[0002] The automotive steering knuckle, also known as the "steering knuckle," is a crucial component of the automotive steering axle. It enables stable vehicle movement and sensitive transmission of steering direction. Its function is to transmit and bear the load from the front of the vehicle, support and drive the front wheels to rotate around the kingpin, thus steering the vehicle. Automotive steering knuckles are typically fork-shaped. Both front-wheel drive and rear-wheel drive steering knuckles have a trapezoidal arm. However, due to the presence of the trapezoidal arm, the steering system cannot achieve large-angle steering. Existing steering knuckles are prone to vibration and wear damage, and the steering knuckle end is not easily replaceable with the steering knuckle strut, affecting its service life. Therefore, improving existing automotive steering knuckles and designing a new type of automotive steering knuckle and steering knuckle assembly to solve the above-mentioned technical defects and improve the overall practicality of automotive steering knuckles is particularly important. Utility Model Content

[0003] The purpose of this utility model is to provide an automotive steering knuckle and automotive steering knuckle assembly.

[0006] The connecting component is used for quick connection between the connector and the fixing block.

[0007] As a preferred embodiment of this utility model, the connecting assembly comprises a receiving groove, a limiting block, a first compression spring, a snap-fit ​​groove, a snap-fit ​​block, a moving rod, a guide block, and a connecting rod. The receiving groove is located at one end of the connecting seat near the fixed block. Both sets of limiting blocks are located inside the receiving groove. The first compression spring is located outside the limiting block. The snap-fit ​​groove is located inside the receiving groove and between the two sets of limiting blocks. The snap-fit ​​block is located at one end of the fixed block near the connecting seat. The moving rod is fixedly connected to one end of the snap-fit ​​block near the fixed block. The guide block is located at one end of the moving rod away from the snap-fit ​​block. The connecting rod is located at one end of the guide block away from the moving rod.

[0008] As a preferred embodiment of this utility model, the internal structure size of the receiving groove is designed to correspond to the external structure size of the fixing block, and the fixing block is connected to the connecting seat through the receiving groove.

[0009] As a preferred embodiment of this utility model, the limiting block is slidably connected to the receiving groove, the first compression spring is connected to the limiting block through the receiving groove, and a guide rod is provided at the end of the limiting block away from the first compression spring, and the guide rod is slidably connected to the receiving groove.

[0010] As a preferred embodiment of this utility model, the external structural size of the snap-fit ​​block corresponds to the internal structural size of the snap-fit ​​groove. The moving rod is connected to the snap-fit ​​groove through the snap-fit ​​block. A guide groove is provided inside the guide block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, through the design of the connecting component, when the steering knuckle body is worn and damaged and needs to be replaced, pressing the connecting rod causes the guide block to move through the guide groove, which in turn causes the guide block to move the moving rod, thereby allowing the snap-fit ​​block to move out of the snap-fit ​​groove. This allows the fixing block to rotate inside the receiving groove. Rotating the fixing block moves it out of the space between the two sets of limiting blocks, allowing it to move out of the receiving groove. This disconnects the connection between the connecting seat and the fixing block, thus enabling the steering knuckle body to be replaced. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] See also Figure 1-Figure 3 This utility model provides a technical solution:

[0022] A car steering knuckle includes a steering knuckle body 1, a steering knuckle support rod 2 on the outer side of the steering knuckle body 1, and a connecting seat 3 at one end of the steering knuckle body 1 near the steering knuckle support rod 2. A fixing block 4 is provided at one end of the steering knuckle support rod 2 near the connecting seat 3. The connecting seat 3 is connected to the fixing block 4 through a connecting assembly 5.

[0023] The connecting component 5 is used for quick connection between the connecting base 3 and the fixing block 4.

[0024] Furthermore, the connecting assembly 5 consists of a receiving groove 6, a limiting block 7, a first compression spring 8, a snap-fit ​​groove 9, a snap-fit ​​block 10, a moving rod 11, a guide block 12, and a connecting rod 13. The receiving groove 6 is located at one end of the connecting seat 3 near the fixed block 4. Both sets of limiting blocks 7 are located inside the receiving groove 6. The first compression spring 8 is located outside the limiting block 7. The snap-fit ​​groove 9 is located inside the receiving groove 6 and between the two sets of limiting blocks 7. The snap-fit ​​block 10 is located at one end of the fixed block 4 near the connecting seat 3. The moving rod 11 is fixedly connected to one end of the snap-fit ​​block 10 near the fixed block 4. The guide block 12 is located at one end of the moving rod 11 away from the snap-fit ​​block 10. The connecting rod 13 is located at one end of the guide block 12 away from the moving rod 11. When the steering knuckle body 1 is worn or damaged, the connection between the connecting seat 3 and the fixed block 4 can be quickly disconnected through the connecting assembly 5, so that the connection between the steering knuckle body 1 and the steering knuckle support rod 2 can be disconnected, thus making it convenient to replace the steering knuckle body 1.

[0025] The internal structure size of the receiving groove 6 is designed to correspond to the external structure size of the fixing block 4. The fixing block 4 is connected to the connecting seat 3 through the receiving groove 6, so that the fixing block 4 can be connected to the connecting seat 3.

[0026] Secondly, the limiting block 7 is slidably connected to the receiving groove 6. The first compression spring 8 is connected to the limiting block 7 through the receiving groove 6. A guide rod is provided at the end of the limiting block 7 away from the first compression spring 8. The guide rod is slidably connected to the receiving groove 6, which allows the limiting block 7 to be connected to the first compression spring 8. The first compression spring 8 can drive the limiting block 7 to move. When the fixed block 4 contacts the limiting block 7, the first compression spring 8 drives the limiting block 7 to move, so that the limiting block 7 can limit the fixed block 4 and limit the fixed block 4 inside the receiving groove 6. This allows the fixed block 4 to be limitedly connected to the connecting seat 3. Therefore, the steering knuckle body 1 can be installed with the steering knuckle support rod 2. When the limiting block 7 moves, the guide rod can guide it, increasing the stability of the displacement and preventing deviation.

[0027] Furthermore, the external size of the snap-fit ​​block 10 corresponds to the internal size of the snap-fit ​​groove 9. The moving rod 11 is connected to the snap-fit ​​groove 9 through the snap-fit ​​block 10. The guide block 12 has a guide groove 14 inside. The internal size of the guide groove 14 corresponds to the external size of the connecting rod 13. The connecting rod 13 is connected to the guide block 12 through the guide groove 14, which limits the snap-fit ​​block 10 and the snap-fit ​​groove 9, so that the fixing block 4 can be limited to the snap-fit ​​groove 9. When the fixing block 4 is snapped into the inside of the receiving groove 6, the limiting connection between the snap-fit ​​block 10 and the snap-fit ​​groove 9 can prevent the fixing block 4 from rotating, which would affect the limiting connection with the receiving groove 6.

[0028] Furthermore, a pressing block 15 is provided on the outer side of the connecting rod 13, and a second compression spring 16 is provided on the outer side of the pressing block 15 and on the outer side of the connecting rod 13. The second compression spring 16 is connected to the connecting rod 13 through the pressing block 15. The connecting rod 13, the moving rod 11 and the fixed block 4 are all slidably connected. The second compression spring 16 is connected to the pressing block 15, and the pressing block 15 can be moved by the second compression spring 16, so that the connecting rod 13 can be moved. The guide block 12 is reset by the guide groove 14, so that the moving rod 11 can move the locking block 10.

[0029] This utility model also provides an automotive steering knuckle assembly, including the automotive steering knuckle provided in any of the above embodiments. Because it has all the technical features of the automotive steering knuckle provided in any of the above embodiments, it has the same technical effect as the above automotive steering knuckle, including the automotive steering knuckle assembly.

[0030] In this embodiment, the specific implementation scenario is as follows: In actual use, when the steering knuckle body 1 is worn and damaged and needs to be replaced, the connecting rod 13 is pressed, and the guide block 12 is moved through the guide groove 14, so that the guide block 12 can move the moving rod 11, thereby allowing the snap-fit ​​block 10 to move out of the snap-fit ​​groove 9, so that the fixing block 4 can rotate inside the receiving groove 6. Rotating the fixing block 4 moves the fixing block 4 out between the two sets of limiting blocks 7, so that the fixing block 4 can move out of the receiving groove 6, thereby breaking the connection between the connecting seat 3 and the fixing block 4, thus enabling the steering knuckle body 1 to be replaced. Compared with the existing automotive steering knuckle, this utility model can improve the overall practicality of the automotive steering knuckle through design.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
