Description

Technical Field

[0001] This utility model relates to the technical field of split-type leaf spring skateboard seats, and in particular to a steel leaf spring seat that facilitates the replacement of skateboards. Background Technology

[0002] The leaf spring seat is a key component in the automotive suspension system used to support and position the leaf springs. Its core function is to connect the vehicle frame and the axle through suspension, bear the load impact of the wheels on the frame, reduce vehicle vibration, and ensure the vehicle's smoothness and adaptability to different road conditions. The leaf spring seat transmits the impact force from the wheels to the frame through the leaf springs, while using the elastic deformation of the leaf springs to absorb vibration energy and reduce vehicle bumps.

[0003] The prior art Chinese utility model patent with application number CN201320820396.5 relates to a split leaf spring skateboard seat, including a leaf spring skateboard support, a wear-resistant plate and a pin, which allows for the replacement of the wear-resistant plate.

[0004] However, in actual use, the replacement of the leaf spring in the above device requires pulling it out from the spring seat. Since the leaf spring is quite long, the repeated pulling process requires a lot of physical strength from the operator. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a leaf spring seat that provides a bearing space for the leaf spring through a bearing device, and the semi-enclosed structure facilitates the direct removal of the leaf spring, reducing the labor intensity of operators during installation and disassembly. An auxiliary device provides auxiliary support and limiting for the unenclosed area of ​​the bearing device, preventing displacement and wear between leaf springs due to vibration between multiple sets of leaf springs during vehicle operation. A connecting device provides auxiliary connection between the auxiliary device and the bearing device, improving the safety and practicality of the device. This is a leaf spring seat that facilitates the replacement of the sliding plate.

[0006] This utility model discloses a leaf spring seat for easy replacement of a skateboard; it includes a support device, an auxiliary device, and a connecting device. The auxiliary device is installed on the support device, and the connecting device is installed on the support device. The support device provides support space for the leaf spring, and the semi-enclosed structure facilitates direct removal of the leaf spring, reducing the labor intensity of operators during installation and disassembly. The auxiliary device provides auxiliary support and limit for the unenclosed area of ​​the support device, preventing displacement and wear between the leaf springs due to vibration between multiple sets of leaf springs during vehicle operation. The connecting device provides auxiliary connection between the auxiliary device and the support device, improving the safety and practicality of the device.

[0007] Preferably, the supporting device includes a support platform, rounded chamfers, side arc-shaped grooves, an L-shaped frame, and side reinforcing ribs. The support platform has rounded chamfers at all four corners, and a set of side arc-shaped grooves on each of its left and right sides. An L-shaped frame is located on the right side of the upper end of the support platform, and a side reinforcing rib is located on the right side of the L-shaped frame. The support platform provides support for the leaf spring. The rounded chamfers at the four corners reduce impact damage to the support platform itself. The side arc-shaped grooves on the left and right sides reduce the overall weight of the support platform. The L-shaped frame provides top and right-side limiting for the leaf spring, facilitating its removal from or installation on the support platform and reducing the operator's workload. The side reinforcing ribs increase the support strength of the L-shaped frame, improving the device's practicality.

[0008] Preferably, the auxiliary device includes a bottom limiting plate, an L-shaped auxiliary plate, an L-shaped reinforcing plate, an extension block, and a bottom connecting bolt. The bottom limiting plate is provided on the left side of the upper end face of the support platform. The lower part of the L-shaped auxiliary plate can be placed on the bottom limiting plate. L-shaped reinforcing plates are provided on the left and upper parts of the L-shaped auxiliary plate.

The extension block is connected to the bottom limiting plate by the bottom connecting bolt. The upper part of the L-shaped auxiliary plate can be inserted into the lower side of the top of the L-shaped frame. The bottom limiting plate provides lateral limitation for the bottom leaf spring. The lower part of the L-shaped auxiliary plate is fixed to the bottom limiting plate by the cooperation of the bottom connecting bolt and the extension block. The L-shaped auxiliary plate provides auxiliary limitation for the side and top of the leaf spring. The L-shaped reinforcing plate increases the strength of the main body of the L-shaped auxiliary plate, thereby improving the practicality of the device.

[0009] Preferably, the connecting device includes a top bolt groove, an internal threaded hole, and a top connecting bolt. Multiple sets of top bolt grooves are provided in the middle of the upper surface of the L-shaped frame. Multiple sets of internal threaded holes are provided on the upper surface of the L-shaped auxiliary plate corresponding to the positions of the top bolt grooves. The lower part of the top connecting bolt passes through the top bolt groove and connects to the internal threaded hole on the L-shaped auxiliary plate. By connecting the L-shaped auxiliary plate and the L-shaped frame with multiple sets of top connecting bolts, the stress on the bottom connecting bolt is reduced when the L-shaped auxiliary plate is subjected to lateral force, thereby increasing the overall stability and practicality of the device.

[0010] Preferably, the device also includes a bearing groove, a bearing plate, and a connecting block. The bearing groove is provided on the upper surface of the support platform, the upper surface of the bearing plate is arc-shaped, and the connecting block is provided on the lower surface of the bearing plate. The connecting block can be inserted into the bearing groove. The bearing groove and the connecting block are connected to limit and fix the position of the bearing plate. The bearing plate provides over-support for the bottom spring steel plate and facilitates the replacement of the bearing plate, thus improving the practicality of the device.

[0011] Preferably, it also includes an auxiliary connecting groove and a wear-resistant head. An auxiliary connecting groove is provided on the top of the right end face inside the L-shaped frame, and a wear-resistant head is provided on the upper right end face of the L-shaped auxiliary plate. The wear-resistant head can be inserted into the auxiliary connecting groove. During installation, the upper wear-resistant head of the L-shaped auxiliary plate is pushed laterally into the auxiliary connecting groove, thereby providing support for the main body of the L-shaped auxiliary plate, facilitating the subsequent connection of bolts, and improving the practicality of the device.

[0012] Preferably, both the auxiliary connecting groove and the lower part of the wear-resistant head are provided with bevels, and the two sets of bevels fit together when they are connected. The bevels provided on the lower part of the auxiliary connecting groove and the wear-resistant head make it easier for the wear-resistant head to be inserted into the auxiliary connecting groove when the L-shaped auxiliary plate is pushed and installed, which reduces the installation difficulty for operators and improves the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the bearing device provides bearing space for the leaf spring, and the semi-enclosed structure makes it easy to directly remove the leaf spring, reducing the labor intensity of operators during installation and disassembly; the auxiliary device provides auxiliary support and limit for the area of ​​the bearing device that is not covered, preventing displacement and wear between leaf springs due to vibration between multiple sets of leaf springs during vehicle operation; and the connecting device provides auxiliary connection between the auxiliary device and the bearing device, improving the safety and practicality of the device.
