the outer surface of the lower tube body, and the outer diameter of the limiting ring is larger than the inner diameter of the mounting groove.

[0010] As a preferred embodiment of this utility model, a protective sleeve is bonded to the outer surface of the buffer rod, and the protective sleeve is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model improves the stability of the connection between the upper and lower pipe bodies by using a sliding connection between the moving groove and the moving block. By setting a limiting block, after the lower pipe body enters the installation groove, the gap between the limiting shaft and the outer surface of the lower pipe body is reduced by rotating the limiting shaft, thereby limiting the limiting block and preventing the lower pipe body from falling off the upper pipe body during use, which would affect subsequent use. Furthermore, for subsequent maintenance and replacement, the lower pipe body can be separated from the upper pipe body simply by turning the limiting shaft in the opposite direction and moving the lower pipe body downward, which improves the convenience of maintenance and replacement.

[0013] 2. This utility model, by setting a buffer cylinder with a buffer piston, when a car is hit by a collision, the driver leans forward under the action of inertia, which impacts the steering wheel and causes the upper tube to move downward. When the upper tube moves downward, it causes the buffer piston to move downward and come into contact with the buffer rod. Under the action of the buffer rod, the buffer piston moves upward. Under the buffering effect of the buffer, the forward inertia of the driver is offset, protecting the driver's chest area and improving the protective performance of the device.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a modular unlocking combined automotive steering column device, including an upper tube body 1 and a lower tube body 2. The bottom of the upper tube body 1 is provided with an installation groove 7, and the inner surface of the installation groove 7 is provided with multiple moving grooves 8. The moving grooves 8 are slidably connected to moving blocks 4. The moving blocks 4 are set on the outer surface of the lower tube body 2. The top of the installation groove 7 is provided with a buffer cylinder 13. The bottom of the buffer cylinder 13 is an open structure. The buffer cylinder 13 is movably connected to a buffer piston 14. The buffer cylinder 13 above the buffer piston 14 is filled with a buffer solution. The side of the buffer cylinder 13 is provided with a liquid outlet. The liquid outlet is connected to a liquid storage cylinder 16 through a liquid outlet pipe 15. The liquid storage cylinder 16 is installed on the side of the buffer cylinder 13. The top of the upper tube body 1 is provided with a buffer rod 11. The inner surface between the moving grooves 8 is provided with a limiting hole 9. The limiting hole 9 is threadedly connected to a limiting shaft 3. The outer surface of the lower tube body 2 between the moving blocks 4 is provided with a limiting block 10.

[0021] The sliding connection between the moving groove 8 and the moving block 4 improves the stability of the connection between the upper tube 1 and the lower tube 2. By setting the limiting block 10, after the lower tube 2 enters the installation groove 7, the limiting shaft 3 is rotated to reduce the gap between the limiting shaft 3 and the outer surface of the lower tube 2, thereby limiting the limiting block 10 and preventing the lower tube 2 from falling out of the upper tube 1 during use, which would affect subsequent use. In subsequent maintenance and replacement, the lower tube 2 can be separated from the upper tube 1 simply by turning the limiting shaft 3 in the opposite direction and moving the lower tube 2 downward, which improves the convenience of maintenance and replacement.

[0022] By setting a buffer cylinder 13 with a buffer piston 14, when the car is hit by a collision, the driver leans forward due to inertia, impacting the steering wheel, which in turn drives the upper tube 1 to move downward. When the upper tube 1 moves downward, it drives the buffer piston 14 to move downward and contact the buffer rod 11. Under the action of the buffer rod 11, the buffer piston 14 moves upward. Under the buffering effect of the buffer, the forward inertia of the driver is offset, protecting the driver's chest area and improving the protective performance of the device.

[0023] The number of liquid outlets is the same as the number of liquid storage cylinders 16, and there are multiple liquid outlets. Multiple liquid storage cylinders 16 are distributed circumferentially on the outer surface of the buffer cylinder 13.

[0024] By setting multiple storage cylinders 16, the buffer solution can be easily discharged through multiple outlets, improving the efficiency of buffer solution discharge. Furthermore, the multiple storage cylinders 16 are distributed circumferentially on the outer surface of the buffer cylinder 13, making the buffer cylinder 13 subjected to uniform force and improving the stability of the buffer cylinder 13.

[0025] The upper tube 1 has a fixed groove at its top end inside, and the fixed groove is threaded to the upper end of the outer surface of the buffer cylinder 13.

[0026] By setting a fixing groove, it can be threaded to the outer surface of the buffer cylinder 13, which improves the convenience of installing and disassembling the buffer cylinder 13.

[0027] The outer surface of the upper tube 1 is fitted with a protective box 6, and the inner surface of the protective box 6 is bonded with a protective pad made of rubber.

[0028] By incorporating a protective box 6 with a protective pad, the driver's chest area can be protected in the event of a collision, thus improving the device's protective performance.

[0029] The lower tube 2 has a limiting ring 5 on its outer surface, and the outer diameter of the limiting ring 5 is larger than the inner diameter of the mounting groove 7.

[0030] By setting a limit ring 5, the upward movement distance of the lower tube 2 can be limited to prevent it from moving too far in the event of an accident and causing injury to the driver.

[0031] The outer surface of the buffer rod 11 is bonded with a protective sleeve 12, which is made of rubber.

[0032] By installing a protective sleeve 12 made of rubber, the buffer bar 11 can be protected to prevent it from causing injury to the driver in the event of an accident.

[0033] Working principle and usage process of this utility model:

[0034] The sliding connection between the moving groove 8 and the moving block 4 improves the stability of the connection between the upper tube 1 and the lower tube 2. By setting the limiting block 10, after the lower tube 2 enters the installation groove 7, the limiting shaft 3 is rotated to reduce the gap between the limiting shaft 3 and the outer surface of the lower tube 2, thereby limiting the limiting block 10 and preventing the lower tube 2 from falling out of the upper tube 1 during use, which would affect subsequent use. In subsequent maintenance and replacement, the lower tube 2 can be separated from the upper tube 1 simply by turning the limiting shaft 3 in the opposite direction and moving the lower tube 2 downward, which improves the convenience of maintenance and replacement.
